In this and other ways we find that polygamy was threatened on many sides. As an accepted and legalised form of marriage it tends to disappear with the conditions under which social life is developed. Like the maternal marriage, and other primitive experiments in sexual associations, polygamy is not a form of marriage that can be regarded as a permanent expression of the marriage law: that is, it is experimental and suitable to special conditions; it is not a final form, growing up by custom from earlier practices, or one which strives for mastery and will not tolerate other co-existent forms. On the other hand, monogamy has always been characterised by the strongest self-assertion, and from the earliest times we find it triumphing, and more and more seeking to exclude other forms of marriage. These facts of the past history of marriage need to be considered by those who seek to bring discredit on monogamous marriage. Various reformers, too frightenedly concerned with the present shortage of men, increasing as it will enormously the disproportion between the number of the two sexes, have jumped to the conclusion that polygamy is likely to be legalised in the near future. I do not believe it. At least, it will not be polygamy under the form we have known it in the past. Polygamy has always been connected with the property value of woman and is dependent upon wealth. For this reason, even if for no other, polygamy will not replace monogamous marriages. Such a marriage system could not be supported by war-impoverished countries. The remedy must be a different one, as presently I shall show. There is a strange idea among some people that sexual happiness can be gained by breaking away from the traditional bonds; it is the visible sign of our confusion as a people and the want of happiness in our lives. We should not set at naught the experience of the ages. Polygamy is an institution which in the growth of civilisation belongs only to primitive or non-progressive states. No race or nation has ever risen to front rank, or even secondary rank, under this marriage system. Our preference for monogamy goes beyond laws and religions. It is that deeply rooted thing—a matter of racial experience and desire. It is the best way that we have yet found of men and women living together.
