Emotion is at the centre of our personal and social lives. To love or to hate, to be frightened or grateful is not just a matter of how we feel on the inside: our emotional responses direct our thoughts and actions, unleash our imaginations, and structure our relationships with others. Yet the role of emotion in human life has long been disputed. Is emotion reason?s friend or its foe? From where do the emotions really arise? Why do we need them at all? In this accessible and carefully argued introduction, Carolyn Price focuses on some central questions about the nature and function of emotion. She explores the ways in which emotion contrasts with belief and considers how our emotional responses relate to our values, our likes and our needs. And she investigates some of the different ways in which emotional responses can be judged as fitting or misplaced, rational or irrational, authentic or inauthentic, sentimental or profound. Throughout, she develops a particular view of emotion as a complex and diverse phenomenon, which reflects both our common evolutionary past and our different cultural and personal histories. Engagingly written with lots of examples to illuminate our understanding, this book provides the ideal introduction to the topic for students and scholars and anyone interested in delving further into the intricate web of human emotion.
