He had learned well the law of club and fang, and he never forewent an advantage or drew back from a foe he had started on the way to Death. He had lessoned from Spitz, and from the chief fighting dogs of the police and mail, and knew there was no middle course. He must master or be mastered; while to show mercy was a weakness. mercy did not exist in the primordial life. It was misunderstood for fear, and such misunderstandings made for death. Kill or be killed, eat or be eaten, was the law; and this mandate, down out of the depths of Time, he obeyed.
Jack London[Speaking to a group of wealthy New Yorkers] A million years ago, the cave man, without tools, with small brain, and with nothing but the strength of his body, managed to feed his wife and children, so that through him the race survived. You on the other hand, armed with all the modern means of production, multiplying the productive capacity of the cave man a million times — you are incompetents and muddlers, you are unable to secure to millions even the paltry amount of bread that would sustain their physical life. You have mismanaged the world, and it shall be taken from you.
Jack LondonA good soldier is a blind, heartless, soulless, murderous machine. He is not a man. His is not a brute, for brutes kill only in self defense. All that is human in him, all that is divine in him, all that constitutes the man has been sworn away when he took the enlistment roll. His mind, his conscience, aye, his very soul, are in the keeping of his officer. No man can fall lower than a soldier-it is a depth beneath which we cannot go.
