That critical discernment is not sufficient to make men poets, is generally allowed. Why it should keep them from becoming poets, is not perhaps equally evident; but the fact is, that poetry requires not an examining but a believing frame of mind. Those feel it most, and write it best, who forget that it is a work of art; to whom its imitations, like the realities from which they are taken, are subjects, not for connoisseurship, but for tears and laughter, resentment and affection; who are too much under the influence of the illusion to admire the genius which has produced it; who are too much frightened for Ulysses in the cave of Polyphemus to care whether the pun about Outis be good or bad; who forget that such a person as Shakspeare ever existed, while they weep and curse with Lear. It is by giving faith to the creations of the imagination that a man becomes a poet. It is by treating those creations as deceptions, and by resolving them, as nearly as possible, into their elements, that he becomes a critic. In the moment in which the skill of the artist is perceived, the spell of the art is broken. These considerations account for the absurdities into which the greatest writers have fallen, when they have attempted to give general rules for composition, or to pronounce judgment on the works of others. They are unaccustomed to analyse what they feel; they, therefore, perpetually refer their emotions to causes which have not in the slightest degree tended to produce them. They feel pleasure in reading a book. They never consider that this pleasure may be the effect of ideas which some unmeaning expression, striking on the first link of a chain of associations, may have called up in their own minds--that they have themselves furnished to the author the beauties which they admire.
