Unless science is controlled by a greater moral force, it will become the Antichrist prophesied by the early Christians.

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

If one took no chances, one would not fly at all. Safety lies in the judgment of the chances one takes.

Science, freedom, beauty, adventure: what more could you ask of life?

The improvement of our way of life is more important than the spreading of it. If we make it satisfactory enough, it will spread automatically. If we do not, no strength of arms can permanently oppose it.

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.

Life without risks is not worth living.
