“He became quicker of movement than the other dogs, swifter of foot, craftier, deadlier, more lithe, more lean with ironlike muscle and sinew, more enduring, more cruel more ferocious, and more intelligent. He had to become all these things, else he would not have held his own nor survived the hostile environment in which he found himself.”

“They were his environment, these men, and they were moulding the clay of him into a more ferocious thing than had been intended by Nature. Nevertheless, Nature had given him plasticity. Where many another animal would have died or had its spirit broken, he adjusted himself and lived, and at no expense of the spirit.”

“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.”

“Do you know the only value life has is what life puts upon itself? And it is of course overestimated, for it is of necessity prejudiced in its own favour. Take that man I had aloft. He held on as if he were a precious thing, a treasure beyond diamonds of rubies. To you? No. To me? Not at all. To himself? Yes. But I do not accept his estimate. He sadly overrates himself. There is plenty more life demanding to be born. Had he fallen and dripped his brains upon the deck like honey from the comb, there would have been no loss to the world. The supply is too large.”

“The clay of White Fang had been molded until he became what he was, morose and lonely, unloving and ferocious, the enemy of all his kind.”

“As he piled wood on the fire he discovered an appreciation of his own body which he had never felt before...It fascinated him, and he grew suddenly fond of this subtle flesh of his that worked so beautifully and smoothly and delicately. Then he would cast a glance of fear at the wolf-circle drawn expectantly about him, and like a blow the realization would strike him that this wonderful body of his, this living flesh, was no more than so much meat, a quest of ravenous animals, to be torn and slashed by their hungry fangs, to be sustenance to them as the moose and the rabbit had often been sustenance to him.(Ch.3)”

“At the first step upon the cold surface, Buck's feet sank into a white mushy something very like mud. He sprang back with a snort. More of this white stuff was falling through the air. He shook himself, but more of it fell upon him. He sniffed it curiously, then licked some up on his tongue. It bit like fire, and the next instant was gone. This puzzled him. He tried it again, with the same result. The onlookers laughed uproariously, and he felt ashamed, he knew not why, for it was his first snow.”
