Overview

This groundbreaking work explores the profound differences between the brain's two hemispheres and their impact on culture and society. McGilchrist argues that the left hemisphere, the 'emissary,' has increasingly dominated Western thought, overshadowing the right hemisphere, the 'master.'

The book delves into neuroscience, psychology, philosophy, and history to reveal how this hemispheric imbalance has shaped Western civilization's development. It challenges conventional views by emphasizing the right hemisphere's role in holistic perception and meaning.

McGilchrist's thesis suggests that the left hemisphere's analytical and reductionist approach has led to a fragmented worldview, while the right hemisphere fosters connection, context, and empathy. This tension influences art, science, politics, and culture, offering a new lens to understand human experience.
