Atoms are weird stuff, behaving like active agents rather than inert substances. They make unpredictable choices between alternative possibilities according to the laws of quantum mechanics. It appears that mind, as manifested by the capacity to make choices, is to some extent inherent in every atom. The universe is also weird, with its laws of nature that make it hospitable to the growth of mind. I do not make any clear distinction between mind and God. God is what mind becomes when it passes beyond the scale of our comprehension.

You have this world of mathematics, which is very real and which contains all kinds of wonderful stuff. And then we also have the world of nature, which is real, too. And that, by some miracle, the language that nature speaks is the same language that we invented for mathematics. That's just an amazing piece of luck, which we don't understand.

Computer models of the climate....[are] a very dubious business if you don't have good inputs.

If the tools are bad, nature's voice is muffled. If the tools are good, nature will give us a clear answer to a clear question.

For any speculation which does not at first glance look crazy, there is no hope.

It's better to get mugged than to live a life of fear.

If you don't have a nasty obituary you probably didn't matter.
