Beyond a World Divided

About the Book

Thinkers as diverse as C.P. Snow, J. Bronowski, and Carl Sagan have described the rift between the “two cultures” of science and the humanities as the greatest barrier to solving the many problems threatening today’s world. During the last two decades of his life, Nobel laureate Roger W. Sperry – best known for his pioneering split-brain studies that highlighted the differing aptitudes of the two hemispheres of the human brain – turned his energies to this dilemma. Sperry’s ideas about consciousness challenged the behaviorist orthodoxy that prevailed in psychology in the 1950s and ’60s, and provided a way of understanding the relationship between brain and mind that not only more accurately reflected reality, but also promised a reconciliation between the conflicting claims of hard-edged objective fact and the realm of human emotion and subjective experience. Beyond A World Divided chronicles the neuroscientist’s groundbreaking research, his efforts to refine and win acceptance for his ideas, and his struggle to advance his work despite the onslaught of the degenerative nerve disease that eventually killed him. The book concludes by surveying the debate in the psychological and philosophical communities about the impact of Sperry’s ideas – a debate which still continues.
