The chapter explores the roots and dynamics of anger, a fundamental emotion that is deeply rooted in human evolutionary history. Anger is linked to sadness, forming a complex emotional spectrum that includes both positive and negative aspects. The text discusses how anger serves as a goal-seeking and approach-oriented emotion, essential for asserting social dominance and addressing threats to one's status. It also examines the historical and cultural variations in the expression and management of anger, highlighting its role in social interactions and power dynamics. The chapter further delves into the classification of emotions, proposing a model where anger is embedded in secondary and tertiary emotions, rather than being a broad category of subcategories. The author argues that understanding complex emotions, such as resentment, requires recognizing their emergence from combinations of primary and secondary emotions. The study concludes by emphasizing the importance of classifying emotions for better understanding social interactions and the sociology of emotions.The chapter explores the roots and dynamics of anger, a fundamental emotion that is deeply rooted in human evolutionary history.
