To be convincing literature must express emotion which is genuine; to commend itself to the best sense of mankind, and thus to take its place in the front rank, it must deal with emotion which is wholesome and normal. A work phrasing morbid emotion may be art, and it may be lasting; but it is not the highest art, and it does not approve itself to the best and sanest taste. Mankind looks to literature for the expression of genuine, strong, healthy human emotion; emotion passionate, tragic, painful, the exhilaration of joy or the frenzy of grief, as it may be; but always the emotion which under the given conditions would be felt by the healthy heart and soul, by the virile man and the womanly woman. No amount of insane power flashing here and there amid the foulness of Tolstoi's "Kreutzer Sonata," can reconcile the world to the fact that the book embodies the broodings of a mind morbid and diseased. Even to concede that the author of such a work had genius could not avail to conceal the fact that his muse was smitten from head to feet with the unspeakable corruption of leprosy. Morbid literature may produce a profound sensation, but it is incapable of creating a permanent impression. The principles of which we are speaking are strikingly illustrated in the tales of Edgar Allan Poe. He was possessed of an imagination narrow, but keen; uncertain and wayward, but alert and swift; individual and original, though unhappily lacking any ethical stability. In his best work he is sincere and convincing, so that stories like "The Cask of Amontillado," "The Gold Bug," or "The Purloined Letter," are permanently effective, each in its way and degree. Poe's masterpiece, "The Fall of the House of Usher," is a study of morbid character, but it is saved by the fact that this is viewed in its effect upon a healthy nature. The reader looks at everything through the mind of the imaginary narrator, so that the ultimate effect is that of an exhibition of the feelings of a wholesome nature brought into contact with madness; although even so the ordinary reader is still repelled by the abnormal elements of the theme. There is in all the work of Poe a good deal that is fantastic and not a little that is affected. He is rarely entirely sincere and sane. He shared with Byron an instinctive fondness for the rôle of a "blighted being," and a halo of inebriety too often encircles his head; yet at his best he moves us by the mysterious and incommunicable power of genius. Many of his tales, on the other hand, are mere mechanical tasks, and as such neither convincing nor permanent. There is a great deal of Poe which is not worth anybody's reading because he did not believe it, did not imagine it as real, when he wrote it. Other stories of his illustrate the futility of self-deception on the part of the author. "Lygeia" Poe always announced as his masterpiece. He apparently persuaded himself that he felt its turgid sentimentality, that he
