• Rational Polarization
    Philosophical Review 132 (3): 355-458. 2023.
    Predictable polarization is everywhere: we can often predict how people’s opinions, including our own, will shift over time. Extant theories either neglect the fact that we can predict our own polarization, or explain it through irrational mechanisms. They needn’t. Empirical studies suggest that polarization is predictable when evidence is ambiguous, that is, when the rational response is not obvious. I show how Bayesians should model such ambiguity and then prove that—assuming rational updates …Read more
  • On the pure logic of justified belief
    Daniela Schuster and Leon Horsten
    Synthese 200 (5): 1-21. 2022.
    Justified belief is a core concept in epistemology and there has been an increasing interest in its logic over the last years. While many logical investigations consider justified belief as an operator, in this paper, we propose a logic for justified belief in which the relevant notion is treated as a predicate instead. Although this gives rise to the possibility of liar-like paradoxes, a predicate treatment allows for a rich and highly expressive framework, which lives up to the universal ambit…Read more
  • Contemporary public discourse is saturated with speech that vilifies and incites hatred or violence against vulnerable groups. The term “hate speech” has emerged in legal circles and in ordinary language to refer to these communicative acts. But legal theorists and philosophers disagree over how to define this term. This paper makes the case for, and subsequently develops, the first corpus-based analysis of the ordinary meaning of “hate speech.” We begin by demonstrating that key interpretive an…Read more

  • Sceptical Scenarios Are Not Error-Possibilities
    Erkenntnis 78 (1): 59-72. 2013.
    On a common view of scenario-based sceptical arguments sceptical scenarios are error-possibilities, i.e. their point is to introduce the possibility of having only false beliefs. However, global error is impossible for purely logical/conceptual reasons: Even if one’s beliefs are consistent, the negations of one’s beliefs need not be consistent as well. My paper deals with the question of what the consequences of this result are. Two attempts at repairing scenario-based sceptical arguments within…Read more
  • Subjective Versus Objective Moral Wrongness
    Cambridge University Press. 2021.
    There is presently a debate between Subjectivists and Objectivists about moral wrongness. Subjectivism is the view that the moral status of our actions, whether they are morally wrong or not, is grounded in our subjective circumstances – either our beliefs about, or our evidence concerning, the world around us. Objectivism, on the other hand, is the view that the moral status of our actions is grounded in our objective circumstances – all those facts other than those which comprise our subjectiv…Read more
  • Many population axiologies avoid the Repugnant Conclusion by endorsing Superiority: some number of great lives is better than any number of mediocre lives. But as Nebel shows, RC follows from the Intrapersonal Repugnant Conclusion: a guaranteed mediocre life is better than a sufficiently small probability of a great life. This result is concerning because IRC is plausible. Recently, Kosonen has argued that IRC can be true while RC is false if small probabilities are discounted to zero. This arti…Read more
  • On Travis cases
    Linguistics and Philosophy 35 (1): 3-19. 2012.
    Charles Travis has been forcefully arguing that meaning does not determine truth-conditions for more than two decades now. To this end, he has devised ingenious examples whereby different utterances of the same prima facie non-ambiguous and non-indexical expression type have different truth-conditions depending on the occasion on which they are delivered. However, Travis does not argue that meaning varies with circumstances; only that truth-conditions do. He assumes that meaning is a stable feat…Read more
  • Desire
    Kyle Blumberg and John Hawthorne
    Philosophers' Imprint 22 (n/a). 2022.
    In this paper, we present two puzzles involving desire reports concerning series of events. What does a person want to happen in the first event – is it the event with the highest expected return, or the event that is the initial part of the best series? We show that existing approaches fail to resolve the puzzles around this question and develop a novel account of our own. Our semantics is built around three ideas. First, we propose that desire ascriptions are evaluated relative to a contextual…Read more
  • #MeToo & the role of Outright Belief
    Ethical Theory and Moral Practice 25 (2): 181-197. 2022.
    In this paper, I provide an account of the wrong that is done to women when everyday people fail to believe allegations of sexual assault made by women. I argue that an everyday person wrongs both the accuser and women causally distant from the accuser when they fail to believe the accuser’s allegation. First, I argue that there are responses that we, as everyday members of society, owe to victims of sexual assault. A condition enabling everyday people to respond in the way owed to victims is th…Read more
  • Is Epistemic Normativity Value-Based?
    Charles Côté-Bouchard
    Dialogue 56 (3): 407-430. 2017.
    What is the source of epistemic normativity? In virtue of what do epistemic norms have categorical normative authority? According to epistemic teleologism, epistemic normativity comes from value. Epistemic norms have categorical authority because conforming to them is necessarily good in some relevant sense. In this article, I argue that epistemic teleologism should be rejected. The problem, I argue, is that there is no relevant sense in which it is always good to believe in accordance with epis…Read more
  • Reasons matter greatly to us in both ordinary and theoretical contexts, being connected to two fundamental normative concerns: figuring out what we should do and what attitudes to have, and understanding the duties and responsibilities that apply to us. This book introduces and critiques most of the contemporary theories of normative reasons considerations that speak in favor of an action, belief, or emotion - to explore how they work. Artūrs Logins develops and defends a new theory: the Eroteti…Read more
  • Ensemble prospectism
    Kim Kaivanto
    Theory and Decision 83 (4): 535-546. 2017.
    Incomplete preferences displaying ‘mildly sweetened’ structure are common, yet theoretically problematic. This paper examines the properties of the rankings induced by the set of all coherent completions of the mildly sweetened partial preference structure. Building on these properties, I propose an ensemble-based refinement of Hare’s prospectism criterion for rational choice when preferences are incomplete. Importantly, this ensemble-based refinement is immune to Peterson’s weak money pump argu…Read more
  • The Many, the Few, and the Nature of Value
    Ergo: An Open Access Journal of Philosophy 9 (4): 70-87. 2022.
    John Taurek argues that, in a choice between saving the many or the few, the numbers should not count. Some object that this view clashes with the transitivity of ‘better than’; others insist the clash can be avoided. I defend a middle ground: Taurek cannot have transitivity, but that doesn’t doom his view, given a suitable conception of value. I then formalize and explore two conceptions: one context-sensitive, one multidimensional.
  • Why Mental Disorders are not Like Software Bugs
    Philosophy of Science 89 (4): 661-682. 2022.
    According to the Argument for Autonomous Mental Disorder, mental disorder can occur in the absence of brain disorder, just as software problems can occur in the absence of hardware problems in a computer. This article argues that the AAMD is unsound. I begin by introducing the “natural dysfunction analysis” of disorder, before outlining the AAMD. I then analyze the necessary conditions for realizer autonomous dysfunction. Building on this, I show that software functions disassociate from hardwar…Read more
  • Epistemic Blame and the New Evil Demon Problem
    Philosophical Studies 179 (8): 2475-2505. 2022.
    The New Evil Demon Problem presents a serious challenge to externalist theories of epistemic justification. In recent years, externalists have developed a number of strategies for responding to the problem. A popular line of response involves distinguishing between a belief’s being epistemically justified and a subject’s being epistemically blameless for holding it. The apparently problematic intuitions the New Evil Demon Problem elicits, proponents of this response claim, track the fact that th…Read more
  • Losing grip on the third realm: against naive realism for intuitions
    Bar Luzon and Preston J. Werner
    Analysis 82 (3): 435-444. 2022.
    Naive realism in philosophy of perception is the view that (successful) perception involves a direct relation between perceiving subjects and the world. The naive realist says that your perception of a cat on the mat is a worldly relation which is partially constituted by the cat and the mat; a spatio-temporal chunk of the world is presenting itself to you. Recently, Elijah Chudnoff and John Bengson have independently developed an extension of this view to intellectual experiences, or intuitions…Read more
  • Be Not Afraid: The Virtue of Fearlessness
    Philosophers' Imprint 21 (23). 2021.
    Most contemporary virtue theorists hold that fear of genuine dangers is appropriate, and that what matters is one’s ability to surmount it when necessary. To overcome fear for the sake of the good is an act of courage, while succumbing to it is the manifestation of cowardice. This orthodox view comprises a significant oversight. While it is true that overcoming one’s fear in a moment of crisis is a mark of excellence, courage is not the highest ideal toward which we ought to strive. Virtue theor…Read more
  • People with Common Priors Can Agree to Disagree
    Review of Symbolic Logic 8 (1): 11-45. 2015.
    Robert Aumann presents his Agreement Theorem as the key conditional: “if two people have the same priors and their posteriors for an event A are common knowledge, then these posteriors are equal” (Aumann, 1976, p. 1236). This paper focuses on four assumptions which are used in Aumann’s proof but are not explicit in the key conditional: (1) that agents commonly know, of some prior μ, that it is the common prior; (2) that agents commonly know that each of them updates on the prior by conditionali…Read more
  • Against normativism about mental attitudes
    Analytic Philosophy 62 (3): 295-311. 2021.
    Analytic Philosophy, Volume 62, Issue 3, Page 295-311, September 2021.
  • This paper argues that we should reject G. E. Moore’s anti-skeptical argument as it is presented in “Proof of an External World.” However, the reason I offer is different from traditional objections. A proper understanding of Moore’s “proof” requires paying attention to an important distinction between two forms of skepticism. I call these Ontological Skepticism and Epistemic Skepticism. The former is skepticism about the ontological status of fundamental reality, while the latter is skepticism …Read more
  • The Activity of Reasoning: How Reasoning Can Constitute Epistemic Agency
    Pacific Philosophical Quarterly 102 (3): 413-428. 2021.
    We naturally see ourselves as capable of being active with respect to the matter of what we believe – as capable of epistemic agency. A natural view is that we can exercise such agency by engaging in reasoning. Sceptics contend that such a view cannot be maintained in light of the fact that reasoning involves judgements, which are not decided upon or the products of prior intentions. In response, I argue that reasoning in fact can amount to epistemic agency in virtue of its being aim-directed in…Read more
  • Fragile Knowledge
    Mind 131 (522): 487-515. 2022.
    This paper explores the principle that knowledge is fragile, in that whenever S knows that S doesn’t know that S knows that p, S thereby fails to know p. Fragility is motivated by the infelicity of dubious assertions, utterances which assert p while acknowledging higher-order ignorance whether p. Fragility is interestingly weaker than KK, the principle that if S knows p, then S knows that S knows p. Existing theories of knowledge which deny KK by accepting a Margin for Error principle can be con…Read more
  • Proceed with Caution
    Canadian Journal of Philosophy (1): 6-25. 2021.
    It is becoming more common that the decision-makers in private and public institutions are predictive algorithmic systems, not humans. This article argues that relying on algorithmic systems is procedurally unjust in contexts involving background conditions of structural injustice. Under such nonideal conditions, algorithmic systems, if left to their own devices, cannot meet a necessary condition of procedural justice, because they fail to provide a sufficiently nuanced model of which cases coun…Read more
  • Belief in Psyontology
    Philosophers' Imprint 20 (11). 2020.
    Neither full belief nor partial belief is more fundamental, ontologically speaking. A survey of some relevant cognitive psychology supports a dualist ontology instead. Beliefs come in two kinds, categorical and graded, neither more fundamental than the other. In particular, the graded kind is no more fundamental. When we discuss belief in on/off terms, we are not speaking coarsely or informally about states that are ultimately credal.
  • How does being a woman affect one’s epistemic life? What about being Black? Or queer? Standpoint theorists argue that such social positions can give rise to otherwise unavailable epistemic privilege. “Epistemic privilege” is a murky concept, however. Critics of standpoint theory argue that the view is offered without a clear explanation of how standpoints confer their benefits, what those benefits are, or why social positions are particularly apt to produce them. For this reason, many regard sta…Read more

    Cambridge University Press. 2021.
    This Element provides an accessible introduction to the contemporary philosophy of causation. It introduces the reader to central concepts and distinctions and to key tools drawn upon in the contemporary debate. The aim is to fuel the reader's interest in causation, and to equip them with the resources to contribute to the debate themselves. The discussion is historically informed and outward-looking. 'Historically informed' in that concise accounts of key historical contributions to the underst…Read more
  • Hope and Despair at the Kantian Chicken Factory: Moral Arguments about Making a Difference
    In John J. Callanan & Lucy Allais (eds.), Kant and Animals, Oxford University Press. pp. 213-238. 2020.
  • Epistemic Dilemmas Defended
    In Epistemic Dilemmas, Oxford University Press. 2021.
    Daniel Greco (forthcoming) argues that there cannot be epistemic dilemmas. I argue that he is wrong. I then look in detail at a would-be epistemic dilemma and argue that no non-dilemmic approach to it can be made to work. Along the way, there is discussion of octopuses, lobsters, and other ‘inscrutable cognizers’; the relationship between evaluative and prescriptive norms; a failed attempt to steal a Brueghel; epistemic and moral blame and residue; an unbearable guy who thinks he’s God’s gift to…Read more
  • Not So Phenomenal!
    Philosophical Review 130 (1): 1-43. 2021.
    The main aims in this article are to discuss and criticize the core thesis of a position that has become known as phenomenal conservatism. According to this thesis, its seeming to one that p provides enough justification for a belief in p to be prima facie justified. This thesis captures the special kind of epistemic import that seemings are claimed to have. To get clearer on this thesis, the article embeds it, first, in a probabilistic framework in which updating on new evidence happens by Baye…Read more
