SOCRATES: But if he is to have more power of persuasion than the physician, he will have greater power than he who knows?
GORGIAS: Certainly.
SOCRATES: Although he is not a physician:—is he?
GORGIAS: No.
SOCRATES: And he who is not a physician must, obviously, be ignorant of what the physician knows.
GORGIAS: Clearly.
SOCRATES: Then, when the rhetorician is more persuasive than the physician, the ignorant is more persuasive with the ignorant than he who has knowledge?—is not that the inference?
GORGIAS: In the case supposed:—yes.
SOCRATES: And the same holds of the relation of rhetoric to all the other arts; the rhetorician need not know the truth about things; he has only to discover some way of persuading the ignorant that he has more knowledge than those who know?
GORGIAS: Yes, Socrates, and is not this a great comfort?—not to have learned the other arts, but the art of rhetoric only, and yet to be in no way inferior to the professors of them?
