But if a man admit another to his friendship as a good man, and he becomes and shows himself to be a bad man, is he still to be loved? Perhaps we may answer that it is impossible, as it is not everything that is lovable, but only the good. A bad man, then, is not lovable, and ought not to be loved: for we ought not to love what is bad, nor to make ourselves like what is worthless; but, as we said before, it is like that makes friends with like.

Is the friendship, then, to be immediately broken off? Perhaps not in all cases, but only in the case of those who are incurably bad: when their reformation is possible, we are more bound to help them in their character than their fortune, inasmuch as character is a nobler thing, and has more to do with friendship than fortune has. But a man who withdraws his friendship in such a case, would seem to do nothing unnatural; for it was not with such a man that he made friends: his friend has become another man, and as he cannot restore him, he stands aloof from him.
