Julian Barnes said this quote
“ He thought of trying to explain something he had recently noticed about himself: that if anyone insulted him, or one of his friends, he didn't really mind--or not much, anyway. Whereas if anyone insulted a novel, a story, a poem that he loved, something visceral and volcanic occurred within him. He wasn't sure what this might mean--except perhaps that he had got life and art mixed up, back to front, upside down. ”
