This outrageous parental selfishness and tyranny, so detrimental to the interests of the human race, was gradually mitigated as civilization progressed in Europe. Marriages were no longer made for the benefit of the parents alone, but with a view to the comfort and worldly advantages of the couple to be wedded. But rank, money, dowry, continued—and continue in Europe to this day—to be the chief matchmakers, few parents rising to the consideration of the welfare of the grandchildren. The grandest task of the morality of the future will be to make parental altruism extend to these grandchildren; that is, to make parents and everyone else abhor and discountenance all marriages that do not insure the health and happiness of future generations. Love will show the way. Far from being useless or detrimental to the human race, it is an instinct evolved by nature as a defence of the race against parental selfishness and criminal myopia regarding future generations.

Plato observed in his Statesman (310) that

"most persons form marriage connections without due regard to what is best for procreation of children." "They seek after wealth and power, which in matrimony are objects not worthy even of serious censure."

But his remedy for this evil was, as we have seen (775), quite as bad as the evil itself, since it involved promiscuity and the elimination of chastity and family life. Love accomplishes the results that Plato and Lycurgus aimed at, so far as healthy offspring is concerned, without making the same sacrifices and reducing human marriage to the level of the cattle-breeder. It accomplishes, moreover, the same result that natural selection secures, and without its cruelty, by simply excluding from marriage the criminal, vicious, crippled, imbecile, incurably diseased and all who do not come up to its standard of health, vigor, and beauty.

While claiming that love is an instinct developed by nature as a defence against the short-sighted selfishness of parents who would sacrifice the future of the race to their own advantage or that of their children, I do not forget that in the past it has often secured its results in an illegitimate way. That, however, was no fault of its own, being due to the artificial and foolish obstacles placed in its way. Laws of nature cannot be altered by man, and if the safety valve is tied down the boiler is bound to explode. In countries where marriages are habitually arranged by the parents with reference to rank or money alone, in defiance of love, the only "love-children" are necessarily illegitimate. This has given rise to the notion that illegitimate children are apt to be more beautiful, healthy, and vigorous than the issue of regular marriages: and, under the circumstances, it was true. But for this topsy-turvyness, this folly, this immorality, we must not blame love, but those who persistently thwarted love—or tried to thwart it. As soon as love was allowed a voice in the arrangement of marriages illegitimacy decreased rapidly. Had the rights of love been recognized sooner, it would have proved a useful ally of morality instead its craftiest enemy.[335]

The utility of love from a moral point of view can be shown in other ways. Many tendencies—such as club life, the greater ease of securing divorces, the growing independence of women and their disinclination to domesticity—are undermining that family life which civilization has so slowly and laboriously built up, and fostering celibacy. Now celibacy is not only unnatural and detrimental to health and longevity, but it is the main root of immorality. Its antidote is love, the most persuasive champion and promoter of marriage. No reader of the present volume can fail to see that man has generally managed to have a good time at the expense of woman and it is she who benefits particularly by the modern phases of love and marriage. Yet in recent years the notion that family life is not good enough for women, and that they should be brought up in a spirit of manly independence, has come over society like a noxious epidemic. It is quite proper that there should be avenues of employment for women who have no one to support them; but it is a grievous error to extend this to women in general, to give them the education, tastes, habits, sports, and politics of the men. It antagonizes that sexual differentiation of the more refined sort on which romantic love depends and tempts men to seek amusement in ephemeral, shallow amours. In plain English, while there are many charming exceptions, the growing masculinity of girls is the main reason why so many of them remain unmarried; thus fulfilling the prediction: "Could we make her as the man, sweet love were slain." Let girls return to their domestic sphere, make themselves as delightfully feminine as possible, not trying to be gnarled oaks but lovely vines clinging around them, and the sturdy oaks will joyously extend their love and protection to them amid all the storms of life. In love lies the remedy for many of the economic problems of the day.

There is not one of the fourteen ingredients of romantic love which cannot be shown to be useful in some way. Of individual preference and its importance in securing a happy blend of qualities for the next generation I have just spoken, and I have devoted nearly a page (131) to the utility of coyness. Jealousy has helped to develop chastity, woman's cardinal virtue and the condition of all refinement in love and society. Monopolism has been the most powerful enemy of those two colossal evils of savagery and barbarism—promiscuity and polygamy; and it will in future prove as fatal an enemy to all attempts to bring back promiscuity under the absurd name of "free love," which would reduce all women to the level of prostitutes and make men desert them after their charms have faded. Two other ingredients of love—purity and the admiration of personal beauty—are of great value to the cause of morality as conquerors of lust, which they antagonize and suppress by favoring the higher (mental) sexual qualities; while the sense of beauty also co-operates with the instinct which makes for the health of future generations; beauty being simply the flower of health, and inheritable.

At first sight it may seem difficult to assign any use to the pride, the hyperbole, and the mixed moods which are component elements of love; but they are of value inasmuch as they exalt the mind, and give to the beloved such prominence and importance that the way is paved for the altruistic ingredients of romantic love, the utility of which is so obvious that it hardly needs to be hinted at. If love were nothing more than a lesson in altruism—with many the first and only lesson in their lives—it would be second in importance to no other factor of civilization. Sympathy lifts the lover out of the deep groove of selfishness, teaching him the miracle of feeling another's pains and pleasures more keenly than his own. Man's adoration of woman as a superior being—which she really is, as the distinctively feminine virtues are more truly Christian and have a higher ethical value than the masculine virtues—creates an ideal which has improved women by making them ambitious to live up to it. No one, again, who has read the preceding pages relating to the treatment of women before romantic love existed, and compares it with their treatment at present, can fail to recognize the wonderful transformation brought about by gallantry and self-sacrifice—altruistic habits which have changed men from ruffians to gentlemen. I do not say that love alone is responsible for this improvement, but it has been one of the most potent factors. Finally, there is affection, which, in conjunction with the other altruistic ingredients of love, has changed it from an appetite like that of a fly for sugar to a self-oblivious devotion like a mother's for her child, thus raising it to the highest ethical rank as an agency of culture.

We are still very far from the final stage in the evolution of love. There is no reason to doubt that it will continue to develop, as in the past, in the direction of the esthetic, supersensual, and altruistic. As a physician's eye becomes trained for the subtle diagnosis of disease, a clergyman's for the diagnosis of moral evil, so will the love-instinct become more and more expert, critical, and refined, rejecting those who are vicious or diseased. Compare the lustrous eyes of a consumptive girl with the sparkling eyes of a healthy maiden in buoyant spirits. Both are beautiful, but to a doctor, or to anyone else who knows the deadliness and horrors of tuberculosis, the beauty of the consumptive girl's eyes will seem uncanny, like the charm of a snake, and it will inspire pity, which in this case is not akin to love, but fatal to it. Thus may superior knowledge influence our sense of beauty and liability to fall in love. I know a man who was in love with a girl and had made up his mind to propose. He went to call on her, and as he approached the door he heard her abusing her mother in the most heartless manner. He did not ring the bell, and never called again. His love was of the highest type, but he suppressed his feelings.

More important than the further improvement of romantic love is the task of increasing the proportion of men and women who will be capable of experiencing it as now known to us. The vast majority are still strangers to anything beyond primitive love. The analysis made in the present volume will enable all persons who fancy themselves in love to see whether their passion is merely self-love in a roundabout way or true romantic affection for another. They can see whether it is mere selfish liking, attachment, or fondness, or else unselfish affection. If adoration, purity, sympathy, and the altruistic impulses of gallantry and self-sacrifice are lacking, they can be cultivated by deliberate exercise:
