Professor Antonio Damasio reassesses a history of philosophy and science that has long valued rationality over emotion

In the centuries since Descartes famously proclaimed, 'I think, therefore I am,' science has often overlooked emotions as the source of a person's true being. Even modern neuroscience has tended until recently to concentrate on the cognitive aspects of brain function, disregarding emotions. This attitude began to change with the publication of Descartes' Error. Antonio Damasio challenged traditional ideas about the connection between emotions and rationality. In this wonderfully engaging book, Damasio takes the reader on a journey of scientific discovery through a series of case studies, demonstrating what many of us have long suspected- emotions are not a luxury, they are essential to rational thinking and to normal social behaviour.
