 In an influential series of papers, Bratman has developed a reductive account of shared activity and shared  intention.[14]  He understands a shared intention to be an interpersonal structure of related intentions that serves to coordinate action and planning, as well as structure bargaining between  participants.[15]  The individually held intentions that constitute this structure—what we’ve been calling participatory intentions—are instances of a familiar sort of individual intention that figures in the planning and the coordination of one’s activities over time. When these individual intentions concern something that is done by more than one person, taking the form I intend that we J, they accord with Bratman’s version of the Intention Thesis, and the core of his proposals about shared intention and action. But Bratman imposes further conditions, and these serve to relate these participatory intentions in distinctive ways.
