Now in this place, my dear Meno, we have a contrary state of things: a drought of wisdom, as it were, has come on; and it seems as though wisdom had deserted our borders in favour of yours. You have only to ask one of our people a question such as that, and he will be sure to laugh and say: Stranger, you must think me a specially favoured mortal, to be able to tell whether virtue can be taught, or in what way it comes to one: so far am I from knowing whether it can be taught or not, that I actually do not even know what the thing itself, virtue, is at all. And I myself, Meno, am in the same case; I share my townsmen’s poverty in this matter: I have to reproach myself with an utter ignorance about virtue; and if I do not know what a thing is, how can I know what its nature may be? Or do you imagine it possible, if one has no cognizance at all of Meno, that one could know whether he is handsome or rich or noble, or the reverse of these? Do you suppose that one could?
And there are very many other virtues besides, so that one cannot be at a loss to explain what virtue is; for it is according to each activity and age that every one of us, in whatever we do, has his virtue; and the same, I take it, Socrates, will hold also of vice.
I mean by hypothesis what the geometricians often do in dealing with a question put to them; for example, whether a certain area is capable of being inscribed as a triangular space in a given circle: they reply—I cannot yet tell whether it has that capability; but I think, if I may put it so, that I have a certain helpful hypothesis for the problem, and it is as follows: If this area is such that when you apply it to the given line of the circle you find it falls short by a space similar to that which you have just applied, then I take it you have one consequence, and if it is impossible for it to fall so, then some other. Accordingly I wish to put a hypothesis, before I state our conclusion as regards inscribing this figure in the circle by saying whether it is impossible or not. In the same way with regard to our question about virtue, since we do not know either what it is or what kind of thing it may be, we had best make use of a hypothesis in considering whether it can be taught or not, as thus: what kind of thing must virtue be in the class of mental properties, so as to be teachable or not? In the first place, if it is something dissimilar or similar to knowledge, is it taught or not—or, as we were saying just now, remembered? Let us have no disputing about the choice of a name: is it taught? Or is not this fact plain to everyone—that the one and only thing taught to men is knowledge?
and he retains undiminished to this day the high reputation he has enjoyed all that time—and not only Protagoras, but a multitude of others too: some who lived before him, and others still living. Now are we to take it, according to you, that they wittingly deceived and corrupted the youth, or that they were themselves unconscious of it? Are we to conclude those who are frequently termed the wisest of mankind to have been so demented as that?
