Jean-Christophe was impervious to sickness. He had inherited from his father and grandfather their robust constitutions. They were not mollycoddles in that family; well or ill, they never worried, and nothing could bring about any change in the habits of the two Kraffts, father and son. They went out winter and summer, in all weathers, and stayed for hours together out in rain or sun, sometimes bareheaded and with their coats open, from carelessness or bravado, and walked for miles without being tired, and they looked with pity and disdain upon poor Louisa, who never said anything, but had to stop. She would go pale, and her legs would swell, and her heart would thump. Jean-Christophe was not far from sharing the scorn of his mother; he did not understand people being ill. When he fell, or knocked himself, or cut himself, or burned himself, he did not cry; but he was angry with the thing that had injured him. His father's brutalities and the roughness of his little playmates, the urchins of the street, with whom he used to fight, hardened him. He was not afraid of blows, and more than once he returned home with bleeding nose and bruised forehead. One day he had to be wrenched away, almost suffocated, from one of these fierce tussles in which he had bowled over his adversary, who was savagely banging his head on the ground. That seemed natural enough to him, for he was prepared to do unto others as they did unto himself. And yet he was afraid of all sorts of things, and although no one knew it--for he was very proud--nothing brought him go much suffering during a part of his childhood as these same terrors. For two or three years especially they gnawed at him like a disease. He was afraid of the mysterious something that lurks in darkness--evil powers that seemed to lie in wait for his life, the roaring of monsters which fearfully haunt the mind of every child and appear in everything that he sees, the relic perhaps of a form long dead, hallucinations of the first days after emerging from chaos, from the fearful slumber in his mother's womb, from the awakening of the larva from the depths of matter. He was afraid of the garret door. It opened on to the stairs, and was almost always ajar. When he had to pass it he felt his heart heating; he would spring forward and jump by it without looking. It seemed to him that there was some one or something behind it. When it was closed he heard distinctly something moving behind it. That was not surprising, for there were large rats; but he imagined a monster, with rattling bones, and flesh hanging in rags, a horse's head, horrible and terrifying eyes, shapeless. He did not want to think of it, but did so in spite of himself. With trembling hand he would make sure that the door was locked; but that did not keep him from turning round ten times as he went downstairs.
