CHAEREPHON: My question is this: If Gorgias had the skill of his brother
Herodicus, what ought we to call him? Ought he not to have the name which
is given to his brother?

POLUS: Certainly.

CHAEREPHON: Then we should be right in calling him a physician?

POLUS: Yes.

CHAEREPHON: And if he had the skill of Aristophon the son of Aglaophon, or
of his brother Polygnotus, what ought we to call him?

POLUS: Clearly, a painter.

CHAEREPHON: But now what shall we call him--what is the art in which he is
skilled.

POLUS: O Chaerephon, there are many arts among mankind which are
experimental, and have their origin in experience, for experience makes the
days of men to proceed according to art, and inexperience according to
chance, and different persons in different ways are proficient in different
arts, and the best persons in the best arts. And our friend Gorgias is one
of the best, and the art in which he is a proficient is the noblest.

SOCRATES: Polus has been taught how to make a capital speech, Gorgias; but
he is not fulfilling the promise which he made to Chaerephon.

GORGIAS: What do you mean, Socrates?
