to their weaker brethren. There is an immense infantile mortality in Russia. Yet, notwithstanding any resulting "survival of the fittest," Russia is far more ravaged by disease than Norway, where infantile mortality is low. "A high infantile mortality," as George Carpenter, a great authority on the diseases of childhood, remarks, "denotes a far higher infantile deterioration rate"; or, as another doctor puts it, "the dead baby is next of kin to the diseased baby," The protection of the weak, so frequently condemned by some Neo-Darwinians, is thus in reality, as Goldscheid terms it, "the protection of the strong from degeneration."
There is, however, more to be said. Not only must an undue struggle with unfavourable conditions enfeeble the strong as well as kill the feeble; it also imposes an intolerable burden upon these enfeebled survivors.
The process of destruction is not sudden, it is gradual. It is a long-drawn-out process. It involves the multiplication of the diseased, the maimed, the feeble-minded, of paupers and lunatics and criminals.
Even natural selection thus includes the need for protecting the feeble, and so renders urgent the task of social reform, while the more thoroughly this task is carried out with the growth of civilization, the more stupendous and overwhelming the task becomes.
It is thus that civilization, at a certain point in its course, renders inevitable the appearance of that wider and deeper organization of life which in the present volume we are concerned with under the name of Social Hygiene.
That movement is far from being an abrupt or revolutionary manifestation in the ordinary progress of social growth. As we have seen, social reform during the past eighty years may be said to have proceeded in four successive stages, each of which has involved a nearer approach to the sources of life.
