The phenomenology of joint agency: the implicit structures of the shared life-world

We do lots of things together in a shared manner. From the phenomenological point of view, does joint or shared agency need a conscious sense of shared agency? Yet there are many processes where we seem to just go along with the group without conscious intent. Building on the classic phenomenological accounts of Edmund Husserl, Alfred Schutz, Martin Heidegger (and the synthetic account of Berger & Luckmann), I want to emphasize the thick horizon of the life-world as a fundamental condition for intentional shared agency. Joint agency has divergent forms with their own peculiar intentionality, attentivity, anticipations and expectations, and embeddedness in a pre-predicative tacit knowledge in the overall live-world. Phenomenology recognizes that even ego-centered activities that appear to be fully 'agential' can be carried out in an anonymous un-owned manner, in the manner which Heidegger calls 'das Man', or 'the one'. This suggests that tacit belonging to the collective 'we' undergirds individual agency. Husserl, Heidegger, and Schutz all have accounts of this 'anonymous', pre-predicative kind of group participation. Phenomenology has rich accounts of anonymous, voluntary, shared, social participation that demand a new concept of agency, one neglected in the current literature in philosophy of action.
