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.
