INTRODUCTION

It is common to regard love, friendship, and other associational ties to others as an important part of a happy or flourishing life. This would be easy enough to understand if we focused on friendships based on pleasure, or associations, such as business partnerships, predicated on mutual advantage. For then we could understand in a straightforward way how these interpersonal relationships would be valuable for someone involved in such relationships just insofar as they caused her pleasure or causally promoted her own independent interests. But many who regard love, friendship, and other associational ties as an important part of a happy or flourishing life suppose that in many sorts of associations— especially intimate associations—the proper attitude among associates is concern for the other for the other's own sake, not just for the pleasure or benefits one can extract from one's associates. It is fairly clear how having friends of this sort is beneficial. What is less clear is how being a friend of this sort might contribute to one's own happiness or well-being. Even if we can explain this, it looks as if the contribution that friendship makes to one's happiness could not be the reason one has to care for friends, for that would seem to make one's concern for others instrumental, not a concern for the other for her own sake.
