Abstract
Cooperation has been analyzed primarily in the context of theories of collective intentionality. These
discussions have primarily focused on interactions between pairs or small groups of agents who know one
another personally. Cooperative game theory has also been used to argue for a form of cooperation in large
unorganized groups. Here I consider a form of minimal cooperation that can arise among members of
potentially large organized groups (e.g., corporate teams, committees, governmental bodies). I argue that
members of organized groups can be minimally cooperative in virtue of playing roles in an organizational
structure and having a common goal. The minimal form of cooperation I argue for is not grounded in
collective intentions involving symmetric mental states, special collective intentional modes, or joint
commitments. More generally, I show how considering minimal cooperation in the context of organized
groups provides an opportunity to reevaluate the extent to which the social world and social phenomena
depend on internalist mental factors (e.g., intentions, beliefs) and externalist non-mental factors (e.g.,
documents, laws, job descriptions). The view of minimal cooperation among members of organized groups I
offer provides support for an externalist rather than internalist theory of at least one social phenomenon.
