03 · The mix-up

Where the confusion comes from

The mix-up“Ethos, pathos and logos are three co-equal pillars, with kairos as a fourth.”
What's true

They're three technical means of persuasion, and Aristotle does not treat them as equals — though the text pulls both ways: Book I chapter 1 calls the enthymeme the substance of rhetorical persuasion, while chapter 2 calls character almost the most effective means of proof. Kairos doesn't appear as a fourth mode at all; he consistently affirms only three.
