Recording of a lecture delivered on September 5, 2025, by Professor Thomas Merrill as part of the Formal Lecture Series. Thomas Merrill is an associate professor for American University’s School of Public Affairs, and the associate director for the university’s Political Theory Institute, with research interests in political science and governance. He previously served on the President’s Council on Bioethics, and his most recent book, Hume and the Politics of Enlightenment, was the winner of the Delba Winthrop Award for Best Recent Work in Political Philosophy.

Professor Merrill offers the following introduction to his lecture: "Smith’s Theory of Moral Sentiments seems to offer a morality perfectly suited for bourgeois modernity: secular, sympathetic, and based on our transparency to each other. Yet upon examination, Smith’s moral world is shot through with deception and self-deception on several levels. This lecture uses Smith’s treatment of deception and self-deception to uncover the narrative structure of the Theory of Moral Sentiments and highlights the idea of generative errors—mistakes and deceptions that have unintended but positive consequences—as a key theme of Smith’s thought."
