Why is Adam Smith often considered an important influence on classical liberalism and capitalism?

Adam Smith is considered a foundational figure in classical liberalism and capitalism because he provided the first comprehensive system of political economy in his seminal work, An Inquiry into the Nature and Causes of the Wealth of Nations (1776).12

His influence stems from several key contributions:

• System of Perfect Liberty: Smith advocated for a transition from government-constrained enterprise to a system of market-determined wages and free exchange, which later became known as laissez-faire capitalism.12
• The Invisible Hand: He introduced the metaphor of the invisible hand to explain how individuals, while pursuing their own self-interest, are often led to promote the public good without intending to do so.34
• Philosophical Foundation: Smith’s economic theories were rooted in his broader work on human nature and moral philosophy, particularly his earlier book, The Theory of Moral Sentiments (1759). He viewed society as evolving through historical stages, with economic institutions—such as private property—emerging to meet the needs of commercial interdependence.142

By synthesizing these ideas, Smith established a framework that prioritized individual agency and market mechanisms as drivers of social and economic progress.32
