Utterly disappointing. It's like listening to a reasonably intelligent person talk out loud while cleaning his navel.

Watts posits all sorts of random ideas without backing them up in any form (i.e. evidence or even further thought), and there is no clear logic to the order in which he presents these ideas. I was expecting a thought-provoking question or two to rise to the surface, so I kept at it, but in the end was left with the distinct feeling that I'd just listened to a stoner with a big ego ramble on for a while.
