The Wealth of Nations
The Wealth of Nations (1776) is Adam Smith’s founding treatise of classical political economy — the book that made the systematic case that a nation grows rich through the division of labour and free exchange, not through the hoarding of gold or the direction of the state.
The division of labour
The book opens with the source of wealth, and it is not resources or money but organization. Productivity, Smith argues, rises when work is broken into specialized tasks:
“The greatest improvements in the productive powers of labour, and the greater part of the skill, dexterity, and judgment, with which it is anywhere directed, or applied, seem to have been the effects of the division of labour.”
His famous illustration is the pin factory, where a single untrained worker might make a handful of pins a day but ten workers dividing the eighteen distinct operations make tens of thousands. The division of labour is in turn limited by the extent of the market — the wider the market, the finer the specialization it can support — which is already an argument for free trade.
Self-interest and the invisible hand
Smith’s second great idea is that the market turns private self-interest into public benefit without anyone aiming at the public benefit. The exchange that feeds a city runs not on goodwill but on reciprocal advantage:
“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.”
From this follows the book’s most quoted image. A merchant who directs his capital to its most profitable domestic use intends only his own gain, and yet is “led by an invisible hand to promote an end which was no part of his intention” — the efficient allocation of a nation’s capital. It is the founding statement of what the wiki treats as spontaneous order: a beneficial overall pattern that is the result of human action but not of human design.
Against mercantilism
Much of the book is a sustained assault on the mercantile system — the doctrine that a nation’s wealth is its stock of gold and silver, and that trade should therefore be managed to run a surplus. Smith answers that wealth is the flow of goods a people can consume, not the metal in the treasury, and that tariffs, bounties, and monopolies enrich the protected interest at the general expense. His case for free trade — later sharpened by Ricardo into comparative advantage — is the classical-liberal core the wiki inherits.
Place in This Wiki
The wiki reads Smith as the foundation the later free-market tradition rests on, and as a foundation that needed repair. He is the ancestor of the spontaneous-order argument that runs through Hayek, and the classical-liberal case against mercantilism is common ground for every school in the wiki’s comparison of economic schools. But Smith also let the labour and cost of production drift toward being the source of value rather than a determinant of price — an error the marginal revolution later overturned, and one that the Austrian reading in Rothbard’s history treats as a step back from the earlier subjective-value insights of the Scholastics. Smith is thus both the classical liberal the tradition claims and a figure the Austrians read critically.
