Book excerpt: 'Almost 150 years after their major works were published Darwin and Marx stand alone as the premier theorists of the evolution of complex living systems. Hodgson's unique contribution in these essays is to capture the spirit of these two great thinkers in their ability to see universal principles in particular contextual frameworks. Using an evolutionary and institutional approach to examine a variety of theoretical issues Hodgson avoids both the postmodern disease of extreme relativism and the rigidity of insisting on "one true religion" for economic theory. This book is a major contribution to the current revolution in economic theory.' - John M. Gowdy, Rensselaer Polytechnic Institute, US Economics in the Shadows of Darwin and Marx examines the legacies of these two giants of thought for the social sciences in the twenty-first century.
