A book that says "we are well advanced" into the next century is apt to contain other sweeping statements, and Professor Drucker's latest meets that expectation. With the help of some idiosyncratic history, he pushes to extremes some familiar ideas about the end of ideology, the burden of arms and the limits of government. He puzzles the reader by insisting that no one believes anymore in "salvation by society" while finding great promise in "a pluralism of single-purpose organizations." As always, Drucker is provocative and adept at using data to upset accepted ideas. He is at his best when dealing with matters of organization, management and the inadequacy of mainstream economics.
