Each enriched the other's nature. Olivier had serenity of mind and a sickly body. Christophe had mighty strength and a stormy soul. They were in some sort like a blind man and a cripple. Now that they were together they felt sound and strong. Living in the shadow of Christophe Olivier recovered his joy in the light: Christophe transmitted to him something of his abounding vitality, his physical and moral robustness, which, even in sorrow, even in injustice, even in hate, inclined to optimism. He took much more than he gave, in obedience to the law of genius, which gives in vain, but in love always takes more than it gives, _quia nominor leo_, because it is genius, and genius half consists in the instinctive absorption of all that is great in its surroundings and making it greater still. The vulgar saying has it that riches go to the rich. Strength goes to the strong. Christophe fed on Olivier's ideas: he impregnated himself with his intellectual calmness and mental detachment, his lofty outlook, his silent understanding and mastery of things. But when they were transplanted into him, the richer soil, the virtues of his friend grew with a new and other energy. They both marveled at the things they discovered in each other. There were so many things to share! Each brought vast treasures of which till then he had never been conscious: the moral treasure of his nation: Olivier the wide culture and the psychological genius of France: Christophe the innate music of Germany and his intuitive knowledge of nature. Christophe could not understand how Olivier could be a Frenchman. His friend was so little like all the Frenchmen he had met! Before he found Olivier he had not been far from taking Lucien Lévy-Coeur as the type of the modern French mind, Lévy-Coeur who was no more than the caricature of it. And now through Olivier he saw that there might be in Paris minds just as free, more free indeed than that of Lucien Lévy-Coeur, men who remained as pure and stoical as any in Europe. Christophe tried to prove to Olivier that he and his sister could not be altogether French. "My poor dear fellow," said Olivier, "what do you know of France?" Christophe avowed the trouble he had taken to gain some knowledge of the country: he drew up a list of all the Frenchmen he had met in the circle of the Stevens and the Roussins: Jews, Belgians, Luxemburgers, Americans, Russians, Levantines, and here and there a few authentic Frenchmen. "Just what I was saying," replied Olivier. "You haven't seen a single Frenchman. A group of debauchees, a few beasts of pleasure, who are not even French, men-about-town, politicians, useless creatures, all the fuss and flummery which passes over and above the life of the nation without even touching it. You have only seen the swarms of wasps attracted by a fine autumn and the rich meadows. You haven't noticed the busy hives, the industrious city, the thirst for knowledge."
