¶ 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 ¶ _Human Analysis differs from every other system of character analysis in that it classifies man, for the first time, into five types according to his biological evolution._ ¶ 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! Preferences Inborn ¶ 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. Follow Our Bents ¶ In other words, more than ninety-nine per cent of all the people you know are following their natural bents in reacting to all their experiences--from the most trivial incidents to the most far-reaching emergencies. "Took It" From Grandmother ¶ The individual is seldom conscious of these habitual acts of his, much less of where he got them. The nearest he comes is to say he "got it from his father" or "she takes it from grandmother." But where did grandmother get it? Man No Mystery
