Without the sense of fellowship with men of like mind, of preoccupation with the objective, the eternally unattainable in the field of art and scientific research, life would have seemed to me empty.

In the midst of every crisis, lies great opportunity.

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.

Arrows of hate have been aimed at me too, but they have never hit me, because somehow they belonged to another world with which I have no connection whatsoever.

Once you can accept the universe as matter expanding into nothing that is something, wearing stripes with plaid comes easy.

An expert is a person who has few new ideas; a beginner is a person with many.

Do not grow old, no matter how long you live. Never cease to stand like curious children before the Great Mystery into which we were born.
