Nature herself in times of great poverty or bad climatic conditions, as well as poor harvest, intervenes to restrict the increase of population of certain countries or races; this, to be sure, by a method as wise as it is ruthless. She diminishes, not the power of procreation as such, but the conservation of the procreated, by exposing them to hard trials and deprivations with the result that all those who are less strong and less healthy are forced back into the womb of the eternak ubknown, Those whom she permits to survive the inclemency of existence are a thousandfold tested, hardened, and well adapted to procreate in turn, in order that the process of thoroughgoing selection may begin again from the beginning. By thus brutally proceeding against the individual and immediately calling him back to herself as soon as he shows himself unequal to the storm of life, she keeps the race and species strong, in fact, raises them to the highest accomplishments. At the same time the diminution of number strengthens the individual and thus in the last analysis fortifies the species.
