Abstract

The paper gives a conceptual clarification of what the notion of a part of a joint action (project, etc;) involves. The - mutually recognized - division of a joint action into parts can be based on social norms (viz. formal or informal rules, or proper social norms such as conventions or group specific social norms) or it can be based on agreement, coercion, or some analogous social mechanism. The paper also discusses the notions of a we-intention, of the intention to perform an action as one’s part of a joint action, and of an agent’s intentionally performing an action as his part of a joint action.
