“Study changes a man, puts pride into him. You need it to get to the bottom of life. Without it you just skim the surface. You think you're in the know, but trifles throw you off. You dream too much. You content yourself with words instead of going deeper. That's not what you wanted. Intentions, appearances, no more. A man of character can't content himself with that. Medicine, even if I wasn't very gifted, had brought me a good deal closer to people, to animals, everything. Now all I had to do was plunge straight into the heart of things. Death is chasing you, you've got to hurry, and while you're looking you've got to eat, and keep away from wars. That's a lot of things to do. It's no picnic.”
