More quotes by Richard Feynman

"Science is what we have learned about how to keep from fooling ourselves."
"We are at the very beginning of time for the human race. It is not unreasonable that we grapple with problems. But there are tens of thousands of years in the future. Our responsibility is to do what we can, learn what we can, improve the solutions, and pass them on."
"Science is like sex: sometimes something useful comes out, but that is not the reason we are doing it."
"The first principle is that you must not fool yourself and you are the easiest person to fool."
"[Quantum mechanics] describes nature as absurd from the point of view of common sense. And yet it fully agrees with experiment. So I hope you can accept nature as She is - absurd."
