BOOK I
Part 1
"A !en by natre desire to #no$. An indication o% this is the deli&ht
$e ta#e in or senses' %or e(en apart %ro! their se%lness they are
lo(ed %or the!sel(es' and abo(e all others the sense o% si&ht. )or
not only $ith a (ie$ to action* bt e(en $hen $e are not &oin& to
do anythin&* $e pre%er seein& +one !i&ht say, to e(erythin& else.
The reason is that this* !ost o% all the senses* !a#es s #no$ and
brin&s to li&ht !any di%%erences bet$een thin&s.
"By natre ani!als are born $ith the %aclty o% sensation* and %ro!sensation !e!ory is prodced in so!e o% the!* tho&h not in others.
And there%ore the %or!er are !ore intelli&ent and apt at learnin&
than those $hich cannot re!e!ber' those $hich are incapable o% hearin&
sonds are intelli&ent tho&h they cannot be ta&ht* e.&. the bee*
and any other race o% ani!als that !ay be li#e it' and those $hich
besides !e!ory ha(e this sense o% hearin& can be ta&ht.
"The ani!als other than !an li(e by appearances and !e!ories* and
ha(e bt little o% connected eperience' bt the h!an race li(es
also by art and reasonin&s. o$ %ro! !e!ory eperience is prodced
in !en' %or the se(eral !e!ories o% the sa!e thin& prodce %inally
the capacity %or a sin&le eperience. And eperience see!s pretty
!ch li#e science and art* bt really science and art co!e to !en
thro&h eperience' %or /eperience !ade art/* as Pols says* /bt
ineperience lc#./ o$ art arises $hen %ro! !any notions &ained by
eperience one ni(ersal 0d&e!ent abot a class o% ob0ects is prodced.
)or to ha(e a 0d&e!ent that $hen allias $as ill o% this disease
this did hi! &ood* and si!ilarly in the case o% 2ocrates and in !any
indi(idal cases* is a !atter o% eperience' bt to 0d&e that it
has done &ood to all persons o% a certain constittion* !ar#ed o%%
in one class* $hen they $ere ill o% this disease* e.&. to phle&!atic
or bilios people $hen brnin& $ith %e(ers-this is a !atter o% art.
"With a (ie$ to action eperience see!s in no respect in%erior to
art* and !en o% eperience scceed e(en better than those $ho ha(e
theory $ithot eperience. +The reason is that eperience is #no$led&e
o% indi(idals* art o% ni(ersals* and actions and prodctions areall concerned $ith the indi(idal' %or the physician does not cre
!an* ecept in an incidental $ay* bt allias or 2ocrates or so!e
other called by so!e sch indi(idal na!e* $ho happens to be a !an.
I%* then* a !an has the theory $ithot the eperience* and reco&ni3es
the ni(ersal bt does not #no$ the indi(idal inclded in this* he
$ill o%ten %ail to cre' %or it is the indi(idal that is to be cred.,
Bt yet $e thin# that #no$led&e and nderstandin& belon& to art rather
than to eperience* and $e sppose artists to be $iser than !en o%
eperience +$hich i!plies that Wisdo! depends in all cases rather

on #no$led&e,' and this becase the %or!er #no$ the case* bt the
latter do not. )or !en o% eperience #no$ that the thin& is so* bt
do not #no$ $hy* $hile the others #no$ the /$hy/ and the case. 4ence
$e thin# also that the !aster$or#ers in each cra%t are !ore honorable
and #no$ in a trer sense and are $iser than the !anal $or#ers* becase
they #no$ the cases o% the thin&s that are done +$e thin# the !anal
$or#ers are li#e certain li%eless thin&s $hich act indeed* bt act
$ithot #no$in& $hat they do* as %ire brns*-bt $hile the li%eless
thin&s per%or! each o% their %nctions by a natral tendency* the
laborers per%or! the! thro&h habit,' ths $e (ie$ the! as bein&
$iser not in (irte o% bein& able to act* bt o% ha(in& the theory
%or the!sel(es and #no$in& the cases. And in &eneral it is a si&n
o% the !an $ho #no$s and o% the !an $ho does not #no$* that the %or!er
can teach* and there%ore $e thin# art !ore trly #no$led&e than
eperience
is' %or artists can teach* and !en o% !ere eperience cannot.
"A&ain* $e do not re&ard any o% the senses as Wisdo!' yet srely these
&i(e the !ost athoritati(e #no$led&e o% particlars. Bt they do
not tell s the /$hy/ o% anythin&-e.&. $hy %ire is hot' they only
say that it is hot.
"At %irst he $ho in(ented any art $hate(er that $ent beyond the co!!on
perceptions o% !an $as natrally ad!ired by !en* not only becase
there $as so!ethin& se%l in the in(entions* bt becase he $as tho&ht
$ise and sperior to the rest. Bt as !ore arts $ere in(ented* and
so!e $ere directed to the necessities o% li%e* others to recreation*
the in(entors o% the latter $ere natrally al$ays re&arded as $iser
than the in(entors o% the %or!er* becase their branches o% #no$led&e
did not ai! at tility. 4ence $hen all sch in(entions $ere already
established* the sciences $hich do not ai! at &i(in& pleasre or at
the necessities o% li%e $ere disco(ered* and %irst in the places $here
!en %irst be&an to ha(e leisre. This is $hy the !athe!atical arts
$ere %onded in 5&ypt' %or there the priestly caste $as allo$ed to
be at leisre.
"We ha(e said in the 5thics $hat the di%%erence is bet$een art and
science and the other #indred %aclties' bt the point o% or present
discssion is this* that all !en sppose $hat is called Wisdo! to
deal $ith the %irst cases and the principles o% thin&s' so that*
as has been said be%ore* the !an o% eperience is tho&ht to be $iser
than the possessors o% any sense-perception $hate(er* the artist $iser
than the !en o% eperience* the !aster$or#er than the !echanic* and
the theoretical #inds o% #no$led&e to be !ore o% the natre o% Wisdo!
than the prodcti(e. learly then Wisdo! is #no$led&e abot certain
principles and cases.

"2ch and so !any are the notions* then* $hich $e ha(e abot Wisdo!

!st belon& to hi! $ho has in the hi&hest de&ree ni(ersal #no$led&e'
%or he #no$s in a sense all the instances that %all nder the ni(ersal.
And these thin&s* the !ost ni(ersal* are on the $hole the hardest
%or !en to #no$' %or they are %arthest %ro! the senses. And the !ost
eact o% the sciences are those $hich deal !ost $ith %irst principles'
%or those $hich in(ol(e %e$er principles are !ore eact than those
$hich in(ol(e additional principles* e.&. arith!etic than &eo!etry.
Bt the science $hich in(esti&ates cases is also instrcti(e* in

"That it is not a science o% prodction is clear e(en %ro! the history
o% the earliest philosophers. )or it is o$in& to their $onder that
!en both no$ be&in and at %irst be&an to philosophi3e' they $ondered

$ere o% the natre o% !atter $ere the only principles o% all thin&s.
That o% $hich all thin&s that are consist* the %irst %ro! $hich they
co!e to be* the last into $hich they are resol(ed +the sbstance
re!ainin&*
bt chan&in& in its !odi%ications,* this they say is the ele!ent and
this the principle o% thin&s* and there%ore they thin# nothin& is
either &enerated or destroyed* since this sort o% entity is al$ays
conser(ed* as $e say 2ocrates neither co!es to be absoltely $hen
he co!es to be beati%l or !sical* nor ceases to be $hen loses these

!st be so!e entity-either one or !ore than one-%ro! $hich all other
thin&s co!e to be* it bein& conser(ed.
":et they do not all a&ree as to the n!ber and the natre o% these
principles. Thales* the %onder o% this type o% philosophy* says the
principle is $ater +%or $hich reason he declared that the earth rests
on $ater,* &ettin& the notion perhaps %ro! seein& that the ntri!ent
o% all thin&s is !oist* and that heat itsel% is &enerated %ro! the
!oist and #ept ali(e by it +and that %ro! $hich they co!e to be is
a principle o% all thin&s,. 4e &ot his notion %ro! this %act* and%ro! the %act that the seeds o% all thin&s ha(e a !oist natre* and
that $ater is the ori&in o% the natre o% !oist thin&s.
"2o!e thin# that e(en the ancients $ho li(ed lon& be%ore the present
&eneration* and %irst %ra!ed acconts o% the &ods* had a si!ilar (ie$
o% natre' %or they !ade Ocean and Tethys the parents o% creation*
and described the oath o% the &ods as bein& by $ater* to $hich they
&i(e the na!e o% 2ty' %or $hat is oldest is !ost honorable* and
the !ost honorable thin& is that by $hich one s$ears. It !ay perhaps
be ncertain $hether this opinion abot natre is pri!iti(e and ancient*
bt Thales at any rate is said to ha(e declared hi!sel% ths abot
the %irst case. 4ippo no one $old thin# %it to inclde a!on& these
thin#ers* becase o% the paltriness o% his tho&ht.
"Anai!enes and Dio&enes !a#e air prior to $ater* and the !ost pri!ary
o% the si!ple bodies* $hile 4ippass o% Metaponti! and 4eraclits
o% 5phess say this o% %ire* and 5!pedocles says it o% the %or ele!ents

he says* al$ays re!ain and do not co!e to be* ecept that they co!e

o% one.
"Anaa&oras o% la3o!enae* $ho* tho&h older than 5!pedocles* $as
later in his philosophical acti(ity* says the principles are in%inite
in n!ber' %or he says al!ost all the thin&s that are !ade o% parts
li#e the!sel(es* in the !anner o% $ater or %ire* are &enerated and
destroyed in this $ay* only by a&&re&ation and se&re&ation* and arenot in any other sense &enerated or destroyed* bt re!ain eternally.

+%or this is a pri!iti(e belie%* and all a&reed in it,* bt also o%
all other chan&e' and this (ie$ is pecliar to the!. O% those $ho
said the ni(erse $as one* then none scceeded in disco(erin& a case
o% this sort* ecept perhaps Par!enides* and he only inas!ch as he
spposes that there is not only one bt also in so!e sense t$o cases.
Bt %or those $ho !a#e !ore ele!ents it is !ore possible to state
the second case* e.&. %or those $ho !a#e hot and cold* or %ire and

%its it to !o(e thin&s* and $ater and earth and sch thin&s they treat
in the contrary $ay.
"When these !en and the principles o% this #ind had had their day*as the latter $ere %ond inade7ate to &enerate the natre o% thin&s
