"Shelley lives on outside his verse," writes Isabel Quigly in her masterful introduction to The Penguin Portable Library Shelley. She goes on to quote Byron:
Byron, who was almost entirely uninclined, by nature and habit, for admiration, wrote to Murray: 'You were all brutally mistaken about Shelley, who was, without exception, the BEST and least selfish man I ever knew. I never knew anyone who was not a beast in comparison.'
This goodness, this bonté, should be examined. For Romantic poets, it is almost impossible not to take their life into consideration when discussing their works. And this tells about an essential feature of Romanticism.
