It should be clear to anyone accustomed to the working of biological laws that all the tendencies of a living organism are progressive in their development, and are held in check by the interaction of their several forces. Each living form, with its dominant characteristics, represents a balance of power, a sort of compromise. The size of earth’s primeval monsters was limited by the tensile strength of their material. Sea monsters can be bigger, because the medium in which they move offers more support. Birds must be smaller for the opposite reason. The cow requires many stomachs of a liberal size, because her food is of low nutritive value; and she must eat large quantities to keep her machine going. The size of arboreal animals, such as monkeys or squirrels, is limited by the nature of their habitat: creatures that live in trees cannot be so big as creatures that live on the ground. Every quality of every creature is relative to its condition, and tends to increase or decrease accordingly; and each quality tends to increase in proportion to its use, and to decrease in proportion to its disuse. Primitive man and his female were animals, like other animals. They were strong, fierce, lively beasts; and she was as nimble and ferocious as he, save for the added belligerence of the males in their sex-competition. In this competition, he, like the other male creatures, fought savagely with his hairy rivals; and she, like the other female creatures, complacently viewed their struggles, and mated with the victor. At other times she ran about in the forest, and helped herself to what there was to eat as freely as he did.
There seems to have come a time when it occurred to the dawning intelligence of this amiable savage that it was cheaper and easier to fight a little female, and have it done with, than to fight a big male every time. So he instituted the custom of enslaving the female; and she, losing freedom, could no longer get her own food nor that of her young. The mother ape, with her maternal function well fulfilled, flees leaping through the forest—plucks her fruit and nuts, keeps up with the movement of the tribe, her young one on her back or held in one strong arm. But the mother woman, enslaved, could not do this. Then man, the father, found that slavery had its obligations: he must care for what he forbade to care for itself, else it died on his hands. So he slowly and reluctantly shouldered the duties of his new position. He began to feed her, and not only that, but to express in his own person the thwarted uses of maternity: he had to feed the children, too. It seems a simple arrangement. When we have thought of it at all, we have thought of it with admiration. The naturalist defends it on the ground of advantage to the species through the freeing of the mother from all other cares and confining her unreservedly to the duties of maternity. The poet and novelist, the painter and sculptor, the priest and teacher, have all extolled this lovely relation. It remains for the sociologist, from a biological point of view, to note its effects on the constitution of the human race, both in the individual and in society.
When man began to feed and defend woman, she ceased proportionately to feed and defend herself. When he stood between her and her physical environment, she ceased proportionately to feel the influence of that environment and respond to it. When he became her immediate and all-important environment, she began proportionately to respond to this new influence and to be modified accordingly. In a free state, speed was of as great advantage to the female as to the male, both in enabling her to catch prey and in preventing her from being caught by enemies; but, in her new condition, speed was a disadvantage. She was not allowed to do the catching, and it profited her to be caught by her new master. Free creatures, getting their own food and maintaining their own lives, develop an active capacity for attaining their ends. Parasitic creatures, whose living is obtained by the exertions of others, develop powers of absorption and of tenacity—the powers by which they profit most. The human female was cut off from the direct action of natural selection, that mighty force which heretofore had acted on male and female alike with inexorable and beneficial effect, developing strength, developing skill, developing endurance, developing courage—in a word, developing species. She now met the influence of natural selection acting indirectly through the male, and developing, of course, the faculties required to secure and obtain a hold on him. Needless to state that these faculties were those of sex-attraction, the one power that has made him cheerfully maintain, in what luxury he could, the being in whom he delighted. For many, many centuries she had no other hold, no other assurance of being fed. The young girl had a prospective value, and was maintained for what should
