2 Nietzsche’s works are referred to by their standard English abbreviations. Translations are based on the English editions listed in the bibliography, sometimes with emendations. Nachlass material not included in The Will to Power is cited from Nietzsche’s Werke: Kritische Gesamtausgabe (KGW), ed. G. Colli and M. Montinari, who have also edited Nietzsche’s letters as Briefwechsel: Kritische Gesamtausgabe (KGB). Translations from these editions are my own.
