The more the universe seems comprehensible, the more it also seems pointless.

If there is no point in the universe that we discover by the methods of science, there is a point that we can give the universe by the way we live, by loving each other, by discovering things about nature, by creating works of art. And that — in a way, although we are not the stars in a cosmic drama, if the only drama we're starring in is one that we are making up as we go along, it is not entirely ignoble that faced with this unloving, impersonal universe we make a little island of warmth and love and science and art for ourselves. That's not an entirely despicable role for us to play.

All logical arguments can be defeated by the simple refusal to reason logically

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.

A theorist today is hardly considered respectable if he or she has not introduced at least one new particle for which there is no experimental evidence.

Its a consequence of the experience of science. As you learn more and more about the universe, you find you can understand more and more without any reference to supernatural intervention, so you lose interest in that possibility. Most scientists I know dont care enough about religion even to call themselves atheists. And that, I think, is one of the great things about science-that it has made it possible for people not to be religious.

Our job in physics is to see things simply, to understand a great many complicated phenomena in a unified way, in terms of a few simple principles.
