The dignity of man is vindicated as much by the thinker and poet as by the statesman and soldier.

There is only one proved method of assisting the advancement of pure science-that of picking men of genius, backing them heavily, and leaving them to direct themselves.

Science emerges from the other progressive activities of man to the extent that new concepts arise from experiments and observations, and that the new concepts in turn lead to further experiments and observations.

Whether a man lives or dies in vain can be measured only by the way he faces his own problems, by the success or failure of the inner conflict within his own soul. And of this no one may know save God.
