Wilder Penfield quotes:

Canadian weather resembles a slightly spoiled beautiful girl with a good heart, but a bad disposition. After being horrid for much too long a time, she suddenly turns right about and makes up for everything with so much charm that you vow again you always loved her!

Brain surgery is a terrible profession. If I did not feel it will become different in my lifetime, I should hate it.

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

The problem of neurology is to understand man himself.

...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...

Although the content of consciousness depends in large measure on neuronal activity, awareness itself does not.To me, it seems more and more reasonable to suggest that the mind may be a distinct and different essence.

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.

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.

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.

Mind, brain, and body make the man, and the man is capable of so much!

My plea to educators and parents is that they should give some thought to the nature of the brain of a child, for the brain is a living mechanism, not a machine. In case of breakdown, it can substitute one of its parts for the function of another. But it has its limitations. It is subject to inexorable change with the passage of time.

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

The brain has not explained the mind fully.
