Summary: Some interesting points, but disappoints
Sam Harris has a propensity for intriguing thought, however, that hallmark is not quite there in this work. He makes a few interesting philosophical points, especially regarding consciousness, but doesn’t seem to clearly define Spiritualism or even support why it’s worth pursuing. The book should perhaps have been titled Mindfulness: Meditation for the Empirical Mind.
The book is mostly about meditation and the goal to eliminate your concept of self. Again, there’s no support for why anyone should do this, except the watery assertion that you may be happier if you did. There’s plenty of plain, Harris-esque rejections of the wacky guru system of the East and equally fair acceptance of results based meditations. Some of these results are provocative, but fall short on pragmatism. I found myself intellectually stimulated, wanting to try what Harris had, but ultimately returned to that pre-skepticism state where the observational truths to be found are deemed irrelevant because of a lack of perceived usefulness, even if assumed true.
