Now may we not claim Plato as a precursor of the modern eugenics movement? He grasped the intensity of inheritance, for he appeals to the herd and the flock; he realized the danger to the state of a growing band of degenerates, and he called upon the legislator to purify the state. Plato's purgation, if you will accept the view I have endeavored to lay before you to-day, has in fact hitherto been carried out by natural selection, by the struggle of man against man, of man against nature, and of state against state. This very cosmical process has so developed our ethical feelings that we find it difficult to regard the process as benign. A hundred years ago we still hung the greater proportion of our criminals or sent them for life across the seas, not even euphemistically terming it a "colony." We shut up our insane, making no attempt at cure; the modern system of hospitals and institutions and charities was scarcely developed; the physically and mentally weak had small chance of surviving and bearing offspring. There was a constant stern selection purifying in Plato's sense the state. The growth of human sympathy—and is not this one of the chief factors of national fitness?—has been so rapid during the century that it has cried Halt! to almost every form of racial purification. Is not this the real opposition which Huxley noticed between the ethical and cosmic processes? One factor—absolutely needful for race survival—sympathy, has been developed in such an exaggerated form that we are in danger, by suspending selection, of lessening the effect of those other factors which automatically purge the state of the degenerates in body and mind.
Do I therefore call for less human sympathy, for more limited charity, and for sterner treatment of the weak? Not for a moment:
