Personally, I experience the greatest degree of pleasure in having contact with works of art. They furnish me with happy feelings of an intensity that I cannot derive from other sources.

The fairest thing we can experience is the mysterious. It is the fundamental emotion that stands at the cradle of true art and true science. It is the source of all true art and science. He who knows it not and can no longer wonder, no longer feel amazement, is as good as dead, a snuffed-out candle.

The stakes are immense, the task colossal, the time is short. But we may hope - we must hope - that man's own creation, man's own genius, will not destroy him.

It has often been said, and certainly not without justification, that the man of science is a poor philosopher.

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

I appeal to all men and women, whether they be eminent or humble, to declare that they will refuse to give any further assistance to war or the preparation of war.

Know where to find the information and how to use it - That's the secret of success.
