Participation is not only a mental or intellectual event, but physical as well, nourished from human warmth. As such exchange intensifies – and wears thin, becomes sharper, gets layered – the interaction gets more and more stimulating and its outcomes can’t be foreseen anymore, because they depend on the interlocutors, who always vary, thus making the process-project they’re taking part in unique each time. That’s why there’s no recipe for participation. As participants and the reasons for which they met change, so does participation: we have to invent and experiment with it, everytime anew.
