Praise for The Age of Heretics "A remarkable job of showing how revolutionary change in management originated. These are no mere 'currents of change,' but rather a thundering waterfall of intellectual and moral forces reshaping business." --Peter Senge, author, The Fifth Discipline and coauthor, The Necessary Revolution "Any twenty-first-century leader interested in creating the organizations of the future will find this book compelling. Art Kleiner lays out the evolution of the most significant management tools, theories, and concepts in a very accessible manner." --Ram Charan, advisor to CEOs and author, Leaders at All Levels and The Game Changer "The extensively revised and updated edition of The Age of Heretics is long overdue. Kleiner offers a brilliant synthesis of business history, thought leadership, and power politics." --Robert Morris, management consultant and business book reviewer for Amazon, Borders, and others "Art Kleiner has uncovered a kind of secret history that links the medieval monastic orders, the counterculture of the sixties, and the key agents of corporate change in the modern world. I think it's a landmark for people inside and outside the most influential institution of the modern age--the corporation." --Howard Rheingold, author, Virtual Reality, Virtual Communities, and Tools for Thought "Corporate change continues to accelerate these days unaware of its own history. Art Kleiner's lucid account shows how the revolution began in the ideas and passions of a handful of revolutionaries." --Stewart Brand, founder, Whole Earth Catalog and Long Now Foundation "The Age of Heretics is a primer of great interest, one that will move people within organizations to widen their sense of the possible." --Doug Carlston, founder of Broderbund Software and chairman, Public Radio International
