This Companion of nineteen essays, accompanied by the editor's 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. His earlier work in moral philosophy, The Theory of Moral Sentiments receives significant consideration and the contributors also discuss important connections and insights into the sort of economics that Adam Smith is more widely known for in his Wealth of Nations. This book is distinguished from other collections of essays on Adam Smith in that all of the contributors are economists, and the coverage is determined by the interests of contemporary economists and scholars in the history of economic thought. A wide audience will find this Companion of great value and interest, including economists, the general economics profession, political scientists and political theorists, and philosophers with an interest in Adam Smith's work as well as historians of economics. Advanced undergraduate and post-graduate students in these fields will also warmly welcome the book.
