He had come to know quite thoroughly the world in which he lived. His outlook was bleak and materialistic. The world as he saw it was a fierce and brutal world, a world without warmth, a world in which caresses and affection and the bright sweetness of spirit did not exist.
The first theft marked Buck as fit to survive in the hostile Northland environment. It marked his adaptability, his capacity to adjust himself to changing conditions, the lack of which would have meant swift and terrible death. It marked, further, the decay or going to pieces of his moral nature, a vain thing and a handicap in the ruthless struggle for existence.
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.
He was a killer, a thing that preyed, living on the things that lived, unaided, alone, by virtue of his own strength and prowess, surviving triumphantly in a hostile environment where only the strong survive.
But nobody else ever romped with White Fang. He did not permit it. He stood on his dignity, and when they attempted it, his warning snarl and bristling mane were anything but playful. That he allowed the master these liberties was no reason that he should be a common dog, loving here and loving there, everybody's property for a romp and good time. He loved with single heart and refused to cheapen himself or his love.
I early learned that there were two natures in me. This caused me a great deal of trouble, till I worked out a philosophy of life and struck a compromise between the flesh and the spirit. Too great an ascendancy of either was to be abnormal, and since normality is almost a fetish of mine, I finally succeeded in balancing both natures. Ordinarily they are at equilibrium; yet as frequently as one is permitted to run rampant, so is the other. I have small regard for an utter brute or for an utter saint.
Love cannot in its very nature be peaceful or content. It is a restlessness, an unsatisfaction. I can grant a lasting love just as I can grant a lasting unsatisfaction; but the lasting love cannot be coupled with possession, for love is pain and desire and possession is easement and fulfilment.
And not only did he learn by experience, but instincts long dead became alive again. The domesticated generations fell from him. In vague ways he remembered back to the youth of the breed, to the time the wild dogs ranged in packs through the primeval forest and killed their meat as they ran it down.
Food and fire, protection and companionship, were some of the things he received from the god. In return, he guarded the god's property, defended his body, worked for him, and obeyed him.
[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.
