The activities of man which are in the "not natural" class may be either desirable for the individual and the race, or else undesirable for both. Therefore, it will be seen, all such activities must be subjected to the test of reason and experience in order to determine whether they are in the best interests of the individual and the race, or else opposed to these. This is the only sane method of testing the validity and desirability of such things--Birth Control among the others. The claim of "not natural," if applied at all, must be extended to ALL things which are not strictly "natural" or instinctive--it is casuistical to apply the term in reproach to certain things and to withhold it from others in the same general class. LESSON XIV RACE SUICIDE A favorite argument of certain opponents of scientific Birth Control is that such teachings and modes of conduct tend toward Race Suicide, and the consequent weakening and final destruction of the human race by means of "bleeding it white" by draining from it its normal supply of children. Those who hold this view argue that if Birth Control methods become popular, and sanctioned by the law and public opinion, then the race will eventually die out and disappear from the face of the earth. Some vary the argument by insisting that those nations favoring Birth Control would suffer decline and gradual extinction at the hands of other nations opposed to scientific methods of regulating the number and frequency of offspring. This is a serious charge against Birth Control, which if proved would probably serve to array all right-thinking persons against it. But the advocates of Birth Control seriously and positively controvert and deny the validity and truth of this argument. On the contrary they claim that scientific Birth Control would not only keep up the population of all countries, or any country, to a normal standard proportionate to its ability to sustain properly such population, but will also act to render that population stronger and better, physically, mentally and morally, and far more efficient in every way owing to improved quality of the stock. The first requisite is met by THE REDUCTION OF THE DEATH RATE to meet the decreasing birth-rate; and the second requisite is met by the improvement of the stock by proper rearing and training made possible by the decreased size of the average family. BIRTH CONTROL SERVES TO ELIMINATE THE WASTE CAUSED BY EXCESSIVE INFANT MORTALITY, and to thus fully counterbalance the decreased birth rate.
