William Blake and the Imagination in Ideas of Good and Evil by William Butler Yeats.

“He cried again and again that every thing that lives is holy, and that nothing is unholy except things that do not live—lethargies, and cruelties, and timidities, and that denial of imagination which is the root they grew from in old times.” [via]

Consider also:

  1. “In our time we are agreed that we ‘make our souls’ out of some one of the great poets of ancient times, or out of Shelley or Wordsworth, or Goethe or Balzac, or Flaubert, or Count Tolstoy, in the books he wrote before he became a prophet and fell into a lesser order, or out of Mr. Whistler’s pictures, while we amuse ourselves, or, at best, make a poorer sort of soul, by listening to sermons or by doing or by not doing certain things.”
  2. “The technique of Blake was imperfect, incomplete, as is the technique of well-nigh all artists who have striven to bring fires from remote summits; but where his imagination is perfect and complete, his technique has a like perfection, a like completeness.”
  3. “The reason, and by the reason he meant deductions from the observations of the senses, binds us to mortality because it binds us to the senses, and divides us from each other by showing us our clashing interests; but imagination divides us from mortality by the immortality of beauty, and binds us to each other by opening the secret doors of all hearts.”
  4. “Blake represented the shapes of beauty haunting our moments of inspiration: shapes held by most for the frailest of ephemera, but by him for a people older than the world, citizens of eternity, appearing and reappearing in the minds of artists and of poets, creating all we touch and see by casting distorted images of themselves upon ‘the vegetable glass of nature’; and because beings, none the less symbols, blossoms, as it were, growing from invisible immortal roots, hands, as it were, pointing the way into some divine labyrinth.”
  5. “Living in a time when technique and imagination are continually perfect and complete, because they no longer strive to bring fire from heaven, we forget how imperfect and incomplete they were in even the greatest masters”
