This book represents the painstaking effort of a great mind. An excrucriatingly detailed critical review of the economic literature pre-dating Marx is undertaken. Anyone seeking to understand the history of economics must carefully review this epic work. Historians too, will appreciate the extensive treatment of the contexts into which generations of economic ideas were born. Marx's revolutionary new theory of class emerges clearly from his critical reading of the great and not-so-great works which provided the foundation on which his break-throughs were built.
