Rhetorical appeals: ethos

This lesson focuses on rhetorical appeals: ethos. Effective communication is fundamental to academic and professional success.

Rhetoric is the art of persuasion. Aristotle identified three main appeals: Ethos (credibility and character—"As a doctor, I know that..."), Pathos (emotional appeal—vivid stories, images, language that evokes feeling), Logos (logical appeal—facts, statistics, reasoning, evidence). Kairos refers to the right moment—a persuasive message must suit its time and context. Effective persuasion typically combines all three; over-reliance on one weakens an argument. Analyzing rhetoric means asking: Who is the author? What is their purpose? Who is the audience? What appeals do they use? How effective are they? This analysis applies to speeches, advertisements, essays, political messages—any text trying to change minds or behavior.

As you engage with this material, consider both the theoretical foundations and practical applications. Think critically about how this concept builds on prior knowledge and where you might apply it beyond the classroom.

Challenge yourself to go beyond memorization—seek to understand the "why" behind the processes and principles.
