To die is poignantly bitter, but the idea of having to die without having lived is unbearable.

I feel worried, deeply worried, only about one thing - the possibility that we fall... that we cannot avoid an atomic war.

Whether...a change from the supremacy of natural science to a new social science will take place...depends on one factor: how many brilliant, learned, disciplined, and caring men and women are attracted by the new challenge.

Sleep is often the only occasion in which man cannot silence his conscience; we forget what we knew in our dream.

Most people die before they are fully born. Creativeness means to be born before one dies.

The paradoxical and tragic situation of man is that his conscience is weakest when he needs it most.

I believe that man is the product of natural evolution that is born from the conflict of being a prisoner and separated from nature, and from the need to find unity and harmony with it.
