"Thought provoking" is a term that's been abused and debased into shallow, lukewarm praise-- like calling a piece of art "interesting". Few books actually manage to demand a serious response from the reader; to attack us into interacting, to force us to really THINK. T.A.Z. does that. If you like that sort of thing - you know who you are - read it.
It seems to me that many people, including some reviewers here, have grossly misunderstood this wonderful little book. I will say if you are very closed-minded or extremely sensitive to offense, you may have a hard time. All the more reason to read it. T.A.Z. collects various writings (ranging in length from essays to slogans) first published throughout the 1980s by a mysterious Brooklyn-based anarchist; in fact, "Hakim Bey" is an author-character invented by writer Peter Lamborn Wilson for a wide variety of purposes: sometimes to voice opinions of Wilson's, sometimes as an antithetical strawman to Wilson's own perspective, sometimes to go further out on a limb in a line of thought than Wilson is comfortable to go himself, sometimes to scare people, to seduce them, to desensitize, sensitize, expose outrageous truths, craft subtle lies (some embedded with hidden truth, some maybe not) and to generally be radical/extremist- culturally politically and philosophically. Which of Bey's statements fall into what categories is not always clear, to the frustration of some and fascination of others (such as myself). Ultimately it is impossible to tell which of the author's statements are "real", ie perspectives truly held by Wilson, but that doesn't matter. The point is more to stimulate a response in the reader than to actually proselytize. That said, there is plenty of genuine info here: data, analysis, quotations, street reportage, etc.
People tend to conflate Wilson and Bey. Writings published under Wilson's own name, which tend to be more reasoned and academic, demonstrate something of a contrast. Bey's constant quotations of Nietzsche, who famously practiced similar authorial cons, and his conflicting/competing perspectives are also major clues. Futhermore, it is rumored that there were several silent contributors to the Bey material, one of whom was Robert Anton Wilson, a close friend of PLW's. The bottom line is that, like the bible, this book is LITERATURE. Treated as such, it is an incredible head-trip and potentially life-changing. I highly recommend TAZ to anyone interested in radical change, in consciousness or other. I'd also point fans towards a similar book from many years before: Thundersqueakby Angerford & Lea (aka Ramsey Dukes, which is yet another pseudonym). Read them carefully!
