SOCRATES: What sort of discourse, Gorgias?—such discourse as would teach the sick under what treatment they might get well?
GORGIAS: No.
SOCRATES: Then rhetoric does not treat of all kinds of discourse?
GORGIAS: Certainly not.
SOCRATES: And yet rhetoric makes men able to speak?
GORGIAS: Yes.
SOCRATES: And to understand that about which they speak?
GORGIAS: Of course.
SOCRATES: But does not the art of medicine, which we were just now mentioning, also make men able to understand and speak about the sick?
GORGIAS: Certainly.
