What Are Prima Facie Duties?

Abstract

This chapter focuses on Ross’s most important conceptual innovation: the idea of prima facie duty. Four main claims are defended: first, contra some of his harsher critics, that though much of what Ross says in introducing and explaining the concept of prima facie duty is problematic or misleading, he nonetheless has a clear and coherent theoretical picture; second, contra Hurka, that Ross lacks the contemporary concept of a normative reason, but that his views should be reframed in ways that do employ that concept; third, that Ross is not and should not be a scalar deontologist; and fourth that he was wrong in the Foundations to follow Prichard in favoring subjective over objective rightness.
