Boy: Everyone at school knows that, Socrates.
Socrates: Well, maybe. However, it is about that side, which when multiplied time itself yields an area of two, that I would like to speak further today. How is that with you?
Boy: That is fine, Socrates. I remember that line, and I sort of liked it the best, if you know what I mean.
Socrates: Good, then we should have a great time.
Do you know how long that line is, boy?
Boy: Well, I know that you both thought it wise when I said it was of a length which when made a square of, yielded a square with an area of two, so I suppose I should answer that way.
Socrates: And a good answer it is, too. We are going to make it an even better answer as we proceed.
Boy: Good.
Socrates: Do you remember when you tripped up and fell on your face the other day, when you thought that the square of area nine was actually a square of area eight?
Boy: Oh yes, Socrates! And I am sorely ashamed, because I still do not know enough to make sure I never make such an error again, and therefore I know my virtue and rightness are lacking.
Socrates: They are not lacking so much that they cannot be improved, are they boy?
