Thermippos — The Complete Dialogue
The scene is the agora, outside the office of the magistrate. Socrates is on his way to answer charges of impiety. There he meets Thermippos holding forth confidently amidst a gathering of young men. Naturally, since death is on his mind, Socrates seizes the opportunity to discuss the subject with a man who seems certain of everything.

Thermippos. I do.
Socrates. And you agree furthermore that I am a man.
Thermippos. I have no reason to doubt it, Socrates.
Socrates. Surely then you agree that I am mortal.
Thermippos. I didn’t say that. You did. Don’t put words in my mouth.

Socrates. But no true reasoner could fail —
Thermippos. Ah, the no-true-Macedonian fallacy.

Socrates. I see, Thermippos. You’re an idiot.
Thermippos. And that’s an ad hominem.
