By this time it was nine o'clock; Lucien followed the example set in secret by his future friend by asking him to dine at Eldon's, and spent twelve francs at that restaurant. During the dinner Daniel admitted Lucien into the secret of his hopes and studies. Daniel d'Arthez would not allow that any writer could attain to a pre-eminent rank without a profound knowledge of metaphysics. He was engaged in ransacking the spoils of ancient and modern philosophy, and in the assimilation of it all; he would be like Moliere, a profound philosopher first, and a writer of comedies afterwards. He was studying the world of books and the living world about him--thought and fact. His friends were learned naturalists, young doctors of medicine, political writers and artists, a number of earnest students full of promise. D'Arthez earned a living by conscientious and ill-paid work; he wrote articles for encyclopaedias, dictionaries of biography and natural science, doing just enough to enable him to live while he followed his own bent, and neither more nor less. He had a piece of imaginative work on hand, undertaken solely for the sake of studying the resources of language, an important psychological study in the form of a novel, unfinished as yet, for d'Arthez took it up or laid it down as the humor took him, and kept it for days of great distress. D'Arthez's revelations of himself were made very simply, but to Lucien he seemed like an intellectual giant; and by eleven o'clock, when they left the restaurant, he began to feel a sudden, warm friendship for this nature, unconscious of its loftiness, this unostentatious worth. Lucien took d'Arthez's advice unquestioningly, and followed it out to the letter. The most magnificent palaces of fancy had been suddenly flung open to him by a nobly-gifted mind, matured already by thought and critical examinations undertaken for their own sake, not for publication, but for the solitary thinker's own satisfaction. The burning coal had been laid on the lips of the poet of Angouleme, a word uttered by a hard student in Paris had fallen upon ground prepared to receive it in the provincial. Lucien set about recasting his work. In his gladness at finding in the wilderness of Paris a nature abounding in generous and sympathetic feeling, the distinguished provincial did, as all young creatures hungering for affection are wont to do; he fastened, like a chronic disease, upon this one friend that he had found. He called for D'Arthez on his way to the Bibliotheque, walked with him on fine days in the Luxembourg Gardens, and went with his friend every evening as far as the door of his lodging-house after sitting next to him at Flicoteaux's. He pressed close to his friend's side as a soldier might keep by a comrade on the frozen Russian plains.
