I enjoy being at a meeting that doesn't start with an invocation!

Maybe nature is fundamentally ugly, chaotic and complicated. But if it's like that, then I want out.

Even though their arguments did not invoke religion, I think we all know what's behind these arguments. They're trying to protect religious beliefs from contradiction by science. They used to do it by prohibiting teachers from teaching evolution at all; then they wanted to teach intelligent design as an alternative theory; now they want the supposed "weaknesses" in evolution pointed out. But it's all the same program - it's all an attempt to let religious ideas determine what is taught in science courses.

If there is no solace in the fruits of our research, there is at least some consolation in the research itself. Men and women are not content to comfort themselves with tales of gods and giants, or to confine their thoughts to the daily affairs of life; they also build telescopes and satellites and accelerators and sit at their desks for endless hours working out the meaning of the data they gather.

I now want to tell three stories about advances in twentieth-century physics. A curious fact emerges in these tales: time and again physicists have been guided by their sense of beauty not only in developing new theories but even in judging the validity of physical theories once they are developed. Simplicity is part of what I mean by beauty, but it is a simplicity of ideas, not simplicity of a mechanical sort that can be measured by counting equations or symbols.

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

I think enormous harm is done by religion - not just in the name of religion, but actually by religion. ... Many people do simply awful things out of sincere religious belief, not using religion as a cover the way that Saddam Hussein may have done, but really because they believe that this is what God wants them to do, going all the way back to Abraham being willing to sacrifice Isaac because God told him to do that. Putting God ahead of humanity is a terrible thing.
