But is it anything of the kind? It would appear to be doubtful. If the sole purpose of marriage is to rear children, a man ought to live with a woman only until she becomes pregnant, and, after that moment, he ought not to touch her. But here begins the second part. The woman bears a baby; the baby is nourished by the mother's milk. The man has no right to co-habit with his wife during this period either, because it will be at the risk of depriving the child of its natural source of nutriment.
In consequence, a man must either co-habit with his wife once in two years, or else there will be some default in the marriage.
What is he to do? What is the moral course? Remember that three factors have combined to impose the marriage. One, the most far-reaching today, is economic; another, which is also extremely important, is social, and the third, now rapidly losing its hold, but still not without influence, is religious. The three forces together attempt to mould nature to their will.
Economic pressure and the high cost of living make against the having of children. They encourage default.
"How are we to have all these children?" the married couple asks. "How can we feed and educate them?"
Social pressure also tends in the same direction. Religious morality, however, still persists in its idea of sin, although the potency of this sanction is daily becoming less, even to the clerical eye.
If nature had a vote, it would surely be cast in favour of polygamy. Man is forever sexual, and in equal degree, until the verge of decrepitude. Woman passes through the stages of fecundation, pregnancy, and lactation.
There can be no doubt but that the most convenient, the most logical and the most moral system of sexual intercourse, naturally, is polygamy.
But the economic subdues the natural. Who proposes to have five wives when he cannot feed one?
Society has made man an exclusively social product, and set him apart from nature.
