Persuasive speaking can be contrasted with informative
speaking.
There are several points of contrast…
The Question of Fact.
• This refers to something that we can know to be either true or false, but right now we can argue about it.
• Examples include: historical controversy, predictions, or questions of existence.
To persuade my audience
that Lee Harvey
Oswald acted alone when
assassinating President John
F. Kennedy.
The Question of Value.
Here we can argue whether something is right or wrong,
moral or immoral, or better or worse than another thing.
The Question of Policy.
• Here is where we argue that some action should or should not be taken.
• The form is always:“To persuade my audience that X should do
Y.”
To persuade my audience that the US military should lift its
ban on allowing women to fight on the
front line.
Fact, Value and Policy Exercise Determine if the following statements focus on the question of fact, value or policy.

Methods of PersuasionAristotle
(384-322 B.C.)
• Greek teacher/scientist
• His work, the Rhetoric, is widely regarded as the most important work on persuasion every published.
• He tackled the question…
How do we come to believe something or to believe we should
act in a certain way in the absence of
knowing “the truth”?
3 Major Modes of Proof
Think of it as 3 ways that people are persuaded or that we come to
believe things or to act upon things.
Ethos“ethical” – credibility appeal
• Sometimes we come to believe something or to act upon something simply because someone we trusted told us it was so.
• Aristotle suggests that the source of the material is the MOST powerful mode of persuasion.
Pathos“pathetic” – emotional appeal
• Sometimes we come to believe something or to act upon something simply because of a gut feeling of an appeal to our emotions.
• We act out of fear and greed and also out of love and compassion.
• We even act in certain ways because we are concerned about what others will think of us.
Logos“logical” – rational appeal
• Sometimes we come to believe something or to act upon something simply because someone gave us what we considered to be a “good reason.”
• Here is where we consider evidence and reasoning as parts of the persuasive process.
• This is the most complicated mode of proof.
• Use of support materials (examples, statistics, and testimonies) constitute offering “good reasons” to accept a claim.
