In a book of unprecedented scope–now available in a larger format—Iain McGilchrist presents a fascinating exploration of the differences between the brain’s left and right hemispheres, and how those differences have affected society, history, and culture. McGilchrist draws on a vast body of recent research in neuroscience and psychology  to reveal that the difference is profound: the left hemisphere is detail oriented, while the right has greater breadth, flexibility, and generosity. McGilchrist then takes the reader on a journey through the history of Western culture, illustrating the tension between these two worlds as revealed in the thought and belief of thinkers and artists from Aeschylus to Magritte.
