species. But their respective size, shape and structure tell you in
advance and on sight what their respective characteristics are.

The same is true of all human beings. They differ in certain
fundamentals but always and invariably in accordance with their
differences in size, shape and structure.

The Instinct of Self-Preservation

The reason for this is plain. Goaded by the instinct of
self-preservation, man, like all other living things, has made heroic
efforts to meet the demands of his environment. He has been more
successful than any other creature and is, as a result, the most complex
organism on the earth. But his most baffling complexities resolve
themselves into comparatively simple terms once it is recognized that
each internal change brought about by his environment brought with it
the corresponding external mechanism without which he could not have
survived.

Interrelation of Body and Brain

So today we see man a highly evolved creature who not only acts but
thinks and feels. All these thoughts, feelings and emotions are
interrelated.

The body and the mind of man are so closely bound together that whatever
affects one affects the other. An instantaneous change of mind instantly
changes the muscles of the face. A violent thought instantly brings
violent bodily movements.

Movies and Face Muscles

The moving picture industry--said to be the third largest in the
world--is based largely on this interrelation. This industry would
become extinct if something were to happen to sever the connection
between external expressions and the internal nature of men and women.

Tells Fundamentals

How much do external characteristics tell about a man? They tell, with
amazing accuracy, all the basic, fundamental principal traits of his
nature. The size, shape and structure of a man's body tell more
important facts about his real self--what he thinks and what he
does--than the average mother ever knows about her own child.

Learning to Read

If this sounds impossible, if the seeming incongruity, multiplicity
and heterogeneity of human qualities have baffled you, remember that
this is exactly how the print in all books and newspapers baffled you
before you learned to read.

Not long ago I was reading stories aloud to a three-year old. She wanted
to "see the pictures," and when told there were none had to be shown the
book.

"What funny little marks!" she cried, pointing to the print. "How do you
