  Roth [2004] takes seriously the mutual obligations identified by Gilbert, and offers an account that, while non-reductive, nevertheless invokes a conception of intention and commitment that in some respects is friendlier to that invoked by Bratman. It is not entirely clear whether, in positing primitive joint commitments, Gilbert means to commit herself to the ontological thesis that there exist group agents over and above the constituent individual agents. Pettit [2003] defends just such a thesis. He argues that rational group action often involves the “collectivizing of reason,” with participants acting in ways that are not rationally recommended from the participant's individual point of view. The resulting discontinuity between individual and collective perspectives suggests, on his view, that groups can be rational, intentional agents distinct from their members.
