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.

My father had been opposed to my flying from the first and had never flown himself. However, he had agreed to go up with me at the first opportunity, and one afternoon he climbed into the cockpit and we flew over the Redwood Falls together. From that day on I never heard a word against my flying and he never missed a chance to ride in the plane.

Then what am I - the body substance which I can see with my eyes and feel with my hands? Or am I this realization, this greater understanding which dwells within it, yet expands through the universe outside; a part of all existence, powerless but without need for power; immersed in solitude, yet in contact with all creation? There are moments when the two appear inseparable, and others when they could be cut apart by the merest flash of light.

The remedy for our social evils does not consist so much in changing the system of government as it does in increasing the general intelligence of the people so that they may learn how to govern.

I know there is infinity beyond ourselves. I wonder if there is infinity within.

Man must feel the earth to know himself and recognize his values. God made life simple. It is man who complicates it.

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.
