I found this a very enjoyable book, raising questions about the relationship between mind and body. He looks into what he considers to be (at least one of) Decarte's major error that deeply impacts modern society: the Dualistic perception of the separation of mind and body. The author makes his case for a wholistic view in which the mind and body are one, deeply integrated system. This system admitedly has various sub-systems of which that which we talk of as mind and body are two, but which feed, support and deeply influence each other. The author admits that he is putting forth a hypothosis and there are many areas that need research to validate, but his perspective seems entirely realistic to me.

Towards the end of the book, he looks a little into what this separation between mind and body means for how we understand ourselves and how our medical techology has grown and evolved, suggesting that for all it's successes, the (imaginary?) gulf between the mind and body sets a limit to the successes of modern medicine, and to our ability to truely understand who and what we are as humans.
