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

“Some old magical writer, I forget who, says if you wish to be melancholy hold in your left hand an image of the Moon made out of silver, and if you wish to be happy hold in your right hand an image of the Sun made out of gold.” [via]

Consider also:

  1. “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.”
  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. “I have re-read Prometheus Unbound, which I had hoped my fellow-students would have studied as a sacred book, and it seems to me to have an even more certain place than I had thought, among the sacred books of the world.”
  5. “In ancient times, it seems to me that Blake, who for all his protest was glad to be alive, and ever spoke of his gladness, would have worshipped in some chapel of the Sun, and that Keats, who accepted life gladly though ‘with a delicious diligent indolence,’ would have worshipped in some chapel of the Moon, but that Shelley, who hated life because he sought ‘more in life than any understood,’ would have wandered, lost in a ceaseless reverie, in some chapel of the Star of infinite desire.”
