Certainly the object of eugenics is not to merely increase human numbers. Quality is more important than quantity in a birth-rate. But it must be evident that other things being equal, a group which marries early will, after a number of generations, supplant a group which marries even a few years later. And there is abundant evidence to show that some of the best elements of the old, white, American race are being rapidly eliminated from the population of America, because of postponement or avoidance of marriage. Taking the men alone, we find that failure to marry may often be ascribed to one of the following reasons: 1. The cultivation of a taste for sexual variety and a consequent unwillingness to submit to the restraints of marriage. 2. Pessimism in regard to women from premature or unfortunate sex experiences. 3. Infection by venereal disease. 4. Deficiency in normal sexual feeling, or perversion. 5. Deficiency of one kind or another, physical or mental, causing difficulty in getting an acceptable mate. The persons in groups 4 and 5 certainly and in groups 1, 2, and 3 probably to a less extent, are inferior, and their celibacy is an advantage to the race, rather than a disadvantage, from a eugenic point of view. Their inferiority is in part the result of bad environment. But since innate inferiority is so frequently a large factor, the bad environment often being experienced only because the nature was inferior to start with, the average of the group as a whole must be considered innately inferior. Then there are among celibate men two other classes, largely superior by nature: 6. Those who seek some other end so ardently that they will not make the necessary sacrifice in money and freedom, in order to marry. 7. Those whose likelihood of early marriage is reduced by a prolonged education and apprenticeship. Prolongation of the celibate period often results in life-long celibacy. Some of the most important means of remedying the above conditions, in so far as they are dysgenic, can be grouped under three general heads: 1. Try to lead all young men to avoid a loose sexual life and venereal disease. A general effort will be heeded more by the superior than by the inferior. 2. Hold up the role of husband and father as particularly honorable, and proclaim its shirking, without adequate cause, as dishonorable. Depict it as a happier and healthier state than celibacy or pseudo-celibacy. For a man to say he has never met a girl he can love simply means he has not diligently sought one, or else he has a deficient emotional equipment; for there are many, surprisingly many, estimable, attractive, unmarried women.
