The deepest thinker on this subject since Darwin, Daniel Gilbert, author of the bestseller "Stumbling on Happiness," describes this book as fascinating and as an inspiring journey into the science of emotions. This carefully researched and thoughtfully written book provides insights into our emotions – what they are, where they come from, and why we have them. For anyone who has struggled to reconcile mind and heart, this book will be a treasure; it explains the science without neglecting the humanism of its subject, according to Andrew Solomon, bestselling author of "Far From the Tree" and "The Noonday Demon." When you feel anxious, angry, happy, or surprised, what is really happening inside you? Many scientists believe that emotions originate from a specific part of the brain that is triggered by the world around us. The thrill of seeing an old friend, the fear of losing someone we love – each of these emotions has its roots in our brain.
