This Element explains Nietzsche's ethics in his late works, from 1886 onwards. The first three sections explain the basics of his ethical theory – its context and presuppositions, its scope and its central tension. The next three sections explore Nietzsche's goals in writing a history of Christian morality (On the Genealogy of Morality), the content of that history, and whether he achieves his goals. The last two sections take a broader look, respectively, at Nietzsche's wider philosophy in light of his ethics and at the prospects for a Nietzschean ethics after Nietzsche.
