Facts
Friendship is undoubtedly central to our lives in part because the special concern we have for our friends must have a place within a broader set of concerns, including moral concerns, and in part because our friends can help shape who we are as persons.Philosophers from the ancient Greeks on have traditionally distinguished three notions that can properly be called love: agape, eros, and philia.
Love or Friendship
For this reason, love and friendship often get lumped together as a single topic; nonetheless, there are significant differences between them. As understood here, love is an evaluative attitude directed at particular persons as such, an attitude which we might take towards someone whether or not that love is reciprocated and whether or not we have an established relationship with her.Friendship, by contrast, is essentially a kind of relationship grounded in a particular kind of special concern each has for the other as the person she is; and whereas we must make conceptual room for the idea of unrequited love, unrequited friendship is senseless. Consequently, accounts of friendship tend to understand it not merely as a case of reciprocal love of some form (together with mutual acknowledgment of this love), but as essentially involving significant interactions between the friends—as being in this sense a certain kind of relationship.
There is an apparent tension here between the idea that friendship essentially involves being concerned for your friend for his sake and the idea of pleasure and utility friendships: how can you be concerned for him for his sake if you do that only because of the pleasure or utility you get out of it? If you benefit your friend because, ultimately, of the benefits you receive, it would seem that you do not properly love your friend for his sake, and so your relationship is not fully one of friendship after all. So it looks like pleasure and utility friendships are at best deficient modes of friendship; by contrast, virtue friendships, because they are motivated by the excellences of your friend's character, are genuine, non-deficient friendships. For this reason, most contemporary accounts, by focusing their attention on the non-deficient forms of friendship, ignore pleasure and utility friendships.
