The brain is the organ of destiny. It holds within its humming mechanism secrets that will determine the future of the human race.

Among the millions of nerve cells that clothe parts of the brain there runs a thread. It is the thread of time, the thread that has run through each succeeding wakeful hour of the individual.

Rest, with nothing else, results in rust. It corrodes the mechanisms of the brain. The rhubarb that no one picks goes to seed.

It is fair to say that science provides no method of controlling the mind. Scientific work on the brain does not explain the mind-not yet.

I realized that there was a thrilling undiscovered country to be explored in the mechanisms of the mammalian nervous system. Through it, one might approach the mystery of the mind.

In spite of all these disquieting triumphs in the field of natural science, it's astonishing how little man has learned about himself, and how much there is to learn. How little we know about this brain which made social evolution possible, and of the mind. How little we know of the nature and spirit of man and God. We stand now before this inner frontier of ignorance. If we could pass it, we might well discover the meaning of life and understand man's destiny.
