Acceptance, Belief, and Partiality: Topics in Doxastic Control, the Ethics of Belief, and the Moral Psychology of Relationships

This dissertation contains a philosophical project and a psychological project. Together, they explore two central themes, and the relation between them: (1) doxastic control and the ethics of belief, and (2) the moral and epistemic import of close personal relationships. The philosophical project (Chapters 1 and 2) concerns a central puzzle in the ethics of belief: how can we make sense of apparent obligations to believe for moral or practical reasons, if we lack the ability to form beliefs in response to such reasons? I draw on empirical work in emotion regulation to make progress on this problem of doxastic control. The psychological project (Chapters 3 and 4) concerns the role of relational closeness in moral judgment: though empirical moral psychology has traditionally focused on judgments about anonymous strangers, I contribute to a growing body of work showing how personal relationships can dramatically affect moral reasoning. Chapter 1, “Acceptance and the Ethics of Belief,” develops an empirically plausible and mechanistically detailed account of acceptance, the attitude classically characterized as “taking a proposition as a premise in practical reasoning and action.” I argue that acceptance centrally involves preventing a belief from playing its characteristic role in guiding cognition, reasoning, and action, that this centrally involves a “cognitive gating” operation, and that this view gains empirically plausibility by its analogy to well-studied strategies in emotion regulation. Ultimately, I defend acceptance as doxastic response modulation. I propose that this account holds promise for addressing puzzles in the ethics of belief—a domain plagued by the central theoretical challenge of our inability to believe for non-evidential reasons. Chapter 2, “Reframing Epistemic Partiality,” applies my account of acceptance to a specific debate in the ethics of belief: the epistemic partiality debate, which asks whether we sometimes ought to believe against the evidence regarding our friends. Though compelling, the partialist view has been plagued by serious objections. I argue that the debate has been focused on the wrong doxastic attitude: recasting our duties of friendship as duties of acceptance, rather than belief, satisfies the partialist intuitions, without falling prey to the varied objections against the view. Chapter 3, “What We Would (but Shouldn’t) Do for Those We Love” builds on prior work demonstrating that people say they are far more likely to report a distant other, compared to a close other, who commits a serious moral transgression. Across four studies, I demonstrate that people not only say they would protect close others more than distant others, but also that they say it is morally right to show such partiality towards close others. Furthermore, I show that people say that they would protect close others more than they think they should—suggesting that moral decisions involving those closest to us may be a context in which people are particularly likely to fail to do what they think is right. Chapter 4, “How Relationship Affects Adolescents’ Decisions to Report Moral Transgressions,” investigates how 6th-9th graders respond to the transgressions of close versus distant others. Given the social importance of peer relationships in adolescence, the role of relationship is central to understanding this stage of moral development. I show that adolescents—like adults—are more likely to report distant others who transgress than close others, and more likely to report serious moral transgressions than minor ones.PhDPhilosophy & Psychology PhDUniversity of Michigan, Horace H.
