• A. A Greek general
• B. The author of The Prince
• C. The father of modern science
• D. The philosopher who introduced the concept of ethos as one of the three modes of persuasion in rhetoric

Answer: (D)

Ethos is about the speaker’s character and credibility, a crucial factor Aristotle identified for persuading an audience. He taught that credibility—showing competence, good will, and ethical character—helps people trust and accept the argument even before it’s made. This idea sits alongside logos (logic) and pathos (emotion) as the three ways to persuade, with Aristotle arguing that audiences are more receptive when they believe the speaker is knowledgeable and has their best interests at heart. The other descriptions don’t capture how Aristotle formalized this rhetorical framework, whereas the philosopher who introduced ethos in rhetoric did so as part of his broader treatment of persuasive communication.
