# Physiocracy **The model:** Physiocracy — literally "rule of nature" — was the first true *school* of economics, a group of French thinkers led by François Quesnay in the 1750s–60s who held that all real wealth ultimately springs from **land and agriculture**. Manufacturing and commerce, in their view, were "sterile": useful, but merely transforming or moving value that agriculture alone created. Though this central claim was wrong, the Physiocrats invented much of the *method* and several of the core intuitions of modern economics, and coined its most enduring slogan. ## Core mechanisms Quesnay's *Tableau Économique* (1758) was a genuine breakthrough: the first attempt to model the entire economy as a **circular flow** — tracing how the "net product" of agriculture circulates among the productive class (farmers), the proprietary class (landowners), and the sterile class (artisans and merchants). It is the direct ancestor of input-output analysis and of national-income accounting. From the premise of a self-regulating "natural order," the Physiocrats drew a policy conclusion that would outlive their theory: **laissez-faire, laissez-passer** — government should stop obstructing the natural economic order, dismantle the tangle of Mercantilism restrictions and internal tariffs strangling French agriculture, and tax only the net product of land (the *impôt unique*, a single tax on land rent that prefigures [[Georgism]]). ## Right-wing relevance Physiocracy is the *historical origin* of the free-market tradition the vault spends so much time mapping. It coined "laissez-faire," and Adam Smith — who met Quesnay and Turgot in Paris and admired them — carried the idea of a self-regulating natural order into [[Classical Economics]], from which it descends to the [[Austrian School]], [[Chicago School]], and modern libertarianism. Knowing this genealogy is useful in two ways: it locates the deep root of "the market as natural order that government should not obstruct," and it supplies a cautionary note — the founding free-market school was built on a theory (only land is productive) that was demonstrably false, a reminder that intellectual pedigree is not proof. Turgot's brief, failed attempt to implement Physiocratic reforms as a French minister (before the Revolution) is also an early case study in the politics of liberalizing a rent-extracting order. ## Critiques and successors The core error — that only agriculture is productive — was refuted by [[Classical Economics]] (Smith, then Ricardo), which recognized labor and capital across all sectors as sources of value. But the Physiocrats' method (the economy as a modelable system), their laissez-faire policy stance, and their land-tax idea all survived: the first into all of modern macroeconomics, the second into free-market thought, the third into [[Georgism]]. ## See also - [[Classical Economics]] — the successor that corrected and absorbed it - Invisible Hand — the self-regulating order it prefigured - [[Georgism]] — the land-tax idea it originated - Mercantilism — the system it revolted against - [[Austrian School]] — a distant heir of its natural-order intuition
