Rousseau, Diderot and the Spirit of Catherine the Great's Reforms

In the Social Contract, Rousseau predicted that Europe would experience a cycle of increasingly intense wars, culminating in invasion from the east: first, Russia would conquer Europe's exhausted and war-torn states; then, Russia would itself become overextended and Europe would ultimately be overrun by the Tartars. The future of the modern state would be a version of the fall of Rome. The present essay provides an explanation of why Rousseau held such apocalyptic views by placing them in the context of projects to reform Europe's political economy in the aftermath of the Seven Years' War. In 1767, when Catherine the Great was planning a major revision of the Russian legal code, she outlined her goals in a manifesto called the Grand Instruction, key sections of which were derived from Montesquieu's analysis of depopulation of the countryside caused by uncontrolled industrialisation. The Grand Instruction became the subject of a critical exchange between the Physiocrat Le Trosne and Diderot, who, drawing upon Rousseau, was by turns both sympathetic to and sceptical of Physiocracy. This discourse reveals a triangular debate about the possibility of stabilising the international order by imposing a balance between the agricultural and manufacturing sectors of Europe's rapidly growing economies.
