In most of the Socratic dialogues, Socrates professes to inquire into some virtue. At the same time, he professes not to know what the virtue in question is. How, then, can he inquire into it? Doesn't he need some knowledge to guide his inquiry? Socrates' disclaimer of knowledge seems to preclude Socratic inquiry. This difficulty must confront any reader of the Socratic dialogues; but one searches them in vain for any explicit statement of the problem or for any explicit solution (...) to it. The Meno, by contrast, both raises it explicitly and proposes a solution. (shrink)
