Abstract
An unrestricted conception of actors and their interdependence in action has now been deployed effectively in various fields of study, but the question remains how we can discriminate reasonably in our action sharing if there is more to consider than simply putting persons ahead of things. By what general practical realizations can a universal action sharer be guided? I identify four primary levels of action sharing—-coexistence, cooperation, collaboration, and communion—-showing a distinctive complex of factual and directive considerations in each. I further show how three orientations in which we approach fellow actors—-need, desire, and delight—-sustain different, partly divergent and partly complementary understandings of action sharing. This analysis helps us to anticipate the character of the strongest appeal that can be made for consideration of a fellow actor.
