My living room chairs, like the table they surround are both made out of wood. While constructed of a similar material, they have different forms and different functions. One did not emerge from the other. And having sat there and eaten for many decades, incorporating organic material that was other and now is me, I am by no means descended from the myriad of plants and animals that I have consumed. The ultimate reality of a living being is its existence in itself as a participant in all existence. The structure of that being is wholistic, including simpler forms of being that we understand as matter. That structure is organized in accordance to the kind of being that it is, in our case human. That is the organizing principle that subsumes the psychological and physiological structures which may be separated but become one in the formation of the particular life form. The reality of who we are is known here and now, and it was created first in Adam, by the Spirit, which maintains us, and the wondrous earth from which all life springs.
