STRANGER: But that sort of hireling whose conversation is pleasing and who baits his hook only with pleasure and exacts nothing but his maintenance in return, we should all, if I am not mistaken, describe as possessing flattery 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 many other things, which are purchased in one city, and carried away and sold in another--wares of the soul which are hawked about either for the sake of instruction or amusement;--may not he who takes them about and sells them be quite as truly called a merchant as he who sells meats and drinks? THEAETETUS: To be sure he may.
