Do you know what sort of things are called just?The things that the laws command.Consequently those who do what the laws command do both what is just and what they must do?Of course.And are not they who do what is just, just men?I think so.Do you think then, that any obey the laws without knowing what the laws command?I do not.And knowing what they must do, do you suppose that any think they must not do it?I don’t think so.Do you know of any who do, not what they think they must do, but something else?I do not.Consequently those who know what is lawful concerning men do what is just?Certainly.But are not they who do what is just, just men?Exactly.At last, then, we may rightly define just men as those who know best what is just concerning men?I think so.And what of Wisdom?

How shall we describe it? Tell me, does it seem to you that the wise are wise about what they know, or are some wise about what they do not know?About what they know, obviously; for how can a man be wise about the things he doesn’t know?The wise, then, are wise by knowledge?How else can a man be wise if not by knowledge?Do you think that wisdom is anything but that by which men are wise?No.It follows that Wisdom is Knowledge?I think so.Then do you think it possible for a man to know all things?Of course not — nor even a fraction of them.So an all-wise man is an impossibility?Of course, of course.Consequently everyone is wise just in so far as he knows?I think so.
