The breeding of men lies largely in the hands of women. That is why the question of Eugenics is to a great extent one with the woman question. The realization of eugenics in our social life can only be attained with the realization of the woman movement in its latest and completest phase as an enlightened culture of motherhood, in all that motherhood involves alike on the physical and the psychic sides. Motherhood on the eugenic basis is a deliberate and selective process, calling for the highest intelligence as well as the finest emotional and moral aptitudes, so that all the best energies of a long evolution of womanhood in the paths of modern culture here find their final outlet. The breeding of children further involves the training of children, and since the expansion of Social Hygiene renders education a far larger and more delicate task than it has ever been before, the responsibilities laid upon women by the evolution of civilization become correspondingly great. For the men who have been thus born and taught the tasks imposed by Social Hygiene are in no degree lighter. They demand all the best qualities of a selectively bred race from which the mentally and physically weak have, so far as possible, been bred out. The substitution of law for war alike in the relations of class to class, and of nation to nation, and the organization of international methods of social intercourse between peoples of different tongues and unlike traditions, are but two typical examples of the tasks, difficult but imperative, which Social Hygiene presents and the course of modern civilization renders insistent. Again, the adequate adjustment of the claims of the individual and the claims of the community, each carried to its farthest point, can but prove an exquisite test of the quality of any well-bred and well-trained race. It is exactly in that balancing of apparent opposites, the necessity of pushing to extremes both opposites, and the consequent need of cultivating that quality of temperance the Greeks estimated so highly, that the supreme difficulties of modern civilization lie. We see these difficulties again in relation to the extension of law. It is desirable and inevitable that the sphere of law should be extended, and that the disputes which are still decided by brutal and unreasoning force should be decided by humane and reasoning force, that is to say, by law. But, side by side with this extension of law, it is necessary to wage a constant war with the law-making tendency, to cherish an undying resolve to maintain unsullied those sacred and intimate impulses, all the finest activities of the moral sphere, which the generalizing hand of law can only injure and stain.
