Friendship essentially involves a distinctive kind of concern for your friend, a concern which might reasonably be understood as a kind of love. Philosophers from the ancient Greeks on have traditionally distinguished three notions that can properly be called love: agape, eros, and philia. Agape is a kind of love that does not respond to the antecedent value of its object but instead is thought to create value in the beloved; it has come through the Christian tradition to mean the sort of love God has for us persons as well as, by extension, our love for God and our love for humankind in general. By contrast, eros and philia are generally understood to be responsive to the merits of their objects—to the beloved's properties, especially his goodness or beauty. The difference is that eros is a kind of passionate desire for an object, typically sexual in nature, whereas ‘philia’ originally meant a kind of affectionate regard or friendly feeling towards not just one's friends but also possibly towards family members, business partners, and one's country at large (Liddell et al., 1940; Cooper, 1977a). Given this classification of kinds of love, philia seems to be that which is most clearly relevant to friendship (though just what philia amounts to needs to be clarified in more detail).
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.
Nonetheless, questions can be raised about precisely how to distinguish romantic relationships, grounded in eros, from relationships of friendship, grounded in philia, insofar as each involves significant interactions between the involved parties that stem from a kind of reciprocal love that is responsive to merit. Clearly the two differ insofar as romantic love normally has a kind of sexual involvement that friendship lacks; yet, as Thomas (1989) asks, is that enough to explain the real differences between them? Badhwar (2003, 65–66) seems to think so, claiming that the sexual involvement enters into romantic love in part through a passion and yearning for physical union, whereas friendship involves instead a desire for a more psychological identification. Yet it is not clear exactly how to understand this: precisely what kind of “psychological identification” or intimacy is characteristic of friendship? (For further discussion, see Section 1.2.)
In philosophical discussions of friendship, it is common to follow Aristotle (Nicomachean Ethics, Book VIII) in distinguishing three kinds of friendship: friendships of pleasure, of utility, and of virtue. Although it is a bit unclear how to understand these distinctions, the basic idea seems to be that pleasure, utility, and virtue are the reasons we have in these various kinds of relationships for loving our friend. That is, I may love my friend because of the pleasure I get out of her, or because of the ways in which she is useful to me, or because I find her to have a virtuous character. Given the involvement of love in each case, all three kinds of friendship seem to involve a concern for your friend for his sake and not for your own.
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.
As mentioned in the first paragraph of this section, philia seems to be the kind of concern for other persons that is most relevant to friendship, and the word, ‘philia,’ sometimes gets translated as friendship; yet philia is in some ways importantly different from what we ordinarily think of as friendship. Thus, ‘philia’ extends not just to friends but also to family members, business associates, and one's country at large. Contemporary accounts of friendship differ on whether family members, in particular one's children before they become adults, can be friends. Most philosophers think not, understanding friendship to be essentially a relationship among equals; yet some philosophers (such as Friedman 1989; Rorty 1986/1993; Badhwar 1987) explicitly intend their accounts of friendship to include parent-child relationships, perhaps through the influence of the historical notion of philia. Nonetheless, there do seem to be significant differences between, on the one hand, parental love and the relationships it generates and, on the other hand, the love of one's friends and the relationships it generates; the focus here will be on friendship more narrowly construed.
In philosophical accounts of friendship, several themes recur consistently, although various accounts differ in precisely how they spell these out. These themes are: mutual caring (or love), intimacy, and shared activity; these will be considered in turn.
1.1 Mutual Caring
A necessary condition of friendship, according to just about every view (Telfer 1970–71, Annas 1988; Annas 1977, Annis 1987, Badhwar 1987, Millgram 1987, Sherman 1987, Thomas 1989; Thomas 1993; Thomas 1987, Friedman 1993; Friedman 1989, Whiting 1991, Hoffman 1997, Cocking & Kennett 1998, and White 1999a; White 1999b; White 2001) is that the friends each care about the other, and do so for her sake; in effect, this is to say that the friends must each love the other. Although many accounts of friendship do not analyze such mutual caring any further, among those that do there is considerable variability as to how we should understand the kind of caring involved in friendship. Nonetheless, there is widespread agreement that caring about someone for his sake involves both sympathy and action on the friend's behalf. That is, friends must be moved by what happens to their friends to feel the appropriate emotions: joy in their friends’ successes, frustration and disappointment in their friends’ failures (as opposed to disappointment in the friends themselves), etc. Moreover, in part as an expression of their caring for each other, friends must normally be disposed to promote the other's good for her sake and not out of any ulterior motive. (However, see Velleman 1999 for a dissenting view.)
To care about something is generally to find it worthwhile or valuable in some way; caring about one's friend is no exception. A central difference among the various accounts of mutual caring is the way in which these accounts understand the kind of evaluation implicit therein. Most accounts understand that evaluation to be a matter of appraisal: we care about our friends at least in part because of the good qualities of their characters that we discover them to have (Annas 1977; Sherman 1987; Whiting 1991); this is in line with the understanding of love as philia or eros given in the first paragraph of Section 1 above. Other accounts, however, understand caring as in part a matter of bestowing value on your beloved: in caring about a friend, we thereby project a kind of intrinsic value onto him; this is in line with the understanding of love as agape given above.
Friedman (1989, 6) argues for bestowal, saying that if we were to base our friendship on positive appraisals of our friend's excellences, “to that extent our commitment to that person is subordinate to our commitment to the relevant [evaluative] standards and is not intrinsically a commitment to that person.” However, this is too quick, for to appeal to an appraisal of the good qualities of your friend's character in order to justify your friendship is not on its own to subordinate your friendship to that appraisal. Rather, through the friendship, and through changes in your friend over time, you may come to change your evaluative outlook, thereby in effect subordinating your commitment to certain values to your commitment to your friend. Of course, within friendship the influence need not go only one direction: friends influence each other's conceptions of value and how to live. Indeed, that friends have a reciprocal effect on each other is a part of the concern for equality many find essential to friendship, and it is central to the discussion of intimacy in Section 1.2.
1.2 Shared Activity
A final common thread in philosophical accounts of friendship is shared activity. The background intuition is this: never to share activity with someone and in this way to interact with him is not to have the kind of relationship with him that could be called friendship, even if you each care for the other for his sake. Rather, friends engage in joint pursuits, in part motivated by the friendship itself. These joint pursuits can include not only such things as making something together, playing together, and talking together, but also pursuits that essentially involve shared experiences, such as going to the opera together. Yet for these pursuits to be properly shared in the relevant sense of “share,” they cannot involve activities motivated simply by self interest: by, for example, the thought that I’ll help you build your fence today if you later help me paint my house. Rather, the activity must be pursued in part for the purpose of doing it together with my friend, and this is the point of saying that the shared activity must be motivated, at least in part, by the friendship itself.
This raises the following questions: in what sense can such activity be said to be “shared,” and what is it about friendship that makes shared activity so central to it? The common answer to this second question (which helps pin down an answer to the first) is that shared activity is important because friends normally have shared interests as a part of the intimacy that is characteristic of friendship as such, and the “shared” pursuit of such shared interests is therefore an important part of friendship. Consequently, the account of shared activity within a particular theory ought to depend at least in part on that theory's understanding of the kind of intimacy relevant to friendship. And this generally seems to be the case: for example, Thomas (1987, 1989, 1993), who argues for a weak conception of intimacy in terms of mutual self-disclosure, has little place for shared activity in his account of friendship, whereas Sherman (1987), who argues for a strong conception of intimacy in terms of shared values, deliberation, and thought, provides within friendship a central place not just to isolated shared activities but, more significantly, to a shared life.
Nonetheless, within the literature on friendship the notion of shared or joint activity is taken for granted: not much thought has been given to articulating clearly the sense in which friends share their activity. This is surprising and unfortunate, especially insofar as the understanding of the sense in which such activities are “shared” is closely related to the understanding of intimacy that is so central to any account of friendship; indeed, a clear account of the sort of shared activity characteristic of friendship may in turn shed light on the sort of intimacy it involves. This means in part that a particular theory of friendship might be criticized in terms of the way in which its account of the intimacy of friendship yields a poor account of the sense in which activity is shared. For example, one might think that we must distinguish between activity we engage in together in part out of my concern for someone I love, and activity we share insofar as we engage in it at least partly for the sake of sharing it; only the latter, it might be argued, is the sort of shared activity constitutive of the relationship of friendship as opposed to that constitutive merely of my concern for him (see Nozick 1989). Consequently, according to this line of thought, any account of the intimacy of friendship that fails to understand the sharing of interests in such a way as to make sense of this distinction ought to be rejected.
Helm (2008) develops an account of shared activity and shared valuing at least partly with an eye to understanding friendship. He argues that the sense in which friends share activity is not the sort of shared intention and plural subjecthood discussed in literature on shared intention within social philosophy (on which, see Tuomela 1995, 2007; Gilbert 1996, 2000, 2006; Searle 1990; and Bratman 1999), for such sharing of intentions does not involve the requisite intimacy of friendship. Rather, the intimacy of friendship should be understood partly in terms of the friends forming a “plural agent”: a group of people who have joint cares—a joint evaluative perspective—which he analyzes primarily in terms of a pattern of interpersonally connected emotions, desires, judgments, and (shared) actions. Friendships emerge, Helm claims, when the friends form a plural agent that cares positively about their relationship, and the variety of kinds of friendships there can be, including friendships of pleasure, utility, and virtue, are to be understood in terms of the particular way in which they jointly understand their relationship to be something they care about—as tennis buddies or as life partners, for example.
1.3 Shared Activity
A final common thread in philosophical accounts of friendship is shared activity. The background intuition is this: never to share activity with someone and in this way to interact with him is not to have the kind of relationship with him that could be called friendship, even if you each care for the other for his sake.
