From the dawn of life, I need hardly say, all the instincts that have contributed to the preservation of offspring must have been favoured and cultivated by natural selection, and in many cases even in types of life very remote from Humanity, such instincts have prompted to very different actions from such as would flow from the mere instinct of self-preservation. If you thrust your walking-stick into an ant-heap, and watch the wild hurry and confusion that ensues when part of the interior is laid bare, you will see that all the workers are busy in moving the larvæ into places of safety. It is not exactly a maternal instinct, for the workers are not mothers, but it is an altruistic instinct involving acts of self-devotion. So in the case of fish that ascend rivers or bays at spawning time, the actions of the whole shoal are determined by a temporarily predominant instinct that tends towards an altruistic result. In these and lower grades of life there is already something at work besides the mere struggle for life between individuals; there is something more than mere contention and slaughter; there is the effort towards cherishing another life than one's own. In these regions of animate existence we catch glimpses of the cosmic roots of love and self-sacrifice. For the simplest and rudest productions of Nature mere egoism might suffice, but to the achievement of any higher aim some adumbration of altruism was indispensable. Before such divine things as love and self-sacrifice could spring up from their cosmic roots and put forth their efflorescence, it was necessary that conscious personal relations should become established between mother and infant. We have already observed the critical importance of these relations in the earliest stages of the evolution of human society. We may now add that the relation between mother and child must have furnished the first occasion for the sustained and regular development of the altruistic feelings. The capacity for unselfish devotion called forth in that relation could afterward be utilized in the conduct of individuals not thus related to one another. Of all kinds of altruism the mother's was no doubt the earliest; it was the derivative source from which all other kinds were by slow degrees developed. In the evolution of these altruistic feelings, therefore,--feelings which are an absolutely indispensable constituent in the process of ethical development,--the first appearance of real maternity was an epoch of most profound interest and importance in the history of life upon the earth.
