We should be most careful about retreating from the specific challenge of our age. We should be reluctant to turn our back upon the frontier of this epoch... We cannot be indifferent to space, because the grand slow march of our intelligence has brought us, in our generation, to a point from which we can explore and understand and utilize it.

The master in the art of living makes little distinction between his work and his play, his labor and his leisure, his mind and his body, his information and his recreation, his love and his religion.

I feel myself the inheritor of a great background of people. Just who, precisely, they were, I have never known. I might be part Negro, might be part Jew, part Muslim, part Irish. So I can't afford to be supercilious about any group of people because I may be that people.

And you have to live with it.
