Though aware that there is nothing in the universe that suggests any purpose for humanity, one way that we can find a purpose is to study the universe by the methods of science, without consoling ourselves with fairy tales about its future, or about our own.

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.

It is even harder to realize that this present universe has evolved from an unspeakably unfamiliar early condition, and faces a future extinction of endless cold or intolerable heat. The more the universe seems comprehensible, the more it seems pointless.

Any possible universe could be explained as the work of some sort of designer. Even a universe that is completely chaotic...could be supposed to have been designed by an idiot.

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

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

As you learn more and more about the irrelevance of human life to the general mechanism of the universe, the idea of an interested god, becomes increasingly implausible.
