Drawing broadly on science, philosophy, politics, and wisdom teachings, James Olson offers a holistic look at how the brain's division into distinct hemispheres results in two divergent perspectives on our experience. These contrasting perceptions of the world, in turn, become a direct cause of the crippling polarizations we see today in gender relations, politics, and public policy—leading to culture wars and even modern warfare. Noting that one side of the brain always tends to dominate the other, Olson offers novel methods to minimize this imbalance.
