PREFACE
Inspiration is an odd beast enlightening here and deceiving
there Inspiration sometimes comes through epiphany seem-
ingly out of nowhere and resplendent with originality and beauty
Some works of great music appear in this way Friedrich
Nietzsche wrote his anti-Gospel Tus Spoke Zarathustra in a
fit of literary effusion lasting only two weeks Te result hasbaffled millions for a century
Philosophy in Seven Sentences came into being rather quickly
after a lifetime of engaging philosophy after many discussions
and arguments about philosophy after three academic degrees
in philosophy after attending (too) many conferences about phi-
losophy after grading many papers about philosophy (both
good and evil) after publishing much about philosophy after
changing some of my views on philosophy and after sometimes
questioning my own ability to do philosophy well
I was inspired by recent popular books featuring numbers
and objects in the titles such as A History of the World in
Objects by Neil MacGregor A History of the World in Six Glasses
by om Standage and Te Smithsonianrsquos History of America in Objects by Richard Kurin My object for organizing and in-
troducing philosophy was not a physical object but an object of
thought a sentence Te number seven seemed right given the

alliteration and because I was drawn to just these philosophi-
cally pregnant sentences My hope is that the book will introduce
the beginner to the craft of philosophy A seasoned reader might
find ideas worth consulting afresh or even for the first time
Philosophy is a many-splendored discipline Miniature books
such as this must fail to lasso everything and will leave many
critters hurdling about in the pasture unnamed and unattended
o talk shop Philosophy in Seven Sentences is most concerned
with epistemology (how and what we can know) and metaphysics (the study of being) ravelers through the book will also read a
bit about moral philosophy and aesthetics
Philosophers have biographies although their philosophies
are not limited to their biographies So each chapter includes a
bit of their stories (A few of my stories appear as well) Since
philosophers argue and agree with other philosophers I con-
sider their intellectual relationship with others in the guild par-
ticularly those philosophers whose sentences we engage Dia-
logue and debate down through the ages is the conversation of
philosophy Overhearing it may spark truth in our souls or at
least clear away some errors of thought
I do not take up theology directly but each of the seven sen-
tences bears on questions concerning God the universe andhumanity I am not sure why anyone would be interested in phi-
losophy otherwise
I have many to thank but room for only a few Jason Crowder
found references for Augustine and Pascal that eluded me (to my
shame) My colleague Sarah Geis gave excellent commentary on
Descartes Elizabeth Johnson contributed some dandy editing
Rebecca Merrill Groothuis prayed for this book project as she
has for all my other ones Tanks also to the administration of
Denver Seminary for granting me a sabbatical during which
much of this work was done

Introduction
PHILOSOPHY IN ONLY
SEVEN SENTENCES
Can we tackle some of the key questions and answers in
philosophy through just seven sentences by seven famous
philosophers I wager we can so we will Many other sentencesmdash
or paragraphs or booksmdashcould have made the cut Because of
this some will argue that my selection was biased ignorant or
slanted If so let them philosophize over it After all that is the
purpose of this book to think and act philosophically
I make no claim that Philosophy in Seven Sentences is repre-
sentative of philosophy as a whole I chose these authors and
their sentences for several reasons First I was familiar with
them As I point out several times many of these ideas havedeep autobiographical significance to me Second they raise
issues pertinent to our day Tird each sentence is fairly well
known none is esoteric1 I also chose these authors because
their arguments were clear enough to be well suited to philo-
sophical analysis even on a popular level2
Some may think that popular philosophy is an oxymoron a
silly contradiction not worthy of a momentrsquos thought Phi-losophy is of course for expertsmdashthose who have accumulated
vast student-loan debts after which they have logged long and
lonely years in the classroom studying at their desks and ar-

guing with other philosophers about philosophy Tese strange
souls are abstruse esoteric recondite and many other long
pompous words not meant for the masses Philosophers write
for each other argue with each other and often flummox or bore
the hapless college students whose academic requirements put
them in their presence
And so it is for many philosophers but not for all of them At
its most ancient root philosophy was meant to initiate us into
ldquothe good liferdquo to tutor us for the ongoing experience ofknowledge and virtue Since everyone lives some kind of life
philosophy explored the mindrsquos abilities to live life in accord
with reality At best it helps scratch the itch of human exis-
tencemdashor at its worst it rubs the wound raw Even though ety-
mology (the study of word origins) may deceive it does its work
well in understanding the origin of philosophy telling us that
its two Greek parts are love ( philos) and wisdom ( sophos) Phi-
losophers may not always love wisdom but that is their disci-
plinersquos pedigree Te Hebrew Bible warns in the book of
Proverbs that both wisdom and folly call out for reflection and
allegiance Te wise are diligent in learning facing the facts in
earnest while the fool sacrifices character for ignorance and
untutored pleasure But knowledge beckons nevertheless atleast in our better moments As Aristotle wrote ldquoAll men by
nature desire to knowrdquo (We will examine this sentence shortly)
Any thinking person may join philosophyrsquos discussion which
rings down through the ages Tat is the aim of this small book
which I hope can be read profitably by both philosophical neo-
phytes and seasoned philosophers whatever their worldview
may be My aims are catholic (universal) however parochial my
selections may seem to some
Philosophy is not a closed club or a secret society Since we
all can think about ultimate questions letrsquos do it For the record

Philosophy in Only Seven Sentences
I propose that the requirements for being a philosopher (whether
good or bad major or minor professional or layperson) are a
strong and lived-out inclination to pursue truth through the rig-
orous use of human reasoning and to do so with some intel-
lectual facility But sadly even some philosophers disavow the
search for truth In Whatrsquos the Use of ruth French philosopher
Pascal Engel writes ldquoTere is no obligation to say or to be-
lieve that which is truerdquo3 If so why should we read his writings
or those of any other philosopherIs then everyone a philosopher Everyone muses a bit on
where we came from who we are and where we are going But
not all do this very well So while Johnny Rotten (b ) of the
Sex Pistols addressed some philosophical themes in his punk
rock compositions and performances one is reluctant to give
him the title of philosopher Tis is because it is a kind of merit
badge reserved for the few I was recently asked by a precocious
ten-year-old named Liam if I was a philosopher I said I was
Ten he asked ldquoWhat do you dordquo My reply was ldquoI think a lot
about argumentsrdquo We then discussed the nature of an argument
With a little coaxing he told me what an argument was giving
reasons for what you believe often in conversations with those
who believe otherwise I have recruited him for graduate studyin my program
o enjoin the discussion of philosophy I will appeal to seven
sentences all of which are short but none of which are trivial
Some are more renowned than others A few of them are famous
Tese statements are not impenetrable deceiving the unwary
inquirer with obscurity masquerading as profundity Sadly not
a few philosophers cloak their ideas with idiosyncrasies and un-
necessary jargon Not so for a Socrates or Jesus who went about
speaking the common tongue in uncommon ways to both
common and uncommon people Te public square was their

classroom and all comers were their students Neither wrote a
word but their words are unforgettable as we will see Teir
ideas are affirmed and denied by the simplest and most sophis-
ticated thinkers
While we cannot directly encounter the likes of Socrates or
Jesusmdashor the more bookish philosophers such as Plato Aris-
totle Augustine Descartes and kindredmdashwe can interrogate
them and investigate the perennial questions they address the
nature of truth how we gain knowledge the meaning of humanexistence death the source of morality and more In my many
years as a teacher and learner of this antique art I find to my
dismay that too many students too often give up too soon Tey
face an intellectual difficulty some demanding reading or differ-
ences of opinion and they cash in their chips despite my provo-
cations cajoling and (on occasion) anger It need not be and
should not be so S Eliot should kindle a flame in us ldquoBut our
lot crawls between dry ribs to keep our metaphysics warmrdquo4
I first read Eliotrsquos line in and never forgot it Who could
unless he or she were skimming Martin Heidegger despite his
murky prose was right in calling our lives a ldquobeing unto deathrdquo
because our eventual demisemdashgradual or instantmdashbrackets
everything we think or do or hope ldquoNo one gets out of here aliverdquois no tired clicheacute unhappily Samuel Johnson put it well ldquoDepend
upon it Sir when a man knows he is to be hanged in a fortnight
it concentrates his mind wonderfullyrdquo5 Our mortality sets limits
on all our endeavors including philosophizing Tere is like it
or not a flashing stop sign ahead on the road So why not think
well now Or at least try to We can take or steal some calmly
measured time to muse on what matters most and we have
some guidesmdashepitomized by their sentencesmdashto light the way
or at least to rebuke our intellectual laziness Let me introduce
them in historical order

Protagoras is not a household name Google him and find out(Te first entry is not surprisingly Wikipedia) Nor do you find
many academic titles analyzing his ideas although he is often
grouped with the Sophists Tis is considered a disreputable
crowd by some wags and is even a byword ldquoYou sophistrdquo Te
charge is that Sophists cared nothing for truth but cared every-
thing about being paid to philosophize for a vested interest
More on these philosophers-for-hire later Even so this oldGreek crystallizes the thought of not a few philosophers and
nonphilosophers Our chosen sentence sums it up
Man is the measure of all things of the things which are
that they are and of things which are not that they are not6
Protagoras gives wings to an idea that many ponder try our
hardest (or not try at all) we cannot break free of ourselvesmdashour
senses our viewpoints our values even our ldquostuffrdquo Te world is
our judgment and nothing more It does not await our judgment
it is our judgment Tere is no objective truth but only various
views from various places at various times by various people
Tings are not our measure but we are the measure of them
Hence Protagoras is the spokesman for relativism sometimescalled nonrealism or perspectivism It is not just that we have no
(or limited) access to objective reality Tat is skepticism Reality
is pretty much exhausted by our perceptions and thoughts Te
real world is our world Myriads have measured Protagoras
wrong at least on this but no one in pursuit of knowledge and
wisdom can ignore him His ghost haunts us still Is there a phil-
osophical exorcist aboutOur next sentence is often heard but seldom digested I un-
failingly quote it in my first class of introduction to philosophy

students to live this waymdashfor their sakes and mine (It makes for
better papers too) Tus said Socrates the gadfly (or pain-in-
the-neck) of ancient Athens Like Protagoras we know of
Socrates through those who knew his work but unlike Pro-
tagoras we have more substantial sources particularly Plato
And Socrates is a household name Not incidentally the man
who was not an author ended up being the inspiration for the
prolific Plato who was the worldrsquos first systematic philosopher
As philosopher Alfred North Whitehead discerned ldquoTe safestgeneral characterization of the European philosophical tradition
is that it consists of a series of footnotes to Platordquo7 Te footnotes
may praise (Augustine) or blame (Aristotle) but footnotes are
everywhere as well as entire volumes
aking up Socratesrsquos philosophical challenge means exam-
ining just what his famous sentence means in itself and what it
means for us What might an examined life be given the distrac-
tions and overstimulation of postmodern times For Socrates
there is a way to calm the mind and search things out But is
there a place for Socratic dialogue today outside the Socratic
method of many law schools Further old Plato Socratesrsquos
chronicler and student may offer us wisdom pertaining to the
nagging questions of philosophy as he spurns the work of the philodoxers (lovers of opinion) and promotes the call of the phi-
losophers (lovers of wisdom) Worse yet were the misologists (one
of the Platonic corpusrsquos most winning words) those who took an
active role in hating the use of reason itself We may find some
today even in educated enclaves or even on the bestsellers lists
But one can also find Aristotle in popular bookstores always
in the philosophy section (along with less prestigious volumes
such as Led Zeppelin and Philosophy which we must pass over
without further comment) When Aristotle wrote ldquoAll men by
nature desire to knowrdquo he did not mean just the scholars or

teachers but ldquomanrdquomdashthe human race in all its circumstances and
variations Tat means every person whatever social standing
vocation or intelligence Although Aristotle was no egalitarian
(he thought that women were inferior to men and that some were
born to be slaves) he nevertheless appeals to a universal human
condition the desire to get reality right in the time that we have
Augustine the first great Christian philosopher like Socrates
before him strikes a personal note concerning getting reality
right Having examined himself and the leading philosophies ofhis day (including Plato and his footnotes) he confesses with a
cry of the heart addressed to God ldquoYou have made us for
yourself and restless is our heart until it comes to rest in yourdquo
Tis cry is not commonplace as in ldquoMy spirituality gives me
meaningrdquo It is instead the beginning of an argument told in his
autobiography In fact it may be the first autobiography on
record It is no doubt the first philosophical autobiography (if
we exclude the book of Ecclesiastes) Te irascible Jean-Jacques
Rousseau is well known for his autobiography as well but a short
book can only do so much8
Skipping madly over much philosophical history (without any
irreverence or glibness) we arrive at Reneacute Descartes the much
maligned but seldom understood ldquofather of modern philosophyrdquoDescartes was troubled by opinions without backingmdashthose
ideas about ultimate matters untethered from certainty Skep-
ticism was his foe as it is in one way or another for any philos-
opher Tis is because the question arises How do you know
what you claim to know Mere social position or historical tra-
dition will not cinch the deal for this philosopher and scientist
In our language (which itself needs interrogation) the man
ldquowanted proofrdquo While ldquoI donrsquot knowrdquo is often the most knowl-
edgeable answer it should not be the default response according
to Descartes Tis apprehension led him on a quest that began

with himself Like Augustine but in briefer scope he put this in
autobiographical form in Discourse on Method and to some
extent in Meditations on First Philosophy But Descartesrsquos quest
did not end with himself unlike so much contemporary self-
help literature He is famous for the sentence ldquoI think therefore
I amrdquo But God himself has something to do with that sentence
For Descartes there was no leap of faith in it either Reason was
the guide But how far can reason take us
A contemporary of Descartes had an idea ldquoTe heart has itsreasons that reason knows nothing ofrdquo wrote Blaise Pascal who
was the best phrasemaker of the lot of our philosophers Tis
statement is a window into a worldview Humans have the ca-
pacity to calculate and reason methodically but they may also
know some things by tracing out the contours and resources of
ldquothe heartrdquomdashanother organ of knowledge Philosophers study
many thinkers but few come to love few of them (My graduate
seminar on Kantrsquos Critique of Pure Reason was well worth it but
was no love affair) Pascal on the contrary is much loved by many
He is so loved that people even love things he never actually said
such as ldquoTere is a God-shaped vacuum that only God can fillrdquo
But this paraphrase is not far off the mark though it should be
placed within a larger perspective of Pascalrsquos philosophyTe French polymathrsquos philosophy is far more fascinating than
the CliffsNotes version allows Pascal did not put faith in place
of reason and he was not a one-trick philosopher (Pascalrsquos
wager) Slander and libel have fouled the air about him ob-
scuring his sophisticated treatment of the cost-benefit sense of
believing in religion or not Yet he was neither knave nor poser
Te founder of probability theory and the inventor of the first
working calculating machine had reasons for faith Like Des-
cartes he was bugged by skepticism and like Descartes he ap-
pealed to human nature as a place to start the discussion

Philosophy in Only Seven Sentences
Our last sentence is not as well known as the previous ones
but it opens a door of inquiry for us
Te greatest hazard of all losing onersquos self can occur very
quietly in the world as if it were nothing at all
It was penned by an idiosyncratic and famously melancholy
Dane named Soslashren Kierkegaard a philosopher intensely inter-
ested in the self in relation to ultimate reality Tis should sound
familiar since all philosophers have expressed this interest inone way or another But Kierkegaardrsquos way was in a sense as
much psychological as philosophical He intrepidly limned the
inner workings of the self of consciousness in philosophical
categories Like Pascal Kierkegaard wanted to strip away
through existential analysis the layers and dynamics of the self
that keep reality at bay Unlike Pascal and the other philosophers
he was more interested in the analysis of the self than presentingit with arguments for an abstract objective reality Tis may
sound a bit unphilosophical but it is not But that takes time to
tease out properly as I hope you will see
Our seven sentences may be viewed as several doors into
worlds previously unknown Or they may be our irritants to
prod us to move away from facile factoidsmdashldquoDo your own thingrdquoldquoFollow your blissrdquo ldquoKeep Calm and Carry Onrdquomdashto more so-
bering reflections9 Perhaps the sentences are bridges to other
lands of thought Tese philosophical sentences do not sum the
thought of any of the philosophers for these thinkers are far too
deep for that Nor do the seven sentences aim to summarize the
history of philosophy Tat would be a pompous and laughable
claim Some things cannot be put into a nutshell including thenutshell itself But I claim that philosophical activity can be
sparked by just seven sterling sentencesmdashand who knows where
it might lead

P
Greeks could do philosophy Te basic questions of exis-
tence have never been far from the human mind but the
ancient Greeks excelled at this and their musingsmdashsome frag-
mentary or secondhandmdashhave been preserved in written texts
However much philosophy occurred in exclusively oral cultures
the Greeks valued writing in addition to oral memory and tra-
dition Socrates you remember wrote nothing but generated a vast literature though his dialogues A lesser-known figure who
came after him did write a few things and his famous adage is
worth considering
Protagoras (fifth century BC) is not to be confused with
like-sounding ancient Greek thinkers named Pythagoras or
Parmenides who along with others were pre-Socratic thinkers
(Tis shows the significance of Socrates since philosophy isdated with respect to his life) Tese thinkers are worth inter-
rogating as well and I studied them with profit in a year-long
course in ancient philosophy forty years ago Protagoras

stands out to us though because of his adage about absolute
assessment
Man is the measure of all things of the things which are
that they are and of things which are not that they are not1
His claim is not simply that people measure thingsmdashsuch as
character chariots boats and fishmdashbut that each human is the
measure Each person is the assessment or judgment What
could this mean No person is a slide ruler or scale or Geigercounter although we avail ourselves of such things
W I M
We tend to think that people use a standard of measurement
outside of themselves Even inadequate and one-dimensional
measures such as onersquos IQ score are not determined by how we
feel about themmdashand Mensa is very picky about thisOn the other hand Protagoras has Shakespearersquos Hamlet on
his side at least concerning morality ldquoFor there is nothing either
good or bad but thinking makes it sordquo2 Tat is morals do not
have objective standing rather they are judged differently by

term sophist meant something like our ldquoprofessorrdquo but later a
Sophist was deemed a hired gun a philosopher for hire and one
having no principles of his own Teir arguments supposedly
were merely the instruments of the will of their bosses One may
argue over the virtues of the Sophists but it is certainly not true
that being paid for philosophizing necessarily disqualifies the
employeersquos arguments On the other hand if we think of a
Sophist as something like a political speech writer or the like
our judgment will change Whatever the intellectual rectitudeof Protagoras he was a perpetual lecturer who articulated and
debated ideas in the marketplace a marketplace of ideas that yet

Protagoras was one of a spirited group of fastidious thinkers
who tired or at least grew skeptical of Greek mythology with
its pantheon of gods Yes the stories of the gods were often riv-
eting and worth repeating A recent volume by Luc Ferry is
called Te Wisdom of the Myths How Greek Mythology Can
Change Your Life3 Tere was always a moral to the story Her-
cules the last son of Zeus was a dashing and dramatic character
who started as a mighty mortal and became a god upon deathAlthough a bit impetuous and lacking in sobriety he plays well
as a hero Zeus himself is the apotheosis of power but acts
largely without moral authority Even the might of Zeus does not
support the idea that ldquomight makes rightrdquo since might may make
for divine mischief My point is not to survey or psychoanalyze
the denizens of Greek mythology but to make a general point
Mythologies may inspire and guide to some extent our relation
to the hard facts of family life death and sexuality (and some of
the gods tended to be naughty in this way)
Nevertheless the problem with Greek mythology (or any

mythology Eastern or Western) is simply that it is mythology it
is neither history nor clearly articulated philosophy In too many
ways the gods despite their thespian reacutesumeacutes and magical
powers were not much more than semi- glorified mortals Tis
was the objection of a growing group of Greeks who were mere
mortalsmdashmortals with meaning metaphysics and morality on
their minds And what might the mind do when free to explore
life and its questions apart from the venerable stories of Greek
fascination It might philosophize and so it didProtagoras and his cohorts quested for explanations of a more
abstract but also compelling sort than the old tales could afford
Tey sought principles to explain facts in a universal and logi-
cally coherent manner o be a little unfair to the mythologies
consider the tooth fairy She adds some magical benevolence to
the loss and placement of a baby tooth for children but the fairy
story adds nothing about the nature of benevolence the signifi-
cance of teeth or the significance of the humans who grow and
lose these teeth whether through development (teething) or
decay (the toothless)
Tus to give one example Tales of Miletus tried to find a
cosmic commonality to all things He divined it as water Yes
water which was more than rain oceans lakes and puddles Itwas everywhere so perhaps it was the root and branch of every-
thing Water or moisture in general lives in the clouds in plants
in animals (aquatic land or amphibious) and in thirsty mortals
It condenses and evaporates but never leaves the planet Con-
sidering the presence and power of water Tales extrapolated
that water was more than one more thing on earth however
necessary for life It was rather the unifying principle for exis-
tence Whatever we think of Tales his thinking is not absurd
and it indicates a thirst for philosophical explanation as opposed
to mythological meanderings At least he was trying

But it is Protagoras who calls for our attention Instead of ar-guing for something at the heart of everything (water for Tales)
a principle found in nature Protagoras moved back from nature
to the self After all skeptics had questioned mere mortalsrsquo
ability to know with any confidence what is out there inde-
pendent of themselves Te jaundiced eye sees things differently
from the nonjaundiced eye Children perceive entities invisible
to adults Adults sometimes hallucinatemdashbut perhaps they areseeing what most miss One woman feels cold in a room of degF
and another feels hot Age alters hearing seeing memory and
may jangle judgments Te upshot is that we cannot find a place
to stand to see the world as it is We are simply ill-equipped to
do so Objective truth what is independent of our perceptions
endlessly and mercilessly eludes us
We will return to skepticism when discussing Descartes and
Pascal but Protagoras was not a skeptic He did not withhold
judgments about facts in themselves because we do not have the
ability to know them While recognizing that the skeptics had
dethroned our intellectual confidence in capturing objective re-
ality his point of departure was this we do know our own view-
points judgments and beliefs Tat is we measure things theydo not measure themselves So I take most of Francis Baconrsquos
paintings to be ugly and thus unattractive I am repulsed Tis is
the end of the story or my story Tis is my measurement You
on the contrary may find delight in Baconrsquos tortured figures and
color schemes Tat is your measurement and the end of your
story
Now reconsider the skeptical point made earlier One person
can deem the room cold and another hot Te skeptic might say
we cannot know then what the room is given the variability in
perception But Protagoras claims that the room is hot for person

A and not hot for person B Tere is no contradiction since we
are considering individual perceptions Tere are two measure-
ments each of which is valid Tus Bacon is barbaric to me and
beautiful to youmdashand that is the level best we can do Or perhaps
I will come to adore Baconrsquos paintings and heap scorn on my
former judgment If so then that is my measurement
Tis is rather attractive at first blush After all there is no
dispute in matters of taste or to be more snobby De gustibus
non est disputandum Te avant-garde saxophone playing ofPeter Broumltzmann can send me into the upper reaches of aes-
thetic delight while sending others scurrying from the room
while covering their ears But Protagoras took this insight far
beyond artistic judgments Notice the reference range (or extent)
of Protagorasrsquos statement ldquoMan is the measure of all thingsrdquomdash
matters of taste as well as matters of fact matters of principle
and matters of matter Nothing is excluded
Let us follow this out As we think it through the old Greek
will sound much like modern man If Protagoras is right then
there is no disputing matters of morality either Man is the
measure of what is right and what is wrong what is virtuous and
what is vicious what should be loved and what should be hatedmdash
just as Hamlet claimed oday this thinking is usually put in thelanguage of choice instead of measurement but the idea is the
same If you chose to do X that choice is the end of the matter
Or to suit Protagoras if you measure X as worth doing then it
is worth doing Tis is true whether X refers to sailing stealing
or stampeding cattle in the direction of a Cub Scout outing
But we might say ldquoWho is to judgerdquo Who of us can stand
above him- or herself and others and become objective Yes we
recoil from some ideasmdashsuch as torturing the innocent merely
for pleasure or female genital mutilation But what does that tell
us about reality if there really is such a thing as reality Te claim

that ldquoman is the measure of all thingsrdquo is an all-encompassing
judgment itself Te answer to ldquoWho is to judgerdquo is that we are
the measure of all things Tat is there is nothing outside of
human judgment by which it might be judged But why would
Protagoras (or anyone else) consider that to be reality itself

Besides being a serial killer ed Bundy was a philosophical
thinker of the Protagorean type Remarkably his philosophy wascaught on tape before he raped and killed a young woman She
was one of dozens of his prey As reported in Louis Pojmanrsquos text
Moral Philosophy Bundy said
I learned that all moral judgments are ldquovalue judgmentsrdquo
that all value judgments are subjective and that none can
be proved to be either ldquorightrdquo or ldquowrongrdquo I even read some-where that the Chief Justice of the United States had written
that the American Constitution expressed nothing more
than collective value judgments Believe it or not I figured
out for myselfmdashwhat apparently the Chief Justice couldnrsquot
figure out for himselfmdashthat if the rationality of one value
judgment was zero multiplying it by millions would not
make it one whit more rational Nor is there any ldquoreasonrdquo
to obey the law for anyone like myself who has the
boldness and daring ldquothe strength of characterrdquo to throw
off its shackles
I discovered that to become truly free truly unfettered
I had to become truly uninhibited And I quickly discovered
that the greatest obstacle to my freedom the greatest blockand limitation to it consists in the insupportable ldquovalue

steer Is your life more to you than a hogrsquos life to a hog
Why should I be willing to sacrifice my pleasure more for
the one than for the other Surely you would not in this

as ldquoimmoralrdquo or ldquobadrdquo4
When teaching ethics to undergraduates at a secular school I
often hand out this Bundy quotation but without identifying the
speaker I then ask them to write a paragraph on whether they
agree with its basic idea Most students approve of the unknown
authorrsquos sentiments I then reveal that this statement was the
philosophy of one of the most infamous serial killers in American
historymdashthe philosophy that allowed and even impelled hisegregious crimes Next I ask them to reconsider their judg-
ments Te results are usually mixed but the majority of stu-
dents show dismay and surprise that they were in agreement
with a view that justified serial rape and murder
Yet today a television seriesmdasha comedy nonethelessmdashis about
a serial killer named Dexter o top that off there is even a book
called Dexter and Philosophy Mind over Spatter Can such atroc-
ities be lifted so easily from bloody reality and into a neutral
realm of entertainment For many it can and so they seem to
agree with Protagoras at least implicitly there is no objective
good and evil nothing sacrosanct or sacrilegious nothing above
us and nothing beneath us It is all merely neutral and we make
the callmdashon everything ldquoMan is the measure of all thingsrdquoSo then what does this sentence tell us about philosophy and
what philosophy means to us Philosophical claims if clearly
articulated give us significant matters to ponder logically and

existentially Tey often capture some truth and so seduce us
on this basis But a statement cannot be true unless it accords
with the way the world in fact is and the way we in fact are Pro-
tagoras does capture some truths about perspective For ex-
ample my tastes in food determine how I measure the goodness
of the food I am the measure of that at least It matters nothing
whether a connoisseur thinks me an ignoramus I can only
measure it by what I experience at the moment In that way I am
the measure but am I the expert Am I the knowerTere is a strange implication for Protagorasrsquos view In the
Teaetetus Protagoras even states that error is impossible5 Al-
though he was a teacher he cannot by his own lights teach
anyone o this Socrates inquires
If whatever the individual judges by means of perception is
true for him if no man can assess anotherrsquos experiencebetter than he or can claim authority to examine another
manrsquos judgment and see if it be right or wrong if as we
have repeatedly said only the individual himself can judge
of his own world and what he judges is always true and
correct how could it ever be my friend that Protagoras
was a wise man so wise as to think himself fit to be the
teacher of other men and worth large fees while we in
comparison with him the ignorant ones needed to go and
sit at his feetmdashwe who are ourselves each the measure of
his own wisdom6

human languages For example the general concept of cat may
be written in Chinese or in English Since each language uses
different symbols for writing its graphic inscription for cat will
differ Tis is true for voicing the word cat as well Trough a
long messy process not instigated by any central planning each
culture selects its own conventions of communication Are not
these two systems of writing measuring reality in very different
ways In point of fact they are not
Both kinds of writing systems (as well as other means ofcommunication) make claims about a reality that are outside
of the systems themselves and outside of the individuals who
use the pictographic or ideographic methods We tacitly saw
this earlier But in both cases a cat is invoked there is a single
referent Te differences in linguistic custom are not differ-
ences in content A cat is a cat in whatever language and it will
not bark however it may be measured Moreover while it may
be vexing in places one can translate a book from English to
Chinese Not everything is lost in translation in fact more is
found than is lost ranslators need have no fear of losing their
livelihood
Staying on matters of taste for a moment (and not morality
for now) are all people equally skilled in measurement Tepoet and literary critic S Eliot advocated the cultivation of
ldquoeducated tasterdquo Consider your preferences in music and
reading when you were quite young Tey are likely not the
same as when you became an adult You may still enjoy and
laugh at nursery rhymes but your tastes have expanded Yes
you still love Winnie the Pooh (and I mean the original Pooh
not the Walt Disney version) but you understand and appre-
ciate it more deeply now If so (and substitute your own ex-
amples here if needed) your tastes have at least changed and
have likely improved with age Your earlier judgments were

likely age appropriate but they were limited and (not unex-
pectedly) childish Te apostle Paul notes this in a well-known
turn of phrase ldquoWhen I was a child I talked like a child I
thought like a child I reasoned like a child When I became a
man I put the ways of childhood behind merdquo ( Corinthians
see also Hebrews -)
Furthermore the very notion of improvement or progress
(not merely some change in quality) requires and assumes an
objective standard by which to measure improvement (or de-cline) If a baseball batter hits in and in he
has improved based on the best possible average of Tere
is a measurement and it is not the perception of the batter that
determines this measurement Tis is the case in the arts as well
Few knowledgeable about jazz would dispute that John Col-
tranersquos saxophone work improved during his tenure with pianist
Telonious Monkrsquos quartet or that it developed further in Col-
trane own ldquoclassic quartetrdquo (ndash)7 Here the assessment is
not quantitative or statistical but qualitative One might object
that this is a purely subjective judgment (such as whether one
feels hot or not) which is relative to the person hearing Who is
to judge Te answer is straightforward the one whose expe-
rience knowledge and wisdom merit approval Although manydrink wine there are few expert wine tasters A student of mine
is so adept at this art that he can tell what part of the country a
wine came from Not having developed this advanced degree of
skill this is foreign to me However I had no inclination to say
that my judgment on wine is as accurate as Markrsquos Along these
lines I was once embarrassed when one of my students told me
that the wine I was enjoying was ldquothe Kenny G of winesrdquo Tis as
jazz aficionados know was not a compliment about the wine or
about my taste for wine
Artistic judgments involve much more than my quick treatment

But Herodotus may yet rescue Protagoras In his History the
ancient historian notes that Darius a king of ancient Persia (who
was a kind of premodern anthropologist because of his study of
cultural differences) called together some Greeks and askedthem what it would take to cannibalize their dead fathers Te
Greeks needed no time to ponder the proposition since nothing
would move them to such odious paternal desecration Teir
practice was cremation this alone would honor their dead Ten
Darius summoned several Callatians (from India) to join the
Greeks and asked them what would make them cremate their
deceased fathers Te Callatians were as horrified as the Greeks
had been and told Darius to not discuss such atrocities
Had Protagoras heard this he would likely applaud having
found more evidence for his outlook But not all applause is
earned While the Greeks and Callatians observed fundamen-
tally different funeral rites both cultures honored the dead Tat
is only particular practicesmdashnot just any old or new thingmdashwere esteemed right and good in the treatment of corpses and
these practices were not norms for the treatment of the living
In other words death was set apart as uniquely meaningful and
thus required that the living treat the dead with ritual respect
Tus Greeks and Callatians agreed on a deep principle of hon-
oring the dead Tey disagreed on the rule that stems from that
principle In no sense then does the example of cultural rela-
tivity disprove moral agreement across cultures since there was
deep agreement between the cultures C S Lewis makes just
this point in Mere Christianity

Protagoras
I know that some people say the idea of a Law of Nature or
decent behaviour known to all men is unsound because
different civilisations and different ages have had quite dif-
ferent moralities
But this is not true Tere have been differences between
their moralities but these have never amounted to any-
thing like a total difference If anyone will take the trouble
to compare the moral teaching of say the ancient Egyp-
tians Babylonians Hindus Chinese Greeks and Romanswhat will really strike him will be how very like they are to
each other and to our own9
Te case against Protagoras comes down to this If we want to
learn anything if we want to improve as human beings if we
want to condemn the ed Bundys of the world if we want any
kind of educated taste if we desire to understand and honorhumanity then we must reject the ldquoman is the measurerdquo theory
Each person is indeed the measurer of some things Some of
them the individual gets right some of them the individual gets
wrong And in this difference lies all the difference in the world
and even outside of it

PREFACE
Inspiration is an odd beast enlightening here and deceiving
there Inspiration sometimes comes through epiphany seem-
ingly out of nowhere and resplendent with originality and beauty
Some works of great music appear in this way Friedrich
Nietzsche wrote his anti-Gospel Tus Spoke Zarathustra in a
fit of literary effusion lasting only two weeks Te result hasbaffled millions for a century
Philosophy in Seven Sentences came into being rather quickly
after a lifetime of engaging philosophy after many discussions
and arguments about philosophy after three academic degrees
in philosophy after attending (too) many conferences about phi-
losophy after grading many papers about philosophy (both
good and evil) after publishing much about philosophy after
changing some of my views on philosophy and after sometimes
questioning my own ability to do philosophy well
I was inspired by recent popular books featuring numbers
and objects in the titles such as A History of the World in
Objects by Neil MacGregor A History of the World in Six Glasses
by om Standage and Te Smithsonianrsquos History of America in Objects by Richard Kurin My object for organizing and in-
troducing philosophy was not a physical object but an object of
thought a sentence Te number seven seemed right given the

alliteration and because I was drawn to just these philosophi-
cally pregnant sentences My hope is that the book will introduce
the beginner to the craft of philosophy A seasoned reader might
find ideas worth consulting afresh or even for the first time
Philosophy is a many-splendored discipline Miniature books
such as this must fail to lasso everything and will leave many
critters hurdling about in the pasture unnamed and unattended
o talk shop Philosophy in Seven Sentences is most concerned
with epistemology (how and what we can know) and metaphysics (the study of being) ravelers through the book will also read a
bit about moral philosophy and aesthetics
Philosophers have biographies although their philosophies

bit of their stories (A few of my stories appear as well) Since
philosophers argue and agree with other philosophers I con-
sider their intellectual relationship with others in the guild par-
ticularly those philosophers whose sentences we engage Dia-
logue and debate down through the ages is the conversation of
philosophy Overhearing it may spark truth in our souls or at
least clear away some errors of thought
I do not take up theology directly but each of the seven sen-
tences bears on questions concerning God the universe andhumanity I am not sure why anyone would be interested in phi-
losophy otherwise
I have many to thank but room for only a few Jason Crowder
found references for Augustine and Pascal that eluded me (to my
shame) My colleague Sarah Geis gave excellent commentary on

Introduction
PHILOSOPHY IN ONLY
SEVEN SENTENCES
Can we tackle some of the key questions and answers in
philosophy through just seven sentences by seven famous
philosophers I wager we can so we will Many other sentencesmdash
or paragraphs or booksmdashcould have made the cut Because of
this some will argue that my selection was biased ignorant or
slanted If so let them philosophize over it After all that is the
purpose of this book to think and act philosophically
I make no claim that Philosophy in Seven Sentences is repre-
sentative of philosophy as a whole I chose these authors and
their sentences for several reasons First I was familiar with
them As I point out several times many of these ideas havedeep autobiographical significance to me Second they raise
issues pertinent to our day Tird each sentence is fairly well
known none is esoteric1 I also chose these authors because
their arguments were clear enough to be well suited to philo-
sophical analysis even on a popular level2
Some may think that popular philosophy is an oxymoron a
silly contradiction not worthy of a momentrsquos thought Phi-losophy is of course for expertsmdashthose who have accumulated
vast student-loan debts after which they have logged long and
lonely years in the classroom studying at their desks and ar-

guing with other philosophers about philosophy Tese strange
souls are abstruse esoteric recondite and many other long
pompous words not meant for the masses Philosophers write
for each other argue with each other and often flummox or bore
the hapless college students whose academic requirements put
them in their presence
And so it is for many philosophers but not for all of them At
its most ancient root philosophy was meant to initiate us into
ldquothe good liferdquo to tutor us for the ongoing experience ofknowledge and virtue Since everyone lives some kind of life
philosophy explored the mindrsquos abilities to live life in accord
with reality At best it helps scratch the itch of human exis-
tencemdashor at its worst it rubs the wound raw Even though ety-
mology (the study of word origins) may deceive it does its work
well in understanding the origin of philosophy telling us that
its two Greek parts are love ( philos) and wisdom ( sophos) Phi-
losophers may not always love wisdom but that is their disci-
plinersquos pedigree Te Hebrew Bible warns in the book of
Proverbs that both wisdom and folly call out for reflection and
allegiance Te wise are diligent in learning facing the facts in
earnest while the fool sacrifices character for ignorance and
untutored pleasure But knowledge beckons nevertheless atleast in our better moments As Aristotle wrote ldquoAll men by
nature desire to knowrdquo (We will examine this sentence shortly)
Any thinking person may join philosophyrsquos discussion which
rings down through the ages Tat is the aim of this small book
which I hope can be read profitably by both philosophical neo-
phytes and seasoned philosophers whatever their worldview
may be My aims are catholic (universal) however parochial my
selections may seem to some
Philosophy is not a closed club or a secret society Since we
all can think about ultimate questions letrsquos do it For the record

Philosophy in Only Seven Sentences
I propose that the requirements for being a philosopher (whether
good or bad major or minor professional or layperson) are a
strong and lived-out inclination to pursue truth through the rig-
orous use of human reasoning and to do so with some intel-
lectual facility But sadly even some philosophers disavow the
search for truth In Whatrsquos the Use of ruth French philosopher
Pascal Engel writes ldquoTere is no obligation to say or to be-
lieve that which is truerdquo3 If so why should we read his writings
or those of any other philosopherIs then everyone a philosopher Everyone muses a bit on
where we came from who we are and where we are going But
not all do this very well So while Johnny Rotten (b ) of the
Sex Pistols addressed some philosophical themes in his punk
rock compositions and performances one is reluctant to give
him the title of philosopher Tis is because it is a kind of merit
badge reserved for the few I was recently asked by a precocious
ten-year-old named Liam if I was a philosopher I said I was
Ten he asked ldquoWhat do you dordquo My reply was ldquoI think a lot
about argumentsrdquo We then discussed the nature of an argument
With a little coaxing he told me what an argument was giving
reasons for what you believe often in conversations with those
who believe otherwise I have recruited him for graduate studyin my program
o enjoin the discussion of philosophy I will appeal to seven
sentences all of which are short but none of which are trivial
Some are more renowned than others A few of them are famous
Tese statements are not impenetrable deceiving the unwary
inquirer with obscurity masquerading as profundity Sadly not
a few philosophers cloak their ideas with idiosyncrasies and un-
necessary jargon Not so for a Socrates or Jesus who went about
speaking the common tongue in uncommon ways to both
common and uncommon people Te public square was their

word but their words are unforgettable as we will see Teir
ideas are affirmed and denied by the simplest and most sophis-
ticated thinkers
While we cannot directly encounter the likes of Socrates or
Jesusmdashor the more bookish philosophers such as Plato Aris-
totle Augustine Descartes and kindredmdashwe can interrogate
them and investigate the perennial questions they address the
nature of truth how we gain knowledge the meaning of humanexistence death the source of morality and more In my many
years as a teacher and learner of this antique art I find to my
dismay that too many students too often give up too soon Tey
face an intellectual difficulty some demanding reading or differ-
ences of opinion and they cash in their chips despite my provo-
cations cajoling and (on occasion) anger It need not be and
should not be so S Eliot should kindle a flame in us ldquoBut our
lot crawls between dry ribs to keep our metaphysics warmrdquo4
I first read Eliotrsquos line in and never forgot it Who could
unless he or she were skimming Martin Heidegger despite his
murky prose was right in calling our lives a ldquobeing unto deathrdquo

upon it Sir when a man knows he is to be hanged in a fortnight

on all our endeavors including philosophizing Tere is like it

well now Or at least try to We can take or steal some calmly
measured time to muse on what matters most and we have

Protagoras is not a household name Google him and find out(Te first entry is not surprisingly Wikipedia) Nor do you find
many academic titles analyzing his ideas although he is often
grouped with the Sophists Tis is considered a disreputable
crowd by some wags and is even a byword ldquoYou sophistrdquo Te
charge is that Sophists cared nothing for truth but cared every-
thing about being paid to philosophize for a vested interest
More on these philosophers-for-hire later Even so this oldGreek crystallizes the thought of not a few philosophers and
nonphilosophers Our chosen sentence sums it up
Man is the measure of all things of the things which are
that they are and of things which are not that they are not6
Protagoras gives wings to an idea that many ponder try our
hardest (or not try at all) we cannot break free of ourselvesmdashour
senses our viewpoints our values even our ldquostuffrdquo Te world is
our judgment and nothing more It does not await our judgment
it is our judgment Tere is no objective truth but only various
views from various places at various times by various people
Tings are not our measure but we are the measure of them
Hence Protagoras is the spokesman for relativism sometimescalled nonrealism or perspectivism It is not just that we have no
(or limited) access to objective reality Tat is skepticism Reality
is pretty much exhausted by our perceptions and thoughts Te
real world is our world Myriads have measured Protagoras
wrong at least on this but no one in pursuit of knowledge and
wisdom can ignore him His ghost haunts us still Is there a phil-
osophical exorcist aboutOur next sentence is often heard but seldom digested I un-
failingly quote it in my first class of introduction to philosophy

students to live this waymdashfor their sakes and mine (It makes for
better papers too) Tus said Socrates the gadfly (or pain-in-
the-neck) of ancient Athens Like Protagoras we know of
Socrates through those who knew his work but unlike Pro-
tagoras we have more substantial sources particularly Plato
And Socrates is a household name Not incidentally the man
who was not an author ended up being the inspiration for the
prolific Plato who was the worldrsquos first systematic philosopher
As philosopher Alfred North Whitehead discerned ldquoTe safestgeneral characterization of the European philosophical tradition
is that it consists of a series of footnotes to Platordquo7 Te footnotes
may praise (Augustine) or blame (Aristotle) but footnotes are
everywhere as well as entire volumes
aking up Socratesrsquos philosophical challenge means exam-
ining just what his famous sentence means in itself and what it
means for us What might an examined life be given the distrac-
tions and overstimulation of postmodern times For Socrates
there is a way to calm the mind and search things out But is
there a place for Socratic dialogue today outside the Socratic
method of many law schools Further old Plato Socratesrsquos
chronicler and student may offer us wisdom pertaining to the
nagging questions of philosophy as he spurns the work of the philodoxers (lovers of opinion) and promotes the call of the phi-
losophers (lovers of wisdom) Worse yet were the misologists (one
of the Platonic corpusrsquos most winning words) those who took an
active role in hating the use of reason itself We may find some
today even in educated enclaves or even on the bestsellers lists
But one can also find Aristotle in popular bookstores always
in the philosophy section (along with less prestigious volumes
such as Led Zeppelin and Philosophy which we must pass over
without further comment) When Aristotle wrote ldquoAll men by
nature desire to knowrdquo he did not mean just the scholars or

teachers but ldquomanrdquomdashthe human race in all its circumstances and
variations Tat means every person whatever social standing
vocation or intelligence Although Aristotle was no egalitarian
(he thought that women were inferior to men and that some were
born to be slaves) he nevertheless appeals to a universal human
condition the desire to get reality right in the time that we have
Augustine the first great Christian philosopher like Socrates
before him strikes a personal note concerning getting reality
right Having examined himself and the leading philosophies ofhis day (including Plato and his footnotes) he confesses with a
cry of the heart addressed to God ldquoYou have made us for
yourself and restless is our heart until it comes to rest in yourdquo
Tis cry is not commonplace as in ldquoMy spirituality gives me
meaningrdquo It is instead the beginning of an argument told in his
autobiography In fact it may be the first autobiography on
record It is no doubt the first philosophical autobiography (if
we exclude the book of Ecclesiastes) Te irascible Jean-Jacques
Rousseau is well known for his autobiography as well but a short
book can only do so much8
Skipping madly over much philosophical history (without any
irreverence or glibness) we arrive at Reneacute Descartes the much
maligned but seldom understood ldquofather of modern philosophyrdquoDescartes was troubled by opinions without backingmdashthose
ideas about ultimate matters untethered from certainty Skep-
ticism was his foe as it is in one way or another for any philos-
opher Tis is because the question arises How do you know
what you claim to know Mere social position or historical tra-
dition will not cinch the deal for this philosopher and scientist
In our language (which itself needs interrogation) the man
ldquowanted proofrdquo While ldquoI donrsquot knowrdquo is often the most knowl-
edgeable answer it should not be the default response according
to Descartes Tis apprehension led him on a quest that began

with himself Like Augustine but in briefer scope he put this in
autobiographical form in Discourse on Method and to some
extent in Meditations on First Philosophy But Descartesrsquos quest
did not end with himself unlike so much contemporary self-
help literature He is famous for the sentence ldquoI think therefore
I amrdquo But God himself has something to do with that sentence
For Descartes there was no leap of faith in it either Reason was
the guide But how far can reason take us
A contemporary of Descartes had an idea ldquoTe heart has itsreasons that reason knows nothing ofrdquo wrote Blaise Pascal who
was the best phrasemaker of the lot of our philosophers Tis
statement is a window into a worldview Humans have the ca-
pacity to calculate and reason methodically but they may also
know some things by tracing out the contours and resources of
ldquothe heartrdquomdashanother organ of knowledge Philosophers study
many thinkers but few come to love few of them (My graduate
seminar on Kantrsquos Critique of Pure Reason was well worth it but
was no love affair) Pascal on the contrary is much loved by many
He is so loved that people even love things he never actually said
such as ldquoTere is a God-shaped vacuum that only God can fillrdquo
But this paraphrase is not far off the mark though it should be
placed within a larger perspective of Pascalrsquos philosophyTe French polymathrsquos philosophy is far more fascinating than
the CliffsNotes version allows Pascal did not put faith in place
of reason and he was not a one-trick philosopher (Pascalrsquos
wager) Slander and libel have fouled the air about him ob-
scuring his sophisticated treatment of the cost-benefit sense of
believing in religion or not Yet he was neither knave nor poser
Te founder of probability theory and the inventor of the first
working calculating machine had reasons for faith Like Des-
cartes he was bugged by skepticism and like Descartes he ap-
pealed to human nature as a place to start the discussion

Philosophy in Only Seven Sentences
Our last sentence is not as well known as the previous ones
but it opens a door of inquiry for us
Te greatest hazard of all losing onersquos self can occur very
quietly in the world as if it were nothing at all
It was penned by an idiosyncratic and famously melancholy
Dane named Soslashren Kierkegaard a philosopher intensely inter-
ested in the self in relation to ultimate reality Tis should sound
familiar since all philosophers have expressed this interest inone way or another But Kierkegaardrsquos way was in a sense as
much psychological as philosophical He intrepidly limned the
inner workings of the self of consciousness in philosophical
categories Like Pascal Kierkegaard wanted to strip away
through existential analysis the layers and dynamics of the self
that keep reality at bay Unlike Pascal and the other philosophers
he was more interested in the analysis of the self than presentingit with arguments for an abstract objective reality Tis may
sound a bit unphilosophical but it is not But that takes time to
tease out properly as I hope you will see
Our seven sentences may be viewed as several doors into
worlds previously unknown Or they may be our irritants to
prod us to move away from facile factoidsmdashldquoDo your own thingrdquoldquoFollow your blissrdquo ldquoKeep Calm and Carry Onrdquomdashto more so-
bering reflections9 Perhaps the sentences are bridges to other
lands of thought Tese philosophical sentences do not sum the
thought of any of the philosophers for these thinkers are far too
deep for that Nor do the seven sentences aim to summarize the
history of philosophy Tat would be a pompous and laughable
claim Some things cannot be put into a nutshell including thenutshell itself But I claim that philosophical activity can be
sparked by just seven sterling sentencesmdashand who knows where
it might lead

Greeks could do philosophy Te basic questions of exis-
tence have never been far from the human mind but the
ancient Greeks excelled at this and their musingsmdashsome frag-
mentary or secondhandmdashhave been preserved in written texts
However much philosophy occurred in exclusively oral cultures
the Greeks valued writing in addition to oral memory and tra-
dition Socrates you remember wrote nothing but generated a vast literature though his dialogues A lesser-known figure who
came after him did write a few things and his famous adage is
worth considering
Protagoras (fifth century BC) is not to be confused with
like-sounding ancient Greek thinkers named Pythagoras or
Parmenides who along with others were pre-Socratic thinkers
(Tis shows the significance of Socrates since philosophy isdated with respect to his life) Tese thinkers are worth inter-
rogating as well and I studied them with profit in a year-long
course in ancient philosophy forty years ago Protagoras

stands out to us though because of his adage about absolute
assessment
Man is the measure of all things of the things which are
that they are and of things which are not that they are not1
His claim is not simply that people measure thingsmdashsuch as
character chariots boats and fishmdashbut that each human is the
measure Each person is the assessment or judgment What
could this mean No person is a slide ruler or scale or Geigercounter although we avail ourselves of such things
W I M
We tend to think that people use a standard of measurement
outside of themselves Even inadequate and one-dimensional
measures such as onersquos IQ score are not determined by how we
feel about themmdashand Mensa is very picky about thisOn the other hand Protagoras has Shakespearersquos Hamlet on
his side at least concerning morality ldquoFor there is nothing either
good or bad but thinking makes it sordquo2 Tat is morals do not
have objective standing rather they are judged differently by
different people Tis quote is from a discussion about Denmark
which Hamlet unlike his interlocutor Rosencrantz said was ldquoaprisonrdquo If Hamlet is right then both Hamlet and Rosencrantz
are right about Denmark
What then was Protagorasrsquos point (Wersquoll put serious Shake-
spearian interpretation aside) o find out we need to take a step
back into the Greek philosophical scene and not rush to
judgmentmdashor rush to endorsement either Protagoras would ap-
prove of this deliberationProtagoras was considered the chief of the Sophists intellec-
tuals who were paid to defend the views of their sponsors Tey
were accomplished orators as well as thinkers Originally the

term sophist meant something like our ldquoprofessorrdquo but later a
Sophist was deemed a hired gun a philosopher for hire and one
having no principles of his own Teir arguments supposedly
were merely the instruments of the will of their bosses One may
argue over the virtues of the Sophists but it is certainly not true
that being paid for philosophizing necessarily disqualifies the
employeersquos arguments On the other hand if we think of a
Sophist as something like a political speech writer or the like
our judgment will change Whatever the intellectual rectitudeof Protagoras he was a perpetual lecturer who articulated and
debated ideas in the marketplace a marketplace of ideas that yet

Protagoras was one of a spirited group of fastidious thinkers
who tired or at least grew skeptical of Greek mythology with
its pantheon of gods Yes the stories of the gods were often riv-
eting and worth repeating A recent volume by Luc Ferry is
called Te Wisdom of the Myths How Greek Mythology Can
Change Your Life3 Tere was always a moral to the story Her-
cules the last son of Zeus was a dashing and dramatic character
who started as a mighty mortal and became a god upon deathAlthough a bit impetuous and lacking in sobriety he plays well
as a hero Zeus himself is the apotheosis of power but acts
largely without moral authority Even the might of Zeus does not
support the idea that ldquomight makes rightrdquo since might may make
for divine mischief My point is not to survey or psychoanalyze
the denizens of Greek mythology but to make a general point
Mythologies may inspire and guide to some extent our relation
to the hard facts of family life death and sexuality (and some of
the gods tended to be naughty in this way)
Nevertheless the problem with Greek mythology (or any

mythology Eastern or Western) is simply that it is mythology it
is neither history nor clearly articulated philosophy In too many
ways the gods despite their thespian reacutesumeacutes and magical
powers were not much more than semi- glorified mortals Tis
was the objection of a growing group of Greeks who were mere
mortalsmdashmortals with meaning metaphysics and morality on
their minds And what might the mind do when free to explore
life and its questions apart from the venerable stories of Greek
fascination It might philosophize and so it didProtagoras and his cohorts quested for explanations of a more
abstract but also compelling sort than the old tales could afford
Tey sought principles to explain facts in a universal and logi-
cally coherent manner o be a little unfair to the mythologies
consider the tooth fairy She adds some magical benevolence to
the loss and placement of a baby tooth for children but the fairy
story adds nothing about the nature of benevolence the signifi-
cance of teeth or the significance of the humans who grow and
lose these teeth whether through development (teething) or
decay (the toothless)
Tus to give one example Tales of Miletus tried to find a
cosmic commonality to all things He divined it as water Yes
water which was more than rain oceans lakes and puddles Itwas everywhere so perhaps it was the root and branch of every-
thing Water or moisture in general lives in the clouds in plants
in animals (aquatic land or amphibious) and in thirsty mortals
It condenses and evaporates but never leaves the planet Con-
sidering the presence and power of water Tales extrapolated
that water was more than one more thing on earth however
necessary for life It was rather the unifying principle for exis-
tence Whatever we think of Tales his thinking is not absurd
and it indicates a thirst for philosophical explanation as opposed
to mythological meanderings At least he was trying

But it is Protagoras who calls for our attention Instead of ar-guing for something at the heart of everything (water for Tales)
a principle found in nature Protagoras moved back from nature
to the self After all skeptics had questioned mere mortalsrsquo
ability to know with any confidence what is out there inde-
pendent of themselves Te jaundiced eye sees things differently
from the nonjaundiced eye Children perceive entities invisible
to adults Adults sometimes hallucinatemdashbut perhaps they areseeing what most miss One woman feels cold in a room of degF
and another feels hot Age alters hearing seeing memory and
may jangle judgments Te upshot is that we cannot find a place
to stand to see the world as it is We are simply ill-equipped to
do so Objective truth what is independent of our perceptions
endlessly and mercilessly eludes us
We will return to skepticism when discussing Descartes and
Pascal but Protagoras was not a skeptic He did not withhold
judgments about facts in themselves because we do not have the
ability to know them While recognizing that the skeptics had
dethroned our intellectual confidence in capturing objective re-
ality his point of departure was this we do know our own view-
points judgments and beliefs Tat is we measure things theydo not measure themselves So I take most of Francis Baconrsquos
paintings to be ugly and thus unattractive I am repulsed Tis is
the end of the story or my story Tis is my measurement You
on the contrary may find delight in Baconrsquos tortured figures and
color schemes Tat is your measurement and the end of your
story
Now reconsider the skeptical point made earlier One person
can deem the room cold and another hot Te skeptic might say
we cannot know then what the room is given the variability in
perception But Protagoras claims that the room is hot for person

A and not hot for person B Tere is no contradiction since we
are considering individual perceptions Tere are two measure-
ments each of which is valid Tus Bacon is barbaric to me and
beautiful to youmdashand that is the level best we can do Or perhaps
I will come to adore Baconrsquos paintings and heap scorn on my
former judgment If so then that is my measurement
Tis is rather attractive at first blush After all there is no
dispute in matters of taste or to be more snobby De gustibus
non est disputandum Te avant-garde saxophone playing ofPeter Broumltzmann can send me into the upper reaches of aes-
thetic delight while sending others scurrying from the room
while covering their ears But Protagoras took this insight far
beyond artistic judgments Notice the reference range (or extent)
of Protagorasrsquos statement ldquoMan is the measure of all thingsrdquomdash
matters of taste as well as matters of fact matters of principle
and matters of matter Nothing is excluded
Let us follow this out As we think it through the old Greek
will sound much like modern man If Protagoras is right then
there is no disputing matters of morality either Man is the
measure of what is right and what is wrong what is virtuous and
what is vicious what should be loved and what should be hatedmdash
just as Hamlet claimed oday this thinking is usually put in thelanguage of choice instead of measurement but the idea is the
same If you chose to do X that choice is the end of the matter
Or to suit Protagoras if you measure X as worth doing then it
is worth doing Tis is true whether X refers to sailing stealing
or stampeding cattle in the direction of a Cub Scout outing
But we might say ldquoWho is to judgerdquo Who of us can stand
above him- or herself and others and become objective Yes we
recoil from some ideasmdashsuch as torturing the innocent merely
for pleasure or female genital mutilation But what does that tell
us about reality if there really is such a thing as reality Te claim

that ldquoman is the measure of all thingsrdquo is an all-encompassing
judgment itself Te answer to ldquoWho is to judgerdquo is that we are

boldness and daring ldquothe strength of characterrdquo to throw

often hand out this Bundy quotation but without identifying the
speaker I then ask them to write a paragraph on whether they
agree with its basic idea Most students approve of the unknown
authorrsquos sentiments I then reveal that this statement was the
philosophy of one of the most infamous serial killers in American
historymdashthe philosophy that allowed and even impelled hisegregious crimes Next I ask them to reconsider their judg-
ments Te results are usually mixed but the majority of stu-
dents show dismay and surprise that they were in agreement
with a view that justified serial rape and murder
Yet today a television seriesmdasha comedy nonethelessmdashis about
a serial killer named Dexter o top that off there is even a book
called Dexter and Philosophy Mind over Spatter Can such atroc-
ities be lifted so easily from bloody reality and into a neutral
realm of entertainment For many it can and so they seem to
agree with Protagoras at least implicitly there is no objective
good and evil nothing sacrosanct or sacrilegious nothing above
us and nothing beneath us It is all merely neutral and we make
the callmdashon everything ldquoMan is the measure of all thingsrdquoSo then what does this sentence tell us about philosophy and
what philosophy means to us Philosophical claims if clearly
articulated give us significant matters to ponder logically and

existentially Tey often capture some truth and so seduce us
on this basis But a statement cannot be true unless it accords
with the way the world in fact is and the way we in fact are Pro-
tagoras does capture some truths about perspective For ex-
ample my tastes in food determine how I measure the goodness
of the food I am the measure of that at least It matters nothing
whether a connoisseur thinks me an ignoramus I can only
measure it by what I experience at the moment In that way I am
the measure but am I the expert Am I the knowerTere is a strange implication for Protagorasrsquos view In the
Teaetetus Protagoras even states that error is impossible5 Al-
though he was a teacher he cannot by his own lights teach
anyone o this Socrates inquires
If whatever the individual judges by means of perception is
true for him if no man can assess anotherrsquos experiencebetter than he or can claim authority to examine another
manrsquos judgment and see if it be right or wrong if as we
have repeatedly said only the individual himself can judge
of his own world and what he judges is always true and
correct how could it ever be my friend that Protagoras
was a wise man so wise as to think himself fit to be the
teacher of other men and worth large fees while we in
comparison with him the ignorant ones needed to go and
sit at his feetmdashwe who are ourselves each the measure of
his own wisdom6
Te gadfly of Athens made short work of a self-refuting phi-
losophy Tis should whet our appetite for the next chapter in
which Socrates takes the starring role

human languages For example the general concept of cat may
be written in Chinese or in English Since each language uses
different symbols for writing its graphic inscription for cat will
differ Tis is true for voicing the word cat as well Trough a
long messy process not instigated by any central planning each
culture selects its own conventions of communication Are not
these two systems of writing measuring reality in very different
ways In point of fact they are not
Both kinds of writing systems (as well as other means ofcommunication) make claims about a reality that are outside
of the systems themselves and outside of the individuals who
use the pictographic or ideographic methods We tacitly saw
this earlier But in both cases a cat is invoked there is a single
referent Te differences in linguistic custom are not differ-
ences in content A cat is a cat in whatever language and it will
not bark however it may be measured Moreover while it may
be vexing in places one can translate a book from English to
Chinese Not everything is lost in translation in fact more is
found than is lost ranslators need have no fear of losing their
livelihood
Staying on matters of taste for a moment (and not morality
for now) are all people equally skilled in measurement Tepoet and literary critic S Eliot advocated the cultivation of
ldquoeducated tasterdquo Consider your preferences in music and
reading when you were quite young Tey are likely not the
same as when you became an adult You may still enjoy and
laugh at nursery rhymes but your tastes have expanded Yes
you still love Winnie the Pooh (and I mean the original Pooh
not the Walt Disney version) but you understand and appre-
ciate it more deeply now If so (and substitute your own ex-
amples here if needed) your tastes have at least changed and
have likely improved with age Your earlier judgments were

Protagoras
likely age appropriate but they were limited and (not unex-
pectedly) childish Te apostle Paul notes this in a well-known
turn of phrase ldquoWhen I was a child I talked like a child I
thought like a child I reasoned like a child When I became a
man I put the ways of childhood behind merdquo ( Corinthians
see also Hebrews -)
Furthermore the very notion of improvement or progress
(not merely some change in quality) requires and assumes an
objective standard by which to measure improvement (or de-cline) If a baseball batter hits in and in he
has improved based on the best possible average of Tere
is a measurement and it is not the perception of the batter that
determines this measurement Tis is the case in the arts as well
Few knowledgeable about jazz would dispute that John Col-
tranersquos saxophone work improved during his tenure with pianist
Telonious Monkrsquos quartet or that it developed further in Col-
trane own ldquoclassic quartetrdquo (ndash)7 Here the assessment is
not quantitative or statistical but qualitative One might object
that this is a purely subjective judgment (such as whether one
feels hot or not) which is relative to the person hearing Who is
to judge Te answer is straightforward the one whose expe-
rience knowledge and wisdom merit approval Although manydrink wine there are few expert wine tasters A student of mine
is so adept at this art that he can tell what part of the country a
wine came from Not having developed this advanced degree of
skill this is foreign to me However I had no inclination to say
that my judgment on wine is as accurate as Markrsquos Along these
lines I was once embarrassed when one of my students told me
that the wine I was enjoying was ldquothe Kenny G of winesrdquo Tis as
jazz aficionados know was not a compliment about the wine or
about my taste for wine
Artistic judgments involve much more than my quick treatment

I have not even given clear aesthetic criteria8 My point is that
beauty is not only in the eye of the beholder If not we are haunted
by objective realities which pay no heed to mere preference

But Herodotus may yet rescue Protagoras In his History the
ancient historian notes that Darius a king of ancient Persia (who
was a kind of premodern anthropologist because of his study of
cultural differences) called together some Greeks and askedthem what it would take to cannibalize their dead fathers Te
Greeks needed no time to ponder the proposition since nothing
would move them to such odious paternal desecration Teir
practice was cremation this alone would honor their dead Ten
Darius summoned several Callatians (from India) to join the
Greeks and asked them what would make them cremate their
deceased fathers Te Callatians were as horrified as the Greeks
had been and told Darius to not discuss such atrocities
Had Protagoras heard this he would likely applaud having
found more evidence for his outlook But not all applause is
earned While the Greeks and Callatians observed fundamen-
tally different funeral rites both cultures honored the dead Tat
is only particular practicesmdashnot just any old or new thingmdashwere esteemed right and good in the treatment of corpses and
these practices were not norms for the treatment of the living
In other words death was set apart as uniquely meaningful and
thus required that the living treat the dead with ritual respect
Tus Greeks and Callatians agreed on a deep principle of hon-
oring the dead Tey disagreed on the rule that stems from that
principle In no sense then does the example of cultural rela-
tivity disprove moral agreement across cultures since there was
deep agreement between the cultures C S Lewis makes just
this point in Mere Christianity

Protagoras
I know that some people say the idea of a Law of Nature or
decent behaviour known to all men is unsound because
different civilisations and different ages have had quite dif-
ferent moralities
But this is not true Tere have been differences between
their moralities but these have never amounted to any-
thing like a total difference If anyone will take the trouble
to compare the moral teaching of say the ancient Egyp-
tians Babylonians Hindus Chinese Greeks and Romanswhat will really strike him will be how very like they are to
each other and to our own9
Te case against Protagoras comes down to this If we want to
learn anything if we want to improve as human beings if we
want to condemn the ed Bundys of the world if we want any
kind of educated taste if we desire to understand and honorhumanity then we must reject the ldquoman is the measurerdquo theory
Each person is indeed the measurer of some things Some of
them the individual gets right some of them the individual gets
wrong And in this difference lies all the difference in the world
and even outside of it

PREFACE
Inspiration is an odd beast enlightening here and deceiving
there Inspiration sometimes comes through epiphany seem-
ingly out of nowhere and resplendent with originality and beauty
Some works of great music appear in this way Friedrich
Nietzsche wrote his anti-Gospel Tus Spoke Zarathustra in a
fit of literary effusion lasting only two weeks Te result hasbaffled millions for a century
Philosophy in Seven Sentences came into being rather quickly
after a lifetime of engaging philosophy after many discussions
and arguments about philosophy after three academic degrees
in philosophy after attending (too) many conferences about phi-
losophy after grading many papers about philosophy (both
good and evil) after publishing much about philosophy after
changing some of my views on philosophy and after sometimes
questioning my own ability to do philosophy well
I was inspired by recent popular books featuring numbers
and objects in the titles such as A History of the World in
Objects by Neil MacGregor A History of the World in Six Glasses
by om Standage and Te Smithsonianrsquos History of America in Objects by Richard Kurin My object for organizing and in-
troducing philosophy was not a physical object but an object of
thought a sentence Te number seven seemed right given the

alliteration and because I was drawn to just these philosophi-
cally pregnant sentences My hope is that the book will introduce
the beginner to the craft of philosophy A seasoned reader might
find ideas worth consulting afresh or even for the first time
Philosophy is a many-splendored discipline Miniature books
such as this must fail to lasso everything and will leave many
critters hurdling about in the pasture unnamed and unattended
o talk shop Philosophy in Seven Sentences is most concerned
with epistemology (how and what we can know) and metaphysics (the study of being) ravelers through the book will also read a
bit about moral philosophy and aesthetics
Philosophers have biographies although their philosophies
are not limited to their biographies So each chapter includes a
bit of their stories (A few of my stories appear as well) Since
philosophers argue and agree with other philosophers I con-
sider their intellectual relationship with others in the guild par-
ticularly those philosophers whose sentences we engage Dia-
logue and debate down through the ages is the conversation of
philosophy Overhearing it may spark truth in our souls or at
least clear away some errors of thought
I do not take up theology directly but each of the seven sen-
tences bears on questions concerning God the universe andhumanity I am not sure why anyone would be interested in phi-
losophy otherwise
I have many to thank but room for only a few Jason Crowder
found references for Augustine and Pascal that eluded me (to my
shame) My colleague Sarah Geis gave excellent commentary on
Descartes Elizabeth Johnson contributed some dandy editing
Rebecca Merrill Groothuis prayed for this book project as she
has for all my other ones Tanks also to the administration of
Denver Seminary for granting me a sabbatical during which
much of this work was done

Introduction
PHILOSOPHY IN ONLY
SEVEN SENTENCES
Can we tackle some of the key questions and answers in
philosophy through just seven sentences by seven famous
philosophers I wager we can so we will Many other sentencesmdash
or paragraphs or booksmdashcould have made the cut Because of
this some will argue that my selection was biased ignorant or
slanted If so let them philosophize over it After all that is the
purpose of this book to think and act philosophically
I make no claim that Philosophy in Seven Sentences is repre-
sentative of philosophy as a whole I chose these authors and
their sentences for several reasons First I was familiar with
them As I point out several times many of these ideas havedeep autobiographical significance to me Second they raise
issues pertinent to our day Tird each sentence is fairly well
known none is esoteric1 I also chose these authors because
their arguments were clear enough to be well suited to philo-
sophical analysis even on a popular level2
Some may think that popular philosophy is an oxymoron a
silly contradiction not worthy of a momentrsquos thought Phi-losophy is of course for expertsmdashthose who have accumulated
vast student-loan debts after which they have logged long and
lonely years in the classroom studying at their desks and ar-

guing with other philosophers about philosophy Tese strange
souls are abstruse esoteric recondite and many other long
pompous words not meant for the masses Philosophers write
for each other argue with each other and often flummox or bore
the hapless college students whose academic requirements put
them in their presence
And so it is for many philosophers but not for all of them At
its most ancient root philosophy was meant to initiate us into
ldquothe good liferdquo to tutor us for the ongoing experience ofknowledge and virtue Since everyone lives some kind of life
philosophy explored the mindrsquos abilities to live life in accord
with reality At best it helps scratch the itch of human exis-
tencemdashor at its worst it rubs the wound raw Even though ety-
mology (the study of word origins) may deceive it does its work
well in understanding the origin of philosophy telling us that
its two Greek parts are love ( philos) and wisdom ( sophos) Phi-
losophers may not always love wisdom but that is their disci-
plinersquos pedigree Te Hebrew Bible warns in the book of
Proverbs that both wisdom and folly call out for reflection and
allegiance Te wise are diligent in learning facing the facts in
earnest while the fool sacrifices character for ignorance and
untutored pleasure But knowledge beckons nevertheless atleast in our better moments As Aristotle wrote ldquoAll men by
nature desire to knowrdquo (We will examine this sentence shortly)
Any thinking person may join philosophyrsquos discussion which
rings down through the ages Tat is the aim of this small book
which I hope can be read profitably by both philosophical neo-
phytes and seasoned philosophers whatever their worldview
may be My aims are catholic (universal) however parochial my
selections may seem to some
Philosophy is not a closed club or a secret society Since we
all can think about ultimate questions letrsquos do it For the record

Philosophy in Only Seven Sentences
I propose that the requirements for being a philosopher (whether
good or bad major or minor professional or layperson) are a
strong and lived-out inclination to pursue truth through the rig-
orous use of human reasoning and to do so with some intel-
lectual facility But sadly even some philosophers disavow the
search for truth In Whatrsquos the Use of ruth French philosopher
Pascal Engel writes ldquoTere is no obligation to say or to be-
lieve that which is truerdquo3 If so why should we read his writings
or those of any other philosopherIs then everyone a philosopher Everyone muses a bit on
where we came from who we are and where we are going But
not all do this very well So while Johnny Rotten (b ) of the
Sex Pistols addressed some philosophical themes in his punk
rock compositions and performances one is reluctant to give
him the title of philosopher Tis is because it is a kind of merit
badge reserved for the few I was recently asked by a precocious
ten-year-old named Liam if I was a philosopher I said I was
Ten he asked ldquoWhat do you dordquo My reply was ldquoI think a lot
about argumentsrdquo We then discussed the nature of an argument
With a little coaxing he told me what an argument was giving
reasons for what you believe often in conversations with those
who believe otherwise I have recruited him for graduate studyin my program
o enjoin the discussion of philosophy I will appeal to seven
sentences all of which are short but none of which are trivial
Some are more renowned than others A few of them are famous
Tese statements are not impenetrable deceiving the unwary
inquirer with obscurity masquerading as profundity Sadly not
a few philosophers cloak their ideas with idiosyncrasies and un-
necessary jargon Not so for a Socrates or Jesus who went about
speaking the common tongue in uncommon ways to both
common and uncommon people Te public square was their

classroom and all comers were their students Neither wrote a
word but their words are unforgettable as we will see Teir
ideas are affirmed and denied by the simplest and most sophis-
ticated thinkers
While we cannot directly encounter the likes of Socrates or
Jesusmdashor the more bookish philosophers such as Plato Aris-
totle Augustine Descartes and kindredmdashwe can interrogate
them and investigate the perennial questions they address the
nature of truth how we gain knowledge the meaning of humanexistence death the source of morality and more In my many
years as a teacher and learner of this antique art I find to my
dismay that too many students too often give up too soon Tey
face an intellectual difficulty some demanding reading or differ-
ences of opinion and they cash in their chips despite my provo-
cations cajoling and (on occasion) anger It need not be and
should not be so S Eliot should kindle a flame in us ldquoBut our
lot crawls between dry ribs to keep our metaphysics warmrdquo4
I first read Eliotrsquos line in and never forgot it Who could
unless he or she were skimming Martin Heidegger despite his
murky prose was right in calling our lives a ldquobeing unto deathrdquo
because our eventual demisemdashgradual or instantmdashbrackets
everything we think or do or hope ldquoNo one gets out of here aliverdquois no tired clicheacute unhappily Samuel Johnson put it well ldquoDepend
upon it Sir when a man knows he is to be hanged in a fortnight
it concentrates his mind wonderfullyrdquo5 Our mortality sets limits
on all our endeavors including philosophizing Tere is like it
or not a flashing stop sign ahead on the road So why not think
well now Or at least try to We can take or steal some calmly
measured time to muse on what matters most and we have
some guidesmdashepitomized by their sentencesmdashto light the way
or at least to rebuke our intellectual laziness Let me introduce
them in historical order

Protagoras is not a household name Google him and find out(Te first entry is not surprisingly Wikipedia) Nor do you find
many academic titles analyzing his ideas although he is often
grouped with the Sophists Tis is considered a disreputable
crowd by some wags and is even a byword ldquoYou sophistrdquo Te
charge is that Sophists cared nothing for truth but cared every-
thing about being paid to philosophize for a vested interest
More on these philosophers-for-hire later Even so this oldGreek crystallizes the thought of not a few philosophers and
nonphilosophers Our chosen sentence sums it up
Man is the measure of all things of the things which are
that they are and of things which are not that they are not6
Protagoras gives wings to an idea that many ponder try our
hardest (or not try at all) we cannot break free of ourselvesmdashour
senses our viewpoints our values even our ldquostuffrdquo Te world is
our judgment and nothing more It does not await our judgment
it is our judgment Tere is no objective truth but only various
views from various places at various times by various people
Tings are not our measure but we are the measure of them
Hence Protagoras is the spokesman for relativism sometimescalled nonrealism or perspectivism It is not just that we have no
(or limited) access to objective reality Tat is skepticism Reality
is pretty much exhausted by our perceptions and thoughts Te
real world is our world Myriads have measured Protagoras
wrong at least on this but no one in pursuit of knowledge and
wisdom can ignore him His ghost haunts us still Is there a phil-
osophical exorcist aboutOur next sentence is often heard but seldom digested I un-
failingly quote it in my first class of introduction to philosophy

students to live this waymdashfor their sakes and mine (It makes for
better papers too) Tus said Socrates the gadfly (or pain-in-
the-neck) of ancient Athens Like Protagoras we know of
Socrates through those who knew his work but unlike Pro-
tagoras we have more substantial sources particularly Plato
And Socrates is a household name Not incidentally the man
who was not an author ended up being the inspiration for the
prolific Plato who was the worldrsquos first systematic philosopher
As philosopher Alfred North Whitehead discerned ldquoTe safestgeneral characterization of the European philosophical tradition
is that it consists of a series of footnotes to Platordquo7 Te footnotes
may praise (Augustine) or blame (Aristotle) but footnotes are
everywhere as well as entire volumes

means for us What might an examined life be given the distrac-
tions and overstimulation of postmodern times For Socrates
there is a way to calm the mind and search things out But is
there a place for Socratic dialogue today outside the Socratic
method of many law schools Further old Plato Socratesrsquos
chronicler and student may offer us wisdom pertaining to the
nagging questions of philosophy as he spurns the work of the philodoxers (lovers of opinion) and promotes the call of the phi-
losophers (lovers of wisdom) Worse yet were the misologists (one
of the Platonic corpusrsquos most winning words) those who took an
active role in hating the use of reason itself We may find some
today even in educated enclaves or even on the bestsellers lists
But one can also find Aristotle in popular bookstores always
in the philosophy section (along with less prestigious volumes
such as Led Zeppelin and Philosophy which we must pass over
without further comment) When Aristotle wrote ldquoAll men by
nature desire to knowrdquo he did not mean just the scholars or

teachers but ldquomanrdquomdashthe human race in all its circumstances and
variations Tat means every person whatever social standing
vocation or intelligence Although Aristotle was no egalitarian
(he thought that women were inferior to men and that some were
born to be slaves) he nevertheless appeals to a universal human
condition the desire to get reality right in the time that we have
Augustine the first great Christian philosopher like Socrates
before him strikes a personal note concerning getting reality
right Having examined himself and the leading philosophies ofhis day (including Plato and his footnotes) he confesses with a
cry of the heart addressed to God ldquoYou have made us for
yourself and restless is our heart until it comes to rest in yourdquo
Tis cry is not commonplace as in ldquoMy spirituality gives me
meaningrdquo It is instead the beginning of an argument told in his
autobiography In fact it may be the first autobiography on
record It is no doubt the first philosophical autobiography (if
we exclude the book of Ecclesiastes) Te irascible Jean-Jacques
Rousseau is well known for his autobiography as well but a short
book can only do so much8
Skipping madly over much philosophical history (without any
irreverence or glibness) we arrive at Reneacute Descartes the much
maligned but seldom understood ldquofather of modern philosophyrdquoDescartes was troubled by opinions without backingmdashthose
ideas about ultimate matters untethered from certainty Skep-
ticism was his foe as it is in one way or another for any philos-
opher Tis is because the question arises How do you know
what you claim to know Mere social position or historical tra-
dition will not cinch the deal for this philosopher and scientist
In our language (which itself needs interrogation) the man
ldquowanted proofrdquo While ldquoI donrsquot knowrdquo is often the most knowl-
edgeable answer it should not be the default response according
to Descartes Tis apprehension led him on a quest that began

with himself Like Augustine but in briefer scope he put this in
autobiographical form in Discourse on Method and to some
extent in Meditations on First Philosophy But Descartesrsquos quest
did not end with himself unlike so much contemporary self-
help literature He is famous for the sentence ldquoI think therefore
I amrdquo But God himself has something to do with that sentence
For Descartes there was no leap of faith in it either Reason was
the guide But how far can reason take us
A contemporary of Descartes had an idea ldquoTe heart has itsreasons that reason knows nothing ofrdquo wrote Blaise Pascal who
was the best phrasemaker of the lot of our philosophers Tis
statement is a window into a worldview Humans have the ca-
pacity to calculate and reason methodically but they may also
know some things by tracing out the contours and resources of
ldquothe heartrdquomdashanother organ of knowledge Philosophers study
many thinkers but few come to love few of them (My graduate
seminar on Kantrsquos Critique of Pure Reason was well worth it but
was no love affair) Pascal on the contrary is much loved by many
He is so loved that people even love things he never actually said
such as ldquoTere is a God-shaped vacuum that only God can fillrdquo
But this paraphrase is not far off the mark though it should be
placed within a larger perspective of Pascalrsquos philosophyTe French polymathrsquos philosophy is far more fascinating than
the CliffsNotes version allows Pascal did not put faith in place
of reason and he was not a one-trick philosopher (Pascalrsquos
wager) Slander and libel have fouled the air about him ob-
scuring his sophisticated treatment of the cost-benefit sense of
believing in religion or not Yet he was neither knave nor poser
Te founder of probability theory and the inventor of the first
working calculating machine had reasons for faith Like Des-
cartes he was bugged by skepticism and like Descartes he ap-
pealed to human nature as a place to start the discussion

Philosophy in Only Seven Sentences
Our last sentence is not as well known as the previous ones
but it opens a door of inquiry for us
Te greatest hazard of all losing onersquos self can occur very
quietly in the world as if it were nothing at all
It was penned by an idiosyncratic and famously melancholy
Dane named Soslashren Kierkegaard a philosopher intensely inter-
ested in the self in relation to ultimate reality Tis should sound
familiar since all philosophers have expressed this interest inone way or another But Kierkegaardrsquos way was in a sense as
much psychological as philosophical He intrepidly limned the
inner workings of the self of consciousness in philosophical
categories Like Pascal Kierkegaard wanted to strip away
through existential analysis the layers and dynamics of the self
that keep reality at bay Unlike Pascal and the other philosophers
he was more interested in the analysis of the self than presentingit with arguments for an abstract objective reality Tis may
sound a bit unphilosophical but it is not But that takes time to
tease out properly as I hope you will see
Our seven sentences may be viewed as several doors into
worlds previously unknown Or they may be our irritants to
prod us to move away from facile factoidsmdashldquoDo your own thingrdquoldquoFollow your blissrdquo ldquoKeep Calm and Carry Onrdquomdashto more so-
bering reflections9 Perhaps the sentences are bridges to other
lands of thought Tese philosophical sentences do not sum the
thought of any of the philosophers for these thinkers are far too
deep for that Nor do the seven sentences aim to summarize the
history of philosophy Tat would be a pompous and laughable
claim Some things cannot be put into a nutshell including thenutshell itself But I claim that philosophical activity can be
sparked by just seven sterling sentencesmdashand who knows where
it might lead

PROTAGORAS
Man is the measure of all things
P
Greeks could do philosophy Te basic questions of exis-
tence have never been far from the human mind but the
ancient Greeks excelled at this and their musingsmdashsome frag-
mentary or secondhandmdashhave been preserved in written texts
However much philosophy occurred in exclusively oral cultures
the Greeks valued writing in addition to oral memory and tra-
dition Socrates you remember wrote nothing but generated a vast literature though his dialogues A lesser-known figure who
came after him did write a few things and his famous adage is
worth considering
Protagoras (fifth century BC) is not to be confused with
like-sounding ancient Greek thinkers named Pythagoras or
Parmenides who along with others were pre-Socratic thinkers
(Tis shows the significance of Socrates since philosophy isdated with respect to his life) Tese thinkers are worth inter-
rogating as well and I studied them with profit in a year-long
course in ancient philosophy forty years ago Protagoras

stands out to us though because of his adage about absolute
assessment
Man is the measure of all things of the things which are
that they are and of things which are not that they are not1
His claim is not simply that people measure thingsmdashsuch as
character chariots boats and fishmdashbut that each human is the
measure Each person is the assessment or judgment What
could this mean No person is a slide ruler or scale or Geigercounter although we avail ourselves of such things
W I M
We tend to think that people use a standard of measurement
outside of themselves Even inadequate and one-dimensional
measures such as onersquos IQ score are not determined by how we
feel about themmdashand Mensa is very picky about thisOn the other hand Protagoras has Shakespearersquos Hamlet on
his side at least concerning morality ldquoFor there is nothing either
good or bad but thinking makes it sordquo2 Tat is morals do not
have objective standing rather they are judged differently by
different people Tis quote is from a discussion about Denmark
which Hamlet unlike his interlocutor Rosencrantz said was ldquoaprisonrdquo If Hamlet is right then both Hamlet and Rosencrantz
are right about Denmark
What then was Protagorasrsquos point (Wersquoll put serious Shake-
spearian interpretation aside) o find out we need to take a step
back into the Greek philosophical scene and not rush to
judgmentmdashor rush to endorsement either Protagoras would ap-
prove of this deliberationProtagoras was considered the chief of the Sophists intellec-
tuals who were paid to defend the views of their sponsors Tey
were accomplished orators as well as thinkers Originally the

term sophist meant something like our ldquoprofessorrdquo but later a
Sophist was deemed a hired gun a philosopher for hire and one
having no principles of his own Teir arguments supposedly
were merely the instruments of the will of their bosses One may
argue over the virtues of the Sophists but it is certainly not true
that being paid for philosophizing necessarily disqualifies the
employeersquos arguments On the other hand if we think of a
Sophist as something like a political speech writer or the like
our judgment will change Whatever the intellectual rectitudeof Protagoras he was a perpetual lecturer who articulated and
debated ideas in the marketplace a marketplace of ideas that yet
exists We may join in the discussion

Protagoras was one of a spirited group of fastidious thinkers
who tired or at least grew skeptical of Greek mythology with
its pantheon of gods Yes the stories of the gods were often riv-
eting and worth repeating A recent volume by Luc Ferry is
called Te Wisdom of the Myths How Greek Mythology Can
Change Your Life3 Tere was always a moral to the story Her-
cules the last son of Zeus was a dashing and dramatic character
who started as a mighty mortal and became a god upon deathAlthough a bit impetuous and lacking in sobriety he plays well
as a hero Zeus himself is the apotheosis of power but acts
largely without moral authority Even the might of Zeus does not
support the idea that ldquomight makes rightrdquo since might may make
for divine mischief My point is not to survey or psychoanalyze
the denizens of Greek mythology but to make a general point
Mythologies may inspire and guide to some extent our relation
to the hard facts of family life death and sexuality (and some of
the gods tended to be naughty in this way)
Nevertheless the problem with Greek mythology (or any

mythology Eastern or Western) is simply that it is mythology it
is neither history nor clearly articulated philosophy In too many
ways the gods despite their thespian reacutesumeacutes and magical
powers were not much more than semi- glorified mortals Tis
was the objection of a growing group of Greeks who were mere
mortalsmdashmortals with meaning metaphysics and morality on
their minds And what might the mind do when free to explore
life and its questions apart from the venerable stories of Greek
fascination It might philosophize and so it didProtagoras and his cohorts quested for explanations of a more
abstract but also compelling sort than the old tales could afford
Tey sought principles to explain facts in a universal and logi-
cally coherent manner o be a little unfair to the mythologies
consider the tooth fairy She adds some magical benevolence to
the loss and placement of a baby tooth for children but the fairy
story adds nothing about the nature of benevolence the signifi-
cance of teeth or the significance of the humans who grow and
lose these teeth whether through development (teething) or
decay (the toothless)
Tus to give one example Tales of Miletus tried to find a
cosmic commonality to all things He divined it as water Yes
water which was more than rain oceans lakes and puddles Itwas everywhere so perhaps it was the root and branch of every-
thing Water or moisture in general lives in the clouds in plants
in animals (aquatic land or amphibious) and in thirsty mortals
It condenses and evaporates but never leaves the planet Con-
sidering the presence and power of water Tales extrapolated
that water was more than one more thing on earth however
necessary for life It was rather the unifying principle for exis-
tence Whatever we think of Tales his thinking is not absurd
and it indicates a thirst for philosophical explanation as opposed
to mythological meanderings At least he was trying

Protagoras

But it is Protagoras who calls for our attention Instead of ar-guing for something at the heart of everything (water for Tales)
a principle found in nature Protagoras moved back from nature
to the self After all skeptics had questioned mere mortalsrsquo
ability to know with any confidence what is out there inde-
pendent of themselves Te jaundiced eye sees things differently
from the nonjaundiced eye Children perceive entities invisible
to adults Adults sometimes hallucinatemdashbut perhaps they areseeing what most miss One woman feels cold in a room of degF
and another feels hot Age alters hearing seeing memory and
may jangle judgments Te upshot is that we cannot find a place
to stand to see the world as it is We are simply ill-equipped to
do so Objective truth what is independent of our perceptions
endlessly and mercilessly eludes us
We will return to skepticism when discussing Descartes and
Pascal but Protagoras was not a skeptic He did not withhold
judgments about facts in themselves because we do not have the
ability to know them While recognizing that the skeptics had
dethroned our intellectual confidence in capturing objective re-
ality his point of departure was this we do know our own view-
points judgments and beliefs Tat is we measure things theydo not measure themselves So I take most of Francis Baconrsquos
paintings to be ugly and thus unattractive I am repulsed Tis is
the end of the story or my story Tis is my measurement You
on the contrary may find delight in Baconrsquos tortured figures and
color schemes Tat is your measurement and the end of your
story
Now reconsider the skeptical point made earlier One person
can deem the room cold and another hot Te skeptic might say
we cannot know then what the room is given the variability in
perception But Protagoras claims that the room is hot for person

A and not hot for person B Tere is no contradiction since we
are considering individual perceptions Tere are two measure-
ments each of which is valid Tus Bacon is barbaric to me and
beautiful to youmdashand that is the level best we can do Or perhaps
I will come to adore Baconrsquos paintings and heap scorn on my
former judgment If so then that is my measurement
Tis is rather attractive at first blush After all there is no
dispute in matters of taste or to be more snobby De gustibus
non est disputandum Te avant-garde saxophone playing ofPeter Broumltzmann can send me into the upper reaches of aes-
thetic delight while sending others scurrying from the room
while covering their ears But Protagoras took this insight far
beyond artistic judgments Notice the reference range (or extent)
of Protagorasrsquos statement ldquoMan is the measure of all thingsrdquomdash
matters of taste as well as matters of fact matters of principle
and matters of matter Nothing is excluded
Let us follow this out As we think it through the old Greek
will sound much like modern man If Protagoras is right then
there is no disputing matters of morality either Man is the
measure of what is right and what is wrong what is virtuous and
what is vicious what should be loved and what should be hatedmdash
just as Hamlet claimed oday this thinking is usually put in thelanguage of choice instead of measurement but the idea is the
same If you chose to do X that choice is the end of the matter
Or to suit Protagoras if you measure X as worth doing then it
is worth doing Tis is true whether X refers to sailing stealing
or stampeding cattle in the direction of a Cub Scout outing
But we might say ldquoWho is to judgerdquo Who of us can stand
above him- or herself and others and become objective Yes we
recoil from some ideasmdashsuch as torturing the innocent merely
for pleasure or female genital mutilation But what does that tell
us about reality if there really is such a thing as reality Te claim

that ldquoman is the measure of all thingsrdquo is an all-encompassing
judgment itself Te answer to ldquoWho is to judgerdquo is that we are
the measure of all things Tat is there is nothing outside of
human judgment by which it might be judged But why would

Moral Philosophy Bundy said
I learned that all moral judgments are ldquovalue judgmentsrdquo
that all value judgments are subjective and that none can
be proved to be either ldquorightrdquo or ldquowrongrdquo I even read some-where that the Chief Justice of the United States had written
that the American Constitution expressed nothing more
than collective value judgments Believe it or not I figured
out for myselfmdashwhat apparently the Chief Justice couldnrsquot
figure out for himselfmdashthat if the rationality of one value
judgment was zero multiplying it by millions would not
make it one whit more rational Nor is there any ldquoreasonrdquo
to obey the law for anyone like myself who has the
boldness and daring ldquothe strength of characterrdquo to throw
off its shackles
I discovered that to become truly free truly unfettered
I had to become truly uninhibited And I quickly discovered
that the greatest obstacle to my freedom the greatest blockand limitation to it consists in the insupportable ldquovalue

When teaching ethics to undergraduates at a secular school I
often hand out this Bundy quotation but without identifying the

agree with its basic idea Most students approve of the unknown

philosophy of one of the most infamous serial killers in American
historymdashthe philosophy that allowed and even impelled hisegregious crimes Next I ask them to reconsider their judg-

dents show dismay and surprise that they were in agreement

us and nothing beneath us It is all merely neutral and we make

existentially Tey often capture some truth and so seduce us
on this basis But a statement cannot be true unless it accords
with the way the world in fact is and the way we in fact are Pro-
tagoras does capture some truths about perspective For ex-
ample my tastes in food determine how I measure the goodness
of the food I am the measure of that at least It matters nothing
whether a connoisseur thinks me an ignoramus I can only
measure it by what I experience at the moment In that way I am
the measure but am I the expert Am I the knowerTere is a strange implication for Protagorasrsquos view In the
Teaetetus Protagoras even states that error is impossible5 Al-
though he was a teacher he cannot by his own lights teach
anyone o this Socrates inquires
If whatever the individual judges by means of perception is
true for him if no man can assess anotherrsquos experiencebetter than he or can claim authority to examine another
manrsquos judgment and see if it be right or wrong if as we
have repeatedly said only the individual himself can judge
of his own world and what he judges is always true and
correct how could it ever be my friend that Protagoras
was a wise man so wise as to think himself fit to be the
teacher of other men and worth large fees while we in
comparison with him the ignorant ones needed to go and
sit at his feetmdashwe who are ourselves each the measure of
his own wisdom6

human languages For example the general concept of cat may
be written in Chinese or in English Since each language uses
different symbols for writing its graphic inscription for cat will
differ Tis is true for voicing the word cat as well Trough a
long messy process not instigated by any central planning each
culture selects its own conventions of communication Are not
these two systems of writing measuring reality in very different
ways In point of fact they are not
Both kinds of writing systems (as well as other means ofcommunication) make claims about a reality that are outside
of the systems themselves and outside of the individuals who
use the pictographic or ideographic methods We tacitly saw
this earlier But in both cases a cat is invoked there is a single
referent Te differences in linguistic custom are not differ-
ences in content A cat is a cat in whatever language and it will
not bark however it may be measured Moreover while it may
be vexing in places one can translate a book from English to
Chinese Not everything is lost in translation in fact more is
found than is lost ranslators need have no fear of losing their
livelihood
Staying on matters of taste for a moment (and not morality

same as when you became an adult You may still enjoy and

pectedly) childish Te apostle Paul notes this in a well-known
turn of phrase ldquoWhen I was a child I talked like a child I
thought like a child I reasoned like a child When I became a

Furthermore the very notion of improvement or progress
(not merely some change in quality) requires and assumes an
objective standard by which to measure improvement (or de-cline) If a baseball batter hits in and in he
has improved based on the best possible average of Tere
is a measurement and it is not the perception of the batter that
determines this measurement Tis is the case in the arts as well
Few knowledgeable about jazz would dispute that John Col-
tranersquos saxophone work improved during his tenure with pianist
Telonious Monkrsquos quartet or that it developed further in Col-
trane own ldquoclassic quartetrdquo (ndash)7 Here the assessment is
not quantitative or statistical but qualitative One might object
that this is a purely subjective judgment (such as whether one
feels hot or not) which is relative to the person hearing Who is
to judge Te answer is straightforward the one whose expe-
rience knowledge and wisdom merit approval Although manydrink wine there are few expert wine tasters A student of mine
is so adept at this art that he can tell what part of the country a
wine came from Not having developed this advanced degree of
skill this is foreign to me However I had no inclination to say
that my judgment on wine is as accurate as Markrsquos Along these
lines I was once embarrassed when one of my students told me
that the wine I was enjoying was ldquothe Kenny G of winesrdquo Tis as
jazz aficionados know was not a compliment about the wine or
about my taste for wine

But Herodotus may yet rescue Protagoras In his History the
ancient historian notes that Darius a king of ancient Persia (who
was a kind of premodern anthropologist because of his study of
cultural differences) called together some Greeks and askedthem what it would take to cannibalize their dead fathers Te
Greeks needed no time to ponder the proposition since nothing
would move them to such odious paternal desecration Teir
practice was cremation this alone would honor their dead Ten
Darius summoned several Callatians (from India) to join the
Greeks and asked them what would make them cremate their
deceased fathers Te Callatians were as horrified as the Greeks
had been and told Darius to not discuss such atrocities
Had Protagoras heard this he would likely applaud having
found more evidence for his outlook But not all applause is
earned While the Greeks and Callatians observed fundamen-
tally different funeral rites both cultures honored the dead Tat
is only particular practicesmdashnot just any old or new thingmdashwere esteemed right and good in the treatment of corpses and
these practices were not norms for the treatment of the living
In other words death was set apart as uniquely meaningful and
thus required that the living treat the dead with ritual respect
Tus Greeks and Callatians agreed on a deep principle of hon-
oring the dead Tey disagreed on the rule that stems from that
principle In no sense then does the example of cultural rela-
tivity disprove moral agreement across cultures since there was
deep agreement between the cultures C S Lewis makes just
this point in Mere Christianity

Protagoras
I know that some people say the idea of a Law of Nature or
decent behaviour known to all men is unsound because
different civilisations and different ages have had quite dif-
ferent moralities
But this is not true Tere have been differences between
their moralities but these have never amounted to any-
thing like a total difference If anyone will take the trouble
to compare the moral teaching of say the ancient Egyp-
tians Babylonians Hindus Chinese Greeks and Romanswhat will really strike him will be how very like they are to
each other and to our own9
Te case against Protagoras comes down to this If we want to
learn anything if we want to improve as human beings if we
want to condemn the ed Bundys of the world if we want any
kind of educated taste if we desire to understand and honorhumanity then we must reject the ldquoman is the measurerdquo theory
Each person is indeed the measurer of some things Some of
them the individual gets right some of them the individual gets
wrong And in this difference lies all the difference in the world
and even outside of it

PREFACE
Inspiration is an odd beast enlightening here and deceiving
there Inspiration sometimes comes through epiphany seem-
ingly out of nowhere and resplendent with originality and beauty
Some works of great music appear in this way Friedrich
Nietzsche wrote his anti-Gospel Tus Spoke Zarathustra in a
fit of literary effusion lasting only two weeks Te result hasbaffled millions for a century
Philosophy in Seven Sentences came into being rather quickly
after a lifetime of engaging philosophy after many discussions
and arguments about philosophy after three academic degrees
in philosophy after attending (too) many conferences about phi-
losophy after grading many papers about philosophy (both
good and evil) after publishing much about philosophy after
changing some of my views on philosophy and after sometimes
questioning my own ability to do philosophy well
I was inspired by recent popular books featuring numbers
and objects in the titles such as A History of the World in
Objects by Neil MacGregor A History of the World in Six Glasses
by om Standage and Te Smithsonianrsquos History of America in Objects by Richard Kurin My object for organizing and in-
troducing philosophy was not a physical object but an object of
thought a sentence Te number seven seemed right given the

alliteration and because I was drawn to just these philosophi-
cally pregnant sentences My hope is that the book will introduce
the beginner to the craft of philosophy A seasoned reader might
find ideas worth consulting afresh or even for the first time
Philosophy is a many-splendored discipline Miniature books
such as this must fail to lasso everything and will leave many
critters hurdling about in the pasture unnamed and unattended
o talk shop Philosophy in Seven Sentences is most concerned
with epistemology (how and what we can know) and metaphysics (the study of being) ravelers through the book will also read a
bit about moral philosophy and aesthetics
Philosophers have biographies although their philosophies
are not limited to their biographies So each chapter includes a
bit of their stories (A few of my stories appear as well) Since
philosophers argue and agree with other philosophers I con-
sider their intellectual relationship with others in the guild par-
ticularly those philosophers whose sentences we engage Dia-
logue and debate down through the ages is the conversation of
philosophy Overhearing it may spark truth in our souls or at
least clear away some errors of thought
I do not take up theology directly but each of the seven sen-
tences bears on questions concerning God the universe andhumanity I am not sure why anyone would be interested in phi-
losophy otherwise
I have many to thank but room for only a few Jason Crowder
found references for Augustine and Pascal that eluded me (to my
shame) My colleague Sarah Geis gave excellent commentary on
Descartes Elizabeth Johnson contributed some dandy editing
Rebecca Merrill Groothuis prayed for this book project as she
has for all my other ones Tanks also to the administration of
Denver Seminary for granting me a sabbatical during which
much of this work was done

Introduction
PHILOSOPHY IN ONLY
SEVEN SENTENCES
Can we tackle some of the key questions and answers in
philosophy through just seven sentences by seven famous
philosophers I wager we can so we will Many other sentencesmdash
or paragraphs or booksmdashcould have made the cut Because of
this some will argue that my selection was biased ignorant or
slanted If so let them philosophize over it After all that is the
purpose of this book to think and act philosophically
I make no claim that Philosophy in Seven Sentences is repre-
sentative of philosophy as a whole I chose these authors and
their sentences for several reasons First I was familiar with
them As I point out several times many of these ideas havedeep autobiographical significance to me Second they raise
issues pertinent to our day Tird each sentence is fairly well
known none is esoteric1 I also chose these authors because
their arguments were clear enough to be well suited to philo-
sophical analysis even on a popular level2
Some may think that popular philosophy is an oxymoron a
silly contradiction not worthy of a momentrsquos thought Phi-losophy is of course for expertsmdashthose who have accumulated
vast student-loan debts after which they have logged long and
lonely years in the classroom studying at their desks and ar-

guing with other philosophers about philosophy Tese strange
souls are abstruse esoteric recondite and many other long
pompous words not meant for the masses Philosophers write
for each other argue with each other and often flummox or bore
the hapless college students whose academic requirements put
them in their presence
And so it is for many philosophers but not for all of them At
its most ancient root philosophy was meant to initiate us into
ldquothe good liferdquo to tutor us for the ongoing experience ofknowledge and virtue Since everyone lives some kind of life
philosophy explored the mindrsquos abilities to live life in accord
with reality At best it helps scratch the itch of human exis-
tencemdashor at its worst it rubs the wound raw Even though ety-
mology (the study of word origins) may deceive it does its work
well in understanding the origin of philosophy telling us that
its two Greek parts are love ( philos) and wisdom ( sophos) Phi-
losophers may not always love wisdom but that is their disci-
plinersquos pedigree Te Hebrew Bible warns in the book of
Proverbs that both wisdom and folly call out for reflection and
allegiance Te wise are diligent in learning facing the facts in
earnest while the fool sacrifices character for ignorance and
untutored pleasure But knowledge beckons nevertheless atleast in our better moments As Aristotle wrote ldquoAll men by
nature desire to knowrdquo (We will examine this sentence shortly)
Any thinking person may join philosophyrsquos discussion which
rings down through the ages Tat is the aim of this small book
which I hope can be read profitably by both philosophical neo-
phytes and seasoned philosophers whatever their worldview
may be My aims are catholic (universal) however parochial my
selections may seem to some
Philosophy is not a closed club or a secret society Since we
all can think about ultimate questions letrsquos do it For the record

Philosophy in Only Seven Sentences
I propose that the requirements for being a philosopher (whether
good or bad major or minor professional or layperson) are a
strong and lived-out inclination to pursue truth through the rig-
orous use of human reasoning and to do so with some intel-
lectual facility But sadly even some philosophers disavow the
search for truth In Whatrsquos the Use of ruth French philosopher
Pascal Engel writes ldquoTere is no obligation to say or to be-
lieve that which is truerdquo3 If so why should we read his writings
or those of any other philosopherIs then everyone a philosopher Everyone muses a bit on
where we came from who we are and where we are going But
not all do this very well So while Johnny Rotten (b ) of the
Sex Pistols addressed some philosophical themes in his punk
rock compositions and performances one is reluctant to give
him the title of philosopher Tis is because it is a kind of merit
badge reserved for the few I was recently asked by a precocious
ten-year-old named Liam if I was a philosopher I said I was
Ten he asked ldquoWhat do you dordquo My reply was ldquoI think a lot
about argumentsrdquo We then discussed the nature of an argument
With a little coaxing he told me what an argument was giving
reasons for what you believe often in conversations with those
who believe otherwise I have recruited him for graduate studyin my program
o enjoin the discussion of philosophy I will appeal to seven
sentences all of which are short but none of which are trivial
Some are more renowned than others A few of them are famous
Tese statements are not impenetrable deceiving the unwary
inquirer with obscurity masquerading as profundity Sadly not
a few philosophers cloak their ideas with idiosyncrasies and un-
necessary jargon Not so for a Socrates or Jesus who went about
speaking the common tongue in uncommon ways to both
common and uncommon people Te public square was their

classroom and all comers were their students Neither wrote a
word but their words are unforgettable as we will see Teir
ideas are affirmed and denied by the simplest and most sophis-
ticated thinkers
While we cannot directly encounter the likes of Socrates or
Jesusmdashor the more bookish philosophers such as Plato Aris-
totle Augustine Descartes and kindredmdashwe can interrogate
them and investigate the perennial questions they address the
nature of truth how we gain knowledge the meaning of humanexistence death the source of morality and more In my many
years as a teacher and learner of this antique art I find to my
dismay that too many students too often give up too soon Tey
face an intellectual difficulty some demanding reading or differ-
ences of opinion and they cash in their chips despite my provo-
cations cajoling and (on occasion) anger It need not be and
should not be so S Eliot should kindle a flame in us ldquoBut our
lot crawls between dry ribs to keep our metaphysics warmrdquo4
I first read Eliotrsquos line in and never forgot it Who could
unless he or she were skimming Martin Heidegger despite his
murky prose was right in calling our lives a ldquobeing unto deathrdquo
because our eventual demisemdashgradual or instantmdashbrackets
everything we think or do or hope ldquoNo one gets out of here aliverdquois no tired clicheacute unhappily Samuel Johnson put it well ldquoDepend
upon it Sir when a man knows he is to be hanged in a fortnight
it concentrates his mind wonderfullyrdquo5 Our mortality sets limits
on all our endeavors including philosophizing Tere is like it
or not a flashing stop sign ahead on the road So why not think
well now Or at least try to We can take or steal some calmly
measured time to muse on what matters most and we have
some guidesmdashepitomized by their sentencesmdashto light the way
or at least to rebuke our intellectual laziness Let me introduce
them in historical order

Protagoras is not a household name Google him and find out(Te first entry is not surprisingly Wikipedia) Nor do you find
many academic titles analyzing his ideas although he is often
grouped with the Sophists Tis is considered a disreputable
crowd by some wags and is even a byword ldquoYou sophistrdquo Te
charge is that Sophists cared nothing for truth but cared every-
thing about being paid to philosophize for a vested interest
More on these philosophers-for-hire later Even so this oldGreek crystallizes the thought of not a few philosophers and
nonphilosophers Our chosen sentence sums it up
Man is the measure of all things of the things which are
that they are and of things which are not that they are not6
Protagoras gives wings to an idea that many ponder try our
hardest (or not try at all) we cannot break free of ourselvesmdashour
senses our viewpoints our values even our ldquostuffrdquo Te world is
our judgment and nothing more It does not await our judgment
it is our judgment Tere is no objective truth but only various
views from various places at various times by various people
Tings are not our measure but we are the measure of them
Hence Protagoras is the spokesman for relativism sometimescalled nonrealism or perspectivism It is not just that we have no
(or limited) access to objective reality Tat is skepticism Reality
is pretty much exhausted by our perceptions and thoughts Te
real world is our world Myriads have measured Protagoras
wrong at least on this but no one in pursuit of knowledge and
wisdom can ignore him His ghost haunts us still Is there a phil-
osophical exorcist aboutOur next sentence is often heard but seldom digested I un-
failingly quote it in my first class of introduction to philosophy

students to live this waymdashfor their sakes and mine (It makes for
better papers too) Tus said Socrates the gadfly (or pain-in-
the-neck) of ancient Athens Like Protagoras we know of
Socrates through those who knew his work but unlike Pro-
tagoras we have more substantial sources particularly Plato
And Socrates is a household name Not incidentally the man
who was not an author ended up being the inspiration for the
prolific Plato who was the worldrsquos first systematic philosopher
As philosopher Alfred North Whitehead discerned ldquoTe safestgeneral characterization of the European philosophical tradition
is that it consists of a series of footnotes to Platordquo7 Te footnotes
may praise (Augustine) or blame (Aristotle) but footnotes are
everywhere as well as entire volumes
aking up Socratesrsquos philosophical challenge means exam-
ining just what his famous sentence means in itself and what it
means for us What might an examined life be given the distrac-
tions and overstimulation of postmodern times For Socrates
there is a way to calm the mind and search things out But is
there a place for Socratic dialogue today outside the Socratic
method of many law schools Further old Plato Socratesrsquos
chronicler and student may offer us wisdom pertaining to the
nagging questions of philosophy as he spurns the work of the philodoxers (lovers of opinion) and promotes the call of the phi-
losophers (lovers of wisdom) Worse yet were the misologists (one
of the Platonic corpusrsquos most winning words) those who took an
active role in hating the use of reason itself We may find some
today even in educated enclaves or even on the bestsellers lists
But one can also find Aristotle in popular bookstores always
in the philosophy section (along with less prestigious volumes
such as Led Zeppelin and Philosophy which we must pass over
without further comment) When Aristotle wrote ldquoAll men by
nature desire to knowrdquo he did not mean just the scholars or

teachers but ldquomanrdquomdashthe human race in all its circumstances and
variations Tat means every person whatever social standing
vocation or intelligence Although Aristotle was no egalitarian
(he thought that women were inferior to men and that some were
born to be slaves) he nevertheless appeals to a universal human
condition the desire to get reality right in the time that we have
Augustine the first great Christian philosopher like Socrates
before him strikes a personal note concerning getting reality
right Having examined himself and the leading philosophies ofhis day (including Plato and his footnotes) he confesses with a
cry of the heart addressed to God ldquoYou have made us for
yourself and restless is our heart until it comes to rest in yourdquo
Tis cry is not commonplace as in ldquoMy spirituality gives me
meaningrdquo It is instead the beginning of an argument told in his
autobiography In fact it may be the first autobiography on
record It is no doubt the first philosophical autobiography (if
we exclude the book of Ecclesiastes) Te irascible Jean-Jacques
Rousseau is well known for his autobiography as well but a short
book can only do so much8
Skipping madly over much philosophical history (without any
irreverence or glibness) we arrive at Reneacute Descartes the much
maligned but seldom understood ldquofather of modern philosophyrdquoDescartes was troubled by opinions without backingmdashthose
ideas about ultimate matters untethered from certainty Skep-
ticism was his foe as it is in one way or another for any philos-
opher Tis is because the question arises How do you know
what you claim to know Mere social position or historical tra-
dition will not cinch the deal for this philosopher and scientist
In our language (which itself needs interrogation) the man
ldquowanted proofrdquo While ldquoI donrsquot knowrdquo is often the most knowl-
edgeable answer it should not be the default response according
to Descartes Tis apprehension led him on a quest that began

with himself Like Augustine but in briefer scope he put this in
autobiographical form in Discourse on Method and to some
extent in Meditations on First Philosophy But Descartesrsquos quest
did not end with himself unlike so much contemporary self-
help literature He is famous for the sentence ldquoI think therefore
I amrdquo But God himself has something to do with that sentence
For Descartes there was no leap of faith in it either Reason was
the guide But how far can reason take us
A contemporary of Descartes had an idea ldquoTe heart has itsreasons that reason knows nothing ofrdquo wrote Blaise Pascal who
was the best phrasemaker of the lot of our philosophers Tis
statement is a window into a worldview Humans have the ca-
pacity to calculate and reason methodically but they may also
know some things by tracing out the contours and resources of
ldquothe heartrdquomdashanother organ of knowledge Philosophers study
many thinkers but few come to love few of them (My graduate
seminar on Kantrsquos Critique of Pure Reason was well worth it but
was no love affair) Pascal on the contrary is much loved by many
He is so loved that people even love things he never actually said
such as ldquoTere is a God-shaped vacuum that only God can fillrdquo
But this paraphrase is not far off the mark though it should be
placed within a larger perspective of Pascalrsquos philosophyTe French polymathrsquos philosophy is far more fascinating than
the CliffsNotes version allows Pascal did not put faith in place
of reason and he was not a one-trick philosopher (Pascalrsquos
wager) Slander and libel have fouled the air about him ob-
scuring his sophisticated treatment of the cost-benefit sense of
believing in religion or not Yet he was neither knave nor poser
Te founder of probability theory and the inventor of the first
working calculating machine had reasons for faith Like Des-
cartes he was bugged by skepticism and like Descartes he ap-
pealed to human nature as a place to start the discussion

Philosophy in Only Seven Sentences
Our last sentence is not as well known as the previous ones
but it opens a door of inquiry for us
Te greatest hazard of all losing onersquos self can occur very
quietly in the world as if it were nothing at all
It was penned by an idiosyncratic and famously melancholy
Dane named Soslashren Kierkegaard a philosopher intensely inter-
ested in the self in relation to ultimate reality Tis should sound
familiar since all philosophers have expressed this interest inone way or another But Kierkegaardrsquos way was in a sense as
much psychological as philosophical He intrepidly limned the
inner workings of the self of consciousness in philosophical
categories Like Pascal Kierkegaard wanted to strip away
through existential analysis the layers and dynamics of the self
that keep reality at bay Unlike Pascal and the other philosophers
he was more interested in the analysis of the self than presentingit with arguments for an abstract objective reality Tis may
sound a bit unphilosophical but it is not But that takes time to
tease out properly as I hope you will see
Our seven sentences may be viewed as several doors into
worlds previously unknown Or they may be our irritants to
prod us to move away from facile factoidsmdashldquoDo your own thingrdquoldquoFollow your blissrdquo ldquoKeep Calm and Carry Onrdquomdashto more so-
bering reflections9 Perhaps the sentences are bridges to other
lands of thought Tese philosophical sentences do not sum the
thought of any of the philosophers for these thinkers are far too
deep for that Nor do the seven sentences aim to summarize the
history of philosophy Tat would be a pompous and laughable
claim Some things cannot be put into a nutshell including thenutshell itself But I claim that philosophical activity can be
sparked by just seven sterling sentencesmdashand who knows where
it might lead

Man is the measure of all things
P
Greeks could do philosophy Te basic questions of exis-
tence have never been far from the human mind but the
ancient Greeks excelled at this and their musingsmdashsome frag-
mentary or secondhandmdashhave been preserved in written texts
However much philosophy occurred in exclusively oral cultures
the Greeks valued writing in addition to oral memory and tra-
dition Socrates you remember wrote nothing but generated a vast literature though his dialogues A lesser-known figure who
came after him did write a few things and his famous adage is
worth considering
Protagoras (fifth century BC) is not to be confused with
like-sounding ancient Greek thinkers named Pythagoras or
Parmenides who along with others were pre-Socratic thinkers
(Tis shows the significance of Socrates since philosophy isdated with respect to his life) Tese thinkers are worth inter-
rogating as well and I studied them with profit in a year-long
course in ancient philosophy forty years ago Protagoras

stands out to us though because of his adage about absolute
assessment
Man is the measure of all things of the things which are
that they are and of things which are not that they are not1
His claim is not simply that people measure thingsmdashsuch as
character chariots boats and fishmdashbut that each human is the
measure Each person is the assessment or judgment What
could this mean No person is a slide ruler or scale or Geigercounter although we avail ourselves of such things
W I M
We tend to think that people use a standard of measurement
outside of themselves Even inadequate and one-dimensional
measures such as onersquos IQ score are not determined by how we
feel about themmdashand Mensa is very picky about thisOn the other hand Protagoras has Shakespearersquos Hamlet on
his side at least concerning morality ldquoFor there is nothing either
good or bad but thinking makes it sordquo2 Tat is morals do not
have objective standing rather they are judged differently by
different people Tis quote is from a discussion about Denmark
which Hamlet unlike his interlocutor Rosencrantz said was ldquoaprisonrdquo If Hamlet is right then both Hamlet and Rosencrantz
are right about Denmark
What then was Protagorasrsquos point (Wersquoll put serious Shake-
spearian interpretation aside) o find out we need to take a step
back into the Greek philosophical scene and not rush to
judgmentmdashor rush to endorsement either Protagoras would ap-
prove of this deliberationProtagoras was considered the chief of the Sophists intellec-
tuals who were paid to defend the views of their sponsors Tey
were accomplished orators as well as thinkers Originally the

term sophist meant something like our ldquoprofessorrdquo but later a
Sophist was deemed a hired gun a philosopher for hire and one
having no principles of his own Teir arguments supposedly
were merely the instruments of the will of their bosses One may
argue over the virtues of the Sophists but it is certainly not true
that being paid for philosophizing necessarily disqualifies the
employeersquos arguments On the other hand if we think of a
Sophist as something like a political speech writer or the like
our judgment will change Whatever the intellectual rectitudeof Protagoras he was a perpetual lecturer who articulated and
debated ideas in the marketplace a marketplace of ideas that yet
exists We may join in the discussion
M P
Protagoras was one of a spirited group of fastidious thinkers
who tired or at least grew skeptical of Greek mythology with
its pantheon of gods Yes the stories of the gods were often riv-
eting and worth repeating A recent volume by Luc Ferry is
called Te Wisdom of the Myths How Greek Mythology Can
Change Your Life3 Tere was always a moral to the story Her-
cules the last son of Zeus was a dashing and dramatic character
who started as a mighty mortal and became a god upon deathAlthough a bit impetuous and lacking in sobriety he plays well
as a hero Zeus himself is the apotheosis of power but acts
largely without moral authority Even the might of Zeus does not
support the idea that ldquomight makes rightrdquo since might may make
for divine mischief My point is not to survey or psychoanalyze
the denizens of Greek mythology but to make a general point

mythology Eastern or Western) is simply that it is mythology it
is neither history nor clearly articulated philosophy In too many
ways the gods despite their thespian reacutesumeacutes and magical
powers were not much more than semi- glorified mortals Tis
was the objection of a growing group of Greeks who were mere
mortalsmdashmortals with meaning metaphysics and morality on
their minds And what might the mind do when free to explore
life and its questions apart from the venerable stories of Greek
fascination It might philosophize and so it didProtagoras and his cohorts quested for explanations of a more
abstract but also compelling sort than the old tales could afford
Tey sought principles to explain facts in a universal and logi-
cally coherent manner o be a little unfair to the mythologies
consider the tooth fairy She adds some magical benevolence to
the loss and placement of a baby tooth for children but the fairy
story adds nothing about the nature of benevolence the signifi-
cance of teeth or the significance of the humans who grow and
lose these teeth whether through development (teething) or
decay (the toothless)
Tus to give one example Tales of Miletus tried to find a
cosmic commonality to all things He divined it as water Yes
water which was more than rain oceans lakes and puddles Itwas everywhere so perhaps it was the root and branch of every-
thing Water or moisture in general lives in the clouds in plants
in animals (aquatic land or amphibious) and in thirsty mortals
It condenses and evaporates but never leaves the planet Con-
sidering the presence and power of water Tales extrapolated
that water was more than one more thing on earth however
necessary for life It was rather the unifying principle for exis-
tence Whatever we think of Tales his thinking is not absurd
and it indicates a thirst for philosophical explanation as opposed
to mythological meanderings At least he was trying

Protagoras

But it is Protagoras who calls for our attention Instead of ar-guing for something at the heart of everything (water for Tales)
a principle found in nature Protagoras moved back from nature
to the self After all skeptics had questioned mere mortalsrsquo
ability to know with any confidence what is out there inde-
pendent of themselves Te jaundiced eye sees things differently
from the nonjaundiced eye Children perceive entities invisible
to adults Adults sometimes hallucinatemdashbut perhaps they areseeing what most miss One woman feels cold in a room of degF
and another feels hot Age alters hearing seeing memory and
may jangle judgments Te upshot is that we cannot find a place
to stand to see the world as it is We are simply ill-equipped to
do so Objective truth what is independent of our perceptions
endlessly and mercilessly eludes us
We will return to skepticism when discussing Descartes and
Pascal but Protagoras was not a skeptic He did not withhold
judgments about facts in themselves because we do not have the
ability to know them While recognizing that the skeptics had
dethroned our intellectual confidence in capturing objective re-
ality his point of departure was this we do know our own view-
points judgments and beliefs Tat is we measure things theydo not measure themselves So I take most of Francis Baconrsquos
paintings to be ugly and thus unattractive I am repulsed Tis is
the end of the story or my story Tis is my measurement You
on the contrary may find delight in Baconrsquos tortured figures and
color schemes Tat is your measurement and the end of your
story
Now reconsider the skeptical point made earlier One person
can deem the room cold and another hot Te skeptic might say
we cannot know then what the room is given the variability in
perception But Protagoras claims that the room is hot for person

A and not hot for person B Tere is no contradiction since we
are considering individual perceptions Tere are two measure-
ments each of which is valid Tus Bacon is barbaric to me and
beautiful to youmdashand that is the level best we can do Or perhaps
I will come to adore Baconrsquos paintings and heap scorn on my
former judgment If so then that is my measurement
Tis is rather attractive at first blush After all there is no
dispute in matters of taste or to be more snobby De gustibus
non est disputandum Te avant-garde saxophone playing ofPeter Broumltzmann can send me into the upper reaches of aes-
thetic delight while sending others scurrying from the room
while covering their ears But Protagoras took this insight far
beyond artistic judgments Notice the reference range (or extent)
of Protagorasrsquos statement ldquoMan is the measure of all thingsrdquomdash
matters of taste as well as matters of fact matters of principle
and matters of matter Nothing is excluded
Let us follow this out As we think it through the old Greek
will sound much like modern man If Protagoras is right then
there is no disputing matters of morality either Man is the
measure of what is right and what is wrong what is virtuous and
what is vicious what should be loved and what should be hatedmdash
just as Hamlet claimed oday this thinking is usually put in thelanguage of choice instead of measurement but the idea is the
same If you chose to do X that choice is the end of the matter
Or to suit Protagoras if you measure X as worth doing then it
is worth doing Tis is true whether X refers to sailing stealing
or stampeding cattle in the direction of a Cub Scout outing
But we might say ldquoWho is to judgerdquo Who of us can stand
above him- or herself and others and become objective Yes we
recoil from some ideasmdashsuch as torturing the innocent merely
for pleasure or female genital mutilation But what does that tell
us about reality if there really is such a thing as reality Te claim

that ldquoman is the measure of all thingsrdquo is an all-encompassing
judgment itself Te answer to ldquoWho is to judgerdquo is that we are
the measure of all things Tat is there is nothing outside of
human judgment by which it might be judged But why would

Besides being a serial killer ed Bundy was a philosophical
thinker of the Protagorean type Remarkably his philosophy wascaught on tape before he raped and killed a young woman She
was one of dozens of his prey As reported in Louis Pojmanrsquos text
Moral Philosophy Bundy said
I learned that all moral judgments are ldquovalue judgmentsrdquo
that all value judgments are subjective and that none can
be proved to be either ldquorightrdquo or ldquowrongrdquo I even read some-where that the Chief Justice of the United States had written
that the American Constitution expressed nothing more
than collective value judgments Believe it or not I figured
out for myselfmdashwhat apparently the Chief Justice couldnrsquot
figure out for himselfmdashthat if the rationality of one value
judgment was zero multiplying it by millions would not
make it one whit more rational Nor is there any ldquoreasonrdquo
to obey the law for anyone like myself who has the
boldness and daring ldquothe strength of characterrdquo to throw
off its shackles
I discovered that to become truly free truly unfettered
I had to become truly uninhibited And I quickly discovered
that the greatest obstacle to my freedom the greatest blockand limitation to it consists in the insupportable ldquovalue

steer Is your life more to you than a hogrsquos life to a hog
Why should I be willing to sacrifice my pleasure more for
the one than for the other Surely you would not in this
age of scientific enlightenment declare that God or nature
has marked some pleasures as ldquomoralrdquo or ldquogoodrdquo and others
as ldquoimmoralrdquo or ldquobadrdquo4
When teaching ethics to undergraduates at a secular school I
often hand out this Bundy quotation but without identifying the
speaker I then ask them to write a paragraph on whether they
agree with its basic idea Most students approve of the unknown
authorrsquos sentiments I then reveal that this statement was the
philosophy of one of the most infamous serial killers in American
historymdashthe philosophy that allowed and even impelled hisegregious crimes Next I ask them to reconsider their judg-
ments Te results are usually mixed but the majority of stu-
dents show dismay and surprise that they were in agreement
with a view that justified serial rape and murder
Yet today a television seriesmdasha comedy nonethelessmdashis about
a serial killer named Dexter o top that off there is even a book
called Dexter and Philosophy Mind over Spatter Can such atroc-
ities be lifted so easily from bloody reality and into a neutral
realm of entertainment For many it can and so they seem to
agree with Protagoras at least implicitly there is no objective

us and nothing beneath us It is all merely neutral and we make
the callmdashon everything ldquoMan is the measure of all thingsrdquoSo then what does this sentence tell us about philosophy and

on this basis But a statement cannot be true unless it accords
with the way the world in fact is and the way we in fact are Pro-
tagoras does capture some truths about perspective For ex-
ample my tastes in food determine how I measure the goodness
of the food I am the measure of that at least It matters nothing
whether a connoisseur thinks me an ignoramus I can only
measure it by what I experience at the moment In that way I am
the measure but am I the expert Am I the knowerTere is a strange implication for Protagorasrsquos view In the
Teaetetus Protagoras even states that error is impossible5 Al-
though he was a teacher he cannot by his own lights teach
anyone o this Socrates inquires
If whatever the individual judges by means of perception is
true for him if no man can assess anotherrsquos experiencebetter than he or can claim authority to examine another
manrsquos judgment and see if it be right or wrong if as we
have repeatedly said only the individual himself can judge
of his own world and what he judges is always true and
correct how could it ever be my friend that Protagoras
was a wise man so wise as to think himself fit to be the
teacher of other men and worth large fees while we in
comparison with him the ignorant ones needed to go and
sit at his feetmdashwe who are ourselves each the measure of
his own wisdom6

human languages For example the general concept of cat may
be written in Chinese or in English Since each language uses
different symbols for writing its graphic inscription for cat will
differ Tis is true for voicing the word cat as well Trough a
long messy process not instigated by any central planning each
culture selects its own conventions of communication Are not
these two systems of writing measuring reality in very different
ways In point of fact they are not
Both kinds of writing systems (as well as other means ofcommunication) make claims about a reality that are outside
of the systems themselves and outside of the individuals who
use the pictographic or ideographic methods We tacitly saw
this earlier But in both cases a cat is invoked there is a single
referent Te differences in linguistic custom are not differ-
ences in content A cat is a cat in whatever language and it will
not bark however it may be measured Moreover while it may
be vexing in places one can translate a book from English to
Chinese Not everything is lost in translation in fact more is
found than is lost ranslators need have no fear of losing their
livelihood
Staying on matters of taste for a moment (and not morality
for now) are all people equally skilled in measurement Tepoet and literary critic S Eliot advocated the cultivation of

reading when you were quite young Tey are likely not the
same as when you became an adult You may still enjoy and
laugh at nursery rhymes but your tastes have expanded Yes
you still love Winnie the Pooh (and I mean the original Pooh
not the Walt Disney version) but you understand and appre-
ciate it more deeply now If so (and substitute your own ex-
amples here if needed) your tastes have at least changed and

likely age appropriate but they were limited and (not unex-
pectedly) childish Te apostle Paul notes this in a well-known
turn of phrase ldquoWhen I was a child I talked like a child I
thought like a child I reasoned like a child When I became a
man I put the ways of childhood behind merdquo ( Corinthians
see also Hebrews -)
Furthermore the very notion of improvement or progress
(not merely some change in quality) requires and assumes an
objective standard by which to measure improvement (or de-cline) If a baseball batter hits in and in he
has improved based on the best possible average of Tere
is a measurement and it is not the perception of the batter that
determines this measurement Tis is the case in the arts as well
Few knowledgeable about jazz would dispute that John Col-
tranersquos saxophone work improved during his tenure with pianist
Telonious Monkrsquos quartet or that it developed further in Col-
trane own ldquoclassic quartetrdquo (ndash)7 Here the assessment is
not quantitative or statistical but qualitative One might object
that this is a purely subjective judgment (such as whether one
feels hot or not) which is relative to the person hearing Who is
to judge Te answer is straightforward the one whose expe-
rience knowledge and wisdom merit approval Although manydrink wine there are few expert wine tasters A student of mine
is so adept at this art that he can tell what part of the country a
wine came from Not having developed this advanced degree of
skill this is foreign to me However I had no inclination to say
that my judgment on wine is as accurate as Markrsquos Along these
lines I was once embarrassed when one of my students told me
that the wine I was enjoying was ldquothe Kenny G of winesrdquo Tis as
jazz aficionados know was not a compliment about the wine or
about my taste for wine

I have not even given clear aesthetic criteria8 My point is that
beauty is not only in the eye of the beholder If not we are haunted

But Herodotus may yet rescue Protagoras In his History the
ancient historian notes that Darius a king of ancient Persia (who
was a kind of premodern anthropologist because of his study of
cultural differences) called together some Greeks and askedthem what it would take to cannibalize their dead fathers Te
Greeks needed no time to ponder the proposition since nothing
would move them to such odious paternal desecration Teir
practice was cremation this alone would honor their dead Ten
Darius summoned several Callatians (from India) to join the
Greeks and asked them what would make them cremate their
deceased fathers Te Callatians were as horrified as the Greeks
had been and told Darius to not discuss such atrocities
Had Protagoras heard this he would likely applaud having
found more evidence for his outlook But not all applause is
earned While the Greeks and Callatians observed fundamen-
tally different funeral rites both cultures honored the dead Tat
is only particular practicesmdashnot just any old or new thingmdashwere esteemed right and good in the treatment of corpses and
these practices were not norms for the treatment of the living
In other words death was set apart as uniquely meaningful and
thus required that the living treat the dead with ritual respect
Tus Greeks and Callatians agreed on a deep principle of hon-
oring the dead Tey disagreed on the rule that stems from that
principle In no sense then does the example of cultural rela-
tivity disprove moral agreement across cultures since there was
deep agreement between the cultures C S Lewis makes just
this point in Mere Christianity

Protagoras
I know that some people say the idea of a Law of Nature or
decent behaviour known to all men is unsound because
different civilisations and different ages have had quite dif-
ferent moralities
But this is not true Tere have been differences between
their moralities but these have never amounted to any-
thing like a total difference If anyone will take the trouble
to compare the moral teaching of say the ancient Egyp-
tians Babylonians Hindus Chinese Greeks and Romanswhat will really strike him will be how very like they are to
each other and to our own9
Te case against Protagoras comes down to this If we want to
learn anything if we want to improve as human beings if we
want to condemn the ed Bundys of the world if we want any
kind of educated taste if we desire to understand and honorhumanity then we must reject the ldquoman is the measurerdquo theory
Each person is indeed the measurer of some things Some of
them the individual gets right some of them the individual gets
wrong And in this difference lies all the difference in the world
and even outside of it

PREFACE
Inspiration is an odd beast enlightening here and deceiving
there Inspiration sometimes comes through epiphany seem-
ingly out of nowhere and resplendent with originality and beauty
Some works of great music appear in this way Friedrich
Nietzsche wrote his anti-Gospel Tus Spoke Zarathustra in a
fit of literary effusion lasting only two weeks Te result hasbaffled millions for a century
Philosophy in Seven Sentences came into being rather quickly
after a lifetime of engaging philosophy after many discussions
and arguments about philosophy after three academic degrees
in philosophy after attending (too) many conferences about phi-
losophy after grading many papers about philosophy (both
good and evil) after publishing much about philosophy after
changing some of my views on philosophy and after sometimes
questioning my own ability to do philosophy well
I was inspired by recent popular books featuring numbers
and objects in the titles such as A History of the World in
Objects by Neil MacGregor A History of the World in Six Glasses
by om Standage and Te Smithsonianrsquos History of America in Objects by Richard Kurin My object for organizing and in-
troducing philosophy was not a physical object but an object of
thought a sentence Te number seven seemed right given the

alliteration and because I was drawn to just these philosophi-
cally pregnant sentences My hope is that the book will introduce
the beginner to the craft of philosophy A seasoned reader might
find ideas worth consulting afresh or even for the first time
Philosophy is a many-splendored discipline Miniature books
such as this must fail to lasso everything and will leave many
critters hurdling about in the pasture unnamed and unattended
o talk shop Philosophy in Seven Sentences is most concerned
with epistemology (how and what we can know) and metaphysics (the study of being) ravelers through the book will also read a
bit about moral philosophy and aesthetics
Philosophers have biographies although their philosophies
are not limited to their biographies So each chapter includes a
bit of their stories (A few of my stories appear as well) Since
philosophers argue and agree with other philosophers I con-
sider their intellectual relationship with others in the guild par-
ticularly those philosophers whose sentences we engage Dia-
logue and debate down through the ages is the conversation of
philosophy Overhearing it may spark truth in our souls or at
least clear away some errors of thought
I do not take up theology directly but each of the seven sen-
tences bears on questions concerning God the universe andhumanity I am not sure why anyone would be interested in phi-
losophy otherwise
I have many to thank but room for only a few Jason Crowder
found references for Augustine and Pascal that eluded me (to my
shame) My colleague Sarah Geis gave excellent commentary on
Descartes Elizabeth Johnson contributed some dandy editing
Rebecca Merrill Groothuis prayed for this book project as she
has for all my other ones Tanks also to the administration of
Denver Seminary for granting me a sabbatical during which

Introduction
PHILOSOPHY IN ONLY
SEVEN SENTENCES
Can we tackle some of the key questions and answers in
philosophy through just seven sentences by seven famous
philosophers I wager we can so we will Many other sentencesmdash
or paragraphs or booksmdashcould have made the cut Because of
this some will argue that my selection was biased ignorant or
slanted If so let them philosophize over it After all that is the
purpose of this book to think and act philosophically
I make no claim that Philosophy in Seven Sentences is repre-
sentative of philosophy as a whole I chose these authors and
their sentences for several reasons First I was familiar with
them As I point out several times many of these ideas havedeep autobiographical significance to me Second they raise
issues pertinent to our day Tird each sentence is fairly well
known none is esoteric1 I also chose these authors because
their arguments were clear enough to be well suited to philo-
sophical analysis even on a popular level2
Some may think that popular philosophy is an oxymoron a
silly contradiction not worthy of a momentrsquos thought Phi-losophy is of course for expertsmdashthose who have accumulated
vast student-loan debts after which they have logged long and
lonely years in the classroom studying at their desks and ar-

guing with other philosophers about philosophy Tese strange
souls are abstruse esoteric recondite and many other long
pompous words not meant for the masses Philosophers write
for each other argue with each other and often flummox or bore
the hapless college students whose academic requirements put
them in their presence
And so it is for many philosophers but not for all of them At
its most ancient root philosophy was meant to initiate us into
ldquothe good liferdquo to tutor us for the ongoing experience ofknowledge and virtue Since everyone lives some kind of life
philosophy explored the mindrsquos abilities to live life in accord
with reality At best it helps scratch the itch of human exis-
tencemdashor at its worst it rubs the wound raw Even though ety-
mology (the study of word origins) may deceive it does its work
well in understanding the origin of philosophy telling us that
its two Greek parts are love ( philos) and wisdom ( sophos) Phi-
losophers may not always love wisdom but that is their disci-
plinersquos pedigree Te Hebrew Bible warns in the book of
Proverbs that both wisdom and folly call out for reflection and
allegiance Te wise are diligent in learning facing the facts in
earnest while the fool sacrifices character for ignorance and
untutored pleasure But knowledge beckons nevertheless atleast in our better moments As Aristotle wrote ldquoAll men by
nature desire to knowrdquo (We will examine this sentence shortly)
Any thinking person may join philosophyrsquos discussion which
rings down through the ages Tat is the aim of this small book
which I hope can be read profitably by both philosophical neo-
phytes and seasoned philosophers whatever their worldview
may be My aims are catholic (universal) however parochial my
selections may seem to some
Philosophy is not a closed club or a secret society Since we
all can think about ultimate questions letrsquos do it For the record

Philosophy in Only Seven Sentences
I propose that the requirements for being a philosopher (whether
good or bad major or minor professional or layperson) are a
strong and lived-out inclination to pursue truth through the rig-
orous use of human reasoning and to do so with some intel-
lectual facility But sadly even some philosophers disavow the
search for truth In Whatrsquos the Use of ruth French philosopher
Pascal Engel writes ldquoTere is no obligation to say or to be-
lieve that which is truerdquo3 If so why should we read his writings
or those of any other philosopherIs then everyone a philosopher Everyone muses a bit on
where we came from who we are and where we are going But
not all do this very well So while Johnny Rotten (b ) of the
Sex Pistols addressed some philosophical themes in his punk
rock compositions and performances one is reluctant to give
him the title of philosopher Tis is because it is a kind of merit
badge reserved for the few I was recently asked by a precocious
ten-year-old named Liam if I was a philosopher I said I was
Ten he asked ldquoWhat do you dordquo My reply was ldquoI think a lot
about argumentsrdquo We then discussed the nature of an argument
With a little coaxing he told me what an argument was giving
reasons for what you believe often in conversations with those
who believe otherwise I have recruited him for graduate studyin my program
o enjoin the discussion of philosophy I will appeal to seven
sentences all of which are short but none of which are trivial
Some are more renowned than others A few of them are famous
Tese statements are not impenetrable deceiving the unwary
inquirer with obscurity masquerading as profundity Sadly not
a few philosophers cloak their ideas with idiosyncrasies and un-
necessary jargon Not so for a Socrates or Jesus who went about
speaking the common tongue in uncommon ways to both
common and uncommon people Te public square was their

classroom and all comers were their students Neither wrote a
word but their words are unforgettable as we will see Teir
ideas are affirmed and denied by the simplest and most sophis-
ticated thinkers
While we cannot directly encounter the likes of Socrates or
Jesusmdashor the more bookish philosophers such as Plato Aris-
totle Augustine Descartes and kindredmdashwe can interrogate
them and investigate the perennial questions they address the
nature of truth how we gain knowledge the meaning of humanexistence death the source of morality and more In my many
years as a teacher and learner of this antique art I find to my
dismay that too many students too often give up too soon Tey
face an intellectual difficulty some demanding reading or differ-
ences of opinion and they cash in their chips despite my provo-
cations cajoling and (on occasion) anger It need not be and
should not be so S Eliot should kindle a flame in us ldquoBut our
lot crawls between dry ribs to keep our metaphysics warmrdquo4
I first read Eliotrsquos line in and never forgot it Who could
unless he or she were skimming Martin Heidegger despite his
murky prose was right in calling our lives a ldquobeing unto deathrdquo
because our eventual demisemdashgradual or instantmdashbrackets
everything we think or do or hope ldquoNo one gets out of here aliverdquois no tired clicheacute unhappily Samuel Johnson put it well ldquoDepend
upon it Sir when a man knows he is to be hanged in a fortnight
it concentrates his mind wonderfullyrdquo5 Our mortality sets limits
on all our endeavors including philosophizing Tere is like it
or not a flashing stop sign ahead on the road So why not think
well now Or at least try to We can take or steal some calmly
measured time to muse on what matters most and we have

crowd by some wags and is even a byword ldquoYou sophistrdquo Te
charge is that Sophists cared nothing for truth but cared every-
thing about being paid to philosophize for a vested interest
More on these philosophers-for-hire later Even so this oldGreek crystallizes the thought of not a few philosophers and
nonphilosophers Our chosen sentence sums it up
Man is the measure of all things of the things which are
that they are and of things which are not that they are not6
Protagoras gives wings to an idea that many ponder try our
hardest (or not try at all) we cannot break free of ourselvesmdashour
senses our viewpoints our values even our ldquostuffrdquo Te world is
our judgment and nothing more It does not await our judgment
it is our judgment Tere is no objective truth but only various
views from various places at various times by various people
Tings are not our measure but we are the measure of them
Hence Protagoras is the spokesman for relativism sometimescalled nonrealism or perspectivism It is not just that we have no
(or limited) access to objective reality Tat is skepticism Reality
is pretty much exhausted by our perceptions and thoughts Te
real world is our world Myriads have measured Protagoras

wisdom can ignore him His ghost haunts us still Is there a phil-

students to live this waymdashfor their sakes and mine (It makes for
better papers too) Tus said Socrates the gadfly (or pain-in-
the-neck) of ancient Athens Like Protagoras we know of
Socrates through those who knew his work but unlike Pro-
tagoras we have more substantial sources particularly Plato
And Socrates is a household name Not incidentally the man
who was not an author ended up being the inspiration for the
prolific Plato who was the worldrsquos first systematic philosopher
As philosopher Alfred North Whitehead discerned ldquoTe safestgeneral characterization of the European philosophical tradition
is that it consists of a series of footnotes to Platordquo7 Te footnotes
may praise (Augustine) or blame (Aristotle) but footnotes are
everywhere as well as entire volumes
aking up Socratesrsquos philosophical challenge means exam-
ining just what his famous sentence means in itself and what it
means for us What might an examined life be given the distrac-
tions and overstimulation of postmodern times For Socrates
there is a way to calm the mind and search things out But is
there a place for Socratic dialogue today outside the Socratic
method of many law schools Further old Plato Socratesrsquos
chronicler and student may offer us wisdom pertaining to the
nagging questions of philosophy as he spurns the work of the philodoxers (lovers of opinion) and promotes the call of the phi-
losophers (lovers of wisdom) Worse yet were the misologists (one
of the Platonic corpusrsquos most winning words) those who took an
active role in hating the use of reason itself We may find some
today even in educated enclaves or even on the bestsellers lists
But one can also find Aristotle in popular bookstores always
in the philosophy section (along with less prestigious volumes
such as Led Zeppelin and Philosophy which we must pass over
without further comment) When Aristotle wrote ldquoAll men by
nature desire to knowrdquo he did not mean just the scholars or

teachers but ldquomanrdquomdashthe human race in all its circumstances and
variations Tat means every person whatever social standing
vocation or intelligence Although Aristotle was no egalitarian
(he thought that women were inferior to men and that some were
born to be slaves) he nevertheless appeals to a universal human
condition the desire to get reality right in the time that we have
Augustine the first great Christian philosopher like Socrates
before him strikes a personal note concerning getting reality
right Having examined himself and the leading philosophies ofhis day (including Plato and his footnotes) he confesses with a
cry of the heart addressed to God ldquoYou have made us for
yourself and restless is our heart until it comes to rest in yourdquo
Tis cry is not commonplace as in ldquoMy spirituality gives me
meaningrdquo It is instead the beginning of an argument told in his
autobiography In fact it may be the first autobiography on
record It is no doubt the first philosophical autobiography (if
we exclude the book of Ecclesiastes) Te irascible Jean-Jacques
Rousseau is well known for his autobiography as well but a short
book can only do so much8
Skipping madly over much philosophical history (without any
irreverence or glibness) we arrive at Reneacute Descartes the much
maligned but seldom understood ldquofather of modern philosophyrdquoDescartes was troubled by opinions without backingmdashthose
ideas about ultimate matters untethered from certainty Skep-
ticism was his foe as it is in one way or another for any philos-
opher Tis is because the question arises How do you know
what you claim to know Mere social position or historical tra-
dition will not cinch the deal for this philosopher and scientist
In our language (which itself needs interrogation) the man
ldquowanted proofrdquo While ldquoI donrsquot knowrdquo is often the most knowl-
edgeable answer it should not be the default response according
to Descartes Tis apprehension led him on a quest that began

with himself Like Augustine but in briefer scope he put this in
autobiographical form in Discourse on Method and to some
extent in Meditations on First Philosophy But Descartesrsquos quest
did not end with himself unlike so much contemporary self-
help literature He is famous for the sentence ldquoI think therefore
I amrdquo But God himself has something to do with that sentence
For Descartes there was no leap of faith in it either Reason was
the guide But how far can reason take us
A contemporary of Descartes had an idea ldquoTe heart has itsreasons that reason knows nothing ofrdquo wrote Blaise Pascal who
was the best phrasemaker of the lot of our philosophers Tis
statement is a window into a worldview Humans have the ca-
pacity to calculate and reason methodically but they may also
know some things by tracing out the contours and resources of
ldquothe heartrdquomdashanother organ of knowledge Philosophers study
many thinkers but few come to love few of them (My graduate
seminar on Kantrsquos Critique of Pure Reason was well worth it but
was no love affair) Pascal on the contrary is much loved by many
He is so loved that people even love things he never actually said
such as ldquoTere is a God-shaped vacuum that only God can fillrdquo
But this paraphrase is not far off the mark though it should be
placed within a larger perspective of Pascalrsquos philosophyTe French polymathrsquos philosophy is far more fascinating than
the CliffsNotes version allows Pascal did not put faith in place
of reason and he was not a one-trick philosopher (Pascalrsquos
wager) Slander and libel have fouled the air about him ob-
scuring his sophisticated treatment of the cost-benefit sense of
believing in religion or not Yet he was neither knave nor poser
Te founder of probability theory and the inventor of the first
working calculating machine had reasons for faith Like Des-
cartes he was bugged by skepticism and like Descartes he ap-
pealed to human nature as a place to start the discussion

Philosophy in Only Seven Sentences
Our last sentence is not as well known as the previous ones
but it opens a door of inquiry for us
Te greatest hazard of all losing onersquos self can occur very
quietly in the world as if it were nothing at all
It was penned by an idiosyncratic and famously melancholy
Dane named Soslashren Kierkegaard a philosopher intensely inter-
ested in the self in relation to ultimate reality Tis should sound
familiar since all philosophers have expressed this interest inone way or another But Kierkegaardrsquos way was in a sense as
much psychological as philosophical He intrepidly limned the
inner workings of the self of consciousness in philosophical
categories Like Pascal Kierkegaard wanted to strip away
through existential analysis the layers and dynamics of the self
that keep reality at bay Unlike Pascal and the other philosophers
he was more interested in the analysis of the self than presentingit with arguments for an abstract objective reality Tis may
sound a bit unphilosophical but it is not But that takes time to
tease out properly as I hope you will see
Our seven sentences may be viewed as several doors into
worlds previously unknown Or they may be our irritants to
prod us to move away from facile factoidsmdashldquoDo your own thingrdquoldquoFollow your blissrdquo ldquoKeep Calm and Carry Onrdquomdashto more so-
bering reflections9 Perhaps the sentences are bridges to other
lands of thought Tese philosophical sentences do not sum the
thought of any of the philosophers for these thinkers are far too
deep for that Nor do the seven sentences aim to summarize the
history of philosophy Tat would be a pompous and laughable
claim Some things cannot be put into a nutshell including thenutshell itself But I claim that philosophical activity can be
sparked by just seven sterling sentencesmdashand who knows where
it might lead

PROTAGORAS
Man is the measure of all things
P
Greeks could do philosophy Te basic questions of exis-
tence have never been far from the human mind but the
ancient Greeks excelled at this and their musingsmdashsome frag-
mentary or secondhandmdashhave been preserved in written texts
However much philosophy occurred in exclusively oral cultures
the Greeks valued writing in addition to oral memory and tra-
dition Socrates you remember wrote nothing but generated a vast literature though his dialogues A lesser-known figure who
came after him did write a few things and his famous adage is
worth considering
Protagoras (fifth century BC) is not to be confused with
like-sounding ancient Greek thinkers named Pythagoras or
Parmenides who along with others were pre-Socratic thinkers
(Tis shows the significance of Socrates since philosophy isdated with respect to his life) Tese thinkers are worth inter-
rogating as well and I studied them with profit in a year-long
course in ancient philosophy forty years ago Protagoras

stands out to us though because of his adage about absolute
assessment
Man is the measure of all things of the things which are
that they are and of things which are not that they are not1
His claim is not simply that people measure thingsmdashsuch as
character chariots boats and fishmdashbut that each human is the
measure Each person is the assessment or judgment What
could this mean No person is a slide ruler or scale or Geigercounter although we avail ourselves of such things
W I M
We tend to think that people use a standard of measurement
outside of themselves Even inadequate and one-dimensional
measures such as onersquos IQ score are not determined by how we
feel about themmdashand Mensa is very picky about thisOn the other hand Protagoras has Shakespearersquos Hamlet on
his side at least concerning morality ldquoFor there is nothing either
good or bad but thinking makes it sordquo2 Tat is morals do not
have objective standing rather they are judged differently by
different people Tis quote is from a discussion about Denmark
which Hamlet unlike his interlocutor Rosencrantz said was ldquoaprisonrdquo If Hamlet is right then both Hamlet and Rosencrantz
are right about Denmark
What then was Protagorasrsquos point (Wersquoll put serious Shake-
spearian interpretation aside) o find out we need to take a step
back into the Greek philosophical scene and not rush to
judgmentmdashor rush to endorsement either Protagoras would ap-
prove of this deliberationProtagoras was considered the chief of the Sophists intellec-
tuals who were paid to defend the views of their sponsors Tey
were accomplished orators as well as thinkers Originally the

term sophist meant something like our ldquoprofessorrdquo but later a
Sophist was deemed a hired gun a philosopher for hire and one
having no principles of his own Teir arguments supposedly
were merely the instruments of the will of their bosses One may
argue over the virtues of the Sophists but it is certainly not true
that being paid for philosophizing necessarily disqualifies the
employeersquos arguments On the other hand if we think of a
Sophist as something like a political speech writer or the like
our judgment will change Whatever the intellectual rectitudeof Protagoras he was a perpetual lecturer who articulated and
debated ideas in the marketplace a marketplace of ideas that yet

Protagoras was one of a spirited group of fastidious thinkers
who tired or at least grew skeptical of Greek mythology with
its pantheon of gods Yes the stories of the gods were often riv-
eting and worth repeating A recent volume by Luc Ferry is
called Te Wisdom of the Myths How Greek Mythology Can
Change Your Life3 Tere was always a moral to the story Her-
cules the last son of Zeus was a dashing and dramatic character
who started as a mighty mortal and became a god upon deathAlthough a bit impetuous and lacking in sobriety he plays well
as a hero Zeus himself is the apotheosis of power but acts
largely without moral authority Even the might of Zeus does not
support the idea that ldquomight makes rightrdquo since might may make
for divine mischief My point is not to survey or psychoanalyze
the denizens of Greek mythology but to make a general point
Mythologies may inspire and guide to some extent our relation
to the hard facts of family life death and sexuality (and some of
the gods tended to be naughty in this way)
Nevertheless the problem with Greek mythology (or any

mythology Eastern or Western) is simply that it is mythology it
is neither history nor clearly articulated philosophy In too many
ways the gods despite their thespian reacutesumeacutes and magical
powers were not much more than semi- glorified mortals Tis
was the objection of a growing group of Greeks who were mere
mortalsmdashmortals with meaning metaphysics and morality on
their minds And what might the mind do when free to explore
life and its questions apart from the venerable stories of Greek
fascination It might philosophize and so it didProtagoras and his cohorts quested for explanations of a more
abstract but also compelling sort than the old tales could afford
Tey sought principles to explain facts in a universal and logi-
cally coherent manner o be a little unfair to the mythologies
consider the tooth fairy She adds some magical benevolence to
the loss and placement of a baby tooth for children but the fairy
story adds nothing about the nature of benevolence the signifi-
cance of teeth or the significance of the humans who grow and
lose these teeth whether through development (teething) or
decay (the toothless)
Tus to give one example Tales of Miletus tried to find a
cosmic commonality to all things He divined it as water Yes
water which was more than rain oceans lakes and puddles Itwas everywhere so perhaps it was the root and branch of every-
thing Water or moisture in general lives in the clouds in plants
in animals (aquatic land or amphibious) and in thirsty mortals
It condenses and evaporates but never leaves the planet Con-
sidering the presence and power of water Tales extrapolated
that water was more than one more thing on earth however
necessary for life It was rather the unifying principle for exis-
tence Whatever we think of Tales his thinking is not absurd
and it indicates a thirst for philosophical explanation as opposed
to mythological meanderings At least he was trying

But it is Protagoras who calls for our attention Instead of ar-guing for something at the heart of everything (water for Tales)
a principle found in nature Protagoras moved back from nature
to the self After all skeptics had questioned mere mortalsrsquo
ability to know with any confidence what is out there inde-
pendent of themselves Te jaundiced eye sees things differently
from the nonjaundiced eye Children perceive entities invisible
to adults Adults sometimes hallucinatemdashbut perhaps they areseeing what most miss One woman feels cold in a room of degF
and another feels hot Age alters hearing seeing memory and
may jangle judgments Te upshot is that we cannot find a place
to stand to see the world as it is We are simply ill-equipped to
do so Objective truth what is independent of our perceptions
endlessly and mercilessly eludes us
We will return to skepticism when discussing Descartes and
Pascal but Protagoras was not a skeptic He did not withhold
judgments about facts in themselves because we do not have the
ability to know them While recognizing that the skeptics had
dethroned our intellectual confidence in capturing objective re-
ality his point of departure was this we do know our own view-
points judgments and beliefs Tat is we measure things theydo not measure themselves So I take most of Francis Baconrsquos
paintings to be ugly and thus unattractive I am repulsed Tis is
the end of the story or my story Tis is my measurement You
on the contrary may find delight in Baconrsquos tortured figures and
color schemes Tat is your measurement and the end of your
story
Now reconsider the skeptical point made earlier One person
can deem the room cold and another hot Te skeptic might say
we cannot know then what the room is given the variability in
perception But Protagoras claims that the room is hot for person

A and not hot for person B Tere is no contradiction since we
are considering individual perceptions Tere are two measure-
ments each of which is valid Tus Bacon is barbaric to me and
beautiful to youmdashand that is the level best we can do Or perhaps
I will come to adore Baconrsquos paintings and heap scorn on my
former judgment If so then that is my measurement
Tis is rather attractive at first blush After all there is no
dispute in matters of taste or to be more snobby De gustibus
non est disputandum Te avant-garde saxophone playing ofPeter Broumltzmann can send me into the upper reaches of aes-
thetic delight while sending others scurrying from the room
while covering their ears But Protagoras took this insight far
beyond artistic judgments Notice the reference range (or extent)
of Protagorasrsquos statement ldquoMan is the measure of all thingsrdquomdash
matters of taste as well as matters of fact matters of principle
and matters of matter Nothing is excluded
Let us follow this out As we think it through the old Greek
will sound much like modern man If Protagoras is right then
there is no disputing matters of morality either Man is the
measure of what is right and what is wrong what is virtuous and
what is vicious what should be loved and what should be hatedmdash
just as Hamlet claimed oday this thinking is usually put in thelanguage of choice instead of measurement but the idea is the
same If you chose to do X that choice is the end of the matter
Or to suit Protagoras if you measure X as worth doing then it
is worth doing Tis is true whether X refers to sailing stealing
or stampeding cattle in the direction of a Cub Scout outing
But we might say ldquoWho is to judgerdquo Who of us can stand
above him- or herself and others and become objective Yes we
recoil from some ideasmdashsuch as torturing the innocent merely
for pleasure or female genital mutilation But what does that tell
us about reality if there really is such a thing as reality Te claim

that ldquoman is the measure of all thingsrdquo is an all-encompassing
judgment itself Te answer to ldquoWho is to judgerdquo is that we are

human judgment by which it might be judged But why would

I learned that all moral judgments are ldquovalue judgmentsrdquo
that all value judgments are subjective and that none can
be proved to be either ldquorightrdquo or ldquowrongrdquo I even read some-where that the Chief Justice of the United States had written
that the American Constitution expressed nothing more
than collective value judgments Believe it or not I figured
out for myselfmdashwhat apparently the Chief Justice couldnrsquot
figure out for himselfmdashthat if the rationality of one value
judgment was zero multiplying it by millions would not
make it one whit more rational Nor is there any ldquoreasonrdquo
to obey the law for anyone like myself who has the
boldness and daring ldquothe strength of characterrdquo to throw
off its shackles
I discovered that to become truly free truly unfettered
I had to become truly uninhibited And I quickly discovered
that the greatest obstacle to my freedom the greatest blockand limitation to it consists in the insupportable ldquovalue

historymdashthe philosophy that allowed and even impelled hisegregious crimes Next I ask them to reconsider their judg-

on this basis But a statement cannot be true unless it accords
with the way the world in fact is and the way we in fact are Pro-
tagoras does capture some truths about perspective For ex-

of the food I am the measure of that at least It matters nothing
whether a connoisseur thinks me an ignoramus I can only
measure it by what I experience at the moment In that way I am

though he was a teacher he cannot by his own lights teach
anyone o this Socrates inquires
If whatever the individual judges by means of perception is
true for him if no man can assess anotherrsquos experiencebetter than he or can claim authority to examine another
manrsquos judgment and see if it be right or wrong if as we
have repeatedly said only the individual himself can judge
of his own world and what he judges is always true and
correct how could it ever be my friend that Protagoras
was a wise man so wise as to think himself fit to be the
teacher of other men and worth large fees while we in

sit at his feetmdashwe who are ourselves each the measure of
his own wisdom6

be written in Chinese or in English Since each language uses
different symbols for writing its graphic inscription for cat will
differ Tis is true for voicing the word cat as well Trough a
long messy process not instigated by any central planning each
culture selects its own conventions of communication Are not
these two systems of writing measuring reality in very different
ways In point of fact they are not
Both kinds of writing systems (as well as other means ofcommunication) make claims about a reality that are outside
of the systems themselves and outside of the individuals who
use the pictographic or ideographic methods We tacitly saw
this earlier But in both cases a cat is invoked there is a single
referent Te differences in linguistic custom are not differ-
ences in content A cat is a cat in whatever language and it will
not bark however it may be measured Moreover while it may
be vexing in places one can translate a book from English to

Furthermore the very notion of improvement or progress
(not merely some change in quality) requires and assumes an
objective standard by which to measure improvement (or de-cline) If a baseball batter hits in and in he
has improved based on the best possible average of Tere
is a measurement and it is not the perception of the batter that
determines this measurement Tis is the case in the arts as well
Few knowledgeable about jazz would dispute that John Col-
tranersquos saxophone work improved during his tenure with pianist
Telonious Monkrsquos quartet or that it developed further in Col-
trane own ldquoclassic quartetrdquo (ndash)7 Here the assessment is
not quantitative or statistical but qualitative One might object
that this is a purely subjective judgment (such as whether one
feels hot or not) which is relative to the person hearing Who is
to judge Te answer is straightforward the one whose expe-
rience knowledge and wisdom merit approval Although manydrink wine there are few expert wine tasters A student of mine
is so adept at this art that he can tell what part of the country a
wine came from Not having developed this advanced degree of
skill this is foreign to me However I had no inclination to say
that my judgment on wine is as accurate as Markrsquos Along these
lines I was once embarrassed when one of my students told me

But Herodotus may yet rescue Protagoras In his History the
ancient historian notes that Darius a king of ancient Persia (who
was a kind of premodern anthropologist because of his study of
cultural differences) called together some Greeks and askedthem what it would take to cannibalize their dead fathers Te
Greeks needed no time to ponder the proposition since nothing
would move them to such odious paternal desecration Teir
practice was cremation this alone would honor their dead Ten
Darius summoned several Callatians (from India) to join the
Greeks and asked them what would make them cremate their
deceased fathers Te Callatians were as horrified as the Greeks
had been and told Darius to not discuss such atrocities
Had Protagoras heard this he would likely applaud having
found more evidence for his outlook But not all applause is
earned While the Greeks and Callatians observed fundamen-
tally different funeral rites both cultures honored the dead Tat
is only particular practicesmdashnot just any old or new thingmdashwere esteemed right and good in the treatment of corpses and
these practices were not norms for the treatment of the living
In other words death was set apart as uniquely meaningful and
thus required that the living treat the dead with ritual respect
Tus Greeks and Callatians agreed on a deep principle of hon-
oring the dead Tey disagreed on the rule that stems from that
principle In no sense then does the example of cultural rela-
tivity disprove moral agreement across cultures since there was

Protagoras
I know that some people say the idea of a Law of Nature or
decent behaviour known to all men is unsound because
different civilisations and different ages have had quite dif-
ferent moralities
But this is not true Tere have been differences between
their moralities but these have never amounted to any-
thing like a total difference If anyone will take the trouble
to compare the moral teaching of say the ancient Egyp-
tians Babylonians Hindus Chinese Greeks and Romanswhat will really strike him will be how very like they are to
each other and to our own9
Te case against Protagoras comes down to this If we want to
learn anything if we want to improve as human beings if we
want to condemn the ed Bundys of the world if we want any
kind of educated taste if we desire to understand and honorhumanity then we must reject the ldquoman is the measurerdquo theory
Each person is indeed the measurer of some things Some of
them the individual gets right some of them the individual gets
wrong And in this difference lies all the difference in the world
and even outside of it

Inspiration is an odd beast enlightening here and deceiving
there Inspiration sometimes comes through epiphany seem-
ingly out of nowhere and resplendent with originality and beauty
Some works of great music appear in this way Friedrich
Nietzsche wrote his anti-Gospel Tus Spoke Zarathustra in a
fit of literary effusion lasting only two weeks Te result hasbaffled millions for a century
Philosophy in Seven Sentences came into being rather quickly
after a lifetime of engaging philosophy after many discussions
and arguments about philosophy after three academic degrees
in philosophy after attending (too) many conferences about phi-
losophy after grading many papers about philosophy (both
good and evil) after publishing much about philosophy after
changing some of my views on philosophy and after sometimes
questioning my own ability to do philosophy well
I was inspired by recent popular books featuring numbers
and objects in the titles such as A History of the World in
Objects by Neil MacGregor A History of the World in Six Glasses
by om Standage and Te Smithsonianrsquos History of America in Objects by Richard Kurin My object for organizing and in-
troducing philosophy was not a physical object but an object of

alliteration and because I was drawn to just these philosophi-
cally pregnant sentences My hope is that the book will introduce
the beginner to the craft of philosophy A seasoned reader might
find ideas worth consulting afresh or even for the first time
Philosophy is a many-splendored discipline Miniature books
such as this must fail to lasso everything and will leave many
critters hurdling about in the pasture unnamed and unattended
o talk shop Philosophy in Seven Sentences is most concerned
with epistemology (how and what we can know) and metaphysics (the study of being) ravelers through the book will also read a
bit about moral philosophy and aesthetics
Philosophers have biographies although their philosophies
are not limited to their biographies So each chapter includes a
bit of their stories (A few of my stories appear as well) Since
philosophers argue and agree with other philosophers I con-
sider their intellectual relationship with others in the guild par-
ticularly those philosophers whose sentences we engage Dia-
logue and debate down through the ages is the conversation of
philosophy Overhearing it may spark truth in our souls or at
least clear away some errors of thought
I do not take up theology directly but each of the seven sen-
tences bears on questions concerning God the universe andhumanity I am not sure why anyone would be interested in phi-
losophy otherwise
I have many to thank but room for only a few Jason Crowder
found references for Augustine and Pascal that eluded me (to my
shame) My colleague Sarah Geis gave excellent commentary on
Descartes Elizabeth Johnson contributed some dandy editing

has for all my other ones Tanks also to the administration of

Introduction
PHILOSOPHY IN ONLY
SEVEN SENTENCES
Can we tackle some of the key questions and answers in
philosophy through just seven sentences by seven famous
philosophers I wager we can so we will Many other sentencesmdash
or paragraphs or booksmdashcould have made the cut Because of
this some will argue that my selection was biased ignorant or
slanted If so let them philosophize over it After all that is the
purpose of this book to think and act philosophically
I make no claim that Philosophy in Seven Sentences is repre-
sentative of philosophy as a whole I chose these authors and
their sentences for several reasons First I was familiar with
them As I point out several times many of these ideas havedeep autobiographical significance to me Second they raise
issues pertinent to our day Tird each sentence is fairly well
known none is esoteric1 I also chose these authors because
their arguments were clear enough to be well suited to philo-
sophical analysis even on a popular level2
Some may think that popular philosophy is an oxymoron a
silly contradiction not worthy of a momentrsquos thought Phi-losophy is of course for expertsmdashthose who have accumulated
vast student-loan debts after which they have logged long and
lonely years in the classroom studying at their desks and ar-

guing with other philosophers about philosophy Tese strange
souls are abstruse esoteric recondite and many other long
pompous words not meant for the masses Philosophers write
for each other argue with each other and often flummox or bore
the hapless college students whose academic requirements put
them in their presence
And so it is for many philosophers but not for all of them At
its most ancient root philosophy was meant to initiate us into
ldquothe good liferdquo to tutor us for the ongoing experience ofknowledge and virtue Since everyone lives some kind of life
philosophy explored the mindrsquos abilities to live life in accord
with reality At best it helps scratch the itch of human exis-
tencemdashor at its worst it rubs the wound raw Even though ety-
mology (the study of word origins) may deceive it does its work
well in understanding the origin of philosophy telling us that
its two Greek parts are love ( philos) and wisdom ( sophos) Phi-
losophers may not always love wisdom but that is their disci-
plinersquos pedigree Te Hebrew Bible warns in the book of
Proverbs that both wisdom and folly call out for reflection and
allegiance Te wise are diligent in learning facing the facts in
earnest while the fool sacrifices character for ignorance and
untutored pleasure But knowledge beckons nevertheless atleast in our better moments As Aristotle wrote ldquoAll men by
nature desire to knowrdquo (We will examine this sentence shortly)
Any thinking person may join philosophyrsquos discussion which
rings down through the ages Tat is the aim of this small book
which I hope can be read profitably by both philosophical neo-
phytes and seasoned philosophers whatever their worldview
may be My aims are catholic (universal) however parochial my
selections may seem to some
Philosophy is not a closed club or a secret society Since we
all can think about ultimate questions letrsquos do it For the record

Philosophy in Only Seven Sentences
I propose that the requirements for being a philosopher (whether
good or bad major or minor professional or layperson) are a
strong and lived-out inclination to pursue truth through the rig-
orous use of human reasoning and to do so with some intel-
lectual facility But sadly even some philosophers disavow the
search for truth In Whatrsquos the Use of ruth French philosopher
Pascal Engel writes ldquoTere is no obligation to say or to be-
lieve that which is truerdquo3 If so why should we read his writings
or those of any other philosopherIs then everyone a philosopher Everyone muses a bit on
where we came from who we are and where we are going But
not all do this very well So while Johnny Rotten (b ) of the
Sex Pistols addressed some philosophical themes in his punk
rock compositions and performances one is reluctant to give
him the title of philosopher Tis is because it is a kind of merit
badge reserved for the few I was recently asked by a precocious
ten-year-old named Liam if I was a philosopher I said I was
Ten he asked ldquoWhat do you dordquo My reply was ldquoI think a lot
about argumentsrdquo We then discussed the nature of an argument
With a little coaxing he told me what an argument was giving
reasons for what you believe often in conversations with those
who believe otherwise I have recruited him for graduate studyin my program
o enjoin the discussion of philosophy I will appeal to seven
sentences all of which are short but none of which are trivial
Some are more renowned than others A few of them are famous
Tese statements are not impenetrable deceiving the unwary
inquirer with obscurity masquerading as profundity Sadly not
a few philosophers cloak their ideas with idiosyncrasies and un-
necessary jargon Not so for a Socrates or Jesus who went about
speaking the common tongue in uncommon ways to both
common and uncommon people Te public square was their

classroom and all comers were their students Neither wrote a
word but their words are unforgettable as we will see Teir
ideas are affirmed and denied by the simplest and most sophis-
ticated thinkers
While we cannot directly encounter the likes of Socrates or
Jesusmdashor the more bookish philosophers such as Plato Aris-
totle Augustine Descartes and kindredmdashwe can interrogate
them and investigate the perennial questions they address the
nature of truth how we gain knowledge the meaning of humanexistence death the source of morality and more In my many
years as a teacher and learner of this antique art I find to my
dismay that too many students too often give up too soon Tey
face an intellectual difficulty some demanding reading or differ-
ences of opinion and they cash in their chips despite my provo-
cations cajoling and (on occasion) anger It need not be and
should not be so S Eliot should kindle a flame in us ldquoBut our
lot crawls between dry ribs to keep our metaphysics warmrdquo4
I first read Eliotrsquos line in and never forgot it Who could

murky prose was right in calling our lives a ldquobeing unto deathrdquo

upon it Sir when a man knows he is to be hanged in a fortnight

on all our endeavors including philosophizing Tere is like it
or not a flashing stop sign ahead on the road So why not think
well now Or at least try to We can take or steal some calmly
measured time to muse on what matters most and we have

Protagoras is not a household name Google him and find out(Te first entry is not surprisingly Wikipedia) Nor do you find
many academic titles analyzing his ideas although he is often
grouped with the Sophists Tis is considered a disreputable
crowd by some wags and is even a byword ldquoYou sophistrdquo Te
charge is that Sophists cared nothing for truth but cared every-
thing about being paid to philosophize for a vested interest
More on these philosophers-for-hire later Even so this oldGreek crystallizes the thought of not a few philosophers and
nonphilosophers Our chosen sentence sums it up
Man is the measure of all things of the things which are
that they are and of things which are not that they are not6
Protagoras gives wings to an idea that many ponder try our
hardest (or not try at all) we cannot break free of ourselvesmdashour
senses our viewpoints our values even our ldquostuffrdquo Te world is
our judgment and nothing more It does not await our judgment
it is our judgment Tere is no objective truth but only various
views from various places at various times by various people
Tings are not our measure but we are the measure of them
Hence Protagoras is the spokesman for relativism sometimescalled nonrealism or perspectivism It is not just that we have no
(or limited) access to objective reality Tat is skepticism Reality
is pretty much exhausted by our perceptions and thoughts Te
real world is our world Myriads have measured Protagoras
wrong at least on this but no one in pursuit of knowledge and
wisdom can ignore him His ghost haunts us still Is there a phil-
osophical exorcist aboutOur next sentence is often heard but seldom digested I un-
failingly quote it in my first class of introduction to philosophy

students to live this waymdashfor their sakes and mine (It makes for
better papers too) Tus said Socrates the gadfly (or pain-in-
the-neck) of ancient Athens Like Protagoras we know of
Socrates through those who knew his work but unlike Pro-
tagoras we have more substantial sources particularly Plato
And Socrates is a household name Not incidentally the man
who was not an author ended up being the inspiration for the
prolific Plato who was the worldrsquos first systematic philosopher
As philosopher Alfred North Whitehead discerned ldquoTe safestgeneral characterization of the European philosophical tradition
is that it consists of a series of footnotes to Platordquo7 Te footnotes
may praise (Augustine) or blame (Aristotle) but footnotes are
everywhere as well as entire volumes
aking up Socratesrsquos philosophical challenge means exam-
ining just what his famous sentence means in itself and what it
means for us What might an examined life be given the distrac-
tions and overstimulation of postmodern times For Socrates
there is a way to calm the mind and search things out But is
there a place for Socratic dialogue today outside the Socratic
method of many law schools Further old Plato Socratesrsquos
chronicler and student may offer us wisdom pertaining to the
nagging questions of philosophy as he spurns the work of the philodoxers (lovers of opinion) and promotes the call of the phi-
losophers (lovers of wisdom) Worse yet were the misologists (one
of the Platonic corpusrsquos most winning words) those who took an
active role in hating the use of reason itself We may find some
today even in educated enclaves or even on the bestsellers lists
But one can also find Aristotle in popular bookstores always
in the philosophy section (along with less prestigious volumes
such as Led Zeppelin and Philosophy which we must pass over
without further comment) When Aristotle wrote ldquoAll men by
nature desire to knowrdquo he did not mean just the scholars or

teachers but ldquomanrdquomdashthe human race in all its circumstances and
variations Tat means every person whatever social standing
vocation or intelligence Although Aristotle was no egalitarian
(he thought that women were inferior to men and that some were
born to be slaves) he nevertheless appeals to a universal human
condition the desire to get reality right in the time that we have
Augustine the first great Christian philosopher like Socrates
before him strikes a personal note concerning getting reality
right Having examined himself and the leading philosophies ofhis day (including Plato and his footnotes) he confesses with a
cry of the heart addressed to God ldquoYou have made us for
yourself and restless is our heart until it comes to rest in yourdquo
Tis cry is not commonplace as in ldquoMy spirituality gives me
meaningrdquo It is instead the beginning of an argument told in his
autobiography In fact it may be the first autobiography on
record It is no doubt the first philosophical autobiography (if
we exclude the book of Ecclesiastes) Te irascible Jean-Jacques
Rousseau is well known for his autobiography as well but a short
book can only do so much8
Skipping madly over much philosophical history (without any
irreverence or glibness) we arrive at Reneacute Descartes the much
maligned but seldom understood ldquofather of modern philosophyrdquoDescartes was troubled by opinions without backingmdashthose
ideas about ultimate matters untethered from certainty Skep-
ticism was his foe as it is in one way or another for any philos-
opher Tis is because the question arises How do you know
what you claim to know Mere social position or historical tra-
dition will not cinch the deal for this philosopher and scientist
In our language (which itself needs interrogation) the man
ldquowanted proofrdquo While ldquoI donrsquot knowrdquo is often the most knowl-
edgeable answer it should not be the default response according
to Descartes Tis apprehension led him on a quest that began

with himself Like Augustine but in briefer scope he put this in
autobiographical form in Discourse on Method and to some
extent in Meditations on First Philosophy But Descartesrsquos quest
did not end with himself unlike so much contemporary self-
help literature He is famous for the sentence ldquoI think therefore
I amrdquo But God himself has something to do with that sentence
For Descartes there was no leap of faith in it either Reason was
the guide But how far can reason take us
A contemporary of Descartes had an idea ldquoTe heart has itsreasons that reason knows nothing ofrdquo wrote Blaise Pascal who
was the best phrasemaker of the lot of our philosophers Tis
statement is a window into a worldview Humans have the ca-
pacity to calculate and reason methodically but they may also
know some things by tracing out the contours and resources of
ldquothe heartrdquomdashanother organ of knowledge Philosophers study
many thinkers but few come to love few of them (My graduate
seminar on Kantrsquos Critique of Pure Reason was well worth it but
was no love affair) Pascal on the contrary is much loved by many
He is so loved that people even love things he never actually said
such as ldquoTere is a God-shaped vacuum that only God can fillrdquo
But this paraphrase is not far off the mark though it should be
placed within a larger perspective of Pascalrsquos philosophyTe French polymathrsquos philosophy is far more fascinating than
the CliffsNotes version allows Pascal did not put faith in place
of reason and he was not a one-trick philosopher (Pascalrsquos
wager) Slander and libel have fouled the air about him ob-
scuring his sophisticated treatment of the cost-benefit sense of
believing in religion or not Yet he was neither knave nor poser
Te founder of probability theory and the inventor of the first
working calculating machine had reasons for faith Like Des-
cartes he was bugged by skepticism and like Descartes he ap-
pealed to human nature as a place to start the discussion

Philosophy in Only Seven Sentences
Our last sentence is not as well known as the previous ones
but it opens a door of inquiry for us
Te greatest hazard of all losing onersquos self can occur very
quietly in the world as if it were nothing at all
It was penned by an idiosyncratic and famously melancholy
Dane named Soslashren Kierkegaard a philosopher intensely inter-
ested in the self in relation to ultimate reality Tis should sound
familiar since all philosophers have expressed this interest inone way or another But Kierkegaardrsquos way was in a sense as
much psychological as philosophical He intrepidly limned the
inner workings of the self of consciousness in philosophical
categories Like Pascal Kierkegaard wanted to strip away
through existential analysis the layers and dynamics of the self
that keep reality at bay Unlike Pascal and the other philosophers
he was more interested in the analysis of the self than presentingit with arguments for an abstract objective reality Tis may
sound a bit unphilosophical but it is not But that takes time to
tease out properly as I hope you will see
Our seven sentences may be viewed as several doors into
worlds previously unknown Or they may be our irritants to
prod us to move away from facile factoidsmdashldquoDo your own thingrdquoldquoFollow your blissrdquo ldquoKeep Calm and Carry Onrdquomdashto more so-
bering reflections9 Perhaps the sentences are bridges to other
lands of thought Tese philosophical sentences do not sum the
thought of any of the philosophers for these thinkers are far too
deep for that Nor do the seven sentences aim to summarize the
history of philosophy Tat would be a pompous and laughable
claim Some things cannot be put into a nutshell including thenutshell itself But I claim that philosophical activity can be
sparked by just seven sterling sentencesmdashand who knows where
it might lead

Greeks could do philosophy Te basic questions of exis-
tence have never been far from the human mind but the
ancient Greeks excelled at this and their musingsmdashsome frag-
mentary or secondhandmdashhave been preserved in written texts
However much philosophy occurred in exclusively oral cultures
the Greeks valued writing in addition to oral memory and tra-
dition Socrates you remember wrote nothing but generated a vast literature though his dialogues A lesser-known figure who
came after him did write a few things and his famous adage is
worth considering
Protagoras (fifth century BC) is not to be confused with
like-sounding ancient Greek thinkers named Pythagoras or
Parmenides who along with others were pre-Socratic thinkers
(Tis shows the significance of Socrates since philosophy isdated with respect to his life) Tese thinkers are worth inter-
rogating as well and I studied them with profit in a year-long
course in ancient philosophy forty years ago Protagoras

stands out to us though because of his adage about absolute
assessment
Man is the measure of all things of the things which are
that they are and of things which are not that they are not1
His claim is not simply that people measure thingsmdashsuch as
character chariots boats and fishmdashbut that each human is the
measure Each person is the assessment or judgment What
could this mean No person is a slide ruler or scale or Geigercounter although we avail ourselves of such things
W I M
We tend to think that people use a standard of measurement
outside of themselves Even inadequate and one-dimensional
measures such as onersquos IQ score are not determined by how we
feel about themmdashand Mensa is very picky about thisOn the other hand Protagoras has Shakespearersquos Hamlet on
his side at least concerning morality ldquoFor there is nothing either
good or bad but thinking makes it sordquo2 Tat is morals do not
have objective standing rather they are judged differently by
different people Tis quote is from a discussion about Denmark
which Hamlet unlike his interlocutor Rosencrantz said was ldquoaprisonrdquo If Hamlet is right then both Hamlet and Rosencrantz
are right about Denmark
What then was Protagorasrsquos point (Wersquoll put serious Shake-
spearian interpretation aside) o find out we need to take a step
back into the Greek philosophical scene and not rush to
judgmentmdashor rush to endorsement either Protagoras would ap-
prove of this deliberationProtagoras was considered the chief of the Sophists intellec-
tuals who were paid to defend the views of their sponsors Tey
were accomplished orators as well as thinkers Originally the

term sophist meant something like our ldquoprofessorrdquo but later a
Sophist was deemed a hired gun a philosopher for hire and one
having no principles of his own Teir arguments supposedly
were merely the instruments of the will of their bosses One may
argue over the virtues of the Sophists but it is certainly not true
that being paid for philosophizing necessarily disqualifies the
employeersquos arguments On the other hand if we think of a
Sophist as something like a political speech writer or the like
our judgment will change Whatever the intellectual rectitudeof Protagoras he was a perpetual lecturer who articulated and
debated ideas in the marketplace a marketplace of ideas that yet
exists We may join in the discussion

Protagoras was one of a spirited group of fastidious thinkers
who tired or at least grew skeptical of Greek mythology with
its pantheon of gods Yes the stories of the gods were often riv-
eting and worth repeating A recent volume by Luc Ferry is
called Te Wisdom of the Myths How Greek Mythology Can
Change Your Life3 Tere was always a moral to the story Her-
cules the last son of Zeus was a dashing and dramatic character
who started as a mighty mortal and became a god upon deathAlthough a bit impetuous and lacking in sobriety he plays well
as a hero Zeus himself is the apotheosis of power but acts
largely without moral authority Even the might of Zeus does not
support the idea that ldquomight makes rightrdquo since might may make
for divine mischief My point is not to survey or psychoanalyze
the denizens of Greek mythology but to make a general point
Mythologies may inspire and guide to some extent our relation
to the hard facts of family life death and sexuality (and some of
the gods tended to be naughty in this way)
Nevertheless the problem with Greek mythology (or any

mythology Eastern or Western) is simply that it is mythology it
is neither history nor clearly articulated philosophy In too many
ways the gods despite their thespian reacutesumeacutes and magical
powers were not much more than semi- glorified mortals Tis
was the objection of a growing group of Greeks who were mere
mortalsmdashmortals with meaning metaphysics and morality on
their minds And what might the mind do when free to explore
life and its questions apart from the venerable stories of Greek
fascination It might philosophize and so it didProtagoras and his cohorts quested for explanations of a more
abstract but also compelling sort than the old tales could afford
Tey sought principles to explain facts in a universal and logi-
cally coherent manner o be a little unfair to the mythologies
consider the tooth fairy She adds some magical benevolence to
the loss and placement of a baby tooth for children but the fairy
story adds nothing about the nature of benevolence the signifi-
cance of teeth or the significance of the humans who grow and
lose these teeth whether through development (teething) or
decay (the toothless)
Tus to give one example Tales of Miletus tried to find a
cosmic commonality to all things He divined it as water Yes
water which was more than rain oceans lakes and puddles Itwas everywhere so perhaps it was the root and branch of every-
thing Water or moisture in general lives in the clouds in plants
in animals (aquatic land or amphibious) and in thirsty mortals
It condenses and evaporates but never leaves the planet Con-
sidering the presence and power of water Tales extrapolated
that water was more than one more thing on earth however
necessary for life It was rather the unifying principle for exis-
tence Whatever we think of Tales his thinking is not absurd
and it indicates a thirst for philosophical explanation as opposed
to mythological meanderings At least he was trying

But it is Protagoras who calls for our attention Instead of ar-guing for something at the heart of everything (water for Tales)
a principle found in nature Protagoras moved back from nature
to the self After all skeptics had questioned mere mortalsrsquo
ability to know with any confidence what is out there inde-
pendent of themselves Te jaundiced eye sees things differently
from the nonjaundiced eye Children perceive entities invisible
to adults Adults sometimes hallucinatemdashbut perhaps they areseeing what most miss One woman feels cold in a room of degF
and another feels hot Age alters hearing seeing memory and
may jangle judgments Te upshot is that we cannot find a place
to stand to see the world as it is We are simply ill-equipped to
do so Objective truth what is independent of our perceptions
endlessly and mercilessly eludes us
We will return to skepticism when discussing Descartes and
Pascal but Protagoras was not a skeptic He did not withhold
judgments about facts in themselves because we do not have the
ability to know them While recognizing that the skeptics had
dethroned our intellectual confidence in capturing objective re-
ality his point of departure was this we do know our own view-
points judgments and beliefs Tat is we measure things theydo not measure themselves So I take most of Francis Baconrsquos
paintings to be ugly and thus unattractive I am repulsed Tis is
the end of the story or my story Tis is my measurement You
on the contrary may find delight in Baconrsquos tortured figures and
color schemes Tat is your measurement and the end of your
story
Now reconsider the skeptical point made earlier One person
can deem the room cold and another hot Te skeptic might say
we cannot know then what the room is given the variability in
perception But Protagoras claims that the room is hot for person

I will come to adore Baconrsquos paintings and heap scorn on my
former judgment If so then that is my measurement

of Protagorasrsquos statement ldquoMan is the measure of all thingsrdquomdash
matters of taste as well as matters of fact matters of principle
and matters of matter Nothing is excluded
Let us follow this out As we think it through the old Greek
will sound much like modern man If Protagoras is right then
there is no disputing matters of morality either Man is the
measure of what is right and what is wrong what is virtuous and
what is vicious what should be loved and what should be hatedmdash
just as Hamlet claimed oday this thinking is usually put in thelanguage of choice instead of measurement but the idea is the
same If you chose to do X that choice is the end of the matter
Or to suit Protagoras if you measure X as worth doing then it
is worth doing Tis is true whether X refers to sailing stealing
or stampeding cattle in the direction of a Cub Scout outing
But we might say ldquoWho is to judgerdquo Who of us can stand
above him- or herself and others and become objective Yes we
recoil from some ideasmdashsuch as torturing the innocent merely
for pleasure or female genital mutilation But what does that tell
us about reality if there really is such a thing as reality Te claim

Protagoras
that ldquoman is the measure of all thingsrdquo is an all-encompassing
judgment itself Te answer to ldquoWho is to judgerdquo is that we are
the measure of all things Tat is there is nothing outside of
human judgment by which it might be judged But why would
Protagoras (or anyone else) consider that to be reality itself

Besides being a serial killer ed Bundy was a philosophical
thinker of the Protagorean type Remarkably his philosophy wascaught on tape before he raped and killed a young woman She
was one of dozens of his prey As reported in Louis Pojmanrsquos text
Moral Philosophy Bundy said
I learned that all moral judgments are ldquovalue judgmentsrdquo
that all value judgments are subjective and that none can
be proved to be either ldquorightrdquo or ldquowrongrdquo I even read some-where that the Chief Justice of the United States had written
that the American Constitution expressed nothing more
than collective value judgments Believe it or not I figured
out for myselfmdashwhat apparently the Chief Justice couldnrsquot
figure out for himselfmdashthat if the rationality of one value
judgment was zero multiplying it by millions would not
make it one whit more rational Nor is there any ldquoreasonrdquo
to obey the law for anyone like myself who has the
boldness and daring ldquothe strength of characterrdquo to throw
off its shackles
I discovered that to become truly free truly unfettered
I had to become truly uninhibited And I quickly discovered
that the greatest obstacle to my freedom the greatest blockand limitation to it consists in the insupportable ldquovalue

When teaching ethics to undergraduates at a secular school I
often hand out this Bundy quotation but without identifying the
speaker I then ask them to write a paragraph on whether they
agree with its basic idea Most students approve of the unknown

philosophy of one of the most infamous serial killers in American
historymdashthe philosophy that allowed and even impelled hisegregious crimes Next I ask them to reconsider their judg-

on this basis But a statement cannot be true unless it accords

of the food I am the measure of that at least It matters nothing
whether a connoisseur thinks me an ignoramus I can only
measure it by what I experience at the moment In that way I am

Teaetetus Protagoras even states that error is impossible5 Al-
though he was a teacher he cannot by his own lights teach
anyone o this Socrates inquires
If whatever the individual judges by means of perception is
true for him if no man can assess anotherrsquos experiencebetter than he or can claim authority to examine another
manrsquos judgment and see if it be right or wrong if as we
have repeatedly said only the individual himself can judge
of his own world and what he judges is always true and

was a wise man so wise as to think himself fit to be the
teacher of other men and worth large fees while we in
comparison with him the ignorant ones needed to go and
sit at his feetmdashwe who are ourselves each the measure of
his own wisdom6

be written in Chinese or in English Since each language uses
different symbols for writing its graphic inscription for cat will
differ Tis is true for voicing the word cat as well Trough a
long messy process not instigated by any central planning each
culture selects its own conventions of communication Are not
these two systems of writing measuring reality in very different
ways In point of fact they are not
Both kinds of writing systems (as well as other means ofcommunication) make claims about a reality that are outside
of the systems themselves and outside of the individuals who
use the pictographic or ideographic methods We tacitly saw
this earlier But in both cases a cat is invoked there is a single
referent Te differences in linguistic custom are not differ-
ences in content A cat is a cat in whatever language and it will
not bark however it may be measured Moreover while it may
be vexing in places one can translate a book from English to
Chinese Not everything is lost in translation in fact more is
found than is lost ranslators need have no fear of losing their
livelihood
Staying on matters of taste for a moment (and not morality

reading when you were quite young Tey are likely not the
same as when you became an adult You may still enjoy and
laugh at nursery rhymes but your tastes have expanded Yes
you still love Winnie the Pooh (and I mean the original Pooh
not the Walt Disney version) but you understand and appre-

pectedly) childish Te apostle Paul notes this in a well-known
turn of phrase ldquoWhen I was a child I talked like a child I
thought like a child I reasoned like a child When I became a
man I put the ways of childhood behind merdquo ( Corinthians
see also Hebrews -)
Furthermore the very notion of improvement or progress
(not merely some change in quality) requires and assumes an
objective standard by which to measure improvement (or de-cline) If a baseball batter hits in and in he
has improved based on the best possible average of Tere
is a measurement and it is not the perception of the batter that
determines this measurement Tis is the case in the arts as well
Few knowledgeable about jazz would dispute that John Col-
tranersquos saxophone work improved during his tenure with pianist
Telonious Monkrsquos quartet or that it developed further in Col-
trane own ldquoclassic quartetrdquo (ndash)7 Here the assessment is
not quantitative or statistical but qualitative One might object
that this is a purely subjective judgment (such as whether one
feels hot or not) which is relative to the person hearing Who is
to judge Te answer is straightforward the one whose expe-
rience knowledge and wisdom merit approval Although manydrink wine there are few expert wine tasters A student of mine
is so adept at this art that he can tell what part of the country a
wine came from Not having developed this advanced degree of
skill this is foreign to me However I had no inclination to say
that my judgment on wine is as accurate as Markrsquos Along these
lines I was once embarrassed when one of my students told me
that the wine I was enjoying was ldquothe Kenny G of winesrdquo Tis as
jazz aficionados know was not a compliment about the wine or
about my taste for wine
Artistic judgments involve much more than my quick treatment

But Herodotus may yet rescue Protagoras In his History the
ancient historian notes that Darius a king of ancient Persia (who
was a kind of premodern anthropologist because of his study of
cultural differences) called together some Greeks and askedthem what it would take to cannibalize their dead fathers Te
Greeks needed no time to ponder the proposition since nothing
would move them to such odious paternal desecration Teir
practice was cremation this alone would honor their dead Ten
Darius summoned several Callatians (from India) to join the
Greeks and asked them what would make them cremate their
deceased fathers Te Callatians were as horrified as the Greeks
had been and told Darius to not discuss such atrocities
Had Protagoras heard this he would likely applaud having
found more evidence for his outlook But not all applause is
earned While the Greeks and Callatians observed fundamen-
tally different funeral rites both cultures honored the dead Tat
is only particular practicesmdashnot just any old or new thingmdashwere esteemed right and good in the treatment of corpses and
these practices were not norms for the treatment of the living
In other words death was set apart as uniquely meaningful and
thus required that the living treat the dead with ritual respect
Tus Greeks and Callatians agreed on a deep principle of hon-
oring the dead Tey disagreed on the rule that stems from that
principle In no sense then does the example of cultural rela-
tivity disprove moral agreement across cultures since there was
deep agreement between the cultures C S Lewis makes just
this point in Mere Christianity

Protagoras
I know that some people say the idea of a Law of Nature or
decent behaviour known to all men is unsound because
different civilisations and different ages have had quite dif-
ferent moralities
But this is not true Tere have been differences between
their moralities but these have never amounted to any-
thing like a total difference If anyone will take the trouble
to compare the moral teaching of say the ancient Egyp-
tians Babylonians Hindus Chinese Greeks and Romanswhat will really strike him will be how very like they are to
each other and to our own9
Te case against Protagoras comes down to this If we want to
learn anything if we want to improve as human beings if we
want to condemn the ed Bundys of the world if we want any
kind of educated taste if we desire to understand and honorhumanity then we must reject the ldquoman is the measurerdquo theory
Each person is indeed the measurer of some things Some of
them the individual gets right some of them the individual gets
wrong And in this difference lies all the difference in the world
and even outside of it

Introduction
PHILOSOPHY IN ONLY
SEVEN SENTENCES
Can we tackle some of the key questions and answers in
philosophy through just seven sentences by seven famous
philosophers I wager we can so we will Many other sentencesmdash
or paragraphs or booksmdashcould have made the cut Because of
this some will argue that my selection was biased ignorant or
slanted If so let them philosophize over it After all that is the
purpose of this book to think and act philosophically
I make no claim that Philosophy in Seven Sentences is repre-
sentative of philosophy as a whole I chose these authors and
their sentences for several reasons First I was familiar with
them As I point out several times many of these ideas havedeep autobiographical significance to me Second they raise
issues pertinent to our day Tird each sentence is fairly well
known none is esoteric1 I also chose these authors because
their arguments were clear enough to be well suited to philo-
sophical analysis even on a popular level2
Some may think that popular philosophy is an oxymoron a
silly contradiction not worthy of a momentrsquos thought Phi-losophy is of course for expertsmdashthose who have accumulated
vast student-loan debts after which they have logged long and
lonely years in the classroom studying at their desks and ar-

guing with other philosophers about philosophy Tese strange
souls are abstruse esoteric recondite and many other long
pompous words not meant for the masses Philosophers write
for each other argue with each other and often flummox or bore
the hapless college students whose academic requirements put
them in their presence
And so it is for many philosophers but not for all of them At
its most ancient root philosophy was meant to initiate us into
ldquothe good liferdquo to tutor us for the ongoing experience ofknowledge and virtue Since everyone lives some kind of life
philosophy explored the mindrsquos abilities to live life in accord
with reality At best it helps scratch the itch of human exis-
tencemdashor at its worst it rubs the wound raw Even though ety-
mology (the study of word origins) may deceive it does its work
well in understanding the origin of philosophy telling us that
its two Greek parts are love ( philos) and wisdom ( sophos) Phi-
losophers may not always love wisdom but that is their disci-
plinersquos pedigree Te Hebrew Bible warns in the book of
Proverbs that both wisdom and folly call out for reflection and
allegiance Te wise are diligent in learning facing the facts in
earnest while the fool sacrifices character for ignorance and
untutored pleasure But knowledge beckons nevertheless atleast in our better moments As Aristotle wrote ldquoAll men by
nature desire to knowrdquo (We will examine this sentence shortly)
Any thinking person may join philosophyrsquos discussion which
rings down through the ages Tat is the aim of this small book
which I hope can be read profitably by both philosophical neo-
phytes and seasoned philosophers whatever their worldview
may be My aims are catholic (universal) however parochial my
selections may seem to some
Philosophy is not a closed club or a secret society Since we
all can think about ultimate questions letrsquos do it For the record

Philosophy in Only Seven Sentences
I propose that the requirements for being a philosopher (whether
good or bad major or minor professional or layperson) are a
strong and lived-out inclination to pursue truth through the rig-
orous use of human reasoning and to do so with some intel-
lectual facility But sadly even some philosophers disavow the
search for truth In Whatrsquos the Use of ruth French philosopher
Pascal Engel writes ldquoTere is no obligation to say or to be-
lieve that which is truerdquo3 If so why should we read his writings
or those of any other philosopherIs then everyone a philosopher Everyone muses a bit on
where we came from who we are and where we are going But
not all do this very well So while Johnny Rotten (b ) of the
Sex Pistols addressed some philosophical themes in his punk
rock compositions and performances one is reluctant to give
him the title of philosopher Tis is because it is a kind of merit
badge reserved for the few I was recently asked by a precocious
ten-year-old named Liam if I was a philosopher I said I was

about argumentsrdquo We then discussed the nature of an argument
With a little coaxing he told me what an argument was giving
reasons for what you believe often in conversations with those
who believe otherwise I have recruited him for graduate studyin my program
o enjoin the discussion of philosophy I will appeal to seven
sentences all of which are short but none of which are trivial
Some are more renowned than others A few of them are famous
Tese statements are not impenetrable deceiving the unwary
inquirer with obscurity masquerading as profundity Sadly not
a few philosophers cloak their ideas with idiosyncrasies and un-
necessary jargon Not so for a Socrates or Jesus who went about
speaking the common tongue in uncommon ways to both

ideas are affirmed and denied by the simplest and most sophis-

nature of truth how we gain knowledge the meaning of humanexistence death the source of morality and more In my many
years as a teacher and learner of this antique art I find to my

Protagoras is not a household name Google him and find out(Te first entry is not surprisingly Wikipedia) Nor do you find
many academic titles analyzing his ideas although he is often
grouped with the Sophists Tis is considered a disreputable
crowd by some wags and is even a byword ldquoYou sophistrdquo Te
charge is that Sophists cared nothing for truth but cared every-
thing about being paid to philosophize for a vested interest
More on these philosophers-for-hire later Even so this oldGreek crystallizes the thought of not a few philosophers and
nonphilosophers Our chosen sentence sums it up
Man is the measure of all things of the things which are
that they are and of things which are not that they are not6
Protagoras gives wings to an idea that many ponder try our
hardest (or not try at all) we cannot break free of ourselvesmdashour
senses our viewpoints our values even our ldquostuffrdquo Te world is
our judgment and nothing more It does not await our judgment
it is our judgment Tere is no objective truth but only various
views from various places at various times by various people
Tings are not our measure but we are the measure of them
Hence Protagoras is the spokesman for relativism sometimescalled nonrealism or perspectivism It is not just that we have no
(or limited) access to objective reality Tat is skepticism Reality
is pretty much exhausted by our perceptions and thoughts Te
real world is our world Myriads have measured Protagoras

wisdom can ignore him His ghost haunts us still Is there a phil-

students to live this waymdashfor their sakes and mine (It makes for
better papers too) Tus said Socrates the gadfly (or pain-in-
the-neck) of ancient Athens Like Protagoras we know of
Socrates through those who knew his work but unlike Pro-
tagoras we have more substantial sources particularly Plato
And Socrates is a household name Not incidentally the man
who was not an author ended up being the inspiration for the
prolific Plato who was the worldrsquos first systematic philosopher
As philosopher Alfred North Whitehead discerned ldquoTe safestgeneral characterization of the European philosophical tradition
is that it consists of a series of footnotes to Platordquo7 Te footnotes
may praise (Augustine) or blame (Aristotle) but footnotes are
everywhere as well as entire volumes
aking up Socratesrsquos philosophical challenge means exam-
ining just what his famous sentence means in itself and what it
means for us What might an examined life be given the distrac-
tions and overstimulation of postmodern times For Socrates
there is a way to calm the mind and search things out But is
there a place for Socratic dialogue today outside the Socratic
method of many law schools Further old Plato Socratesrsquos
chronicler and student may offer us wisdom pertaining to the
nagging questions of philosophy as he spurns the work of the philodoxers (lovers of opinion) and promotes the call of the phi-
losophers (lovers of wisdom) Worse yet were the misologists (one
of the Platonic corpusrsquos most winning words) those who took an
active role in hating the use of reason itself We may find some
today even in educated enclaves or even on the bestsellers lists
But one can also find Aristotle in popular bookstores always
in the philosophy section (along with less prestigious volumes
such as Led Zeppelin and Philosophy which we must pass over
without further comment) When Aristotle wrote ldquoAll men by
nature desire to knowrdquo he did not mean just the scholars or

teachers but ldquomanrdquomdashthe human race in all its circumstances and
variations Tat means every person whatever social standing
vocation or intelligence Although Aristotle was no egalitarian
(he thought that women were inferior to men and that some were
born to be slaves) he nevertheless appeals to a universal human
condition the desire to get reality right in the time that we have
Augustine the first great Christian philosopher like Socrates
before him strikes a personal note concerning getting reality
right Having examined himself and the leading philosophies ofhis day (including Plato and his footnotes) he confesses with a
cry of the heart addressed to God ldquoYou have made us for
yourself and restless is our heart until it comes to rest in yourdquo
Tis cry is not commonplace as in ldquoMy spirituality gives me
meaningrdquo It is instead the beginning of an argument told in his
autobiography In fact it may be the first autobiography on
record It is no doubt the first philosophical autobiography (if
we exclude the book of Ecclesiastes) Te irascible Jean-Jacques
Rousseau is well known for his autobiography as well but a short
book can only do so much8
Skipping madly over much philosophical history (without any
irreverence or glibness) we arrive at Reneacute Descartes the much
maligned but seldom understood ldquofather of modern philosophyrdquoDescartes was troubled by opinions without backingmdashthose
ideas about ultimate matters untethered from certainty Skep-
ticism was his foe as it is in one way or another for any philos-
opher Tis is because the question arises How do you know
what you claim to know Mere social position or historical tra-
dition will not cinch the deal for this philosopher and scientist
In our language (which itself needs interrogation) the man
ldquowanted proofrdquo While ldquoI donrsquot knowrdquo is often the most knowl-
edgeable answer it should not be the default response according
to Descartes Tis apprehension led him on a quest that began

with himself Like Augustine but in briefer scope he put this in
autobiographical form in Discourse on Method and to some
extent in Meditations on First Philosophy But Descartesrsquos quest
did not end with himself unlike so much contemporary self-
help literature He is famous for the sentence ldquoI think therefore
I amrdquo But God himself has something to do with that sentence
For Descartes there was no leap of faith in it either Reason was
the guide But how far can reason take us
A contemporary of Descartes had an idea ldquoTe heart has itsreasons that reason knows nothing ofrdquo wrote Blaise Pascal who
was the best phrasemaker of the lot of our philosophers Tis
statement is a window into a worldview Humans have the ca-
pacity to calculate and reason methodically but they may also
know some things by tracing out the contours and resources of
ldquothe heartrdquomdashanother organ of knowledge Philosophers study
many thinkers but few come to love few of them (My graduate
seminar on Kantrsquos Critique of Pure Reason was well worth it but
was no love affair) Pascal on the contrary is much loved by many
He is so loved that people even love things he never actually said
such as ldquoTere is a God-shaped vacuum that only God can fillrdquo
But this paraphrase is not far off the mark though it should be
placed within a larger perspective of Pascalrsquos philosophyTe French polymathrsquos philosophy is far more fascinating than
the CliffsNotes version allows Pascal did not put faith in place
of reason and he was not a one-trick philosopher (Pascalrsquos
wager) Slander and libel have fouled the air about him ob-
scuring his sophisticated treatment of the cost-benefit sense of
believing in religion or not Yet he was neither knave nor poser
Te founder of probability theory and the inventor of the first
working calculating machine had reasons for faith Like Des-
cartes he was bugged by skepticism and like Descartes he ap-
pealed to human nature as a place to start the discussion

quietly in the world as if it were nothing at all
It was penned by an idiosyncratic and famously melancholy
Dane named Soslashren Kierkegaard a philosopher intensely inter-
ested in the self in relation to ultimate reality Tis should sound
familiar since all philosophers have expressed this interest inone way or another But Kierkegaardrsquos way was in a sense as
much psychological as philosophical He intrepidly limned the
inner workings of the self of consciousness in philosophical
categories Like Pascal Kierkegaard wanted to strip away
through existential analysis the layers and dynamics of the self
that keep reality at bay Unlike Pascal and the other philosophers
he was more interested in the analysis of the self than presentingit with arguments for an abstract objective reality Tis may
sound a bit unphilosophical but it is not But that takes time to
tease out properly as I hope you will see
Our seven sentences may be viewed as several doors into
worlds previously unknown Or they may be our irritants to
prod us to move away from facile factoidsmdashldquoDo your own thingrdquoldquoFollow your blissrdquo ldquoKeep Calm and Carry Onrdquomdashto more so-
bering reflections9 Perhaps the sentences are bridges to other
lands of thought Tese philosophical sentences do not sum the
thought of any of the philosophers for these thinkers are far too
deep for that Nor do the seven sentences aim to summarize the
history of philosophy Tat would be a pompous and laughable
claim Some things cannot be put into a nutshell including thenutshell itself But I claim that philosophical activity can be
sparked by just seven sterling sentencesmdashand who knows where
it might lead

PROTAGORAS
Man is the measure of all things
P
Greeks could do philosophy Te basic questions of exis-
tence have never been far from the human mind but the
ancient Greeks excelled at this and their musingsmdashsome frag-
mentary or secondhandmdashhave been preserved in written texts
However much philosophy occurred in exclusively oral cultures
the Greeks valued writing in addition to oral memory and tra-
dition Socrates you remember wrote nothing but generated a vast literature though his dialogues A lesser-known figure who
came after him did write a few things and his famous adage is
worth considering
Protagoras (fifth century BC) is not to be confused with
like-sounding ancient Greek thinkers named Pythagoras or
Parmenides who along with others were pre-Socratic thinkers
(Tis shows the significance of Socrates since philosophy isdated with respect to his life) Tese thinkers are worth inter-
rogating as well and I studied them with profit in a year-long
course in ancient philosophy forty years ago Protagoras

stands out to us though because of his adage about absolute
assessment
Man is the measure of all things of the things which are
that they are and of things which are not that they are not1
His claim is not simply that people measure thingsmdashsuch as
character chariots boats and fishmdashbut that each human is the
measure Each person is the assessment or judgment What
could this mean No person is a slide ruler or scale or Geigercounter although we avail ourselves of such things
W I M
We tend to think that people use a standard of measurement
outside of themselves Even inadequate and one-dimensional
measures such as onersquos IQ score are not determined by how we
feel about themmdashand Mensa is very picky about thisOn the other hand Protagoras has Shakespearersquos Hamlet on
his side at least concerning morality ldquoFor there is nothing either
good or bad but thinking makes it sordquo2 Tat is morals do not
have objective standing rather they are judged differently by
different people Tis quote is from a discussion about Denmark
which Hamlet unlike his interlocutor Rosencrantz said was ldquoaprisonrdquo If Hamlet is right then both Hamlet and Rosencrantz
are right about Denmark
What then was Protagorasrsquos point (Wersquoll put serious Shake-
spearian interpretation aside) o find out we need to take a step
back into the Greek philosophical scene and not rush to
judgmentmdashor rush to endorsement either Protagoras would ap-
prove of this deliberationProtagoras was considered the chief of the Sophists intellec-
tuals who were paid to defend the views of their sponsors Tey
were accomplished orators as well as thinkers Originally the

term sophist meant something like our ldquoprofessorrdquo but later a
Sophist was deemed a hired gun a philosopher for hire and one
having no principles of his own Teir arguments supposedly
were merely the instruments of the will of their bosses One may
argue over the virtues of the Sophists but it is certainly not true
that being paid for philosophizing necessarily disqualifies the
employeersquos arguments On the other hand if we think of a
Sophist as something like a political speech writer or the like
our judgment will change Whatever the intellectual rectitudeof Protagoras he was a perpetual lecturer who articulated and
debated ideas in the marketplace a marketplace of ideas that yet
exists We may join in the discussion

Protagoras was one of a spirited group of fastidious thinkers
who tired or at least grew skeptical of Greek mythology with
its pantheon of gods Yes the stories of the gods were often riv-
eting and worth repeating A recent volume by Luc Ferry is
called Te Wisdom of the Myths How Greek Mythology Can
Change Your Life3 Tere was always a moral to the story Her-
cules the last son of Zeus was a dashing and dramatic character
who started as a mighty mortal and became a god upon deathAlthough a bit impetuous and lacking in sobriety he plays well
as a hero Zeus himself is the apotheosis of power but acts
largely without moral authority Even the might of Zeus does not
support the idea that ldquomight makes rightrdquo since might may make
for divine mischief My point is not to survey or psychoanalyze
the denizens of Greek mythology but to make a general point
Mythologies may inspire and guide to some extent our relation
to the hard facts of family life death and sexuality (and some of
the gods tended to be naughty in this way)
Nevertheless the problem with Greek mythology (or any

mythology Eastern or Western) is simply that it is mythology it
is neither history nor clearly articulated philosophy In too many
ways the gods despite their thespian reacutesumeacutes and magical
powers were not much more than semi- glorified mortals Tis
was the objection of a growing group of Greeks who were mere
mortalsmdashmortals with meaning metaphysics and morality on
their minds And what might the mind do when free to explore
life and its questions apart from the venerable stories of Greek
fascination It might philosophize and so it didProtagoras and his cohorts quested for explanations of a more
abstract but also compelling sort than the old tales could afford
Tey sought principles to explain facts in a universal and logi-
cally coherent manner o be a little unfair to the mythologies
consider the tooth fairy She adds some magical benevolence to
the loss and placement of a baby tooth for children but the fairy
story adds nothing about the nature of benevolence the signifi-
cance of teeth or the significance of the humans who grow and
lose these teeth whether through development (teething) or
decay (the toothless)
Tus to give one example Tales of Miletus tried to find a
cosmic commonality to all things He divined it as water Yes
water which was more than rain oceans lakes and puddles Itwas everywhere so perhaps it was the root and branch of every-
thing Water or moisture in general lives in the clouds in plants
in animals (aquatic land or amphibious) and in thirsty mortals
It condenses and evaporates but never leaves the planet Con-
sidering the presence and power of water Tales extrapolated
that water was more than one more thing on earth however
necessary for life It was rather the unifying principle for exis-
tence Whatever we think of Tales his thinking is not absurd
and it indicates a thirst for philosophical explanation as opposed
to mythological meanderings At least he was trying

Protagoras

But it is Protagoras who calls for our attention Instead of ar-guing for something at the heart of everything (water for Tales)
a principle found in nature Protagoras moved back from nature
to the self After all skeptics had questioned mere mortalsrsquo
ability to know with any confidence what is out there inde-
pendent of themselves Te jaundiced eye sees things differently
from the nonjaundiced eye Children perceive entities invisible
to adults Adults sometimes hallucinatemdashbut perhaps they areseeing what most miss One woman feels cold in a room of degF
and another feels hot Age alters hearing seeing memory and
may jangle judgments Te upshot is that we cannot find a place
to stand to see the world as it is We are simply ill-equipped to
do so Objective truth what is independent of our perceptions
endlessly and mercilessly eludes us
We will return to skepticism when discussing Descartes and
Pascal but Protagoras was not a skeptic He did not withhold
judgments about facts in themselves because we do not have the
ability to know them While recognizing that the skeptics had
dethroned our intellectual confidence in capturing objective re-
ality his point of departure was this we do know our own view-
points judgments and beliefs Tat is we measure things theydo not measure themselves So I take most of Francis Baconrsquos
paintings to be ugly and thus unattractive I am repulsed Tis is
the end of the story or my story Tis is my measurement You
on the contrary may find delight in Baconrsquos tortured figures and
color schemes Tat is your measurement and the end of your
story
Now reconsider the skeptical point made earlier One person
can deem the room cold and another hot Te skeptic might say
we cannot know then what the room is given the variability in
perception But Protagoras claims that the room is hot for person

A and not hot for person B Tere is no contradiction since we
are considering individual perceptions Tere are two measure-
ments each of which is valid Tus Bacon is barbaric to me and
beautiful to youmdashand that is the level best we can do Or perhaps
I will come to adore Baconrsquos paintings and heap scorn on my
former judgment If so then that is my measurement
Tis is rather attractive at first blush After all there is no
dispute in matters of taste or to be more snobby De gustibus
non est disputandum Te avant-garde saxophone playing ofPeter Broumltzmann can send me into the upper reaches of aes-
thetic delight while sending others scurrying from the room
while covering their ears But Protagoras took this insight far
beyond artistic judgments Notice the reference range (or extent)
of Protagorasrsquos statement ldquoMan is the measure of all thingsrdquomdash
matters of taste as well as matters of fact matters of principle
and matters of matter Nothing is excluded
Let us follow this out As we think it through the old Greek
will sound much like modern man If Protagoras is right then
there is no disputing matters of morality either Man is the
measure of what is right and what is wrong what is virtuous and
what is vicious what should be loved and what should be hatedmdash
just as Hamlet claimed oday this thinking is usually put in thelanguage of choice instead of measurement but the idea is the
same If you chose to do X that choice is the end of the matter
Or to suit Protagoras if you measure X as worth doing then it
is worth doing Tis is true whether X refers to sailing stealing
or stampeding cattle in the direction of a Cub Scout outing
But we might say ldquoWho is to judgerdquo Who of us can stand
above him- or herself and others and become objective Yes we
recoil from some ideasmdashsuch as torturing the innocent merely
for pleasure or female genital mutilation But what does that tell
us about reality if there really is such a thing as reality Te claim

that ldquoman is the measure of all thingsrdquo is an all-encompassing
judgment itself Te answer to ldquoWho is to judgerdquo is that we are
the measure of all things Tat is there is nothing outside of
human judgment by which it might be judged But why would
Protagoras (or anyone else) consider that to be reality itself

Besides being a serial killer ed Bundy was a philosophical
thinker of the Protagorean type Remarkably his philosophy wascaught on tape before he raped and killed a young woman She
was one of dozens of his prey As reported in Louis Pojmanrsquos text
Moral Philosophy Bundy said
I learned that all moral judgments are ldquovalue judgmentsrdquo
that all value judgments are subjective and that none can
be proved to be either ldquorightrdquo or ldquowrongrdquo I even read some-where that the Chief Justice of the United States had written
that the American Constitution expressed nothing more
than collective value judgments Believe it or not I figured
out for myselfmdashwhat apparently the Chief Justice couldnrsquot
figure out for himselfmdashthat if the rationality of one value
judgment was zero multiplying it by millions would not
make it one whit more rational Nor is there any ldquoreasonrdquo
to obey the law for anyone like myself who has the
boldness and daring ldquothe strength of characterrdquo to throw
off its shackles
I discovered that to become truly free truly unfettered
I had to become truly uninhibited And I quickly discovered
that the greatest obstacle to my freedom the greatest blockand limitation to it consists in the insupportable ldquovalue

Why should I be willing to sacrifice my pleasure more for
the one than for the other Surely you would not in this
age of scientific enlightenment declare that God or nature
has marked some pleasures as ldquomoralrdquo or ldquogoodrdquo and others
as ldquoimmoralrdquo or ldquobadrdquo4
When teaching ethics to undergraduates at a secular school I
often hand out this Bundy quotation but without identifying the
speaker I then ask them to write a paragraph on whether they
agree with its basic idea Most students approve of the unknown
authorrsquos sentiments I then reveal that this statement was the
philosophy of one of the most infamous serial killers in American
historymdashthe philosophy that allowed and even impelled hisegregious crimes Next I ask them to reconsider their judg-
ments Te results are usually mixed but the majority of stu-
dents show dismay and surprise that they were in agreement
with a view that justified serial rape and murder

us and nothing beneath us It is all merely neutral and we make
the callmdashon everything ldquoMan is the measure of all thingsrdquoSo then what does this sentence tell us about philosophy and

existentially Tey often capture some truth and so seduce us
on this basis But a statement cannot be true unless it accords
with the way the world in fact is and the way we in fact are Pro-
tagoras does capture some truths about perspective For ex-
ample my tastes in food determine how I measure the goodness
of the food I am the measure of that at least It matters nothing
whether a connoisseur thinks me an ignoramus I can only
measure it by what I experience at the moment In that way I am
the measure but am I the expert Am I the knowerTere is a strange implication for Protagorasrsquos view In the
Teaetetus Protagoras even states that error is impossible5 Al-
though he was a teacher he cannot by his own lights teach
anyone o this Socrates inquires
If whatever the individual judges by means of perception is
true for him if no man can assess anotherrsquos experiencebetter than he or can claim authority to examine another
manrsquos judgment and see if it be right or wrong if as we
have repeatedly said only the individual himself can judge
of his own world and what he judges is always true and
correct how could it ever be my friend that Protagoras
was a wise man so wise as to think himself fit to be the
teacher of other men and worth large fees while we in
comparison with him the ignorant ones needed to go and
sit at his feetmdashwe who are ourselves each the measure of
his own wisdom6

human languages For example the general concept of cat may
be written in Chinese or in English Since each language uses
different symbols for writing its graphic inscription for cat will
differ Tis is true for voicing the word cat as well Trough a
long messy process not instigated by any central planning each
culture selects its own conventions of communication Are not
these two systems of writing measuring reality in very different
ways In point of fact they are not
Both kinds of writing systems (as well as other means ofcommunication) make claims about a reality that are outside
of the systems themselves and outside of the individuals who
use the pictographic or ideographic methods We tacitly saw
this earlier But in both cases a cat is invoked there is a single
referent Te differences in linguistic custom are not differ-
ences in content A cat is a cat in whatever language and it will
not bark however it may be measured Moreover while it may
be vexing in places one can translate a book from English to
Chinese Not everything is lost in translation in fact more is
found than is lost ranslators need have no fear of losing their
livelihood
Staying on matters of taste for a moment (and not morality
for now) are all people equally skilled in measurement Tepoet and literary critic S Eliot advocated the cultivation of
ldquoeducated tasterdquo Consider your preferences in music and
reading when you were quite young Tey are likely not the
same as when you became an adult You may still enjoy and
laugh at nursery rhymes but your tastes have expanded Yes
you still love Winnie the Pooh (and I mean the original Pooh
not the Walt Disney version) but you understand and appre-
ciate it more deeply now If so (and substitute your own ex-
amples here if needed) your tastes have at least changed and
have likely improved with age Your earlier judgments were

likely age appropriate but they were limited and (not unex-
pectedly) childish Te apostle Paul notes this in a well-known
turn of phrase ldquoWhen I was a child I talked like a child I
thought like a child I reasoned like a child When I became a
man I put the ways of childhood behind merdquo ( Corinthians
see also Hebrews -)
Furthermore the very notion of improvement or progress
(not merely some change in quality) requires and assumes an
objective standard by which to measure improvement (or de-cline) If a baseball batter hits in and in he
has improved based on the best possible average of Tere
is a measurement and it is not the perception of the batter that
determines this measurement Tis is the case in the arts as well
Few knowledgeable about jazz would dispute that John Col-
tranersquos saxophone work improved during his tenure with pianist
Telonious Monkrsquos quartet or that it developed further in Col-
trane own ldquoclassic quartetrdquo (ndash)7 Here the assessment is
not quantitative or statistical but qualitative One might object
that this is a purely subjective judgment (such as whether one
feels hot or not) which is relative to the person hearing Who is
to judge Te answer is straightforward the one whose expe-
rience knowledge and wisdom merit approval Although manydrink wine there are few expert wine tasters A student of mine
is so adept at this art that he can tell what part of the country a
wine came from Not having developed this advanced degree of
skill this is foreign to me However I had no inclination to say
that my judgment on wine is as accurate as Markrsquos Along these
lines I was once embarrassed when one of my students told me
that the wine I was enjoying was ldquothe Kenny G of winesrdquo Tis as
jazz aficionados know was not a compliment about the wine or
about my taste for wine

I have not even given clear aesthetic criteria8 My point is that
beauty is not only in the eye of the beholder If not we are haunted

But Herodotus may yet rescue Protagoras In his History the
ancient historian notes that Darius a king of ancient Persia (who
was a kind of premodern anthropologist because of his study of
cultural differences) called together some Greeks and askedthem what it would take to cannibalize their dead fathers Te
Greeks needed no time to ponder the proposition since nothing
would move them to such odious paternal desecration Teir
practice was cremation this alone would honor their dead Ten
Darius summoned several Callatians (from India) to join the
Greeks and asked them what would make them cremate their
deceased fathers Te Callatians were as horrified as the Greeks
had been and told Darius to not discuss such atrocities
Had Protagoras heard this he would likely applaud having
found more evidence for his outlook But not all applause is
earned While the Greeks and Callatians observed fundamen-
tally different funeral rites both cultures honored the dead Tat
is only particular practicesmdashnot just any old or new thingmdashwere esteemed right and good in the treatment of corpses and
these practices were not norms for the treatment of the living
In other words death was set apart as uniquely meaningful and
thus required that the living treat the dead with ritual respect
Tus Greeks and Callatians agreed on a deep principle of hon-
oring the dead Tey disagreed on the rule that stems from that
principle In no sense then does the example of cultural rela-
tivity disprove moral agreement across cultures since there was
deep agreement between the cultures C S Lewis makes just
this point in Mere Christianity

Protagoras
I know that some people say the idea of a Law of Nature or
decent behaviour known to all men is unsound because
different civilisations and different ages have had quite dif-
ferent moralities
But this is not true Tere have been differences between
their moralities but these have never amounted to any-
thing like a total difference If anyone will take the trouble
to compare the moral teaching of say the ancient Egyp-
tians Babylonians Hindus Chinese Greeks and Romanswhat will really strike him will be how very like they are to
each other and to our own9
Te case against Protagoras comes down to this If we want to
learn anything if we want to improve as human beings if we
want to condemn the ed Bundys of the world if we want any
kind of educated taste if we desire to understand and honorhumanity then we must reject the ldquoman is the measurerdquo theory
Each person is indeed the measurer of some things Some of
them the individual gets right some of them the individual gets
wrong And in this difference lies all the difference in the world

Introduction
PHILOSOPHY IN ONLY
SEVEN SENTENCES
Can we tackle some of the key questions and answers in
philosophy through just seven sentences by seven famous
philosophers I wager we can so we will Many other sentencesmdash
or paragraphs or booksmdashcould have made the cut Because of
this some will argue that my selection was biased ignorant or
slanted If so let them philosophize over it After all that is the
purpose of this book to think and act philosophically
I make no claim that Philosophy in Seven Sentences is repre-
sentative of philosophy as a whole I chose these authors and
their sentences for several reasons First I was familiar with
them As I point out several times many of these ideas havedeep autobiographical significance to me Second they raise
issues pertinent to our day Tird each sentence is fairly well
known none is esoteric1 I also chose these authors because
their arguments were clear enough to be well suited to philo-
sophical analysis even on a popular level2
Some may think that popular philosophy is an oxymoron a
silly contradiction not worthy of a momentrsquos thought Phi-losophy is of course for expertsmdashthose who have accumulated
vast student-loan debts after which they have logged long and
lonely years in the classroom studying at their desks and ar-

guing with other philosophers about philosophy Tese strange
souls are abstruse esoteric recondite and many other long
pompous words not meant for the masses Philosophers write
for each other argue with each other and often flummox or bore
the hapless college students whose academic requirements put
them in their presence
And so it is for many philosophers but not for all of them At
its most ancient root philosophy was meant to initiate us into
ldquothe good liferdquo to tutor us for the ongoing experience ofknowledge and virtue Since everyone lives some kind of life
philosophy explored the mindrsquos abilities to live life in accord
with reality At best it helps scratch the itch of human exis-
tencemdashor at its worst it rubs the wound raw Even though ety-
mology (the study of word origins) may deceive it does its work
well in understanding the origin of philosophy telling us that
its two Greek parts are love ( philos) and wisdom ( sophos) Phi-
losophers may not always love wisdom but that is their disci-
plinersquos pedigree Te Hebrew Bible warns in the book of
Proverbs that both wisdom and folly call out for reflection and
allegiance Te wise are diligent in learning facing the facts in
earnest while the fool sacrifices character for ignorance and
untutored pleasure But knowledge beckons nevertheless atleast in our better moments As Aristotle wrote ldquoAll men by
nature desire to knowrdquo (We will examine this sentence shortly)
Any thinking person may join philosophyrsquos discussion which
rings down through the ages Tat is the aim of this small book
which I hope can be read profitably by both philosophical neo-
phytes and seasoned philosophers whatever their worldview
may be My aims are catholic (universal) however parochial my
selections may seem to some
Philosophy is not a closed club or a secret society Since we
all can think about ultimate questions letrsquos do it For the record

Philosophy in Only Seven Sentences
I propose that the requirements for being a philosopher (whether
good or bad major or minor professional or layperson) are a
strong and lived-out inclination to pursue truth through the rig-
orous use of human reasoning and to do so with some intel-
lectual facility But sadly even some philosophers disavow the
search for truth In Whatrsquos the Use of ruth French philosopher
Pascal Engel writes ldquoTere is no obligation to say or to be-
lieve that which is truerdquo3 If so why should we read his writings
or those of any other philosopherIs then everyone a philosopher Everyone muses a bit on
where we came from who we are and where we are going But
not all do this very well So while Johnny Rotten (b ) of the
Sex Pistols addressed some philosophical themes in his punk
rock compositions and performances one is reluctant to give
him the title of philosopher Tis is because it is a kind of merit
badge reserved for the few I was recently asked by a precocious
ten-year-old named Liam if I was a philosopher I said I was
Ten he asked ldquoWhat do you dordquo My reply was ldquoI think a lot
about argumentsrdquo We then discussed the nature of an argument
With a little coaxing he told me what an argument was giving
reasons for what you believe often in conversations with those
who believe otherwise I have recruited him for graduate studyin my program
o enjoin the discussion of philosophy I will appeal to seven
sentences all of which are short but none of which are trivial
Some are more renowned than others A few of them are famous
Tese statements are not impenetrable deceiving the unwary
inquirer with obscurity masquerading as profundity Sadly not
a few philosophers cloak their ideas with idiosyncrasies and un-
necessary jargon Not so for a Socrates or Jesus who went about
speaking the common tongue in uncommon ways to both
common and uncommon people Te public square was their

classroom and all comers were their students Neither wrote a
word but their words are unforgettable as we will see Teir
ideas are affirmed and denied by the simplest and most sophis-
ticated thinkers
While we cannot directly encounter the likes of Socrates or
Jesusmdashor the more bookish philosophers such as Plato Aris-
totle Augustine Descartes and kindredmdashwe can interrogate
them and investigate the perennial questions they address the
nature of truth how we gain knowledge the meaning of humanexistence death the source of morality and more In my many
years as a teacher and learner of this antique art I find to my
dismay that too many students too often give up too soon Tey
face an intellectual difficulty some demanding reading or differ-
ences of opinion and they cash in their chips despite my provo-
cations cajoling and (on occasion) anger It need not be and
should not be so S Eliot should kindle a flame in us ldquoBut our

Protagoras is not a household name Google him and find out(Te first entry is not surprisingly Wikipedia) Nor do you find
many academic titles analyzing his ideas although he is often
grouped with the Sophists Tis is considered a disreputable
crowd by some wags and is even a byword ldquoYou sophistrdquo Te
charge is that Sophists cared nothing for truth but cared every-
thing about being paid to philosophize for a vested interest
More on these philosophers-for-hire later Even so this oldGreek crystallizes the thought of not a few philosophers and
nonphilosophers Our chosen sentence sums it up
Man is the measure of all things of the things which are
that they are and of things which are not that they are not6
Protagoras gives wings to an idea that many ponder try our
hardest (or not try at all) we cannot break free of ourselvesmdashour
senses our viewpoints our values even our ldquostuffrdquo Te world is
our judgment and nothing more It does not await our judgment
it is our judgment Tere is no objective truth but only various
views from various places at various times by various people
Tings are not our measure but we are the measure of them
Hence Protagoras is the spokesman for relativism sometimescalled nonrealism or perspectivism It is not just that we have no
(or limited) access to objective reality Tat is skepticism Reality
is pretty much exhausted by our perceptions and thoughts Te
real world is our world Myriads have measured Protagoras
wrong at least on this but no one in pursuit of knowledge and
wisdom can ignore him His ghost haunts us still Is there a phil-
osophical exorcist aboutOur next sentence is often heard but seldom digested I un-

students to live this waymdashfor their sakes and mine (It makes for
better papers too) Tus said Socrates the gadfly (or pain-in-
the-neck) of ancient Athens Like Protagoras we know of
Socrates through those who knew his work but unlike Pro-
tagoras we have more substantial sources particularly Plato
And Socrates is a household name Not incidentally the man
who was not an author ended up being the inspiration for the
prolific Plato who was the worldrsquos first systematic philosopher
As philosopher Alfred North Whitehead discerned ldquoTe safestgeneral characterization of the European philosophical tradition
is that it consists of a series of footnotes to Platordquo7 Te footnotes
may praise (Augustine) or blame (Aristotle) but footnotes are
everywhere as well as entire volumes
aking up Socratesrsquos philosophical challenge means exam-
ining just what his famous sentence means in itself and what it
means for us What might an examined life be given the distrac-
tions and overstimulation of postmodern times For Socrates
there is a way to calm the mind and search things out But is
there a place for Socratic dialogue today outside the Socratic
method of many law schools Further old Plato Socratesrsquos
chronicler and student may offer us wisdom pertaining to the
nagging questions of philosophy as he spurns the work of the philodoxers (lovers of opinion) and promotes the call of the phi-
losophers (lovers of wisdom) Worse yet were the misologists (one
of the Platonic corpusrsquos most winning words) those who took an
active role in hating the use of reason itself We may find some
today even in educated enclaves or even on the bestsellers lists
But one can also find Aristotle in popular bookstores always
in the philosophy section (along with less prestigious volumes
such as Led Zeppelin and Philosophy which we must pass over
without further comment) When Aristotle wrote ldquoAll men by
nature desire to knowrdquo he did not mean just the scholars or

teachers but ldquomanrdquomdashthe human race in all its circumstances and
variations Tat means every person whatever social standing
vocation or intelligence Although Aristotle was no egalitarian
(he thought that women were inferior to men and that some were
born to be slaves) he nevertheless appeals to a universal human
condition the desire to get reality right in the time that we have
Augustine the first great Christian philosopher like Socrates
before him strikes a personal note concerning getting reality
right Having examined himself and the leading philosophies ofhis day (including Plato and his footnotes) he confesses with a
cry of the heart addressed to God ldquoYou have made us for
yourself and restless is our heart until it comes to rest in yourdquo
Tis cry is not commonplace as in ldquoMy spirituality gives me
meaningrdquo It is instead the beginning of an argument told in his
autobiography In fact it may be the first autobiography on
record It is no doubt the first philosophical autobiography (if
we exclude the book of Ecclesiastes) Te irascible Jean-Jacques
Rousseau is well known for his autobiography as well but a short
book can only do so much8
Skipping madly over much philosophical history (without any
irreverence or glibness) we arrive at Reneacute Descartes the much
maligned but seldom understood ldquofather of modern philosophyrdquoDescartes was troubled by opinions without backingmdashthose
ideas about ultimate matters untethered from certainty Skep-
ticism was his foe as it is in one way or another for any philos-
opher Tis is because the question arises How do you know
what you claim to know Mere social position or historical tra-
dition will not cinch the deal for this philosopher and scientist
In our language (which itself needs interrogation) the man
ldquowanted proofrdquo While ldquoI donrsquot knowrdquo is often the most knowl-
edgeable answer it should not be the default response according
to Descartes Tis apprehension led him on a quest that began

with himself Like Augustine but in briefer scope he put this in
autobiographical form in Discourse on Method and to some
extent in Meditations on First Philosophy But Descartesrsquos quest
did not end with himself unlike so much contemporary self-
help literature He is famous for the sentence ldquoI think therefore
I amrdquo But God himself has something to do with that sentence
For Descartes there was no leap of faith in it either Reason was
the guide But how far can reason take us
A contemporary of Descartes had an idea ldquoTe heart has itsreasons that reason knows nothing ofrdquo wrote Blaise Pascal who
was the best phrasemaker of the lot of our philosophers Tis
statement is a window into a worldview Humans have the ca-
pacity to calculate and reason methodically but they may also
know some things by tracing out the contours and resources of
ldquothe heartrdquomdashanother organ of knowledge Philosophers study
many thinkers but few come to love few of them (My graduate
seminar on Kantrsquos Critique of Pure Reason was well worth it but
was no love affair) Pascal on the contrary is much loved by many
He is so loved that people even love things he never actually said
such as ldquoTere is a God-shaped vacuum that only God can fillrdquo
But this paraphrase is not far off the mark though it should be
placed within a larger perspective of Pascalrsquos philosophyTe French polymathrsquos philosophy is far more fascinating than
the CliffsNotes version allows Pascal did not put faith in place
of reason and he was not a one-trick philosopher (Pascalrsquos
wager) Slander and libel have fouled the air about him ob-
scuring his sophisticated treatment of the cost-benefit sense of
believing in religion or not Yet he was neither knave nor poser
Te founder of probability theory and the inventor of the first
working calculating machine had reasons for faith Like Des-
cartes he was bugged by skepticism and like Descartes he ap-
pealed to human nature as a place to start the discussion

Our last sentence is not as well known as the previous ones
but it opens a door of inquiry for us
Te greatest hazard of all losing onersquos self can occur very
quietly in the world as if it were nothing at all
It was penned by an idiosyncratic and famously melancholy
Dane named Soslashren Kierkegaard a philosopher intensely inter-
ested in the self in relation to ultimate reality Tis should sound
familiar since all philosophers have expressed this interest inone way or another But Kierkegaardrsquos way was in a sense as
much psychological as philosophical He intrepidly limned the
inner workings of the self of consciousness in philosophical
categories Like Pascal Kierkegaard wanted to strip away
through existential analysis the layers and dynamics of the self
that keep reality at bay Unlike Pascal and the other philosophers
he was more interested in the analysis of the self than presentingit with arguments for an abstract objective reality Tis may
sound a bit unphilosophical but it is not But that takes time to
tease out properly as I hope you will see
Our seven sentences may be viewed as several doors into
worlds previously unknown Or they may be our irritants to
prod us to move away from facile factoidsmdashldquoDo your own thingrdquoldquoFollow your blissrdquo ldquoKeep Calm and Carry Onrdquomdashto more so-
bering reflections9 Perhaps the sentences are bridges to other
lands of thought Tese philosophical sentences do not sum the
thought of any of the philosophers for these thinkers are far too
deep for that Nor do the seven sentences aim to summarize the
history of philosophy Tat would be a pompous and laughable
claim Some things cannot be put into a nutshell including thenutshell itself But I claim that philosophical activity can be
sparked by just seven sterling sentencesmdashand who knows where
it might lead

PROTAGORAS
Man is the measure of all things
P
Greeks could do philosophy Te basic questions of exis-
tence have never been far from the human mind but the
ancient Greeks excelled at this and their musingsmdashsome frag-
mentary or secondhandmdashhave been preserved in written texts
However much philosophy occurred in exclusively oral cultures
the Greeks valued writing in addition to oral memory and tra-
dition Socrates you remember wrote nothing but generated a vast literature though his dialogues A lesser-known figure who
came after him did write a few things and his famous adage is
worth considering
Protagoras (fifth century BC) is not to be confused with
like-sounding ancient Greek thinkers named Pythagoras or
Parmenides who along with others were pre-Socratic thinkers
(Tis shows the significance of Socrates since philosophy isdated with respect to his life) Tese thinkers are worth inter-
rogating as well and I studied them with profit in a year-long
course in ancient philosophy forty years ago Protagoras

stands out to us though because of his adage about absolute
assessment
Man is the measure of all things of the things which are
that they are and of things which are not that they are not1
His claim is not simply that people measure thingsmdashsuch as
character chariots boats and fishmdashbut that each human is the
measure Each person is the assessment or judgment What
could this mean No person is a slide ruler or scale or Geigercounter although we avail ourselves of such things
W I M
We tend to think that people use a standard of measurement
outside of themselves Even inadequate and one-dimensional
measures such as onersquos IQ score are not determined by how we
feel about themmdashand Mensa is very picky about thisOn the other hand Protagoras has Shakespearersquos Hamlet on
his side at least concerning morality ldquoFor there is nothing either
good or bad but thinking makes it sordquo2 Tat is morals do not
have objective standing rather they are judged differently by
different people Tis quote is from a discussion about Denmark
which Hamlet unlike his interlocutor Rosencrantz said was ldquoaprisonrdquo If Hamlet is right then both Hamlet and Rosencrantz
are right about Denmark
What then was Protagorasrsquos point (Wersquoll put serious Shake-
spearian interpretation aside) o find out we need to take a step
back into the Greek philosophical scene and not rush to
judgmentmdashor rush to endorsement either Protagoras would ap-
prove of this deliberationProtagoras was considered the chief of the Sophists intellec-
tuals who were paid to defend the views of their sponsors Tey
were accomplished orators as well as thinkers Originally the

term sophist meant something like our ldquoprofessorrdquo but later a
Sophist was deemed a hired gun a philosopher for hire and one
having no principles of his own Teir arguments supposedly
were merely the instruments of the will of their bosses One may
argue over the virtues of the Sophists but it is certainly not true
that being paid for philosophizing necessarily disqualifies the
employeersquos arguments On the other hand if we think of a
Sophist as something like a political speech writer or the like
our judgment will change Whatever the intellectual rectitudeof Protagoras he was a perpetual lecturer who articulated and
debated ideas in the marketplace a marketplace of ideas that yet

Protagoras was one of a spirited group of fastidious thinkers
who tired or at least grew skeptical of Greek mythology with
its pantheon of gods Yes the stories of the gods were often riv-
eting and worth repeating A recent volume by Luc Ferry is
called Te Wisdom of the Myths How Greek Mythology Can
Change Your Life3 Tere was always a moral to the story Her-
cules the last son of Zeus was a dashing and dramatic character
who started as a mighty mortal and became a god upon deathAlthough a bit impetuous and lacking in sobriety he plays well
as a hero Zeus himself is the apotheosis of power but acts
largely without moral authority Even the might of Zeus does not
support the idea that ldquomight makes rightrdquo since might may make
for divine mischief My point is not to survey or psychoanalyze
the denizens of Greek mythology but to make a general point
Mythologies may inspire and guide to some extent our relation
to the hard facts of family life death and sexuality (and some of
the gods tended to be naughty in this way)
Nevertheless the problem with Greek mythology (or any

mythology Eastern or Western) is simply that it is mythology it
is neither history nor clearly articulated philosophy In too many
ways the gods despite their thespian reacutesumeacutes and magical
powers were not much more than semi- glorified mortals Tis
was the objection of a growing group of Greeks who were mere
mortalsmdashmortals with meaning metaphysics and morality on
their minds And what might the mind do when free to explore
life and its questions apart from the venerable stories of Greek
fascination It might philosophize and so it didProtagoras and his cohorts quested for explanations of a more
abstract but also compelling sort than the old tales could afford
Tey sought principles to explain facts in a universal and logi-
cally coherent manner o be a little unfair to the mythologies
consider the tooth fairy She adds some magical benevolence to
the loss and placement of a baby tooth for children but the fairy
story adds nothing about the nature of benevolence the signifi-
cance of teeth or the significance of the humans who grow and
lose these teeth whether through development (teething) or
decay (the toothless)
Tus to give one example Tales of Miletus tried to find a
cosmic commonality to all things He divined it as water Yes
water which was more than rain oceans lakes and puddles Itwas everywhere so perhaps it was the root and branch of every-
thing Water or moisture in general lives in the clouds in plants
in animals (aquatic land or amphibious) and in thirsty mortals
It condenses and evaporates but never leaves the planet Con-
sidering the presence and power of water Tales extrapolated
that water was more than one more thing on earth however
necessary for life It was rather the unifying principle for exis-
tence Whatever we think of Tales his thinking is not absurd
and it indicates a thirst for philosophical explanation as opposed
to mythological meanderings At least he was trying

But it is Protagoras who calls for our attention Instead of ar-guing for something at the heart of everything (water for Tales)
a principle found in nature Protagoras moved back from nature
to the self After all skeptics had questioned mere mortalsrsquo
ability to know with any confidence what is out there inde-
pendent of themselves Te jaundiced eye sees things differently
from the nonjaundiced eye Children perceive entities invisible
to adults Adults sometimes hallucinatemdashbut perhaps they areseeing what most miss One woman feels cold in a room of degF
and another feels hot Age alters hearing seeing memory and
may jangle judgments Te upshot is that we cannot find a place
to stand to see the world as it is We are simply ill-equipped to
do so Objective truth what is independent of our perceptions
endlessly and mercilessly eludes us
We will return to skepticism when discussing Descartes and
Pascal but Protagoras was not a skeptic He did not withhold
judgments about facts in themselves because we do not have the
ability to know them While recognizing that the skeptics had
dethroned our intellectual confidence in capturing objective re-
ality his point of departure was this we do know our own view-
points judgments and beliefs Tat is we measure things theydo not measure themselves So I take most of Francis Baconrsquos
paintings to be ugly and thus unattractive I am repulsed Tis is
the end of the story or my story Tis is my measurement You
on the contrary may find delight in Baconrsquos tortured figures and
color schemes Tat is your measurement and the end of your
story
Now reconsider the skeptical point made earlier One person
can deem the room cold and another hot Te skeptic might say
we cannot know then what the room is given the variability in
perception But Protagoras claims that the room is hot for person

A and not hot for person B Tere is no contradiction since we
are considering individual perceptions Tere are two measure-
ments each of which is valid Tus Bacon is barbaric to me and
beautiful to youmdashand that is the level best we can do Or perhaps
I will come to adore Baconrsquos paintings and heap scorn on my
former judgment If so then that is my measurement
Tis is rather attractive at first blush After all there is no
dispute in matters of taste or to be more snobby De gustibus
non est disputandum Te avant-garde saxophone playing ofPeter Broumltzmann can send me into the upper reaches of aes-
thetic delight while sending others scurrying from the room
while covering their ears But Protagoras took this insight far
beyond artistic judgments Notice the reference range (or extent)
of Protagorasrsquos statement ldquoMan is the measure of all thingsrdquomdash
matters of taste as well as matters of fact matters of principle
and matters of matter Nothing is excluded
Let us follow this out As we think it through the old Greek
will sound much like modern man If Protagoras is right then
there is no disputing matters of morality either Man is the
measure of what is right and what is wrong what is virtuous and
what is vicious what should be loved and what should be hatedmdash
just as Hamlet claimed oday this thinking is usually put in thelanguage of choice instead of measurement but the idea is the
same If you chose to do X that choice is the end of the matter
Or to suit Protagoras if you measure X as worth doing then it
is worth doing Tis is true whether X refers to sailing stealing
or stampeding cattle in the direction of a Cub Scout outing
But we might say ldquoWho is to judgerdquo Who of us can stand
above him- or herself and others and become objective Yes we
recoil from some ideasmdashsuch as torturing the innocent merely
for pleasure or female genital mutilation But what does that tell
us about reality if there really is such a thing as reality Te claim

that ldquoman is the measure of all thingsrdquo is an all-encompassing
judgment itself Te answer to ldquoWho is to judgerdquo is that we are

human judgment by which it might be judged But why would

I learned that all moral judgments are ldquovalue judgmentsrdquo
that all value judgments are subjective and that none can
be proved to be either ldquorightrdquo or ldquowrongrdquo I even read some-where that the Chief Justice of the United States had written
that the American Constitution expressed nothing more
than collective value judgments Believe it or not I figured
out for myselfmdashwhat apparently the Chief Justice couldnrsquot
figure out for himselfmdashthat if the rationality of one value
judgment was zero multiplying it by millions would not
make it one whit more rational Nor is there any ldquoreasonrdquo
to obey the law for anyone like myself who has the
boldness and daring ldquothe strength of characterrdquo to throw
off its shackles
I discovered that to become truly free truly unfettered
I had to become truly uninhibited And I quickly discovered
that the greatest obstacle to my freedom the greatest blockand limitation to it consists in the insupportable ldquovalue

historymdashthe philosophy that allowed and even impelled hisegregious crimes Next I ask them to reconsider their judg-

on this basis But a statement cannot be true unless it accords
with the way the world in fact is and the way we in fact are Pro-

of the food I am the measure of that at least It matters nothing
whether a connoisseur thinks me an ignoramus I can only
measure it by what I experience at the moment In that way I am

Teaetetus Protagoras even states that error is impossible5 Al-
though he was a teacher he cannot by his own lights teach
anyone o this Socrates inquires
If whatever the individual judges by means of perception is
true for him if no man can assess anotherrsquos experiencebetter than he or can claim authority to examine another
manrsquos judgment and see if it be right or wrong if as we
have repeatedly said only the individual himself can judge
of his own world and what he judges is always true and
correct how could it ever be my friend that Protagoras
was a wise man so wise as to think himself fit to be the
teacher of other men and worth large fees while we in

sit at his feetmdashwe who are ourselves each the measure of
his own wisdom6

be written in Chinese or in English Since each language uses
different symbols for writing its graphic inscription for cat will
differ Tis is true for voicing the word cat as well Trough a
long messy process not instigated by any central planning each
culture selects its own conventions of communication Are not
these two systems of writing measuring reality in very different
ways In point of fact they are not
Both kinds of writing systems (as well as other means ofcommunication) make claims about a reality that are outside
of the systems themselves and outside of the individuals who
use the pictographic or ideographic methods We tacitly saw
this earlier But in both cases a cat is invoked there is a single
referent Te differences in linguistic custom are not differ-
ences in content A cat is a cat in whatever language and it will
not bark however it may be measured Moreover while it may

Furthermore the very notion of improvement or progress
(not merely some change in quality) requires and assumes an
objective standard by which to measure improvement (or de-cline) If a baseball batter hits in and in he
has improved based on the best possible average of Tere
is a measurement and it is not the perception of the batter that
determines this measurement Tis is the case in the arts as well
Few knowledgeable about jazz would dispute that John Col-
tranersquos saxophone work improved during his tenure with pianist
Telonious Monkrsquos quartet or that it developed further in Col-
trane own ldquoclassic quartetrdquo (ndash)7 Here the assessment is
not quantitative or statistical but qualitative One might object
that this is a purely subjective judgment (such as whether one
feels hot or not) which is relative to the person hearing Who is
to judge Te answer is straightforward the one whose expe-
rience knowledge and wisdom merit approval Although manydrink wine there are few expert wine tasters A student of mine
is so adept at this art that he can tell what part of the country a
wine came from Not having developed this advanced degree of
skill this is foreign to me However I had no inclination to say
that my judgment on wine is as accurate as Markrsquos Along these
lines I was once embarrassed when one of my students told me
that the wine I was enjoying was ldquothe Kenny G of winesrdquo Tis as

about my taste for wine

ancient historian notes that Darius a king of ancient Persia (who
was a kind of premodern anthropologist because of his study of
cultural differences) called together some Greeks and askedthem what it would take to cannibalize their dead fathers Te
Greeks needed no time to ponder the proposition since nothing
would move them to such odious paternal desecration Teir
practice was cremation this alone would honor their dead Ten
Darius summoned several Callatians (from India) to join the
Greeks and asked them what would make them cremate their
deceased fathers Te Callatians were as horrified as the Greeks
had been and told Darius to not discuss such atrocities
Had Protagoras heard this he would likely applaud having
found more evidence for his outlook But not all applause is
earned While the Greeks and Callatians observed fundamen-
tally different funeral rites both cultures honored the dead Tat
is only particular practicesmdashnot just any old or new thingmdashwere esteemed right and good in the treatment of corpses and
these practices were not norms for the treatment of the living
In other words death was set apart as uniquely meaningful and
thus required that the living treat the dead with ritual respect
Tus Greeks and Callatians agreed on a deep principle of hon-
oring the dead Tey disagreed on the rule that stems from that
principle In no sense then does the example of cultural rela-
tivity disprove moral agreement across cultures since there was
deep agreement between the cultures C S Lewis makes just
this point in Mere Christianity

Protagoras
I know that some people say the idea of a Law of Nature or
decent behaviour known to all men is unsound because
different civilisations and different ages have had quite dif-
ferent moralities
But this is not true Tere have been differences between
their moralities but these have never amounted to any-
thing like a total difference If anyone will take the trouble
to compare the moral teaching of say the ancient Egyp-
tians Babylonians Hindus Chinese Greeks and Romanswhat will really strike him will be how very like they are to
each other and to our own9
Te case against Protagoras comes down to this If we want to
learn anything if we want to improve as human beings if we
want to condemn the ed Bundys of the world if we want any
kind of educated taste if we desire to understand and honorhumanity then we must reject the ldquoman is the measurerdquo theory
Each person is indeed the measurer of some things Some of
them the individual gets right some of them the individual gets
wrong And in this difference lies all the difference in the world
and even outside of it

guing with other philosophers about philosophy Tese strange
souls are abstruse esoteric recondite and many other long
pompous words not meant for the masses Philosophers write
for each other argue with each other and often flummox or bore
the hapless college students whose academic requirements put
them in their presence
And so it is for many philosophers but not for all of them At
its most ancient root philosophy was meant to initiate us into
ldquothe good liferdquo to tutor us for the ongoing experience ofknowledge and virtue Since everyone lives some kind of life
philosophy explored the mindrsquos abilities to live life in accord
with reality At best it helps scratch the itch of human exis-
tencemdashor at its worst it rubs the wound raw Even though ety-
mology (the study of word origins) may deceive it does its work
well in understanding the origin of philosophy telling us that
its two Greek parts are love ( philos) and wisdom ( sophos) Phi-
losophers may not always love wisdom but that is their disci-
plinersquos pedigree Te Hebrew Bible warns in the book of
Proverbs that both wisdom and folly call out for reflection and
allegiance Te wise are diligent in learning facing the facts in
earnest while the fool sacrifices character for ignorance and
untutored pleasure But knowledge beckons nevertheless atleast in our better moments As Aristotle wrote ldquoAll men by
nature desire to knowrdquo (We will examine this sentence shortly)
Any thinking person may join philosophyrsquos discussion which
rings down through the ages Tat is the aim of this small book
which I hope can be read profitably by both philosophical neo-
phytes and seasoned philosophers whatever their worldview
may be My aims are catholic (universal) however parochial my
selections may seem to some
Philosophy is not a closed club or a secret society Since we
all can think about ultimate questions letrsquos do it For the record

Philosophy in Only Seven Sentences
I propose that the requirements for being a philosopher (whether
good or bad major or minor professional or layperson) are a
strong and lived-out inclination to pursue truth through the rig-
orous use of human reasoning and to do so with some intel-
lectual facility But sadly even some philosophers disavow the
search for truth In Whatrsquos the Use of ruth French philosopher
Pascal Engel writes ldquoTere is no obligation to say or to be-
lieve that which is truerdquo3 If so why should we read his writings
or those of any other philosopherIs then everyone a philosopher Everyone muses a bit on
where we came from who we are and where we are going But
not all do this very well So while Johnny Rotten (b ) of the
Sex Pistols addressed some philosophical themes in his punk
rock compositions and performances one is reluctant to give
him the title of philosopher Tis is because it is a kind of merit
badge reserved for the few I was recently asked by a precocious
ten-year-old named Liam if I was a philosopher I said I was

about argumentsrdquo We then discussed the nature of an argument

nature of truth how we gain knowledge the meaning of humanexistence death the source of morality and more In my many

Protagoras is not a household name Google him and find out(Te first entry is not surprisingly Wikipedia) Nor do you find
many academic titles analyzing his ideas although he is often
grouped with the Sophists Tis is considered a disreputable
crowd by some wags and is even a byword ldquoYou sophistrdquo Te
charge is that Sophists cared nothing for truth but cared every-
thing about being paid to philosophize for a vested interest
More on these philosophers-for-hire later Even so this oldGreek crystallizes the thought of not a few philosophers and
nonphilosophers Our chosen sentence sums it up
Man is the measure of all things of the things which are
that they are and of things which are not that they are not6
Protagoras gives wings to an idea that many ponder try our
hardest (or not try at all) we cannot break free of ourselvesmdashour
senses our viewpoints our values even our ldquostuffrdquo Te world is
our judgment and nothing more It does not await our judgment
it is our judgment Tere is no objective truth but only various
views from various places at various times by various people
Tings are not our measure but we are the measure of them
Hence Protagoras is the spokesman for relativism sometimescalled nonrealism or perspectivism It is not just that we have no
(or limited) access to objective reality Tat is skepticism Reality
is pretty much exhausted by our perceptions and thoughts Te
real world is our world Myriads have measured Protagoras
wrong at least on this but no one in pursuit of knowledge and
wisdom can ignore him His ghost haunts us still Is there a phil-

students to live this waymdashfor their sakes and mine (It makes for
better papers too) Tus said Socrates the gadfly (or pain-in-
the-neck) of ancient Athens Like Protagoras we know of
Socrates through those who knew his work but unlike Pro-
tagoras we have more substantial sources particularly Plato
And Socrates is a household name Not incidentally the man
who was not an author ended up being the inspiration for the
prolific Plato who was the worldrsquos first systematic philosopher
As philosopher Alfred North Whitehead discerned ldquoTe safestgeneral characterization of the European philosophical tradition
is that it consists of a series of footnotes to Platordquo7 Te footnotes
may praise (Augustine) or blame (Aristotle) but footnotes are
everywhere as well as entire volumes
aking up Socratesrsquos philosophical challenge means exam-
ining just what his famous sentence means in itself and what it
means for us What might an examined life be given the distrac-
tions and overstimulation of postmodern times For Socrates
there is a way to calm the mind and search things out But is
there a place for Socratic dialogue today outside the Socratic
method of many law schools Further old Plato Socratesrsquos
chronicler and student may offer us wisdom pertaining to the
nagging questions of philosophy as he spurns the work of the philodoxers (lovers of opinion) and promotes the call of the phi-
losophers (lovers of wisdom) Worse yet were the misologists (one
of the Platonic corpusrsquos most winning words) those who took an
active role in hating the use of reason itself We may find some
today even in educated enclaves or even on the bestsellers lists
But one can also find Aristotle in popular bookstores always
in the philosophy section (along with less prestigious volumes
such as Led Zeppelin and Philosophy which we must pass over
without further comment) When Aristotle wrote ldquoAll men by
nature desire to knowrdquo he did not mean just the scholars or

teachers but ldquomanrdquomdashthe human race in all its circumstances and
variations Tat means every person whatever social standing
vocation or intelligence Although Aristotle was no egalitarian
(he thought that women were inferior to men and that some were
born to be slaves) he nevertheless appeals to a universal human
condition the desire to get reality right in the time that we have
Augustine the first great Christian philosopher like Socrates
before him strikes a personal note concerning getting reality
right Having examined himself and the leading philosophies ofhis day (including Plato and his footnotes) he confesses with a
cry of the heart addressed to God ldquoYou have made us for
yourself and restless is our heart until it comes to rest in yourdquo
Tis cry is not commonplace as in ldquoMy spirituality gives me
meaningrdquo It is instead the beginning of an argument told in his
autobiography In fact it may be the first autobiography on
record It is no doubt the first philosophical autobiography (if
we exclude the book of Ecclesiastes) Te irascible Jean-Jacques
Rousseau is well known for his autobiography as well but a short
book can only do so much8
Skipping madly over much philosophical history (without any
irreverence or glibness) we arrive at Reneacute Descartes the much
maligned but seldom understood ldquofather of modern philosophyrdquoDescartes was troubled by opinions without backingmdashthose
ideas about ultimate matters untethered from certainty Skep-
ticism was his foe as it is in one way or another for any philos-
opher Tis is because the question arises How do you know
what you claim to know Mere social position or historical tra-
dition will not cinch the deal for this philosopher and scientist
In our language (which itself needs interrogation) the man

edgeable answer it should not be the default response according
to Descartes Tis apprehension led him on a quest that began

with himself Like Augustine but in briefer scope he put this in
autobiographical form in Discourse on Method and to some
extent in Meditations on First Philosophy But Descartesrsquos quest
did not end with himself unlike so much contemporary self-
help literature He is famous for the sentence ldquoI think therefore
I amrdquo But God himself has something to do with that sentence
For Descartes there was no leap of faith in it either Reason was
the guide But how far can reason take us
A contemporary of Descartes had an idea ldquoTe heart has itsreasons that reason knows nothing ofrdquo wrote Blaise Pascal who
was the best phrasemaker of the lot of our philosophers Tis
statement is a window into a worldview Humans have the ca-
pacity to calculate and reason methodically but they may also
know some things by tracing out the contours and resources of
ldquothe heartrdquomdashanother organ of knowledge Philosophers study
many thinkers but few come to love few of them (My graduate
seminar on Kantrsquos Critique of Pure Reason was well worth it but
was no love affair) Pascal on the contrary is much loved by many
He is so loved that people even love things he never actually said
such as ldquoTere is a God-shaped vacuum that only God can fillrdquo
But this paraphrase is not far off the mark though it should be
placed within a larger perspective of Pascalrsquos philosophyTe French polymathrsquos philosophy is far more fascinating than
the CliffsNotes version allows Pascal did not put faith in place
of reason and he was not a one-trick philosopher (Pascalrsquos
wager) Slander and libel have fouled the air about him ob-
scuring his sophisticated treatment of the cost-benefit sense of
believing in religion or not Yet he was neither knave nor poser
Te founder of probability theory and the inventor of the first
working calculating machine had reasons for faith Like Des-
cartes he was bugged by skepticism and like Descartes he ap-
pealed to human nature as a place to start the discussion

Philosophy in Only Seven Sentences
Our last sentence is not as well known as the previous ones
but it opens a door of inquiry for us
Te greatest hazard of all losing onersquos self can occur very
quietly in the world as if it were nothing at all
It was penned by an idiosyncratic and famously melancholy
Dane named Soslashren Kierkegaard a philosopher intensely inter-
ested in the self in relation to ultimate reality Tis should sound
familiar since all philosophers have expressed this interest inone way or another But Kierkegaardrsquos way was in a sense as
much psychological as philosophical He intrepidly limned the
inner workings of the self of consciousness in philosophical
categories Like Pascal Kierkegaard wanted to strip away
through existential analysis the layers and dynamics of the self
that keep reality at bay Unlike Pascal and the other philosophers
he was more interested in the analysis of the self than presentingit with arguments for an abstract objective reality Tis may
sound a bit unphilosophical but it is not But that takes time to
tease out properly as I hope you will see
Our seven sentences may be viewed as several doors into
worlds previously unknown Or they may be our irritants to
prod us to move away from facile factoidsmdashldquoDo your own thingrdquoldquoFollow your blissrdquo ldquoKeep Calm and Carry Onrdquomdashto more so-
bering reflections9 Perhaps the sentences are bridges to other
lands of thought Tese philosophical sentences do not sum the
thought of any of the philosophers for these thinkers are far too
deep for that Nor do the seven sentences aim to summarize the
history of philosophy Tat would be a pompous and laughable
claim Some things cannot be put into a nutshell including thenutshell itself But I claim that philosophical activity can be
sparked by just seven sterling sentencesmdashand who knows where
it might lead

Man is the measure of all things
P
Greeks could do philosophy Te basic questions of exis-
tence have never been far from the human mind but the
ancient Greeks excelled at this and their musingsmdashsome frag-
mentary or secondhandmdashhave been preserved in written texts
However much philosophy occurred in exclusively oral cultures
the Greeks valued writing in addition to oral memory and tra-
dition Socrates you remember wrote nothing but generated a vast literature though his dialogues A lesser-known figure who
came after him did write a few things and his famous adage is
worth considering
Protagoras (fifth century BC) is not to be confused with
like-sounding ancient Greek thinkers named Pythagoras or
Parmenides who along with others were pre-Socratic thinkers
(Tis shows the significance of Socrates since philosophy isdated with respect to his life) Tese thinkers are worth inter-
rogating as well and I studied them with profit in a year-long
course in ancient philosophy forty years ago Protagoras

stands out to us though because of his adage about absolute
assessment
Man is the measure of all things of the things which are
that they are and of things which are not that they are not1
His claim is not simply that people measure thingsmdashsuch as
character chariots boats and fishmdashbut that each human is the
measure Each person is the assessment or judgment What
could this mean No person is a slide ruler or scale or Geigercounter although we avail ourselves of such things
W I M
We tend to think that people use a standard of measurement
outside of themselves Even inadequate and one-dimensional
measures such as onersquos IQ score are not determined by how we
feel about themmdashand Mensa is very picky about thisOn the other hand Protagoras has Shakespearersquos Hamlet on
his side at least concerning morality ldquoFor there is nothing either
good or bad but thinking makes it sordquo2 Tat is morals do not
have objective standing rather they are judged differently by
different people Tis quote is from a discussion about Denmark
which Hamlet unlike his interlocutor Rosencrantz said was ldquoaprisonrdquo If Hamlet is right then both Hamlet and Rosencrantz
are right about Denmark
What then was Protagorasrsquos point (Wersquoll put serious Shake-
spearian interpretation aside) o find out we need to take a step
back into the Greek philosophical scene and not rush to
judgmentmdashor rush to endorsement either Protagoras would ap-
prove of this deliberationProtagoras was considered the chief of the Sophists intellec-
tuals who were paid to defend the views of their sponsors Tey
were accomplished orators as well as thinkers Originally the

term sophist meant something like our ldquoprofessorrdquo but later a
Sophist was deemed a hired gun a philosopher for hire and one
having no principles of his own Teir arguments supposedly
were merely the instruments of the will of their bosses One may
argue over the virtues of the Sophists but it is certainly not true
that being paid for philosophizing necessarily disqualifies the
employeersquos arguments On the other hand if we think of a
Sophist as something like a political speech writer or the like

Protagoras was one of a spirited group of fastidious thinkers
who tired or at least grew skeptical of Greek mythology with
its pantheon of gods Yes the stories of the gods were often riv-
eting and worth repeating A recent volume by Luc Ferry is
called Te Wisdom of the Myths How Greek Mythology Can
Change Your Life3 Tere was always a moral to the story Her-
cules the last son of Zeus was a dashing and dramatic character
who started as a mighty mortal and became a god upon deathAlthough a bit impetuous and lacking in sobriety he plays well
as a hero Zeus himself is the apotheosis of power but acts
largely without moral authority Even the might of Zeus does not
support the idea that ldquomight makes rightrdquo since might may make
for divine mischief My point is not to survey or psychoanalyze
the denizens of Greek mythology but to make a general point
Mythologies may inspire and guide to some extent our relation
to the hard facts of family life death and sexuality (and some of
the gods tended to be naughty in this way)

mythology Eastern or Western) is simply that it is mythology it
is neither history nor clearly articulated philosophy In too many
ways the gods despite their thespian reacutesumeacutes and magical
powers were not much more than semi- glorified mortals Tis
was the objection of a growing group of Greeks who were mere
mortalsmdashmortals with meaning metaphysics and morality on
their minds And what might the mind do when free to explore
life and its questions apart from the venerable stories of Greek
fascination It might philosophize and so it didProtagoras and his cohorts quested for explanations of a more
abstract but also compelling sort than the old tales could afford
Tey sought principles to explain facts in a universal and logi-
cally coherent manner o be a little unfair to the mythologies
consider the tooth fairy She adds some magical benevolence to
the loss and placement of a baby tooth for children but the fairy
story adds nothing about the nature of benevolence the signifi-
cance of teeth or the significance of the humans who grow and
lose these teeth whether through development (teething) or
decay (the toothless)
Tus to give one example Tales of Miletus tried to find a
cosmic commonality to all things He divined it as water Yes
water which was more than rain oceans lakes and puddles Itwas everywhere so perhaps it was the root and branch of every-
thing Water or moisture in general lives in the clouds in plants
in animals (aquatic land or amphibious) and in thirsty mortals
It condenses and evaporates but never leaves the planet Con-
sidering the presence and power of water Tales extrapolated
that water was more than one more thing on earth however
necessary for life It was rather the unifying principle for exis-
tence Whatever we think of Tales his thinking is not absurd
and it indicates a thirst for philosophical explanation as opposed
to mythological meanderings At least he was trying

But it is Protagoras who calls for our attention Instead of ar-guing for something at the heart of everything (water for Tales)
a principle found in nature Protagoras moved back from nature
to the self After all skeptics had questioned mere mortalsrsquo
ability to know with any confidence what is out there inde-
pendent of themselves Te jaundiced eye sees things differently
from the nonjaundiced eye Children perceive entities invisible
to adults Adults sometimes hallucinatemdashbut perhaps they areseeing what most miss One woman feels cold in a room of degF
and another feels hot Age alters hearing seeing memory and
may jangle judgments Te upshot is that we cannot find a place
to stand to see the world as it is We are simply ill-equipped to
do so Objective truth what is independent of our perceptions
endlessly and mercilessly eludes us
We will return to skepticism when discussing Descartes and
Pascal but Protagoras was not a skeptic He did not withhold
judgments about facts in themselves because we do not have the
ability to know them While recognizing that the skeptics had
dethroned our intellectual confidence in capturing objective re-
ality his point of departure was this we do know our own view-
points judgments and beliefs Tat is we measure things theydo not measure themselves So I take most of Francis Baconrsquos
paintings to be ugly and thus unattractive I am repulsed Tis is
the end of the story or my story Tis is my measurement You
on the contrary may find delight in Baconrsquos tortured figures and
color schemes Tat is your measurement and the end of your
story
Now reconsider the skeptical point made earlier One person
can deem the room cold and another hot Te skeptic might say
we cannot know then what the room is given the variability in
perception But Protagoras claims that the room is hot for person

A and not hot for person B Tere is no contradiction since we
are considering individual perceptions Tere are two measure-
ments each of which is valid Tus Bacon is barbaric to me and
beautiful to youmdashand that is the level best we can do Or perhaps
I will come to adore Baconrsquos paintings and heap scorn on my
former judgment If so then that is my measurement
Tis is rather attractive at first blush After all there is no
dispute in matters of taste or to be more snobby De gustibus
non est disputandum Te avant-garde saxophone playing ofPeter Broumltzmann can send me into the upper reaches of aes-
thetic delight while sending others scurrying from the room
while covering their ears But Protagoras took this insight far
beyond artistic judgments Notice the reference range (or extent)
of Protagorasrsquos statement ldquoMan is the measure of all thingsrdquomdash
matters of taste as well as matters of fact matters of principle
and matters of matter Nothing is excluded
Let us follow this out As we think it through the old Greek
will sound much like modern man If Protagoras is right then
there is no disputing matters of morality either Man is the
measure of what is right and what is wrong what is virtuous and
what is vicious what should be loved and what should be hatedmdash
just as Hamlet claimed oday this thinking is usually put in thelanguage of choice instead of measurement but the idea is the
same If you chose to do X that choice is the end of the matter
Or to suit Protagoras if you measure X as worth doing then it
is worth doing Tis is true whether X refers to sailing stealing
or stampeding cattle in the direction of a Cub Scout outing
But we might say ldquoWho is to judgerdquo Who of us can stand
above him- or herself and others and become objective Yes we
recoil from some ideasmdashsuch as torturing the innocent merely
for pleasure or female genital mutilation But what does that tell
us about reality if there really is such a thing as reality Te claim

that ldquoman is the measure of all thingsrdquo is an all-encompassing
judgment itself Te answer to ldquoWho is to judgerdquo is that we are

philosophy of one of the most infamous serial killers in American
historymdashthe philosophy that allowed and even impelled hisegregious crimes Next I ask them to reconsider their judg-

on this basis But a statement cannot be true unless it accords
with the way the world in fact is and the way we in fact are Pro-
tagoras does capture some truths about perspective For ex-
ample my tastes in food determine how I measure the goodness
of the food I am the measure of that at least It matters nothing
whether a connoisseur thinks me an ignoramus I can only
measure it by what I experience at the moment In that way I am
the measure but am I the expert Am I the knowerTere is a strange implication for Protagorasrsquos view In the
Teaetetus Protagoras even states that error is impossible5 Al-
though he was a teacher he cannot by his own lights teach
anyone o this Socrates inquires
If whatever the individual judges by means of perception is
true for him if no man can assess anotherrsquos experiencebetter than he or can claim authority to examine another
manrsquos judgment and see if it be right or wrong if as we
have repeatedly said only the individual himself can judge
of his own world and what he judges is always true and
correct how could it ever be my friend that Protagoras
was a wise man so wise as to think himself fit to be the
teacher of other men and worth large fees while we in
comparison with him the ignorant ones needed to go and
sit at his feetmdashwe who are ourselves each the measure of
his own wisdom6

be written in Chinese or in English Since each language uses
different symbols for writing its graphic inscription for cat will
differ Tis is true for voicing the word cat as well Trough a
long messy process not instigated by any central planning each
culture selects its own conventions of communication Are not
these two systems of writing measuring reality in very different
ways In point of fact they are not
Both kinds of writing systems (as well as other means ofcommunication) make claims about a reality that are outside
of the systems themselves and outside of the individuals who
use the pictographic or ideographic methods We tacitly saw
this earlier But in both cases a cat is invoked there is a single
referent Te differences in linguistic custom are not differ-
ences in content A cat is a cat in whatever language and it will
not bark however it may be measured Moreover while it may
be vexing in places one can translate a book from English to
Chinese Not everything is lost in translation in fact more is
found than is lost ranslators need have no fear of losing their
livelihood
Staying on matters of taste for a moment (and not morality

reading when you were quite young Tey are likely not the
same as when you became an adult You may still enjoy and
laugh at nursery rhymes but your tastes have expanded Yes
you still love Winnie the Pooh (and I mean the original Pooh
not the Walt Disney version) but you understand and appre-
ciate it more deeply now If so (and substitute your own ex-
amples here if needed) your tastes have at least changed and
have likely improved with age Your earlier judgments were

likely age appropriate but they were limited and (not unex-
pectedly) childish Te apostle Paul notes this in a well-known
turn of phrase ldquoWhen I was a child I talked like a child I
thought like a child I reasoned like a child When I became a
man I put the ways of childhood behind merdquo ( Corinthians

Furthermore the very notion of improvement or progress
(not merely some change in quality) requires and assumes an
objective standard by which to measure improvement (or de-cline) If a baseball batter hits in and in he
has improved based on the best possible average of Tere
is a measurement and it is not the perception of the batter that
determines this measurement Tis is the case in the arts as well
Few knowledgeable about jazz would dispute that John Col-
tranersquos saxophone work improved during his tenure with pianist
Telonious Monkrsquos quartet or that it developed further in Col-
trane own ldquoclassic quartetrdquo (ndash)7 Here the assessment is
not quantitative or statistical but qualitative One might object
that this is a purely subjective judgment (such as whether one
feels hot or not) which is relative to the person hearing Who is
to judge Te answer is straightforward the one whose expe-
rience knowledge and wisdom merit approval Although manydrink wine there are few expert wine tasters A student of mine
is so adept at this art that he can tell what part of the country a
wine came from Not having developed this advanced degree of
skill this is foreign to me However I had no inclination to say
that my judgment on wine is as accurate as Markrsquos Along these
lines I was once embarrassed when one of my students told me
that the wine I was enjoying was ldquothe Kenny G of winesrdquo Tis as
jazz aficionados know was not a compliment about the wine or
about my taste for wine
Artistic judgments involve much more than my quick treatment

But Herodotus may yet rescue Protagoras In his History the
ancient historian notes that Darius a king of ancient Persia (who
was a kind of premodern anthropologist because of his study of
cultural differences) called together some Greeks and askedthem what it would take to cannibalize their dead fathers Te
Greeks needed no time to ponder the proposition since nothing
would move them to such odious paternal desecration Teir
practice was cremation this alone would honor their dead Ten
Darius summoned several Callatians (from India) to join the
Greeks and asked them what would make them cremate their
deceased fathers Te Callatians were as horrified as the Greeks
had been and told Darius to not discuss such atrocities
Had Protagoras heard this he would likely applaud having
found more evidence for his outlook But not all applause is
earned While the Greeks and Callatians observed fundamen-
tally different funeral rites both cultures honored the dead Tat
is only particular practicesmdashnot just any old or new thingmdashwere esteemed right and good in the treatment of corpses and
these practices were not norms for the treatment of the living
In other words death was set apart as uniquely meaningful and
thus required that the living treat the dead with ritual respect
Tus Greeks and Callatians agreed on a deep principle of hon-
oring the dead Tey disagreed on the rule that stems from that
principle In no sense then does the example of cultural rela-
tivity disprove moral agreement across cultures since there was
deep agreement between the cultures C S Lewis makes just
this point in Mere Christianity

Protagoras
I know that some people say the idea of a Law of Nature or
decent behaviour known to all men is unsound because
different civilisations and different ages have had quite dif-
ferent moralities
But this is not true Tere have been differences between
their moralities but these have never amounted to any-
thing like a total difference If anyone will take the trouble
to compare the moral teaching of say the ancient Egyp-
tians Babylonians Hindus Chinese Greeks and Romanswhat will really strike him will be how very like they are to
each other and to our own9
Te case against Protagoras comes down to this If we want to
learn anything if we want to improve as human beings if we
want to condemn the ed Bundys of the world if we want any
kind of educated taste if we desire to understand and honorhumanity then we must reject the ldquoman is the measurerdquo theory
Each person is indeed the measurer of some things Some of
them the individual gets right some of them the individual gets
wrong And in this difference lies all the difference in the world
and even outside of it

I propose that the requirements for being a philosopher (whether
good or bad major or minor professional or layperson) are a
strong and lived-out inclination to pursue truth through the rig-
orous use of human reasoning and to do so with some intel-
lectual facility But sadly even some philosophers disavow the
search for truth In Whatrsquos the Use of ruth French philosopher
Pascal Engel writes ldquoTere is no obligation to say or to be-
lieve that which is truerdquo3 If so why should we read his writings
or those of any other philosopherIs then everyone a philosopher Everyone muses a bit on
where we came from who we are and where we are going But
not all do this very well So while Johnny Rotten (b ) of the
Sex Pistols addressed some philosophical themes in his punk
rock compositions and performances one is reluctant to give
him the title of philosopher Tis is because it is a kind of merit
badge reserved for the few I was recently asked by a precocious
ten-year-old named Liam if I was a philosopher I said I was

about argumentsrdquo We then discussed the nature of an argument
With a little coaxing he told me what an argument was giving
reasons for what you believe often in conversations with those
who believe otherwise I have recruited him for graduate studyin my program

sentences all of which are short but none of which are trivial
Some are more renowned than others A few of them are famous
Tese statements are not impenetrable deceiving the unwary
inquirer with obscurity masquerading as profundity Sadly not

nature of truth how we gain knowledge the meaning of humanexistence death the source of morality and more In my many

Protagoras is not a household name Google him and find out(Te first entry is not surprisingly Wikipedia) Nor do you find
many academic titles analyzing his ideas although he is often
grouped with the Sophists Tis is considered a disreputable
crowd by some wags and is even a byword ldquoYou sophistrdquo Te
charge is that Sophists cared nothing for truth but cared every-
thing about being paid to philosophize for a vested interest
More on these philosophers-for-hire later Even so this oldGreek crystallizes the thought of not a few philosophers and
nonphilosophers Our chosen sentence sums it up
Man is the measure of all things of the things which are
that they are and of things which are not that they are not6
Protagoras gives wings to an idea that many ponder try our
hardest (or not try at all) we cannot break free of ourselvesmdashour
senses our viewpoints our values even our ldquostuffrdquo Te world is
our judgment and nothing more It does not await our judgment
it is our judgment Tere is no objective truth but only various
views from various places at various times by various people
Tings are not our measure but we are the measure of them
Hence Protagoras is the spokesman for relativism sometimescalled nonrealism or perspectivism It is not just that we have no
(or limited) access to objective reality Tat is skepticism Reality
is pretty much exhausted by our perceptions and thoughts Te
real world is our world Myriads have measured Protagoras
wrong at least on this but no one in pursuit of knowledge and
wisdom can ignore him His ghost haunts us still Is there a phil-

students to live this waymdashfor their sakes and mine (It makes for
better papers too) Tus said Socrates the gadfly (or pain-in-
the-neck) of ancient Athens Like Protagoras we know of
Socrates through those who knew his work but unlike Pro-
tagoras we have more substantial sources particularly Plato
And Socrates is a household name Not incidentally the man
who was not an author ended up being the inspiration for the
prolific Plato who was the worldrsquos first systematic philosopher
As philosopher Alfred North Whitehead discerned ldquoTe safestgeneral characterization of the European philosophical tradition
is that it consists of a series of footnotes to Platordquo7 Te footnotes
may praise (Augustine) or blame (Aristotle) but footnotes are
everywhere as well as entire volumes
aking up Socratesrsquos philosophical challenge means exam-
ining just what his famous sentence means in itself and what it
means for us What might an examined life be given the distrac-
tions and overstimulation of postmodern times For Socrates
there is a way to calm the mind and search things out But is
there a place for Socratic dialogue today outside the Socratic
method of many law schools Further old Plato Socratesrsquos
chronicler and student may offer us wisdom pertaining to the
nagging questions of philosophy as he spurns the work of the philodoxers (lovers of opinion) and promotes the call of the phi-
losophers (lovers of wisdom) Worse yet were the misologists (one
of the Platonic corpusrsquos most winning words) those who took an
active role in hating the use of reason itself We may find some
today even in educated enclaves or even on the bestsellers lists
But one can also find Aristotle in popular bookstores always
in the philosophy section (along with less prestigious volumes
such as Led Zeppelin and Philosophy which we must pass over
without further comment) When Aristotle wrote ldquoAll men by
nature desire to knowrdquo he did not mean just the scholars or

teachers but ldquomanrdquomdashthe human race in all its circumstances and
variations Tat means every person whatever social standing
vocation or intelligence Although Aristotle was no egalitarian
(he thought that women were inferior to men and that some were
born to be slaves) he nevertheless appeals to a universal human
condition the desire to get reality right in the time that we have
Augustine the first great Christian philosopher like Socrates
before him strikes a personal note concerning getting reality
right Having examined himself and the leading philosophies ofhis day (including Plato and his footnotes) he confesses with a
cry of the heart addressed to God ldquoYou have made us for
yourself and restless is our heart until it comes to rest in yourdquo
Tis cry is not commonplace as in ldquoMy spirituality gives me
meaningrdquo It is instead the beginning of an argument told in his
autobiography In fact it may be the first autobiography on
record It is no doubt the first philosophical autobiography (if
we exclude the book of Ecclesiastes) Te irascible Jean-Jacques
Rousseau is well known for his autobiography as well but a short
book can only do so much8
Skipping madly over much philosophical history (without any
irreverence or glibness) we arrive at Reneacute Descartes the much
maligned but seldom understood ldquofather of modern philosophyrdquoDescartes was troubled by opinions without backingmdashthose
ideas about ultimate matters untethered from certainty Skep-
ticism was his foe as it is in one way or another for any philos-
opher Tis is because the question arises How do you know
what you claim to know Mere social position or historical tra-
dition will not cinch the deal for this philosopher and scientist
In our language (which itself needs interrogation) the man

edgeable answer it should not be the default response according

with himself Like Augustine but in briefer scope he put this in
autobiographical form in Discourse on Method and to some
extent in Meditations on First Philosophy But Descartesrsquos quest
did not end with himself unlike so much contemporary self-
help literature He is famous for the sentence ldquoI think therefore
I amrdquo But God himself has something to do with that sentence
For Descartes there was no leap of faith in it either Reason was
the guide But how far can reason take us
A contemporary of Descartes had an idea ldquoTe heart has itsreasons that reason knows nothing ofrdquo wrote Blaise Pascal who
was the best phrasemaker of the lot of our philosophers Tis
statement is a window into a worldview Humans have the ca-
pacity to calculate and reason methodically but they may also
know some things by tracing out the contours and resources of
ldquothe heartrdquomdashanother organ of knowledge Philosophers study
many thinkers but few come to love few of them (My graduate
seminar on Kantrsquos Critique of Pure Reason was well worth it but
was no love affair) Pascal on the contrary is much loved by many
He is so loved that people even love things he never actually said
such as ldquoTere is a God-shaped vacuum that only God can fillrdquo
But this paraphrase is not far off the mark though it should be
placed within a larger perspective of Pascalrsquos philosophyTe French polymathrsquos philosophy is far more fascinating than
the CliffsNotes version allows Pascal did not put faith in place
of reason and he was not a one-trick philosopher (Pascalrsquos
wager) Slander and libel have fouled the air about him ob-
scuring his sophisticated treatment of the cost-benefit sense of
believing in religion or not Yet he was neither knave nor poser
Te founder of probability theory and the inventor of the first
working calculating machine had reasons for faith Like Des-
cartes he was bugged by skepticism and like Descartes he ap-
pealed to human nature as a place to start the discussion

Our last sentence is not as well known as the previous ones
but it opens a door of inquiry for us
Te greatest hazard of all losing onersquos self can occur very
quietly in the world as if it were nothing at all
It was penned by an idiosyncratic and famously melancholy
Dane named Soslashren Kierkegaard a philosopher intensely inter-
ested in the self in relation to ultimate reality Tis should sound
familiar since all philosophers have expressed this interest inone way or another But Kierkegaardrsquos way was in a sense as
much psychological as philosophical He intrepidly limned the
inner workings of the self of consciousness in philosophical
categories Like Pascal Kierkegaard wanted to strip away
through existential analysis the layers and dynamics of the self
that keep reality at bay Unlike Pascal and the other philosophers
he was more interested in the analysis of the self than presentingit with arguments for an abstract objective reality Tis may
sound a bit unphilosophical but it is not But that takes time to
tease out properly as I hope you will see
Our seven sentences may be viewed as several doors into
worlds previously unknown Or they may be our irritants to
prod us to move away from facile factoidsmdashldquoDo your own thingrdquoldquoFollow your blissrdquo ldquoKeep Calm and Carry Onrdquomdashto more so-
bering reflections9 Perhaps the sentences are bridges to other
lands of thought Tese philosophical sentences do not sum the
thought of any of the philosophers for these thinkers are far too
deep for that Nor do the seven sentences aim to summarize the
history of philosophy Tat would be a pompous and laughable
claim Some things cannot be put into a nutshell including thenutshell itself But I claim that philosophical activity can be
sparked by just seven sterling sentencesmdashand who knows where
it might lead

Man is the measure of all things
P
Greeks could do philosophy Te basic questions of exis-
tence have never been far from the human mind but the
ancient Greeks excelled at this and their musingsmdashsome frag-
mentary or secondhandmdashhave been preserved in written texts
However much philosophy occurred in exclusively oral cultures
the Greeks valued writing in addition to oral memory and tra-
dition Socrates you remember wrote nothing but generated a vast literature though his dialogues A lesser-known figure who
came after him did write a few things and his famous adage is
worth considering
Protagoras (fifth century BC) is not to be confused with
like-sounding ancient Greek thinkers named Pythagoras or
Parmenides who along with others were pre-Socratic thinkers
(Tis shows the significance of Socrates since philosophy isdated with respect to his life) Tese thinkers are worth inter-
rogating as well and I studied them with profit in a year-long
course in ancient philosophy forty years ago Protagoras

stands out to us though because of his adage about absolute
assessment
Man is the measure of all things of the things which are
that they are and of things which are not that they are not1
His claim is not simply that people measure thingsmdashsuch as
character chariots boats and fishmdashbut that each human is the
measure Each person is the assessment or judgment What
could this mean No person is a slide ruler or scale or Geigercounter although we avail ourselves of such things
W I M
We tend to think that people use a standard of measurement
outside of themselves Even inadequate and one-dimensional
measures such as onersquos IQ score are not determined by how we
feel about themmdashand Mensa is very picky about thisOn the other hand Protagoras has Shakespearersquos Hamlet on
his side at least concerning morality ldquoFor there is nothing either
good or bad but thinking makes it sordquo2 Tat is morals do not
have objective standing rather they are judged differently by
different people Tis quote is from a discussion about Denmark
which Hamlet unlike his interlocutor Rosencrantz said was ldquoaprisonrdquo If Hamlet is right then both Hamlet and Rosencrantz
are right about Denmark
What then was Protagorasrsquos point (Wersquoll put serious Shake-
spearian interpretation aside) o find out we need to take a step
back into the Greek philosophical scene and not rush to
judgmentmdashor rush to endorsement either Protagoras would ap-
prove of this deliberationProtagoras was considered the chief of the Sophists intellec-
tuals who were paid to defend the views of their sponsors Tey
were accomplished orators as well as thinkers Originally the

term sophist meant something like our ldquoprofessorrdquo but later a
Sophist was deemed a hired gun a philosopher for hire and one
having no principles of his own Teir arguments supposedly
were merely the instruments of the will of their bosses One may
argue over the virtues of the Sophists but it is certainly not true
that being paid for philosophizing necessarily disqualifies the
employeersquos arguments On the other hand if we think of a
Sophist as something like a political speech writer or the like
our judgment will change Whatever the intellectual rectitudeof Protagoras he was a perpetual lecturer who articulated and
debated ideas in the marketplace a marketplace of ideas that yet

Protagoras was one of a spirited group of fastidious thinkers
who tired or at least grew skeptical of Greek mythology with
its pantheon of gods Yes the stories of the gods were often riv-
eting and worth repeating A recent volume by Luc Ferry is
called Te Wisdom of the Myths How Greek Mythology Can
Change Your Life3 Tere was always a moral to the story Her-
cules the last son of Zeus was a dashing and dramatic character
who started as a mighty mortal and became a god upon deathAlthough a bit impetuous and lacking in sobriety he plays well
as a hero Zeus himself is the apotheosis of power but acts
largely without moral authority Even the might of Zeus does not
support the idea that ldquomight makes rightrdquo since might may make
for divine mischief My point is not to survey or psychoanalyze
the denizens of Greek mythology but to make a general point
Mythologies may inspire and guide to some extent our relation
to the hard facts of family life death and sexuality (and some of
the gods tended to be naughty in this way)

mythology Eastern or Western) is simply that it is mythology it
is neither history nor clearly articulated philosophy In too many
ways the gods despite their thespian reacutesumeacutes and magical
powers were not much more than semi- glorified mortals Tis
was the objection of a growing group of Greeks who were mere
mortalsmdashmortals with meaning metaphysics and morality on
their minds And what might the mind do when free to explore
life and its questions apart from the venerable stories of Greek
fascination It might philosophize and so it didProtagoras and his cohorts quested for explanations of a more
abstract but also compelling sort than the old tales could afford
Tey sought principles to explain facts in a universal and logi-
cally coherent manner o be a little unfair to the mythologies
consider the tooth fairy She adds some magical benevolence to
the loss and placement of a baby tooth for children but the fairy
story adds nothing about the nature of benevolence the signifi-
cance of teeth or the significance of the humans who grow and
lose these teeth whether through development (teething) or
decay (the toothless)
Tus to give one example Tales of Miletus tried to find a
cosmic commonality to all things He divined it as water Yes
water which was more than rain oceans lakes and puddles Itwas everywhere so perhaps it was the root and branch of every-
thing Water or moisture in general lives in the clouds in plants
in animals (aquatic land or amphibious) and in thirsty mortals
It condenses and evaporates but never leaves the planet Con-
sidering the presence and power of water Tales extrapolated
that water was more than one more thing on earth however
necessary for life It was rather the unifying principle for exis-
tence Whatever we think of Tales his thinking is not absurd
and it indicates a thirst for philosophical explanation as opposed
to mythological meanderings At least he was trying

Protagoras
D W D R
But it is Protagoras who calls for our attention Instead of ar-guing for something at the heart of everything (water for Tales)
a principle found in nature Protagoras moved back from nature
to the self After all skeptics had questioned mere mortalsrsquo
ability to know with any confidence what is out there inde-
pendent of themselves Te jaundiced eye sees things differently
from the nonjaundiced eye Children perceive entities invisible
to adults Adults sometimes hallucinatemdashbut perhaps they areseeing what most miss One woman feels cold in a room of degF
and another feels hot Age alters hearing seeing memory and
may jangle judgments Te upshot is that we cannot find a place
to stand to see the world as it is We are simply ill-equipped to
do so Objective truth what is independent of our perceptions
endlessly and mercilessly eludes us
We will return to skepticism when discussing Descartes and
Pascal but Protagoras was not a skeptic He did not withhold
judgments about facts in themselves because we do not have the
ability to know them While recognizing that the skeptics had
dethroned our intellectual confidence in capturing objective re-
ality his point of departure was this we do know our own view-
points judgments and beliefs Tat is we measure things theydo not measure themselves So I take most of Francis Baconrsquos
paintings to be ugly and thus unattractive I am repulsed Tis is
the end of the story or my story Tis is my measurement You
on the contrary may find delight in Baconrsquos tortured figures and
color schemes Tat is your measurement and the end of your
story
Now reconsider the skeptical point made earlier One person
can deem the room cold and another hot Te skeptic might say
we cannot know then what the room is given the variability in
perception But Protagoras claims that the room is hot for person

A and not hot for person B Tere is no contradiction since we
are considering individual perceptions Tere are two measure-
ments each of which is valid Tus Bacon is barbaric to me and
beautiful to youmdashand that is the level best we can do Or perhaps
I will come to adore Baconrsquos paintings and heap scorn on my
former judgment If so then that is my measurement
Tis is rather attractive at first blush After all there is no
dispute in matters of taste or to be more snobby De gustibus
non est disputandum Te avant-garde saxophone playing ofPeter Broumltzmann can send me into the upper reaches of aes-
thetic delight while sending others scurrying from the room
while covering their ears But Protagoras took this insight far
beyond artistic judgments Notice the reference range (or extent)
of Protagorasrsquos statement ldquoMan is the measure of all thingsrdquomdash
matters of taste as well as matters of fact matters of principle
and matters of matter Nothing is excluded
Let us follow this out As we think it through the old Greek
will sound much like modern man If Protagoras is right then
there is no disputing matters of morality either Man is the
measure of what is right and what is wrong what is virtuous and
what is vicious what should be loved and what should be hatedmdash
just as Hamlet claimed oday this thinking is usually put in thelanguage of choice instead of measurement but the idea is the
same If you chose to do X that choice is the end of the matter
Or to suit Protagoras if you measure X as worth doing then it
is worth doing Tis is true whether X refers to sailing stealing
or stampeding cattle in the direction of a Cub Scout outing
But we might say ldquoWho is to judgerdquo Who of us can stand
above him- or herself and others and become objective Yes we
recoil from some ideasmdashsuch as torturing the innocent merely
for pleasure or female genital mutilation But what does that tell
us about reality if there really is such a thing as reality Te claim

that ldquoman is the measure of all thingsrdquo is an all-encompassing
judgment itself Te answer to ldquoWho is to judgerdquo is that we are
the measure of all things Tat is there is nothing outside of
human judgment by which it might be judged But why would
Protagoras (or anyone else) consider that to be reality itself

Besides being a serial killer ed Bundy was a philosophical
thinker of the Protagorean type Remarkably his philosophy wascaught on tape before he raped and killed a young woman She
was one of dozens of his prey As reported in Louis Pojmanrsquos text
Moral Philosophy Bundy said
I learned that all moral judgments are ldquovalue judgmentsrdquo
that all value judgments are subjective and that none can
be proved to be either ldquorightrdquo or ldquowrongrdquo I even read some-where that the Chief Justice of the United States had written
that the American Constitution expressed nothing more
than collective value judgments Believe it or not I figured
out for myselfmdashwhat apparently the Chief Justice couldnrsquot
figure out for himselfmdashthat if the rationality of one value
judgment was zero multiplying it by millions would not
make it one whit more rational Nor is there any ldquoreasonrdquo
to obey the law for anyone like myself who has the
boldness and daring ldquothe strength of characterrdquo to throw
off its shackles
I discovered that to become truly free truly unfettered
I had to become truly uninhibited And I quickly discovered
that the greatest obstacle to my freedom the greatest blockand limitation to it consists in the insupportable ldquovalue

Why should I be willing to sacrifice my pleasure more for

When teaching ethics to undergraduates at a secular school I
often hand out this Bundy quotation but without identifying the
speaker I then ask them to write a paragraph on whether they
agree with its basic idea Most students approve of the unknown
authorrsquos sentiments I then reveal that this statement was the
philosophy of one of the most infamous serial killers in American
historymdashthe philosophy that allowed and even impelled hisegregious crimes Next I ask them to reconsider their judg-
ments Te results are usually mixed but the majority of stu-
dents show dismay and surprise that they were in agreement
with a view that justified serial rape and murder
Yet today a television seriesmdasha comedy nonethelessmdashis about
a serial killer named Dexter o top that off there is even a book
called Dexter and Philosophy Mind over Spatter Can such atroc-
ities be lifted so easily from bloody reality and into a neutral
realm of entertainment For many it can and so they seem to
agree with Protagoras at least implicitly there is no objective

us and nothing beneath us It is all merely neutral and we make
the callmdashon everything ldquoMan is the measure of all thingsrdquoSo then what does this sentence tell us about philosophy and

existentially Tey often capture some truth and so seduce us
on this basis But a statement cannot be true unless it accords
with the way the world in fact is and the way we in fact are Pro-
tagoras does capture some truths about perspective For ex-
ample my tastes in food determine how I measure the goodness
of the food I am the measure of that at least It matters nothing
whether a connoisseur thinks me an ignoramus I can only
measure it by what I experience at the moment In that way I am
the measure but am I the expert Am I the knowerTere is a strange implication for Protagorasrsquos view In the
Teaetetus Protagoras even states that error is impossible5 Al-
though he was a teacher he cannot by his own lights teach
anyone o this Socrates inquires
If whatever the individual judges by means of perception is
true for him if no man can assess anotherrsquos experiencebetter than he or can claim authority to examine another
manrsquos judgment and see if it be right or wrong if as we
have repeatedly said only the individual himself can judge
of his own world and what he judges is always true and
correct how could it ever be my friend that Protagoras
was a wise man so wise as to think himself fit to be the
teacher of other men and worth large fees while we in
comparison with him the ignorant ones needed to go and
sit at his feetmdashwe who are ourselves each the measure of
his own wisdom6

human languages For example the general concept of cat may
be written in Chinese or in English Since each language uses
different symbols for writing its graphic inscription for cat will
differ Tis is true for voicing the word cat as well Trough a
long messy process not instigated by any central planning each
culture selects its own conventions of communication Are not
these two systems of writing measuring reality in very different
ways In point of fact they are not
Both kinds of writing systems (as well as other means ofcommunication) make claims about a reality that are outside
of the systems themselves and outside of the individuals who
use the pictographic or ideographic methods We tacitly saw
this earlier But in both cases a cat is invoked there is a single
referent Te differences in linguistic custom are not differ-
ences in content A cat is a cat in whatever language and it will
not bark however it may be measured Moreover while it may
be vexing in places one can translate a book from English to
Chinese Not everything is lost in translation in fact more is
found than is lost ranslators need have no fear of losing their
livelihood
Staying on matters of taste for a moment (and not morality
for now) are all people equally skilled in measurement Tepoet and literary critic S Eliot advocated the cultivation of
ldquoeducated tasterdquo Consider your preferences in music and
reading when you were quite young Tey are likely not the
same as when you became an adult You may still enjoy and
laugh at nursery rhymes but your tastes have expanded Yes
you still love Winnie the Pooh (and I mean the original Pooh
not the Walt Disney version) but you understand and appre-
ciate it more deeply now If so (and substitute your own ex-
amples here if needed) your tastes have at least changed and
have likely improved with age Your earlier judgments were

likely age appropriate but they were limited and (not unex-
pectedly) childish Te apostle Paul notes this in a well-known
turn of phrase ldquoWhen I was a child I talked like a child I
thought like a child I reasoned like a child When I became a
man I put the ways of childhood behind merdquo ( Corinthians
see also Hebrews -)
Furthermore the very notion of improvement or progress
(not merely some change in quality) requires and assumes an
objective standard by which to measure improvement (or de-cline) If a baseball batter hits in and in he
has improved based on the best possible average of Tere
is a measurement and it is not the perception of the batter that
determines this measurement Tis is the case in the arts as well
Few knowledgeable about jazz would dispute that John Col-
tranersquos saxophone work improved during his tenure with pianist
Telonious Monkrsquos quartet or that it developed further in Col-
trane own ldquoclassic quartetrdquo (ndash)7 Here the assessment is
not quantitative or statistical but qualitative One might object
that this is a purely subjective judgment (such as whether one
feels hot or not) which is relative to the person hearing Who is
to judge Te answer is straightforward the one whose expe-
rience knowledge and wisdom merit approval Although manydrink wine there are few expert wine tasters A student of mine
is so adept at this art that he can tell what part of the country a
wine came from Not having developed this advanced degree of
skill this is foreign to me However I had no inclination to say
that my judgment on wine is as accurate as Markrsquos Along these
lines I was once embarrassed when one of my students told me
that the wine I was enjoying was ldquothe Kenny G of winesrdquo Tis as
jazz aficionados know was not a compliment about the wine or
about my taste for wine
Artistic judgments involve much more than my quick treatment

beauty is not only in the eye of the beholder If not we are haunted

But Herodotus may yet rescue Protagoras In his History the
ancient historian notes that Darius a king of ancient Persia (who
was a kind of premodern anthropologist because of his study of
cultural differences) called together some Greeks and askedthem what it would take to cannibalize their dead fathers Te
Greeks needed no time to ponder the proposition since nothing
would move them to such odious paternal desecration Teir
practice was cremation this alone would honor their dead Ten
Darius summoned several Callatians (from India) to join the
Greeks and asked them what would make them cremate their
deceased fathers Te Callatians were as horrified as the Greeks
had been and told Darius to not discuss such atrocities
Had Protagoras heard this he would likely applaud having
found more evidence for his outlook But not all applause is
earned While the Greeks and Callatians observed fundamen-
tally different funeral rites both cultures honored the dead Tat
is only particular practicesmdashnot just any old or new thingmdashwere esteemed right and good in the treatment of corpses and
these practices were not norms for the treatment of the living
In other words death was set apart as uniquely meaningful and
thus required that the living treat the dead with ritual respect
Tus Greeks and Callatians agreed on a deep principle of hon-
oring the dead Tey disagreed on the rule that stems from that
principle In no sense then does the example of cultural rela-
tivity disprove moral agreement across cultures since there was
deep agreement between the cultures C S Lewis makes just
this point in Mere Christianity

Protagoras
I know that some people say the idea of a Law of Nature or
decent behaviour known to all men is unsound because
different civilisations and different ages have had quite dif-
ferent moralities
But this is not true Tere have been differences between
their moralities but these have never amounted to any-
thing like a total difference If anyone will take the trouble
to compare the moral teaching of say the ancient Egyp-
tians Babylonians Hindus Chinese Greeks and Romanswhat will really strike him will be how very like they are to
each other and to our own9
Te case against Protagoras comes down to this If we want to
learn anything if we want to improve as human beings if we
want to condemn the ed Bundys of the world if we want any
kind of educated taste if we desire to understand and honorhumanity then we must reject the ldquoman is the measurerdquo theory
Each person is indeed the measurer of some things Some of
them the individual gets right some of them the individual gets
wrong And in this difference lies all the difference in the world
and even outside of it

Protagoras is not a household name Google him and find out(Te first entry is not surprisingly Wikipedia) Nor do you find
many academic titles analyzing his ideas although he is often
grouped with the Sophists Tis is considered a disreputable
crowd by some wags and is even a byword ldquoYou sophistrdquo Te
charge is that Sophists cared nothing for truth but cared every-
thing about being paid to philosophize for a vested interest
More on these philosophers-for-hire later Even so this oldGreek crystallizes the thought of not a few philosophers and
nonphilosophers Our chosen sentence sums it up
Man is the measure of all things of the things which are
that they are and of things which are not that they are not6
Protagoras gives wings to an idea that many ponder try our
hardest (or not try at all) we cannot break free of ourselvesmdashour
senses our viewpoints our values even our ldquostuffrdquo Te world is
our judgment and nothing more It does not await our judgment
it is our judgment Tere is no objective truth but only various
views from various places at various times by various people
Tings are not our measure but we are the measure of them
Hence Protagoras is the spokesman for relativism sometimescalled nonrealism or perspectivism It is not just that we have no
(or limited) access to objective reality Tat is skepticism Reality
is pretty much exhausted by our perceptions and thoughts Te
real world is our world Myriads have measured Protagoras

students to live this waymdashfor their sakes and mine (It makes for
better papers too) Tus said Socrates the gadfly (or pain-in-
the-neck) of ancient Athens Like Protagoras we know of
Socrates through those who knew his work but unlike Pro-
tagoras we have more substantial sources particularly Plato
And Socrates is a household name Not incidentally the man
who was not an author ended up being the inspiration for the
prolific Plato who was the worldrsquos first systematic philosopher
As philosopher Alfred North Whitehead discerned ldquoTe safestgeneral characterization of the European philosophical tradition
is that it consists of a series of footnotes to Platordquo7 Te footnotes
may praise (Augustine) or blame (Aristotle) but footnotes are
everywhere as well as entire volumes
aking up Socratesrsquos philosophical challenge means exam-
ining just what his famous sentence means in itself and what it
means for us What might an examined life be given the distrac-
tions and overstimulation of postmodern times For Socrates
there is a way to calm the mind and search things out But is
there a place for Socratic dialogue today outside the Socratic
method of many law schools Further old Plato Socratesrsquos
chronicler and student may offer us wisdom pertaining to the
nagging questions of philosophy as he spurns the work of the philodoxers (lovers of opinion) and promotes the call of the phi-
losophers (lovers of wisdom) Worse yet were the misologists (one
of the Platonic corpusrsquos most winning words) those who took an
active role in hating the use of reason itself We may find some
today even in educated enclaves or even on the bestsellers lists
But one can also find Aristotle in popular bookstores always
in the philosophy section (along with less prestigious volumes
such as Led Zeppelin and Philosophy which we must pass over
without further comment) When Aristotle wrote ldquoAll men by
nature desire to knowrdquo he did not mean just the scholars or

teachers but ldquomanrdquomdashthe human race in all its circumstances and
variations Tat means every person whatever social standing
vocation or intelligence Although Aristotle was no egalitarian
(he thought that women were inferior to men and that some were
born to be slaves) he nevertheless appeals to a universal human
condition the desire to get reality right in the time that we have
Augustine the first great Christian philosopher like Socrates
before him strikes a personal note concerning getting reality
right Having examined himself and the leading philosophies ofhis day (including Plato and his footnotes) he confesses with a
cry of the heart addressed to God ldquoYou have made us for
yourself and restless is our heart until it comes to rest in yourdquo
Tis cry is not commonplace as in ldquoMy spirituality gives me
meaningrdquo It is instead the beginning of an argument told in his
autobiography In fact it may be the first autobiography on
record It is no doubt the first philosophical autobiography (if
we exclude the book of Ecclesiastes) Te irascible Jean-Jacques
Rousseau is well known for his autobiography as well but a short
book can only do so much8
Skipping madly over much philosophical history (without any
irreverence or glibness) we arrive at Reneacute Descartes the much
maligned but seldom understood ldquofather of modern philosophyrdquoDescartes was troubled by opinions without backingmdashthose
ideas about ultimate matters untethered from certainty Skep-
ticism was his foe as it is in one way or another for any philos-
opher Tis is because the question arises How do you know
what you claim to know Mere social position or historical tra-
dition will not cinch the deal for this philosopher and scientist
In our language (which itself needs interrogation) the man
ldquowanted proofrdquo While ldquoI donrsquot knowrdquo is often the most knowl-
edgeable answer it should not be the default response according
to Descartes Tis apprehension led him on a quest that began

with himself Like Augustine but in briefer scope he put this in
autobiographical form in Discourse on Method and to some
extent in Meditations on First Philosophy But Descartesrsquos quest
did not end with himself unlike so much contemporary self-
help literature He is famous for the sentence ldquoI think therefore
I amrdquo But God himself has something to do with that sentence
For Descartes there was no leap of faith in it either Reason was
the guide But how far can reason take us
A contemporary of Descartes had an idea ldquoTe heart has itsreasons that reason knows nothing ofrdquo wrote Blaise Pascal who
was the best phrasemaker of the lot of our philosophers Tis
statement is a window into a worldview Humans have the ca-
pacity to calculate and reason methodically but they may also
know some things by tracing out the contours and resources of
ldquothe heartrdquomdashanother organ of knowledge Philosophers study
many thinkers but few come to love few of them (My graduate
seminar on Kantrsquos Critique of Pure Reason was well worth it but
was no love affair) Pascal on the contrary is much loved by many
He is so loved that people even love things he never actually said
such as ldquoTere is a God-shaped vacuum that only God can fillrdquo
But this paraphrase is not far off the mark though it should be
placed within a larger perspective of Pascalrsquos philosophyTe French polymathrsquos philosophy is far more fascinating than
the CliffsNotes version allows Pascal did not put faith in place
of reason and he was not a one-trick philosopher (Pascalrsquos
wager) Slander and libel have fouled the air about him ob-
scuring his sophisticated treatment of the cost-benefit sense of
believing in religion or not Yet he was neither knave nor poser
Te founder of probability theory and the inventor of the first
working calculating machine had reasons for faith Like Des-
cartes he was bugged by skepticism and like Descartes he ap-
pealed to human nature as a place to start the discussion

Our last sentence is not as well known as the previous ones
but it opens a door of inquiry for us
Te greatest hazard of all losing onersquos self can occur very
quietly in the world as if it were nothing at all
It was penned by an idiosyncratic and famously melancholy
Dane named Soslashren Kierkegaard a philosopher intensely inter-
ested in the self in relation to ultimate reality Tis should sound
familiar since all philosophers have expressed this interest inone way or another But Kierkegaardrsquos way was in a sense as
much psychological as philosophical He intrepidly limned the
inner workings of the self of consciousness in philosophical
categories Like Pascal Kierkegaard wanted to strip away
through existential analysis the layers and dynamics of the self
that keep reality at bay Unlike Pascal and the other philosophers
he was more interested in the analysis of the self than presentingit with arguments for an abstract objective reality Tis may
sound a bit unphilosophical but it is not But that takes time to
tease out properly as I hope you will see
Our seven sentences may be viewed as several doors into
worlds previously unknown Or they may be our irritants to
prod us to move away from facile factoidsmdashldquoDo your own thingrdquoldquoFollow your blissrdquo ldquoKeep Calm and Carry Onrdquomdashto more so-
bering reflections9 Perhaps the sentences are bridges to other
lands of thought Tese philosophical sentences do not sum the
thought of any of the philosophers for these thinkers are far too
deep for that Nor do the seven sentences aim to summarize the
history of philosophy Tat would be a pompous and laughable
claim Some things cannot be put into a nutshell including thenutshell itself But I claim that philosophical activity can be
sparked by just seven sterling sentencesmdashand who knows where
it might lead

PROTAGORAS
Man is the measure of all things
P
Greeks could do philosophy Te basic questions of exis-
tence have never been far from the human mind but the
ancient Greeks excelled at this and their musingsmdashsome frag-
mentary or secondhandmdashhave been preserved in written texts
However much philosophy occurred in exclusively oral cultures
the Greeks valued writing in addition to oral memory and tra-
dition Socrates you remember wrote nothing but generated a vast literature though his dialogues A lesser-known figure who
came after him did write a few things and his famous adage is
worth considering
Protagoras (fifth century BC) is not to be confused with
like-sounding ancient Greek thinkers named Pythagoras or
Parmenides who along with others were pre-Socratic thinkers
(Tis shows the significance of Socrates since philosophy isdated with respect to his life) Tese thinkers are worth inter-
rogating as well and I studied them with profit in a year-long
course in ancient philosophy forty years ago Protagoras

stands out to us though because of his adage about absolute
assessment
Man is the measure of all things of the things which are
that they are and of things which are not that they are not1
His claim is not simply that people measure thingsmdashsuch as
character chariots boats and fishmdashbut that each human is the
measure Each person is the assessment or judgment What
could this mean No person is a slide ruler or scale or Geigercounter although we avail ourselves of such things
W I M
We tend to think that people use a standard of measurement
outside of themselves Even inadequate and one-dimensional
measures such as onersquos IQ score are not determined by how we
feel about themmdashand Mensa is very picky about thisOn the other hand Protagoras has Shakespearersquos Hamlet on
his side at least concerning morality ldquoFor there is nothing either
good or bad but thinking makes it sordquo2 Tat is morals do not
have objective standing rather they are judged differently by
different people Tis quote is from a discussion about Denmark
which Hamlet unlike his interlocutor Rosencrantz said was ldquoaprisonrdquo If Hamlet is right then both Hamlet and Rosencrantz
are right about Denmark
What then was Protagorasrsquos point (Wersquoll put serious Shake-
spearian interpretation aside) o find out we need to take a step
back into the Greek philosophical scene and not rush to
judgmentmdashor rush to endorsement either Protagoras would ap-

Sophist was deemed a hired gun a philosopher for hire and one

were merely the instruments of the will of their bosses One may
argue over the virtues of the Sophists but it is certainly not true

Sophist as something like a political speech writer or the like

Protagoras was one of a spirited group of fastidious thinkers
who tired or at least grew skeptical of Greek mythology with
its pantheon of gods Yes the stories of the gods were often riv-
eting and worth repeating A recent volume by Luc Ferry is
called Te Wisdom of the Myths How Greek Mythology Can
Change Your Life3 Tere was always a moral to the story Her-
cules the last son of Zeus was a dashing and dramatic character
who started as a mighty mortal and became a god upon deathAlthough a bit impetuous and lacking in sobriety he plays well
as a hero Zeus himself is the apotheosis of power but acts
largely without moral authority Even the might of Zeus does not
support the idea that ldquomight makes rightrdquo since might may make
for divine mischief My point is not to survey or psychoanalyze
the denizens of Greek mythology but to make a general point
Mythologies may inspire and guide to some extent our relation
to the hard facts of family life death and sexuality (and some of
the gods tended to be naughty in this way)
Nevertheless the problem with Greek mythology (or any

mythology Eastern or Western) is simply that it is mythology it
is neither history nor clearly articulated philosophy In too many
ways the gods despite their thespian reacutesumeacutes and magical
powers were not much more than semi- glorified mortals Tis
was the objection of a growing group of Greeks who were mere
mortalsmdashmortals with meaning metaphysics and morality on
their minds And what might the mind do when free to explore
life and its questions apart from the venerable stories of Greek
fascination It might philosophize and so it didProtagoras and his cohorts quested for explanations of a more
abstract but also compelling sort than the old tales could afford
Tey sought principles to explain facts in a universal and logi-
cally coherent manner o be a little unfair to the mythologies
consider the tooth fairy She adds some magical benevolence to
the loss and placement of a baby tooth for children but the fairy
story adds nothing about the nature of benevolence the signifi-
cance of teeth or the significance of the humans who grow and
lose these teeth whether through development (teething) or
decay (the toothless)
Tus to give one example Tales of Miletus tried to find a
cosmic commonality to all things He divined it as water Yes
water which was more than rain oceans lakes and puddles Itwas everywhere so perhaps it was the root and branch of every-
thing Water or moisture in general lives in the clouds in plants
in animals (aquatic land or amphibious) and in thirsty mortals
It condenses and evaporates but never leaves the planet Con-
sidering the presence and power of water Tales extrapolated
that water was more than one more thing on earth however
necessary for life It was rather the unifying principle for exis-
tence Whatever we think of Tales his thinking is not absurd
and it indicates a thirst for philosophical explanation as opposed
to mythological meanderings At least he was trying

Protagoras

But it is Protagoras who calls for our attention Instead of ar-guing for something at the heart of everything (water for Tales)
a principle found in nature Protagoras moved back from nature
to the self After all skeptics had questioned mere mortalsrsquo
ability to know with any confidence what is out there inde-
pendent of themselves Te jaundiced eye sees things differently
from the nonjaundiced eye Children perceive entities invisible
to adults Adults sometimes hallucinatemdashbut perhaps they areseeing what most miss One woman feels cold in a room of degF
and another feels hot Age alters hearing seeing memory and
may jangle judgments Te upshot is that we cannot find a place
to stand to see the world as it is We are simply ill-equipped to
do so Objective truth what is independent of our perceptions
endlessly and mercilessly eludes us
We will return to skepticism when discussing Descartes and
Pascal but Protagoras was not a skeptic He did not withhold
judgments about facts in themselves because we do not have the
ability to know them While recognizing that the skeptics had
dethroned our intellectual confidence in capturing objective re-
ality his point of departure was this we do know our own view-
points judgments and beliefs Tat is we measure things theydo not measure themselves So I take most of Francis Baconrsquos
paintings to be ugly and thus unattractive I am repulsed Tis is
the end of the story or my story Tis is my measurement You
on the contrary may find delight in Baconrsquos tortured figures and
color schemes Tat is your measurement and the end of your
story
Now reconsider the skeptical point made earlier One person
can deem the room cold and another hot Te skeptic might say
we cannot know then what the room is given the variability in
perception But Protagoras claims that the room is hot for person

A and not hot for person B Tere is no contradiction since we
are considering individual perceptions Tere are two measure-
ments each of which is valid Tus Bacon is barbaric to me and
beautiful to youmdashand that is the level best we can do Or perhaps
I will come to adore Baconrsquos paintings and heap scorn on my
former judgment If so then that is my measurement
Tis is rather attractive at first blush After all there is no
dispute in matters of taste or to be more snobby De gustibus
non est disputandum Te avant-garde saxophone playing ofPeter Broumltzmann can send me into the upper reaches of aes-
thetic delight while sending others scurrying from the room
while covering their ears But Protagoras took this insight far
beyond artistic judgments Notice the reference range (or extent)
of Protagorasrsquos statement ldquoMan is the measure of all thingsrdquomdash
matters of taste as well as matters of fact matters of principle
and matters of matter Nothing is excluded
Let us follow this out As we think it through the old Greek
will sound much like modern man If Protagoras is right then
there is no disputing matters of morality either Man is the
measure of what is right and what is wrong what is virtuous and
what is vicious what should be loved and what should be hatedmdash
just as Hamlet claimed oday this thinking is usually put in thelanguage of choice instead of measurement but the idea is the
same If you chose to do X that choice is the end of the matter
Or to suit Protagoras if you measure X as worth doing then it
is worth doing Tis is true whether X refers to sailing stealing
or stampeding cattle in the direction of a Cub Scout outing
But we might say ldquoWho is to judgerdquo Who of us can stand
above him- or herself and others and become objective Yes we
recoil from some ideasmdashsuch as torturing the innocent merely
for pleasure or female genital mutilation But what does that tell
us about reality if there really is such a thing as reality Te claim

that ldquoman is the measure of all thingsrdquo is an all-encompassing
judgment itself Te answer to ldquoWho is to judgerdquo is that we are

Besides being a serial killer ed Bundy was a philosophical

Moral Philosophy Bundy said
I learned that all moral judgments are ldquovalue judgmentsrdquo
that all value judgments are subjective and that none can
be proved to be either ldquorightrdquo or ldquowrongrdquo I even read some-where that the Chief Justice of the United States had written
that the American Constitution expressed nothing more
than collective value judgments Believe it or not I figured
out for myselfmdashwhat apparently the Chief Justice couldnrsquot
figure out for himselfmdashthat if the rationality of one value
judgment was zero multiplying it by millions would not
make it one whit more rational Nor is there any ldquoreasonrdquo
to obey the law for anyone like myself who has the
boldness and daring ldquothe strength of characterrdquo to throw
off its shackles
I discovered that to become truly free truly unfettered
I had to become truly uninhibited And I quickly discovered
that the greatest obstacle to my freedom the greatest blockand limitation to it consists in the insupportable ldquovalue

on this basis But a statement cannot be true unless it accords
with the way the world in fact is and the way we in fact are Pro-
tagoras does capture some truths about perspective For ex-
ample my tastes in food determine how I measure the goodness
of the food I am the measure of that at least It matters nothing
whether a connoisseur thinks me an ignoramus I can only
measure it by what I experience at the moment In that way I am
the measure but am I the expert Am I the knowerTere is a strange implication for Protagorasrsquos view In the
Teaetetus Protagoras even states that error is impossible5 Al-
though he was a teacher he cannot by his own lights teach
anyone o this Socrates inquires
If whatever the individual judges by means of perception is
true for him if no man can assess anotherrsquos experiencebetter than he or can claim authority to examine another
manrsquos judgment and see if it be right or wrong if as we
have repeatedly said only the individual himself can judge
of his own world and what he judges is always true and
correct how could it ever be my friend that Protagoras
was a wise man so wise as to think himself fit to be the
teacher of other men and worth large fees while we in
comparison with him the ignorant ones needed to go and
sit at his feetmdashwe who are ourselves each the measure of
his own wisdom6

be written in Chinese or in English Since each language uses
different symbols for writing its graphic inscription for cat will
differ Tis is true for voicing the word cat as well Trough a
long messy process not instigated by any central planning each
culture selects its own conventions of communication Are not
these two systems of writing measuring reality in very different
ways In point of fact they are not
Both kinds of writing systems (as well as other means ofcommunication) make claims about a reality that are outside
of the systems themselves and outside of the individuals who
use the pictographic or ideographic methods We tacitly saw
this earlier But in both cases a cat is invoked there is a single
referent Te differences in linguistic custom are not differ-
ences in content A cat is a cat in whatever language and it will
not bark however it may be measured Moreover while it may
be vexing in places one can translate a book from English to
Chinese Not everything is lost in translation in fact more is
found than is lost ranslators need have no fear of losing their
livelihood

ciate it more deeply now If so (and substitute your own ex-
amples here if needed) your tastes have at least changed and

pectedly) childish Te apostle Paul notes this in a well-known
turn of phrase ldquoWhen I was a child I talked like a child I
thought like a child I reasoned like a child When I became a
man I put the ways of childhood behind merdquo ( Corinthians

Furthermore the very notion of improvement or progress
(not merely some change in quality) requires and assumes an
objective standard by which to measure improvement (or de-cline) If a baseball batter hits in and in he
has improved based on the best possible average of Tere
is a measurement and it is not the perception of the batter that
determines this measurement Tis is the case in the arts as well
Few knowledgeable about jazz would dispute that John Col-
tranersquos saxophone work improved during his tenure with pianist
Telonious Monkrsquos quartet or that it developed further in Col-
trane own ldquoclassic quartetrdquo (ndash)7 Here the assessment is
not quantitative or statistical but qualitative One might object
that this is a purely subjective judgment (such as whether one
feels hot or not) which is relative to the person hearing Who is
to judge Te answer is straightforward the one whose expe-
rience knowledge and wisdom merit approval Although manydrink wine there are few expert wine tasters A student of mine
is so adept at this art that he can tell what part of the country a
wine came from Not having developed this advanced degree of
skill this is foreign to me However I had no inclination to say
that my judgment on wine is as accurate as Markrsquos Along these
lines I was once embarrassed when one of my students told me
that the wine I was enjoying was ldquothe Kenny G of winesrdquo Tis as
jazz aficionados know was not a compliment about the wine or
about my taste for wine

But Herodotus may yet rescue Protagoras In his History the
ancient historian notes that Darius a king of ancient Persia (who
was a kind of premodern anthropologist because of his study of
cultural differences) called together some Greeks and askedthem what it would take to cannibalize their dead fathers Te
Greeks needed no time to ponder the proposition since nothing
would move them to such odious paternal desecration Teir
practice was cremation this alone would honor their dead Ten
Darius summoned several Callatians (from India) to join the
Greeks and asked them what would make them cremate their
deceased fathers Te Callatians were as horrified as the Greeks
had been and told Darius to not discuss such atrocities
Had Protagoras heard this he would likely applaud having
found more evidence for his outlook But not all applause is
earned While the Greeks and Callatians observed fundamen-
tally different funeral rites both cultures honored the dead Tat
is only particular practicesmdashnot just any old or new thingmdashwere esteemed right and good in the treatment of corpses and
these practices were not norms for the treatment of the living
In other words death was set apart as uniquely meaningful and
thus required that the living treat the dead with ritual respect
Tus Greeks and Callatians agreed on a deep principle of hon-
oring the dead Tey disagreed on the rule that stems from that
principle In no sense then does the example of cultural rela-
tivity disprove moral agreement across cultures since there was
deep agreement between the cultures C S Lewis makes just
this point in Mere Christianity

Protagoras
I know that some people say the idea of a Law of Nature or
decent behaviour known to all men is unsound because
different civilisations and different ages have had quite dif-
ferent moralities
But this is not true Tere have been differences between
their moralities but these have never amounted to any-
thing like a total difference If anyone will take the trouble
to compare the moral teaching of say the ancient Egyp-
tians Babylonians Hindus Chinese Greeks and Romanswhat will really strike him will be how very like they are to
each other and to our own9
Te case against Protagoras comes down to this If we want to
learn anything if we want to improve as human beings if we
want to condemn the ed Bundys of the world if we want any
kind of educated taste if we desire to understand and honorhumanity then we must reject the ldquoman is the measurerdquo theory
Each person is indeed the measurer of some things Some of
them the individual gets right some of them the individual gets
wrong And in this difference lies all the difference in the world
and even outside of it

Protagoras is not a household name Google him and find out(Te first entry is not surprisingly Wikipedia) Nor do you find
many academic titles analyzing his ideas although he is often
grouped with the Sophists Tis is considered a disreputable
crowd by some wags and is even a byword ldquoYou sophistrdquo Te
charge is that Sophists cared nothing for truth but cared every-
thing about being paid to philosophize for a vested interest
More on these philosophers-for-hire later Even so this oldGreek crystallizes the thought of not a few philosophers and
nonphilosophers Our chosen sentence sums it up
Man is the measure of all things of the things which are
that they are and of things which are not that they are not6
Protagoras gives wings to an idea that many ponder try our
hardest (or not try at all) we cannot break free of ourselvesmdashour
senses our viewpoints our values even our ldquostuffrdquo Te world is
our judgment and nothing more It does not await our judgment
it is our judgment Tere is no objective truth but only various
views from various places at various times by various people
Tings are not our measure but we are the measure of them
Hence Protagoras is the spokesman for relativism sometimescalled nonrealism or perspectivism It is not just that we have no
(or limited) access to objective reality Tat is skepticism Reality
is pretty much exhausted by our perceptions and thoughts Te
real world is our world Myriads have measured Protagoras

wisdom can ignore him His ghost haunts us still Is there a phil-

students to live this waymdashfor their sakes and mine (It makes for
better papers too) Tus said Socrates the gadfly (or pain-in-
the-neck) of ancient Athens Like Protagoras we know of
Socrates through those who knew his work but unlike Pro-
tagoras we have more substantial sources particularly Plato
And Socrates is a household name Not incidentally the man
who was not an author ended up being the inspiration for the
prolific Plato who was the worldrsquos first systematic philosopher
As philosopher Alfred North Whitehead discerned ldquoTe safestgeneral characterization of the European philosophical tradition
is that it consists of a series of footnotes to Platordquo7 Te footnotes
may praise (Augustine) or blame (Aristotle) but footnotes are
everywhere as well as entire volumes
aking up Socratesrsquos philosophical challenge means exam-
ining just what his famous sentence means in itself and what it
means for us What might an examined life be given the distrac-
tions and overstimulation of postmodern times For Socrates
there is a way to calm the mind and search things out But is
there a place for Socratic dialogue today outside the Socratic
method of many law schools Further old Plato Socratesrsquos
chronicler and student may offer us wisdom pertaining to the
nagging questions of philosophy as he spurns the work of the philodoxers (lovers of opinion) and promotes the call of the phi-
losophers (lovers of wisdom) Worse yet were the misologists (one
of the Platonic corpusrsquos most winning words) those who took an
active role in hating the use of reason itself We may find some
today even in educated enclaves or even on the bestsellers lists
But one can also find Aristotle in popular bookstores always
in the philosophy section (along with less prestigious volumes
such as Led Zeppelin and Philosophy which we must pass over
without further comment) When Aristotle wrote ldquoAll men by
nature desire to knowrdquo he did not mean just the scholars or

teachers but ldquomanrdquomdashthe human race in all its circumstances and
variations Tat means every person whatever social standing
vocation or intelligence Although Aristotle was no egalitarian
(he thought that women were inferior to men and that some were
born to be slaves) he nevertheless appeals to a universal human
condition the desire to get reality right in the time that we have
Augustine the first great Christian philosopher like Socrates
before him strikes a personal note concerning getting reality
right Having examined himself and the leading philosophies ofhis day (including Plato and his footnotes) he confesses with a
cry of the heart addressed to God ldquoYou have made us for
yourself and restless is our heart until it comes to rest in yourdquo
Tis cry is not commonplace as in ldquoMy spirituality gives me
meaningrdquo It is instead the beginning of an argument told in his
autobiography In fact it may be the first autobiography on
record It is no doubt the first philosophical autobiography (if
we exclude the book of Ecclesiastes) Te irascible Jean-Jacques
Rousseau is well known for his autobiography as well but a short
book can only do so much8
Skipping madly over much philosophical history (without any
irreverence or glibness) we arrive at Reneacute Descartes the much
maligned but seldom understood ldquofather of modern philosophyrdquoDescartes was troubled by opinions without backingmdashthose
ideas about ultimate matters untethered from certainty Skep-
ticism was his foe as it is in one way or another for any philos-
opher Tis is because the question arises How do you know
what you claim to know Mere social position or historical tra-
dition will not cinch the deal for this philosopher and scientist
In our language (which itself needs interrogation) the man

edgeable answer it should not be the default response according
to Descartes Tis apprehension led him on a quest that began

with himself Like Augustine but in briefer scope he put this in
autobiographical form in Discourse on Method and to some
extent in Meditations on First Philosophy But Descartesrsquos quest
did not end with himself unlike so much contemporary self-
help literature He is famous for the sentence ldquoI think therefore
I amrdquo But God himself has something to do with that sentence
For Descartes there was no leap of faith in it either Reason was
the guide But how far can reason take us
A contemporary of Descartes had an idea ldquoTe heart has itsreasons that reason knows nothing ofrdquo wrote Blaise Pascal who
was the best phrasemaker of the lot of our philosophers Tis
statement is a window into a worldview Humans have the ca-
pacity to calculate and reason methodically but they may also
know some things by tracing out the contours and resources of
ldquothe heartrdquomdashanother organ of knowledge Philosophers study
many thinkers but few come to love few of them (My graduate
seminar on Kantrsquos Critique of Pure Reason was well worth it but
was no love affair) Pascal on the contrary is much loved by many
He is so loved that people even love things he never actually said
such as ldquoTere is a God-shaped vacuum that only God can fillrdquo
But this paraphrase is not far off the mark though it should be
placed within a larger perspective of Pascalrsquos philosophyTe French polymathrsquos philosophy is far more fascinating than
the CliffsNotes version allows Pascal did not put faith in place
of reason and he was not a one-trick philosopher (Pascalrsquos
wager) Slander and libel have fouled the air about him ob-
scuring his sophisticated treatment of the cost-benefit sense of
believing in religion or not Yet he was neither knave nor poser
Te founder of probability theory and the inventor of the first
working calculating machine had reasons for faith Like Des-
cartes he was bugged by skepticism and like Descartes he ap-
pealed to human nature as a place to start the discussion

but it opens a door of inquiry for us
Te greatest hazard of all losing onersquos self can occur very
quietly in the world as if it were nothing at all
It was penned by an idiosyncratic and famously melancholy
Dane named Soslashren Kierkegaard a philosopher intensely inter-
ested in the self in relation to ultimate reality Tis should sound
familiar since all philosophers have expressed this interest inone way or another But Kierkegaardrsquos way was in a sense as
much psychological as philosophical He intrepidly limned the
inner workings of the self of consciousness in philosophical
categories Like Pascal Kierkegaard wanted to strip away
through existential analysis the layers and dynamics of the self
that keep reality at bay Unlike Pascal and the other philosophers
he was more interested in the analysis of the self than presentingit with arguments for an abstract objective reality Tis may
sound a bit unphilosophical but it is not But that takes time to
tease out properly as I hope you will see
Our seven sentences may be viewed as several doors into
worlds previously unknown Or they may be our irritants to
prod us to move away from facile factoidsmdashldquoDo your own thingrdquoldquoFollow your blissrdquo ldquoKeep Calm and Carry Onrdquomdashto more so-
bering reflections9 Perhaps the sentences are bridges to other
lands of thought Tese philosophical sentences do not sum the
thought of any of the philosophers for these thinkers are far too
deep for that Nor do the seven sentences aim to summarize the
history of philosophy Tat would be a pompous and laughable
claim Some things cannot be put into a nutshell including thenutshell itself But I claim that philosophical activity can be
sparked by just seven sterling sentencesmdashand who knows where

PROTAGORAS
Man is the measure of all things
P
Greeks could do philosophy Te basic questions of exis-
tence have never been far from the human mind but the
ancient Greeks excelled at this and their musingsmdashsome frag-
mentary or secondhandmdashhave been preserved in written texts
However much philosophy occurred in exclusively oral cultures
the Greeks valued writing in addition to oral memory and tra-
dition Socrates you remember wrote nothing but generated a vast literature though his dialogues A lesser-known figure who
came after him did write a few things and his famous adage is
worth considering
Protagoras (fifth century BC) is not to be confused with
like-sounding ancient Greek thinkers named Pythagoras or
Parmenides who along with others were pre-Socratic thinkers
(Tis shows the significance of Socrates since philosophy isdated with respect to his life) Tese thinkers are worth inter-
rogating as well and I studied them with profit in a year-long
course in ancient philosophy forty years ago Protagoras

stands out to us though because of his adage about absolute
assessment
Man is the measure of all things of the things which are
that they are and of things which are not that they are not1
His claim is not simply that people measure thingsmdashsuch as
character chariots boats and fishmdashbut that each human is the
measure Each person is the assessment or judgment What
could this mean No person is a slide ruler or scale or Geigercounter although we avail ourselves of such things

We tend to think that people use a standard of measurement
outside of themselves Even inadequate and one-dimensional
measures such as onersquos IQ score are not determined by how we
feel about themmdashand Mensa is very picky about thisOn the other hand Protagoras has Shakespearersquos Hamlet on
his side at least concerning morality ldquoFor there is nothing either
good or bad but thinking makes it sordquo2 Tat is morals do not
have objective standing rather they are judged differently by
different people Tis quote is from a discussion about Denmark
which Hamlet unlike his interlocutor Rosencrantz said was ldquoaprisonrdquo If Hamlet is right then both Hamlet and Rosencrantz
are right about Denmark
What then was Protagorasrsquos point (Wersquoll put serious Shake-
spearian interpretation aside) o find out we need to take a step
back into the Greek philosophical scene and not rush to
judgmentmdashor rush to endorsement either Protagoras would ap-
prove of this deliberationProtagoras was considered the chief of the Sophists intellec-
tuals who were paid to defend the views of their sponsors Tey

term sophist meant something like our ldquoprofessorrdquo but later a
Sophist was deemed a hired gun a philosopher for hire and one
having no principles of his own Teir arguments supposedly
were merely the instruments of the will of their bosses One may
argue over the virtues of the Sophists but it is certainly not true
that being paid for philosophizing necessarily disqualifies the
employeersquos arguments On the other hand if we think of a
Sophist as something like a political speech writer or the like

Protagoras was one of a spirited group of fastidious thinkers
who tired or at least grew skeptical of Greek mythology with
its pantheon of gods Yes the stories of the gods were often riv-
eting and worth repeating A recent volume by Luc Ferry is
called Te Wisdom of the Myths How Greek Mythology Can
Change Your Life3 Tere was always a moral to the story Her-
cules the last son of Zeus was a dashing and dramatic character
who started as a mighty mortal and became a god upon deathAlthough a bit impetuous and lacking in sobriety he plays well
as a hero Zeus himself is the apotheosis of power but acts
largely without moral authority Even the might of Zeus does not
support the idea that ldquomight makes rightrdquo since might may make
for divine mischief My point is not to survey or psychoanalyze
the denizens of Greek mythology but to make a general point
Mythologies may inspire and guide to some extent our relation
to the hard facts of family life death and sexuality (and some of
the gods tended to be naughty in this way)
Nevertheless the problem with Greek mythology (or any

mythology Eastern or Western) is simply that it is mythology it
is neither history nor clearly articulated philosophy In too many
ways the gods despite their thespian reacutesumeacutes and magical
powers were not much more than semi- glorified mortals Tis
was the objection of a growing group of Greeks who were mere
mortalsmdashmortals with meaning metaphysics and morality on
their minds And what might the mind do when free to explore
life and its questions apart from the venerable stories of Greek
fascination It might philosophize and so it didProtagoras and his cohorts quested for explanations of a more
abstract but also compelling sort than the old tales could afford
Tey sought principles to explain facts in a universal and logi-
cally coherent manner o be a little unfair to the mythologies
consider the tooth fairy She adds some magical benevolence to
the loss and placement of a baby tooth for children but the fairy
story adds nothing about the nature of benevolence the signifi-
cance of teeth or the significance of the humans who grow and
lose these teeth whether through development (teething) or
decay (the toothless)
Tus to give one example Tales of Miletus tried to find a
cosmic commonality to all things He divined it as water Yes
water which was more than rain oceans lakes and puddles Itwas everywhere so perhaps it was the root and branch of every-
thing Water or moisture in general lives in the clouds in plants
in animals (aquatic land or amphibious) and in thirsty mortals
It condenses and evaporates but never leaves the planet Con-
sidering the presence and power of water Tales extrapolated
that water was more than one more thing on earth however
necessary for life It was rather the unifying principle for exis-
tence Whatever we think of Tales his thinking is not absurd
and it indicates a thirst for philosophical explanation as opposed
to mythological meanderings At least he was trying

Protagoras

But it is Protagoras who calls for our attention Instead of ar-guing for something at the heart of everything (water for Tales)
a principle found in nature Protagoras moved back from nature
to the self After all skeptics had questioned mere mortalsrsquo
ability to know with any confidence what is out there inde-
pendent of themselves Te jaundiced eye sees things differently
from the nonjaundiced eye Children perceive entities invisible
to adults Adults sometimes hallucinatemdashbut perhaps they areseeing what most miss One woman feels cold in a room of degF
and another feels hot Age alters hearing seeing memory and
may jangle judgments Te upshot is that we cannot find a place
to stand to see the world as it is We are simply ill-equipped to
do so Objective truth what is independent of our perceptions
endlessly and mercilessly eludes us
We will return to skepticism when discussing Descartes and
Pascal but Protagoras was not a skeptic He did not withhold
judgments about facts in themselves because we do not have the
ability to know them While recognizing that the skeptics had
dethroned our intellectual confidence in capturing objective re-
ality his point of departure was this we do know our own view-
points judgments and beliefs Tat is we measure things theydo not measure themselves So I take most of Francis Baconrsquos
paintings to be ugly and thus unattractive I am repulsed Tis is
the end of the story or my story Tis is my measurement You
on the contrary may find delight in Baconrsquos tortured figures and
color schemes Tat is your measurement and the end of your
story
Now reconsider the skeptical point made earlier One person
can deem the room cold and another hot Te skeptic might say
we cannot know then what the room is given the variability in
perception But Protagoras claims that the room is hot for person

A and not hot for person B Tere is no contradiction since we
are considering individual perceptions Tere are two measure-
ments each of which is valid Tus Bacon is barbaric to me and
beautiful to youmdashand that is the level best we can do Or perhaps
I will come to adore Baconrsquos paintings and heap scorn on my
former judgment If so then that is my measurement
Tis is rather attractive at first blush After all there is no
dispute in matters of taste or to be more snobby De gustibus
non est disputandum Te avant-garde saxophone playing ofPeter Broumltzmann can send me into the upper reaches of aes-
thetic delight while sending others scurrying from the room
while covering their ears But Protagoras took this insight far
beyond artistic judgments Notice the reference range (or extent)
of Protagorasrsquos statement ldquoMan is the measure of all thingsrdquomdash
matters of taste as well as matters of fact matters of principle
and matters of matter Nothing is excluded
Let us follow this out As we think it through the old Greek
will sound much like modern man If Protagoras is right then
there is no disputing matters of morality either Man is the
measure of what is right and what is wrong what is virtuous and
what is vicious what should be loved and what should be hatedmdash
just as Hamlet claimed oday this thinking is usually put in thelanguage of choice instead of measurement but the idea is the
same If you chose to do X that choice is the end of the matter
Or to suit Protagoras if you measure X as worth doing then it
is worth doing Tis is true whether X refers to sailing stealing
or stampeding cattle in the direction of a Cub Scout outing
But we might say ldquoWho is to judgerdquo Who of us can stand
above him- or herself and others and become objective Yes we
recoil from some ideasmdashsuch as torturing the innocent merely
for pleasure or female genital mutilation But what does that tell
us about reality if there really is such a thing as reality Te claim

that ldquoman is the measure of all thingsrdquo is an all-encompassing
judgment itself Te answer to ldquoWho is to judgerdquo is that we are

Besides being a serial killer ed Bundy was a philosophical

Moral Philosophy Bundy said
I learned that all moral judgments are ldquovalue judgmentsrdquo
that all value judgments are subjective and that none can
be proved to be either ldquorightrdquo or ldquowrongrdquo I even read some-where that the Chief Justice of the United States had written
that the American Constitution expressed nothing more
than collective value judgments Believe it or not I figured
out for myselfmdashwhat apparently the Chief Justice couldnrsquot
figure out for himselfmdashthat if the rationality of one value
judgment was zero multiplying it by millions would not
make it one whit more rational Nor is there any ldquoreasonrdquo
to obey the law for anyone like myself who has the
boldness and daring ldquothe strength of characterrdquo to throw
off its shackles
I discovered that to become truly free truly unfettered
I had to become truly uninhibited And I quickly discovered
that the greatest obstacle to my freedom the greatest blockand limitation to it consists in the insupportable ldquovalue

When teaching ethics to undergraduates at a secular school I

historymdashthe philosophy that allowed and even impelled hisegregious crimes Next I ask them to reconsider their judg-

us and nothing beneath us It is all merely neutral and we make

on this basis But a statement cannot be true unless it accords
with the way the world in fact is and the way we in fact are Pro-
tagoras does capture some truths about perspective For ex-
ample my tastes in food determine how I measure the goodness
of the food I am the measure of that at least It matters nothing
whether a connoisseur thinks me an ignoramus I can only
measure it by what I experience at the moment In that way I am
the measure but am I the expert Am I the knowerTere is a strange implication for Protagorasrsquos view In the
Teaetetus Protagoras even states that error is impossible5 Al-
though he was a teacher he cannot by his own lights teach
anyone o this Socrates inquires
If whatever the individual judges by means of perception is
true for him if no man can assess anotherrsquos experiencebetter than he or can claim authority to examine another
manrsquos judgment and see if it be right or wrong if as we
have repeatedly said only the individual himself can judge
of his own world and what he judges is always true and
correct how could it ever be my friend that Protagoras
was a wise man so wise as to think himself fit to be the
teacher of other men and worth large fees while we in
comparison with him the ignorant ones needed to go and
sit at his feetmdashwe who are ourselves each the measure of
his own wisdom6

be written in Chinese or in English Since each language uses
different symbols for writing its graphic inscription for cat will
differ Tis is true for voicing the word cat as well Trough a
long messy process not instigated by any central planning each
culture selects its own conventions of communication Are not
these two systems of writing measuring reality in very different
ways In point of fact they are not
Both kinds of writing systems (as well as other means ofcommunication) make claims about a reality that are outside
of the systems themselves and outside of the individuals who
use the pictographic or ideographic methods We tacitly saw
this earlier But in both cases a cat is invoked there is a single
referent Te differences in linguistic custom are not differ-
ences in content A cat is a cat in whatever language and it will
not bark however it may be measured Moreover while it may
be vexing in places one can translate a book from English to
Chinese Not everything is lost in translation in fact more is
found than is lost ranslators need have no fear of losing their
livelihood
Staying on matters of taste for a moment (and not morality

same as when you became an adult You may still enjoy and

ciate it more deeply now If so (and substitute your own ex-
amples here if needed) your tastes have at least changed and

pectedly) childish Te apostle Paul notes this in a well-known
turn of phrase ldquoWhen I was a child I talked like a child I
thought like a child I reasoned like a child When I became a

Furthermore the very notion of improvement or progress
(not merely some change in quality) requires and assumes an
objective standard by which to measure improvement (or de-cline) If a baseball batter hits in and in he
has improved based on the best possible average of Tere
is a measurement and it is not the perception of the batter that
determines this measurement Tis is the case in the arts as well
Few knowledgeable about jazz would dispute that John Col-
tranersquos saxophone work improved during his tenure with pianist
Telonious Monkrsquos quartet or that it developed further in Col-
trane own ldquoclassic quartetrdquo (ndash)7 Here the assessment is
not quantitative or statistical but qualitative One might object
that this is a purely subjective judgment (such as whether one
feels hot or not) which is relative to the person hearing Who is
to judge Te answer is straightforward the one whose expe-
rience knowledge and wisdom merit approval Although manydrink wine there are few expert wine tasters A student of mine
is so adept at this art that he can tell what part of the country a
wine came from Not having developed this advanced degree of
skill this is foreign to me However I had no inclination to say
that my judgment on wine is as accurate as Markrsquos Along these
lines I was once embarrassed when one of my students told me
that the wine I was enjoying was ldquothe Kenny G of winesrdquo Tis as
jazz aficionados know was not a compliment about the wine or
about my taste for wine

But Herodotus may yet rescue Protagoras In his History the
ancient historian notes that Darius a king of ancient Persia (who
was a kind of premodern anthropologist because of his study of
cultural differences) called together some Greeks and askedthem what it would take to cannibalize their dead fathers Te
Greeks needed no time to ponder the proposition since nothing
would move them to such odious paternal desecration Teir
practice was cremation this alone would honor their dead Ten
Darius summoned several Callatians (from India) to join the
Greeks and asked them what would make them cremate their
deceased fathers Te Callatians were as horrified as the Greeks
had been and told Darius to not discuss such atrocities
Had Protagoras heard this he would likely applaud having
found more evidence for his outlook But not all applause is
earned While the Greeks and Callatians observed fundamen-
tally different funeral rites both cultures honored the dead Tat
is only particular practicesmdashnot just any old or new thingmdashwere esteemed right and good in the treatment of corpses and
these practices were not norms for the treatment of the living
In other words death was set apart as uniquely meaningful and
thus required that the living treat the dead with ritual respect
Tus Greeks and Callatians agreed on a deep principle of hon-
oring the dead Tey disagreed on the rule that stems from that
principle In no sense then does the example of cultural rela-
tivity disprove moral agreement across cultures since there was
deep agreement between the cultures C S Lewis makes just
this point in Mere Christianity

Protagoras
I know that some people say the idea of a Law of Nature or
decent behaviour known to all men is unsound because
different civilisations and different ages have had quite dif-
ferent moralities
But this is not true Tere have been differences between
their moralities but these have never amounted to any-
thing like a total difference If anyone will take the trouble
to compare the moral teaching of say the ancient Egyp-
tians Babylonians Hindus Chinese Greeks and Romanswhat will really strike him will be how very like they are to
each other and to our own9
Te case against Protagoras comes down to this If we want to
learn anything if we want to improve as human beings if we
want to condemn the ed Bundys of the world if we want any
kind of educated taste if we desire to understand and honorhumanity then we must reject the ldquoman is the measurerdquo theory
Each person is indeed the measurer of some things Some of
them the individual gets right some of them the individual gets
wrong And in this difference lies all the difference in the world
and even outside of it

students to live this waymdashfor their sakes and mine (It makes for
better papers too) Tus said Socrates the gadfly (or pain-in-
the-neck) of ancient Athens Like Protagoras we know of
Socrates through those who knew his work but unlike Pro-
tagoras we have more substantial sources particularly Plato
And Socrates is a household name Not incidentally the man
who was not an author ended up being the inspiration for the
prolific Plato who was the worldrsquos first systematic philosopher
As philosopher Alfred North Whitehead discerned ldquoTe safestgeneral characterization of the European philosophical tradition
is that it consists of a series of footnotes to Platordquo7 Te footnotes
may praise (Augustine) or blame (Aristotle) but footnotes are
everywhere as well as entire volumes
aking up Socratesrsquos philosophical challenge means exam-
ining just what his famous sentence means in itself and what it
means for us What might an examined life be given the distrac-
tions and overstimulation of postmodern times For Socrates
there is a way to calm the mind and search things out But is
there a place for Socratic dialogue today outside the Socratic
method of many law schools Further old Plato Socratesrsquos
chronicler and student may offer us wisdom pertaining to the
nagging questions of philosophy as he spurns the work of the philodoxers (lovers of opinion) and promotes the call of the phi-
losophers (lovers of wisdom) Worse yet were the misologists (one
of the Platonic corpusrsquos most winning words) those who took an
active role in hating the use of reason itself We may find some
today even in educated enclaves or even on the bestsellers lists
But one can also find Aristotle in popular bookstores always
in the philosophy section (along with less prestigious volumes
such as Led Zeppelin and Philosophy which we must pass over
without further comment) When Aristotle wrote ldquoAll men by
nature desire to knowrdquo he did not mean just the scholars or

teachers but ldquomanrdquomdashthe human race in all its circumstances and
variations Tat means every person whatever social standing
vocation or intelligence Although Aristotle was no egalitarian
(he thought that women were inferior to men and that some were
born to be slaves) he nevertheless appeals to a universal human
condition the desire to get reality right in the time that we have
Augustine the first great Christian philosopher like Socrates
before him strikes a personal note concerning getting reality
right Having examined himself and the leading philosophies ofhis day (including Plato and his footnotes) he confesses with a
cry of the heart addressed to God ldquoYou have made us for
yourself and restless is our heart until it comes to rest in yourdquo
Tis cry is not commonplace as in ldquoMy spirituality gives me
meaningrdquo It is instead the beginning of an argument told in his
autobiography In fact it may be the first autobiography on
record It is no doubt the first philosophical autobiography (if
we exclude the book of Ecclesiastes) Te irascible Jean-Jacques
Rousseau is well known for his autobiography as well but a short
book can only do so much8
Skipping madly over much philosophical history (without any
irreverence or glibness) we arrive at Reneacute Descartes the much
maligned but seldom understood ldquofather of modern philosophyrdquoDescartes was troubled by opinions without backingmdashthose
ideas about ultimate matters untethered from certainty Skep-
ticism was his foe as it is in one way or another for any philos-
opher Tis is because the question arises How do you know
what you claim to know Mere social position or historical tra-
dition will not cinch the deal for this philosopher and scientist
In our language (which itself needs interrogation) the man

with himself Like Augustine but in briefer scope he put this in
autobiographical form in Discourse on Method and to some
extent in Meditations on First Philosophy But Descartesrsquos quest
did not end with himself unlike so much contemporary self-
help literature He is famous for the sentence ldquoI think therefore
I amrdquo But God himself has something to do with that sentence
For Descartes there was no leap of faith in it either Reason was
the guide But how far can reason take us
A contemporary of Descartes had an idea ldquoTe heart has itsreasons that reason knows nothing ofrdquo wrote Blaise Pascal who
was the best phrasemaker of the lot of our philosophers Tis
statement is a window into a worldview Humans have the ca-
pacity to calculate and reason methodically but they may also
know some things by tracing out the contours and resources of
ldquothe heartrdquomdashanother organ of knowledge Philosophers study
many thinkers but few come to love few of them (My graduate
seminar on Kantrsquos Critique of Pure Reason was well worth it but
was no love affair) Pascal on the contrary is much loved by many
He is so loved that people even love things he never actually said
such as ldquoTere is a God-shaped vacuum that only God can fillrdquo
But this paraphrase is not far off the mark though it should be
placed within a larger perspective of Pascalrsquos philosophyTe French polymathrsquos philosophy is far more fascinating than
the CliffsNotes version allows Pascal did not put faith in place
of reason and he was not a one-trick philosopher (Pascalrsquos
wager) Slander and libel have fouled the air about him ob-
scuring his sophisticated treatment of the cost-benefit sense of
believing in religion or not Yet he was neither knave nor poser
Te founder of probability theory and the inventor of the first
working calculating machine had reasons for faith Like Des-
cartes he was bugged by skepticism and like Descartes he ap-
pealed to human nature as a place to start the discussion

Philosophy in Only Seven Sentences
Our last sentence is not as well known as the previous ones
but it opens a door of inquiry for us
Te greatest hazard of all losing onersquos self can occur very
quietly in the world as if it were nothing at all
It was penned by an idiosyncratic and famously melancholy
Dane named Soslashren Kierkegaard a philosopher intensely inter-
ested in the self in relation to ultimate reality Tis should sound
familiar since all philosophers have expressed this interest inone way or another But Kierkegaardrsquos way was in a sense as
much psychological as philosophical He intrepidly limned the
inner workings of the self of consciousness in philosophical
categories Like Pascal Kierkegaard wanted to strip away
through existential analysis the layers and dynamics of the self
that keep reality at bay Unlike Pascal and the other philosophers
he was more interested in the analysis of the self than presentingit with arguments for an abstract objective reality Tis may
sound a bit unphilosophical but it is not But that takes time to
tease out properly as I hope you will see
Our seven sentences may be viewed as several doors into
worlds previously unknown Or they may be our irritants to
prod us to move away from facile factoidsmdashldquoDo your own thingrdquoldquoFollow your blissrdquo ldquoKeep Calm and Carry Onrdquomdashto more so-
bering reflections9 Perhaps the sentences are bridges to other
lands of thought Tese philosophical sentences do not sum the
thought of any of the philosophers for these thinkers are far too
deep for that Nor do the seven sentences aim to summarize the
history of philosophy Tat would be a pompous and laughable
claim Some things cannot be put into a nutshell including thenutshell itself But I claim that philosophical activity can be
sparked by just seven sterling sentencesmdashand who knows where
it might lead

PROTAGORAS
Man is the measure of all things
P
Greeks could do philosophy Te basic questions of exis-
tence have never been far from the human mind but the
ancient Greeks excelled at this and their musingsmdashsome frag-
mentary or secondhandmdashhave been preserved in written texts
However much philosophy occurred in exclusively oral cultures
the Greeks valued writing in addition to oral memory and tra-
dition Socrates you remember wrote nothing but generated a vast literature though his dialogues A lesser-known figure who
came after him did write a few things and his famous adage is

Sophist was deemed a hired gun a philosopher for hire and one
having no principles of his own Teir arguments supposedly
were merely the instruments of the will of their bosses One may
argue over the virtues of the Sophists but it is certainly not true

Protagoras was one of a spirited group of fastidious thinkers
who tired or at least grew skeptical of Greek mythology with
its pantheon of gods Yes the stories of the gods were often riv-
eting and worth repeating A recent volume by Luc Ferry is
called Te Wisdom of the Myths How Greek Mythology Can
Change Your Life3 Tere was always a moral to the story Her-
cules the last son of Zeus was a dashing and dramatic character
who started as a mighty mortal and became a god upon deathAlthough a bit impetuous and lacking in sobriety he plays well
as a hero Zeus himself is the apotheosis of power but acts
largely without moral authority Even the might of Zeus does not
support the idea that ldquomight makes rightrdquo since might may make
for divine mischief My point is not to survey or psychoanalyze
the denizens of Greek mythology but to make a general point
Mythologies may inspire and guide to some extent our relation
to the hard facts of family life death and sexuality (and some of
the gods tended to be naughty in this way)
Nevertheless the problem with Greek mythology (or any

mythology Eastern or Western) is simply that it is mythology it
is neither history nor clearly articulated philosophy In too many
ways the gods despite their thespian reacutesumeacutes and magical
powers were not much more than semi- glorified mortals Tis
was the objection of a growing group of Greeks who were mere
mortalsmdashmortals with meaning metaphysics and morality on
their minds And what might the mind do when free to explore
life and its questions apart from the venerable stories of Greek
fascination It might philosophize and so it didProtagoras and his cohorts quested for explanations of a more
abstract but also compelling sort than the old tales could afford
Tey sought principles to explain facts in a universal and logi-
cally coherent manner o be a little unfair to the mythologies
consider the tooth fairy She adds some magical benevolence to
the loss and placement of a baby tooth for children but the fairy
story adds nothing about the nature of benevolence the signifi-
cance of teeth or the significance of the humans who grow and
lose these teeth whether through development (teething) or
decay (the toothless)
Tus to give one example Tales of Miletus tried to find a
cosmic commonality to all things He divined it as water Yes
water which was more than rain oceans lakes and puddles Itwas everywhere so perhaps it was the root and branch of every-
thing Water or moisture in general lives in the clouds in plants
in animals (aquatic land or amphibious) and in thirsty mortals
It condenses and evaporates but never leaves the planet Con-
sidering the presence and power of water Tales extrapolated
that water was more than one more thing on earth however
necessary for life It was rather the unifying principle for exis-
tence Whatever we think of Tales his thinking is not absurd
and it indicates a thirst for philosophical explanation as opposed
to mythological meanderings At least he was trying

But it is Protagoras who calls for our attention Instead of ar-guing for something at the heart of everything (water for Tales)
a principle found in nature Protagoras moved back from nature
to the self After all skeptics had questioned mere mortalsrsquo
ability to know with any confidence what is out there inde-
pendent of themselves Te jaundiced eye sees things differently
from the nonjaundiced eye Children perceive entities invisible
to adults Adults sometimes hallucinatemdashbut perhaps they areseeing what most miss One woman feels cold in a room of degF
and another feels hot Age alters hearing seeing memory and
may jangle judgments Te upshot is that we cannot find a place
to stand to see the world as it is We are simply ill-equipped to
do so Objective truth what is independent of our perceptions
endlessly and mercilessly eludes us
We will return to skepticism when discussing Descartes and
Pascal but Protagoras was not a skeptic He did not withhold
judgments about facts in themselves because we do not have the
ability to know them While recognizing that the skeptics had
dethroned our intellectual confidence in capturing objective re-
ality his point of departure was this we do know our own view-
points judgments and beliefs Tat is we measure things theydo not measure themselves So I take most of Francis Baconrsquos
paintings to be ugly and thus unattractive I am repulsed Tis is
the end of the story or my story Tis is my measurement You
on the contrary may find delight in Baconrsquos tortured figures and
color schemes Tat is your measurement and the end of your
story
Now reconsider the skeptical point made earlier One person
can deem the room cold and another hot Te skeptic might say
we cannot know then what the room is given the variability in
perception But Protagoras claims that the room is hot for person

A and not hot for person B Tere is no contradiction since we
are considering individual perceptions Tere are two measure-
ments each of which is valid Tus Bacon is barbaric to me and
beautiful to youmdashand that is the level best we can do Or perhaps
I will come to adore Baconrsquos paintings and heap scorn on my
former judgment If so then that is my measurement
Tis is rather attractive at first blush After all there is no
dispute in matters of taste or to be more snobby De gustibus
non est disputandum Te avant-garde saxophone playing ofPeter Broumltzmann can send me into the upper reaches of aes-
thetic delight while sending others scurrying from the room
while covering their ears But Protagoras took this insight far
beyond artistic judgments Notice the reference range (or extent)
of Protagorasrsquos statement ldquoMan is the measure of all thingsrdquomdash
matters of taste as well as matters of fact matters of principle
and matters of matter Nothing is excluded
Let us follow this out As we think it through the old Greek
will sound much like modern man If Protagoras is right then
there is no disputing matters of morality either Man is the
measure of what is right and what is wrong what is virtuous and
what is vicious what should be loved and what should be hatedmdash
just as Hamlet claimed oday this thinking is usually put in thelanguage of choice instead of measurement but the idea is the
same If you chose to do X that choice is the end of the matter
Or to suit Protagoras if you measure X as worth doing then it
is worth doing Tis is true whether X refers to sailing stealing
or stampeding cattle in the direction of a Cub Scout outing
But we might say ldquoWho is to judgerdquo Who of us can stand
above him- or herself and others and become objective Yes we
recoil from some ideasmdashsuch as torturing the innocent merely
for pleasure or female genital mutilation But what does that tell
us about reality if there really is such a thing as reality Te claim

that ldquoman is the measure of all thingsrdquo is an all-encompassing
judgment itself Te answer to ldquoWho is to judgerdquo is that we are
the measure of all things Tat is there is nothing outside of

Besides being a serial killer ed Bundy was a philosophical

was one of dozens of his prey As reported in Louis Pojmanrsquos text
Moral Philosophy Bundy said
I learned that all moral judgments are ldquovalue judgmentsrdquo
that all value judgments are subjective and that none can
be proved to be either ldquorightrdquo or ldquowrongrdquo I even read some-where that the Chief Justice of the United States had written
that the American Constitution expressed nothing more
than collective value judgments Believe it or not I figured
out for myselfmdashwhat apparently the Chief Justice couldnrsquot
figure out for himselfmdashthat if the rationality of one value
judgment was zero multiplying it by millions would not
make it one whit more rational Nor is there any ldquoreasonrdquo
to obey the law for anyone like myself who has the
boldness and daring ldquothe strength of characterrdquo to throw
off its shackles
I discovered that to become truly free truly unfettered
I had to become truly uninhibited And I quickly discovered
that the greatest obstacle to my freedom the greatest blockand limitation to it consists in the insupportable ldquovalue

When teaching ethics to undergraduates at a secular school I
often hand out this Bundy quotation but without identifying the

philosophy of one of the most infamous serial killers in American
historymdashthe philosophy that allowed and even impelled hisegregious crimes Next I ask them to reconsider their judg-

dents show dismay and surprise that they were in agreement

us and nothing beneath us It is all merely neutral and we make

on this basis But a statement cannot be true unless it accords
with the way the world in fact is and the way we in fact are Pro-
tagoras does capture some truths about perspective For ex-
ample my tastes in food determine how I measure the goodness
of the food I am the measure of that at least It matters nothing
whether a connoisseur thinks me an ignoramus I can only
measure it by what I experience at the moment In that way I am
the measure but am I the expert Am I the knowerTere is a strange implication for Protagorasrsquos view In the
Teaetetus Protagoras even states that error is impossible5 Al-
though he was a teacher he cannot by his own lights teach
anyone o this Socrates inquires
If whatever the individual judges by means of perception is
true for him if no man can assess anotherrsquos experiencebetter than he or can claim authority to examine another
manrsquos judgment and see if it be right or wrong if as we
have repeatedly said only the individual himself can judge
of his own world and what he judges is always true and
correct how could it ever be my friend that Protagoras
was a wise man so wise as to think himself fit to be the
teacher of other men and worth large fees while we in

sit at his feetmdashwe who are ourselves each the measure of

be written in Chinese or in English Since each language uses
different symbols for writing its graphic inscription for cat will
differ Tis is true for voicing the word cat as well Trough a
long messy process not instigated by any central planning each
culture selects its own conventions of communication Are not
these two systems of writing measuring reality in very different
ways In point of fact they are not
Both kinds of writing systems (as well as other means ofcommunication) make claims about a reality that are outside
of the systems themselves and outside of the individuals who
use the pictographic or ideographic methods We tacitly saw
this earlier But in both cases a cat is invoked there is a single
referent Te differences in linguistic custom are not differ-
ences in content A cat is a cat in whatever language and it will
not bark however it may be measured Moreover while it may
be vexing in places one can translate a book from English to
Chinese Not everything is lost in translation in fact more is

livelihood
Staying on matters of taste for a moment (and not morality

pectedly) childish Te apostle Paul notes this in a well-known
turn of phrase ldquoWhen I was a child I talked like a child I
thought like a child I reasoned like a child When I became a
man I put the ways of childhood behind merdquo ( Corinthians

Furthermore the very notion of improvement or progress
(not merely some change in quality) requires and assumes an
objective standard by which to measure improvement (or de-cline) If a baseball batter hits in and in he
has improved based on the best possible average of Tere
is a measurement and it is not the perception of the batter that
determines this measurement Tis is the case in the arts as well
Few knowledgeable about jazz would dispute that John Col-
tranersquos saxophone work improved during his tenure with pianist
Telonious Monkrsquos quartet or that it developed further in Col-
trane own ldquoclassic quartetrdquo (ndash)7 Here the assessment is
not quantitative or statistical but qualitative One might object
that this is a purely subjective judgment (such as whether one
feels hot or not) which is relative to the person hearing Who is
to judge Te answer is straightforward the one whose expe-
rience knowledge and wisdom merit approval Although manydrink wine there are few expert wine tasters A student of mine
is so adept at this art that he can tell what part of the country a
wine came from Not having developed this advanced degree of
skill this is foreign to me However I had no inclination to say
that my judgment on wine is as accurate as Markrsquos Along these
lines I was once embarrassed when one of my students told me
that the wine I was enjoying was ldquothe Kenny G of winesrdquo Tis as
jazz aficionados know was not a compliment about the wine or
about my taste for wine

But Herodotus may yet rescue Protagoras In his History the
ancient historian notes that Darius a king of ancient Persia (who
was a kind of premodern anthropologist because of his study of
cultural differences) called together some Greeks and askedthem what it would take to cannibalize their dead fathers Te
Greeks needed no time to ponder the proposition since nothing
would move them to such odious paternal desecration Teir
practice was cremation this alone would honor their dead Ten
Darius summoned several Callatians (from India) to join the
Greeks and asked them what would make them cremate their
deceased fathers Te Callatians were as horrified as the Greeks
had been and told Darius to not discuss such atrocities
Had Protagoras heard this he would likely applaud having
found more evidence for his outlook But not all applause is
earned While the Greeks and Callatians observed fundamen-
tally different funeral rites both cultures honored the dead Tat
is only particular practicesmdashnot just any old or new thingmdashwere esteemed right and good in the treatment of corpses and
these practices were not norms for the treatment of the living
In other words death was set apart as uniquely meaningful and
thus required that the living treat the dead with ritual respect
Tus Greeks and Callatians agreed on a deep principle of hon-
oring the dead Tey disagreed on the rule that stems from that
principle In no sense then does the example of cultural rela-
tivity disprove moral agreement across cultures since there was
deep agreement between the cultures C S Lewis makes just
this point in Mere Christianity

Protagoras
I know that some people say the idea of a Law of Nature or
decent behaviour known to all men is unsound because
different civilisations and different ages have had quite dif-
ferent moralities
But this is not true Tere have been differences between
their moralities but these have never amounted to any-
thing like a total difference If anyone will take the trouble
to compare the moral teaching of say the ancient Egyp-
tians Babylonians Hindus Chinese Greeks and Romanswhat will really strike him will be how very like they are to
each other and to our own9
Te case against Protagoras comes down to this If we want to
learn anything if we want to improve as human beings if we
want to condemn the ed Bundys of the world if we want any
kind of educated taste if we desire to understand and honorhumanity then we must reject the ldquoman is the measurerdquo theory
Each person is indeed the measurer of some things Some of
them the individual gets right some of them the individual gets
wrong And in this difference lies all the difference in the world
and even outside of it

variations Tat means every person whatever social standing
vocation or intelligence Although Aristotle was no egalitarian
(he thought that women were inferior to men and that some were
born to be slaves) he nevertheless appeals to a universal human
condition the desire to get reality right in the time that we have
Augustine the first great Christian philosopher like Socrates
before him strikes a personal note concerning getting reality
right Having examined himself and the leading philosophies ofhis day (including Plato and his footnotes) he confesses with a
cry of the heart addressed to God ldquoYou have made us for
yourself and restless is our heart until it comes to rest in yourdquo
Tis cry is not commonplace as in ldquoMy spirituality gives me
meaningrdquo It is instead the beginning of an argument told in his
autobiography In fact it may be the first autobiography on
record It is no doubt the first philosophical autobiography (if
we exclude the book of Ecclesiastes) Te irascible Jean-Jacques
Rousseau is well known for his autobiography as well but a short
book can only do so much8
Skipping madly over much philosophical history (without any
irreverence or glibness) we arrive at Reneacute Descartes the much
maligned but seldom understood ldquofather of modern philosophyrdquoDescartes was troubled by opinions without backingmdashthose
ideas about ultimate matters untethered from certainty Skep-

dition will not cinch the deal for this philosopher and scientist

with himself Like Augustine but in briefer scope he put this in
autobiographical form in Discourse on Method and to some
extent in Meditations on First Philosophy But Descartesrsquos quest
did not end with himself unlike so much contemporary self-
help literature He is famous for the sentence ldquoI think therefore
I amrdquo But God himself has something to do with that sentence
For Descartes there was no leap of faith in it either Reason was
the guide But how far can reason take us
A contemporary of Descartes had an idea ldquoTe heart has itsreasons that reason knows nothing ofrdquo wrote Blaise Pascal who
was the best phrasemaker of the lot of our philosophers Tis
statement is a window into a worldview Humans have the ca-
pacity to calculate and reason methodically but they may also
know some things by tracing out the contours and resources of
ldquothe heartrdquomdashanother organ of knowledge Philosophers study
many thinkers but few come to love few of them (My graduate
seminar on Kantrsquos Critique of Pure Reason was well worth it but
was no love affair) Pascal on the contrary is much loved by many
He is so loved that people even love things he never actually said
such as ldquoTere is a God-shaped vacuum that only God can fillrdquo
But this paraphrase is not far off the mark though it should be
placed within a larger perspective of Pascalrsquos philosophyTe French polymathrsquos philosophy is far more fascinating than
the CliffsNotes version allows Pascal did not put faith in place
of reason and he was not a one-trick philosopher (Pascalrsquos
wager) Slander and libel have fouled the air about him ob-
scuring his sophisticated treatment of the cost-benefit sense of
believing in religion or not Yet he was neither knave nor poser
Te founder of probability theory and the inventor of the first
working calculating machine had reasons for faith Like Des-
cartes he was bugged by skepticism and like Descartes he ap-
pealed to human nature as a place to start the discussion

Philosophy in Only Seven Sentences
Our last sentence is not as well known as the previous ones
but it opens a door of inquiry for us
Te greatest hazard of all losing onersquos self can occur very
quietly in the world as if it were nothing at all
It was penned by an idiosyncratic and famously melancholy
Dane named Soslashren Kierkegaard a philosopher intensely inter-
ested in the self in relation to ultimate reality Tis should sound
familiar since all philosophers have expressed this interest inone way or another But Kierkegaardrsquos way was in a sense as
much psychological as philosophical He intrepidly limned the
inner workings of the self of consciousness in philosophical
categories Like Pascal Kierkegaard wanted to strip away
through existential analysis the layers and dynamics of the self
that keep reality at bay Unlike Pascal and the other philosophers
he was more interested in the analysis of the self than presentingit with arguments for an abstract objective reality Tis may
sound a bit unphilosophical but it is not But that takes time to
tease out properly as I hope you will see
Our seven sentences may be viewed as several doors into
worlds previously unknown Or they may be our irritants to
prod us to move away from facile factoidsmdashldquoDo your own thingrdquoldquoFollow your blissrdquo ldquoKeep Calm and Carry Onrdquomdashto more so-
bering reflections9 Perhaps the sentences are bridges to other
lands of thought Tese philosophical sentences do not sum the
thought of any of the philosophers for these thinkers are far too
deep for that Nor do the seven sentences aim to summarize the
history of philosophy Tat would be a pompous and laughable
claim Some things cannot be put into a nutshell including thenutshell itself But I claim that philosophical activity can be
sparked by just seven sterling sentencesmdashand who knows where
it might lead

Man is the measure of all things
P
Greeks could do philosophy Te basic questions of exis-
tence have never been far from the human mind but the
ancient Greeks excelled at this and their musingsmdashsome frag-
mentary or secondhandmdashhave been preserved in written texts
However much philosophy occurred in exclusively oral cultures
the Greeks valued writing in addition to oral memory and tra-
dition Socrates you remember wrote nothing but generated a vast literature though his dialogues A lesser-known figure who
came after him did write a few things and his famous adage is
worth considering
Protagoras (fifth century BC) is not to be confused with

Sophist was deemed a hired gun a philosopher for hire and one

Protagoras was one of a spirited group of fastidious thinkers
who tired or at least grew skeptical of Greek mythology with
its pantheon of gods Yes the stories of the gods were often riv-
eting and worth repeating A recent volume by Luc Ferry is
called Te Wisdom of the Myths How Greek Mythology Can
Change Your Life3 Tere was always a moral to the story Her-
cules the last son of Zeus was a dashing and dramatic character
who started as a mighty mortal and became a god upon deathAlthough a bit impetuous and lacking in sobriety he plays well
as a hero Zeus himself is the apotheosis of power but acts
largely without moral authority Even the might of Zeus does not
support the idea that ldquomight makes rightrdquo since might may make
for divine mischief My point is not to survey or psychoanalyze
the denizens of Greek mythology but to make a general point
Mythologies may inspire and guide to some extent our relation
to the hard facts of family life death and sexuality (and some of
the gods tended to be naughty in this way)
Nevertheless the problem with Greek mythology (or any

mythology Eastern or Western) is simply that it is mythology it
is neither history nor clearly articulated philosophy In too many
ways the gods despite their thespian reacutesumeacutes and magical
powers were not much more than semi- glorified mortals Tis
was the objection of a growing group of Greeks who were mere
mortalsmdashmortals with meaning metaphysics and morality on
their minds And what might the mind do when free to explore
life and its questions apart from the venerable stories of Greek
fascination It might philosophize and so it didProtagoras and his cohorts quested for explanations of a more
abstract but also compelling sort than the old tales could afford
Tey sought principles to explain facts in a universal and logi-
cally coherent manner o be a little unfair to the mythologies
consider the tooth fairy She adds some magical benevolence to
the loss and placement of a baby tooth for children but the fairy
story adds nothing about the nature of benevolence the signifi-
cance of teeth or the significance of the humans who grow and
lose these teeth whether through development (teething) or
decay (the toothless)
Tus to give one example Tales of Miletus tried to find a
cosmic commonality to all things He divined it as water Yes
water which was more than rain oceans lakes and puddles Itwas everywhere so perhaps it was the root and branch of every-
thing Water or moisture in general lives in the clouds in plants
in animals (aquatic land or amphibious) and in thirsty mortals
It condenses and evaporates but never leaves the planet Con-
sidering the presence and power of water Tales extrapolated
that water was more than one more thing on earth however
necessary for life It was rather the unifying principle for exis-
tence Whatever we think of Tales his thinking is not absurd
and it indicates a thirst for philosophical explanation as opposed
to mythological meanderings At least he was trying

But it is Protagoras who calls for our attention Instead of ar-guing for something at the heart of everything (water for Tales)
a principle found in nature Protagoras moved back from nature
to the self After all skeptics had questioned mere mortalsrsquo
ability to know with any confidence what is out there inde-
pendent of themselves Te jaundiced eye sees things differently
from the nonjaundiced eye Children perceive entities invisible
to adults Adults sometimes hallucinatemdashbut perhaps they areseeing what most miss One woman feels cold in a room of degF
and another feels hot Age alters hearing seeing memory and
may jangle judgments Te upshot is that we cannot find a place
to stand to see the world as it is We are simply ill-equipped to
do so Objective truth what is independent of our perceptions
endlessly and mercilessly eludes us
We will return to skepticism when discussing Descartes and
Pascal but Protagoras was not a skeptic He did not withhold
judgments about facts in themselves because we do not have the
ability to know them While recognizing that the skeptics had
dethroned our intellectual confidence in capturing objective re-
ality his point of departure was this we do know our own view-
points judgments and beliefs Tat is we measure things theydo not measure themselves So I take most of Francis Baconrsquos
paintings to be ugly and thus unattractive I am repulsed Tis is
the end of the story or my story Tis is my measurement You
on the contrary may find delight in Baconrsquos tortured figures and
color schemes Tat is your measurement and the end of your
story
Now reconsider the skeptical point made earlier One person
can deem the room cold and another hot Te skeptic might say
we cannot know then what the room is given the variability in
perception But Protagoras claims that the room is hot for person

are considering individual perceptions Tere are two measure-
ments each of which is valid Tus Bacon is barbaric to me and
beautiful to youmdashand that is the level best we can do Or perhaps
I will come to adore Baconrsquos paintings and heap scorn on my
former judgment If so then that is my measurement
Tis is rather attractive at first blush After all there is no
dispute in matters of taste or to be more snobby De gustibus
non est disputandum Te avant-garde saxophone playing ofPeter Broumltzmann can send me into the upper reaches of aes-
thetic delight while sending others scurrying from the room
while covering their ears But Protagoras took this insight far
beyond artistic judgments Notice the reference range (or extent)
of Protagorasrsquos statement ldquoMan is the measure of all thingsrdquomdash
matters of taste as well as matters of fact matters of principle
and matters of matter Nothing is excluded
Let us follow this out As we think it through the old Greek
will sound much like modern man If Protagoras is right then
there is no disputing matters of morality either Man is the
measure of what is right and what is wrong what is virtuous and
what is vicious what should be loved and what should be hatedmdash
just as Hamlet claimed oday this thinking is usually put in thelanguage of choice instead of measurement but the idea is the
same If you chose to do X that choice is the end of the matter
Or to suit Protagoras if you measure X as worth doing then it
is worth doing Tis is true whether X refers to sailing stealing
or stampeding cattle in the direction of a Cub Scout outing
But we might say ldquoWho is to judgerdquo Who of us can stand
above him- or herself and others and become objective Yes we
recoil from some ideasmdashsuch as torturing the innocent merely
for pleasure or female genital mutilation But what does that tell
us about reality if there really is such a thing as reality Te claim

that ldquoman is the measure of all thingsrdquo is an all-encompassing
judgment itself Te answer to ldquoWho is to judgerdquo is that we are
the measure of all things Tat is there is nothing outside of
human judgment by which it might be judged But why would

Besides being a serial killer ed Bundy was a philosophical

was one of dozens of his prey As reported in Louis Pojmanrsquos text
Moral Philosophy Bundy said
I learned that all moral judgments are ldquovalue judgmentsrdquo
that all value judgments are subjective and that none can
be proved to be either ldquorightrdquo or ldquowrongrdquo I even read some-where that the Chief Justice of the United States had written
that the American Constitution expressed nothing more
than collective value judgments Believe it or not I figured
out for myselfmdashwhat apparently the Chief Justice couldnrsquot
figure out for himselfmdashthat if the rationality of one value
judgment was zero multiplying it by millions would not
make it one whit more rational Nor is there any ldquoreasonrdquo
to obey the law for anyone like myself who has the
boldness and daring ldquothe strength of characterrdquo to throw
off its shackles
I discovered that to become truly free truly unfettered
I had to become truly uninhibited And I quickly discovered
that the greatest obstacle to my freedom the greatest blockand limitation to it consists in the insupportable ldquovalue

When teaching ethics to undergraduates at a secular school I

on this basis But a statement cannot be true unless it accords
with the way the world in fact is and the way we in fact are Pro-
tagoras does capture some truths about perspective For ex-
ample my tastes in food determine how I measure the goodness
of the food I am the measure of that at least It matters nothing
whether a connoisseur thinks me an ignoramus I can only
measure it by what I experience at the moment In that way I am
the measure but am I the expert Am I the knowerTere is a strange implication for Protagorasrsquos view In the
Teaetetus Protagoras even states that error is impossible5 Al-
though he was a teacher he cannot by his own lights teach
anyone o this Socrates inquires
If whatever the individual judges by means of perception is
true for him if no man can assess anotherrsquos experiencebetter than he or can claim authority to examine another
manrsquos judgment and see if it be right or wrong if as we
have repeatedly said only the individual himself can judge

teacher of other men and worth large fees while we in

sit at his feetmdashwe who are ourselves each the measure of

be written in Chinese or in English Since each language uses
different symbols for writing its graphic inscription for cat will
differ Tis is true for voicing the word cat as well Trough a
long messy process not instigated by any central planning each
culture selects its own conventions of communication Are not
these two systems of writing measuring reality in very different
ways In point of fact they are not
Both kinds of writing systems (as well as other means ofcommunication) make claims about a reality that are outside
of the systems themselves and outside of the individuals who
use the pictographic or ideographic methods We tacitly saw
this earlier But in both cases a cat is invoked there is a single
referent Te differences in linguistic custom are not differ-
ences in content A cat is a cat in whatever language and it will
not bark however it may be measured Moreover while it may
be vexing in places one can translate a book from English to
Chinese Not everything is lost in translation in fact more is

pectedly) childish Te apostle Paul notes this in a well-known
turn of phrase ldquoWhen I was a child I talked like a child I
thought like a child I reasoned like a child When I became a
man I put the ways of childhood behind merdquo ( Corinthians

Furthermore the very notion of improvement or progress
(not merely some change in quality) requires and assumes an
objective standard by which to measure improvement (or de-cline) If a baseball batter hits in and in he
has improved based on the best possible average of Tere
is a measurement and it is not the perception of the batter that
determines this measurement Tis is the case in the arts as well
Few knowledgeable about jazz would dispute that John Col-
tranersquos saxophone work improved during his tenure with pianist
Telonious Monkrsquos quartet or that it developed further in Col-
trane own ldquoclassic quartetrdquo (ndash)7 Here the assessment is
not quantitative or statistical but qualitative One might object
that this is a purely subjective judgment (such as whether one
feels hot or not) which is relative to the person hearing Who is
to judge Te answer is straightforward the one whose expe-
rience knowledge and wisdom merit approval Although manydrink wine there are few expert wine tasters A student of mine
is so adept at this art that he can tell what part of the country a
wine came from Not having developed this advanced degree of
skill this is foreign to me However I had no inclination to say
that my judgment on wine is as accurate as Markrsquos Along these
lines I was once embarrassed when one of my students told me
that the wine I was enjoying was ldquothe Kenny G of winesrdquo Tis as
jazz aficionados know was not a compliment about the wine or
about my taste for wine

But Herodotus may yet rescue Protagoras In his History the
ancient historian notes that Darius a king of ancient Persia (who
was a kind of premodern anthropologist because of his study of
cultural differences) called together some Greeks and askedthem what it would take to cannibalize their dead fathers Te
Greeks needed no time to ponder the proposition since nothing
would move them to such odious paternal desecration Teir
practice was cremation this alone would honor their dead Ten
Darius summoned several Callatians (from India) to join the
Greeks and asked them what would make them cremate their
deceased fathers Te Callatians were as horrified as the Greeks
had been and told Darius to not discuss such atrocities
Had Protagoras heard this he would likely applaud having
found more evidence for his outlook But not all applause is
earned While the Greeks and Callatians observed fundamen-
tally different funeral rites both cultures honored the dead Tat
is only particular practicesmdashnot just any old or new thingmdashwere esteemed right and good in the treatment of corpses and
these practices were not norms for the treatment of the living
In other words death was set apart as uniquely meaningful and
thus required that the living treat the dead with ritual respect
Tus Greeks and Callatians agreed on a deep principle of hon-
oring the dead Tey disagreed on the rule that stems from that
principle In no sense then does the example of cultural rela-
tivity disprove moral agreement across cultures since there was
deep agreement between the cultures C S Lewis makes just
this point in Mere Christianity

Protagoras
I know that some people say the idea of a Law of Nature or
decent behaviour known to all men is unsound because
different civilisations and different ages have had quite dif-
ferent moralities
But this is not true Tere have been differences between
their moralities but these have never amounted to any-
thing like a total difference If anyone will take the trouble
to compare the moral teaching of say the ancient Egyp-
tians Babylonians Hindus Chinese Greeks and Romanswhat will really strike him will be how very like they are to
each other and to our own9
Te case against Protagoras comes down to this If we want to
learn anything if we want to improve as human beings if we
want to condemn the ed Bundys of the world if we want any
kind of educated taste if we desire to understand and honorhumanity then we must reject the ldquoman is the measurerdquo theory
Each person is indeed the measurer of some things Some of
them the individual gets right some of them the individual gets
wrong And in this difference lies all the difference in the world
and even outside of it

with himself Like Augustine but in briefer scope he put this in
autobiographical form in Discourse on Method and to some
extent in Meditations on First Philosophy But Descartesrsquos quest
did not end with himself unlike so much contemporary self-
help literature He is famous for the sentence ldquoI think therefore
I amrdquo But God himself has something to do with that sentence
For Descartes there was no leap of faith in it either Reason was
the guide But how far can reason take us
A contemporary of Descartes had an idea ldquoTe heart has itsreasons that reason knows nothing ofrdquo wrote Blaise Pascal who
was the best phrasemaker of the lot of our philosophers Tis
statement is a window into a worldview Humans have the ca-
pacity to calculate and reason methodically but they may also
know some things by tracing out the contours and resources of
ldquothe heartrdquomdashanother organ of knowledge Philosophers study
many thinkers but few come to love few of them (My graduate
seminar on Kantrsquos Critique of Pure Reason was well worth it but
was no love affair) Pascal on the contrary is much loved by many
He is so loved that people even love things he never actually said
such as ldquoTere is a God-shaped vacuum that only God can fillrdquo
But this paraphrase is not far off the mark though it should be
placed within a larger perspective of Pascalrsquos philosophyTe French polymathrsquos philosophy is far more fascinating than
the CliffsNotes version allows Pascal did not put faith in place
of reason and he was not a one-trick philosopher (Pascalrsquos
wager) Slander and libel have fouled the air about him ob-
scuring his sophisticated treatment of the cost-benefit sense of
believing in religion or not Yet he was neither knave nor poser
Te founder of probability theory and the inventor of the first
working calculating machine had reasons for faith Like Des-
cartes he was bugged by skepticism and like Descartes he ap-
pealed to human nature as a place to start the discussion

Philosophy in Only Seven Sentences
Our last sentence is not as well known as the previous ones
but it opens a door of inquiry for us
Te greatest hazard of all losing onersquos self can occur very
quietly in the world as if it were nothing at all
It was penned by an idiosyncratic and famously melancholy
Dane named Soslashren Kierkegaard a philosopher intensely inter-
ested in the self in relation to ultimate reality Tis should sound
familiar since all philosophers have expressed this interest inone way or another But Kierkegaardrsquos way was in a sense as
much psychological as philosophical He intrepidly limned the
inner workings of the self of consciousness in philosophical
categories Like Pascal Kierkegaard wanted to strip away
through existential analysis the layers and dynamics of the self
that keep reality at bay Unlike Pascal and the other philosophers
he was more interested in the analysis of the self than presentingit with arguments for an abstract objective reality Tis may
sound a bit unphilosophical but it is not But that takes time to
tease out properly as I hope you will see
Our seven sentences may be viewed as several doors into
worlds previously unknown Or they may be our irritants to
prod us to move away from facile factoidsmdashldquoDo your own thingrdquoldquoFollow your blissrdquo ldquoKeep Calm and Carry Onrdquomdashto more so-
bering reflections9 Perhaps the sentences are bridges to other
lands of thought Tese philosophical sentences do not sum the
thought of any of the philosophers for these thinkers are far too
deep for that Nor do the seven sentences aim to summarize the
history of philosophy Tat would be a pompous and laughable
claim Some things cannot be put into a nutshell including thenutshell itself But I claim that philosophical activity can be
sparked by just seven sterling sentencesmdashand who knows where
it might lead

PROTAGORAS
Man is the measure of all things
P
Greeks could do philosophy Te basic questions of exis-
tence have never been far from the human mind but the
ancient Greeks excelled at this and their musingsmdashsome frag-
mentary or secondhandmdashhave been preserved in written texts
However much philosophy occurred in exclusively oral cultures
the Greeks valued writing in addition to oral memory and tra-
dition Socrates you remember wrote nothing but generated a vast literature though his dialogues A lesser-known figure who
came after him did write a few things and his famous adage is
worth considering
Protagoras (fifth century BC) is not to be confused with
like-sounding ancient Greek thinkers named Pythagoras or
Parmenides who along with others were pre-Socratic thinkers
(Tis shows the significance of Socrates since philosophy isdated with respect to his life) Tese thinkers are worth inter-
rogating as well and I studied them with profit in a year-long
course in ancient philosophy forty years ago Protagoras

stands out to us though because of his adage about absolute
assessment
Man is the measure of all things of the things which are
that they are and of things which are not that they are not1
His claim is not simply that people measure thingsmdashsuch as
character chariots boats and fishmdashbut that each human is the
measure Each person is the assessment or judgment What
could this mean No person is a slide ruler or scale or Geigercounter although we avail ourselves of such things
W I M
We tend to think that people use a standard of measurement
outside of themselves Even inadequate and one-dimensional
measures such as onersquos IQ score are not determined by how we
feel about themmdashand Mensa is very picky about thisOn the other hand Protagoras has Shakespearersquos Hamlet on
his side at least concerning morality ldquoFor there is nothing either
good or bad but thinking makes it sordquo2 Tat is morals do not
have objective standing rather they are judged differently by
different people Tis quote is from a discussion about Denmark
which Hamlet unlike his interlocutor Rosencrantz said was ldquoaprisonrdquo If Hamlet is right then both Hamlet and Rosencrantz
are right about Denmark
What then was Protagorasrsquos point (Wersquoll put serious Shake-
spearian interpretation aside) o find out we need to take a step
back into the Greek philosophical scene and not rush to
judgmentmdashor rush to endorsement either Protagoras would ap-
prove of this deliberationProtagoras was considered the chief of the Sophists intellec-

Protagoras
D W D R
But it is Protagoras who calls for our attention Instead of ar-guing for something at the heart of everything (water for Tales)
a principle found in nature Protagoras moved back from nature
to the self After all skeptics had questioned mere mortalsrsquo
ability to know with any confidence what is out there inde-
pendent of themselves Te jaundiced eye sees things differently
from the nonjaundiced eye Children perceive entities invisible
to adults Adults sometimes hallucinatemdashbut perhaps they areseeing what most miss One woman feels cold in a room of degF
and another feels hot Age alters hearing seeing memory and
may jangle judgments Te upshot is that we cannot find a place
to stand to see the world as it is We are simply ill-equipped to
do so Objective truth what is independent of our perceptions
endlessly and mercilessly eludes us
We will return to skepticism when discussing Descartes and
Pascal but Protagoras was not a skeptic He did not withhold
judgments about facts in themselves because we do not have the
ability to know them While recognizing that the skeptics had
dethroned our intellectual confidence in capturing objective re-
ality his point of departure was this we do know our own view-
points judgments and beliefs Tat is we measure things theydo not measure themselves So I take most of Francis Baconrsquos
paintings to be ugly and thus unattractive I am repulsed Tis is
the end of the story or my story Tis is my measurement You
on the contrary may find delight in Baconrsquos tortured figures and
color schemes Tat is your measurement and the end of your
story
Now reconsider the skeptical point made earlier One person
can deem the room cold and another hot Te skeptic might say
we cannot know then what the room is given the variability in
perception But Protagoras claims that the room is hot for person

A and not hot for person B Tere is no contradiction since we
are considering individual perceptions Tere are two measure-
ments each of which is valid Tus Bacon is barbaric to me and
beautiful to youmdashand that is the level best we can do Or perhaps
I will come to adore Baconrsquos paintings and heap scorn on my
former judgment If so then that is my measurement
Tis is rather attractive at first blush After all there is no
dispute in matters of taste or to be more snobby De gustibus
non est disputandum Te avant-garde saxophone playing ofPeter Broumltzmann can send me into the upper reaches of aes-
thetic delight while sending others scurrying from the room
while covering their ears But Protagoras took this insight far
beyond artistic judgments Notice the reference range (or extent)
of Protagorasrsquos statement ldquoMan is the measure of all thingsrdquomdash
matters of taste as well as matters of fact matters of principle
and matters of matter Nothing is excluded
Let us follow this out As we think it through the old Greek
will sound much like modern man If Protagoras is right then
there is no disputing matters of morality either Man is the
measure of what is right and what is wrong what is virtuous and
what is vicious what should be loved and what should be hatedmdash
just as Hamlet claimed oday this thinking is usually put in thelanguage of choice instead of measurement but the idea is the
same If you chose to do X that choice is the end of the matter
Or to suit Protagoras if you measure X as worth doing then it
is worth doing Tis is true whether X refers to sailing stealing
or stampeding cattle in the direction of a Cub Scout outing
But we might say ldquoWho is to judgerdquo Who of us can stand
above him- or herself and others and become objective Yes we
recoil from some ideasmdashsuch as torturing the innocent merely
for pleasure or female genital mutilation But what does that tell
us about reality if there really is such a thing as reality Te claim

Besides being a serial killer ed Bundy was a philosophical

Moral Philosophy Bundy said
I learned that all moral judgments are ldquovalue judgmentsrdquo
that all value judgments are subjective and that none can
be proved to be either ldquorightrdquo or ldquowrongrdquo I even read some-where that the Chief Justice of the United States had written
that the American Constitution expressed nothing more
than collective value judgments Believe it or not I figured
out for myselfmdashwhat apparently the Chief Justice couldnrsquot
figure out for himselfmdashthat if the rationality of one value
judgment was zero multiplying it by millions would not
make it one whit more rational Nor is there any ldquoreasonrdquo
to obey the law for anyone like myself who has the
boldness and daring ldquothe strength of characterrdquo to throw
off its shackles
I discovered that to become truly free truly unfettered
I had to become truly uninhibited And I quickly discovered
that the greatest obstacle to my freedom the greatest blockand limitation to it consists in the insupportable ldquovalue

When teaching ethics to undergraduates at a secular school I
often hand out this Bundy quotation but without identifying the
speaker I then ask them to write a paragraph on whether they
agree with its basic idea Most students approve of the unknown

philosophy of one of the most infamous serial killers in American
historymdashthe philosophy that allowed and even impelled hisegregious crimes Next I ask them to reconsider their judg-

dents show dismay and surprise that they were in agreement

agree with Protagoras at least implicitly there is no objective

us and nothing beneath us It is all merely neutral and we make

existentially Tey often capture some truth and so seduce us
on this basis But a statement cannot be true unless it accords
with the way the world in fact is and the way we in fact are Pro-
tagoras does capture some truths about perspective For ex-
ample my tastes in food determine how I measure the goodness
of the food I am the measure of that at least It matters nothing
whether a connoisseur thinks me an ignoramus I can only
measure it by what I experience at the moment In that way I am
the measure but am I the expert Am I the knowerTere is a strange implication for Protagorasrsquos view In the
Teaetetus Protagoras even states that error is impossible5 Al-
though he was a teacher he cannot by his own lights teach
anyone o this Socrates inquires
If whatever the individual judges by means of perception is
true for him if no man can assess anotherrsquos experiencebetter than he or can claim authority to examine another
manrsquos judgment and see if it be right or wrong if as we
have repeatedly said only the individual himself can judge
of his own world and what he judges is always true and
correct how could it ever be my friend that Protagoras
was a wise man so wise as to think himself fit to be the
teacher of other men and worth large fees while we in
comparison with him the ignorant ones needed to go and
sit at his feetmdashwe who are ourselves each the measure of
his own wisdom6

human languages For example the general concept of cat may
be written in Chinese or in English Since each language uses
different symbols for writing its graphic inscription for cat will
differ Tis is true for voicing the word cat as well Trough a
long messy process not instigated by any central planning each
culture selects its own conventions of communication Are not
these two systems of writing measuring reality in very different
ways In point of fact they are not
Both kinds of writing systems (as well as other means ofcommunication) make claims about a reality that are outside
of the systems themselves and outside of the individuals who
use the pictographic or ideographic methods We tacitly saw
this earlier But in both cases a cat is invoked there is a single
referent Te differences in linguistic custom are not differ-
ences in content A cat is a cat in whatever language and it will
not bark however it may be measured Moreover while it may
be vexing in places one can translate a book from English to
Chinese Not everything is lost in translation in fact more is
found than is lost ranslators need have no fear of losing their
livelihood
Staying on matters of taste for a moment (and not morality
for now) are all people equally skilled in measurement Tepoet and literary critic S Eliot advocated the cultivation of
ldquoeducated tasterdquo Consider your preferences in music and
reading when you were quite young Tey are likely not the
same as when you became an adult You may still enjoy and
laugh at nursery rhymes but your tastes have expanded Yes
you still love Winnie the Pooh (and I mean the original Pooh
not the Walt Disney version) but you understand and appre-
ciate it more deeply now If so (and substitute your own ex-
amples here if needed) your tastes have at least changed and
have likely improved with age Your earlier judgments were

likely age appropriate but they were limited and (not unex-
pectedly) childish Te apostle Paul notes this in a well-known
turn of phrase ldquoWhen I was a child I talked like a child I
thought like a child I reasoned like a child When I became a
man I put the ways of childhood behind merdquo ( Corinthians
see also Hebrews -)
Furthermore the very notion of improvement or progress
(not merely some change in quality) requires and assumes an
objective standard by which to measure improvement (or de-cline) If a baseball batter hits in and in he
has improved based on the best possible average of Tere
is a measurement and it is not the perception of the batter that
determines this measurement Tis is the case in the arts as well
Few knowledgeable about jazz would dispute that John Col-
tranersquos saxophone work improved during his tenure with pianist
Telonious Monkrsquos quartet or that it developed further in Col-
trane own ldquoclassic quartetrdquo (ndash)7 Here the assessment is
not quantitative or statistical but qualitative One might object
that this is a purely subjective judgment (such as whether one
feels hot or not) which is relative to the person hearing Who is
to judge Te answer is straightforward the one whose expe-
rience knowledge and wisdom merit approval Although manydrink wine there are few expert wine tasters A student of mine
is so adept at this art that he can tell what part of the country a
wine came from Not having developed this advanced degree of
skill this is foreign to me However I had no inclination to say
that my judgment on wine is as accurate as Markrsquos Along these
lines I was once embarrassed when one of my students told me
that the wine I was enjoying was ldquothe Kenny G of winesrdquo Tis as
jazz aficionados know was not a compliment about the wine or
about my taste for wine
Artistic judgments involve much more than my quick treatment

beauty is not only in the eye of the beholder If not we are haunted

But Herodotus may yet rescue Protagoras In his History the
ancient historian notes that Darius a king of ancient Persia (who
was a kind of premodern anthropologist because of his study of
cultural differences) called together some Greeks and askedthem what it would take to cannibalize their dead fathers Te
Greeks needed no time to ponder the proposition since nothing
would move them to such odious paternal desecration Teir
practice was cremation this alone would honor their dead Ten
Darius summoned several Callatians (from India) to join the
Greeks and asked them what would make them cremate their
deceased fathers Te Callatians were as horrified as the Greeks
had been and told Darius to not discuss such atrocities
Had Protagoras heard this he would likely applaud having
found more evidence for his outlook But not all applause is
earned While the Greeks and Callatians observed fundamen-
tally different funeral rites both cultures honored the dead Tat
is only particular practicesmdashnot just any old or new thingmdashwere esteemed right and good in the treatment of corpses and
these practices were not norms for the treatment of the living
In other words death was set apart as uniquely meaningful and
thus required that the living treat the dead with ritual respect
Tus Greeks and Callatians agreed on a deep principle of hon-
oring the dead Tey disagreed on the rule that stems from that
principle In no sense then does the example of cultural rela-
tivity disprove moral agreement across cultures since there was
deep agreement between the cultures C S Lewis makes just
this point in Mere Christianity

Protagoras
I know that some people say the idea of a Law of Nature or
decent behaviour known to all men is unsound because
different civilisations and different ages have had quite dif-
ferent moralities
But this is not true Tere have been differences between
their moralities but these have never amounted to any-
thing like a total difference If anyone will take the trouble
to compare the moral teaching of say the ancient Egyp-
tians Babylonians Hindus Chinese Greeks and Romanswhat will really strike him will be how very like they are to
each other and to our own9
Te case against Protagoras comes down to this If we want to
learn anything if we want to improve as human beings if we
want to condemn the ed Bundys of the world if we want any
kind of educated taste if we desire to understand and honorhumanity then we must reject the ldquoman is the measurerdquo theory
Each person is indeed the measurer of some things Some of
them the individual gets right some of them the individual gets
wrong And in this difference lies all the difference in the world
and even outside of it

Philosophy in Only Seven Sentences
Our last sentence is not as well known as the previous ones
but it opens a door of inquiry for us
Te greatest hazard of all losing onersquos self can occur very
quietly in the world as if it were nothing at all
It was penned by an idiosyncratic and famously melancholy
Dane named Soslashren Kierkegaard a philosopher intensely inter-
ested in the self in relation to ultimate reality Tis should sound
familiar since all philosophers have expressed this interest inone way or another But Kierkegaardrsquos way was in a sense as
much psychological as philosophical He intrepidly limned the
inner workings of the self of consciousness in philosophical
categories Like Pascal Kierkegaard wanted to strip away
through existential analysis the layers and dynamics of the self
that keep reality at bay Unlike Pascal and the other philosophers
he was more interested in the analysis of the self than presentingit with arguments for an abstract objective reality Tis may
sound a bit unphilosophical but it is not But that takes time to
tease out properly as I hope you will see
Our seven sentences may be viewed as several doors into
worlds previously unknown Or they may be our irritants to
prod us to move away from facile factoidsmdashldquoDo your own thingrdquoldquoFollow your blissrdquo ldquoKeep Calm and Carry Onrdquomdashto more so-
bering reflections9 Perhaps the sentences are bridges to other
lands of thought Tese philosophical sentences do not sum the
thought of any of the philosophers for these thinkers are far too
deep for that Nor do the seven sentences aim to summarize the
history of philosophy Tat would be a pompous and laughable
claim Some things cannot be put into a nutshell including thenutshell itself But I claim that philosophical activity can be
sparked by just seven sterling sentencesmdashand who knows where
it might lead

PROTAGORAS
Man is the measure of all things
P
Greeks could do philosophy Te basic questions of exis-
tence have never been far from the human mind but the
ancient Greeks excelled at this and their musingsmdashsome frag-
mentary or secondhandmdashhave been preserved in written texts
However much philosophy occurred in exclusively oral cultures
the Greeks valued writing in addition to oral memory and tra-
dition Socrates you remember wrote nothing but generated a vast literature though his dialogues A lesser-known figure who
came after him did write a few things and his famous adage is
worth considering
Protagoras (fifth century BC) is not to be confused with
like-sounding ancient Greek thinkers named Pythagoras or
Parmenides who along with others were pre-Socratic thinkers
(Tis shows the significance of Socrates since philosophy isdated with respect to his life) Tese thinkers are worth inter-
rogating as well and I studied them with profit in a year-long
course in ancient philosophy forty years ago Protagoras

stands out to us though because of his adage about absolute
assessment
Man is the measure of all things of the things which are
that they are and of things which are not that they are not1
His claim is not simply that people measure thingsmdashsuch as
character chariots boats and fishmdashbut that each human is the
measure Each person is the assessment or judgment What
could this mean No person is a slide ruler or scale or Geigercounter although we avail ourselves of such things
W I M
We tend to think that people use a standard of measurement
outside of themselves Even inadequate and one-dimensional
measures such as onersquos IQ score are not determined by how we
feel about themmdashand Mensa is very picky about thisOn the other hand Protagoras has Shakespearersquos Hamlet on
his side at least concerning morality ldquoFor there is nothing either
good or bad but thinking makes it sordquo2 Tat is morals do not
have objective standing rather they are judged differently by
different people Tis quote is from a discussion about Denmark
which Hamlet unlike his interlocutor Rosencrantz said was ldquoaprisonrdquo If Hamlet is right then both Hamlet and Rosencrantz
are right about Denmark
What then was Protagorasrsquos point (Wersquoll put serious Shake-
spearian interpretation aside) o find out we need to take a step
back into the Greek philosophical scene and not rush to
judgmentmdashor rush to endorsement either Protagoras would ap-
prove of this deliberationProtagoras was considered the chief of the Sophists intellec-
tuals who were paid to defend the views of their sponsors Tey
were accomplished orators as well as thinkers Originally the

term sophist meant something like our ldquoprofessorrdquo but later a
Sophist was deemed a hired gun a philosopher for hire and one
having no principles of his own Teir arguments supposedly
were merely the instruments of the will of their bosses One may
argue over the virtues of the Sophists but it is certainly not true
that being paid for philosophizing necessarily disqualifies the
employeersquos arguments On the other hand if we think of a
Sophist as something like a political speech writer or the like
our judgment will change Whatever the intellectual rectitudeof Protagoras he was a perpetual lecturer who articulated and
debated ideas in the marketplace a marketplace of ideas that yet
exists We may join in the discussion

Protagoras was one of a spirited group of fastidious thinkers
who tired or at least grew skeptical of Greek mythology with
its pantheon of gods Yes the stories of the gods were often riv-
eting and worth repeating A recent volume by Luc Ferry is
called Te Wisdom of the Myths How Greek Mythology Can
Change Your Life3 Tere was always a moral to the story Her-
cules the last son of Zeus was a dashing and dramatic character
who started as a mighty mortal and became a god upon deathAlthough a bit impetuous and lacking in sobriety he plays well
as a hero Zeus himself is the apotheosis of power but acts
largely without moral authority Even the might of Zeus does not
support the idea that ldquomight makes rightrdquo since might may make
for divine mischief My point is not to survey or psychoanalyze
the denizens of Greek mythology but to make a general point
Mythologies may inspire and guide to some extent our relation
to the hard facts of family life death and sexuality (and some of
the gods tended to be naughty in this way)
Nevertheless the problem with Greek mythology (or any

mythology Eastern or Western) is simply that it is mythology it
is neither history nor clearly articulated philosophy In too many
ways the gods despite their thespian reacutesumeacutes and magical
powers were not much more than semi- glorified mortals Tis
was the objection of a growing group of Greeks who were mere
mortalsmdashmortals with meaning metaphysics and morality on
their minds And what might the mind do when free to explore
life and its questions apart from the venerable stories of Greek
fascination It might philosophize and so it didProtagoras and his cohorts quested for explanations of a more
abstract but also compelling sort than the old tales could afford
Tey sought principles to explain facts in a universal and logi-
cally coherent manner o be a little unfair to the mythologies
consider the tooth fairy She adds some magical benevolence to
the loss and placement of a baby tooth for children but the fairy
story adds nothing about the nature of benevolence the signifi-
cance of teeth or the significance of the humans who grow and
lose these teeth whether through development (teething) or
decay (the toothless)
Tus to give one example Tales of Miletus tried to find a
cosmic commonality to all things He divined it as water Yes
water which was more than rain oceans lakes and puddles Itwas everywhere so perhaps it was the root and branch of every-
thing Water or moisture in general lives in the clouds in plants
in animals (aquatic land or amphibious) and in thirsty mortals
It condenses and evaporates but never leaves the planet Con-
sidering the presence and power of water Tales extrapolated
that water was more than one more thing on earth however
necessary for life It was rather the unifying principle for exis-
tence Whatever we think of Tales his thinking is not absurd
and it indicates a thirst for philosophical explanation as opposed
to mythological meanderings At least he was trying

But Herodotus may yet rescue Protagoras In his History the
ancient historian notes that Darius a king of ancient Persia (who
was a kind of premodern anthropologist because of his study of
cultural differences) called together some Greeks and askedthem what it would take to cannibalize their dead fathers Te
Greeks needed no time to ponder the proposition since nothing
would move them to such odious paternal desecration Teir
practice was cremation this alone would honor their dead Ten
Darius summoned several Callatians (from India) to join the
Greeks and asked them what would make them cremate their
deceased fathers Te Callatians were as horrified as the Greeks
had been and told Darius to not discuss such atrocities
Had Protagoras heard this he would likely applaud having
found more evidence for his outlook But not all applause is
earned While the Greeks and Callatians observed fundamen-
tally different funeral rites both cultures honored the dead Tat
is only particular practicesmdashnot just any old or new thingmdashwere esteemed right and good in the treatment of corpses and
these practices were not norms for the treatment of the living
In other words death was set apart as uniquely meaningful and
thus required that the living treat the dead with ritual respect
Tus Greeks and Callatians agreed on a deep principle of hon-
oring the dead Tey disagreed on the rule that stems from that
principle In no sense then does the example of cultural rela-
tivity disprove moral agreement across cultures since there was
deep agreement between the cultures C S Lewis makes just
this point in Mere Christianity

Protagoras
I know that some people say the idea of a Law of Nature or
decent behaviour known to all men is unsound because
different civilisations and different ages have had quite dif-
ferent moralities
But this is not true Tere have been differences between
their moralities but these have never amounted to any-
thing like a total difference If anyone will take the trouble
to compare the moral teaching of say the ancient Egyp-
tians Babylonians Hindus Chinese Greeks and Romanswhat will really strike him will be how very like they are to
each other and to our own9
Te case against Protagoras comes down to this If we want to
learn anything if we want to improve as human beings if we
want to condemn the ed Bundys of the world if we want any
kind of educated taste if we desire to understand and honorhumanity then we must reject the ldquoman is the measurerdquo theory
Each person is indeed the measurer of some things Some of
them the individual gets right some of them the individual gets
wrong And in this difference lies all the difference in the world
and even outside of it

PROTAGORAS
Man is the measure of all things
P
Greeks could do philosophy Te basic questions of exis-
tence have never been far from the human mind but the
ancient Greeks excelled at this and their musingsmdashsome frag-
mentary or secondhandmdashhave been preserved in written texts
However much philosophy occurred in exclusively oral cultures
the Greeks valued writing in addition to oral memory and tra-
dition Socrates you remember wrote nothing but generated a vast literature though his dialogues A lesser-known figure who
came after him did write a few things and his famous adage is
worth considering
Protagoras (fifth century BC) is not to be confused with
like-sounding ancient Greek thinkers named Pythagoras or
Parmenides who along with others were pre-Socratic thinkers
(Tis shows the significance of Socrates since philosophy isdated with respect to his life) Tese thinkers are worth inter-
rogating as well and I studied them with profit in a year-long
course in ancient philosophy forty years ago Protagoras

stands out to us though because of his adage about absolute
assessment
Man is the measure of all things of the things which are
that they are and of things which are not that they are not1
His claim is not simply that people measure thingsmdashsuch as
character chariots boats and fishmdashbut that each human is the
measure Each person is the assessment or judgment What
could this mean No person is a slide ruler or scale or Geigercounter although we avail ourselves of such things
W I M
We tend to think that people use a standard of measurement
outside of themselves Even inadequate and one-dimensional
measures such as onersquos IQ score are not determined by how we
feel about themmdashand Mensa is very picky about thisOn the other hand Protagoras has Shakespearersquos Hamlet on
his side at least concerning morality ldquoFor there is nothing either
good or bad but thinking makes it sordquo2 Tat is morals do not
have objective standing rather they are judged differently by
different people Tis quote is from a discussion about Denmark
which Hamlet unlike his interlocutor Rosencrantz said was ldquoaprisonrdquo If Hamlet is right then both Hamlet and Rosencrantz
are right about Denmark
What then was Protagorasrsquos point (Wersquoll put serious Shake-
spearian interpretation aside) o find out we need to take a step
back into the Greek philosophical scene and not rush to
judgmentmdashor rush to endorsement either Protagoras would ap-
prove of this deliberationProtagoras was considered the chief of the Sophists intellec-
tuals who were paid to defend the views of their sponsors Tey
were accomplished orators as well as thinkers Originally the

term sophist meant something like our ldquoprofessorrdquo but later a
Sophist was deemed a hired gun a philosopher for hire and one
having no principles of his own Teir arguments supposedly
were merely the instruments of the will of their bosses One may
argue over the virtues of the Sophists but it is certainly not true
that being paid for philosophizing necessarily disqualifies the
employeersquos arguments On the other hand if we think of a
Sophist as something like a political speech writer or the like
our judgment will change Whatever the intellectual rectitudeof Protagoras he was a perpetual lecturer who articulated and
debated ideas in the marketplace a marketplace of ideas that yet
exists We may join in the discussion

Protagoras was one of a spirited group of fastidious thinkers
who tired or at least grew skeptical of Greek mythology with
its pantheon of gods Yes the stories of the gods were often riv-
eting and worth repeating A recent volume by Luc Ferry is
called Te Wisdom of the Myths How Greek Mythology Can
Change Your Life3 Tere was always a moral to the story Her-
cules the last son of Zeus was a dashing and dramatic character
who started as a mighty mortal and became a god upon deathAlthough a bit impetuous and lacking in sobriety he plays well
as a hero Zeus himself is the apotheosis of power but acts
largely without moral authority Even the might of Zeus does not
support the idea that ldquomight makes rightrdquo since might may make
for divine mischief My point is not to survey or psychoanalyze
the denizens of Greek mythology but to make a general point
Mythologies may inspire and guide to some extent our relation
to the hard facts of family life death and sexuality (and some of
the gods tended to be naughty in this way)
Nevertheless the problem with Greek mythology (or any

mythology Eastern or Western) is simply that it is mythology it
is neither history nor clearly articulated philosophy In too many
ways the gods despite their thespian reacutesumeacutes and magical
powers were not much more than semi- glorified mortals Tis
was the objection of a growing group of Greeks who were mere
mortalsmdashmortals with meaning metaphysics and morality on
their minds And what might the mind do when free to explore
life and its questions apart from the venerable stories of Greek
fascination It might philosophize and so it didProtagoras and his cohorts quested for explanations of a more
abstract but also compelling sort than the old tales could afford
Tey sought principles to explain facts in a universal and logi-
cally coherent manner o be a little unfair to the mythologies
consider the tooth fairy She adds some magical benevolence to
the loss and placement of a baby tooth for children but the fairy
story adds nothing about the nature of benevolence the signifi-
cance of teeth or the significance of the humans who grow and
lose these teeth whether through development (teething) or
decay (the toothless)
Tus to give one example Tales of Miletus tried to find a
cosmic commonality to all things He divined it as water Yes
water which was more than rain oceans lakes and puddles Itwas everywhere so perhaps it was the root and branch of every-
thing Water or moisture in general lives in the clouds in plants
in animals (aquatic land or amphibious) and in thirsty mortals
It condenses and evaporates but never leaves the planet Con-
sidering the presence and power of water Tales extrapolated
that water was more than one more thing on earth however
necessary for life It was rather the unifying principle for exis-
tence Whatever we think of Tales his thinking is not absurd
and it indicates a thirst for philosophical explanation as opposed
to mythological meanderings At least he was trying

Protagoras
D W D R
But it is Protagoras who calls for our attention Instead of ar-guing for something at the heart of everything (water for Tales)
a principle found in nature Protagoras moved back from nature
to the self After all skeptics had questioned mere mortalsrsquo
ability to know with any confidence what is out there inde-
pendent of themselves Te jaundiced eye sees things differently
from the nonjaundiced eye Children perceive entities invisible
to adults Adults sometimes hallucinatemdashbut perhaps they areseeing what most miss One woman feels cold in a room of degF
and another feels hot Age alters hearing seeing memory and
may jangle judgments Te upshot is that we cannot find a place
to stand to see the world as it is We are simply ill-equipped to
do so Objective truth what is independent of our perceptions
endlessly and mercilessly eludes us
We will return to skepticism when discussing Descartes and
Pascal but Protagoras was not a skeptic He did not withhold
judgments about facts in themselves because we do not have the
ability to know them While recognizing that the skeptics had
dethroned our intellectual confidence in capturing objective re-
ality his point of departure was this we do know our own view-
points judgments and beliefs Tat is we measure things theydo not measure themselves So I take most of Francis Baconrsquos
paintings to be ugly and thus unattractive I am repulsed Tis is
the end of the story or my story Tis is my measurement You
on the contrary may find delight in Baconrsquos tortured figures and
color schemes Tat is your measurement and the end of your
story
Now reconsider the skeptical point made earlier One person
can deem the room cold and another hot Te skeptic might say
we cannot know then what the room is given the variability in
perception But Protagoras claims that the room is hot for person

A and not hot for person B Tere is no contradiction since we
are considering individual perceptions Tere are two measure-
ments each of which is valid Tus Bacon is barbaric to me and
beautiful to youmdashand that is the level best we can do Or perhaps
I will come to adore Baconrsquos paintings and heap scorn on my
former judgment If so then that is my measurement
Tis is rather attractive at first blush After all there is no
dispute in matters of taste or to be more snobby De gustibus
non est disputandum Te avant-garde saxophone playing ofPeter Broumltzmann can send me into the upper reaches of aes-
thetic delight while sending others scurrying from the room
while covering their ears But Protagoras took this insight far
beyond artistic judgments Notice the reference range (or extent)
of Protagorasrsquos statement ldquoMan is the measure of all thingsrdquomdash
matters of taste as well as matters of fact matters of principle
and matters of matter Nothing is excluded
Let us follow this out As we think it through the old Greek
will sound much like modern man If Protagoras is right then
there is no disputing matters of morality either Man is the
measure of what is right and what is wrong what is virtuous and
what is vicious what should be loved and what should be hatedmdash
just as Hamlet claimed oday this thinking is usually put in thelanguage of choice instead of measurement but the idea is the
same If you chose to do X that choice is the end of the matter
Or to suit Protagoras if you measure X as worth doing then it
is worth doing Tis is true whether X refers to sailing stealing
or stampeding cattle in the direction of a Cub Scout outing
But we might say ldquoWho is to judgerdquo Who of us can stand
above him- or herself and others and become objective Yes we
recoil from some ideasmdashsuch as torturing the innocent merely
for pleasure or female genital mutilation But what does that tell
us about reality if there really is such a thing as reality Te claim

Protagoras
that ldquoman is the measure of all thingsrdquo is an all-encompassing
judgment itself Te answer to ldquoWho is to judgerdquo is that we are
the measure of all things Tat is there is nothing outside of
human judgment by which it might be judged But why would
Protagoras (or anyone else) consider that to be reality itself

Besides being a serial killer ed Bundy was a philosophical
thinker of the Protagorean type Remarkably his philosophy wascaught on tape before he raped and killed a young woman She
was one of dozens of his prey As reported in Louis Pojmanrsquos text
Moral Philosophy Bundy said
I learned that all moral judgments are ldquovalue judgmentsrdquo
that all value judgments are subjective and that none can
be proved to be either ldquorightrdquo or ldquowrongrdquo I even read some-where that the Chief Justice of the United States had written
that the American Constitution expressed nothing more
than collective value judgments Believe it or not I figured
out for myselfmdashwhat apparently the Chief Justice couldnrsquot
figure out for himselfmdashthat if the rationality of one value
judgment was zero multiplying it by millions would not
make it one whit more rational Nor is there any ldquoreasonrdquo
to obey the law for anyone like myself who has the
boldness and daring ldquothe strength of characterrdquo to throw
off its shackles
I discovered that to become truly free truly unfettered
I had to become truly uninhibited And I quickly discovered
that the greatest obstacle to my freedom the greatest blockand limitation to it consists in the insupportable ldquovalue

cultural differences) called together some Greeks and askedthem what it would take to cannibalize their dead fathers Te
Greeks needed no time to ponder the proposition since nothing
would move them to such odious paternal desecration Teir
practice was cremation this alone would honor their dead Ten
Darius summoned several Callatians (from India) to join the
Greeks and asked them what would make them cremate their
deceased fathers Te Callatians were as horrified as the Greeks
had been and told Darius to not discuss such atrocities
Had Protagoras heard this he would likely applaud having
found more evidence for his outlook But not all applause is
earned While the Greeks and Callatians observed fundamen-
tally different funeral rites both cultures honored the dead Tat
is only particular practicesmdashnot just any old or new thingmdashwere esteemed right and good in the treatment of corpses and
these practices were not norms for the treatment of the living
In other words death was set apart as uniquely meaningful and
thus required that the living treat the dead with ritual respect
Tus Greeks and Callatians agreed on a deep principle of hon-
oring the dead Tey disagreed on the rule that stems from that
principle In no sense then does the example of cultural rela-
tivity disprove moral agreement across cultures since there was
deep agreement between the cultures C S Lewis makes just

each other and to our own9
Te case against Protagoras comes down to this If we want to
learn anything if we want to improve as human beings if we
want to condemn the ed Bundys of the world if we want any
kind of educated taste if we desire to understand and honorhumanity then we must reject the ldquoman is the measurerdquo theory

stands out to us though because of his adage about absolute
assessment
Man is the measure of all things of the things which are
that they are and of things which are not that they are not1
His claim is not simply that people measure thingsmdashsuch as
character chariots boats and fishmdashbut that each human is the
measure Each person is the assessment or judgment What
could this mean No person is a slide ruler or scale or Geigercounter although we avail ourselves of such things

We tend to think that people use a standard of measurement
outside of themselves Even inadequate and one-dimensional
measures such as onersquos IQ score are not determined by how we
feel about themmdashand Mensa is very picky about thisOn the other hand Protagoras has Shakespearersquos Hamlet on
his side at least concerning morality ldquoFor there is nothing either
good or bad but thinking makes it sordquo2 Tat is morals do not
have objective standing rather they are judged differently by
different people Tis quote is from a discussion about Denmark
which Hamlet unlike his interlocutor Rosencrantz said was ldquoaprisonrdquo If Hamlet is right then both Hamlet and Rosencrantz
are right about Denmark
What then was Protagorasrsquos point (Wersquoll put serious Shake-
spearian interpretation aside) o find out we need to take a step
back into the Greek philosophical scene and not rush to
judgmentmdashor rush to endorsement either Protagoras would ap-
prove of this deliberationProtagoras was considered the chief of the Sophists intellec-

largely without moral authority Even the might of Zeus does not
support the idea that ldquomight makes rightrdquo since might may make

ways the gods despite their thespian reacutesumeacutes and magical
powers were not much more than semi- glorified mortals Tis
was the objection of a growing group of Greeks who were mere
mortalsmdashmortals with meaning metaphysics and morality on
their minds And what might the mind do when free to explore
life and its questions apart from the venerable stories of Greek
fascination It might philosophize and so it didProtagoras and his cohorts quested for explanations of a more
abstract but also compelling sort than the old tales could afford
Tey sought principles to explain facts in a universal and logi-
cally coherent manner o be a little unfair to the mythologies
consider the tooth fairy She adds some magical benevolence to
the loss and placement of a baby tooth for children but the fairy
story adds nothing about the nature of benevolence the signifi-
cance of teeth or the significance of the humans who grow and
lose these teeth whether through development (teething) or
decay (the toothless)
Tus to give one example Tales of Miletus tried to find a
cosmic commonality to all things He divined it as water Yes
water which was more than rain oceans lakes and puddles Itwas everywhere so perhaps it was the root and branch of every-
thing Water or moisture in general lives in the clouds in plants
in animals (aquatic land or amphibious) and in thirsty mortals
It condenses and evaporates but never leaves the planet Con-
sidering the presence and power of water Tales extrapolated
that water was more than one more thing on earth however
necessary for life It was rather the unifying principle for exis-

But it is Protagoras who calls for our attention Instead of ar-guing for something at the heart of everything (water for Tales)
a principle found in nature Protagoras moved back from nature
to the self After all skeptics had questioned mere mortalsrsquo
ability to know with any confidence what is out there inde-
pendent of themselves Te jaundiced eye sees things differently

may jangle judgments Te upshot is that we cannot find a place
to stand to see the world as it is We are simply ill-equipped to
do so Objective truth what is independent of our perceptions
endlessly and mercilessly eludes us
We will return to skepticism when discussing Descartes and
Pascal but Protagoras was not a skeptic He did not withhold
judgments about facts in themselves because we do not have the
ability to know them While recognizing that the skeptics had
dethroned our intellectual confidence in capturing objective re-

are considering individual perceptions Tere are two measure-

I will come to adore Baconrsquos paintings and heap scorn on my
former judgment If so then that is my measurement
Tis is rather attractive at first blush After all there is no
dispute in matters of taste or to be more snobby De gustibus
non est disputandum Te avant-garde saxophone playing ofPeter Broumltzmann can send me into the upper reaches of aes-
thetic delight while sending others scurrying from the room
while covering their ears But Protagoras took this insight far
beyond artistic judgments Notice the reference range (or extent)
of Protagorasrsquos statement ldquoMan is the measure of all thingsrdquomdash
matters of taste as well as matters of fact matters of principle
and matters of matter Nothing is excluded
Let us follow this out As we think it through the old Greek
will sound much like modern man If Protagoras is right then
there is no disputing matters of morality either Man is the
measure of what is right and what is wrong what is virtuous and
what is vicious what should be loved and what should be hatedmdash
just as Hamlet claimed oday this thinking is usually put in thelanguage of choice instead of measurement but the idea is the
same If you chose to do X that choice is the end of the matter
Or to suit Protagoras if you measure X as worth doing then it
is worth doing Tis is true whether X refers to sailing stealing
or stampeding cattle in the direction of a Cub Scout outing
But we might say ldquoWho is to judgerdquo Who of us can stand
above him- or herself and others and become objective Yes we
recoil from some ideasmdashsuch as torturing the innocent merely
for pleasure or female genital mutilation But what does that tell
us about reality if there really is such a thing as reality Te claim

that ldquoman is the measure of all thingsrdquo is an all-encompassing

Besides being a serial killer ed Bundy was a philosophical

was one of dozens of his prey As reported in Louis Pojmanrsquos text
Moral Philosophy Bundy said
I learned that all moral judgments are ldquovalue judgmentsrdquo
that all value judgments are subjective and that none can
be proved to be either ldquorightrdquo or ldquowrongrdquo I even read some-where that the Chief Justice of the United States had written
that the American Constitution expressed nothing more
than collective value judgments Believe it or not I figured
out for myselfmdashwhat apparently the Chief Justice couldnrsquot
figure out for himselfmdashthat if the rationality of one value
judgment was zero multiplying it by millions would not
make it one whit more rational Nor is there any ldquoreasonrdquo
to obey the law for anyone like myself who has the
boldness and daring ldquothe strength of characterrdquo to throw
off its shackles
I discovered that to become truly free truly unfettered
I had to become truly uninhibited And I quickly discovered
that the greatest obstacle to my freedom the greatest blockand limitation to it consists in the insupportable ldquovalue

Why should I be willing to sacrifice my pleasure more for

When teaching ethics to undergraduates at a secular school I
often hand out this Bundy quotation but without identifying the

philosophy of one of the most infamous serial killers in American
historymdashthe philosophy that allowed and even impelled hisegregious crimes Next I ask them to reconsider their judg-
ments Te results are usually mixed but the majority of stu-
dents show dismay and surprise that they were in agreement
with a view that justified serial rape and murder

a serial killer named Dexter o top that off there is even a book
called Dexter and Philosophy Mind over Spatter Can such atroc-

us and nothing beneath us It is all merely neutral and we make

existentially Tey often capture some truth and so seduce us
on this basis But a statement cannot be true unless it accords
with the way the world in fact is and the way we in fact are Pro-
tagoras does capture some truths about perspective For ex-
ample my tastes in food determine how I measure the goodness
of the food I am the measure of that at least It matters nothing
whether a connoisseur thinks me an ignoramus I can only
measure it by what I experience at the moment In that way I am
the measure but am I the expert Am I the knowerTere is a strange implication for Protagorasrsquos view In the
Teaetetus Protagoras even states that error is impossible5 Al-
though he was a teacher he cannot by his own lights teach
anyone o this Socrates inquires
If whatever the individual judges by means of perception is
true for him if no man can assess anotherrsquos experiencebetter than he or can claim authority to examine another
manrsquos judgment and see if it be right or wrong if as we
have repeatedly said only the individual himself can judge
of his own world and what he judges is always true and
correct how could it ever be my friend that Protagoras
was a wise man so wise as to think himself fit to be the
teacher of other men and worth large fees while we in
comparison with him the ignorant ones needed to go and
sit at his feetmdashwe who are ourselves each the measure of
his own wisdom6

human languages For example the general concept of cat may
be written in Chinese or in English Since each language uses
different symbols for writing its graphic inscription for cat will
differ Tis is true for voicing the word cat as well Trough a
long messy process not instigated by any central planning each
culture selects its own conventions of communication Are not
these two systems of writing measuring reality in very different
ways In point of fact they are not
Both kinds of writing systems (as well as other means ofcommunication) make claims about a reality that are outside
of the systems themselves and outside of the individuals who
use the pictographic or ideographic methods We tacitly saw
this earlier But in both cases a cat is invoked there is a single
referent Te differences in linguistic custom are not differ-
ences in content A cat is a cat in whatever language and it will
not bark however it may be measured Moreover while it may
be vexing in places one can translate a book from English to
Chinese Not everything is lost in translation in fact more is
found than is lost ranslators need have no fear of losing their
livelihood
Staying on matters of taste for a moment (and not morality
for now) are all people equally skilled in measurement Tepoet and literary critic S Eliot advocated the cultivation of

reading when you were quite young Tey are likely not the
same as when you became an adult You may still enjoy and
laugh at nursery rhymes but your tastes have expanded Yes
you still love Winnie the Pooh (and I mean the original Pooh
not the Walt Disney version) but you understand and appre-
ciate it more deeply now If so (and substitute your own ex-
amples here if needed) your tastes have at least changed and
have likely improved with age Your earlier judgments were

pectedly) childish Te apostle Paul notes this in a well-known
turn of phrase ldquoWhen I was a child I talked like a child I
thought like a child I reasoned like a child When I became a
man I put the ways of childhood behind merdquo ( Corinthians

Furthermore the very notion of improvement or progress
(not merely some change in quality) requires and assumes an
objective standard by which to measure improvement (or de-cline) If a baseball batter hits in and in he
has improved based on the best possible average of Tere
is a measurement and it is not the perception of the batter that
determines this measurement Tis is the case in the arts as well
Few knowledgeable about jazz would dispute that John Col-
tranersquos saxophone work improved during his tenure with pianist
Telonious Monkrsquos quartet or that it developed further in Col-
trane own ldquoclassic quartetrdquo (ndash)7 Here the assessment is
not quantitative or statistical but qualitative One might object
that this is a purely subjective judgment (such as whether one
feels hot or not) which is relative to the person hearing Who is
to judge Te answer is straightforward the one whose expe-
rience knowledge and wisdom merit approval Although manydrink wine there are few expert wine tasters A student of mine
is so adept at this art that he can tell what part of the country a
wine came from Not having developed this advanced degree of
skill this is foreign to me However I had no inclination to say
that my judgment on wine is as accurate as Markrsquos Along these
lines I was once embarrassed when one of my students told me
that the wine I was enjoying was ldquothe Kenny G of winesrdquo Tis as
jazz aficionados know was not a compliment about the wine or
about my taste for wine

non est disputandum Te avant-garde saxophone playing ofPeter Broumltzmann can send me into the upper reaches of aes-

beyond artistic judgments Notice the reference range (or extent)
of Protagorasrsquos statement ldquoMan is the measure of all thingsrdquomdash
matters of taste as well as matters of fact matters of principle
and matters of matter Nothing is excluded
Let us follow this out As we think it through the old Greek
will sound much like modern man If Protagoras is right then
there is no disputing matters of morality either Man is the
measure of what is right and what is wrong what is virtuous and
what is vicious what should be loved and what should be hatedmdash
just as Hamlet claimed oday this thinking is usually put in thelanguage of choice instead of measurement but the idea is the
same If you chose to do X that choice is the end of the matter
Or to suit Protagoras if you measure X as worth doing then it
is worth doing Tis is true whether X refers to sailing stealing
or stampeding cattle in the direction of a Cub Scout outing
But we might say ldquoWho is to judgerdquo Who of us can stand
above him- or herself and others and become objective Yes we
recoil from some ideasmdashsuch as torturing the innocent merely
for pleasure or female genital mutilation But what does that tell

Moral Philosophy Bundy said
I learned that all moral judgments are ldquovalue judgmentsrdquo
that all value judgments are subjective and that none can
be proved to be either ldquorightrdquo or ldquowrongrdquo I even read some-where that the Chief Justice of the United States had written
that the American Constitution expressed nothing more
than collective value judgments Believe it or not I figured
out for myselfmdashwhat apparently the Chief Justice couldnrsquot
figure out for himselfmdashthat if the rationality of one value
judgment was zero multiplying it by millions would not
make it one whit more rational Nor is there any ldquoreasonrdquo
to obey the law for anyone like myself who has the
boldness and daring ldquothe strength of characterrdquo to throw
off its shackles
I discovered that to become truly free truly unfettered
I had to become truly uninhibited And I quickly discovered
that the greatest obstacle to my freedom the greatest blockand limitation to it consists in the insupportable ldquovalue

be written in Chinese or in English Since each language uses
different symbols for writing its graphic inscription for cat will
differ Tis is true for voicing the word cat as well Trough a
long messy process not instigated by any central planning each
culture selects its own conventions of communication Are not
these two systems of writing measuring reality in very different
ways In point of fact they are not
Both kinds of writing systems (as well as other means ofcommunication) make claims about a reality that are outside
of the systems themselves and outside of the individuals who
use the pictographic or ideographic methods We tacitly saw
this earlier But in both cases a cat is invoked there is a single
referent Te differences in linguistic custom are not differ-
ences in content A cat is a cat in whatever language and it will
not bark however it may be measured Moreover while it may
be vexing in places one can translate a book from English to
Chinese Not everything is lost in translation in fact more is

Staying on matters of taste for a moment (and not morality

pectedly) childish Te apostle Paul notes this in a well-known
turn of phrase ldquoWhen I was a child I talked like a child I
thought like a child I reasoned like a child When I became a
man I put the ways of childhood behind merdquo ( Corinthians
see also Hebrews -)
Furthermore the very notion of improvement or progress
(not merely some change in quality) requires and assumes an
objective standard by which to measure improvement (or de-cline) If a baseball batter hits in and in he
has improved based on the best possible average of Tere
is a measurement and it is not the perception of the batter that
determines this measurement Tis is the case in the arts as well
Few knowledgeable about jazz would dispute that John Col-

not quantitative or statistical but qualitative One might object
that this is a purely subjective judgment (such as whether one
feels hot or not) which is relative to the person hearing Who is

lines I was once embarrassed when one of my students told me

But Herodotus may yet rescue Protagoras In his History the
ancient historian notes that Darius a king of ancient Persia (who
was a kind of premodern anthropologist because of his study of
cultural differences) called together some Greeks and askedthem what it would take to cannibalize their dead fathers Te
Greeks needed no time to ponder the proposition since nothing
would move them to such odious paternal desecration Teir
practice was cremation this alone would honor their dead Ten
Darius summoned several Callatians (from India) to join the
Greeks and asked them what would make them cremate their
deceased fathers Te Callatians were as horrified as the Greeks
had been and told Darius to not discuss such atrocities
Had Protagoras heard this he would likely applaud having
found more evidence for his outlook But not all applause is
earned While the Greeks and Callatians observed fundamen-
tally different funeral rites both cultures honored the dead Tat
is only particular practicesmdashnot just any old or new thingmdashwere esteemed right and good in the treatment of corpses and
these practices were not norms for the treatment of the living
In other words death was set apart as uniquely meaningful and
thus required that the living treat the dead with ritual respect
Tus Greeks and Callatians agreed on a deep principle of hon-
oring the dead Tey disagreed on the rule that stems from that
principle In no sense then does the example of cultural rela-
tivity disprove moral agreement across cultures since there was
deep agreement between the cultures C S Lewis makes just
this point in Mere Christianity

Protagoras
I know that some people say the idea of a Law of Nature or
decent behaviour known to all men is unsound because
different civilisations and different ages have had quite dif-
ferent moralities
But this is not true Tere have been differences between
their moralities but these have never amounted to any-
thing like a total difference If anyone will take the trouble
to compare the moral teaching of say the ancient Egyp-
tians Babylonians Hindus Chinese Greeks and Romanswhat will really strike him will be how very like they are to
each other and to our own9
Te case against Protagoras comes down to this If we want to
learn anything if we want to improve as human beings if we
want to condemn the ed Bundys of the world if we want any
kind of educated taste if we desire to understand and honorhumanity then we must reject the ldquoman is the measurerdquo theory
Each person is indeed the measurer of some things Some of
them the individual gets right some of them the individual gets
wrong And in this difference lies all the difference in the world
and even outside of it

mythology Eastern or Western) is simply that it is mythology it
is neither history nor clearly articulated philosophy In too many
ways the gods despite their thespian reacutesumeacutes and magical
powers were not much more than semi- glorified mortals Tis
was the objection of a growing group of Greeks who were mere
mortalsmdashmortals with meaning metaphysics and morality on
their minds And what might the mind do when free to explore
life and its questions apart from the venerable stories of Greek
fascination It might philosophize and so it didProtagoras and his cohorts quested for explanations of a more
abstract but also compelling sort than the old tales could afford
Tey sought principles to explain facts in a universal and logi-
cally coherent manner o be a little unfair to the mythologies
consider the tooth fairy She adds some magical benevolence to
the loss and placement of a baby tooth for children but the fairy
story adds nothing about the nature of benevolence the signifi-
cance of teeth or the significance of the humans who grow and
lose these teeth whether through development (teething) or
decay (the toothless)
Tus to give one example Tales of Miletus tried to find a
cosmic commonality to all things He divined it as water Yes
water which was more than rain oceans lakes and puddles Itwas everywhere so perhaps it was the root and branch of every-
thing Water or moisture in general lives in the clouds in plants
in animals (aquatic land or amphibious) and in thirsty mortals
It condenses and evaporates but never leaves the planet Con-
sidering the presence and power of water Tales extrapolated
that water was more than one more thing on earth however
necessary for life It was rather the unifying principle for exis-
tence Whatever we think of Tales his thinking is not absurd
and it indicates a thirst for philosophical explanation as opposed
to mythological meanderings At least he was trying

Protagoras
D W D R
But it is Protagoras who calls for our attention Instead of ar-guing for something at the heart of everything (water for Tales)
a principle found in nature Protagoras moved back from nature
to the self After all skeptics had questioned mere mortalsrsquo
ability to know with any confidence what is out there inde-
pendent of themselves Te jaundiced eye sees things differently
from the nonjaundiced eye Children perceive entities invisible
to adults Adults sometimes hallucinatemdashbut perhaps they areseeing what most miss One woman feels cold in a room of degF
and another feels hot Age alters hearing seeing memory and
may jangle judgments Te upshot is that we cannot find a place
to stand to see the world as it is We are simply ill-equipped to
do so Objective truth what is independent of our perceptions
endlessly and mercilessly eludes us
We will return to skepticism when discussing Descartes and
Pascal but Protagoras was not a skeptic He did not withhold
judgments about facts in themselves because we do not have the
ability to know them While recognizing that the skeptics had
dethroned our intellectual confidence in capturing objective re-
ality his point of departure was this we do know our own view-
points judgments and beliefs Tat is we measure things theydo not measure themselves So I take most of Francis Baconrsquos
paintings to be ugly and thus unattractive I am repulsed Tis is
the end of the story or my story Tis is my measurement You
on the contrary may find delight in Baconrsquos tortured figures and
color schemes Tat is your measurement and the end of your
story
Now reconsider the skeptical point made earlier One person
can deem the room cold and another hot Te skeptic might say
we cannot know then what the room is given the variability in
perception But Protagoras claims that the room is hot for person

Protagoras
I know that some people say the idea of a Law of Nature or
decent behaviour known to all men is unsound because
different civilisations and different ages have had quite dif-
ferent moralities
But this is not true Tere have been differences between
their moralities but these have never amounted to any-
thing like a total difference If anyone will take the trouble
to compare the moral teaching of say the ancient Egyp-
tians Babylonians Hindus Chinese Greeks and Romanswhat will really strike him will be how very like they are to
each other and to our own9
Te case against Protagoras comes down to this If we want to
learn anything if we want to improve as human beings if we
want to condemn the ed Bundys of the world if we want any
kind of educated taste if we desire to understand and honorhumanity then we must reject the ldquoman is the measurerdquo theory
Each person is indeed the measurer of some things Some of
them the individual gets right some of them the individual gets
wrong And in this difference lies all the difference in the world
and even outside of it

Protagoras
D W D R
But it is Protagoras who calls for our attention Instead of ar-guing for something at the heart of everything (water for Tales)
a principle found in nature Protagoras moved back from nature
to the self After all skeptics had questioned mere mortalsrsquo
ability to know with any confidence what is out there inde-
pendent of themselves Te jaundiced eye sees things differently
from the nonjaundiced eye Children perceive entities invisible
to adults Adults sometimes hallucinatemdashbut perhaps they areseeing what most miss One woman feels cold in a room of degF
and another feels hot Age alters hearing seeing memory and
may jangle judgments Te upshot is that we cannot find a place
to stand to see the world as it is We are simply ill-equipped to
do so Objective truth what is independent of our perceptions
endlessly and mercilessly eludes us
We will return to skepticism when discussing Descartes and
Pascal but Protagoras was not a skeptic He did not withhold
judgments about facts in themselves because we do not have the
ability to know them While recognizing that the skeptics had
dethroned our intellectual confidence in capturing objective re-
ality his point of departure was this we do know our own view-
points judgments and beliefs Tat is we measure things theydo not measure themselves So I take most of Francis Baconrsquos
paintings to be ugly and thus unattractive I am repulsed Tis is
the end of the story or my story Tis is my measurement You
on the contrary may find delight in Baconrsquos tortured figures and
color schemes Tat is your measurement and the end of your
story
Now reconsider the skeptical point made earlier One person
can deem the room cold and another hot Te skeptic might say
we cannot know then what the room is given the variability in
perception But Protagoras claims that the room is hot for person

A and not hot for person B Tere is no contradiction since we
are considering individual perceptions Tere are two measure-
ments each of which is valid Tus Bacon is barbaric to me and
beautiful to youmdashand that is the level best we can do Or perhaps
I will come to adore Baconrsquos paintings and heap scorn on my
former judgment If so then that is my measurement
Tis is rather attractive at first blush After all there is no
dispute in matters of taste or to be more snobby De gustibus
non est disputandum Te avant-garde saxophone playing ofPeter Broumltzmann can send me into the upper reaches of aes-
thetic delight while sending others scurrying from the room
while covering their ears But Protagoras took this insight far
beyond artistic judgments Notice the reference range (or extent)
of Protagorasrsquos statement ldquoMan is the measure of all thingsrdquomdash
matters of taste as well as matters of fact matters of principle
and matters of matter Nothing is excluded
Let us follow this out As we think it through the old Greek
will sound much like modern man If Protagoras is right then
there is no disputing matters of morality either Man is the
measure of what is right and what is wrong what is virtuous and
what is vicious what should be loved and what should be hatedmdash
just as Hamlet claimed oday this thinking is usually put in thelanguage of choice instead of measurement but the idea is the
same If you chose to do X that choice is the end of the matter
Or to suit Protagoras if you measure X as worth doing then it
is worth doing Tis is true whether X refers to sailing stealing
or stampeding cattle in the direction of a Cub Scout outing
But we might say ldquoWho is to judgerdquo Who of us can stand
above him- or herself and others and become objective Yes we
recoil from some ideasmdashsuch as torturing the innocent merely
for pleasure or female genital mutilation But what does that tell
us about reality if there really is such a thing as reality Te claim

Moral Philosophy Bundy said
I learned that all moral judgments are ldquovalue judgmentsrdquo
that all value judgments are subjective and that none can
be proved to be either ldquorightrdquo or ldquowrongrdquo I even read some-where that the Chief Justice of the United States had written
that the American Constitution expressed nothing more
than collective value judgments Believe it or not I figured
out for myselfmdashwhat apparently the Chief Justice couldnrsquot

judgment was zero multiplying it by millions would not
make it one whit more rational Nor is there any ldquoreasonrdquo

boldness and daring ldquothe strength of characterrdquo to throw

But Herodotus may yet rescue Protagoras In his History the
ancient historian notes that Darius a king of ancient Persia (who
was a kind of premodern anthropologist because of his study of
cultural differences) called together some Greeks and askedthem what it would take to cannibalize their dead fathers Te
Greeks needed no time to ponder the proposition since nothing
would move them to such odious paternal desecration Teir
practice was cremation this alone would honor their dead Ten
Darius summoned several Callatians (from India) to join the
Greeks and asked them what would make them cremate their
deceased fathers Te Callatians were as horrified as the Greeks
had been and told Darius to not discuss such atrocities
Had Protagoras heard this he would likely applaud having
found more evidence for his outlook But not all applause is
earned While the Greeks and Callatians observed fundamen-
tally different funeral rites both cultures honored the dead Tat
is only particular practicesmdashnot just any old or new thingmdashwere esteemed right and good in the treatment of corpses and
these practices were not norms for the treatment of the living
In other words death was set apart as uniquely meaningful and
thus required that the living treat the dead with ritual respect
Tus Greeks and Callatians agreed on a deep principle of hon-
oring the dead Tey disagreed on the rule that stems from that
principle In no sense then does the example of cultural rela-
tivity disprove moral agreement across cultures since there was
deep agreement between the cultures C S Lewis makes just
this point in Mere Christianity

Protagoras
I know that some people say the idea of a Law of Nature or
decent behaviour known to all men is unsound because
different civilisations and different ages have had quite dif-
ferent moralities
But this is not true Tere have been differences between
their moralities but these have never amounted to any-
thing like a total difference If anyone will take the trouble
to compare the moral teaching of say the ancient Egyp-
tians Babylonians Hindus Chinese Greeks and Romanswhat will really strike him will be how very like they are to
each other and to our own9
Te case against Protagoras comes down to this If we want to
learn anything if we want to improve as human beings if we
want to condemn the ed Bundys of the world if we want any
kind of educated taste if we desire to understand and honorhumanity then we must reject the ldquoman is the measurerdquo theory
Each person is indeed the measurer of some things Some of
them the individual gets right some of them the individual gets
wrong And in this difference lies all the difference in the world
and even outside of it

that ldquoman is the measure of all thingsrdquo is an all-encompassing
judgment itself Te answer to ldquoWho is to judgerdquo is that we are
the measure of all things Tat is there is nothing outside of
human judgment by which it might be judged But why would
Protagoras (or anyone else) consider that to be reality itself

Besides being a serial killer ed Bundy was a philosophical
thinker of the Protagorean type Remarkably his philosophy wascaught on tape before he raped and killed a young woman She
was one of dozens of his prey As reported in Louis Pojmanrsquos text
Moral Philosophy Bundy said
I learned that all moral judgments are ldquovalue judgmentsrdquo
that all value judgments are subjective and that none can
be proved to be either ldquorightrdquo or ldquowrongrdquo I even read some-where that the Chief Justice of the United States had written
that the American Constitution expressed nothing more
than collective value judgments Believe it or not I figured
out for myselfmdashwhat apparently the Chief Justice couldnrsquot
figure out for himselfmdashthat if the rationality of one value
judgment was zero multiplying it by millions would not
make it one whit more rational Nor is there any ldquoreasonrdquo
to obey the law for anyone like myself who has the
boldness and daring ldquothe strength of characterrdquo to throw
off its shackles
I discovered that to become truly free truly unfettered
I had to become truly uninhibited And I quickly discovered
that the greatest obstacle to my freedom the greatest blockand limitation to it consists in the insupportable ldquovalue
judgmentrdquo that I was bound to respect the rights of others
I asked myself who were these ldquoothersrdquo Other human

would move them to such odious paternal desecration Teir

Darius summoned several Callatians (from India) to join the
Greeks and asked them what would make them cremate their
deceased fathers Te Callatians were as horrified as the Greeks
had been and told Darius to not discuss such atrocities
Had Protagoras heard this he would likely applaud having
found more evidence for his outlook But not all applause is
earned While the Greeks and Callatians observed fundamen-
tally different funeral rites both cultures honored the dead Tat
is only particular practicesmdashnot just any old or new thingmdashwere esteemed right and good in the treatment of corpses and
these practices were not norms for the treatment of the living
In other words death was set apart as uniquely meaningful and
thus required that the living treat the dead with ritual respect

Protagoras
I know that some people say the idea of a Law of Nature or
decent behaviour known to all men is unsound because
different civilisations and different ages have had quite dif-
ferent moralities
But this is not true Tere have been differences between
their moralities but these have never amounted to any-
thing like a total difference If anyone will take the trouble
to compare the moral teaching of say the ancient Egyp-
tians Babylonians Hindus Chinese Greeks and Romanswhat will really strike him will be how very like they are to
each other and to our own9
Te case against Protagoras comes down to this If we want to
learn anything if we want to improve as human beings if we
want to condemn the ed Bundys of the world if we want any
kind of educated taste if we desire to understand and honorhumanity then we must reject the ldquoman is the measurerdquo theory
Each person is indeed the measurer of some things Some of
them the individual gets right some of them the individual gets
wrong And in this difference lies all the difference in the world
and even outside of it

human languages For example the general concept of cat may
be written in Chinese or in English Since each language uses
different symbols for writing its graphic inscription for cat will
differ Tis is true for voicing the word cat as well Trough a
long messy process not instigated by any central planning each
culture selects its own conventions of communication Are not
these two systems of writing measuring reality in very different
ways In point of fact they are not
Both kinds of writing systems (as well as other means ofcommunication) make claims about a reality that are outside
of the systems themselves and outside of the individuals who
use the pictographic or ideographic methods We tacitly saw
this earlier But in both cases a cat is invoked there is a single
referent Te differences in linguistic custom are not differ-
ences in content A cat is a cat in whatever language and it will
not bark however it may be measured Moreover while it may
be vexing in places one can translate a book from English to
Chinese Not everything is lost in translation in fact more is
found than is lost ranslators need have no fear of losing their
livelihood
Staying on matters of taste for a moment (and not morality
for now) are all people equally skilled in measurement Tepoet and literary critic S Eliot advocated the cultivation of
ldquoeducated tasterdquo Consider your preferences in music and
reading when you were quite young Tey are likely not the
same as when you became an adult You may still enjoy and
laugh at nursery rhymes but your tastes have expanded Yes
you still love Winnie the Pooh (and I mean the original Pooh
not the Walt Disney version) but you understand and appre-
ciate it more deeply now If so (and substitute your own ex-
amples here if needed) your tastes have at least changed and
have likely improved with age Your earlier judgments were

turn of phrase ldquoWhen I was a child I talked like a child I
thought like a child I reasoned like a child When I became a
man I put the ways of childhood behind merdquo ( Corinthians

Furthermore the very notion of improvement or progress
(not merely some change in quality) requires and assumes an
objective standard by which to measure improvement (or de-cline) If a baseball batter hits in and in he

determines this measurement Tis is the case in the arts as well

not quantitative or statistical but qualitative One might object
that this is a purely subjective judgment (such as whether one
feels hot or not) which is relative to the person hearing Who is
to judge Te answer is straightforward the one whose expe-

is so adept at this art that he can tell what part of the country a
wine came from Not having developed this advanced degree of
skill this is foreign to me However I had no inclination to say
that my judgment on wine is as accurate as Markrsquos Along these
lines I was once embarrassed when one of my students told me
that the wine I was enjoying was ldquothe Kenny G of winesrdquo Tis as
jazz aficionados know was not a compliment about the wine or
about my taste for wine
Artistic judgments involve much more than my quick treatment
