 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.
