I have an old book of his ("The Wisdom Of Insecurity"). It's an ok read, with a few useful insights here & there, but there also are some quite antiquated ideas & concepts also. One such idea runs in direct opposition to an idea by eckhart tolle in another book i have ("The Power of Now"). Watts talks of how man is trying to separate himself from his environment & experiences (ie experiences & experiencier of those experiences), and that peace of mind will never be reached whilst striving for that. What he's saying is that we are our experiences, and that's all we are; there is no consciousness or "i" experiencing the world around us. But tolle says that you are not your mind (ie that there's a separate real "i" to the surface "me" (the mind & its perceptions of experiences)). In summary then, watts says that there is no observing consciousness, while tolle says there is. Personally, i believe in tolle's version. But watt's stuff is around 50 years old now, so its no wonder it seems outdated & innaccurate in parts.
