Adam Smith
The Father of Modern Economics
In 1776, the same year that thirteen colonies declared their independence from Britain, a retired Scottish professor published a book that would prove even more revolutionary. Adam Smith’s An Inquiry into the Nature and Causes of the Wealth of Nations dismantled centuries of economic orthodoxy in a single stroke. Against the prevailing wisdom that a nation’s wealth lay in its gold reserves and trade surpluses, Smith argued something radical: wealth was labour. It was the productive capacity of ordinary people, freely exchanging goods and services in open markets, that made nations rich. The book transformed political economy from a branch of moral philosophy into a discipline of its own, and its central insights — the division of labour, the invisible hand, the case for free trade — remain the foundations of modern economics.
“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.”
1723–1790
Born in Kirkcaldy, a small fishing town on the Firth of Forth in Scotland, and baptised on 5 June 1723. His father, also Adam Smith, was a customs comptroller who died before his son was born. Smith never married and lived much of his life with his mother, Margaret Douglas, who survived until 1784. He died in Edinburgh on 17 July 1790, aged sixty-seven.

Smith worked on The Wealth of Nations for a full decade, from 1766 to 1776, after returning from France. He secluded himself in Kirkcaldy with his mother and worked with such intensity that friends worried for his health. David Hume wrote urging him to finish. The result was over nine hundred pages across five books.

The Wealth of Nations went through five editions during Smith’s lifetime (1776, 1778, 1784, 1786, 1789). Each edition was carefully revised by Smith, who added new material, corrected errors, and sharpened his arguments. The third edition of 1784 was the most substantially revised, adding an entirely new chapter on colonies.

English, Latin, Greek, French, and Italian. Smith studied classics at Glasgow and Oxford, corresponded in French with Continental philosophers, and read Italian political economy in the original. His command of classical languages shaped his moral philosophy; his French opened the door to the Physiocrats.

Defining Events
The Theory of Moral Sentiments
Smith’s first masterpiece, published when he was thirty-six, established him as one of Europe’s leading philosophers. The book argued that morality arises not from reason or divine command but from sympathy — the human capacity to imagine ourselves in another person’s situation. Smith introduced the concept of the impartial spectator, an internalised judge through which we evaluate our own conduct. Voltaire praised it. Hume celebrated it. It made Smith famous across the Continent and secured his invitation to tour France as tutor to the young Duke of Buccleuch — the journey that would lead him to the Physiocrats and, ultimately, to The Wealth of Nations.
The Grand Tour of France
Hired by the politician Charles Townshend to tutor his stepson, the young Duke of Buccleuch, Smith spent over two years travelling through France and Switzerland. In Paris, he met the leading intellectuals of the age: Voltaire in Geneva, d’Alembert and Helvetius in the salons, and — most consequentially — François Quesnay and the Physiocrats, who believed that all wealth derived from land and agriculture. Smith admired their systematic thinking but rejected their conclusions. The encounter crystallised his own theory: wealth came not from land alone but from labour and the freedom to exchange its products.
The Wealth of Nations
Published on 9 March 1776, An Inquiry into the Nature and Causes of the Wealth of Nations was the culmination of a decade of solitary work. In five books and over nine hundred pages, Smith laid out a comprehensive theory of how economies function: the division of labour creates productivity, self-interest drives exchange, free markets allocate resources more efficiently than government direction, and nations grow rich not by hoarding gold but by expanding production. The book was an immediate success. Charles James Fox quoted it in Parliament within months. Within a generation, it had reshaped the economic policy of Britain and the world.
Timeline
Born in Kirkcaldy
Baptised on 5 June 1723 in Kirkcaldy, Fife, a small Scottish trading town on the Firth of Forth. His father, a solicitor and comptroller of customs, had died five months earlier. Smith was raised by his mother, Margaret Douglas, to whom he remained devoted for life. As a child of about four, he was briefly kidnapped by a band of travellers but was quickly recovered — an incident his biographers never tire of noting.
Enters Glasgow University
At fourteen, Smith enrolled at the University of Glasgow, where he studied under Francis Hutcheson, the charismatic professor of moral philosophy whose lectures on natural jurisprudence, ethics, and political economy planted the seeds of Smith’s later work. Hutcheson taught in English rather than Latin — a radical choice — and his emphasis on sympathy as a moral foundation deeply influenced Smith’s thinking.
Scholarship to Oxford
Won a Snell Exhibition to Balliol College, Oxford, where he studied for six years. Smith found Oxford stifling: the professors did little teaching, the curriculum was stale, and he was once reprimanded for reading Hume’s <em>Treatise of Human Nature</em> — a book the dons considered dangerous. He later wrote in <em>The Wealth of Nations</em> that Oxford’s endowments had made the professors lazy. The criticism was drawn from lived experience.
Edinburgh Public Lectures
Returned to Scotland and began delivering public lectures on rhetoric and belles-lettres in Edinburgh, sponsored by Lord Kames. These lectures introduced Smith to the Edinburgh literati and, crucially, to David Hume, who became his closest intellectual companion. The two men would exchange ideas, manuscripts, and arguments for the next twenty-eight years.
Professor at Glasgow
Appointed Professor of Logic at the University of Glasgow, and the following year transferred to the more prestigious Chair of Moral Philosophy. For the next thirteen years, Smith lectured on ethics, jurisprudence, rhetoric, and political economy. His students adored him. His lectures on the division of labour and the workings of markets became the scaffolding of <em>The Wealth of Nations</em>.
The Theory of Moral Sentiments Published
Smith’s first major work argued that human morality is grounded in sympathy — the ability to imagine ourselves in another’s position. It introduced the <em>impartial spectator</em>, the internalised moral judge. The book made Smith famous across Europe. Voltaire praised it. Hume celebrated it. It remains a masterpiece of moral philosophy, often overshadowed by its more famous successor but never surpassed in its psychological insight.
The Grand Tour Begins
Resigned his Glasgow chair to serve as tutor to Henry Scott, the young 3rd Duke of Buccleuch, on a Grand Tour of France and Switzerland. The salary — £300 per year plus a pension for life — was far more than his university income. In France, Smith met Voltaire, Quesnay, Turgot, d’Alembert, and the leading Physiocrats. The conversations in Paris crystallised his economic thinking and gave him the intellectual confidence to write <em>The Wealth of Nations</em>.
The Wealth of Nations Published
Published on 9 March 1776 by William Strahan and Thomas Cadell in London. The first edition sold out within six months. Charles James Fox quoted it in Parliament. Prime Minister Lord North adopted several of its policy recommendations. Smith had written the founding text of modern economics — though he would not have used that word. To him, it was a branch of moral philosophy: the study of how people prosper when left free to pursue their own interests within a framework of justice.
Key Figures
David Hume
The great philosopher and historian was Smith’s dearest companion for nearly thirty years. They met in Edinburgh around 1750 and forged a friendship built on intellectual rivalry, mutual admiration, and deep personal affection. Hume read drafts of <em>The Theory of Moral Sentiments</em> and urged Smith to finish <em>The Wealth of Nations</em>. When Hume was dying in 1776, Smith visited him in Edinburgh and later wrote a controversial account of Hume’s serene, cheerful death — controversial because Hume was an open sceptic and died without religious consolation. Smith called him ‘the most nearly perfect character I have ever known.’
François Quesnay
The physician to Louis XV and founder of the Physiocrat school of economics, Quesnay argued that all wealth derived from agricultural production and that manufacturing was ‘sterile.’ Smith met Quesnay in Paris during the Grand Tour and was deeply impressed by his systematic approach to economic analysis — particularly the <em>Tableau économique</em>, a pioneering model of how wealth circulates through an economy. Smith later said he would have dedicated <em>The Wealth of Nations</em> to Quesnay had the Frenchman not died before its publication. But Smith rejected the Physiocrats’ core claim: labour, not land, was the true source of wealth.
The Legacy of Adam Smith
Adam Smith never saw himself as an economist. The word did not exist in his lifetime. He was a moral philosopher who believed that understanding human nature — our sympathies, our self-interest, our instinct for exchange — was the key to understanding how societies prosper. The Theory of Moral Sentiments asked how we judge right from wrong. The Wealth of Nations asked how we create prosperity. Together, they form a unified vision of human life in society.
Smith died in Edinburgh on 17 July 1790. He ordered most of his unpublished manuscripts burned. What survived — two books and a handful of essays — was enough to reshape the world. Every debate about free trade, taxation, regulation, and the proper role of government begins where Smith began: with the observation that ordinary people, pursuing their own interests in open markets, produce outcomes that no central planner could design.
