In the seventeenth century, the philosopher Spinoza examined the role emotion played in human survival and culture. Yet hundreds of years and many significant scientific advances later, the neurobiological roots of joy and sorrow remain a mystery. Today, we spend countless resources doctoring our feelings with alcohol, prescription drugs, health clubs, therapy, vacation retreats, and other sorts of consumption; still, the inner workings of our minds-what feelings are, how they work, and what they mean-are largely an unexplored frontier. With scientific expertise and literary facility, bestselling author and world famous neuroscientist Antonio Damasio concludes his groundbreaking trilogy in Looking for Spinoza, exploring the cerebral processes that keep us alive and make life worth living.
