Abstract

My dissertation defends the importance of epistemic norms on what I call ‘inquiring further.’ Inquiring further is a familiar practice we engage in when we redeliberate, gather more evidence, or double-check our beliefs. Nonetheless, many philosophers have argued that norms governing further inquiry are at most practical or moral norms. Against this, I argue that norms on inquiring further are central to our understanding of responsible epistemic agency. I do this by appealing to both the roles of epistemic evaluations and our practices of holding agents epistemically accountable. My dissertation thereby expands and deepens our understanding of epistemic evaluations and normativity. Each chapter of my dissertation focuses on a different practice of inquiring further. The first, “A Puzzle About Fickleness,” motivates a puzzle about changes of mind resulting from redeliberation. The puzzle is to explain the asymmetry between one-off changes of mind, which often seem permissible, and multiple changes of mind—or fickleness—which often seem problematic. After motivating an epistemic solution to the puzzle, I propose and defend the Ratifiable Reasoning Account. On this solution, as agents redeliberate, they gain two types of evidence. First, they gain inductive evidence that they will not stably settle their belief. Second, this inductive evidence affords higher-order evidence that they are unreliable at assessing the matter at hand. The fact that fickle agents gain this higher-order evidence explains why fickleness can be epistemically—not just practically—irrational. The second chapter turns to our practices of evidence-gathering. In “Epistemic Norms on Evidence-Gathering,” I and my co-author, Carolina Flores, argue that there are epistemic norms on evidence-gathering. Though this view is intuitive, it has found surprisingly little defense. Rather, many philosophers have argued that norms on evidence-gathering can only be practical or moral. On a prominent evidentialist version of this position, epistemic norms only apply to responding to the evidence one already has; justified or rational beliefs are those based on appropriate responses to that evidence. Here we challenge the orthodoxy. First, we argue that there is no significant normative difference between responding to evidence you have and gathering more evidence. Second, we argue that our practices of epistemically criticizing agents for their poor evidence-gathering indicate the existence of epistemic norms on evidence-gathering. Finally, we show that our thesis has important implications for recent debates about the relationship between epistemic norms and inquiry. The third chapter, “Why Double-Check?”, explores the relationship between double-checking and knowledge. I argue that agents can simultaneously know that p and rationally double-check that p. Call this view the Synchronic Compatibility Thesis. Although intuitive, this thesis faces two challenges. First, some have argued that agents who double-check ought to suspend judgment while inquiring; they thus lose knowledge while double-checking, if only temporarily. Second, some have argued that if it is rational to double-check that p, then one does not know that p. This claim is motivated by strong conceptions of belief or pragmatic encroachment. I argue that these competing views fail to accommodate the many reasons why agents might double-check, ranging from seeking certainty to making one’s beliefs more resilient. Moreover, the alternative views rely on overly strong assumptions about what inquiry, knowledge, or belief requires. By exploring fickleness, evidence-gathering, and double-checking—three phenomena that traditional epistemology has neglected—this dissertation enriches epistemology by making it more relevant to real-world agents.
