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.
