ery or an art of making things pleasant.

THEAETETUS: Certainly.

STRANGER: And that sort, which professes to form acquaintances only for
the sake of virtue, and demands a reward in the shape of money, may be
fairly called by another name?

THEAETETUS: To be sure.

STRANGER: And what is the name? Will you tell me?

THEAETETUS: It is obvious enough; for I believe that we have discovered
the Sophist: which is, as I conceive, the proper name for the class
described.

STRANGER: Then now, Theaetetus, his art may be traced as a branch of the
appropriative, acquisitive family--which hunts animals,--living--land--
tame animals; which hunts man,--privately--for hire,--taking money in
exchange--having the semblance of education; and this is termed
Sophistry, and is a hunt after young men of wealth and rank--such is the
conclusion.

THEAETETUS: Just so.

STRANGER: Let us take another branch of his genealogy; for he is a
professor of a great and many-sided art; and if we look back at what has
preceded we see that he presents another aspect, besides that of which
we are speaking.

THEAETETUS: In what respect?

STRANGER: There were two sorts of acquisitive art; the one concerned
with hunting, the other with exchange.

THEAETETUS: There were.

STRANGER: And of the art of exchange there are two divisions, the one of
giving, and the other of selling.

THEAETETUS: Let us assume that.

STRANGER: Next, we will suppose the art of selling to be divided into
two parts.

THEAETETUS: How?

STRANGER: There is one part which is distinguished as the sale of a
man's own productions; another, which is the exchange of the works of
others.

THEAETETUS: Certainly.

STRANGER: And is not that part of exchange which takes place in the
city, being about half of the whole, termed retailing?

THEAETETUS: Yes.

STRANGER: And that which exchanges the goods of one city for those of
another by selling and buying is the exchange of the merchant?

THEAETETUS: To be sure.

STRANGER: And you are aware that this exchange of the merchant is of
two kinds: it is partly concerned with food for the use of the body,
and partly with the food of the soul which is bartered and received in
exchange for money.

THEAETETUS: What do you mean?

STRANGER: You want to know what is the meaning of food for the soul; the
other kind you surely understand.

THEAETETUS: Yes.

STRANGER: Take music in general and painting and marionette playing and
man
