Thank You for Arguing
Jay Heinrichs · 2007
"Aristotle's three levers of persuasion — ethos (credibility), pathos (emotion), and logos (logic) — still explain why arguments land or fail, and knowing which one is missing from a failed pitch tells you exactly what to fix."
A former magazine editor turned rhetoric obsessive rebuilt Aristotle's 2,300-year-old persuasion framework for modern arguments — sales pitches, political speeches, family disputes — and found it explained failures that felt mysterious in the moment.
Ethos is why the audience should trust you as the speaker — established through demonstrated competence, disinterest (not obviously self-serving), or values shared with the audience, not just claimed authority. Pathos moves the audience emotionally, and Heinrichs stresses it's not manipulation when used honestly — it's recognizing that decisions are made emotionally and justified rationally after the fact, so ignoring emotion means losing arguments to people who don't. Logos is the actual logical structure of the case — premises and evidence leading to a conclusion — and Heinrichs argues logos alone rarely persuades, because an airtight argument nobody trusts or feels invested in still fails. His diagnostic move for a failed pitch: identify which of the three was weakest, rather than assuming the content itself was wrong.
Why does Heinrichs argue that logos (logical argument) alone rarely persuades an audience?

Made to Stick
"Ideas that persuade and spread share six identifiable traits — the SUCCESS framework — while most ideas that fail to stick lack them despite being just as true or important."
