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

“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.” [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. “Sometimes one feels, even when one is reading poets of a better time–Tennyson or Wordsworth, let us say–that they have troubled the energy and simplicity of their imaginative passions by asking whether they were for the helping or for the hindrance of the world, instead of believing that all beautiful things have ‘lain burningly on the Divine hand.'”
  3. “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.”
  4. “if a powerful and benevolent spirit has shaped the destiny of this world, we can better discover that destiny from the words that have gathered up the heart’s desire of the world, than from historical records, or from speculation, wherein the heart withers.”
  5. “He had learned from Jacob Boehme and from old alchemist writers that imagination was the first emanation of divinity, ‘the body of God,’ ‘the Divine members,’ and he drew the deduction, which they did not draw, that the imaginative arts were therefore the greatest of Divine revelations, and that the sympathy with all living things, sinful and righteous alike, which the imaginative arts awaken, is that forgiveness of sins commanded by Christ.”
