One could almost phrase the motto of our modern civilization thus: Science is my shepherd; I shall not want.

No man need stay the way he is.

[L]ife ceases to be a fraction and becomes an integer.

God is not a cosmic bellboy for whom we can press a button to get things.

He who knows no hardships will know no hardihood. He who faces no calamity will need no courage. Mysterious though it is, the characteristics in human nature which we love best grow in a soil with a strong mixture of troubles.

One must have the adventurous daring to accept oneself as a bundle of possibilities and undertake the most interesting game in the world -- making the most of one's best.

Democracy is not simply a political system; it is a moral movement and it springs from adventurous faith in human possibilities.
