One of the most important theses advanced in Romantic Love and Personal Beauty (323, 424, etc.), was that love, far from being merely a passing episode in human life, is one of the most powerful agencies working for the improvement of the human race.  During the reign of Natural Selection, before the birth of love, cripples, the insane, the incurably diseased, were cruelly neglected and allowed to perish.  Christianity rose up against this cruelty, building hospitals and saving the infirm, who were thus enabled to survive, marry, and hand down their infirmities to future generations.  As a mediator between these two agencies, love comes in; for Cupid, as I have said, “does not kill those who do not come up to his standard of health and beauty, but simply ignores and condemns them to a life of single-blessedness;” which in these days is not such a hardship as it used to be.  This thought will be enlarged in the last chapter of the present volume, on the “Utility and Future of Love,” which will indicate how the amorous sense is becoming more and more fastidious and beneficial.  In the same chapter attention will be called, for the first time, to the three great strata in the evolution of parental love and morality.  In the first, represented by savages, parents think chiefly of their own comfort, and children get the minimum of attention consistent with their preservation.  In the second, which includes most of the modern Europeans and Americans, parents exercise care that their children shall make an advantageous marriage—­that is a marriage which shall secure them wealth or comfort; but the frequency with which girls are married off to old, infirm, or unworthy men, shows how few parents as yet have a thought of their grandchildren.  In the next stage of moral evolution, which we are now entering, the grandchildren’s welfare also will be considered.  In consequence of the persistent failure to consider the grandchildren, the human race is now anything but a model of physical, intellectual, and moral perfection.  Luckily love, even in its sensual stages, has counteracted this parental selfishness and myopia by inducing young folks to marry for health, youth, and beauty, and creating an aversion to old age, disease, and deformity.  As love becomes more and more fastidious and more regardful of intellectual worth and moral beauty—­that is becomes Romantic Love—­its sway becomes greater and greater, and the time will come when questions relating to it will form the most important chapters in treatises on moral philosophy, which now usually ignore them altogether.

HOW SENTIMENTS CHANGE AND GROW

In conversation with friends I have found that the current belief that love must have been always and everywhere the same, because it is such a strong and elemental passion, is most easily shaken in this a priori position by pointing out that there are other strong feelings in our minds which were lacking among earlier and lower races.  The love of grand, wild scenery, for instance—­what we call romantic scenery—­is as modern as the romantic love of men and women.  Ruskin tells us that in his youth he derived a pleasure from such scenery “comparable for intensity only to the joy of a lover in being near a noble and kind mistress.”
