Are we then to break with him instantly? not in all cases; only where our friends are incurably depraved; when there is a chance of amendment we are bound to aid in repairing the moral character of our friends even more than their substance, in proportion as it is better and more closely related to Friendship. Still he who should break off the connection is not to be judged to act wrongly, for he never was a friend to such a character as the other now is, and therefore, since the man is changed and he cannot reduce him to his original state, he backs out of the connection. To put another case: suppose that one party remains what he was when the Friendship was formed, while the other becomes morally improved and widely different from his friend in goodness; is the improved character to treat the other as a friend? May we not say it is impossible? The case of course is clearest where there is a great difference, as in the Friendships of boys: for suppose that of two boyish friends the one still continues a boy in mind and the other becomes a man of the highest character, how can they be friends? since they neither are pleased with the same objects nor like and dislike the same things: for these points will not belong to them as regards one another, and without them it was assumed they cannot be friends because they cannot live in intimacy: and of the case of those who cannot do so we have spoken before. Well then, is the improved party to bear himself towards his former friend in no way differently to what he would have done had the connection never existed? Surely he ought to bear in mind the intimacy of past times, and just as we think ourselves bound to do favours for our friends in preference to strangers, so to those who have been friends and are so no longer we should allow somewhat on the score of previous Friendship, whenever the cause of severance is not excessive depravity on their part. Chapter IV. Now the friendly feelings which are exhibited towards our friends, and by which Friendships are characterised, seem to have sprung out of those which we entertain toward ourselves. I mean, people define a friend to be “one who intends and does what is good (or what he believes to be good) to another for that other’s sake,” or “one who wishes his friend to be and to live for that friend’s own sake” (which is the feeling of mothers towards their children, and of friends who have come into collision). Others again, “one who lives with another and chooses the same objects,” or “one who sympathises with his friend in his sorrows and in his joys” (this too is especially the case with mothers). Well, by some one of these marks people generally characterise Friendship: and each of these the good man has towards himself, and all others have them in so far as they suppose themselves to be good. (For, as has been said before, goodness, that is the good man, seems to be a measure to every one else.)
