Francois Quesnay
Founder of Physiocracy, argued agriculture was the sole source of wealth.
Who was Francois Quesnay?
François Quesnay (1694–1774) was a French economist and physician, the founder of the Physiocratic school of economic thought. He believed that only agriculture produced true wealth, conceptualising economic activity as a circular flow.
“That the sovereign authority be singular and superior to all individuals of society and to all unjust enterprises of particular interests; for the contrary would put the nation into confusion by a division of opinions dominant among the great.”
— Francois Quesnay, *General Maxims of the Economic Government of an Agricultural Kingdom*, 1767
François Quesnay (1694–1774), physician to King Louis XV, became the intellectual leader of the Physiocrats, the first formal school of economic thought. Opposing mercantilist policies that prioritised manufacturing and trade, Quesnay argued that land and agriculture were the sole sources of a nation's wealth, producing a "net product" (produit net) or surplus above costs. This view arose from his observation of the French economy, where agricultural output dominated.
Quesnay’s most famous contribution was the *Tableau Économique*, first published in 1758, a diagrammatic representation of the economy's circular flow of income and goods. It divided society into three classes: the productive class (farmers), the proprietor class (landowners), and the sterile class (artisans, manufacturers, merchants). The *Tableau* illustrated how wealth, originating in agriculture, circulated through these classes, showing that only the productive class generated a surplus.
His economic philosophy advocated for *laissez-faire, laissez-passer* policies, meaning minimal government intervention in the economy, particularly in agriculture. He believed that natural economic laws would ensure prosperity if free trade and production were allowed. Quesnay's ideas, articulated in works like *Philosophie Rurale* (1766), influenced later economists such as Adam Smith, who visited Quesnay in 1764 and initially intended to dedicate *The Wealth of Nations* to him.
Key Contributions
- Founded the Physiocratic school of economic thought in the mid-18th century, asserting agriculture as the sole source of wealth.
- Developed the *Tableau Économique* (1758), a seminal work illustrating the circular flow of income and expenditure in an economy.
- Advocated for *laissez-faire* policies, arguing for minimal government intervention in economic affairs, particularly regarding agriculture and trade, influencing early classical economists.
Legacy
Quesnay's *Tableau Économique* provided an early conceptual model of economic interdependencies, prefiguring modern macroeconomic flow diagrams. His emphasis on agricultural surplus and natural economic laws helped shift economic discourse away from mercantilist doctrines and towards classical liberal thought, influencing Adam Smith directly.
