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

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!

The brain has not explained the mind fully.

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

The problem of neurology is to understand man himself.

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.

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