Another fact against a belief in promiscuity is that the lowest savages known to us are not promiscuous, in so far as there is no proved case of the sexual relations being absolutely unregulated. They all recognise sets of women with whom certain sets of men can have no marital relations. Again these savages are very far removed from the state of man’s first emergence from the brute, as is proved by their combination into large and friendly tribes. Such peaceful aggregation could only have arisen at a much later period, and after the males had learnt by some means to control their brute appetites and jealousy of rivals in that movement towards companionship, which, first resting in the sexual needs, broadens out into the social instincts. For these reasons, then, we conclude that the theory of a friendly union having existed among males in the primitive group is the very reverse of the truth. This question has now been sufficiently proved. I am thus brought into agreement with Dr. Westermarck, Mr. Crawley, and Mr. Lang, in his examination of Mr. Atkinson’s _Primal Law_, as well as with other writers, all of whom have shown that promiscuity cannot be accepted as a stage in the early life of the human family. I have now to show how far this rejection of promiscuity affects our position with regard to mother-descent and mother-right. It is clearly of vital importance to any theory that its foundations are secure. One foundation--that of promiscuity, on which Bachofen and McLennan, the two upholders of matriarchy, base their hypothesis--has been overthrown. It thus becomes necessary to approach the question from an altogether different position. Mother-right must be explained without any reference to unregulated sexual conduct. I am thus turned back to examine the opposing theory to matriarchy, which founds the family on the patriarchal authority of the father. Nor is this all. What we must expect a true theory to do is to show conditions that are applicable not only to special cases, but in their main features to mankind in general. I have to prove that such conditions arose in the primitive patriarchal family as it advanced towards social aggregation, that would not only make possible, but, as I believe, would necessitate the power of the mothers asserting its force in the group-family. Only when this is done can I hope that a new belief in mother-right may find acceptance.
