Group agents are able to act but are not literally agents. Some group agents, e.g., we-mode groups and corporations, can, however, be regarded as functional group agents that do not have “intrinsic” mental states and phenomenal features comparable to what their individual members on biological and psychological grounds have. But they can have “extrinsic” mental states, states collectively attributed to them—primarily by their members. In this paper, we discuss the responsibility of such group agents. We defend the view that if the group members have accepted the group agent’s attitudes and are committed to them, we can favorably compare the situation with the case of individual human agents and a group agent can be regarded as morally responsible for its intentional activities.

In this paper a social group’s (retrospective) responsibility for its actions and their consequences are investigated from a philosophical point of view. Building on Tuomela’s theory of group action, the paper argues that group responsibility can be analyzed in terms of what its members (jointly) think and do qua group members. When a group is held responsible for some action, its members, acting qua members of the group, can collectively be regarded as praiseworthy or blameworthy, in the light of some normative standard, for what the group has done. The paper gives a necessary and sufficient conditions analysis of a group’s responsibility for its actions and their outcomes, and the conditions can be cashed out in terms of the group members’ joint (and other) actions.

The paper argues that there are two main kinds of joint action, direct joint bringing about (or performing) something (expressed in terms of a DO-operator) and jointly seeing to it that something is the case (expressed in terms of a Stit-operator). The former kind of joint action contains conjunctive, disjunctive and sequential action and its central subkinds. While joint seeing to it that something is the case is argued to be necessarily intentional, direct joint performance can also be nonintentional. Actions performed by social groups are analyzed in terms of the notions of joint action (basically DO and Stit).A precise semantical analysis of the aforementioned kinds of joint action is given in terms of time-trees. With each participant a tree is connected, and the trees are joined defining joint possible worlds in terms of state-expressing nodes from the trees. Sentences containing DO and Stit are semantically evaluated with respect to such joint possible worlds. Intentional joint actions are characterized in terms of the notion of we-intention (joint intention), characterized formally by means of a special operator.

This work provides a rigorous analysis of what Tuomela calls ‘the we-perspective’. Tuomela's overarching project is to argue that ‘conceptualizing social life and theorizing about it requires the use of group concepts, indeed the we-perspective and, especially, the we-mode.’ Already some of the complexities of Tuomela's approach will be evident – viz. in the distinction, implied in the above quotation and carried through systematically throughout the work, between the ‘we-perspective’ and the ‘we-mode’. For, indeed, it is possible, on his account, to take up the we-perspective from the I-mode and, indeed, this is probably quite common, but is not adequate to ground the analysis of social and institutional concepts. As Tuomela puts it, ‘The concept of social institution is a we-mode concept, and in actual practice, at least some we-mode thinking and acting is required for institutions to function adequately.’ Since ‘we-mode’ is the more central notion, let us begin with that. It will be instructive to quote Tuomela at length : " Agent A, a member of group g, has ATT, the attitude ATT with content p, in … "
