I'm not going to add anything significant to the volumes already written in review of this opus. Examining left brain/right brain approaches and tensions, framing this in the contexts of how we live our lives, conduct ourselves and view the world and each other...and considering the impact this might have on the ways that we feel about ourselves and what we perceive and deduce about our own consciousness and life-rationale...is always going to be a big ask.
McGilchrist takes a run at all this from many angles, leaving a somewhat dazed reader grappling with the enormity of it all. His writing is clear and occasionally funny. His canvas is wide, and his brushstrokes are only firm enough for the necessary clarity when such a need arises. Elsewhere, his deftness of touch in articulating concepts and hypotheses takes the reader/listener along with him on a fascinating journey to better understanding what could make us tick.
Not a book for the faint-hearted, but rewarding for the insights and understanding gained when reading/listening to it.
