The Theory of Moral Sentiments is a 1759 treatise by Adam Smith that develops a framework for moral judgment based on human sympathy and social approbation. It situates individual moral reasoning within the context of interpersonal relations and broader civic life, influencing debates in moral philosophy, political economy, and moral psychology. The work engaged contemporaries across the Enlightenment and later informed figures in utilitarianism, political theory, and economic thought.

Background and Context

Smith wrote the work in the milieu of the Scottish Enlightenment alongside contemporaries such as David Hume, Thomas Reid, Francis Hutcheson, James Boswell, and William Robertson. Intellectual networks linked Smith to institutions like the University of Glasgow and to patrons and interlocutors in Edinburgh, London, and the courts of George III. Debates over natural law involving figures like Samuel Johnson, Jean-Jacques Rousseau, and Voltaire framed the broader continental context. The book emerged amid developments in moral philosophy traced through works by Aristotle, Thomas Hobbes, John Locke, Baruch Spinoza, and Immanuel Kant, and amid public discussions influenced by periodicals such as The Spectator and societies like the Royal Society of London.

Summary of Key Arguments

Smith proposes that moral approval arises from an imagined impartial spectator that mediates between agents and observers, echoing themes in the writings of Plato, Cicero, and Seneca. He argues that sentiments such as sympathy, benevolence, and resentment are formative of moral norms, positioning these against jurisprudential schools represented by Hugo Grotius and Cesare Beccaria. Smith advances a theory of natural sentiments shaped by social experience and refined by reflective judgment, engaging analytic precedents in the work of Gottfried Wilhelm Leibniz and empirical approaches associated with Francis Bacon and John Locke. His account distinguishes between praise and blame, private prudence and public justice, and treats distributive concerns in ways that would later intersect with writings by Jeremy Bentham, John Stuart Mill, and Henry Sidgwick.

Moral Psychology and Sympathy

Central to Smith’s moral psychology is the notion that observers project themselves into the feelings of others, an operation comparable to explanatory strategies in the writings of David Hume and to affective theories found in Aristotle’s ethical psychology. He analyzes the mechanics of sympathy in relation to examples involving actors such as merchants, artisans, and statesmen—figures comparable to those discussed in correspondence with William Pitt the Younger and Lord Kames. Smith examines biases like partiality toward friends and prejudice against strangers, resonating with later investigations by Charles Darwin on social emotions and by Sigmund Freud on conscience. The impartial spectator functions as a regulative ideal akin to public reason in debates involving Baron de Montesquieu and Alexis de Tocqueville.

Virtue, Prudence, and Justice

Smith distinguishes among virtues: prudence governs self-regarding conduct, benevolence governs beneficence, and justice constrains interference with others’ possessions and rights, intersecting conceptually with the legal theories of William Blackstone and the political theories of John Locke. He treats justice as foundational for social order, connecting his analysis to institutional concerns debated in contexts like the Glorious Revolution and reforms attributed to Robert Walpole. Smith’s treatment of prudence anticipates later discussions by Adam Ferguson and economic reflections in his own later work, linking moral dispositions to commercial life observed in ports such as Glasgow and Liverpool.

Reception and Influence

The book influenced a wide range of thinkers across Europe and America: Immanuel Kant acknowledged moral reasoning debates of Smith’s era, while proponents like Jeremy Bentham, John Stuart Mill, Karl Marx, Max Weber, and Friedrich Hayek engaged Smith’s ideas in the context of political economy and ethics. Nineteenth-century commentators including James Mill, Thomas Carlyle, John Ruskin, and Herbert Spencer debated his legacy; twentieth-century scholarship engaged Smith through figures such as Alfred Marshall, Lionel Robbins, Friedrich Hayek (again), and John Maynard Keynes. Institutional audiences at the University of Oxford, University of Cambridge, and Harvard University have produced extensive commentary, and modern interdisciplinary work connects Smith to research by Daniel Kahneman, Amartya Sen, Elinor Ostrom, and Robert Putnam.

Editions and Publication History

First published in 1759 by A. Millar in London, the work underwent multiple editions during Smith’s lifetime and posthumously revised printings often paired with his later book, An Inquiry into the Nature and Causes of the Wealth of Nations. Notable editors and commentators include D.D. Raphael, A.L. Macfie, and historians associated with presses at Oxford University Press and Cambridge University Press. Manuscript collections of Smith’s letters and notes are held in archives connected to the University of Glasgow, the National Library of Scotland, and the Bodleian Library.
