STRANGER: Then that part of the acquisitive art which exchanges, and of

exchange which either sells a man's own productions or retails those

of others, as the case may be, and in either way sells the knowledge of

virtue, you would again term Sophistry?

THEAETETUS: I must, if I am to keep pace with the argument.

STRANGER: Let us consider once more whether there may not be yet another

aspect of sophistry.

THEAETETUS: What is it?

STRANGER: In the acquisitive there was a subdivision of the combative or

fighting art.

THEAETETUS: There was.

STRANGER: Perhaps we had better divide it.

THEAETETUS: What shall be the divisions?

STRANGER: There shall be one division of the competitive, and another of

the pugnacious.

THEAETETUS: Very good.
