“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.”

“But it did not all happen in a day, this giving over of himself, body and soul, to the man-animals. He could not immediately forego his wild heritage and his memories of the Wild. There were days when he crept to the edge of the forest and stood and listened to something calling him far and away.”

“I cannot help remembering a remark of De Casseres. It was over the wine in Mouquin's. Said he: "The profoundest instinct in man is to war against the truth; that is, against the Real. He shuns facts from his infancy. His life is a perpetual evasion. Miracle, chimera and to-morrow keep him alive. He lives on fiction and myth. It is the Lie that makes him free. Animals alone are given the privilege of lifting the veil of Isis; men dare not. The animal, awake, has no fictional escape from the Real because he has no imagination. Man, awake, is compelled to seek a perpetual escape into Hope, Belief, Fable, Art, God, Socialism, Immortality, Alcohol, Love. From Medusa-Truth he makes an appeal to Maya-Lie”

“This man had saved his life, which was something; but, further, he was the ideal master. Other men saw to the welfare of their dogs from a sense of duty and business expediency; he saw to the welfare of his as if they were his own children, because he could not help it. And he saw further. He never forgot a kindly greeting or a cheering word, and to sit down for a long talk with them ("gas" he called it) was as much his delight as theirs. He had a way of taking Buck's head roughly between his hands, and resting his own head upon Buck's, of shaking him back and forth, the while calling him ill names that to Buck were love names. Buck knew no greater joy than that rough embrace and the sound of murmured oaths, and at each jerk back and forth it seemed that his heart would be shaken out of his body so great was its ecstasy. And when, released, he sprang to his feet, his mouth laughing, his eyes eloquent, his throat vibrant with unuttered sound, and in that fashion remained without movement, John Thornton would reverently exclaim, "God! you can all but speak!"Buck had a trick of love expression that was akin to hurt. He would often seize Thornton's hand in his mouth and close so fiercely that the flesh bore the impress of his teeth for some time afterward. And as Buck understood the oaths to be love words, so the man understood this feigned bite for a caress.”

“On the sled, in the box, lay a third man whose toil was over, - a man whom the Wild had conquered and beaten down until he would never move nor struggle again. It is not the way of the Wild to like movement. Life is an offense to it, for life is movement; and the Wild aims always to destroy movement.”

“In this manner had fought forgotten ancestors. They quickened the old life within him, the old tricks which they had stamped into the heredity of the breed were his tricks... And when, on the still cold nights, he pointed his nose at a star and howled long and wolflike, it was his ancestors, dead and dust, pointing nose at star and howling down through the centuries and through him.”

“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.”
