This "Companion" of nineteen essays, accompanied with the editor's lively introduction, investigates aspects of the philosophical foundations of Adam Smith's thought as well as his economic analysis and approach to policy. The authors view Adam Smith's work as an interconnected system of thought, which incorporates both moral philosophy and economics. Adam Smith's earlier work in moral philosophy "The Theory of Moral Sentiments" receives significant consideration. The authors offer important connections and insights into the sort of economics Adam Smith is more widely known for in his "Wealth of Nations".
