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

“He affirms again and again that the virtuous, those who have ‘pure desire and universal love,’ are happy in the midst of tyranny, and he foresees a day when ‘the spirit of nature,’ the spirit of beauty of his later poems, who has her ‘throne of power unappealable in every human heart,’ shall have made men so virtuous that ‘kingly glare will lose its power to dazzle and silently pass by,’ and as it seems even commerce, ‘the venal interchange of all that human art or nature yields, which wealth should purchase not,’ come as silently to an end.” [via]
