This inherent potentiality for altering the organism to meet the demands of the environment is especially noticeable in races and is the reason for most racial differences.
Differences in environment—climate, altitude and topography necessitated most of these physical differentiations which today enable us to know at a glance whether a man belongs to the white race, the yellow race, or the black race. The results of these differentiations and modifications will be told in the various chapters of this book.
Types Earlier than Races
The student of Human Analysis reads the disposition and nature of every individual with ease regardless of whether that individual be an American, a Frenchman, a Kaffir or a Chinaman, because Human Analysis explains those fundamental traits which run through every race, color and nationality, according to the externals which always go with those traits.
Five Biological Types
It deals with man in the light of the most recent scientific discoveries. It estimates each individual according to his “human” qualities rather than his “character” or so-called “moral” qualities. In other words, it takes his measure as a human being and determines from his externals his chances for success in the world of today.
These Rules Work
Every rule in this book is based on scientific data, has been proved to be accurate by investigations and surveys of all kinds of people in all parts of the world.
These rules do not work merely part of the time. They work all the time, under all conditions and apply to every individual of every race, every color, every country, every community and every family.
Through this latest human science you can learn to read people as easily as you read books—if you will take the little time and pains to learn the rules which compose your working alphabet.
Do What We Want to Do
It is easy to know what an individual will do under most circumstances because every human being does what he wants to do in the way he prefers to do it most of the time. If you doubt it try this test: bring to mind any intimate friends, or even that husband or wife, and note how few changes they have made in their way of doing things in twenty years!
Every human being is born with preferences and predilections which manifest themselves from earliest childhood to death. These inborn tendencies are never obliterated and seldom controlled to any great extent, and then only by individuals who have learned the power of the mind over the body. Inasmuch as this knowledge is possessed by only a few, most of the people of the earth are blindly following the dictates of their inborn leanings.
