In civilized man, on the other hand, as we know him, the situation is to some extent reversed; it is the woman who, by the display of her attractions, competes for the favour of the man. The final invitation does not come, as among animals generally, from the female; the decision rests with the man. It would be a mistake to suppose that this change reveals the evolution of a superior method; although it has developed the beauty of women, it has clearly had its origin in economic causes. The demands of nutrition have overridden those of reproduction; sexual selection has, to a large extent, given place to natural selection, a process clearly not for the advantage of the race. The changing status of women, in bestowing economic independence, will certainly tend to restore to sexual selection its due weight in human development.
In so doing it will certainly tend also to destroy prostitution, which is simply one of the forms in which the merging of sexual selection in natural selection has shown itself. Wherever sexual selection has free play, unhampered by economic considerations, prostitution is impossible.
The dominant type of marriage is, like prostitution, founded on economic considerations; the woman often marries chiefly to earn her living; here, too, we may certainly expect profound modifications.
We have long sought to preserve our social balance by placing an unreasonable licence in the one scale, an equally unreasonable abstinence in the other; the economic independence of women, tending to render both extremes unnecessary, can alone place the sexual relationships on a sound and free basis.
The State regulation of marriage has undoubtedly played a large and important part in the evolution of society. At the present time the advantages of this artificial control no longer appear so obvious (even when the evidence of the law courts is put aside); they will vanish
