Abstract
he paper examines the thesis that participants in shared intentional activities have first-person plural ‘practical knowledge’ of what they are jointly doing, in the sense of ‘practical knowledge’ articulated by G.E.M Anscombe. Who is supposed to be the subject of such knowledge? The group, or members of the group, or both? It is argued that progress with this issue requires conceiving of collective activities (of the kind affording ‘plural practical knowledge’)as instances, not of supra-personal agency, but of interpersonal agency; specifically: as involving communication. There is a sense, it is suggested, in which the basic form of plural practical knowledge is relational: ‘I am doing x with you.’
