Physiocracy

Physiocracy is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Physiocracy rather than just read about it. In short: Physiocracy (French: physiocratie; from the Greek for "government of nature") is an economic theory developed by a group of 18th-century Age of Enlightenment French economists. They believed that the wealth of nations derived solely from the value of "land agriculture" or "land development" and that agricultural products should be highly priced.

Key takeaways

  • Physiocracy belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Physiocracy to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Physiocracy from memory before moving on to harder problems.

Reference excerpt

Physiocracy (French: physiocratie; from the Greek for "government of nature") is an economic theory developed by a group of 18th-century Age of Enlightenment French economists. They believed that the wealth of nations derived solely from the value of "land agriculture" or "land development" and that agricultural products should be highly priced. Their theories originated in France and were most popular during the second half of the 18th century. Physiocracy became one of the first well-developed theories of economics. François Quesnay (1694–1774), the Marquis de Mirabeau (1715–1789) and Anne-Robert-Jacques Turgot (1727–1781) dominated the movement, which immediately preceded the first modern school, classical economics, which began with the publication of Adam Smith's The Wealth of Nations in 1776. The physiocrats made a significant contribution in their emphasis on productive work as the source of national wealth. This contrasted with earlier schools, in particular mercantilism, which often focused on the ruler's wealth, accumulation of gold, or the balance of trade. Whereas the mercantilist school of economics held that value in the products of society was created at the point of sale, by the seller exchanging his products for more money than the products had "previously" been worth, the physiocratic school of economics was the first to see labor as the sole source of value. For the physiocrats, however, only agricultural labor created this value in the products of society. All "industrial" and non-agricultural labors were "unproductive appendages" to agricultural labor. Quesnay was likely influenced by his medical training, particularly by the work of William Harvey who explained how blood flow and the circulatory system is vital to the human body; Quesnay held that the circulation of wealth was vital to the economy. Societies at the time were also overwhelmingly agrarian. This may be why they viewed agriculture as the primary source of a nation's wealth. This is an idea that Quesnay purported to demonstrate with data, comparing a workshop to a farm. He analyzed "how money flowed between the three classes of farmers, proprietors, and artisans, in the same mechanical way that blood flows between different organs" and claimed only the farm produced a surplus that added to the nation's wealth. Physiocrats viewed the production of goods and services as equivalent to the consumption of the agricultural surplus, since human or animal muscle provided the main source of power and all energy derived from the surplus from agricultural production. Profit in capitalist production was really only the "rent" obtained by the owner of the land on which the agricultural production took place. "The physiocrats damned cities for their artificiality and praised what they considered to be more natural styles of living. They celebrated farmers." They called themselves les Économistes, but are generally referred to as "physiocrats" to distinguish their beliefs from the many schools of economic thought that followed.

History

Ancient precursors Physiocracy is an agrarianist philosophy that developed in the context of the predominantly rural, pre-industrial European society of the time. In the late Roman Republic, the dominant senatorial class was not allowed to engage in banking or commerce but relied on their latifundia, large plantations, for income. They circumvented this rule through freedmen proxies who sold surplus agricultural goods. Other inspiration came from China's economic system, then the largest in the world. Chinese society broadly distinguished four occupations, with scholar-bureaucrats (who were also agrarian landlords) at the top and merchants at the bottom (because they did not produce but only distributed goods made by others). Leading physiocrats like François Quesnay were avid Confucians who advocated China's agrarian policies. Some scholars have advocated connections with the school of agriculturalism, which promoted utopian communalism. One of the integral parts of physiocracy, laissez-faire, was adopted from Quesnay's writings on China, being a translation of the Chinese Taoism term wu wei. The concept natural order of physiocracy originated from "Way of Nature" of Chinese Taoism.

Worked examples

Example 1 — a first encounter with Physiocracy

Start with the simplest possible case. Write down what Physiocracy claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Physiocracy before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Physiocracy ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Physiocracy

In research
Physiocracy appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Physiocracy in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Physiocracy is common in secondary-school and first-year university syllabi. It links to neighbouring topics Agrarianism, Classical liberalism, Georgism, so understanding it makes those chapters shorter.
In everyday life
Look for Physiocracy outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
