The great minds of the 20th century have generally rejected sentimentalism, even defining its essence as false, exaggerated emotion; and we tend to find mawkish or even comical much that the Romantic age prized as moving and beautiful. Yet there was more than cheap self-indulgence and escapism in this fevered emotionalism. Its proponents argued that one could be morally and spiritually uplifted by cultivating a greater sensitivity to feelings. The cultivation of empathy for the sufferings of others could even be a vehicle for social change, as in the works of Charles Dickens. That this emotionalism was sometimes exaggerated or artificial should not obscure the fact that it also contained much that was genuine and inspiring. It is not clear that we have gained so much by prizing in our modern literature attitudes of cynicism, detachment, and ruthlessness.
Of all the emotions celebrated by the Romantics, the most popular was love. Although the great Romantic works often center on terror or rage, the motive force behind these passions is most often a relationship between a pair of lovers. In the classical world love had been more or less identical with sex, the Romans treating it in a particularly cynical manner. The Medieval troubadours had celebrated courtly adultery according to a highly artificial code that little reflected the lives of real men and women while agreeing with physicians that romantic passion was a potentially fatal disease. It was the romantics who first celebrated romantic love as the natural birthright of every human being, the most exalted of human sentiments, and the necessary foundation of a successful marriage. Whether or not one agrees that this change of attitude was a wise one, it must be admitted to have been one of the most influential in the history of the world.
This is not the place to trace the long and complex history of how the transcendent, irrational, self-destructive passion of a Romeo and Juliet came to be considered the birthright of every European citizen; but this conviction which continues to shape much of our thinking about relationships, marriage, and the family found its mature form during the Romantic age. So thoroughly has love become identified with romance that the two are now generally taken as synonyms, disregarding the earlier associations of "romance" with adventure, terror, and mysticism.
