Why is Jean-Jacques Rousseau famous?Jean-Jacques Rousseau is famous for reconceiving the social contract as a compact between the individual and a collective “general will” aimed at the common good and reflected in the laws of an ideal state and for maintaining that existing society rests on a false social contract that perpetuates inequality and rule by the rich.
Jean-Jacques Rousseau (born June 28, 1712, Geneva, Switzerland—died July 2, 1778, Ermenonville, France) was a Swiss-born philosopher, writer, and political theorist whose treatises and novels inspired the leaders of the French Revolution and the Romantic generation.
Rousseau was the least academic of modern philosophers and in many ways was the most influential. His thought marked the end of the European Enlightenment (the “Age of Reason”). He propelled political and ethical thinking into new channels. His reforms revolutionized taste, first in music, then in the other arts. He had a profound impact on people’s way of life; he taught parents to take a new interest in their children and to educate them differently; he furthered the expression of emotion rather than polite restraint in friendship and love. He introduced the cult of religious sentiment among people who had discarded religious dogma. He opened people’s eyes to the beauties of nature, and he made liberty an object of almost universal aspiration.
Rousseau’s mother died in childbirth, and he was brought up by his father, who taught him to believe that the city of his birth was a republic as splendid as Sparta or ancient Rome. Rousseau senior had an equally glorious image of his own importance; after marrying above his modest station as a watchmaker, he got into trouble with the civil authorities by brandishing the sword that his upper-class pretentions prompted him to wear, and he had to leave Geneva to avoid imprisonment. Rousseau, the son, then lived for six years as a poor relation in his mother’s family, patronized and humiliated, until he, too, at the age of 16, fled from Geneva to live the life of an adventurer and a Roman Catholic convert in the kingdoms of Sardinia and France.
Rousseau was fortunate in finding in the province of Savoy a benefactor, the baroness de Warens, who provided him with a refuge in her home and employed him as her steward. She also furthered his education to such a degree that the boy who had arrived on her doorstep as a stammering apprentice who had never been to school developed into a philosopher, a scholar, and a musician.
Britannica Quiz Philosophy 101Mme de Warens, who thus transformed the adventurer into a philosopher, was herself an adventuress—a Swiss convert to Catholicism who had stripped her husband of his money before fleeing to Savoy with the gardener’s son to set herself up as a Catholic missionary specializing in the conversion of young male Protestants. Her morals distressed Rousseau, even when he became her lover. But she was a woman of taste, intelligence, and energy, who brought out in Rousseau just the talents that were needed to conquer Paris at a time when Voltaire had made radical ideas fashionable.
Rousseau reached Paris when he was 30 and was lucky enough to meet another young man from the provinces seeking literary fame in the capital, Denis Diderot. The two soon became immensely successful as the centre of a group of intellectuals—or philosophes—who gathered round the great French Encyclopédie, of which Diderot was appointed editor. The Encyclopédie was an important organ of radical and anticlerical opinion, and its contributors were as much reforming and even iconoclastic pamphleteers as they were philosophers. Rousseau, the most original of them all in his thinking and the most forceful and eloquent in his style of writing, was soon also the most conspicuous. He wrote music as well as prose, and one of his operas, Le Devin du village (1752; “The Village Soothsayer”), attracted so much admiration from the king (Louis XV) and the court that he might have enjoyed an easy life as a fashionable composer, but something in his Calvinist blood rejected that type of worldly glory. Indeed, at the age of 37 Rousseau had what he called an “illumination” while walking to Vincennes to visit Diderot, who had been imprisoned there because of his irreligious writings. In the Confessions (1782–89), which he wrote late in life, Rousseau says that it came to him then in a “terrible flash” that modern progress had corrupted people instead of improving them. He went on to write his first important work, a prize essay for the Academy of Dijon entitled Discours sur les sciences et les arts (1750; A Discourse on the Sciences and the Arts), in which he argues that the history of human life on earth has been a history of decay.
That work is by no means Rousseau’s best piece of writing, but its central theme was to inform almost everything else he wrote. Throughout his life he kept returning to the thought that people are good by nature but have been corrupted by society and civilization. He did not mean to suggest that society and civilization are inherently bad but rather that both had taken a wrong direction and become more harmful as they became more sophisticated. That idea in itself was not unfamiliar in Rousseau’s time. Many Roman Catholic writers, for example, deplored the direction that European culture had taken since the Middle Ages. They shared the hostility toward progress that Rousseau had expressed. What they did not share was his belief that people are naturally good. It was, however, just that belief that Rousseau made the cornerstone of his argument.
Rousseau may well have received the inspiration for that belief from Mme de Warens; for although she had become a communicant of the Roman Catholic Church, she retained—and transmitted to Rousseau—much of the sentimental optimism about human purity that she had herself absorbed as a child from the mystical Protestant Pietists who were her teachers in the canton of Bern. At all events, the idea of human goodness, as Rousseau developed it, set him apart from both conservatives and radicals. Even so, for several years after the publication of A Discourse on the Sciences and the Arts—conventionally referred to as the First Discourse, he remained a close collaborator in Diderot’s essentially progressive enterprise, the Encyclopédie, and an active contributor to its pages. His speciality there was music, and it was in this sphere that he first established his influence as a reformer.
The arrival of an Italian opera company in Paris in 1752 to perform works of opera buffa (comic opera) by Giovanni Battista Pergolesi, Alessandro Scarlatti, Leonardo Vinci, and other such composers suddenly divided the French music-loving public into two excited camps, supporters of the new Italian opera and supporters of the traditional French opera. The philosophes of the Encyclopédie—Jean Le Rond d’Alembert, Diderot, and Paul-Henri Dietrich, baron d’Holbach among them—entered the fray as champions of Italian music, but Rousseau, who had arranged for the publication of Pergolesi’s music in Paris and who knew more about the subject than most Frenchmen after the months he had spent visiting the opera houses of Venice during his time as secretary to the French ambassador to the doge in 1743–44, emerged as the most-forceful and effective combatant. He was the only one to direct his fire squarely at the leading living exponent of French operatic music, Jean-Philippe Rameau.
Rousseau and Rameau must at that time have seemed unevenly matched in a controversy about music. Rameau, already in his 70th year, was not only a prolific and successful composer but was also, as the author of the celebrated Traité de l’harmonie (1722; Treatise on Harmony) and other technical works, Europe’s leading musicologist. Rousseau, by contrast, was 30 years younger, a newcomer to music, with no professional training and only one successful opera to his credit. His scheme for a new notation for music had been rejected by the Academy of Sciences, and most of his musical entries for Diderot’s Encyclopédie were as yet unpublished. Yet the dispute was not only musical but also philosophical, and Rameau was confronted with a more-formidable adversary than he had realized. Rousseau built his case for the superiority of Italian music over French on the principle that melody must have priority over harmony, whereas Rameau based his on the assertion that harmony must have priority over melody. By pleading for melody, Rousseau introduced what later came to be recognized as a characteristic idea of Romanticism, namely, that in art the free expression of the creative spirit is more important than strict adherence to formal rules and traditional procedures. By pleading for harmony, Rameau reaffirmed the first principle of French Classicism, namely, that conformity to rationally intelligible rules is a necessary condition of art, the aim of which is to impose order on the chaos of human experience.
In music, Rousseau was a liberator. He argued for freedom in music, and he pointed to the Italian composers as models to be followed. In doing so he had more success than Rameau; he changed people’s attitudes. Christoph Willibald Gluck, who succeeded Rameau as the most-important operatic composer in France, acknowledged his debt to Rousseau’s teaching, and Wolfgang Amadeus Mozart based the text for his one-act operetta Bastien und Bastienne (Bastien and Bastienne) on Rousseau’s Le Devin du village. European music had taken a new direction. But Rousseau himself composed no more operas. Despite the success of Le Devin du village, or rather because of its success, Rousseau felt that, as a moralist who had decided to make a break with worldly values, he could not allow himself to go on working for the theatre. He decided to devote his energies henceforth to literature and philosophy.
