The Commentary for the third edition of this successful guide to writing has been revised and expanded in many ways to provide more support for instructors; this includes additional tasks for Units Two and Four to supplement the main text. However, the collegial tone established in previous Commentaries between Swales & Feak and instructors has been retained.

This volume contains commentaries on each of the eight units plus the two appendixes. The format for each unit includes

• a summary of the main points of the unit along with a list of topics covered.
• a synopsis of activities, divided into Language Focus sections and description of tasks.
• some general notes designed to capture the character of the unit, to indicate alternative activities, or to anticipate problems that may arise.
• detailed commentary and discussion of individual tasks, including model or sample answers where possible.

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.

From reviews of previous editions:

“The history of economic thought to end all histories of economic thought.”—Robert D. Patton, Journal of Economic Literature

“The book is in the grand tradition of the history of doctrines. It is a history of economic thought broadly conceived—and superbly written to boot. It is not to much to say that Spiegel’s book will become and remain a leading text in the field.”—Warren J. Samuels, Social Science

The author conveys the essence of an idea simply and clearly, yet in a graceful style.”—William F. Kennedy, Journal of Economic Literature
