Jean-Jacques Rousseau remains an important figure in the history of philosophy, both because of his contributions to political philosophy and moral psychology and because of his influence on later thinkers. Rousseau’s own view of philosophy and philosophers was firmly negative, seeing philosophers as the post-hoc rationalizers of self-interest, as apologists for various forms of tyranny, and as playing a role in the alienation of the modern individual from humanity’s natural impulse to compassion. The concern that dominates Rousseau’s work is to find a way of preserving human freedom in a world where human beings are increasingly dependent on one another for the satisfaction of their needs. This concern has two dimensions: material and psychological, of which the latter has greater importance. In the modern world, human beings come to derive their very sense of self from the opinion of others, a fact which Rousseau sees as corrosive of freedom and destructive of individual authenticity. In his mature work, he principally explores two routes to achieving and protecting freedom: the first is a political one aimed at constructing political institutions that allow for the co-existence of free and equal citizens in a community where they themselves are sovereign; the second is a project for child development and education that fosters autonomy and avoids the development of the most destructive forms of self-interest. However, though Rousseau believes the co-existence of human beings in relations of equality and freedom is possible, he is consistently and overwhelmingly pessimistic that humanity will escape from a dystopia of alienation, oppression, and unfreedom. In addition to his contributions to philosophy, Rousseau was active as a composer and a music theorist, as the pioneer of modern autobiography, as a novelist, and as a botanist. Rousseau’s appreciation of the wonders of nature and his stress on the importance of feeling and emotion made him an important influence on and anticipator of the romantic movement. To a very large extent, the interests and concerns that mark his philosophical work also inform these other activities, and Rousseau’s contributions in ostensibly non-philosophical fields often serve to illuminate his philosophical commitments and arguments.

1. Life

Jean-Jacques Rousseau was born in the independent Calvinist city-state of Geneva in 1712, the son of Isaac Rousseau, a watchmaker, and Suzanne Bernard. Rousseau’s mother died nine days after his birth, with the consequence that Rousseau was raised and educated by his father until the age of ten. Isaac Rousseau was one of the small minority of Geneva’s residents who enjoyed the rank of citizen of Geneva, a status which Jean-Jacques was to inherit. According to Rousseau’s own subsequent accounts, the haphazard education that he received from his father included both the inculcation of republican patriotism and the reading of classical authors such as Plutarch who dealt with the Roman republic. On his father’s exile from the city to avoid arrest, Jean-Jacques was put in the care of a pastor at nearby Bossey and subsequently apprenticed to an engraver. Rousseau left the city at the age of sixteen and came under the influence of a Roman Catholic convert noblewoman, Francoise-Louise de la Tour, Baronne de Warens. Mme de Warens arranged for Rousseau to travel to Turin, where he converted to Roman Catholicism in April 1728. Rousseau spent some time working as a domestic servant in a noble household in Turin, and during this time a shameful episode occurred in which he falsely accused a fellow servant of the theft of a ribbon. This act marked him deeply and he returns to it in his autobiographical works.

Rousseau then spent a brief period training to become a Catholic priest before embarking on another brief career as an itinerant musician, music copyist and teacher. In 1731 he returned to Mme de Warens at Chambéry and later briefly became her lover and then her household manager. Rousseau remained with Mme de Warens through the rest of the 1730s, moving to Lyon in 1740 to take up a position as a tutor. This appointment brought him within the orbit of both Condillac and d’Alembert and was his first contact with major figures of the French Enlightenment. In 1742 he travelled to Paris, having devised a plan for a new numerically-based system of musical notation which he presented to the Academy of Sciences. The system was rejected by the Academy, but in this period Rousseau met Denis Diderot. A brief spell as secretary to the French Ambassador in Venice followed before Rousseau moved to Paris on a more permanent basis from 1744, where he continued to work mainly on music and began to write contributions to the Encyclopédie of Diderot and d’Alembert.

In 1745 Rousseau met Thérèse Levasseur, a barely literate laundry-maid who became his lover and, later, his wife. According to Rousseau’s own account, Thérèse bore him five children, all of whom were deposited at the foundling hospital shortly after birth, an almost certain sentence of death in eighteenth-century France. Rousseau’s abandonment of his children was later to be used against him by Voltaire.

In 1749, while walking to Vincennes to visit the briefly-imprisoned Diderot, Rousseau came across a newspaper announcement of an essay competition organized by the Academy of Dijon. The Academy sought submissions on the theme of whether the development of the arts and sciences had improved or corrupted public morals. Rousseau later claimed that he then and there experienced an epiphany which included the thought, central to his world view, that humankind is good by nature but is corrupted by society. Rousseau entered his Discourse on the Sciences and Arts (conventionally known as the First Discourse) for the competition and won first prize with his contrarian thesis that social development, including of the arts and sciences, is corrosive of both civic virtue and individual moral character. The Discourse was published in 1750 and is mainly important because Rousseau used it to introduce themes that he then developed further in his later work, especially the natural virtue of the ordinary person and the moral corruption fostered by the urge to distinction and excellence. The First Discourse made Rousseau famous and provoked a series of responses to which he in turn replied.

Music remained Rousseau’s primary interest in this period, and the years 1752 and 1753 saw his most important contributions to the field. The first of these was his opera Le Devin du Village (The Village Soothsayer), which was an immediate success (and stayed in the repertoire for a century). The second was his participation in the “querelle des bouffons”, a controversy that followed the performance in Paris of Pergolesi’s La Serva Padrona by a visiting Italian company and which pitted the partisans of Italian music against those of the French style. Rousseau, who had already developed a taste for Italian music during his stay in Venice, joined the dispute through his Letter on French Music and the controversy also informed his (unpublished) Essay on the Origin of Languages. Rousseau’s emphasis on the importance of melody and the communication of emotion as central to the function of music was in opposition to the views of Rameau, who stressed harmony and the relationship between music, mathematics, and physics. Rousseau went so far as to declare the French language inherently unmusical, a view apparently contradicted by his own practice in Le Devin.

Rousseau’s conversion to Catholicism had rendered him ineligible for his hereditary status as Citizen of Geneva. In 1754 he regained this citizenship by reconverting to Calvinism. In the following year he published his Discourse on the Origins of Inequality, again in response to an essay competition from the Academy of Dijon. Though he did not win the Academy’s prize a second time, the Second Discourse is a far more accomplished work, and in it Rousseau begins to develop his theories of human social development and moral psychology. With the Second Discourse, the distance between Rousseau and the Encyclopédiste mainstream of the French Enlightenment thought became clear. This rift was cemented with his 1758 publication of the Letter to d’Alembert on the Theater, in which he denounced the idea that his native city would benefit from the construction of a theater. In Rousseau’s view theater, far from improving the population, tends to weaken their attachment to the life of the polis.

The years following the publication of the Second Discourse in 1755 were the most productive and important of Rousseau’s career. He withdrew from Paris and, under the patronage of, first Mme d’Epinay and then the Duke and Duchess of Luxembourg, worked on a novel, Julie, ou La Nouvelle Héloïse, and then on Emile and The Social Contract. Julie appeared in 1761 and was an immediate success. The novel is centred on a love triangle between Julie, her tutor Saint Preux and her husband Wolmar. The work is cast in epistolary form, and is an important supplementary source for the interpretation of Rousseau’s social philosophy, containing, as it does, such elements as a vision of rural community and the presence of a manipulative genius who achieves the appearance of natural harmony through cunning artifice and who thus anticipates both the tutor in Emile and the legislator of The Social Contract. Both works appeared in 1762, marking the high point of Rousseau’s intellectual achievement.

Unfortunately for Rousseau, the publication of these works led to personal catastrophe. Emile was condemned in Paris and both Emile and The Social Contract were condemned in Geneva on grounds of religious heterodoxy. Partly in response to this, Rousseau finally renounced his Genevan citizenship in May 1763. Rousseau was forced to flee to escape arrest, seeking refuge first in Switzerland and later, in January 1766, at the invitation of David Hume, travelling to England.

Rousseau’s stay in England was marked by increasing mental instability and he became wrongly convinced that Hume was at the center of a plot against him. He spent fourteen months in Staffordshire where he worked on his autobiographical work, the Confessions, which also contains evidence of his paranoia in its treatment of figures like Diderot and the German author Friedrich Melchior, Baron von Grimm. He returned to France in 1767 and then spent much of the rest of his life working on autobiographical texts, completing the Confessions but also composing the Dialogues: Rousseau Judge of Jean-Jacques and The Reveries of the Solitary Walker. He also completed his Considerations on the Government of Poland in this period. In later life he further developed his interest in botany (where his work proved influential in England via his letters on the subject to the Duchess of Portland) and in music, as he met and corresponded with the operatic composer Christoph Gluck. Rousseau died in 1778. In 1794 the French revolutionaries transferred his remains to the Panthéon in Paris.

2. Conjectural history and moral psychology

Rousseau repeatedly claims that a single idea is at the centre of his world view, namely, that human beings are good by nature but are rendered corrupt by society. Unfortunately, despite the alleged centrality of this claim, it is difficult to give it a clear and plausible interpretation. One obvious problem is present from the start: since society, the alleged agent of corruption, is composed entirely of naturally good human beings, how can evil ever get a foothold? It is also difficult to see what “natural goodness” might be. In various places Rousseau clearly states that morality is not a natural feature of human life, so in whatever sense it is that human beings are good by nature, it is not the moral sense that the casual reader would ordinarily assume. In order, therefore, to address this puzzling central claim, it is best to look first at the details of Rousseau’s moral psychology, especially as developed in the Discourse on the Origins of Inequality and in Emile.

Rousseau attributes to all creatures an instinctual drive towards self-preservation. Human beings therefore have such a drive, which he terms amour de soi (self love). Amour de soi directs us first to attend to our most basic biological needs for things like food, shelter and warmth. Since, for Rousseau, humans, like other creatures, are part of the design of a benevolent creator, they are individually well-equipped with the means to satisfy their natural needs. Alongside this basic drive for self-preservation, Rousseau posits another passion which he terms pitié (compassion). Pitié directs us to attend to and relieve the suffering of others (including animals) where we can do so without danger to our own self-preservation. In some of his writings, such as the Second Discourse, pitié is an original drive that sits alongside amour de soi, whereas in others, such as Emile and the Essay on the Origin of Languages, it is a development of amour de soi considered as the origin of all passions.

In the Discourse on the Origins of Inequality Rousseau imagines a multi-stage evolution of humanity from the most primitive condition to something like a modern complex society. Rousseau denies that this is a reconstruction of history as it actually was, and Frederick Neuhouser (2014) has argued that the evolutionary story is merely a philosophical device designed to separate the natural and the artificial elements of our psychology. At each step of this imagined evolution human beings change their material and psychological relations to one another and, correspondingly, their conception of themselves, or what Rousseau calls the “sentiment of their existence.” According to this narrative, humans live basically solitary lives in the original state of the human race, since they do not need one another to provide for their material needs. The human race barely subsists in this condition, chance meetings between proto-humans are the occasions for copulation and reproduction, child-care is minimal and brief in duration. If humans are naturally good at this stage of human evolution, their goodness is merely a negative and amounts to the absence of evil. In this story, human beings are distinguished from the other creatures with which they share the primeval world only by two characteristics: freedom, and perfectibility. Freedom, in this context, is simply the ability not to be governed solely by appetite; perfectibility is the capacity to learn and thereby to find new and better means to satisfy needs. Together, these characteristics give humans the potential to achieve self-consciousness, rationality, and morality. Nevertheless, it will turn out that such characteristics are more likely to condemn them to a social world of deception, dissimulation, dependence, oppression, and domination.

As human populations grow, simple but unstable forms of co-operation evolve around activities like hunting. According to Rousseau, the central transitional moment in human history occurs at a stage of society marked by small settled communities. At this point a change, or rather a split, takes place in the natural drive humans have to care for themselves: competition among humans to attract sexual partners leads them to consider their own attractiveness to others and how that attractiveness compares to that of potential rivals. In Emile, where Rousseau is concerned with the psychological development of an individual in a modern society, he also associates the genesis of amour propre with sexual competition and the moment, puberty, when the male adolescent starts to think of himself as a sexual being with rivals for the favours of girls and women.

Rousseau’s term for this new type of self-interested drive, concerned with comparative success or failure as a social being, is amour propre (love of self, often rendered as pride or vanity in English translations). Amour propre makes a central interest of each human being the need to be recognized by others as having value and to be treated with respect. The presentation of amour propre in the Second Discourse—and especially in his note XV to that work—often suggests that Rousseau sees it as a wholly negative passion and the source of all evil. Interpretations of amour propre centered on the Second Discourse (which, historically, are the most common ones (for example Charvet 1974)), often focus on the fact that the need for recognition always has a comparative aspect, so that individuals are not content merely that others acknowledge their value, but also seek to be esteemed as superior to them. This aspect of our nature then creates conflict as people try to exact this recognition from others or react with anger and resentment when it is denied to them. More recent readings of both the Second Discourse, and especially of Emile, have indicated that a more nuanced view is possible (Den 1988, Neuhouser 2008). According to these interpretations, amour propre is both the cause of humanity’s fall as well as the promise of its redemption because of the way in which it develops humans’ rational capacities and their sense of themselves as social creatures among others. Although Rousseau held that the overwhelming tendency, socially and historically, is for amour propre to take on toxic and self-defeating (‘inflamed’) forms, he also held that there are, at least in principle, ways of organizing social life and individual education that allow it to take on a benign character. This project of containing and harnessing amour propre finds expression in both The Social Contract and Emile. In some works, such as the Second Discourse, Rousseau presents amour propre as a passion that is quite distinct from amour de soi. In others, including Emile, he presents it as a form that amour de soi takes in a social environment. The latter is consistent with his view in Emile that all the passions are outgrowths or developments of amour de soi.
