o Many public speakers are engaged in audience analysis, which is the process of
evaluating an audience and its background (e.g., age, sex, educational level, etc.) and
tailoring one’s speech so that listeners respond as the speaker hopes they will.
o Aristotle observed, “Of the three elements in speech-making—speaker, subject, and
person addressed—it is the last one, the hearer, that determines the speech’s end and
object” (http://www.americanrhetoric.com/aristotleonrhetoric.htm).
• The second assumption underlying Aristotle’s theory pertains to what speakers do in their
speech preparation and their speech making.
• Aristotle’s proofs refer to the means of persuasion, and, for Aristotle, three proofs exist:
ethos, pathos, and logos.
o Ethos refers to the perceived character, intelligence, and goodwill of a speaker as
they become revealed through his or her speech.
▪ Eugene Ryan (1984) notes that ethos is a broad term that refers to the mutual
influence that speakers and listeners have on each other.
▪ Ethos, according to Kenneth Andersen, a communication ethicist, is
“something you create on the occasion” (p. 131). To that end, a speaker’s ethos
is not simply something that is brought into a speaking experience; it is the
speaking experience.
▪ Melissa Waresh (2012) contends that ethos must necessarily take into
consideration the relationship between speaker and audience.
o Logos is the logical proof that speakers employ—their arguments and
rationalizations. For Aristotle, logos involves using a number of practices, including
using logical claims and clear language.
o Pathos pertains to the emotions that are drawn out of listeners.
▪ Aristotle argues that listeners become the instruments of proof when emotion is
stirred in them; listeners judge differently when they are influenced by joy,
pain, hatred, or fear.
IV. The Syllogism: A Three-Tiered Argument
• The term syllogism, defined as a set of propositions that are related to one another and
draw a conclusion from the major and minor premises.
• Typically, syllogisms contain two premises and a conclusion.
• A syllogism is nothing more than a deductive argument, a group of statements (premises)
that lead to another group of statements (conclusions).
▪ In other words, premises are starting points or beginners used by speakers. They
establish justification for a conclusion. In a syllogism, both major and minor
premises exist.
• However, in an often complex and convoluted society, drawing such a clear conclusion
