As a reference book on postmodernism, this is a great. As a piece of art on postmodernism, it is also a triumph. As an introduction, however, it is completely and utterly useless. If you want to begin to understand the ideas in this book, pick up a "Teach Yourself Postmodernism"- far superiour as an introduction, but it misses out the most recent developments, and is not nearly so fascinating. Until then, this book serves an a labrynthine novelty- afterwards, it becomes a very useful and elegant reference book.
Possibly the only book I've ever read to jump from 1 to 5 stars on second reading.
