A systematic introspective study investigates how anger arises, unfolds, and subsides by tracing the mental conditions that precede it, the shifting content of consciousness during the episode, and the lingering after-effects. Based on daily reports from trained observers, it analyzes individual differences, habitual ideas and feelings associated with anger, behavioral reactions and methods that diminish or control anger, and the interplay of anger with other emotions. The final section considers implications for educating emotional responses and offers practical guidance for instructors concerned with shaping pupils' emotional habits.
