A finely tempered nature longs to escape from the personal life into the world of objective perception and thought.

The most incomprehensible thing about the world is that it is comprehensible.

I know not with what weapons World War III will be fought, but World War IV will be fought with sticks and stones.

Physical concepts are free creations of the human mind, and are not, however, it may seem, uniquely determined by the external world.

Now he has departed from this strange world a little ahead of me. That means nothing. People like us, who believe in physics,know that the distinction between past, present, and future is only a stubbornly persistent illusion.

I am enough of an artist to draw freely upon my imagination. Imagination is more important than knowledge. Knowledge is limited. Imagination encircles the world.

I don't try to imagine a God; it suffices to stand in awe of the structure of the world, insofar as it allows our inadequate senses to appreciate it.
