But, quite apart from the person who wields power and knows how to concentrate so much in his two hands, the relation of each and every man to his own excrement belongs to the sphere of power. Nothing has been so much part of one as that which turns into excrement. The constant pressure which, during the whole of its long process through the body, is applied to the prey which has become food; its dissolution and intimate union with the creature digesting it; the complete and ifnal annihilation, first of all functions and then of everything which once constituted its individuality; its assimilation to something alredy existing, that is, to the body of the eater—all this may very well be seen as the central, if most hidden, process of power.
