Scientists are explorers. Philosophers are tourists.

[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.

Start out understanding religion by saying everything is possibly wrong... As soon as you do that, you start sliding down an edge which is hard to recover from.

I don't think that the laws can be considered to be like God because they have been figured out.

The shell game that we play ... is technically called 'renormalization'. But no matter how clever the word, it is still what I would call a dippy process! Having to resort to such hocus-pocus has prevented us from proving that the theory of quantum electrodynamics is mathematically self-consistent. It's surprising that the theory still hasn't been proved self-consistent one way or the other by now; I suspect that renormalization is not mathematically legitimate.

An ordinary fool isn't a faker; an honest fool is all right. But a dishonest fool is terrible!

Doubt is clearly a value in science. It is important to doubt and that the doubt is not a fearful thing, but a thing of great value.
