That is the way of the scientist. He will spend thirty years in building up a mountain range of facts with the intent to prove a certain theory; then he is so happy with his achievement that as a rule he overlooks the main chief fact of all-that all his accumulation proves an entirely different thing.
Mark TwainEvolution is a blind giant who rolls a snowball down a hill. The ball is made of flakes-circumstances. They contribute to the mass without knowing it. They adhere without intention, and without foreseeing what is to result. When they see the result they marvel at the monster ball and wonder how the contriving of it came to be originally thought out and planned. Whereas there was no such planning, there was only a law: the ball once started, all the circumstances that happened to lie in its path would help to build it, in spite of themselves.

Mark TwainThe Bible is full of interest. It has noble poetry in it; and some clever fables; and some blood-drenched history; and some good morals; and a wealth of obscenity; and upwards of a thousand lies. This Bible is built mainly out of fragments of older Bibles that had their day and crumbled to ruin. So it noticeably lacks in originality, necessarily. Its three or four most imposing and impressive events all happened in earlier Bibles; there are only two new things in it: hell, for one, and that singular heaven I have told you about.
