This book is a strange mixture of oppositions; populist style and complex material, originality and repetition, astounding insight and blundering oversight. Wilber's insights into postmodernism, Freudian psychology and spiritual development are among the most original of the 20th century, but some authors he has obviously misread and others completely misunderstood, esp. Jung and various Western philosophers, and his claims to be a Buddhist are flatly contradicted by his holon theory, which is completely antithetical to the philosophical core of Buddhist teachings. His style, when dealing with complex material, is often very clear and precise, but the introduction and various individual paragraphs are full of misleading metaphors and populist literary techniques which give a sometimes sickly and pompous impression of Wilber. Certainly read this and appreciate it, but be careful not to be always taken in by his persuasive style, and remember to constantly question him.
