The examples of female faithfulness that can be adduced against this are of little value. They are either the slow result of the habit of sexual acquiescence, or a condition of actual slavery, dog-like, attentive, full of instinctive tenacious attachment, comparable with that necessity for actual contact which marks female sympathy. The conception of faithfulness to one has been created by man. It arises from the masculine idea of individuality which remains unchanged by time, and, therefore, needs as its complement always one and the same person. The conception of faithfulness to one person is a lofty one, and finds a worthy expression in the sacramental marriage of the Catholic Church. I am not going to discuss the question of marriage or free-love. Marriage in its existing form is as incompatible as free-love with the highest interpretations of the moral law. And so divorce came into the world with marriage. None the less marriage could have been invented only by man. No proprietary institution originated with women. The introduction of order into chaotic sexual relations could have come only through man’s desire for it, and his power to establish it. There have been periods in the history of many primitive races in which women had great influence; but the period of matriarchy was a period of polyandry. The dissimilarity in the relations of mother and prostitute to their child is rich in important conclusions. A woman in whom the prostitute element is strong will perceive her son’s manhood and always stand in a sexual relation to him. But as no woman is the perfect type of mother, there is something sexual in the relation of every mother and son. For this reason, I chose the relation of the mother to her daughter and not to her son, as the best measure of her type. There are many well-known physiological parallels between the relations of a mother to her children and of a wife to her husband. Motherliness, like sexuality, is not an individual relation. When a woman is motherly the quality will be exercised not only on the child of her own body, but towards all men, although later on her interest in her own child may become all-absorbing and make her narrow, blind, and unjust in the event of a quarrel.
