Anger, far from being only a personal emotion, often signals a breakdown in existing societal structures like the justice system. This does not mean we should uncritically submit to our angry impulses, but it does mean that anger can reveal larger issues in the world worthy of attention. If we banish anger from the socio-political landscape, we risk losing its insights. To defend that claim, I turn to a range of sources from ancient China and Greece—philosophy, poetry, drama, and political theory—that depict and analyze anger in a variety of situations and people. My basic claim is not that anger is simply “good” or “bad” but rather that it helps reveal and clarify our values, often pointing us towards real situations deserving of our ethical scrutiny. I situate the project amidst ongoing debates in analytic philosophy of emotions and feminist philosophy, joining the conceptual precision and clarity of the former with the latter’s attention to lived experience. Such cross-cultural, multidisciplinary conceptual analysis of anger parochializes Aristotelian understandings of anger by introducing different types and functions of anger. What role does anger play, for example, in a minister rebuking the king in an ancient Chinese court? How do Greek sources depict female anger differently than male anger, and why? By using ancient and comparative sources, I show how deeply anger is shaped by particular cultural and social structures, whilst remaining recognizably anger.
