Just want to say I have a quibble with the first quote. I find that one of the most useful things in the world is to find someone or something that agrees with you on 90% of your beliefs and disagrees on the other 10%. I find that this makes it very difficult to dismiss them as idiots (after all, they share the vast majority of my beliefs) and makes me really examine that last 10% to see if I'm perhaps wrong on some of them.
