This chapter offers an analysis of the authoritatively normative concept PRACTICAL OUGHT that appeals to the constitutive norms for the activity of non-arbitrary selection. It argues that this analysis permits an attractive and substantive explanation of what the distinctive normative authority of this concept amounts to, while also explaining why a clear statement of what such authority amounts to has been so elusive in the recent literature. The account given is contrasted with more familiar constitutivist theories, and briefly shows how it answers “schmagency”-style objections to constitutivist explanations of normativity. Finally, the chapter explains how the account offered here can help realists, error theorist, and fictionalists address central challenges to their views.
