"When he was made, the mould was broke," said Pete. - Jack London

He was justifying his existence, than which life can do no greater; for life achieves its summit when it does to the uttermost that which it was equipped to do.

His muscles had wasted away to knotty strings, and the flesh pads had disappeared, so that each rib and every bone in his frame were outlined cleanly through the loose hide that was wrinkled in folds of emptiness. It was heartbreaking, only Buck's heart was unbreakable. The man in the red sweater had proved that.

It was just such uniqueness of points of view that startled Ruth. Not only were they new to her, and contrary to her own beliefs, but she always felt in them germs of truth that threatened to unseat or modify her own convictions. Had she been fourteen instead of twenty-four, she might have been changed by them; but she was twenty-four, conservative by nature and upbringing, and already crystallized into the cranny of life where she had been born and formed. It was true, his bizarre judgments troubled her in the moments they were uttered, but she ascribed them to his novelty of type and strangeness of living, and they were soon forgotten. Nevertheless, while she disapproved of them, the strength of their utterance, and the flashing of eyes and earnestness of face that accompanied them, always thrilled her and drew her toward him. She would never have guessed that this man who had come from beyond her horizon, was, in such moments, flashing on beyond her horizon with wider and deeper concepts. Her own limits were the limits of her horizon; but limited minds can recognize limitations only in others. And so she felt that her outlook was very wide indeed, and that where his conflicted with hers marked his limitations; and she dreamed of helping him to see as she saw, of widening his horizon until it was identified with hers.
