The Origins of Society and of Morality.
One further point must be considered before this outline sketch of the manner of man’s origin can be called complete. The psychical development of Humanity, since its earlier stages, has been largely clue to the reaction of individuals upon one another in those various relations which we characterize as social.[10] In considering the origin of Man, the origin of human society cannot be passed over. Foreshadowings of social relations occur in the animal world, not only in the line of our own vertebrate ancestry, but in certain orders of insects which stand quite remote from that line. Many of the higher mammals are gregarious, and this is especially true of that whole order of primates to which we belong. Rudimentary moral sentiments are also clearly discernible in the highest members of various mammalian orders, and in all but the lowest members of our own order. But in respect of definiteness and permanence the relations between individuals in a state of gregariousness fall far short of the relations between individuals in the rudest human society. The primordial unit of human society is the family, and it was by the establishment of definite and permanent family relationships that the step was taken which raised Man socially above the level of gregarious apehood. This great point was attained through that lengthening of the period of helpless childhood which accompanied the gradually increasing intelligence of our half-human ancestors. When childhood had come to extend over a period of ten or a dozen years—a period which would be doubled, or more than doubled, where several children were born in succession to the same parents—the relationships between father and mother, brethren and sisters, must have become firmly knit; and thus the family, the unit of human society, gradually came into existence.[11] The rudimentary growth of moral sentiment must now have received a definite direction. As already observed, with the beginnings of infancy in the animal world there came the genesis in the parents of feelings and actions not purely self-regarding. Rudimentary sympathies, with rudimentary capacity for self-devotion, are witnessed now and then among higher mammals, such as the dog, and not uncommonly among apes. But as the human family, with its definite relationships, came into being, there must necessarily have grown up between its various members reciprocal necessities of behaviour. The conduct of the individual could no longer be shaped with sole reference to his own selfish desires, but must be to a great extent subordinated to the general welfare of the family. And in judging of the character of his own conduct, the individual must now begin to refer it to some law of things outside of himself; and hence the germs of conscience and of the idea of duty. Such were no doubt the crude beginnings of human morality.
