The later 18th-century novel, preoccupied with the understanding of the tensions and dangers of a society about to wake up to the Revolution of 1789—the Great Revolution to which the modern French state traces its origins—is dominated by the masterpiece of Pierre Choderlos de Laclos, Les Liaisons dangereuses (1782; Dangerous Acquaintances), and its stylish account of erotic psychology and its manipulations. The libertine Valmont and his accomplice and rival, Mme de Merteuil, plot the downfall of their victims in a Parisian society that illustrates Rousseau’s strictures: natural human values have no place in a world of conformist expediency, cynicism, and vicious exploitation. Laclos’s novel is, he claims, didactic, a moral satire of a dangerous, heartless world; yet he also admires the cold, vengeful intelligence that invents and directs that world’s viciousness, which the highly crafted epistolary construction of the work, as well as its elegant, sharp-witted, and subtle language, brilliantly exemplify.

By contrast, Jacques-Henri Bernardin de Saint-Pierre’s utopian Paul et Virginie (1788; Paul and Virginia), a rich evocation of exotic nature in the tropical setting of Mauritius, often seems overly sentimental to modern tastes. Another, very different, follower of Rousseauist ideals, the verbose and prolific Nicolas-Edme Restif de la Bretonne, became the self-proclaimed chronicler and analyst of Parisian society, a representative young man of the generation that had gone from country to city in search of fresh fortune. In his philosophical treatises, novels, and short-story collections, he evoked vividly the manners and morals of men and especially women, in all their social ranks, from the bourgeois mistress of the house to the prostitutes in the street. Along with the work of Louis-Sébastien Mercier, author of Le Tableau de Paris (1781–89; Panorama of Paris [selections]), his evocations of the life and movement of the burgeoning metropolis prepare the ground for Honoré de Balzac’s analyses of its human, social, and political dramas. A very different response to this time of radical change came from Donatien-Alphonse-François, comte de Sade, generally known as the Marquis de Sade, whose fascination with the connections of power, pain, and pleasure, between individuals and in society’s larger structures, gave rise to the word sadism. In Sade’s philosophy, where the essential operation of Nature is not procreation but destruction, murder is natural and morally acceptable. The true libertine must replace soft sentiment by an energy aspiring to the total freedom of individual desire. The language and thematics of Sade’s fantasies owe much to the Enlightenment, of which his antisocial egoism is, however, only a perverted expression. But in works such as Justine; ou, les malheurs de la vertu (1791; Justine; or, The Misfortunes of Virtue) or the tale of Justine’s sister, Juliette (1797; Eng. trans. Juliette), he made the reader aware as never before that the search for fulfillment in the enjoyment of cruelty forms part of the human psyche. The text he wrote in the Bastille, never published in his lifetime, Les 120 Journées de Sodome (written 1784–85, published 1904; The 120 Days of Sodom, and Other Writings), has, since the studies of the Surrealists and Georges Bataille, become a classic sourcebook for the study of the imaginative forms of the modern unconscious.
