This book provides an intellectual portrait of Robert Heilbroner. It traces the development of his work and places it within the literature of economic thought. The book finds that Heilbroner is a writer of political economy in the classical sense. His work is more reminiscent of Smith or Marx than of contemporary economic theorists. Heilbroner's economics is built on a solid foundation of social psychology, evolutionary dynamics and human history. This holistic approach affords Heilbroner a wide latitude to define the economic process and the discipline that studies it.
