The more we refine our understanding of God to make the concept plausible, the more it seems pointless.

Anything that we scientists can do to weaken the hold of religion, should be done and may, in fact, in the end, be our greatest contribution to civilization.

The universe is an enormous direct product of representations of symmetry groups.

My advice is to go for the messes - that's where the action is.

It was one time when people thought the value of the fine structure constant was important. Now of course it's still important, of course, as a practical matter,but we now know that the value it has is a function, that in any fundamental theory you derive the fine structure constant as a function of all sorts of mass ratios and so on and it's not really that fundamental.

As for me, I have just enough confidence about the multiverse to bet the lives of both Andrei Linde and Martin Rees’s dog.

You know, our fundamentalist friends dislike the teaching of evolution in schools because of the effect they feel it has on our view of our own special importance, while liberals insist that scientific and spiritual matters can be kept in separate compartments. On this point, I tend to agree with the fundamentalists, though I come to opposite conclusions about teaching evolution because I am convinced it's true.
