In this book we are trying to illuminate the persistent and nag- ging questions of how mind, life, and the essence of being relate to brain mechanisms. We do that not because we have a commit- ment to bear witness to the boring issue of reductionism but be- cause we want to know more about what it's all about. How, in- deed, does the brain work? How does it allow us to love, hate, see, cry, suffer, and ultimately understand Kepler's laws? We try to uncover clues to these staggering questions by con- sidering the results of our studies on the bisected brain. Several years back, one of us wrote a book with that title, and the ap- proach was to describe how brain and behavior are affected when one takes the brain apart. In the present book, we are ready to put it back together, and go beyond, for we feel that split-brain studies are now at the point of contributing to an understanding of the workings of the integrated mind. We are grateful to Dr. Donald Wilson of the Dartmouth Medi- cal School for allowing us to test his patients. We would also like to thank our past and present colleagues, including Richard Naka- mura, Gail Risse, Pamela Greenwood, Andy Francis, Andrea El- berger, Nick Brecha, Lynn Bengston, and Sally Springer, who have been involved in various facets of the experimental studies on the bisected brain described in this book.
