In a new and updated edition of this classic textbook, Henry William Spiegel brings his discussion and analysis of economic thought into the 1990s. A new introductory chapter offering an overall view of the history of economics and a bibliographic survey of the economic literature of the 1980s and early 1990s, have been added. Maintaining the link between economics and the humanities, Spiegel's text will continue to introduce students to a wide range of topics in the history of economic thought.
