“In dim ways he recognized in man the animal that had fought itself to primacy over the other animals of the Wild. Not alone out of his own eyes, but out of the eyes of all his ancestors was the cub now looking upon man.”

“We talk of wild animals but man is the only wild animal. It is man that has broken out. All other animals are tame animals; following the rugged respectability of the tribe or type.”

“Obstacles are like wild animals. They are cowards but they will bluff you if they can. If they see you are afraid of them...they are liable to spring upon you; but if you look them squarely in the eye, they will slink out of sight.”
