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

“in the Ode to Liberty, Liberty is bid lead wisdom out of the inmost cave of man’s mind as the Morning Star leads the sun out of the waves.” [via]

Consider also:

  1. “Cythna in the passage where she speaks of making signs ‘a subtle language within language’ on the sand by the ‘fountain’ of sea water in the cave where she is imprisoned, speaks of the ‘cave’ of her mind which gave its secrets to her, and of ‘one mind the type of all’ which is a ‘moveless wave’ reflecting ‘all moveless things that are'”
  2. “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.”
  3. “It may be that his subconscious life seized upon some passing scene, and moulded it into an ancient symbol without help from anything but that great memory; but so good a Platonist as Shelley could hardly have thought of any cave as a symbol, without thinking of Plato’s cave that was the world; and so good a scholar may well have had Porphyry on ‘the Cave of the Nymphs’ in his mind.”
  4. “He calls the spirit of beauty liberty, because despotism, and perhaps, as ‘the man of virtuous soul commands not nor obeys,’ all authority, pluck virtue from her path towards beauty, and because it leads us by that love whose service is perfect freedom.”
  5. “The most important, the most precise of all Shelley’s symbols, the one he uses with the fullest knowledge of its meaning, is the Morning and Evening Star. It rises and sets for ever over the towers and rivers, and is the throne of his genius.”
