“Because mankind can circumvent evolutionary law, it is incumbent upon him, say evolutionary biologists to develop another law to abide by if he wishes to survive, to not outstrip his food base. He must learn restraint. He must derive some other, wiser way of behaving toward the land. He must be more attentive to the biological imperatives of the system of sun-driven protoplasm upon which he, too, is still dependent. Not because he must, because he lacks inventiveness, but because herein is the accomplishment of the wisdom that for centuries he has aspired to. Having taken on his own destiny, he must now think with critical intelligence about where to defer.”

“Man's mind is his basic tool of survival. Life is given to him, survival is not. His body is given to him, its sustenance is not. His mind is given to him, its content is not. To remain alive, he must act, and before he can act he must know the nature and purpose of his action. He cannot obtain his food without a knowledge of food and of the way to obtain it. He cannot dig a ditch-or build a cyclotron-without a knowledge of his aim and of the means to achieve it. To remain alive, he must think”

“Mankind is focused on earth; he is mostly interested in stupid things like wars or ideological absurdities. What he has to do is to concentrate on the universe, because the universe is a cosmic novel that he must read fully, that he must understand fully and that in the end he must rewrite it!”

“All this is a preface to the fear and uncertainties which clamber over a man so that in his silly work he thinks he must be crazy because he is so alone.”

“The stronger must dominate and not mate with the weaker, which would signify the sacrifice of its own higher nature. Only the born weakling can look upon this principle as cruel, and if he does so it is merely because he is of a feebler nature and narrower mind; for if such a law did not direct the process of evolution then the higher development of organic life would not be conceivable at all.”

“He must trust, and he must have faith. And so he builds, because what is building, and rebuilding and rebuilding again, but an act of faith?”
