Starting from the premise that human beings "exist wholly within nature as part of natural order in every respect," Jane Jacobs has focused her singular eye on the natural world in order to discover the fundamental models for a vibrant economy. The lessons she discloses come from fields as diverse as ecology, evolution, and cell biology. Written in the form of a Platonic dialogue among five fictional characters, The Nature of Economies is as astonishingly accessible and clear as it is irrepressibly brilliant and wise–a groundbreaking yet humane study destined to become another world-altering classic.
