VII. Principles of Psychosomatic Physiology

It is otherwise when we seek to determine the somatic correlatives for feeling and willing. There we have first to blaze the requisite trail through the findings of current physiology. And once we have succeeded in doing so, we shall find that, just as representation is necessarily related to nervous activity, so feeling must be seen as related to that vital rhythm which is centred in, and connected with, the respiratory system; bearing in mind that, for this purpose, the rhythm of breathing must be traced right into the outermost peripheral regions of the organism. To arrive at concrete results here, the findings of physiological research need to be pursued in a direction which is as yet decidedly unfamiliar. If we take the trouble to do this, preliminary objections to bracketing feeling with respiration, all disappear, and what at first looks like an objection turns out to be a proof. Take one simple example from the wide range available: musical experience is dependent on some feeling, but the content of musical form subsists in representations furnished by auditory perception. How does musical emotion arise? The representation of the tonal shape (which depends on organ of hearing and neural process) is not yet the actual musical experience. That arises in the measure that the rhythm of breathing, continuing further into the brain, confronts within that organ the effects produced there by ear and nervous system. The psyche now lives, not alone in what is heard and represented, or thought, but in the breathing rhythm. Something is released in the breathing rhythm through the fact that neural process impinges on rhythmic life. Once we have seen the physiology of respiration in its true light, we are led on all hands to the conclusion that the psyche, in experiencing emotion, is supported by the rhythmic process of breathing, in the same way that, in representation and ideation, it is supported by neural processes. And it will be found that willing is supported, in the same way, by the physical processes of metabolism. Here again one must include the innumerable offshoots and ramifications of these processes, which extend throughout the entire organism.
