II. His Ruling Symbols from The Philosophy of Shelley’s Poetry in Ideas of Good and Evil by William Butler Yeats.

“It is only by ancient symbols, by symbols that have numberless meanings beside the one or two the writer lays an emphasis upon, or the half-score he knows of, that any highly subjective art can escape from the barrenness and shallowness of a too conscious arrangement, into the abundance and depth of nature.” [via]

Consider also:

  1. “His early romances and much throughout his poetry show how strong a fascination the traditions of magic and of the magical philosophy had cast over his mind, and one can hardly suppose that he had not brooded over their doctrine of symbols or signatures, though I do not find anything to show that he gave it any deep study.”
  2. “It may have been this memory, or it may have been some impulse of his nature too subtle for his mind to follow, that made Keats, with his love of embodied things, of precision of form and colouring, of emotions made sleepy by the flesh, see Intellectual Beauty in the Moon; and Blake, who lived in that energy he called eternal delight, see it in the Sun, where his personification of poetic genius labours at a furnace.”
  3. “I think this mysterious song utters a faith as simple and as ancient as the faith of those country people, in a form suited to a new age, that will understand, with Blake, that the holy spirit is ‘an intellectual fountain,’ and that the kinds and degrees of beauty are the images of its authority.”
  4. “our little memories are but a part of some great memory that renews the world and men’s thoughts age after age, and that our thoughts are not, as we suppose, the deep but a little foam upon the deep.”
  5. “Again and again one finds some passing allusion to the cave of man’s mind, or to the caves of his youth, or to the cave of mysteries we enter at death, for to Shelley as to Porphyry it is more than an image of life in the world.”
