Ideas are like seeds, apparently insignificant when first held in the hand. Once firmly planted, they can grow and flower into almost anything at all, a cornstalk, or a giant redwood, or a flight across the ocean. Whatever a man imagines, he can achieve.

Success is not measured by what a man accomplishes, but by the opposition he has encountered and the courage with which he has maintained the struggle against overwhelming odds.

As civilization advances, man grows unconscious of the primitive elements of life; he is separated from them by his perfection of material techniques.

I believe that for permanent survival, man must balance science with other qualities of life, qualities of body and spirit as well as those of mind - qualities he cannot develop when he lets mechanics and luxury insulate him too greatly from the earth to which he was born.

If we can combine our knowledge of science with the wisdom of wildness, if we can nurture civilization through roots in the primitive, man's potentialities appear to be unbounded.

Whatever a man imagines he can attain, if he doesn't become too arrogant and encroach on the rights of the gods.

The idea of racial inferiority or superiority is foreign to me. I can't feel inferior or superior to another man because of race, or in any way antagonistic to him. I judge by the individual, not by his race, and have always done so. I would rather have one of my children marry into a good family of any race than into a bad family of any other race.
