Again, impartial observation of our Christian monogamy shows us that it depends to a great extent on appearances, that it is full of trickery and hypocrisy, and that to legally enforce it for life must be considered as absolutely impossible.
In Catholic countries which prohibit divorce, the latter has been replaced by separation, and this becomes the most constant source of adultery. The more the laws of a country impede divorce, the more one must close one's eyes to promiscuity or prostitution, which has even been regulated by the State by the aid of proxenetism, all the while preaching monogamy in a loud voice.
These bitter lessons which practice has given to the partisan, of obligatory monogamy, prove the absurdity of attempting to restrain the natural appetites of man by force and by artificial obstacles. That which succeeds, not without difficulty, with some strong characters, and more easily with naturally cold temperaments, is impossible to realize in the masses.
Polyandry is usually the result of poverty, and the polyandrous races are little fecund and tend to disappear. The normal man is instinctively more polygynous than the normal woman is polyandrous. There are, however, cases where polyandry is justifiable. There are women whose sexual appetite, more or less pathological, is so insatiable that a normal man is incapable of satisfying it.
If such women were served by several Don Juans by means of a free contract, this would be better than giving themselves in despair to prostitution (there are some prostitutes created by nymphomania). This system would also be better than the seduction of normal young girls by the Don Juans in question.
Polygyny is still more indicated when the sterility of the woman or her repugnance to sexual intercourse cause family disturbances.
In speaking of polygamy in Chapter VI, we have shown that it exists in several forms, and that these are not all so humiliating for the women as people think, who only know of the shameful abuses of the Mussulman's harem. What lowers the moral level of polygyny is especially the barbarous system of marriage by purchase, by which the women become slaves burdened with heavy labor, and are in a state of legal dependence. We have seen that polygyny has a higher moral character among certain Indian tribes where matriarchism rules, and where the wife is mistress of the house and family. The danger of degradation of the woman ceases when she is equal to the man as regards rights and property. In fact, in such a social state, polygyny can only constitute an exception. It is here entirely free and becomes all the more innocent because divorce is facilitated and strict laws on the feeding and education of the children limit the male sexual appetite.
I even venture to maintain that the stability of monogamous marriage, which should be based on mutual sentiments of respect and love, would be much better guaranteed than hitherto by legal liberty of conjugal ties, and by duty to children such as I have proposed. If this became recognized as conventional, men and women fit to understand each other and love in a lasting manner, would find suitable mates more easily, and would become united more permanently when their chains were voluntary.
If marriages on trial became more frequent in the form of short unions, ending with separation, this would not be a great evil, for similar unions occur every day in a much baser form. Moreover, the effect of legislation with regard to children would put a curb on immorality and passion, which cause their worst effects.
If the objection is raised that this would lead immoral people to avoid the procreation of children so as to enjoy more varied sexual pleasures, I reply that this would be beneficial, for this anti-social class of individuals would be eliminated by sterility, by a kind of negative selection. We thus place two natural appetites in antagonism; that of procreation on the one hand, and sexual enjoyment on the other. Whoever inclines to the first, which is the higher and tends to preserve the species, is obliged to restrain himself in the second, without, however, falling into unnatural asceticism.
