Other things being equal, the small man is more excitable and becomes angry more easily than the large man. He also cools down more quickly. When the huge bulk of the big man becomes thoroughly aroused, thoroughly wrought up, it is time to get out of the way and stand from under.
STRUCTURE
Hall Caine, the novelist, has an immense head, a slender jaw, and a small, fragile body. James J. Jeffries, the pugilist, has a comparatively small head, a large jaw, and huge bones and muscles. Ex-President Taft has a comparatively small head, round face, round body, round arms and legs. These are differences in structure.
Hall Caine is of the mental type. He is by nature unfitted to be either a pugilist, a hammer-thrower, an explorer, a banker, or a judge. He is, however, pre-eminently fitted to dream dreams of truth and beauty, to construct those dreams into stories and plays. James J. Jeffries is by nature and physique fitted for the trade of boiler-maker, for the sport of pugilism, and for physical and manual accomplishment in general. Ex-President Taft is by nature and physique fitted to sit quietly in a big chair and direct the work of others, to administer affairs, to sit upon the bench and weigh impartially causes of dispute between his fellow men. As you see, these three are our old friends, the physically frail, the man of bone and muscle, and the fat man.
The assignment of vocation according to structure is but common sense. The dreamer has too slender a body for manual labor and is both too nervous and too impatient of confinement to sit in an easy chair or on the bench. The big, corpulent man enjoys the good things of life. He is well nourished and free from anxiety. He is, therefore, especially well fitted to judge calmly, deliberately and impartially. The man of bone and muscle is too busy with his physical activities for dreams and too impatient of confinement to sit in an easy chair or on the bench.
TEXTURE
Men also differ from one another very markedly in texture. This is easily observable in the texture of hair, skin, features, general body build, hands and feet. According to Prof. Ernst Haeckel, the skin is the first and oldest sense organ. Indeed, all the other sense organs and the nervous system and brain which have evolved in the use of them, are simply inturned and specialized skin cells. This being true, the texture of the entire organism, and especially the brain and nervous system, is accurately indicated by the texture of the skin and its appendages, the hair and nails.
Even the most casual observer notes the differences between the man with coarse hair, coarse skin, rugged features,
large, loosely-built limbs, hands and feet, and the man with fine skin, silky hair, delicate, regular features, slender limbs, and finely moulded hands and feet. The individual of fine texture is sensitive and naturally refined. He loves beauty. He does his best work when he is creating something or handling something which is fine and beautiful. The coarse-textured individual is strong, vigorous, virile, and enduring. He can do hard, unpleasant work, can go through hardships, and can remain cheerful even in the midst of grimy, unpleasant and unlovely surroundings. For these reasons, fine-textured people do their best work in such lines as art, literature, music, jewelry, dry goods, millinery, and fine, delicate tools, machinery and materials; while we must rely upon coarse-textured people to do the heavy, hard, rough, pioneering and constructive work of the world. Even in art and literature coarse-textured people produce that which is either vigorous and virile or gruesome and horrible.
Because of their refined sensibilities, fine-textured people usually sympathize with the classes, the aristocracy; the coarse-textured people with the masses. It is a remarkable fact that practically all of our great liberators, radicals and revolutionists have been and are men of coarse texture. There is a great scientific truth underlying the saying amongst the people that certain ideas or books are "too fine-haired" for them.
