STRANGER: The latter should have two names,--one descriptive of the sale

of the knowledge of virtue, and the other of the sale of other kinds of

knowledge.

THEAETETUS: Of course.

STRANGER: The name of art-seller corresponds well enough to the latter;

but you must try and tell me the name of the other.

THEAETETUS: He must be the Sophist, whom we are seeking; no other name

can possibly be right.

STRANGER: No other; and so this trader in virtue again turns out to

be our friend the Sophist, whose art may now be traced from the art of

acquisition through exchange, trade, merchandise, to a merchandise of

the soul which is concerned with speech and the knowledge of virtue.

THEAETETUS: Quite true.

STRANGER: And there may be a third reappearance of him;--for he may

have settled down in a city, and may fabricate as well as buy these same

wares, intending to live by selling them, and he would still be called a

Sophist?

THEAETETUS: Certainly.
