SOCRATES: Mark now the farther development. I shall only ask him, and not
teach him, and he shall share the enquiry with me: and do you watch and
see if you find me telling or explaining anything to him, instead of
eliciting his opinion. Tell me, boy, is not this a square of four feet
which I have drawn?

BOY: Yes.

SOCRATES: And now I add another square equal to the former one?

BOY: Yes.

SOCRATES: And a third, which is equal to either of them?

BOY: Yes.

SOCRATES: Suppose that we fill up the vacant corner?

BOY: Very good.

SOCRATES: Here, then, there are four equal spaces?

BOY: Yes.

SOCRATES: And how many times larger is this space than this other?

BOY: Four times.

SOCRATES: But it ought to have been twice only, as you will remember.
