Albert Hirschman, who died late last year, was one of the most interesting and unusual thinkers of the last century. An anti-utopian reformer with a keen eye for detail, Hirschman insisted on the complexity of social life and human nature. He opposed intransigence in all its forms. He believed that political and economic possibilities could be found in the most surprising places. Hirschman’s work changes how you see the world. It illuminates yesterday, today, and tomorrow. His categories become your categories.
