STRANGER: Yet I suspect that he will furnish us with the sort of definition and line of enquiry which we want.
THEAETETUS: Very good.
STRANGER: Let us begin by asking whether he is a man having art or not having art, but some other power.
THEAETETUS: He is clearly a man of art.
STRANGER: And of arts there are two kinds?
THEAETETUS: What are they?
STRANGER: There is agriculture, and the tending of mortal creatures, and the art of constructing or moulding vessels, and there is the art of imitation—all these may be appropriately called by a single name.
THEAETETUS: What do you mean? And what is the name?
STRANGER: He who brings into existence something that did not exist before is said to be a producer, and that which is brought into existence is said to be produced.
THEAETETUS: True.
