Physiocrats

The Physiocrats were an economic school that emerged in the mid-18th century in France and hold a significant place in the history of economics. The founder of this school, who was also a physician, is François Quesnay. The term “Physiocracy” is of Greek origin and means “rule of nature.” According to the Physiocrats, the economy should function in accordance with the laws of nature.

1. The View That Agriculture Is the Only Productive Sector: The Physiocrats argued that the sole source of national wealth was agriculture. They regarded other sectors such as industry and trade as unproductive, merely transforming goods rather than creating new value. Consequently, they labeled activities outside agriculture as “sterile” sectors.
2. The Principle of Natural Order and Free Market: The Physiocrats maintained that economic life must operate according to the laws of nature. They opposed state intervention in the economy and adopted the principle of “Laissez faire, laissez passer” (let do, let pass). They are among the earliest advocates of free market economics.
3. The Economic Circulation Model – The Economic Table: François Quesnay developed the “Tableau Économique” (Economic Table), recognized as the first systematic economic model in history. This diagram illustrates the flows of income and expenditure among the productive class, landowners, and the sterile class, thereby laying the foundations for understanding the circular nature of economic activity.

1. François Quesnay: He is regarded as the founder and most important representative of the Physiocratic movement. The foundation of his economic thought lies in the productivity of land and the agricultural sector. Quesnay argued that value could be generated only through agriculture and built this view into the framework of what became known as the “Physiocratic School”. His most famous work, the “Economic Table” (Tableau Économique), is the first systematic model illustrating how the economy functions. This table explains the economic relationships among various actors in the economy—farmers, industrialists, and merchants. Quesnay’s central belief was that state intervention in the economy should be minimized and that free market economics should be supported.
2. Anne Robert Jacques Turgot: Turgot is known as a French economist and reformer. He was closely aligned with the Physiocratic movement but, unlike Quesnay, strongly advocated for economic freedoms and was a staunch defender of free market economics. Turgot emphasized the importance of free trade in agriculture, believing that agriculture formed the foundation of the economy. Among his most important reforms were the reorganization of agricultural taxes in France and initiatives aimed at promoting agricultural development. Turgot also highlighted the significance of privatization and free trade, arguing that state intervention hindered economic growth. He worked to abolish customs duties in France and paved the way for free trade.
3. Pierre Samuel du Pont de Nemours: Pierre Samuel du Pont de Nemours was a French economist and industrialist. As one of the leading figures of the Physiocratic school, he was a vigorous advocate of economic freedoms and free trade. Like Quesnay and Turgot, du Pont argued that state intervention had a distorting effect on the economy. At the same time, he emphasized the importance of industrial production for economic development. While defending the economic freedom of agriculture, du Pont de Nemours also embraced the benefits of the Industrial Revolution, adopting a broader economic perspective. He played a significant role in the modernization of the French economy.
