The Socratic Method

Ask, don't tell. Define and refute until knowledge proves itself or fails.

Socrates does not lecture. He asks his interlocutor to define a virtue — courage, justice, piety — and then patiently produces counterexamples that show the definition fails. The interlocutor is forced to either refine the definition or admit ignorance. Many admit ignorance and hate him for it. The method survives in every law school, every philosophy seminar, and every well-run conversation.
