The book delves into the analysis of anger as both a moral and amoral emotion. It investigates whether anger is indeed one of the basic emotions or if it is a social and linguistic construct, denoting a concept associated with the human mind. The author subjects the concept of anger to an analysis of its semantic domains, as well as a conceptual analysis regarding what it signifies and means to us. Anger is analyzed from philosophical-phenomenological perspectives, as well as from the viewpoints of cognitive sciences, evolutionary psychology, and social psychology. The significance of anger in both phylogenetic and ontogenetic development is explored. Through a deeper understanding thereof, avenues toward its better and more effective management are elucidated.
