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.
And of poetry, the success is not attained when it lulls and satisfies, but when it astonishes and fires us with new endeavours after the unattainable.
The tragic element in poetry is like Saturn in alchemy, the Malevolent, the Destroyer of Nature ; but without it no true Aurum Potabile, or Elixir of Life, can be made.
The poet's mind is in fact a receptacle for seizing and storing up numberless feelings, phrases, images, which remain there until all the particles which can unite to form a new compound are present together.
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.
