This is one of the great social functions of science - to free people from superstition

In our universe we are tuned into the frequency that corresponds to physical reality. But there are an infinite number of parallel realities coexisting with us in the same room, although we cannot tune into them.

The invisible and the non-existent look very much alike.

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.

If history is any guide at all, it seems to me to suggest that there is a final theory. In this century we have seen a convergence of the arrows of explanation, like the convergence of meridians toward the North Pole.

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.

Our mistake is not that we take our theories too seriously, but that we do not take them seriously enough.
