This chapter draws on the foundation of the moral attitude and objective attitude cognitions that are held to modulate between anger and rage. In order to substantiate this theory, it begins with an analysis of prevalent theories of emotional genesis, before moving onto insights on aggression and violence from the neurosciences. Following the Appraisal Theory on Emotions, the chapter introduces the moral foundation of negative emotions, which stresses that negative emotions parallel negative moral judgement. It briefly comments on how emotions have entered the field of International Relations. Finally, the chapter uses Franz Fanon's concept of emancipatory violence as a prototypical example of an objective attitude rage that is primarily defined by a reactiveness toward a preceding mistreatment that forces the subject to view the lack of moral restraint towards the victim as necessary and virtuous.
