Abstract
This article discusses what we can learn about promising and about Nietzsche’s critique of morality from his discussion of sovereign promising in the opening sections of the second essay of On the Genealogy of Morals. It argues that the philosophical focus of GM II: 1–2 is not the nature of promising in the narrow sense of making a pledge to do something for someone else, but the nature of pledging or committing oneself in general. It identifies the root difference between a moral obligation and a Nietzschean account of promissory fidelity. It argues that, in its focus on the difficult questions of what it means and how it is possible to bind oneself to a course of action, the Nietzschean account is philosophically deeper than the moral obligation account. Finally, the article considers misconceptions of revisionist readings of GM II: 1–2.
