Ethics and Spoken Communication Persuasive Appeals see Silva Rhetoricae:
How do you persuade someone? • You offer 3 kinds of intrinsic proof: • logos appeal to reason • pathos appeal to emotion • ethos persuasive appeal of one’s character • Mostly, you use some combination of all three.
What appeals are these speakers using? • Bill Gates (Microsoft) • Dean Kamen (TED Conference) • Luis van Ahn (Carnegie Mellon)
Ethos: “projection of character and credibility” (Gurak 2004) • How do you build credibility in a talk? • How do you convey trustworthiness?
How is “projection” of trustworthiness an ethical issue? • What is the relationship of ethos, ethics, and authority? • What are your responsibilities as a presenter, especially when you know a lot more information than the audience?
