VII. Principles of Psychosomatic Physiology
When something is “represented”, a neural process takes place, on the basis of which the psyche becomes conscious of its representation; when something is “felt”, a modification is effected in the breathing rhythm, through which a feeling comes to life; and in the same way, when something is “willed”, a metabolic process occurs that is the somatic foundation for what the psyche experiences as willing. It should be noted however that it is only in the first case (representation mediated by the nervous system) that the experience is a fully conscious, waking experience. What is mediated through the breathing-rhythm (including in this category everything in the nature of feelings, affects, passions and the like) subsists in normal consciousness with the force only of representations that are dreamed. Willing, with its metabolic succedaneum, is experienced in turn only with that third degree of consciousness, totally dulled, which also persists in sleep. If we look more closely at this series, we shall notice that the experience of willing is in fact wholly different from the experience of representation or ideation. The latter is something like looking at a coloured surface: whereas willing is like looking at a black area in the middle of a coloured field. We see nothing there in the uncoloured part of the surface precisely because—unlike the surrounding part, from which colour impressions are received—no such impressions are at hand from it. We “have the idea” of willing, because within the psyche’s field of ideational experience a patch of non-ideation inserts itself, very much as the interruptions of consciousness brought about by sleep insert themselves into the continuum of conscious life. It is to these differing types of conscious apprehension that the soul owes the manifold variety of its experience in ideation, feeling and willing.
