In the chapter on the glands of internal secretion as an interlocking directorate, certain generalities were stated as the laws of the government of the organism's life by them in association with the vegetative apparatus. It was put forward as a fundamental revision of the theory, hitherto accepted, of the limitation of mind to the brain cells. We think and feel not alone with the brain, but with our muscles, our viscera, our vegetative nerves, and last but not least our endocrine organs. In short, we think and feel with each and every part of ourselves. Among these pristine factors determining the content of consciousness, the endocrines are most important, because they alone to start with, of all the other factors, are different in each and every individual. They are what render him unique at birth, even though he looks the counterpart of millions of other babies born at the same time. They constitute his inner destiny. As he grows, the external factors, social experiences, climate, accidents, and disease modify and condition the reactions and complexity of the endocrine system. As these modifications and associations are of the greatest import for the final elaboration of the personality, composing as they do the elements of the unconscious which confers the unique stamp of normal, abnormal, supernormal, or subnormal, it is worth while now to review the most general of the determining laws. Man is an energy phenomenon, both conscious and unconscious, with the energy emanating from the endocrine-vegetative mechanisms. So it becomes possible for us, by their aid, to analyze the conscious, the subconscious and the unconscious with the terms long current in the analyses of physics. 1. Man is an energy machine which, though it is constantly losing energy as a whole; consists of parts constantly accumulating energy (as a result of inherent chemical reactions accelerated by the absorption of food). This process of local accumulation of energy associated with general loss of energy may be observed even in the ameba, in the form of stored reserve food material. Evolution created a system of organs, the viscera, as specialists in energy conservation, utilization or transformation.
