Adam Smith is the best known among economists for his book, The Wealth of Nations, often viewed as the keystone of modern economic thought. Others, often heterodox economists and social philosophers, on the contrary, focus on Smith's Theory of Moral Sentiments, and explore his moral theory. This work treats these dimensions of Smith's work as elements in a seamless moral philosophical vision, demonstrating the integrated nature of these works and Smith's other writings. Although many practitioners today see the study of Smith as an antiquarian exercise, this book weaves Smith into a constructive critique of modern ecnomic analysis (engaging along the way the work of Nobel Laureates Gary Becker, Amarty Sen, Douglass North, and James Buchanan) and builds bridges between that discourse and the other social sciences.
