He brought the same eager, impressionable spirit to his novels and stories. It is indeed no great step from “Le Rêve de d’Alembert” to “Le Neveu de Rameau,” and from that to “La Religieuse.” Whatever he undertook he carried out with the whole energy and enthusiasm of his nature, and while this takes from the artistic symmetry of his work, it adds to its vitality and significance. It is owing to this quality that “Les Bijoux Indiscrets,” a frivolous novel in the style of the younger Crebillon, pointless and indecent, written, at the age of thirty-five, mainly to obtain money for his mistress, Mme. de Puisieux, contains passages which have been considered among the finest he ever wrote, and by its reflections on the reform of the theatre, its criticisms of manners, and philosophical insight served avowedly as the point of departure for Lessing’s famous “Dramaturgie.” It was not until he read Richardson that Diderot produced any very noteworthy work in fiction; his admiration for the English novelist was extreme, but certainly not out of proportion to Richardson’s historic importance. Richardson not only marks the first real landmark in the evolution of the English novel; he is the point of departure of the modern French novel, and Diderot, more than any one else, helped to make his influence felt in France. Very soon after falling under the spell of the great English story-teller and writing his “Éloge de Richardson,” Diderot produced his most famous novel, “La Religieuse.” It is clear how much Richardson influenced this minute study, in autobiographic form, of the life and sufferings of a young girl forced into a convent with its uncongenial atmosphere and petty persecutions. It was a distinct artistic achievement, the more remarkable as it was certainly intended as an attack on the small vices of a community of women isolated from the world. Even those parts of this attack which have been considered questionable are always in the tone of the unsuspecting young girl who writes them, and only become offensive when a modern editor removes them in order to substitute asterisks; compare these passages with the more ostentatious propriety and zeal for virtue of a modern Parisian in “Mademoiselle Giraud ma Femme.” A year later Diderot wrote an unquestionable artistic masterpiece, only preserved for us by a happy chance, “Le Neveu de Rameau,” a dialogue of unfailing spirit between himself and a strange social parasite whom he is analyzing. Some years later he fell under the influence of Sterne; “Jacques le Fataliste,” so attractive to Goethe and many others, was the result. But he had no great affinity for the sinuous humour of Sterne, and, while he threw himself into it with his usual energy, the result, though Shandean enough, is less happy than his great Richardsonian effort. Yet “Jacques le Fataliste” contains the “Histoire de Mme. de la Pommeraye,” and this little _histoire_, when disentangled from the manifold episodes which interrupt the hostess of the inn who tells it, is Diderot’s most perfect and most characteristic effort as a story-teller. Even in his novels it is the directness and the veracity of his scientific spirit, united to his emotional impressionability, which gives significance to his work.
