Abstract

_Ressentiment_—the hateful desire for revenge—plays a pivotal role in Nietzsche’s _On the Genealogy of Morals_. _Ressentiment _explains the formation of bad conscience, guilt, asceticism, and, most importantly, it motivates the "slave revolt" that gives rise to Western morality’s values. _Ressentiment_, however, has not enjoyed a thorough treatment in the secondary literature. This book brings it sharply into focus and provides the first detailed examination of Nietzsche’s psychology of _ressentiment_. Unlike other books on the _Genealogy_, it uses _ressentiment_ as a key to the _Genealogy_ and focuses on the intriguing relationship between _ressentiment_ and justice. It shows how _ressentiment_, despite its blindness to justice, gives rise to moral justice—the central target of Nietzsche’s critique. This critique notwithstanding, the _Genealogy_ shows Nietzsche’s enduring commitment to the virtue of _non-moral_ justice: a commitment that grounds his provocative view that moral justice spells the ‘end of justice’. The result provides a novel view of Nietzsche's moral psychology in the _Genealogy_, his critique of morality, and his views on justice.
