“Don't you believe in flying saucers, they ask me? Don't you believe in telepathy? — in ancient astronauts? — in the Bermuda triangle? — in life after death?No, I reply. No, no, no, no, and again no.One person recently, goaded into desperation by the litany of unrelieved negation, burst out "Don't you believe in anything?"Yes", I said. "I believe in evidence. I believe in observation, measurement, and reasoning, confirmed by independent observers. I'll believe anything, no matter how wild and ridiculous, if there is evidence for it. The wilder and more ridiculous something is, however, the firmer and more solid the evidence will have to be.”

“Does everyone just believe what he wants to?""As long as possible. Sometimes longer.""What about you?""You mean, am I human? Certainly. I don't believe I'm really old. I believe I'm quite attractive. I believe you seek out my company because you think I'm charming - even when you insist on turning the conversation to physics.”

“I don't believe in an afterlife, so I don't have to spend my whole life fearing hell, or fearing heaven even more. For whatever the tortures of hell, I think the boredom of heaven would be even worse.”

“Grip the nettle firmly and it will become a stick with which to beat your enemy.”
