(8) There are, besides, certain practical consequences of which experience warns. Free love would mean that the pretty and well- developed girls, the handsomer and physically stronger men, would be besieged with solicitations and almost inevitably debauched by excess of temptation, while the less attractive would starve for love. It would mean jealousies, deserted lovers, and broken hearts. Free love is especially hard on a woman; she readily becomes attached, and craves loyalty. Inconstancy, though it is so natural to man as often to need the pressure of law and convention for its repression, is not only the worst enemy of his own happiness, but the inevitable source of friction and clash between men and between women. If freedom to break the troth that love instinctively plights is allowed, the chances are numerous that one or the other will some day discover another "affinity" that, at least for the time, seems closer and better suited to him; unless a stern loyalty prevents, one or two or three hearts may be broken. Our monogamous code-whose iological value is clearly indicated by its adoption by most of the higher animals (not counting the domesticated animals, whose morals have been hopelessly ruined)-stands among the wisest of our ideals. What safeguards against unchastity are necessary? Overwhelming as is the argument for monogamy, it runs counter to such violent impulses that it needs every prop and sanction that can be given it. It must shelter itself under the law, keep on its side the conscience of men, and be hallowed by alliance with religion. All this is partially attained by the social-religious institution of marriage. The wedding ceremony itself, adding as it does dignity and symbolism, the memory of a beautiful occasion, and the witness of friends to the plighting of mutual vows, is of appreciable value. We must now consider the practical question how, in the face of almost inevitable temptation, the young man and woman may keep chaste during the years prior to marriage. If pre-marital chastity is maintained, there is comparatively little danger of infidelity when chosen love and loyalty to vows come to reinforce the earlier motives.
