As I have said so many times, God doesn't play dice with the world.

Where the world ceases to be the scene of our personal hopes and wishes, where we face it as free beings admiring, asking and observing, there we enter the realm of Art and Science.

Insofar as we may at all claim that slavery has been abolished today, we owe its abolition to the practical consequences of science

I cannot then believe in this concept of an anthropomorphic God who has the powers of interfering with these natural laws. As I said before, the most beautiful and most profound religious emotion that we can experience is the sensation of the mystical. And this mysticality is the power of all true science.

Creative energy is more critical than learning.

When I was still a rather precocious young man, I already realized most vividly the futility of the hopes and aspirations that most men pursue throughout their lives.

There is one ray of hope. It seems to me that today the responsible leaders of the several peoples have, in the main, the honest will to abolish war.
