I believe that present day civilized man suffers from insufficient discharge of his aggressive drive

The human mind, in taking us down the path of technocracy, has become the adversary of life itself and collaterally the adversary of the human soul.

The distance at which all shooting weapons take effect screens the killer against the stimulus sensation which would otherwise activate his killing inhibitions. The deep, emotional layers of our personality simply do not register the fact that the crooking of the finger to release a shot tears the entrails of another man.

I am convinced that of all the people on the two sides of the great curtain, the space pilots are the least likely to hate each other. Like the late Erich von Holst, I believe that the tremendous and otherwise not quite explicable public interest in space flight arises from the subconscious realization that it helps to preserve peace. May it continue to do so!

Barking dogs may occasionally bite, but laughing men hardly ever shoot!

Man has been driven out of the paradise in which he could trust his instincts.

The fidelity of a dog is a precious gift.
