Our first object, then, should be to prevent a breach; our second, to secure that, if it does occur, our friendship should seem to have died a natural rather than a violent death. Next, we should take care that friendship is not converted into active hostility, from which flow personal quarrels, abusive language, and angry recriminations. These last, however, provided that they do not pass all reasonable limits of forbearance, we ought to put up with, and, in compliment to an old friendship, allow the party that inflicts the injury, not the one that submits to it, to be in the wrong. Generally speaking, there is but one way of securing and providing oneself against faults and inconveniences of this sort--not to be too hasty in bestowing our affection, and not to bestow it at all on unworthy objects. Now, by "worthy of friendship" I mean those who have in themselves the qualities which attract affection. This sort of man is rare; and indeed all excellent things are rare; and nothing in the world is so hard to find as a thing entirely and completely perfect of its kind. But most people not only recognize nothing as good in our life unless it is profitable, but look upon friends as so much stock, caring most for those by whom they hope to make most profit. Accordingly they never possess that most beautiful and most spontaneous friendship which must be sought solely for itself without any ulterior object. They fail also to learn from their own feelings the nature and the strength of friendship. For every one loves himself, not for any reward which such love may bring, but because he is dear to himself independently of anything else. But unless this feeling is transferred to another, what a real friend is will never be revealed; for he is, as it were, a second self. But if we find these two instincts shewing themselves in animals,--whether of the air or the sea or the land, whether wild or tame,--first, a love of self, which in fact is born in everything that lives alike; and, secondly, an eagerness to find and attach themselves to other creatures of their own kind; and if this natural action is accompanied by desire and by something resembling human love, how much more must this be the case in man by the law of his nature? For man not only loves himself, but seeks another whose spirit he may so blend with his own as almost to make one being of two.
