What does a plant wish to accomplish, what does a body wish to accomplish, what does one wish to accomplish?
It is possible here to extrapolate upon Plato's strange phrase about "carving nature at its joints." It seems as though life differentiates itself into disparate bodies with their own boundaries, properties, and ultimately interests, and the bodies themselves are further differentiated into regions or sections which cohere together via various binding materials.
Aggregates form out of these interests exerting claims on one another, regulating each other through their own mutual actions on each other, actions which go towards maintaining some common body or vessel which is to sustain them.
Certain bodies also eventually evolve so as to regulate themselves.
But it seems as though when organizing communal production to make food and other supplies, it is useful to concentrate on general flourishing. What does everything want to do, and how does it all help itself in a system achieve this to the greatest extent possible? A system which is of course not closed, but which is interacting with countless others throughout space and time.
