A piece that Harold Bloom introduced me to -- it was included in a book of his:  Ralph Waldo Emerson's definition, or vision, of poetry and its powers:

If the imagination intoxicates the poet, it is not inactive in other men. The metamorphosis excites in the beholder an emotion of joy. The use of symbols has a certain power of emancipation and exhilaration for all men. We seem to be touched by a wand, which makes us dance and run about happily, like children. We are like persons who come out of a cave or cellar into the open air. This is the effect on us of tropes, fables, oracles, and all poetic forms. Poets are thus liberating gods. Men have really got a new sense, and found within their world, another world, or nest of worlds; for, the metamorphosis once seen, we divine that it does not stop...   [W]hen Orpheus speaks of hoariness as "that white flower which marks extreme old age;" when Proclus calls the universe the statue of the intellect; when Chaucer, in his praise of 'Gentilesse,' compares good blood in mean condition to fire, which, though carried to the darkest house betwixt this and the mount of Caucasus, will yet hold its natural office, and burn as bright as if twenty thousand men did it behold; when John saw, in the Apocalypse, the ruin of the world through evil, and the stars fall from heaven, as the figtree casteth her untimely fruit; when Aesop reports the whole catalogue of common daily relations through the masquerade of birds and beasts; — we take the cheerful hint of the immortality of our essence, and its versatile habit and escapes, as when the gypsies say, "it is in vain to hang them, they cannot die."

This is the first of a series of posts related to writing: the opinions of writers on the process, and their own working and ways, disappointments, glories, etc.
