ach 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.

For intercommunication and interaction between the viscera two systems
were elaborated: a younger system of direct contacts, the nerves,
and nerve cells, through which influences could be conducted for the
stimulation, acceleration, retardation or inhibition of an energy
process in them; and the older, the endocrine gland association, for
the production of chemical substances to act as messengers to be sent
from one viscus to another, and also to the nerves, through the blood
or lymph which bathe all the cells. They could affect only one or
certain organs, because by selection only the chosen organ or organs
knew the code, as it were. The chemical system is much the older
system, and preceded the nerve system by aeons of time. The whole
system, viscera, visceral nerves and the endocrines gradually united
into a complete autonomous organism within the organism, and as such
functions as the vegetative apparatus.
