Sexual morality in men springs from the same economic source, but is more limited in scope and less fiercely embraced. This is a natural deduction from what has just been said. If the livelihood of women is bound up with the strict observance of the marriage tie, the maintenance of the moral restrictions upon which marriage as an institution depends is their special concern. In a purely promiscuous community the livelihood of women would be intolerably insecure. Hence women are the natural guardians of morality, knowing that it guarantees their bread and butter. It is not too much to say that morality as a going concern is kept up by women. Men on the whole, despite their strong property sense, are not interested in moral questions. They have not the woman’s delight in nosing out scandals, and, except when they are whipped up into a state of moral horror by their women folk, are much too prone to live and let live. The attitude of deliberate uncharitableness towards erring sisters which the sex affects does not come naturally to men, and left to themselves, they would condone offences which their outraged spouses insist on punishing with social ostracism. It is on the whole true to say that the moral sense, so far as sex is concerned, only begins to function in men after marriage and, except in the case of one’s own daughter whose saleable value in the marriage market is thought to be diminished by inchastity, it centres upon the wife. Since the wife is in origin a piece of property purchased by the husband for his own enjoyment, to her must be extended the jealous guardianship which presides over property in general. The wife is the most valuable of a man’s indoor possessions; in return for the use of her body he has agreed to maintain her in such dignity and leisure as he can afford. This obligation to maintain the wife is a permanent one persisting even after the enjoyment of her person has ceased. Thus when a wife divorces or lives apart from her husband, he is usually required to maintain her, so long as she remains chaste. So soon, however, as she bestows the enjoyment of her person upon another, the obligation to maintenance ceases, presumably on the ground that the new consumer should be saddled with the obligation of keeping up what he enjoys. In nothing is the property basis of marriage more clearly discernible than in the ‘dum casta’ clause of the English divorce law.
