For as I like a man in whom there is something of the old, so I like a man in whom there is something of the young; and he who follows this maxim, in body will possibly be an old man but he will never be an old man in mind.
I conclude, then, that the plea of having acted in the interests of a friend is not a valid excuse for a wrong action. . . . We may then lay down this rule of friendship--neither ask nor consent to do what is wrong. For the plea "for friendship's sake" is a discreditable one, and not to be admitted for a moment.
