Shared agency is a distinctive kind of sociality that involves interdependent planning, practical reasoning, and action between participants. Philosophical reflection suggests that agents engage in this form of sociality when a special structure of interrelated psychological attitudes exists between them, a set of attitudes that constitutes a collective intention. I defend a new way to understand collective intention as a combination of individual conditional intentions. Revising an initial statement of the conditional intention account in response to several challenges leads to (...) a specification of the properties these intentions need to have in order to be genuine commitments. I then show how a structure of conditional intentions with these properties settles a collection of agents on engaging in social interactions that display all the features typically associated with shared agency.

This entry surveys main accounts of collective intentions.

Pure quality of will theories claim that ‘the ultimate object’ of our responsibility responses (i.e., praise and blame) is the quality of our will. Any such theory is false—or so I argue. There is a second dimension of (moral) responsibility, independent of quality of will, that our responsibility responses track and take as their object—namely, how adroitly we are able to translate our will into action; I call this competence of will. I offer a conjectural explanation of the two dimensions (...) of (moral) responsibility: it matters to us that people actually perform adequately well because of how much it matters to us that we are able to live and work together successfully.
