These conditions do not obtain at first among immigrants, and large families among the newly arrived population are still the rule, precisely as they were in Colonial America and are to-day in French Canada where backwoods conditions still prevail.
The result is that one class or type in a population expands more rapidly than another and ultimately replaces it. This process of replacement of one type by another does not mean that the race changes or is transformed into another. It is a replacement pure and simple and not a transformation.
The lowering of the birth rate among the most valuable classes, while the birth rate of the lower classes remains unaffected, is a frequent phenomenon of prosperity. Such a change becomes extremely injurious to the race if unchecked, unless nature is allowed to maintain by her own cruel devices the relative numbers of the different classes in their due proportions. To attack race suicide by encouraging indiscriminate reproduction is not only futile but is dangerous if it leads to an increase in the undesirable elements. What is needed in the community most of all is an increase in the desirable classes, which are of superior type physically, intellectually and morally and not merely an increase in the absolute numbers of the population.
The value and efficiency of a population are not numbered by what the newspapers call souls, but by the proportion of men of physical and intellectual vigor. The small Colonial population of America was, on an average and man for man, far superior to the present inhabitants, although the latter are twenty-five times more numerous. The ideal in eugenics toward which statesmanship should be directed is, of course, improvement in quality rather than quantity. This, however, is at present a counsel of perfection and we must face conditions as they are.
The small birth rate in the upper classes is to some extent offset by the care received by such children as are born and the better chance they have to become adult and breed in their turn. The large birth rate of the lower classes is under normal conditions offset by a heavy infant mortality, which eliminates the weaker children.
Where altruism, philanthropy or sentimentalism intervene with the noblest purpose and forbid nature to penalize the unfortunate victims of reckless breeding, the multiplication of inferior types is encouraged and fostered. Indiscriminate efforts to preserve babies among the lower classes often result in serious injury to the race. At the existing stage of civilization, the legalizing of birth control would probably be of benefit by reducing the number of offspring in the undesirable classes. Regulation of the number of children is, for good or evil, in full operation among the better classes and its recognition by the state would result in no further harm among them.
Mistaken regard for what are believed to be divine laws and a sentimental belief in the sanctity of human life tend to prevent both the elimination of defective infants and the sterilization of such adults as are themselves of no value to the community. The laws of nature require the obliteration of the unfit and human life is valuable only when it is of use to the community or race.
It is highly unjust that a minute minority should be called upon to supply brains for the unthinking mass of the community, but it is even worse to burden the responsible and larger but still overworked elements in the community with an ever increasing number of moral perverts, mental defectives and hereditary cripples. As the percentage of incompetents increases, the burden of their support will become ever more onerous until, at no distant date, society will in self-defense put a stop to the supply of feebleminded and criminal children of weaklings.
The church assumes a serious responsibility toward the future of the race whenever it steps in and preserves a defective strain. The marriage of deaf mutes was hailed a generation ago as a triumph of humanity. Now it is recognized as an absolute crime against the race. A great injury is done to the community by the perpetuation of worthless types. These strains are apt to be meek and lowly and as such make a strong appeal to the sympathies of the successful. Before eugenics were understood much could be said from a Christian and humane viewpoint in favor of indiscriminate charity for the benefit of the individual. The societies for charity, altruism or extension of rights, should have in these days, however, in their management some small modicum of brains, otherwise they may continue to do, as they have sometimes done in the past, more injury to the race than black death or smallpox.
As long as such charitable organizations confine themselves to the relief of suffering individuals, no matter how criminal or diseased they may be, no harm is done except to our own generation and if modern society recognizes a duty to the humblest malefactors or imbeciles that duty can be harmlessly performed in full, provided they be deprived of the capacity to procreate their defective strain.
