Abstract

In this paper we will study two central social notions, acting as a group member and collective commitment. Our study of the first of these notions is – as far as we know – the first systematic work on the topic. Acting as a group member is a central notion that obviously must be understood when speaking of the “we-perspective”, group life, and of social life more generally. Thus, not only philosophy of sociality, philosophy of social science, political and moral philosophy but also the various social sciences need this notion and should benefit from our analyses and arguments.Collective commitment is the other “we-perspective” notion studied in our paper. We have argued for its importance as representing a kind of social glue needed for group members when thinking and acting as a group. In contrast to some other studies (e.g. Gilbert, 1989, 2000, Castelfranchi, 1995) our most elementary notion of collective commitment is not intrinsically normative but is only instrumentally “normative” and intention-relative. Thus our treatment covers more ground than the previous accounts do.
