With an astonishing unity of inspiration that serves as a counterbalance to the richness and variety of his themes and positions, Albert O. Hirschman, great political economist of our time, introduces us to the study of Western Europe, the United States and Latin America. From his own memories of the fascist period retold on the occasion of his honorary degree to two previously unpublished writings on the origins of European integration, from a group of illuminating essays on the contemporary economic and political realities of developed Western countries to a selection of texts on South America containing the provisional balance sheet of long experience, this is an intellectual lesson in the truest sense. Through his original way of penetrating the realities of our time, the author unveils a series of concrete issues and new and unlikely ways forward, constructing a tenacious and possibilist scientific pathway aimed at the unstinting encouragement of mutual understanding, economic and civic growth, and the democratic development of three continents.
