19th century

The nineteenth century appears in this account both as an age of Rousseau’s continuing reach and as one in which his work was often cited more readily than understood. His influence extended across literature, education, and political philosophy, while the survival of the language of the Social Contract showed how an inherited political vocabulary could outlast belief in its literal historical story.

A contested inheritance

A century and a half after the publication of the Social Contract, Jean-Jacques Rousseau remained a controversial watchword and a party cry. Admirers and opponents alike often judged his political doctrines wholesale, shaped by political allegiance rather than careful discrimination. He was revered or hated as the writer said, above all others, to have inspired the French Revolution, even while his standing as one of France’s greatest writers was widely acknowledged.

That contested reputation coexisted with an influence reaching well beyond immediate political argument. Rousseau helped give shape to the Romantic movement in art, letters, and life, affected German Romantics and Goethe, and established a new fashion for introspection that permeated nineteenth-century literature. His work also contributed to modern educational theory. In political thought, he represented a passage from a traditional theory rooted in the Middle Ages toward a modern philosophy of the State; his influence on Immanuel Kant’s moral philosophy and Georg Wilhelm Friedrich Hegel’s philosophy of Right expressed different aspects of that contribution.

From slogan to study

Political actors in the French Revolution, from Robespierre onward, had studied Rousseau’s writings attentively, though they often appeared to misunderstand them. In the nineteenth century, people continued to appeal to him, but generally without knowing his work well or penetrating its meaning. As M. Dreyfus-Brisac observed, the Social Contract was the book most talked about and least read. Its name could serve as an authority for views about circumstances Rousseau himself could never have contemplated.

A revival of interest in political philosophy brought a different approach: Rousseau was increasingly treated as a thinker to be examined, rather than simply an ally or adversary. The aim was to sift what was true from what was mistaken and to seek in the Social Contract its principles of political right. That change in readership also reframed the book’s significance. It could be read as a document of the French Revolution, but its lasting claim rested on its value as a work of political philosophy. Understanding that value required historical insight—not to dismiss questions that seemed outdated, but to see whether Rousseau’s answers held when those questions were reformulated for a later age.

Inherited concepts and political change

Rousseau’s importance, this account argues, cannot be judged by treating him as an isolated innovator. He was at once an early modern political theorist and the last in a long line of Renaissance theorists, themselves inheritors and transformers of medieval ideas. Critics who first separated the Social Contract from earlier works, then treated resemblances as proof that Rousseau had borrowed everything, mistook originality for isolation. His achievement lay instead in the new use of old ideas and in the transition he made within the general conception of politics.

The Social Contract itself belonged to a tradition that stretched back to the Greek sophists, recurred in medieval writing, and became commonplace among Renaissance theorists. By the eighteenth century, it was already approaching decline before a broader conception of politics. The contract form was easy to reach whenever reflection on government led to the thought that political authority rested, in some sense, on the consent of its members. Writers often gave that principle a historical setting, especially when they sought factual support for their theories or regarded society as unnatural. Rousseau used the familiar form of the contract, but did not make his case depend on the claim that an actual compact had occurred in remote history.

For Rousseau, the contract named the fundamental principle of political association: the basis of the unity through which people could attain political liberty by leaving lawlessness and license behind. It described something operative in every legitimate society, though absent under despotism. The account therefore distinguishes the inherited, quasi-historical presentation from the political idea it carries. The historical story could lose credibility while the phrase endured, because political thought still needed language for explaining the basis of union among members of a state.

The endurance of political language

The persistence of contractarian language into the nineteenth century illustrates the wider historical movement attributed to Rousseau. Political theory does not leap cleanly from old concepts to new ones; it adjusts and renovates inherited terms. Rousseau’s struggle to free the Social Contract theory from what was lifeless and outworn in it was part of the work by which he developed ideas that exceeded the theory’s original scope. His importance lay neither in preserving the old account unchanged nor in simply discarding it, but in making its vocabulary serve a changed conception of political life.

This historical approach also guards against reducing the Social Contract to a relic. Read too literally, Rousseau’s political thought might seem to possess only historical interest. Read in context, it becomes possible to distinguish what served his contemporaries from what may remain useful beyond them. The nineteenth-century return to Rousseau thus involved more than renewed attention to a celebrated name: it reopened the question of how political ideas travel through time, retaining old forms while acquiring new meanings.
