I was expecting a complete wishy-washy new-agey mosaic of pseudo-science, pseudo-history, pseudo-scholarship; but actually the scholarship and historical information in this book were pretty darn good.
It's a good introduction to ancient Chinese philosophy, the context of Zhuangzi and Laozi. The philosophy isn't watered down too much, and fortunately (thanks no doubt to Chad Hansen's contribution) it's not mixed in with unrelated stuff from the Upanishads or anything like that.
There is a misprint on the back, "ying-yang" which must be slang for the padding surrounding one's gluteus maximus; inside the book the spelling is correct. The explanation of yin-yang is also correct and simple.
I would've wanted a lot more information on religious Taoism: information about modern movements and so on. Which deities are most commonly worshipped in Taiwan, which in Hong Kong, which in Beijing? And, how are they worshipped? I'd like information about Taoist pilgrimages, Taoist sacred places, and so on. The book doesn't touch any of that: minus one star.
Also, the bit on quantum physics could be greatly, greatly improved. Maybe they could've asked a few grad students at a physics dep't for commentary? It would have greatly helped: minus one star.
However, I just couldn't give the book 3 stars; the chapters on politics and ecology were surprisingly good, the internet links are too helpful, and as I said earlier the explanation of ancient Chinese philosophy was too good. So, maybe there's a little grade inflation here.
In sum, it's a good introduction to Taoism, and it'll prepare you to move on to deeper stuff, and help you find it.
If, like, you're already a Taoist immortal or something, this book isn't for you, and you can't really criticize it for that. I'd expect you to realize that already.
