STRANGER: Alas, Theaetetus, methinks that we are now only beginning to see the real difficulty of the enquiry into the nature of it.

THEAETETUS: What do you mean?

STRANGER: O my friend, do you not see that nothing can exceed our ignorance, and yet we fancy that we are saying something good?

THEAETETUS: I certainly thought that we were; and I do not at all understand how we never found out our desperate case.

STRANGER: Reflect: after having made these admissions, may we not be justly asked the same questions which we ourselves were asking of those who said that all was hot and cold?

THEAETETUS: What were they? Will you recall them to my mind?

STRANGER: To be sure I will, and I will remind you of them, by putting the same questions to you which I did to them, and then we shall get on.

THEAETETUS: True.

STRANGER: Would you not say that rest and motion are in the most entire opposition to one another?

THEAETETUS: Of course.
