 Aristotle does not raise questions about what it is to desire good for the sake of another person. He treats this as an easily understood phenomenon, and has no doubts about its existence. But it is also clear that he takes this motive to be compatible with a love of one’s own good and a desire for one’s own happiness. Someone who has practical wisdom will recognize that he needs friends and other resources in order to exercise his virtues over a long period of time. When he makes friends, and benefits friends he has made, he will be aware of the fact that such a relationship is good for him. And yet to have a friend is to want to benefit someone for that other person’s sake; it is not a merely self-interested strategy. Aristotle sees no difficulty here, and rightly so. For there is no reason why acts of friendship should not be undertaken partly for the good of one’s friend and partly for one’s own good. Acting for the sake of another does not in itself demand self-sacrifice. It requires caring about someone other than oneself, but does not demand some loss of care for oneself. For when we know how to benefit a friend for his sake, we exercise the ethical virtues, and this is precisely what our happiness consists in.
