This is a book about a range of emotional experiences that are often regarded or characterized as ’negative’, ’disturbing’ or ’dark’ as contrasted with emotions that are ’positive’, pleasant’ or ’light’. Each chapter in the book is devoted to introducing different ‘dark emotions’ such as disappointment, betrayal, worry, regret, resentment and alienation and seeks to show - through conceptual, theoretical and empirical examples - how these emotions influence peoples’ lives and their relations to self, others and society.
