The article proposes a novel approach to mental agency that is inspired by Victoria McGeer’s work on self-regulation. The basic idea is that certain mental acts leave further work to be done for an agent to be considered an authoritative self-ascriber of corresponding dispositional mental states. First, we discuss Richard Moran’s account of avowals, which grounds first-person authority in deliberative, self-directed agency. Although this view is promising, we argue that it ultimately fails to confront the empirical gap between occurrent judgments (...) and dispositional beliefs. Second, we show how Victoria McGeer's account of self-regulation allows us to bridge this gap by emphasizing that avowals are only reliable and authoritative insofar as we take certain steps to live up to the commitments inherent in our self-ascriptions. Third, we address the question whether and to what extent self-regulation can be seen as a form of mental agency. Unlike the ‘pure’ deliberative form of mental agency advocated by Moran, which is direct, conscious and intra-personal, we follow McGeer and argue for a notion of mental agency as an indirect, unconscious and inter-personal process of self-regulation.
