Such a statement ought to strike the reader as one of grave importance; but we labor under no delusion that it will do so. For we are painfully aware that the bugaboo of the declining birth-rate of superior people has been raised so often in late years, that it has become stale by repetition. It no longer causes any alarm. The country is filled with sincere but mentally short-sighted individuals, who are constantly ready to vociferate that numbers are no very desirable thing in a birth-rate; that quality is wanted, not quantity; that a few children given ideal care are of much more value to the state and the race than are many children, who can not receive this attention. And this attitude toward the subject, we venture to assert, is a graver peril to the race than is the declining birth-rate itself. For there is enough truth in it to make it plausible, and to separate the truth from the dangerous untruth it contains, and to make the bulk of the population see the distinction, is a task which will tax every energy of the eugenist. Unfortunately, this is not a case of mere difference of opinion between men; it is a case of antagonism between men and nature. If a race hypnotize itself into thinking that its views about race suicide are superior to nature's views, it may make its own end a little less painful; but it will not postpone that end for a single minute. The contest is to the strong, and although numbers are not the most important element in strength, it is very certain that a race made up of families containing one child each will not be the survivor in the struggle for existence. The idea, therefore, that race suicide and general limitation of births to the irreducible minimum, can be effectively justified by any conceivable appeal to economic or sociological factors, is a mistake which will eventually bring about the extinction of the people making it. This statement must not be interpreted wrongly. Certainly we would not argue that a high birth-rate in itself is necessarily a desirable thing. It is not the object of eugenics to achieve as big a population as possible, regardless of quality. But in the last analysis, the only wealth of a nation is its people; moreover some people, are as national assets, worth more than others. The goal, then, might be said to be: a population adjusted in respect to its numbers to the resources of the country, and that number of the very best quality possible. Great diversity of people is required in modern society, but of each desirable kind the best obtainable representatives are to be desired.
