The fluid metabolism ends in the bladder. It absorbs, concentrates, and discharges into the outer world what the kidney, in its perception of the soul-permeated fluid organism, releases from the interior as unusable. The activity of kidney and bladder stands in a striking relationship to its counter-pole: the outwardly directed nerve-sense activity. This holds above all for the eye, and in the stag for the antlers, which after dying off remain for some months until shedding as a kind of groping sense organ. The eye, in its structure governed almost entirely by the laws of physics, appears like a piece of the outer world that sinks "gulf-like" into the organism. The antlers grow as limb-bones beyond the head and die away, quite literally, into an object of the outer world.
