"No one ever reads a book. He reads himself through books, either to discover or to control himself. And the most objective books are the most deceptive. The greatest book is not the one whose message engraves itself on the brain, as a telegraphic message engraves itself on the ticker-tape, but the one whose vital impact opens up other viewpoints, and from writer to reader spreads the fire that is fed by the various essences, until it becomes a vast conflagration leaping from forest to forest."
