Probably the earliest human societies, in the opening stages of the true human story, were small family groups. Just as the flocks and herds of the earlier mammals arose out of families which remained together and multiplied, so probably did the earliest tribes. But before this could happen a certain restraint upon the primitive egotisms of the individual had to be established. The fear of the father and respect for the mother had to be extended into adult life, and the natural jealousy of the old man of the group for the younger males as they grew up had to be mitigated. The mother on the other hand was the natural adviser and protector of the young. Human social life grew up out of the reaction between the crude instinct of the young to go off and pair by themselves as they grew up, on the one hand, and the dangers and disadvantages of separation on the other. An anthropological writer of great genius, J. J. Atkinson, in his _Primal Law_, has shown how much of the customary law of savages, the _Tabus_, that are so remarkable a fact in tribal life, can be ascribed to such a mental adjustment of the needs of the primitive human animal to a developing social life, and the later work of the psycho- analysts has done much to confirm his interpretation of these possibilities. Some speculative writers would have us believe that respect and fear of the Old Man and the emotional reaction of the primitive savage to older protective women, exaggerated in dreams and enriched by fanciful mental play, played a large part in the beginnings of primitive religion and in the conception of gods and goddesses. Associated with this respect for powerful or helpful personalities was a dread and exaltation of such personages after their deaths, due to their reappearance in dreams. It was easy to believe they were not truly dead but only fantastically transferred to a remoteness of greater power.
