INTRODUCTION

The Great War has caused a vast destruction of the sounder portion of
the belligerent peoples and it is certain that in the next generation
the progeny of their weaker members will constitute a much larger
proportion of the whole than would have been the case if the War had not
occurred. Owing to this immeasurable calamity that has befallen the
white race, the question of eugenics has ceased to be merely academic.
It looms large whenever we consider the means of avoiding a stagnation
or even decline of our civilization in consequence of the losses the War
has inflicted upon the more valuable stocks. Eugenics is by no means
tender with established customs and institutions, and once it seemed
likely that its teachings would be left for our grandchildren to act on.
But the plowshare of war has turned up the tough sod of custom, and now
every sound new idea has a chance. Rooted prejudices have been leveled
like the forests of Picardy under gun fire. The fear of racial decline
provides the eugenist with a far stronger leverage than did the hope of
accelerating racial progress. It may be, then, that owing to the War
eugenic policies will gain as much ground by the middle of this century
