Nicholas Philipson talked about his book Adam Smith: An Enlightened Life (Yale University Press, 2010), an intellectual biography of Scottish philosopher Adam Smith (1723-1790). The author examines Smith's philosophical and economic thinking and explores not only his best known work, The Wealth of Nations, which popularized the notion of the "invisible hand" of the market and shaped modern economics, but also Smith's other great work, The Theory of Moral Sentiments. Nicholas Philipson was joined in conversation by James Otteson, author of Adam Smith's Marketplace of Life. They also responded to questions from members of the audience at this Cato Institute Book Forum in Washington, D.C.
