For true poetry, complete poetry, consists in the harmony of contraries. Hence, it is time to say aloud--and it is here above allthat exceptions prove the rule--that everything that exists in nature exists in art.
Good poetry could not have been otherwise written than it is. The first time you hear it, it sounds rather as if copied out of some invisible tablet in the Eternal mind than as if arbitrarily composed by the poet.
Not only every great poet, but every genuine, but lesser poet, fulfils once for all some possibility of language, and so leaves one possibility less for his successors.
I have said that poetry is the spontaneous overflow of powerful feelings: it takes its origin from emotion recollected in tranquillity: the emotion is contemplated till, by a species of reaction, the tranquillity gradually disappears, and an emotion, kindred to that which was before the subject of contemplation, is gradually produced, and does itself actually exist in the mind.
I take as metaphysical poetry that in which what is ordinarily apprehensible only by thought is brought within the grasp of feeling, or that in which what is ordinarily only felt is transformed into thought without ceasing to be feeling.
It is clear that a poem may be improperly brief. Undue brevity degenerates into mere epigrammatism. A very short poem, while now and then producing a brilliant or vivid, never produces a profound or enduring, effect. There must be the steady pressing down of the stamp upon the wax.
The philosophic mind inclines always to an elaborate life--the life of Goethe or of Leonardo da Vinci; but the life of the poet isintense--the life of Blake or of Dante--taking into its centre the life that surrounds it and flinging it abroad again amid planetary music.
