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.

"A landmark new book...It tells a story you need to hear, of where we live now."—Bryan Appleyard, Sunday Times

"A very remarkable book...McGilchrist, who is both an experienced psychiatrist and a shrewd philosopher, looks at the relation between our two brain-hemispheres in a new light, not just as an interesting neurological problem but as a crucial shaping factor in our culture ...splendidly thought-provoking...I couldn't put it down."—Mary Midgley, The Guardian
