My primary research revolves around a few themes – rationality, language, and virtue – and their importance for accounts of human excellence and achievement. These central concerns manifest themselves in particular interests in epistemology, ethics, social and political philosophy, philosophy of language, and metaphysics.

- Knowledge implies the presence of a positive relation between a person and a fact. Factual ignorance, on the other hand, implies the absence of some positive relation between a person and a fact. The two most influential views of ignorance hold that what is lacking in cases of factual ignorance is knowledge or true belief, but these accounts fail to explain a number of basic facts about ignorance. In their place, we propose a novel and systematic defense of the view that factual ignorance is the absence of awareness, an account that both comes apart from the dominant views and overcomes their deficiencies. Given the important role that ignorance plays in moral and legal theory and our understanding of various epistemic injustices, a precise and theoretically unproblematic account of the nature of ignorance is important not only for normative epistemology, but also for law, ethics, and applied epistemology.
Many political philosophers have held that democracy has epistemic benefits. Most commonly, this case is made by arguing that democracies are better able to track the truth than other political arrangements. Truth, however, is not the only epistemic good that is politically valuable. A number of other epistemic goods – goods including evidence, intellectual virtue, epistemic justice, and empathetic understanding – can also have political value, and in ways that go beyond the value of truth. In this paper, I will survey those who have argued that democracy can be valuable because of these other epistemic benefits, considering (1) the ways in which these epistemic goods can be of political value and (2) the challenges that democracies face in producing them.

In order to serve their citizens well, democracies must secure a number of epistemic goods. Take the truth, for example. If a democratic government wants to help its impoverished citizens improve their financial position, then elected officials will need to know what policies truly help those living in poverty. Because truth has such an important role in political decision-making, many defenders of democracy have highlighted the ways in which democratic procedures can lead to the truth. But there are also a number of other epistemic goods – goods like evidence, intellectual virtue, epistemic justice, and empathetic understanding – that democracies can benefit from producing as well. In this teaching and learning guide, I chart a course through the literature that considers the importance of truth, along with these other political goods, for the healthy functioning of democracies.

- Inspired by the practice of dialogue in ancient philosophical schools, the Philosophy as a Way of Life (PWOL) Project at the University of Notre Dame has sought to put dialogue back at the center of philosophical pedagogy. Impromptu philosophical dialogue, however, can be challenging for students who are new to philosophy. Anticipating this challenge, the Project has created a series of manuals to help instructors conduct dialogue groups with novice philosophy students. Using these guidelines, we incorporated PWOL-style dialogue groups into our Spring 2021 course, "The Philosophy of Race, Class, and Gender", with the hope that, through having conversations about these challenging topics, our students would both be able to practice having philosophical dialogues as well as form their views on race and gender in light of contributions from their diverse peers. This article examines several strategies for how instructors can seek to incorporate similar dialogues into their own introductory classrooms.
- Modal metaphysics consumed much of the philosophical discussion at the turn of the century, yielding a number of epistemological insights. Modal analyses were applied within epistemology, yielding sensitivity and safety theories of knowledge as well as counterfactual accounts of the basing relation. The contemporary conversation has now turned to a new metaphysical notion - grounding - opening the way to a fresh wave of insights by bringing grounding into epistemology. In this paper, I attempt one such application, making sense of the epistemic regress problem in terms of grounding. I argue that the relation that generates the epistemic regress is a grounding relation, showing that grounding can make sense of proposals by epistemic foundationalists and charting the course for similar applications to epistemic coherentism and epistemic infinitism. If it is right that grounding is involved in the epistemic regress, this points the way forward both for epistemologists and metaphysicians, revealing the prospects of solutions to the epistemic regress problem while providing grounding advocates with yet another example of grounding with which to theorize.
If political decision-making aims at getting a particular result, like identifying just laws or policies that truly promote the common good, then political institutions can also be evaluated in terms of how often they achieve these results. Epistemic defenses of democracy argue that democracies have the upper hand when it comes to truth, identifying the laws and policies that are truly just or conducive to the common good. A number of epistemic democrats claim that democracies have this beneficial connection to truth because of the type of deliberative environment created by democratic political institutions. Democratic political cultures make it easier to exchange and give reasons, ultimately improving the justification that citizens have for their political beliefs. With this improved justification comes a better chance at truth, or so the story goes. In this paper, I show that attempts to forge a connection between justification and truth in epistemology have encountered numerous difficulties, making the case that this causes trouble for deliberative epistemic defenses of democracy as well. If there is no well-defined connection between truth and justification, then increasing the justification that citizens have for their beliefs may not also increase the likelihood that those beliefs are true, revealing a serious flaw in charting a connection between political justification and political truth.

- Against the maximizing conception of practical rationality, Michael Slote has argued that rationality does not always require choosing what is most rational. Instead, it can sometimes be rational to do something that is less than fully rational. In this paper, I will argue that maximizers have a ready response to Slote’s position. Roy Sorensen has argued that ‘rational’ is an absolute term, suggesting that it is not possible to be rational without being completely rational. Sorensen’s view is confirmed by the fact that, by the lights of contemporary linguistics, ‘rational’ is an absolute gradable adjective. Because ‘rational’ is an absolute gradable adjective, being rational requires being at the top of the scale of rationality, making anyone who is not fully rational positively irrational. Contra Slote, the only way to be rational enough is to be maximally rational.

8. "Checking and the Argument from Inquiry," Acta Analytica (2023) 38: 69-78 (Draft), Invited Commentary on Guido Melchior's Knowing and Checking
- In n his recent book, Knowing and Checking, Guido Melchior argues that, when we attempt to check whether p, we tend to think that we do not know p. Melchior then uses this assumption to explain a number of puzzles about knowledge. One outstanding question for Melchior’s account, however, is why this tendency exists. After all, Melchior himself argues that checking is not necessary for knowing, so why would we think that we fail to know that p when we are in the midst of checking that p? I will explore one such suggestion for why this occurs, arguing that the connection between checking and inquiry can shed light on the impact that checking has on knowing.

Starting with the slogan that understanding is a “knowledge of causes,” Stephen Grimm and John Greco have argued that understanding comes from a knowledge of dependence relations. Grounding is the trendiest dependence relation on the market, and if Grimm and Greco are correct, then instances of grounding should also give rise to understanding. In this paper, I will show that this prediction is correct – grounding does indeed generate understanding in just the way that Grimm and Greco anticipate. However, grounding examples of understanding also show that Grimm and Greco are not telling the full story when it comes to understanding. Understanding can only be generated by a particular subset of dependence relations — those dependence relations that are also explanatory. Grimm and Greco should thus appeal to a privileged class of dependence relations, relations like grounding that can give rise to explanation as well.
- It is no secret that we, as a society, struggle to have productive conversations about race and gender. Discussions about these issues are beset with obstacles, from the inherent power dynamics between conversation partners to the fear that participants feel about saying something harmful. One practice that can help address these difficulties is intergroup dialogue - sustained, small group discussions with participants from a variety of social identities. In this paper, we detail how we incorporated intergroup dialogue into a 120 student ``Philosophy of Race, Class, and Gender'' course, providing a blueprint for anyone who wants to help their students develop the ability to take part in fruitful conversations surrounding these challenging topics. We provide strategies for how to design intergroup dialogues to avoid many of the common pitfalls of such conversations, strategies that ultimately helped our students become more likely to initiate and participate in worthwhile discussions on race and gender. We expect our experiences to be especially helpful for instructors of large courses, where making time for small group dialogue is quite challenging, but many of the practices we used can also be adapted for smaller scale courses as well.

A number of authors have defended permissivism by appealing to rational supererogation, the thought that some doxastic states might be rationally permissible even though there are other, more rational beliefs available. If this is correct, then there are situations that allow for multiple rational doxastic responses, even if some of those responses are rationally suboptimal. In this paper, I will argue that this is the wrong approach to defending permissivism – there are no doxastic states that are rationally supererogatory. By the lights of contemporary linguistics, ‘rational’ is an absolute gradable adjective, and as such, can only be applied to things that satisfy the top of the scale of rationality. For this reason, it is not possible to believe what is rational while also failing to believe what is rationally optimal.
Philosophical orthodoxy holds that Thomas Reid is an externalist concerning epistemic justification, characterizing Reid as holding the key to an externalist response to internalism. These externalist accounts of Reid, however, have neglected his work on prejudice, a heretofore unexamined aspect of his epistemology. Reid's work on prejudice reveals that he is far from an externalist. Despite the views Reid may have inspired, he exemplifies internalism in opting for an accessibility account of justification. For Reid, there are two normative statuses that a belief might satisfy, being blameless and having a just ground. Through reflection, a rational agent is capable of satisfying both of these statuses, making Reid an accessibility internalist about epistemic justification.
- Traditional epistemologists assumed that the most important doxastic norms were rational requirements on belief. This orthodoxy has recently been challenged by the work of revolutionary epistemologists on the rational requirements on credences. Revolutionary epistemology takes it that such contemporary work is important precisely because traditional epistemologists are mistaken -- credal norms are more fundamental than, and determinative of, belief norms. To make sense of their innovative project, many revolutionary epistemologists have also adopted another commitment, that norms on credences are governed by a fundamental accuracy norm. Unfortunately for the revolutionary epistemologist, it has been difficult to define a measure of accuracy while maintaining that credal norms are more basic than belief norms. In this paper, I criticize one such proposal for measuring accuracy, that the accuracy of our credences should be assessed in terms of what we know, arguing that this picture ultimately cannot vindicate the revolutionary approach.
- Formal epistemologists often claim that our credences should be representable by a probability function. Complete probabilistic coherence, however, is only possible for ideal agents, raising the question of how this requirement relates to our everyday judgments concerning rationality. One possible answer is that being rational is a contextual matter, that the standards for rationality change along with the situation. Just like who counts as tall changes depending on whether we are considering toddlers or basketball players, perhaps what counts as rational shifts according to whether we are considering ideal agents or creatures more like ourselves. Even though a number of formal epistemologists have endorsed this type of solution, I will argue that there is no way to spell out this contextual account that can make sense of our everyday judgments about rationality. Those who defend probabilistic coherence requirements will need an alternative account of the relationship between real and ideal rationality.

James Joyce’s article “A Nonpragmatic Vindication of Probabilism” introduced an approach to arguing for credal norms by appealing to the epistemic value of accuracy. The central thought was that credences ought to accurately represent the world, a guiding thought that has gone on to generate an entire research paradigm on the rationality of credences. Recently, a number of epistemologists have begun to apply this same thought to full beliefs, attempting to explain and argue for norms of belief in terms of epistemic value. This paper examines these recent attempts, showing how they interact with work on the accuracy of credences. It then examines how differing judgments about epistemic value give rise to distinct rational requirements for belief, concluding by considering some of the fundamental questions and issues yet to be fully explored.

Traditional rationalist approaches to a priori epistemology have long been looked upon with suspicion for positing a faculty of rational intuition capable of knowing truths about the world apart from experience. Conceptualists have tried to fill this void with something more empirically tractable, arguing that we know a priori truths due to our understanding of concepts. All of this theorizing, however, has carried on while neglecting an entire cross section of such truths, the grounding claims that we know a priori. Taking a priori grounding into account poses a significant challenge to conceptualist accounts of a priori knowledge, as it is unclear how merely understanding conceptual connections can account for knowledge of grounding. The fact that we do know some grounding truths a priori then is a significant mark in traditional rationalism's favor, and the next frontier for those who aim to eliminate the mystery surrounding a priori knowledge.
- It is clear that beliefs can be assessed both as to their justification and their rationality. What is not as clear, however, is how the rationality and justification of belief relate to one another. Stewart Cohen has stumped for the popular proposal that rationality and justification come to the same thing, that rational beliefs just are justified beliefs, supporting his view by arguing that ‘justified belief’ and ‘rational belief’ are synonymous. In this paper, I will give reason to think that Cohen’s argument is spurious. I will show that ‘rational’ and ‘justified’ occupy two distinct semantic categories – ‘rational’ is an absolute gradable adjective and ‘justified’ is a relative gradable adjective – telling against the thought that ‘rational belief’ and ‘justified belief’ are synonymous. I will then argue that the burden of proof is on those who would equate rationality and justification, making the case that those who hold this prominent position face the difficulty of explaining how rationality and justification come to the same thing even though ‘rational’ and ‘justified’ are not synonymous.
Externalists about epistemic justification have long emphasized the connection between truth and justification, with this coupling finding explicit expression in process reliabilism. Process reliabilism, however, faces a number of severe difficulties, leading disenchanted process reliabilists to find a new theoretical home. The conceptual flag under which such epistemologists have preferred to gather is that of dispositions. Just as reliabilism is determined by the frequency of a particular outcome, making it possible to characterize justification in terms of a particular relationship to truth, dispositions are accompanied by concrete, worldly manifestations. By taking true beliefs as the result, not of certain processes but of particular dispositions, these epistemologists have attempted to respond to the numerous obstacles to reliablism. Yet all this work has proceeded without regard to the wealth of contemporary work on the metaphysics of dispositions, making the new hope premature at best, ill-founded at worst. Combining contemporary dispositional accounts of justification with extant analyses of dispositions reveals that the latter is the case. The structural differences between epistemic justification and dispositions make it clear that not only should process reliabilism be abandoned, but the subsequent appeal to dispositions along with it.

- A number of formal epistemologists have argued that perfect rationality requires probabilistic coherence, a requirement that they often claim applies only to ideal agents. However, in “Rationality as an Absolute Concept,” Roy Sorensen contends that ‘rational’ is an absolute term. Just as Peter Unger argued that being flat requires that a surface be completely free of bumps and blemishes, Sorensen claims that being rational requires being perfectly rational. However, when we combine these two views, they lead to counterintuitive results. If being rational requires being perfectly rational, and only the probabilistically coherent are perfectly rational, then this indicts all ordinary agents as irrational. In this paper, I will attempt to resolve this conflict by arguing that Sorensen is only partly correct. One important sense of ‘rational,’ the sanctioning sense of ‘rational’, is an absolute term, but another important sense of ‘rational,’ the sense in which someone can have rational capacities, is not. I will, then, show that this distinction has important consequences for theorizing about ideal rationality, developing an account of the relationship between ordinary and ideal rationality. Because the sanctioning sense of ‘rational’ is absolute, it is rationally required to adopt the most rational attitude available, but which attitude is most rational can change depending on whether we are dealing with ideal agents or people more like ourselves.

21. "Stoic Virtue: A Contemporary Interpretation," Philosophers' Imprint (2020) 20: pp. 1-20 (Open Access)
The Stoic understanding of virtue is often taken to be a non-starter. Many of the Stoic claims about virtue – that a virtuous requires moral perfection and that all who are not fully virtuous are vicious – are thought to be completely out of step with our commonsense notion of virtue, making the Stoic account more of an historical oddity than a seriously defended view. Despite many voices to the contrary, I will argue that there is a way of making sense of these Stoic claims. Recent work in linguistics has shown that there is a distinction between relative and absolute gradable adjectives, with the absolute variety only applying to perfect exemplars. I will argue that taking virtue terms to be absolute gradable adjectives – and thus that they apply only to those who are fully virtuous – is one way to make sense of the Stoic view. I will also show how interpreting virtue-theoretic adjectives as absolute gradable adjectives makes it possible to defend Stoicism against its most common objections, demonstrating how the Stoic account of virtue might once again be a player in the contemporary landscape of virtue theorizing.

How demanding is the virtuous life? Can virtue exist alongside hints of vice? Is it possible to be virtuous within a vicious society? A line of thinking running through Diogenes and the Stoics is that even a hint of corruption is inimical to virtue, that participating in a vicious society makes it impossible for a person to be virtuous. One response to this difficulty is to claim that virtue is a threshold concept, that context sets a threshold for what is considered virtuous. On this way of thinking, what counts as virtuous in one society may be more demanding than what passes for virtuous in another. This response seems plausible when considering that virtue-theoretic terms like ‘honest’ are gradable adjectives. Many gradable adjectives, like ‘long’ and ‘expensive,’ have contextual thresholds that shift depending on the situation, and so it is tenable that virtue-theoretic adjectives might function with contextual thresholds as well. A major difficulty for this response, however, is that many virtue terms are absolute gradable adjectives, a variety of gradable adjectives that do not require a contextual threshold. These absolute gradable adjectives instead draw their truth conditions from their maximal degree, suggesting that Diogenes and the Stoics were correct to think that a number of the virtues are incompatible with even a small degree of vice.

A strength of liberal political institutions is their ability to accommodate pluralism, both allowing divergent comprehensive doctrines as well as constructing the common ground necessary for diverse people to live together. A pressing question is how far such pluralism extends. Which comprehensive doctrines are simply beyond the pale and need not be accommodated by a political consensus? Rawls attempted to keep the boundaries of reasonable disagreement quite broad by infamously denying that political liberalism need make reference to the concept of truth, a claim that has been criticized by Joseph Raz, Joshua Cohen, and David Estlund. In this paper, we argue that these criticisms fail due to the fact that political liberalism can remain non-committal on the nature of truth, leaving the concept of truth in the domain of comprehensive doctrines, while still avoiding the issues raised by Raz, Cohen, and Estlund. Further substantiating this point is the fact that Rawls would, and should, include parties in the overlapping consensus whose views on truth may be incoherent. Once it is seen that political liberalism allows such incoherence to reasonable parties, it is clear that the inclusion of truth and the requirement of coherence urged by Raz, Cohen, and Estlund requires more of reasonable people than is necessary for a political consensus.
