July 4, 2026 marks the 250th anniversary of the Declaration of Independence and the colonists’ claim to “life, liberty, and the pursuit of happiness.” The year 1776 also recalls a quieter but significant anniversary. Adam Smith published An Inquiry into the Nature and Causes of the Wealth of Nations, giving the modern world a language for thinking about markets, productivity, and prosperity.
Before Smith wrote about markets, though, he wrote his The Theory of Moral Sentiments. There he explored sympathy—our capacity to enter into the feelings of others—and the moral discipline of what he called the “impartial spectator.” That discipline was not mere politeness. It involved learning to govern one’s passions, judge one’s conduct as others might judge it, and become fit for life among free and equal persons. Smith’s insight was that liberty depends not only on institutions and incentives, but also on habits of self-command and regard for others that no market can create on its own. He understood that commercial society rested on moral and social foundations it did not itself create.
A free society must ask not only how wealth is produced, Smith teaches us, but how it is shared, accessed, and made usable in ordinary life. Today, those questions are relevant to one of the biggest problems we face: what some have called “the loneliness crisis.” Revisiting Smith’s writings can help demonstrate that this crisis of disconnection is not merely a public-health concern or a matter of loneliness, but a civic and cultural problem with implications for self-government.
That requires attention not only to economic and human capital, but also to social wealth: the relationships, habits, associations, friendships, local loyalties, and institutions that help people find belonging, weather hardship, and turn learning into opportunity. Social scientists often call this social capital, but the two ideas point to much the same reality. If economic wealth describes a nation’s productive assets, social wealth describes the civic and moral reserves that make freedom workable and prosperity widely accessible.
