The modern world is forcing us to understand emotion in order to cope with new problems such as road rage and epidemic levels of depression, as well as age-old problems such as homicide, genocide and racial tension. At the same time, scholarly research is leading us to appreciate how emotion helps us to understand and transcend our selfish interests, to connect with others, to feel what is just and moral, and not just think it, and to construct societies and cultures that govern our joint efforts. This book draws upon scholarly research to address, explain and legitimize the role that emotion plays in everyday interaction and in many of the pressing social, moral, and cultural issues that we face today.
