Cette introduction à une collection d'articles sur la normativité propose d'adopter les divisions trouvées habituellement en éthique pour aborder la normativité. Ainsi, il semble utile de diviser les questions en cinq groupes: l'ontologie normative, la sémantique normative, l'épistémologie normative, la psychologie normative, et finalement, les questions normatives substantielles.

A significant portion of recent literature on Nietzsche is devoted to his metaethical views, both critical and positive. This article explores one aspect of his positive metaethics. The specific thesis defended is that Nietzsche is, or is plausibly cast as, a reasons internalist. This, very roughly, is the view that what an agent has normative reason to do depends on that agent's motivational repertoire. Section I sketches some of the metaethical terrain most relevant to Nietzsche's organising ethical project, his “revaluation (...) of all values”, and lays out three “design-requirements” that an adequate account of Nietzsche's metaethical views must satisfy. Section II introduces the basic internalist position. Sections III–IV provide textual support for the internalist reading of Nietzsche, with Section V showing how it meets each of the design-requirements. Section VI concludes by showing how the internalist apparatus also illuminates Nietzsche's views about the process of revaluing values. (shrink)

Some versions of moral naturalism are faulted for implausibly denying that moral obligations and prescriptions entail categorical reasons for action. Categorical reasons for action are normative reasons that exist and apply to agents independently of whatever desires they have. I argue that several defenses of moral naturalism against this charge are unsuccessful. To be a tenable meta-ethical theory, moral naturalism must accommodate the proposition that, necessarily, if anyone morally ought to do something, then s/he has a categorical reason to do (...) it. Versions of moral naturalism that deny this claim would, if widely believed, disable some crucial practical uses of moral concepts. In particular, if the existence of normative reasons for action is taken to be dependent on agents’ desires, it would breed profound skepticism about the legitimacy of evaluating others’ actions from a moral point of view. Also, it would raise doubts about whether people ought to correct their own behavior in light of moral considerations. Following Richard Joyce, I take these consequences to indicate that the concept of a categorical reason is a “non-negotiable” part of moral concepts. (shrink)
