Adam Smith's Legacy
Blog: Blog - Adam Smith Institute
On this day in 1790, the great economist, moral philosopher and social psychologist AdamSmith died. The story is that he was entertaining friends at his home, Panmure House offEdinburgh's Canongate, when he felt unwell, rose and said: "Friends, we will have tocontinue this conversation in another place." He died soon after.It's a nice story, though greatly exaggerated for effect. Adam Smith's religious beliefs are amatter of debate, and it unlikely he believed in an afterlife anyway. Indeed, though he diedseventy years before Darwin's Origin of Species, he was grasping towards an evolutionaryexplanation of why human life, in economics, morality and other areas, seems to serve us ingenerally beneficial ways, without the need for any conscious direction from governmentsor anyone else. As if directed by an Invisible Hand, he wrote, though he knew there was noconscious entity moving that hand. Or Providence, he suggested. How it generated theharmony that F A Hayek would later call spontaneous order was a mystery to Smith, and tohis friend David Hume and other scholars of the age.Smith ordered that, on his death, all his papers should be burned, apart from one essay onThe History of Astronomy. It was not such an uncommon request at the time: people did notwant to be judged on the basis of their random notes and half-though-out jottings. But wewere lucky he spared The History of Astronomy, which is a remarkable essay in thephilosophy of science, advancing a trial-and-error thesis that would not be lost on thetwentieth-century author of The Logic of Scientific Discovery, Sir Karl Popper.The fact that Smith wrote on scientific method demonstrates how wide his interestsand his expertise were. As well as the economics for which he is most remembered today, he alsowrote and lectured on the use of language, on the arts, on justice, on politics and on moralphilosophy. In fact it was his first book on ethics, The Theory of Moral Sentiments, that in1759 made him internationally famous — and guaranteed him a generous income for lifethat would give him the freedom to think about economics and write his 1776 masterpieceAn Inquiry into the Nature and Causes of the Wealth of Nations, which he referred to as hisInquiry, but to us is known as simply The Wealth of Nations.In this, Smith offers an explanation of why, in economics, the spontaneous order ideaworks. For centuries, people imagined that the only gainers in any economic transactionwere those who ended up with the money. But Smith noted that their customers benefitedtoo, by getting goods or services that they valued more than the cash. Indeed, the tradewould not happen unless both sides thought they were getting value from it. To maximisethe creation and distribution of value, he concluded, we need to be facilitating freeexchange — not thwarting it with protectionist measures against foreign imports ordomestic regulations on what and how people are allowed to trade.This simple 'system of natural liberty', explained Smith, was what allowed the spontaneoussociety to flourish and raised nations from poverty to prosperity. It enabled individuals tostrive to 'better their condition', and that of their families. By contrast, regulations and lawswere too often laid down by politicians and their business cronies: to promote their owninterests, most generally in opposition to the interests of the working poor.Smith would have regarded a government that controls nearly half the economy, spendingnearly half the nation's GDP — a concept that he introduced to the world on the very firstpage of The Wealth of Nations — as the greatest tyranny. Taxes, he thought, were anotherway in which established interests skew things in their favour and block potentialcompetition. Taxes, he argued, should be as low as possible, should encourage rather thanrestrict free trade and innovation, and should be simple, understandable and convenient topay. One can imagine what he might have thought of a tax code like the UK's, which islonger than The Wealth of Nations itself, and a regulatory rule book that is even longer.When economic freedom, tempered by Smith's moral virtues of prudence, justice,beneficence and self-control, has been allowed to flourish, it has led to the greatestincrease, and spread, of human prosperity. The free trade era of the nineteenth centuryenriched much of the world and brought humanity cheap food and manufactures. Theglobalisation of the twentieth and twenty-first brought nearly all nations into the worldtrading system and thereby pulled a billion people out of dollar-a-day poverty.Adam Smith's intellectual and practical legacy is plain enough. The issue is whether theworld's governments will ever stop frittering it away.
