In this book we are trying to illuminate the persistent and nagging questions of how mind, life, and the essence of being relate to brain mechanisms. We do that not because we have a commitment to bear witness to the boring issue of reductionism but because 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 considering the results of our studies on the bisected brain.
