18th Century Moral Philosopher & Economist
Adam Smith
Scottish philosopher and economist whose ideas about free markets, division of labor, and the role of self-interest laid the foundations of modern economics.
Who Was Adam Smith?
Adam Smith (1723–1790) was a Scottish philosopher, economist, and key figure of the Scottish Enlightenment. He studied moral philosophy at the University of Glasgow and later became a professor there, teaching subjects such as ethics, jurisprudence, and political economy.
Smith is best known for his work “An Inquiry into the Nature and Causes of the Wealth of Nations” (1776) commonly known as "The Wealth of Nations", widely considered the founding text of modern economics. In this work he examined how markets function, how labor specialization increases productivity, and how economic systems can operate without central direction.
However, Smith was not only an economist. His earlier work, “The Theory of Moral Sentiments” (1759), explored human behavior, sympathy, and moral judgment. Together, these works show that Smith believed economic systems should exist within a framework of moral responsibility and social institutions.
Smith's ideas influenced the development of classical liberalism, free-market economics, and modern political economy.
“It is not from the benevolence of the butcher, the brewer, or the baker that we expect our dinner, but from their regard to their own interest.”
Key Ideas
Division of Labor
Smith argued that productivity increases when work is divided into specialized tasks. In The Wealth of Nations, he famously illustrated this through a pin factory, showing how workers performing specialized roles could dramatically increase total production.
The Invisible Hand
Smith introduced the concept often called the “invisible hand,” describing how individuals pursuing their own interests in a competitive market can unintentionally contribute to the overall prosperity of society.
Free Markets
Smith believed markets function best when individuals are free to exchange goods and services with minimal government interference. Competition encourages efficiency, innovation, and lower prices.
Limited Government
Although often associated with laissez-faire economics, Smith believed government still had important roles, including:
-
protecting national security
-
enforcing justice and property rights
-
building public infrastructure that markets alone might not provide
Major Works
The Theory of Moral Sentiments
1759
a foundational work of moral philosophy that explores how humans form moral judgments through sympathy and the "impartial spectator," arguing that our sense of right and wrong comes from our ability to imagine others' feelings and judge ourselves as an objective observer would.
The Wealth of Nations
1776
Smith’s most famous work and a cornerstone of economic theory. It explores how markets operate, how wealth is created, and how economic systems develop.
Lectures on Jurisprudence
1763
a collection of Adam Smith's lecture notes from the University of Glasgow (1762–1763), outlining his theory of government, which centers on preserving justice by protecting individual rights to person, property, reputation, and social relations.
Political Influence
Adam Smith’s ideas played a foundational role in shaping modern economic and political thought. His work laid the intellectual groundwork for classical liberalism, a tradition that emphasizes individual liberty, free markets, and limited government intervention in economic life. Smith argued that when individuals are free to pursue their own interests within a system of secure property rights and open competition, markets can coordinate economic activity more efficiently than centralized planning. These ideas heavily influenced the development of modern capitalism and the study of political economy, inspiring later economists and philosophers such as David Ricardo, Friedrich Hayek, and Milton Friedman. Today, Smith’s work continues to influence debates about economic freedom, regulation, globalization, and the proper role of government in the marketplace.
