Yes, said Ctesippus; I should be mad to say anything else.
And in telling a lie, do you tell the thing of which you speak or not?
You tell the thing of which you speak.
And he who tells, tells that thing which he tells, and no other?
Yes, said Ctesippus.
And that is a distinct thing apart from other things?
Certainly.
And he who says that thing says that which is?
Yes.
And he who says that which is, says the truth. And therefore Dionysodorus, if he says that which is, says the truth of you and no lie.
