THEAETETUS: Most true.
SOCRATES: Thus, then, the assertion that knowledge and perception are one, involves a manifest impossibility?
THEAETETUS: Yes.
SOCRATES: Then they must be distinguished?
THEAETETUS: I suppose that they must.
SOCRATES: Once more we shall have to begin, and ask 'What is knowledge?' and yet, Theaetetus, what are we going to do?
THEAETETUS: About what?
SOCRATES: Like a good-for-nothing cock, without having won the victory, we walk away from the argument and crow.
THEAETETUS: How do you mean?
SOCRATES: After the manner of disputers (Lys.; Phaedo; Republic), we were satisfied with mere verbal consistency, and were well pleased if in this way we could gain an advantage. Although professing not to be mere Eristics, but philosophers, I suspect that we have unconsciously fallen into the error of that ingenious class of persons.
