It may be added that, in historical instances, civilisations have, on the one hand, persisted, and, on the other, fallen, despite change, and even substitution, in the races which created them: and, on the other hand, the most conspicuously persistent of all races in the historic epoch, the Jews, have survived one Empire after another of their oppressors, but have never had an Empire of their own. Thus, so far as the historian is concerned, it is not races at all that die, but civilisations and Empires. Plato's argument from the individual to the race is therefore irrelevant, as well as untrue. The fatalistic conception to which it tempts us, saying that races must die, just as individuals must, and that therefore it is idle to repine or oppose, is utterly unwarrantable and extremely unhealthy. To take our own case, despite the talk about our own racial decadence, nearly all our babies still come into the world fit and strong and healthy--the racial poisons apart. We kill them in scores of thousands every year, but this infant mortality is not a sign that the race is dying, but a sign that even the most splendid living material can be killed or damaged if you try hard enough. The babies do not die because races are mortal, but because individuals are and we kill them. The babies drink poison, eat poison, and breathe poison, and in due course die. The theory of racial senility, inapplicable everywhere because untrue, is most of all inapplicable here. If a race became sterile, Plato and Aristotle would be right. There is no such instance in history, apart from well-defined external, _not inherent_, causes, as in the case of the Tasmanians. Dismissing this analogy, we may also dismiss, as based upon nothing better, the idea that the great tragedies of history were necessary events at all. We must look elsewhere than amongst the inherent and necessary factors of racial life for the causes which determine these tragedies; and we shall be entitled to assume as conceivable the proposition that, notwithstanding the consistent fall of all our predecessors, the causes are not inevitable, but, being external and environmental, may possibly be controlled: man being not only creature but creator also.
