Now there is no need, and should be no desire, to evade the biologic necessity implied by marriage. Children must be brought into the world and reared if life is to go on. All the why-fors of this are given in a thousand biologic and anthropologic volumes, and so no need to discuss them here. But this much may be said, that among animals the limits of the control of the maternal feeling or instinct are rigidly confined to simple necessity. Love seems to disappear as soon as the young can possibly walk or fly and get their food--proof of its mechanistic or chemic quality and origin and its lack of any sacrosanct and “for eternity” spiritual character. Indeed, under most phases of animal life the father is absolutely indifferent to the fate of his offspring. In many, perhaps most, animals he seems to care no more for his children than if they were moving bushes. Certainly he cares no more for his own than for those of another, and the idea of any love toward grandchildren is absurd. Not even the mother shows this. But it is of the greatest interest to note that with the appearance of humanity and its ideas of home and property (both products of maternal instinct or the chemic necessity in her for the care of her young) there has arisen a natural extension of the scope and control of the family instinct, so that the interest of the parents continues into or through adult life. Support and protection of the mother continues beyond the child-bearing period, grandchildren are beloved, more distant relatives are held within the family affection, and the patriarchal type of society is established. Since the higher ideals of society and civilization have been permitted to arise the ægis of love has extended over the nation, and patriotism, with its great influence in war and history, has appeared. Finally that highest development of humanity, ethics or love of humanity, has arisen (still an actual outgrowth and extension of maternal instinct or love apparently), as well as the theory of the existence of a Divine Father-Mother of humanity and of all life.
