"Critical Path traces the origins and evolution of humanity's social, political, and economic systems from the obscure mists of prehistory, through the development of the great political empires, to the vast international corporate and political systems that control our destiny today, to show how we got to the present situation and what options are available to man. With his customary brilliance, extraordinary energy, and unlimited devotion, Bucky Fuller shows how mankind can survive, while showing how each individual can respond to the unprecedented threat we face today"--Jacket.
