THEAETETUS: Well, Socrates, I will answer as you and he bid me; and if I make a mistake, you will doubtless correct me.
SOCRATES: We will, if we can.
THEAETETUS: Then, I think that the sciences which I learn from Theodorus—geometry, and those which you just now mentioned—are knowledge; and I would include the art of the cobbler and other craftsmen; these, each and all of, them, are knowledge.
SOCRATES: Too much, Theaetetus, too much; the nobility and liberality of your nature make you give many and diverse things, when I am asking for one simple thing.
THEAETETUS: What do you mean, Socrates?
SOCRATES: Perhaps nothing. I will endeavour, however, to explain what I believe to be my meaning: When you speak of cobbling, you mean the art or science of making shoes?
THEAETETUS: Just so.
SOCRATES: And when you speak of carpentering, you mean the art of making wooden implements?
THEAETETUS: I do.
SOCRATES: In both cases you define the subject matter of each of the two arts?
