Quote from the book "The Call of the Wild"

He was beaten (he knew that); but he was not broken. He saw, once for all, that he stood no chance against a man with a club. He had learned the lesson, and in all his after life he never forgot it. That club was a revelation. It was his introduction to the reign of primitive law, and he met the introduction halfway. The facts of life took on a fiercer aspect and, while he faced that aspect uncowed, he faced it with all the latent cunning of his nature aroused.
