"Ah. Stupid people never do the wrong thing. They get their reasoning wrong. Like the fellow who says all dogs are pets and all dogs bark, and cats are pets, too, and
therefore cats bark. Or that all Athenians are mortal, and all the citizens of Piraeus
are mortal, so all the citizens of Piraeus are Athenians."
"Which they are."
"Yes, but only accidentally. Who's stupid will occasionally say something that's right, but he says it for the wrong reason."
"You mean it's okay to say something that's wrong as long as the reason is right."
"Of course. Why else go to the trouble of being a rational animal?"
"All great apes evolved from lower life forms, man evolved from lower life forms,
therefore man is a great ape."
"Not bad."
