"In this 20th-anniversary edition of the bestselling work, Wilber takes readers on a journey from the Big Bang to the future, impressively synthesizing multiple fields of study. He organizes his material to fit its evolutionary nature, feeding off of what came before in order to provide a transformational unified theory of history. Readers will gain new perspective on what they know, or think they know, about every possible discipline. Publishers Weekly

"Ken Wilber is a national treasure. No one is working at the integration of Eastern and Western wisdom literature with such depth or breadth of mind and heart as he." Robert Kegan, Professor of Education, Harvard University Graduate School of Education, and author of In Over Our Heads

"When Ken Wilber s thought walks through your mind, the door to the next higher level becomes visible. Anyone seeking to update the wisdom traditions of their lineage needs his reality and consciousness maps. The kabbalah of the future will lean on Ken s work." Reb Zalman Schachter-Shalomi

"Ken Wilber is today s greatest philosopher and both critic and friend to authentic religion, a true postmodern Thomas Aquinas." Father Richard Rohr, Center for Action and Contemplation

"In the ambitiously titled A Brief History of Everything, Wilber continues his search for the primary patterns that manifest in all realms of existence. Like Hegel in the West and Aurobindo in the East, Wilber is a thinker in the grand systematic tradition, an intellectual adventurer concerned with nothing less than the whole course of evolution, life's ultimate trajectory in a word, everything. . . . Combining spiritual sensitivity with enormous intellectual understanding and a style of elegance and clarity, A Brief History of Everything is a clarion call for seeing the world as a whole, much at odds with the depressing reductionism of trendy Foucault-derivative academic philosophy.
