Adam Smith

Biography

Adam Smith was born on June 5, 1723, in the small fishing town of Kirkcaldy, on the Firth of Forth in eastern Scotland. His father, also named Adam Smith, was a lawyer, civil servant, and comptroller of customs who died shortly before his son was born. Smith was raised by his mother, Margaret Douglas, with whom he maintained a close and devoted relationship throughout his life. The circumstances of his birth — fatherless, raised by a strong and loving mother in a modest provincial town — shaped a temperament that contemporaries described as gentle, absent-minded, and deeply bookish.

Smith received his early education at the burgh school in Kirkcaldy, where he proved an exceptional student. At fourteen, he entered the University of Glasgow, where he studied moral philosophy under Francis Hutcheson, one of the leading figures of the Scottish Enlightenment. Hutcheson's emphasis on human sociability, moral sense, and the possibility of a natural moral faculty made a lasting impression on the young Smith. In 1740, Smith won the Snell Exhibition, a scholarship that sent him to Balliol College, Oxford, where he spent six years. He found Oxford intellectually stagnant, dominated by idle fellows who took little interest in teaching. He devoted himself to independent reading, particularly in Greek and Latin literature, and developed a distaste for the Oxford educational system that he never lost.

After leaving Oxford in 1746, Smith returned to Kirkcaldy and spent several years looking for a suitable academic position. In 1748, he began delivering public lectures on rhetoric and jurisprudence in Edinburgh, supported by the patronage of Henry Home, Lord Kames. The lectures were a success and established Smith's reputation. In 1751, he was appointed Professor of Logic at the University of Glasgow, and in 1752 he transferred to the Chair of Moral Philosophy, the position Hutcheson had once held. Smith's years at Glasgow were among the happiest and most productive of his life. He taught a curriculum that covered natural theology, ethics, jurisprudence, and political economy, and he developed many of the ideas that would later appear in his published works.

During his Glasgow years, Smith formed the most important intellectual friendship of his life: his bond with the philosopher David Hume. Smith and Hume shared a commitment to empiricism, naturalism, and the application of philosophical methods to human behavior and institutions. They corresponded extensively, and Hume's skepticism, moral psychology, and historical approach deeply influenced Smith's thought. Smith later said that Hume was the most perfectly wise and virtuous person he had ever known, and his grief at Hume's death in 1776 was profound.

Smith left academia in 1764 to accept a position as tutor to the young Duke of Buccleuch, a position that came with a substantial income for life and gave him the opportunity to travel extensively in France and Switzerland. In Paris, he met the leading French intellectuals of the day, including the physiocrat François Quesnay and the encyclopedist d'Alembert. The physiocrats' emphasis on natural economic order and the productivity of agriculture influenced his thinking, though Smith never fully adopted their system. Upon returning to Kirkcaldy in 1766, Smith spent the next decade writing his masterwork, An Inquiry into the Nature and Causes of the Wealth of Nations, published in 1776. In 1778, he was appointed Commissioner of Customs in Edinburgh, a position he held until his death on July 17, 1790.

Philosophy

Adam Smith's philosophy rests on a single, powerful insight: human beings are fundamentally social creatures whose moral and intellectual lives are shaped by their interactions with others. This insight unifies his two great works, The Theory of Moral Sentiments (1759) and The Wealth of Nations (1776), and it connects his ethics to his economics in ways that later interpreters, focused on the economic work alone, have often missed. Smith did not see himself as an economist — the discipline did not exist in his time — but as a moral philosopher investigating the conditions of human flourishing.

The foundation of Smith's moral philosophy is the concept of sympathy. By sympathy, Smith did not mean pity or compassion in the narrow sense. He meant the universal human capacity to imagine oneself in the situation of another person and to feel, by reflection, something of what that person feels. When we see someone suffering, we do not literally feel their pain, but we form an idea of what it would be like to be in their position, and this imaginative projection produces a corresponding emotion in ourselves. This capacity for sympathetic identification is, for Smith, the basis of all moral judgment. We judge our own conduct by imagining how an impartial spectator would view it, and we judge the conduct of others by the same standard. Morality is not grounded in divine command, in abstract reason, or in a special moral sense, but in the social and psychological dynamics of compassion and imaginative identification.

Smith's political economy, which later generations would call economics, is best understood as an extension of his moral philosophy into the domain of production, exchange, and distribution. He argued that the wealth of a nation consists not in its hoards of gold and silver, as the mercantilists claimed, but in the productive capacity of its people and the efficiency with which goods and services are exchanged. The division of labor, which Smith famously illustrated through the example of a pin factory, allows workers to specialize, increasing productivity and creating surplus that can be exchanged. Markets coordinate the activities of countless individuals without central direction, because each participant, pursuing self-interest, is led by the invisible hand of competition to produce what others need at prices they can afford.

The phrase "invisible hand" has been the subject of enormous misunderstanding. It does not mean, as some later economists and popularizers claimed, that self-interest always produces the best possible outcome regardless of institutional context. Smith was clear that markets require a framework of justice, law, and public goods to function properly. He supported public education, public works, regulation of banking, progressive taxation, and restrictions on monopolies. The invisible hand describes a tendency within a well-ordered commercial society, not a universal law that renders government unnecessary. Smith the moral philosopher was not the simple apostle of laissez-faire that his later reputation suggested.

Major Works

The Theory of Moral Sentiments (1759) was Smith's first book and the work he considered his most important. It grew out of his Glasgow lectures and went through six editions during his lifetime, the last substantially revised. The book opens with a deceptively simple observation: however selfish we may suppose human beings to be, there are evidently principles in our nature that interest us in the fortune of others. Smith then develops a systematic account of moral judgment based on sympathy and the impartial spectator. He analyzes virtues such as propriety, prudence, benevolence, and self-command, and he examines the influence of custom and fashion on moral judgment. The work is also a work of social psychology, exploring how human beings form moral opinions through social interaction, and how the desire for social approval shapes conduct.

An Inquiry into the Nature and Causes of the Wealth of Nations (1776) is the founding text of modern economics. In five books, Smith analyzes the division of labor, the origin and use of money, the determination of prices and wages, the accumulation of capital, the history of economic systems, and the proper role of government in a commercial society. The work is far more than a treatise on economics; it is a work of historical sociology and political philosophy, examining how commercial society emerged from feudalism, how institutions shape economic behavior, and how the pursuit of wealth interacts with the pursuit of virtue. Smith's arguments against mercantilism, for free trade, and for the division of labor transformed economic thought and laid the groundwork for classical political economy.

Smith also left substantial unpublished work, including the Lectures on Jurisprudence, which survive in student notes and reveal his approach to law, politics, and the history of institutions. His Lectures on Rhetoric and Belles Lettres show his engagement with literary criticism and communication. At his death, Smith ordered his unpublished manuscripts burned, a request his executors honored, depriving posterity of whatever those writings contained.

Key Ideas

Sympathy and the Impartial Spectator

The concept of sympathy is the cornerstone of Smith's moral philosophy. Every moral judgment, Smith argues, involves an act of imaginative identification. When we see someone in distress, we put ourselves in their place and feel something of their suffering. When we see someone joyful, we share their joy. This sympathy is not automatic or perfect — we never fully inhabit another's experience — but it is sufficient to ground moral life. We approve of conduct that the impartial spectator would sympathize with, and we disapprove of conduct that the impartial spectator would reject. The impartial spectator is not an actual person but an idealized perspective that we construct through social experience, internalizing the judgments of the communities in which we live. This framework gives Smith a naturalistic account of morality that requires neither divine revelation nor abstract rationalism.

The Invisible Hand

The invisible hand is Smith's most famous metaphor and his most misunderstood. In The Wealth of Nations, Smith observes that each individual, pursuing self-interest, is led by an invisible hand to promote an end that was no part of his intention. The butcher, the brewer, and the baker do not provide our dinner out of benevolence but from regard to their own interest, and by pursuing their own interest they produce a social benefit that no one planned. This insight does not imply that markets always produce optimal outcomes or that government should do nothing. Smith explicitly identifies situations where markets fail — monopolies, externalities, public goods, the exploitation of workers, the degradation of character that can result from repetitive specialized labor. The invisible hand describes a real and important tendency within commercial societies, but it operates within an institutional framework of law, justice, and public provision.

The Division of Labor

Smith's analysis of the division of labor is the starting point of modern economics. In the opening chapters of The Wealth of Nations, he uses the example of a pin factory to show how the specialization of tasks dramatically increases productivity. A single worker performing every step of pin production might make twenty pins a day. Ten workers, each specializing in one step, can make forty-eight thousand. The division of labor is limited by the extent of the market, because larger markets allow greater specialization. But Smith also recognized the dark side of specialization: workers who spend their entire lives repeating a few simple operations become stupid and ignorant, incapable of civic participation or moral reflection. Smith advocated for public education as a remedy — a position that places him far from the caricature of a laissez-faire ideologue.

Justice as the Foundation of Society

For Smith, justice is the one virtue that society cannot do without. Society can subsist without benevolence, but the prevalence of injustice must utterly destroy it. Justice, in Smith's usage, means refraining from injuring others — in their person, property, or reputation. It is a negative virtue: it consists mostly in abstaining from harm. But it is indispensable, because without the security that justice provides, no other goods — economic, moral, or intellectual — can be pursued. Smith distinguished between justice, which can be enforced by law, and other virtues such as beneficence, which cannot. This distinction between enforceable justice and non-enforceable virtue is one of his most important contributions to moral and political philosophy.

Famous Quotes

"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. We address ourselves, not to their humanity but to their self-love, and never talk to them of our own necessities but of their advantages."

This passage from The Wealth of Nations captures the core insight of Smith's political economy: social cooperation does not require moral perfection. Markets coordinate the activities of self-interested individuals in ways that produce collective benefits, provided the framework of justice is maintained.

"How selfish soever man may be supposed, there are evidently some principles in his nature, which interest him in the fortune of others, and render their happiness necessary to him, though he derives nothing from it except the pleasure of seeing it."

The opening lines of The Theory of Moral Sentiments establish the foundation of Smith's moral philosophy. Human beings are not, in Smith's view, merely self-interested calculating machines. They are social creatures with a capacity for compassion that is as fundamental as self-love.

Legacy

Adam Smith's legacy is enormous but deeply contested. He is universally recognized as the founder of modern economics, and The Wealth of Nations remains one of the most influential books ever written in the social sciences. His analysis of the division of labor, the price mechanism, and the self-regulating tendencies of markets shaped the development of classical political economy through Ricardo, Mill, and Marx, and continues to inform economic theory today.

But the popular image of Smith — the prophet of self-interest, the apostle of laissez-faire, the theorist who proved that greed is good — is a caricature that would have appalled him. Smith was a moral philosopher first and an economist second. He believed that commercial society could produce both unprecedented prosperity and serious moral costs, and he insisted that markets must operate within a framework of law, justice, and public provision. The recovery of the "real" Adam Smith — the thinker who placed sympathy at the center of moral life and who worried about the dehumanizing effects of the division of labor — has been one of the most important scholarly projects of recent decades.

Smith's influence extends beyond economics. His moral philosophy, with its emphasis on the impartial spectator and the social construction of moral judgment, has influenced contemporary moral psychology, behavioral economics, and political theory. The concept of the impartial spectator, in particular, has proven remarkably fertile across multiple disciplines, offering a framework for understanding how individuals navigate the tension between self-interest and social responsibility that remains relevant to debates about inequality, corporate ethics, and the moral foundations of market societies. His friendship with Hume represents one of the great intellectual partnerships in the history of philosophy, and together they defined the spirit of the Scottish Enlightenment: empiricist, naturalist, historically minded, and committed to understanding human beings as they actually are rather than as abstract reason might wish them to be.
