Excellent overview, but sub-optimal production
Westphal's explication of the mind-body problem is as serviceable an overview as I've yet experienced (and I've read a lot). The only thing better would be a proper university lecture series. I especially appreciated the syllogistic reductions in key chapters, which helped to keep the focus on the core paradox. If you're looking for a detailed exploration of the scientific theories of consciousness, this book is not for you. You might try Dennett instead.
Where the book (and the audio) fall down, is in the production quality. The reading is peppered with odd pause points (presumably, due to re-read edits), and inconsistent pronunciations. At one point, he pronounces "quale" as "quail", and at another, as "qua-lay" (the right way), for example. In the text, there are lots of misspellings, and there was no attempt to reformat the typesetting for digital. So, where in the print edition, you'd get large-print insets of important "pull quotes", what you get in the digital edition is whole blocks of repeated text, that looks like the rest of the text. That's very confusing for a reader. Overall, I'd still give this an above-average rating, for an introductory volume.
