These are the fruits of the "fine frenzy" which he ascribes to the poet,--a fine frenzy doubtless, but still a frenzy. Truth, indeed, is essential to poetry; but it is the truth of madness. The reasonings are just; but the premises are false. After the first suppositions have been made, everything ought to be consistent; but those first suppositions require a degree of credulity which almost amounts to a partial and temporary derangement of the intellect. Hence of all people children are the most imaginative. They abandon themselves without reserve to every illusion. Every image which is strongly presented to their mental eye produces on them the effect of reality. No man, whatever his sensibility may be, is ever affected by Hamlet or Lear, as a little girl is affected by the story of poor Red Riding-hood. She knows that it is all false, that wolves cannot speak, that there are no wolves in England. Yet in spite of her knowledge she believes; she weeps; she trembles; she dares not go into a dark room lest she should feel the teeth of the monster at her throat. Such is the despotism of the imagination over uncultivated minds. In a rude state of society men are children with a greater variety of ideas. It is therefore in such a state of society that we may expect to find the poetical temperament in its highest perfection. In an enlightened age there will be much intelligence, much science, much philosophy, abundance of just classification and subtle analysis, abundance of wit and eloquence, abundance of verses, and even of good ones; but little poetry. Men will judge and compare; but they will not create. They will talk about the old poets, and comment on them, and to a certain degree enjoy them. But they will scarcely be able to conceive the effect which poetry produced on their ruder ancestors, the agony, the ecstasy, the plenitude of belief. The Greek Rhapsodists, according to Plato, could scarce recite Homer without falling into convulsions. The Mohawk hardly feels the scalping knife while he shouts his death-song. The power which the ancient bards of Wales and Germany exercised over their auditors seems to modern readers almost miraculous. Such feelings are very rare in a civilised community, and most rare among those who participate most in its improvements. They linger longest among the peasantry. Poetry produces an illusion on the eye of the mind, as a magic lantern produces an illusion on the eye of the body. And, as the magic lantern acts best in a dark room, poetry effects its purpose most completely in a dark age. As the light of knowledge breaks in upon its exhibitions, as the outlines of certainty become more and more definite, and the shades of probability more and more distinct, the hues and lineaments of the phantoms which the poet calls up grow fainter and fainter. We cannot unite the incompatible advantages of reality and deception, the clear discernment of truth and the exquisite enjoyment of fiction.
