CORE DEFINITION

Ethos (credibility/persona), Pathos (emotion/empathy), Logos (logic/facts). Perfect persuasive writing must possess all three elements.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Self-check for persuasiveness. Examine your writing: Have you demonstrated expertise (Ethos)? Have you touched the reader's emotions (Pathos)? Is your argument rigorous (Logos)? All are indispensable.

Aristotle's 'Rhetoric' proposes three elements of persuasion: Ethos (the speaker's credibility/expertise and character), Pathos (the arousal of audience emotions), and Logos (the logic and evidence of the argument). The three must work together—without Ethos, no one trusts; without Pathos, it fails to move; without Logos, it cannot stand. Persuasion is a balance of the three, not a single point.

MINIMUM ACTION

In progress 0/3

Practice this model in one real situation:

Before writing/speaking, self-check the triangle: Have I established Ethos (qualifications/credibility)? Have I touched Pathos (audience concerns/emotions)? Is Logos rigorous (evidence/structure)? 2) Strengthen the weak side according to the audience
Avoid piling up logic alone (cold) or only emotional appeal without evidence
Adapt the triangle to different scenarios (academic emphasizes Logos, fundraising emphasizes Pathos).
