I had a hard time with this mainly because it became clear early on that I lack the background in philosophy the author has—and assumes the reader has, too. I enjoyed the listen, overall, but I wish his chapter conclusions would have been more like summaries and reviews since it felt like a textbook in places. I feel like I’ve walked away from the book with a decent sense of how the two hemispheres are connected and how the dominance of the left hemisphere over the last 500+ years in the West has cost us some things. But much of the detail and the more abstract ideas were lost on me since it was heady and just kept coming. I know my lack of understanding doesn’t negate the good writing and clarity for better prepared readers, so I don’t want to artificially lower the book’s rating just because I wasn’t the best audience for it. 3.5 feels like a fair compromise between my confusion and understanding, and the quality of the research and writing, in general.
