Mother love is not a human invention. It has been inherited. It is older than the Rocky Mountains. Mother love in man came from the same source as the backbone in man from pre-human forms.

When a monkey child dies, the mother carries the little corpse around with her for clays, refuses to eat, and sits often in silence and grief. Mother birds will risk their very lives for their young. So will mother bears, and lions, and whales, and the females of many other species.

Is it any wonder, therefore, that the young, accustomed to such an environment, grow up to consider life itself a game, in which they are to strive to outwit those about them? Is it any wonder that you and I and men and women everywhere are helplessly selfish, when we were born so, when all that we know of altruism has come thru Sunday-school rumors and straggling precepts, and when we have all our lives been surrounded by selfish people and occupied in selfish pastimes and professions? Nothing could be more natural. Altruism is anomalous on the earth, and it is not astonishing.

It is one of degree, not of kind. The philosopher, the clodhopper, and the ape, all use precisely the same methods of reasoning, differing only in exactness and in the materials of consciousness dealt with.
