On The Wealth of Nations

The Wealth of Nations is the most cited and least read book in economics, and the gap between the two has produced a caricature that would have startled its author. Adam Smith is invoked as the patron saint of unfettered markets and naked self-interest, the man of the invisible hand. Read him and you find something more interesting and far more humane: a moral philosopher who understood markets as a powerful tool embedded in a moral and legal order, and who distrusted the merchants and manufacturers whose greed he is now supposed to have blessed.

The famous idea is real but narrower than its reputation. Smith observed that in a well-ordered market, individuals pursuing their own gain are led, as if by an invisible hand, to promote ends they did not intend, namely the general prosperity. The butcher, the brewer, and the baker serve us our dinner not from benevolence but from regard to their own interest, and the result is that we are fed. This is a genuine and powerful insight: that decentralized, self-interested activity can coordinate the efforts of millions of strangers into a productive whole, without any central planner directing it.

But Smith hedged it heavily, and the hedges are the part the caricature drops. He was scathing about businessmen conspiring against the public, observing that people of the same trade seldom meet without the conversation ending in some contrivance to raise prices. He supported public goods, education, and a legal framework that markets could not supply themselves. The invisible hand works, in Smith, only inside the rule of law and a moral culture, and he wrote a whole separate book, The Theory of Moral Sentiments, on the sympathy and fellow-feeling he considered the foundation of social life.

The Wealth of Nations is here not as an economics textbook but as a foundational text in the long argument about the relationship between markets, government, and a free society. The questions Smith raised, how much should government do, where do markets serve the public and where do they betray it, what holds a commercial society together, are permanent political questions, and nearly every later argument about them is in conversation with this book, including the socialist critiques that answered it and the libertarian readings that claim it.

To read Smith honestly is to reclaim him from both his admirers and his critics, and to find a subtler thinker than either camp wants. The full text is public domain and freely available. It is enormous and digressive, written in the leisurely style of its century, so treat it as a quarry. Read the early chapters on the division of labor and the invisible hand, and the passages on the self-interest of merchants, and you will understand both what Smith argued and how badly he has been simplified.
