In this intellectual biography, the economic historian Michele Alacevich explores the development and trajectory of Hirschman’s characteristic approach to social-scientific questions. He traces the many strands of Hirschman’s thought and their place in his multifaceted body of work, considering their limitations as well as their strengths. Alacevich puts Hirschman’s ideas into context, following his participation in the major intellectual and political debates of his times. He examines Hirschman’s pioneering work in development studies and his analyses of social change, the history of capitalism, and the workings of democracy alongside his activities in the postwar reconstruction of Europe and economic development in Latin America. A compelling intellectual portrait of a profoundly distinctive thinker, this book also reflects on Hirschman’s legacy and lasting influence.
