VII. Principles of Psychosomatic Physiology

The fact remains that unprejudiced contemplation of the psyche obliges us to recognise the existential independence of the will, and accurate insight into the findings of physiology compels the conclusion that the will, as such, must be linked not with neural but with metabolic processes. If a man wants to form clear concepts in this field, then he must look at the findings of physiology and psychology in the light of the facts themselves and not, as so often happens in the present day practice of those sciences, in the light of preconceived opinions and definitions—not to mention theoretical sympathies and antipathies.[^1]
