A few words, however, in explanation. That pleasure which is at once the most pure, the most elevating, and the most intense, is derived, I maintain, from the contemplation of the Beautiful. In the contemplation of Beauty we alone find it possible to attain that pleasurable elevation, or excitement of the soul, which we recognize as the Poetic Sentiment, and which is so easily distinguished from Truth, which is the satisfaction of the Reason, or from Passion, which is the excitement of the heart. I make Beauty, therefore—using the word as inclusive of the sublime—I make Beauty the province of the poem, simply because it is an obvious rule of Art that effects should be made to spring as directly as possible from their causes:—no one as yet having been weak enough to deny that the peculiar elevation in question is at least most readily attainable in the poem. It by no means follows, however, that the incitements of Passion, or the precepts of Duty, or even the lessons of Truth, may not be introduced into a poem, and with advantage; for they may subserve incidentally, in various ways, the general purposes of the work: but the true artist will always contrive to tone them down in proper subjection to that Beauty which is the atmosphere and the real essence of the poem.
