This book belongs to those that contain extremely competent and valuable information, especially from chapter 2 onwards. The author has pioneered experimental research in detectable aspects of consciousness, and reviews ideas, experiments, techniques and results in a compelling way. Chapter 1 introduces the importance of the topic using the narrative scheme "until now we knew nothing (and there was religion roaming free), but finally we are going to understand something thanks to science". To be fair, there is no open claim for materialism and atheism. The author is also very emphatic in stressing that progress has come from identifying a measurable manifestation of consciousness, called "conscious access", and that this is not all there is to consciousness. A mature believer will not feel excessive pain passing through those lines, though they may be a bit unpleasant. And maybe it is worth while moving on because the rest of the book is very informative. After all, much worse materialism is rampant in a good fraction of the popular literature on neuroscience, and this book has the advantage of having been written by a protagonist whose competence cannot be questioned.
