The concept was also an important aspect of the more radical 17th-century republican tradition of Spinoza, from whom Rousseau differed in important respects, but not in his insistence on the importance of equality:

He and his older brother François were brought up by their father and a paternal aunt, also named Suzanne. When Rousseau was five, his father sold the house that the family had received from his mother's relatives. While the idea was that his sons would inherit the principal when grown up and he would live off the interest in the meantime, in the end the father took most of the substantial proceeds. With the selling of the house, the Rousseau family moved out of the upper-class neighborhood and moved into an apartment house in a neighborhood of craftsmen—silversmiths, engravers, and other watchmakers. Growing up around craftsmen, Rousseau would later contrast them favorably to those who produced more aesthetic works, writing "those important persons who are called artists rather than artisans, work solely for the idle and rich, and put an arbitrary price on their baubles". Rousseau was also exposed to class politics in this environment, as the artisans often agitated in a campaign of resistance against the privileged class running Geneva.

Rousseau's reading of escapist stories (such as L'Astrée by Honoré d'Urfé) had an effect on him; he later wrote that they "gave me bizarre and romantic notions of human life, which experience and reflection have never been able to cure me of". After they had finished reading the novels, they began to read a collection of ancient and modern classics left by his mother's uncle. Of these, his favorite was Plutarch's Lives of the Noble Greeks and Romans, which he would read to his father while he made watches. Rousseau saw Plutarch's work as another kind of novel—the noble actions of heroes—and he would act out the deeds of the characters he was reading about.

After Rousseau's Emile had outraged the French parliament, an arrest order was issued by parliament against him, causing him to flee to Switzerland. Subsequently, when the Swiss authorities also proved unsympathetic to him—condemning both Emile, and also The Social Contract—Voltaire issued an invitation to Rousseau to come and reside with him, commenting that: "I shall always love the author of the 'Vicaire savoyard' whatever he has done, and whatever he may do...Let him come here [to Ferney]! He must come! I shall receive him with open arms. He shall be master here more than I. I shall treat him like my own son."

Since Rousseau was keen to relocate to a more remote location, Richard Davenport—a wealthy and elderly widower who spoke French—offered to accommodate Thérèse and Rousseau at Wootton Hall. On 22 March, Rousseau and Therese set forth for Wootton, against Hume's advice. Hume and Rousseau would never meet again. Initially Rousseau was pleased with his new accommodation at Wootton Hall, and wrote favorably about the natural beauty of the place, and how he was feeling reborn, forgetting past sorrows.

When Hume learnt that Rousseau was writing the Confessions, he assumed that the present dispute would feature in the book. Adam Smith, Turgot, Marischal Keith, Horace Walpole, and Mme de Boufflers advised Hume not to make his quarrel with Rousseau public; however, many members of D'Holbach's Coterie—particularly, d'Alembert—urged him to reveal his version of the events. In October 1766, Hume's version of the quarrel was translated into French and published in France; in November it was published in England. Grimm included it in his correspondance; ultimately,

In Paris, Rousseau and Therese lodged in an unfashionable neighborhood of the city, the Rue Platrière—now called the Rue Jean-Jacques Rousseau. He now supported himself financially by copying music, and continued his study of botany. At this time also, he wrote his Letters on the Elements of Botany. These consisted of a series of letters Rousseau wrote to Mme Delessert in Lyon to help her daughters learn the subject. These letters received widespread acclaim when they were eventually published posthumously. "It's a true pedagogical model, and it complements Emile," commented Goethe.

In contrast to the optimistic view of other Enlightenment figures, for Rousseau, progress has been inimical to the well-being of humanity, that is, unless it can be counteracted by the cultivation of civic morality and duty. Only in civil society can man be ennobled—through the use of reason:

Rousseau opposed the idea that the people should exercise sovereignty via a representative assembly (Book III, Chapter XV). He approved the kind of republican government of the city-state, for which Geneva provided a model—or would have done if renewed on Rousseau's principles. France could not meet Rousseau's criterion of an ideal state because it was too big. Much subsequent controversy about Rousseau's work has hinged on disagreements concerning his claims that citizens constrained to obey the general will are thereby rendered free:

In the 18th century, many deists viewed God merely as an abstract and impersonal creator of the universe, likened to a giant machine. Rousseau's deism differed from the usual kind in its emotionality. He saw the presence of God in the creation as good, and separate from the harmful influence of society. Rousseau's attribution of a spiritual value to the beauty of nature anticipates the attitudes of 19th-century Romanticism towards nature and religion. (Historians—notably William Everdell, Graeme Garrard, and Darrin McMahon—have additionally situated Rousseau within the Counter-Enlightenment.) Rousseau was upset that his deism was so forcefully condemned, while those of the more atheistic philosophers were ignored. He defended himself against critics of his religious views in his "Letter to Mgr de Beaumont, the Archbishop of Paris", "in which he insists that freedom of discussion in religious matters is essentially more religious than the attempt to impose belief by force."

The model man is the independent farmer, free of superiors and self-governing. This was cause enough for the philosophes' hatred of their former friend. Rousseau's unforgivable crime was his rejection of the graces and luxuries of civilized existence. Voltaire had sung "The superfluous, that most necessary thing." For the high bourgeois standard of living Rousseau would substitute the middling peasant's. It was the country versus the city—an exasperating idea for them, as was the amazing fact that every new work of Rousseau's was a huge success, whether the subject was politics, theater, education, religion, or a novel about love.

Bastiat believed that Rousseau wished to ignore forms of social order created by the people—viewing them as a thoughtless mass to be shaped by philosophers. Bastiat, who is considered by thinkers associated with the Austrian School of Economics to be one of the precursors of the "spontaneous order", presented his own vision of what he considered to be the "Natural Order" in a simple economic chain in which multiple parties might interact without necessarily even knowing each other, cooperating and fulfilling each other's needs in accordance with basic economic laws such as supply and demand. In such a chain, in order to produce clothing, multiple parties have to act independently—e.g. farmers to fertilize and cultivate land to produce fodder for the sheep, people to shear them, transport the wool, turn it into cloth, and another to tailor and sell it. Those persons engage in economic exchange by nature, and don't need to be ordered to, nor do their efforts need to be centrally coordinated. Such chains are present in every branch of human activity, in which individuals produce or exchange goods and services, and together, naturally create a complex social order that does not require external inspiration, central coordination of efforts, or bureaucratic control to benefit society as a whole. This, according to Bastiat, is a proof that humanity itself is capable of creating a complex socioeconomic order that might be superior to an arbitrary vision of a philosopher.

How did it come about that a man born poor, losing his mother at birth and soon deserted by his father, afflicted with a painful and humiliating disease, left to wander for twelve years among alien cities and conflicting faiths, repudiated by society and civilization, repudiating Voltaire, Diderot, the Encyclopédie and the Age of Reason, driven from place to place as a dangerous rebel, suspected of crime and insanity, and seeing, in his last months, the apotheosis of his greatest enemy—how did it come about that this man, after his death, triumphed over Voltaire, revived religion, transformed education, elevated the morals of France, inspired the Romantic movement and the French Revolution, influenced the philosophy of Kant and Schopenhauer, the plays of Schiller, the novels of Goethe, the poems of Wordsworth, Byron, and Shelley, the socialism of Marx, the ethics of Tolstoy, and, altogether, had more effect upon posterity than any other writer or thinker of that eighteenth century in which writers were more influential than they had ever been before?

Rousseau's ideas have influenced progressive "child-centered" education. John Darling's 1994 book Child-Centered Education and its Critics portrays the history of modern educational theory as a series of footnotes to Rousseau, a development he regards as bad. Good or bad, the theories of educators such as Rousseau's near contemporaries Pestalozzi, Mme. de Genlis and, later, Maria Montessori and John Dewey, which have directly influenced modern educational practices, do have significant points in common with those of Rousseau.

During the Cold War, Rousseau was criticized for his association with nationalism and its attendant abuses, for example in Talmon, Jacob Leib (1952), The Origins of Totalitarian Democracy . This came to be known among scholars as the "totalitarian thesis". Political scientist J.S. Maloy states that "the twentieth century added Nazism and Stalinism to Jacobinism on the list of horrors for which Rousseau could be blamed. […] Rousseau was considered to have advocated just the sort of invasive tampering with human nature which the totalitarian regimes of mid-century had tried to instantiate." But he adds that "The totalitarian thesis in Rousseau studies has, by now, been discredited as an attribution of real historical influence." Arthur Melzer, however, while conceding that Rousseau would not have approved of modern nationalism, observes that his theories do contain the "seeds of nationalism", insofar as they set forth the "politics of identification", which are rooted in sympathetic emotion. Melzer also believes that in admitting that people's talents are unequal, Rousseau therefore tacitly condones the tyranny of the few over the many. Others counter, however, that Rousseau was concerned with the concept of equality under the law, not equality of talents. For Stephen T. Engel, on the other hand, Rousseau's nationalism anticipated modern theories of "imagined communities" that transcend social and religious divisions within states.

In 1919, Irving Babbitt, founder of a movement called the "New Humanism", wrote a critique of what he called "sentimental humanitarianism", for which he blamed Rousseau. Babbitt's depiction of Rousseau was countered in a celebrated and much reprinted essay by A.O. Lovejoy in 1923. In France, fascist theorist Charles Maurras, founder of Action Française, "had no compunctions in laying the blame for both Romantisme et Révolution firmly on Rousseau in 1922."

Ceremonial and symbolic occurrences of the more radical phases of the Revolution invoked Rousseau and his core ideas. Thus the ceremony held at the site of the demolished Bastille, organized by the foremost artistic director of the Revolution, Jacques-Louis David, in August 1793 to mark the inauguration of the new republican constitution, an event coming shortly after the final abolition of all forms of feudal privilege, featured a cantata based on Rousseau's democratic pantheistic deism as expounded in the celebrated "Profession de foi d'un vicaire savoyard" in Book Four of Émile.

Feminists, beginning in the late 18th century with Mary Wollstonecraft in 1792, have criticized Rousseau for his confinement of women to the domestic sphere—unless women were domesticated and constrained by modesty and shame, he feared "men would be tyrannized by women… For, given the ease with which women arouse men's senses—men would finally be their victims…" His contemporaries saw it differently because Rousseau thought that mothers should breastfeed their children. Marmontel wrote that his wife thought, "One must forgive something," she said, "in one who has taught us to be mothers."

The Marquis de Sade's Justine, or the Misfortunes of Virtue (1791) partially parodied and used as inspiration Rousseau's sociological and political concepts in the Discourse on Inequality and The Social Contract. Concepts such as the state of nature, civilization being the catalyst for corruption and evil, and humans "signing" a contract to mutually give up freedoms for the protection of rights, particularly referenced. The Comte de Gernande in Justine, for instance, after Thérèse asks him how he justifies abusing and torturing women, states:

As early as 1788, Madame de Staël published her Letters on the works and character of J.-J. Rousseau. In 1819, in his famous speech "On Ancient and Modern Liberty", the political philosopher Benjamin Constant, a proponent of constitutional monarchy and representative democracy, criticized Rousseau, or rather his more radical followers (specifically the Abbé de Mably), for allegedly believing that "everything should give way to collective will, and that all restrictions on individual rights would be amply compensated by participation in social power."

The German writers Goethe, Schiller, and Herder have stated that Rousseau's writings inspired them. Herder regarded Rousseau to be his "guide", and Schiller compared Rousseau to Socrates. Goethe, in 1787, stated: "Emile and its sentiments had a universal influence on the cultivated mind." The elegance of Rousseau's writing is held to have inspired a significant transformation in French poetry and drama—freeing them from rigid literary norms. Other writers who were influenced by Rousseau's writings included Leopardi in Italy; Pushkin and Tolstoy in Russia; Wordsworth, Southey, Coleridge, Byron, Shelley, and Keats in England; and Hawthorne and Thoreau in America. According to Tolstoy: "At fifteen I carried around my neck, instead of the usual cross, a medallion with Rousseau's portrait."

The first sign of [Rousseau's] political influence was in the wave of public sympathy that supported active French aid to the American Revolution. Jefferson derived the Declaration of Independence from Rousseau as well as from Locke and Montesquieu. As ambassador to France (1785–89) he absorbed much from both Voltaire and Rousseau...The success of the American Revolution raised the prestige of Rousseau's philosophy.

In the spring of 1778, the Marquis Girardin invited Rousseau to live in a cottage in his château at Ermenonville. Rousseau and Thérèse went there on 20 May. Rousseau spent his time at the château in collecting botanical specimens, and teaching botany to Girardin's son. He ordered books from Paris on grasses, mosses and mushrooms, and made plans to complete his unfinished Emile and Sophie and Daphnis and Chloe.

On 4 July 1778, Rousseau was buried on the Île des Peupliers, which became a place of pilgrimage for his many admirers. On 11 October 1794, his remains were moved to the Panthéon, where they were placed near the remains of Voltaire.

In 1777, Rousseau received a royal visitor, when the Holy Roman Emperor Joseph II came to meet him. His free entry to the Opera had been renewed by this time and he would go there occasionally. At this time also (1777–78), he composed one of his finest works, Reveries of a Solitary Walker.

In 1766, Rousseau had impressed Hume with his physical prowess by spending ten hours at night on the deck in severe weather during the journey by ship from Calais to Dover while Hume was confined to his bunk. "When all the seamen were almost frozen to death...he caught no harm...He is one of the most robust men I have ever known," Hume noted. By 1770, Rousseau's urinary disease had also been greatly alleviated after he stopped listening to the advice of doctors. At that time, notes Damrosch, it was often better to let nature take its own course rather than subject oneself to medical procedures. His general health had also improved. However, on 24 October 1776, as he was walking on a narrow street in Paris a nobleman's carriage came rushing by from the opposite direction; flanking the carriage was a galloping Great Dane belonging to the nobleman. Rousseau was unable to dodge both the carriage and the dog, and was knocked down by the Great Dane. He seems to have suffered a concussion and neurological damage. His health began to decline; Rousseau's friend Corancez described the appearance of certain symptoms which indicate that Rousseau started suffering from epileptic seizures after the accident.

In 1772, Rousseau was invited to present recommendations for a new constitution for the Polish–Lithuanian Commonwealth, resulting in the Considerations on the Government of Poland, which was to be his last major political work.

Also in 1772, Rousseau began writing his Dialogues: Rousseau, Judge of Jean-Jacques, which was another attempt to reply to his critics. He completed writing it in 1776. The book is in the form of three dialogues between two characters; a Frenchman and Rousseau who argue about the merits and demerits of a third character—an author called Jean-Jacques. It has been described as his most unreadable work; in the foreword to the book, Rousseau admits that it may be repetitious and disorderly, but he begs the reader's indulgence on the grounds that he needs to defend his reputation from slander before he dies.

After May 1771, there were no more group readings because Madame d'Épinay wrote to the chief of police, who was her friend, to put a stop to Rousseau's readings so as to safeguard her privacy. The police called on Rousseau, who agreed to stop the readings. The Confessions were finally published posthumously in 1782.

In January 1769, Rousseau and Thérèse went to live in a farmhouse near Grenoble. Here he practiced botany and completed the Confessions. At this time he expressed regret for placing his children in an orphanage. On 10 April 1770, Rousseau and Therese left for Lyon where he befriended Horace Coignet, a fabric designer and amateur musician. At Rousseau's suggestion, Coignet composed musical interludes for Rousseau's prose poem Pygmalion; this was performed in Lyon together with Rousseau's romance The Village Soothsayer to public acclaim. On 8 June, Rousseau and Therese left Lyon for Paris; they reached Paris on 24 June.

Around this time, Rousseau started developing feelings of paranoia, anxiety, and of a conspiracy against him. Most of this was just his imagination at work, but on 29 January 1768, the theatre at Geneva was destroyed through burning, and Voltaire mendaciously accused Rousseau of being the culprit. In June 1768, Rousseau left Trie, leaving Therese behind, and went first to Lyon, and subsequently to Bourgoin. He now invited Therese to this place and "married" her under his alias "Renou" in a faux civil ceremony in Bourgoin on 30 August 1768.

After the dispute became public, due in part to comments from notable publishers like Andrew Millar, Walpole told Hume that quarrels such as this only end up becoming a source of amusement for Europe. Diderot took a charitable view of the mess: "I knew these two philosophers well. I could write a play about them that would make you weep, and it would excuse them both." Amidst the controversy surrounding his quarrel with Hume, Rousseau maintained a public silence; but, he resolved now to return to France. To encourage him to do so swiftly, Thérèse advised him that the servants at Wootton Hall sought to poison him. On 22 May 1767, Rousseau and Thérèse embarked from Dover to Calais.

On 22 May 1767, Rousseau reentered France even though an arrest warrant against him was still in place. He had taken an assumed name, but was recognized, and a banquet in his honor was held by the city of Amiens. Many French nobles offered him a residence at this time. Initially, Rousseau decided to stay in an estate near Paris belonging to Mirabeau. Subsequently, on 21 June 1767, he moved to a chateau of the Prince of Conti in Trie.

On 1 January 1766, Grimm wrote a report to his clientele, in which he included a letter said to have been written by Frederick the Great to Rousseau. This letter had actually been composed by Horace Walpole as a playful hoax. Walpole had never met Rousseau, but he was well acquainted with Diderot and Grimm. The letter soon found wide publicity; Hume is believed to have been present, and to have participated in its creation. On 16 February 1766, Hume wrote to the Marquise de Brabantane: "The only pleasantry I permitted myself in connection with the pretended letter of the King of Prussia was made by me at the dinner table of Lord Ossory." This letter was one of the reasons for the later rupture in Hume's relations with Rousseau.

On 4 January 1766, Rousseau left Paris along with Hume, the merchant De Luze, who was an old friend of Rousseau, and Rousseau's pet dog Sultan. After a four-day journey to Calais, where they stayed for two nights, the travelers embarked on a ship to Dover. On 13 January 1766 they arrived in London. Soon after their arrival, David Garrick arranged a box at the Drury Lane Theatre for Hume and Rousseau on a night when the King and Queen were also present. Garrick was himself performing in a comedy by himself, and also a tragedy by Voltaire. Rousseau became so excited during the performance that he leaned too far and almost fell out of the box; Hume observed that the King and Queen were looking at Rousseau more than at the performance. Afterwards, Garrick served supper for Rousseau who commended Garrick's acting: "Sir, you have made me shed tears at your tragedy, and smile at your comedy, though I scarce understood a word of your language."

On 3 April 1766, the letter featuring Horace Walpole's hoax on Rousseau was published in a British daily without mention of Walpole being the actual author; that the editor of the publication was Hume's personal friend compounded Rousseau's grief. Gradually articles critical of Rousseau started appearing in the British press; Rousseau felt that Hume, as his host, ought to have defended him. Moreover, in Rousseau's estimate, some of the public criticism contained details which only Hume was privy to. Further, Rousseau was aggrieved to find that Hume had been lodging in London with François Tronchin, son of Rousseau's enemy in Geneva.

For more than two years (1762–1765) Rousseau lived at Môtiers, spending his time in reading and writing and meeting visitors such as James Boswell (December 1764). In the meantime, the local ministers had become aware of the apostasies in some of his writings, and resolved not to let him stay in the vicinity. The Neuchâtel Consistory summoned Rousseau to answer a charge of blasphemy. He wrote back asking to be excused due to his inability to sit for a long time due to his ailment. Subsequently, Rousseau's own pastor, Frédéric-Guillaume de Montmollin, started denouncing him publicly as the Antichrist. In one inflammatory sermon, Montmollin quoted Proverbs 15:8: "The sacrifice of the wicked is an abomination to the Lord, but the prayer of the upright is his delight"; this was interpreted by everyone to mean that Rousseau's taking communion was detested by the Lord. The ecclesiastical attacks inflamed the parishioners, who proceeded to pelt Rousseau with stones when he would go out for walks. Around midnight of 6–7 September 1765, stones were thrown at the house Rousseau was staying in, and some glass windows were shattered. When a local official, Martinet, arrived at Rousseau's residence he saw so many stones on the balcony that he exclaimed "My God, it's a quarry!" At this point, Rousseau's friends in Môtiers advised him to leave the town.

Since he wanted to remain in Switzerland, Rousseau decided to accept an offer to move to a tiny island, the Ile de St.-Pierre, having a solitary house. Although it was within the Canton of Bern, from where he had been expelled two years previously, he was informally assured that he could move into this island house without fear of arrest, and he did so (10 September 1765). However, on 17 October 1765, the Senate of Bern ordered Rousseau to leave the island and all Bernese territory within fifteen days. He replied, requesting permission to extend his stay, and offered to be incarcerated in any place within their jurisdiction with only a few books in his possession and permission to walk occasionally in a garden while living at his own expense. The Senate's response was to direct Rousseau to leave the island, and all Bernese territory, within twenty four hours. On 29 October 1765 he left the Ile de St.-Pierre and moved to Strasbourg. At this point:

On 9 December 1765, having secured a passport from the French government to come to Paris, Rousseau left Strasbourg for Paris where he arrived after a week, and lodged in a palace of his friend, the Prince of Conti. Here he met Hume, and also numerous friends, and well wishers, and became a very conspicuous figure in the city. At this time, Hume wrote:

For defending his reputation against hostile gossip, Rousseau had begun writing the Confessions in 1765. In November 1770, these were completed, and although he did not wish to publish them at this time, he began to offer group readings of certain portions of the book. Between December 1770, and May 1771, Rousseau made at least four group readings of his book with the final reading lasting seventeen hours. A witness to one of these sessions, Claude Joseph Dorat, wrote:

Rousseau later expressed regret that he had not replied to Voltaire's invitation. In July 1762, after Rousseau was informed that he could not continue to reside in Bern, d'Alembert advised him to move to the Principality of Neuchâtel, ruled by Frederick the Great of Prussia. Subsequently, Rousseau accepted an invitation to reside in Môtiers, fifteen miles from Neuchâtel. On 11 July 1762, Rousseau wrote to Frederick, describing how he had been driven from France, from Geneva, and from Bern; and seeking Frederick's protection. He also mentioned that he had criticized Frederick in the past and would continue to be critical of Frederick in the future, stating however: "Your Majesty may dispose of me as you like." Frederick, still in the middle of the Seven Years' War, then wrote to the local governor of Neuchatel, Marischal Keith who was a mutual friend of theirs:

The Social Contract outlines the basis for a legitimate political order within a framework of classical republicanism. Published in 1762, it became one of the most influential works of political philosophy in the Western tradition. It developed some of the ideas mentioned in an earlier work, the article Économie Politique (Discourse on Political Economy), featured in Diderot's Encyclopédie. The treatise begins with the dramatic opening lines, "Man is born free, and everywhere he is in chains. Those who think themselves the masters of others are indeed greater slaves than they."

His Discourse on Inequality and The Social Contract are cornerstones in modern political and social thought. Rousseau's sentimental novel Julie, or the New Heloise (1761) was important to the development of preromanticism and romanticism in fiction. His Emile, or On Education (1762) is an educational treatise on the place of the individual in society. Rousseau's autobiographical writings—the posthumously published Confessions (composed in 1769), which initiated the modern autobiography, and the unfinished Reveries of a Solitary Walker (composed 1776–1778)—exemplified the late-18th-century "Age of Sensibility", and featured an increased focus on subjectivity and introspection that later characterized modern writing.

Rousseau's 800-page novel of sentiment, Julie, ou la nouvelle Héloïse, was published in 1761 to immense success. The book's rhapsodic descriptions of the natural beauty of the Swiss countryside struck a chord in the public and may have helped spark the subsequent nineteenth-century craze for Alpine scenery. In 1762, Rousseau published Du Contrat Social, Principes du droit politique (in English, literally Of the Social Contract, Principles of Political Right) in April. Even his friend Antoine-Jacques Roustan felt impelled to write a polite rebuttal of the chapter on Civil Religion in the Social Contract, which implied that the concept of a Christian republic was paradoxical since Christianity taught submission rather than participation in public affairs. Rousseau helped Roustan find a publisher for the rebuttal.

One of Rousseau's most important American followers was textbook writer Noah Webster (1758–1843), who was influenced by Rousseau's ideas on pedagogy in Emile (1762). Webster structured his Speller in accord with Rousseau's ideas about the stages of a child's intellectual development.

On returning to Geneva in 1754, Rousseau reconverted to Calvinism and regained his official Genevan citizenship. In 1755, Rousseau completed his second major work, the Discourse on the Origin and Basis of Inequality Among Men (the Discourse on Inequality), which elaborated on the arguments of the Discourse on the Arts and Sciences.

Society corrupts men only insofar as the Social Contract has not de facto succeeded, as we see in contemporary society as described in the Discourse on Inequality (1754). In this essay, which elaborates on the ideas introduced in the Discourse on the Arts and Sciences, Rousseau traces man's social evolution from a primitive state of nature to modern society. The earliest solitary humans possessed a basic drive for self-preservation and a natural disposition to compassion or pity. They differed from animals, however, in their capacity for free will and their potential perfectibility. As they began to live in groups and form clans they also began to experience family love, which Rousseau saw as the source of the greatest happiness known to humanity.

Rousseau continued his interest in music. He wrote both the words and music of his opera Le devin du village (The Village Soothsayer), which was performed for King Louis XV in 1752. The king was so pleased by the work that he offered Rousseau a lifelong pension. To the exasperation of his friends, Rousseau turned down the great honor, bringing him notoriety as "the man who had refused a king's pension". He also turned down several other advantageous offers, sometimes with a brusqueness bordering on truculence that gave offense and caused him problems. The same year, the visit of a troupe of Italian musicians to Paris, and their performance of Giovanni Battista Pergolesi's La serva padrona, prompted the Querelle des Bouffons, which pitted protagonists of French music against supporters of the Italian style. Rousseau as noted above, was an enthusiastic supporter of the Italians against Jean-Philippe Rameau and others, making an important contribution with his Letter on French Music.

Rousseau and Jean-Philippe Rameau argued over the superiority of Italian music over French. Rousseau argued that Italian music was superior based on the principle that melody must have priority over harmony. Rameau argued that Italian music was superior based on the principle that harmony must have priority over melody. Rousseau's plead for melody introduced the idea that in art, the free expression of a creative person is more important than the strict adherence to traditional rules and procedures. This is now known today as a characteristic of Romanticism. Rousseau argued for musical freedom, and changed people's attitudes towards music. His works were acknowledged by composers such as Christoph Willibald Gluck and Wolfgang Amadeus Mozart. After composing The Village Soothsayer in 1752, Rousseau felt he could not go on working for the theater because he was a moralist who had decided to break from worldly values.

Rousseau wrote that he persuaded Thérèse to give each of the newborns up to a foundling hospital, for the sake of her "honor". "Her mother, who feared the inconvenience of a brat, came to my aid, and she [Thérèse] allowed herself to be overcome" (Confessions). In his letter to Madame de Francueil in 1751, he first pretended that he wasn't rich enough to raise his children, but in Book IX of the Confessions he gave the true reasons of his choice: "I trembled at the thought of intrusting them to a family ill brought up, to be still worse educated. The risk of the education of the foundling hospital was much less".

Rousseau had read about an essay competition sponsored by the Académie de Dijon to be published in the Mercure de France on the theme of whether the development of the arts and sciences had been morally beneficial. He wrote that while walking to Vincennes (about three miles from Paris), he had a revelation that the arts and sciences were responsible for the moral degeneration of mankind, who were basically good by nature. Rousseau's 1750 Discourse on the Arts and Sciences was awarded the first prize and gained him significant fame.

Beginning with some articles on music in 1749, Rousseau contributed numerous articles to Diderot and D'Alembert's great Encyclopédie, the most famous of which was an article on political economy written in 1755.

Rousseau's ideas were the result of an almost obsessive dialogue with writers of the past, filtered in many cases through conversations with Diderot. In 1749, Rousseau was paying daily visits to Diderot, who had been thrown into the fortress of Vincennes under a lettre de cachet for opinions in his "Lettre sur les aveugles", that hinted at materialism, a belief in atoms, and natural selection. According to science historian Conway Zirkle, Rousseau saw the concept of natural selection "as an agent for improving the human species."

From 1743 to 1744, Rousseau had an honorable but ill-paying post as a secretary to the Comte de Montaigue, the French ambassador to Venice. This awoke in him a lifelong love for Italian music, particularly opera:

Rousseau befriended fellow philosophy writer Denis Diderot in 1742, and would later write about Diderot's romantic troubles in his Confessions. During the period of the French Revolution, Rousseau was the most popular of the philosophers among members of the Jacobin Club. He was interred as a national hero in the Panthéon in Paris, in 1794, 16 years after his death.

In 1742, Rousseau moved to Paris in order to present the Académie des Sciences with a new system of numbered musical notation he believed would make his fortune. His system, intended to be compatible with typography, is based on a single line, displaying numbers representing intervals between notes and dots and commas indicating rhythmic values. Believing the system was impractical, the Academy rejected it, though they praised his mastery of the subject, and urged him to try again. He befriended Denis Diderot that year, connecting over the discussion of literary endeavors.

Rousseau was a successful composer of music, who wrote seven operas as well as music in other forms, and made contributions to music as a theorist. As a composer, his music was a blend of the late Baroque style and the emergent Classical fashion, and he belongs to the same generation of transitional composers as Christoph Willibald Gluck and C. P. E. Bach. One of his more well-known works is the one-act opera The Village Soothsayer, containing the duet "Non, Colette n'est point trompeuse" which was later rearranged as a standalone song by Beethoven. He also composed several noted motets, some of which were sung at the Concert Spirituel in Paris. Rousseau's Aunt Suzanne was passionate about music and heavily influenced Rousseau's interest in music. In his Confessions, Rousseau claims he is "indebted" to her for his passion of music. Rousseau took formal instruction in music at the house of Francoise-Louise de Warens. She housed Rousseau on and off for about 13 years, giving him jobs and responsibilities. In 1742, Rousseau developed a system of musical notation that was compatible with typography and numbered. He presented his invention to the Academie Des Sciences, but they rejected it, praising his efforts and pushing him to try again. In 1743, Rousseau wrote his first opera, Les Muses galantes [fr] , which was first performed in 1745.

Virtually all our information about Rousseau's youth has come from his posthumously published Confessions, in which the chronology is somewhat confused, though recent scholars have combed the archives for confirming evidence to fill in the blanks. At age 13, Rousseau was apprenticed first to a notary and then to an engraver who beat him. At 15, he ran away from Geneva (on 14 March 1728) after returning to the city and finding the city gates locked due to the curfew.

Jean-Jacques Rousseau (UK: /ˈ r uː s oʊ / , US: /r uː ˈ s oʊ / ; French: [ʒɑ̃ʒak ʁuso] ; 28 June 1712 – 2 July 1778) was a Genevan philosopher, writer and composer. His political philosophy influenced the progress of the Enlightenment throughout Europe, as well as aspects of the French Revolution and the development of modern political, economic and educational thought.

Rousseau was born on 28 June 1712, and he would later relate: "I was born almost dying, they had little hope of saving me". He was baptized on 4 July 1712, in the great cathedral. His mother died of puerperal fever nine days after his birth, which he later described as "the first of my misfortunes".

There was much political debate within Geneva, extending down to the tradespeople. Much discussion was over the idea of the sovereignty of the people, of which the ruling class oligarchy was making a mockery. In 1707, a democratic reformer named Pierre Fatio protested this situation, saying "a sovereign that never performs an act of sovereignty is an imaginary being". He was shot by order of the Little Council. Jean-Jacques Rousseau's father, Isaac, was not in the city at this time, but Jean-Jacques's grandfather supported Fatio and was penalized for it.

In 1699, Isaac ran into political difficulty by entering a quarrel with visiting English officers, who in response drew their swords and threatened him. After local officials stepped in, it was Isaac who was punished, as Geneva was concerned with maintaining its ties to foreign powers.

Rousseau's mother, Suzanne Bernard Rousseau, was from an upper-class family. She was raised by her uncle Samuel Bernard, a Calvinist preacher. He cared for Suzanne after her father Jacques (who had run into trouble with the legal and religious authorities for fornication and having a mistress) died in his early 30s. In 1695, Suzanne had to answer charges that she had attended a street theater disguised as a peasant woman so she could gaze upon M. Vincent Sarrasin, whom she fancied despite his continuing marriage. After a hearing, she was ordered by the Genevan Consistory to never interact with him again. She married Rousseau's father at the age of 31. Isaac's sister had married Suzanne's brother eight years earlier, after she had become pregnant and they had been chastised by the Consistory. The child died at birth. Later, the young Rousseau was told a romantic fairy-tale about the situation by the adults in his family—a tale where young love was denied by a disapproving patriarch but that prevailed by sibling loyalty that, in the story, resulted in love conquering all and two marriages uniting the families on the same day. Rousseau never learnt the truth.

Rousseau was born in Geneva, which was at the time a city-state and a Protestant associate of the Swiss Confederacy. Since 1536, Geneva had been a Huguenot republic and the seat of Calvinism. Five generations before Rousseau, his ancestor Didier, a bookseller who may have published Protestant tracts, had escaped persecution from French Catholics by fleeing to Geneva in 1549, where he became a wine merchant.
