Dr. Wallace is a socialist, and he believes that only through socialism can we achieve “that perfect freedom of choice in marriage which will only be possible when all are economically equal, and no question of social rank or material advantage can have the slightest influence in determining that choice.” As I have said elsewhere, I would call myself neither a socialist nor an anti-socialist, but if labels are necessary, a eugenist and maternalist. As such, I can only say that this argument for socialism--that it is the necessary condition of eugenics or race-culture--is, for me, incomparably the best argument for that creed; and if it were proved that only through socialism could the utmost be made of women's choice of husbands, then no argument against socialism could have any appreciable weight at all. The fundamental and permanent argument against certain of the highly various and incompatible doctrines which, for our confusion, are commonly lumped together as socialism, is that they would arrest the process by which Nature rewards worth and permits it to perpetuate itself. If, then, it can be shown, as may or may not be the case, that only through socialism can male worth be most effectively chosen and male unworth be rejected for fatherhood, the supreme--that is, the eugenic--argument against socialism becomes the conclusive argument in its favour. =The field of choice.=--But, however this may be, there can be no question that the eugenic purpose, as well as the happiness and elevation of individuals in the present, will be greatly served by whatever measures increase, to the utmost extent possible, the opportunities for choice in marriage afforded to women and also to men. One of the most amazing and satisfactory facts about marriage as at present practised is, I think, the large proportion--often estimated at seventy-five per cent.--of unions which, apart from any eugenic question, turn out happily, in Great Britain, at any rate. What makes this fact more amazing is the almost incredible limitation of the field of choice within which both sexes are still confined as a whole. If the reader will consider the cases most familiar to him or her, it will surely be admitted that the considerable success of marriage takes on an astonishing aspect when the present strait conditions of choice are taken into account. I am convinced that few more radical and far-reaching, because eugenic, reforms can be conceived than any which, in accordance with Dr. Wallace's argument, tend to widen the field of choice, and that not for one sex only but for both. He would be a rash man who ventured to allot superior value to the selection of man by woman rather than of woman by man, or _vice versâ_.
