The theory of mother-right has been subjected to so much criticism that a re-examination of the position is very necessary. To show its prevalence, to establish some leading points in its history, to make out its connection with the patriarchal family, and to trace the transition by which one system passed into the other, appear to me to be matters primarily important. The limited compass of this little book will prevent my substantiating my own views as I should wish, with a full and systematic survey of all authentic accounts of the peoples among whom mother-descent may be studied. I have considered, however, that I could summarise the position in a comprehensive picture, that will, I hope, suggest a point of view that seems to me to have been very generally neglected. It is necessary to enter into such an inquiry with caution; the difficulties before me are very great. Nothing would be easier than from the mass of material available to pile up facts in furnishing a picture of the high status of women among many tribes under the favourable influence of mother-descent, that would unnerve any upholders of the patriarchal view of the subordination of women. It is just possible, on the other hand, to interpret these facts from a fixed point of thought of the father’s authority as the one support of the family, and then to argue that, in spite of the mother’s control over her children and over property, she still remained the inferior partner. I wish to do neither. It is my purpose to examine the evidence, and so to discover to what extent the system of tracing descent through the female side conferred any special claim for consideration upon women. I shall try to avoid mistakes. I put forward my own opinions with great diffidence. It is so easy, as I realise full well, to interpret facts by the bias of one’s own wishes. I know that the habits and customs of primitive peoples that I have studied closely are probably few in comparison with those I have missed; yet to me they appear of such importance in the light they throw on the whole question of the relationships of the two sexes, that it seems well to bring them forward. Since my attention, now many years ago, was first directed to this question, I have felt that a clear and concise account of the mother-age was indispensable for women. Such an account, with a criticism of the patriarchal theory, is here offered. Throughout I have attempted to clear up and bring into uniformity the two opposing theories of the origin of the human family. I have tried to gather the facts, very numerous and falling into several classes, by which the theory of the mother-age could be supported. And first it was necessary to clear out of the way a body of opinion, the prevalence of which has opposed an obstacle to the acceptance of the rights of mothers in the family relationship. The whole question turns upon which you start with; the man--the woman, or the woman--the man.
