_Marital Love._—This form of love, the affection between husband and wife, is also of comparatively late growth. In general, it requires monogamy. Frequently it is at war with romantic love. In early centuries, there was no thought of love when a union between two persons was arranged. The mating was planned for political or monetary reasons. Then, when romantic love sprang up, certain young people rebelled against this cold-blooded way of disposing of their lives, and chose to marry for love. Often this is no more satisfactory than the commercial method. In many European countries, the two are still divorced. In France, the wife and the mistress are both socially acknowledged facts, but are rarely embodied in the same person. In America there is a growing tendency to make wife and mistress always one and the same person. This is the ideal situation, though it is by far the more difficult of consummation. It is a sin to yield one’s body to a man whom one does not love. _The Psychological View of Love._—Freud, who blames most of man’s unhappiness on improper sex-knowledge and development, divides the growth of love in the human being into three stages: 1. Auto-eroticism, or self-love. 2. Homosexuality, or love of the same sex. 3. Heterosexuality, or love of the opposite sex. The infant is always auto-erotic. It gains its first pleasure from suckling the mother’s breasts, or the bottle. Soon it discovers the pleasure of this apart from the mere joy of eating. Then it sucks anything handy. It will suck an empty bottle, a toy, its thumb. This practice naturally should be discouraged, chiefly because it is deforming to the mouth. Soon the child discovers its own body. It finds real joy in handling its own body. The normal child grows out of this stage as it grows out of safety pins and bibs. There are cases where the child does not grow out of this phase of life. Something goes wrong, and the child’s development is arrested, and throughout life he or she remains a victim of self-love. The next thing that the normal child realizes is the existence of other persons in the world. This realization naturally centers on children. The grown-ups are very remote. Children come to have reality for the small child. She recognizes something akin to herself, and, since she has no way of knowing differently, she assumes that all children are physically equipped like herself. Boys and girls are alike to her; she does not know that there is any difference, other than clothes, between them. Her affections are drawn away from herself to others, and usually center upon some older girl. This is the period of homosexuality. Its most common manifestation is the schoolgirl “crush” on an older girl, or a favorite woman teacher. This is the most dangerous period for the girl’s future happiness. If she chances to place her affection in a girl or a woman who is emotionally biased, she may ruin her life or, at least, seriously damage it.
