An extremely important question is that of the procreation of children. We have just explained how this can be regulated at will; we have now to consider how children of the best quality can be procreated.

The first condition is the good quality of the parents. Their heredity or the intellectual and physical value of their ancestry is of paramount importance. We must take into consideration, not only the intelligence and physical health, but also good sentiments, a conscientious character and energy of will. What is the use of procreating healthy and robust children if they are vain, egoistic, impulsive, crafty, wanting in will power, or perhaps criminal? Such individuals constitute a social plague.

At the time of conception the parents should not be in a condition of acute or chronic alcoholism, nor affected with any disease; otherwise the progeny may be tainted by blastophthoria (Chapter I).

The age of the procreators should also be taken into account. Children born of parents advanced in years are generally feeble.

The fatal error which causes the procreation of children to depend on pecuniary reasons and interests is a social misfortune. Healthy men and women ought never to avoid reproduction, even when they are poor. Progeny of good quality grow up, so to speak, by themselves. Progeny with evil instincts, or decadent, have a pre-existing hereditary taint, or have been affected by blastophthoria in some other way.

No doubt acquired diseases or accidents may make an invalid of a child or a man, but these are exceptions which prove the rule, for here again the descendant of healthy parents is more resistant than others, if he has not artificially altered his state of health and power of resistance by alcohol or venereal disease.

Among savages, and at the present day among many peasants, children are rather an advantage than a burden, because these people have simple and healthy habits and few wants. It is our artificial and unhealthy desire for luxury, frivolity, comfort and enjoyment, our muscular weakness resulting from want of exercise, our exaggerated terror of diseases and microbes, in a word our effeminacy, which makes us so incapable of rearing large families simply and cheaply. No doubt it becomes more and more necessary to give children a good education, and this necessity complicates the question. But, in my opinion this education will in the future be conducted by the State.

Hygiene of Pregnancy.—This subject is too special to be fully dealt with here. We may, however, mention that idleness and overwork are equally detrimental to the pregnant woman and her child. It is needless to say that every pregnant woman requires care and good food. Violent efforts, especially in the upright position, should be avoided (vide Bachimont: La Puericulture intra-uterine, 1898, Paris). But domestic work and moderate exercise of the body are beneficial. Precautions are especially necessary during the last months of pregnancy for the general health of the mother and child, but imprudence during the early months may cause abortion in many women. The progressive enervation of women in easy circumstances has no doubt rendered them less adapted to procreation. This failing should be corrected by progressive but prudent training.

Medical Advice as to Marriage.—The permission or prohibition of marriage is a delicate question at the present day, but will be less so in the future, if our propositions are realized. If one of the two candidates for matrimony has been or is still insane, or seriously affected with tuberculosis, or with active syphilis or chronic gonorrhea, it is clearly our duty to prohibit marriage.

If the situation is not so grave, and if it is only a question of hereditary taint, especially when there is a probability of the offspring being deformed in body or mind, we may content ourselves with prohibiting the procreation of children, while giving permission for marriage, provided anticonceptional measures are used. The importance of these measures is obvious in such cases. We should explain to the young people in question that the procreation of unhealthy or backward children is bad and even criminal, and warn them against such an unpardonable act of thoughtlessness. If they are very fond of children they can be recommended to adopt poor orphans.
