I sometimes think that Thalia was the daughter, and not the sister, of Melpomene. As to actual exhibition of humor, Hawthorne's is made a diffusive medium to temper the rays of tragedy with, and never appears in such unmixed form as that of Irving. So that even though we must confess a smaller mental calibre in the latter, we may gladly grant him a superiority in his special mood of fun. An excellent English critic, Leslie Stephen, lately wrote: "Poe is a kind of Hawthorne and _delirium tremens_." This announcement, however, betrays a singular misapprehension. When Hawthorne's tales first appeared, they were almost invariably taken to bear an intimate and direct relation to the author's own moods; while Poe's were supposed to be daring flights of pure imagination, or ingenious attempts to prove theories held by the writer, but were not charged directly to his own experience. Time has shown that the converse was the case. The psychical conditions described by Hawthorne had only the remotest connection with any mood of his own; they were mainly translations, into the language of genius, of certain impressions and observations drawn from the world around him. After his death, the Note-Books caused a general rustle of surprise, revealing as they did the simple, wholesome nature of this strange imaginer; yet though he there speaks--surely without prejudice, because without the least knowledge that the world would ever hear him--of "the objectivity" of his fictions, critics have not yet wholly learned how far apart from himself these creations were. The observation of some mental habit in men, or law of intercourse between human beings, would strongly present itself to him; and in order to get a concise embodiment, his genius planned some powerful situation to illustrate it with; or, at another time it might be that a strange incident, like that of Mr. Moody, suggesting "The Minister's Black Veil," or a singular physiological fact like that on which "The Bosom Serpent" is based, would call out his imagination to run a race with reality and outstrip it in touching the goal of truth. But, the conception once formed, the whole fictitious fabric would become entirely removed from _himself_, except so far as it touched him very incidentally; and this expulsion of the idea from himself, so that it acquires a life and movement of its own, and can be contemplated by the artist from the outside, is the very distinction between deeply creative and merely inventive genius. Poe's was of the latter sort. He possessed a wild, arbitrary imagination, that sometimes leaped frantically high; but his impressiveness is always that of a nightmare, always completely morbid. What we know of Poe's life leads inevitably to the conclusion that this quality, if it did not spring from disease, was at least largely owing to it. For a time, it was the fashion to make a moral question of Poe's unfortunate obliquities; but a more humane tendency reduces it to a scientific problem.
