What you’ll learn

  1. 1776 and the Making of a ClassicUnderstand who Smith was, the mercantilist world he wrote against, and the central question of the Wealth of Nations.Published in March 1776, the Wealth of Nations was written by moral philosopher Adam Smith, not an economist — the field did not yet exist. Smith wrote against mercantilism, which equated national wealth with hoarded gold and treated trade as zero-sum. He redefined wealth as a nation's annual production of goods and services.
  2. The Division of Labour and the Pin FactoryExplain the division of labour and the role of self-interest and exchange in coordinating a specialized society.Smith opens with the pin factory to show how splitting work into specialized operations multiplies output enormously. This division of labour, limited by the size of the market, is his answer to the source of wealth. Specialization makes people interdependent, and self-interested exchange — not benevolence — coordinates the whole society.
  3. The Invisible Hand and Free MarketsInterpret the invisible hand in its real context and understand Smith's genuine, nuanced case for free markets and trade.Smith's 'invisible hand' appears once, describing how self-interested investment can unintentionally benefit society. He was no cheerleader for unrestrained capitalism: he distrusted colluding businessmen, backed public goods, and demolished mercantilist tariffs. Free trade, he argued, enriches both parties, the same logic as the division of labour applied between nations.
  4. Legacy of the Wealth of NationsTrace the book's influence on economics and policy, and correct the caricatures that flatten Smith's thought.The Wealth of Nations founded economics as a discipline, shaping Ricardo, Mill, and even Marx, and inspiring real free-trade policy like the repeal of the Corn Laws. Later readers reduced Smith to a laissez-faire slogan or dismissed him as an apologist for greed. Read whole, he is a moral philosopher who saw markets as one institution needing justice and public works to serve people humanely.

Questions this course answers

What was Adam Smith's profession when he wrote the Wealth of Nations?

Smith was a moral philosopher, already known for 'The Theory of Moral Sentiments'; the profession of economist did not yet exist.

Which economic doctrine was Smith arguing against?

Smith attacked mercantilism, which saw wealth as bullion and trade as a zero-sum contest, arguing instead that wealth is a nation's annual production.

What point does Smith's pin factory example illustrate?

By splitting pin-making into ~18 operations, ten workers make ~48,000 pins a day versus one apiece — the power of specialization.

According to Smith, why does the butcher provide our dinner?

Smith's famous line: we get our dinner not from the butcher's benevolence 'but from their regard to their own interest.'

How often does the phrase 'invisible hand' actually appear in the Wealth of Nations?

The metaphor appears just once, discussing why merchants favor domestic investment, where private gain unintentionally promotes public good.

Which view did Smith actually hold about businessmen?

Smith warned that people of the same trade meeting together tend to conspire against the public or contrive to raise prices.
