My second consecutive non-fiction book, and it's another (popular) science book - not always my best subject. This sounded pretty interesting and did not disappoint. The subjects and details are easy enough for a non-science type like me to follow and understand and the writing flows smoothly, easy to read, and often humorous. (Example: "Intelligence, like irony or daylight-saving time, is something most people have a basic grasp of but struggle to explain in detail.") And how can you not love a book with a chapter titled "We Have Nothing to Fear But Fear Itself - and Clowns"? Actually, I really gained a lot from this chapter, as I have a couple of very powerful phobias, and have recently been suffering from anxiety and occasional panic attacks. Burnett covers a lot of ground in the book: memory, fear, intelligence, personality, how the senses work and are intertwined (fascinating stuff), and mental problems, among other things. Nothing is gone into in great depth, and we get just a basic discussion on any of these topics, but that's exactly what the book presents itself as. And, as I said, Burnett's writing is fun to read. (Example #2, on the subject of motivation: "Sex is a very powerful motivator. For proof of this, see anything ever.") If I had a criticism of the book, it would be that the final chapter ("When the Brain Breaks Down") deals with mental disorders: depression, nervous breakdowns, drug addiction, hallucinations and delusions. Important stuff, to be sure, but as the final chapter, it closed the book on a downer note. A concluding section (other than the one-line "afterword" presented) would have been appreciated.
