How to analyze people on sight through the science of human analysis the five human types

Significance of Size, Shape and Structure All dogs belong to the same species but there is a great difference between the "nature" of a St. Bernard and that of a terrier, just as there is a decided difference between the natures of different human beings. But in both instances the actions, reactions and habits of each can be accurately anticipated on sight by the shape, size and structure of the two creatures. Differences in Breed When a terrier comes into the room you instinctively draw away unless you want to be jumped at and greeted effusively. But you make no such movement to protect yourself from a St. Bernard because you read, on sight, the different natures of these two from their external appearance. You know a rose, a violet, a sunflower and an orchid and what perfume you are sure to find in each, by the same method. All are flowers and all belong to the same species, just as all human beings belong to the same 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.
