Nietzsche on the Banishment of Supererogation by Luther and its Influence on Modern Ethical Life and Moral Theorizing

Nietzsche on the Banishment of Supererogation by Luther and its Influence on Modern Ethical Life and Moral Theorizing. Much attention has been paid to Nietzsche’s refusal of obligation-centred moral theories (such as Kantian deontology and Utilitarian consequentialism), but little or no attention to the historical roots of such conceptions. The aim of this paper is to explore the ways Nietzsche connects the Kantian version of legal moral theory to the Lutheran Reformation, taking as its leitmotif the exclusion by Luther of the so-called supererogation (the ideal of a Christian perfect life of sainthood being the most evident case) from the horizon of our ethical life (see D 88; GS 355; NL 1884, 25[271]). After establishing this historical connection, we are better positioned to understand the motivation behind his rejection of legal moral theories, particularly the Kantian version. This also allows us to shed new light on the contemporary attempts to characterize Nietzsche’s much-discussed perfectionist normative commitments.
