This philosophy of living which I have called American idealism is in its own nature sound, as is proved in a hundred directions where it has had full play. Suppressed idealism, like any other suppressed desire, becomes unsound. And here lies the ultimate cause of the taste for sentimentalism in the American _bourgeoisie._ An undue insistence upon happy endings, regardless of the premises of the story, and a craving for optimism everywhere, anyhow, are sure signs of a "morbid complex," and to be compared with some justice to the craving for drugs in an alcoholic deprived of liquor. No one can doubt the effect of the suppression by the Puritan discipline of that instinctive love of pleasure and liberal experience common to us all. Its unhealthy reaction is visible in every old American community. No one who faces the facts can deny the result of the suppression by commercial, bourgeois, prosperous America of our native idealism. The student of society may find its dire effects in politics, in religion, and in social intercourse. The critic cannot overlook them in literature; for it is in the realm of the imagination that idealism, direct or perverted, does its best or its worst. Sentiment is not perverted idealism. Sentiment _is_ idealism, of a mild and not too masculine variety. If it has sins, they are sins of omission, not commission. Our fondness for sentiment proves that our idealism, if a little loose in the waist-band and puffy in the cheeks, is still hearty, still capable of active mobilization, like those comfortable French husbands whose plump and smiling faces, careless of glory, careless of everything but thrift and good living, one used to see figured on a page whose superscription read, "Dead on the field of honor." The novels, the plays, the short stories, of sentiment may prefer sweetness, perhaps, to truth, the feminine to the masculine virtues, but we waste ammunition in attacking them. There never was, I suppose, a great literature of sentiment, for not even "The Sentimental Journey" is truly great. But no one can make a diet exclusively of "noble" literature; the charming has its own cozy corner across from the tragic (and a much bigger corner at that). Our uncounted amorists of tail-piece song and illustrated story provide the readiest means of escape from the somewhat uninspiring life that most men and women are living just now in America.
