In this paper, I introduce a new species of elusive reason–reasons that it is impossible for an agent to act, or be motivated to act, for–and I show how this kind of elusive reason undermines a plausible claim about normative reasons, the Motivational Constraint. To defend the existence of this new kind of elusive reason, I respond to the objection that our intuitions are tracking another normative or evaluative phenomenon, such as reasons to have certain affective responses or reasons for (...) others to act. In addition, because accepting the new kind of elusive reason requires affirming the claim that S acts for a reason p only if S regards p as a reason to A, I develop an account of what it is for S to regard p as a reason to A. Finally, as part of arguing for the former claim, I argue that the idea of being moved to A for a reason p entails the idea of being moved to A in light of p, which itself entails the idea of regarding p as a reason.

A minimal constraint on normative reasons seems to be that if some fact is a reason for an agent to φ (act, believe, or feel), the agent could come to know that fact. This constraint is threatened by a well-known type of counterexamples. Self-effacing reasons are facts that intuitively constitute reasons for an agent to φ, but that if they were to become known, they would cease to be reasons for that agent. The challenge posed by self-effacing reasons bears important (...) structural similarities with a range of epistemic paradoxes, most notably the Knowability Paradox. In this article, we investigate the similarities and differences between the two arguments. Moreover, we assess whether some of the approaches to the Knowability Paradox could help solve the challenge posed by self-effacing reasons. We argue that at least two popular approaches to the paradox can be turned into promising strategies for addressing the self-effacing reasons problem. (shrink)
