"We never learn anything, never in the world, and in spite of all the history books written. They're just the way we plead or argue with ourselves about it, but it's only light from the outside that we're supposed to take inside. If we can. There's a regular warehouse of fine suggestions and if we're not better it isn't because there aren't plenty of marvellous and true ideas to draw on, but because our vanity weighs more than all of them put together."
The Adventures of Augie March, Saul Bellow
