Abstract

According to Joseph Raz, the fact of making a valid promise creates “promissory reasons”: it constitutes for the promisor a reason for performing her promise and a reason for not acting for at least some of the reasons that recommend something different than performing. In his latest work on promising, Raz provides a novel account of the grounds of promissory reasons—an account which is different in important respects to the one he defended decades ago. In this paper, I argue that, as his previous one, his latest account of the grounds of promissory reasons faces significant difficulties.
