    Parity and the Permissivism Puzzle: A Defense of Epistemic Options
    Philosophy and Phenomenological Research. forthcoming.
    Moral philosophers generally affirm that there are moral options: a single person sometimes has multiple morally permissible actions at a time. But epistemologists generally deny that there are epistemic options: a single person never has multiple epistemically permissible doxastic attitudes at a time. This asymmetry is striking. Furthermore, there are intuitive cases of epistemic options. However, it’s not clear how these cases differ from cases where withholding is required, such as a coin fli…Read more

    The All or Nothing Ranking Reversal and the Unity of Morality
    In Timmons Mark (ed.), Oxford Studies in Normative Ethics vol. 14, Oxford University Press. pp. 69-92. 2025.
    Supererogatory acts are, in some sense, morally better their non-supererogatory alternatives. In this sense, what is it for one option A to be better than an alternative B? This chapter argues for three main conclusions. First, relative rankings are a type of all-in action guidance. If A is better than B, then morality recommends that you A rather than B. Such all-in guidance is useful when acts have the same deontic status. Second, Right > Wrong: permissible acts are always better than their im…Read more

    Acquaintance and Fallible Non-Inferential Justification
    In Brett Coppenger & Michael Bergmann (eds.), Intellectual Assurance: Essays on Traditional Epistemic Internalism, Oxford University Press Uk. pp. 43-60. 2016.
    Classical acquaintance theory is any version of classical foundationalism that appeals to acquaintance in order to account for non-inferential justification. Such theories are well suited to account for a kind of infallible non-inferential justification. Why is one justified in believing that one is in pain? An initially attractive (partial) answer is that one is acquainted with one’s pain. But since one can’t be acquainted with what isn’t there, acquaintance with one’s pain guarantees that one …Read more

    Perceptual Justification and Warrant by Default
    Australasian Journal of Philosophy 87 (3): 445-463. 2009.
    As I use the term, ‘entitlement’ is any warrant one has by default—i.e. without acquiring it. Some philosophers not only affirm the existence of entitlement, but also give it a crucial role in the justification of our perceptual beliefs. These philosophers affirm the Entitlement Thesis: that an essential part of what makes our perceptual beliefs justified is our entitlement to the proposition that I am not a brain-in-a-vat. Crispin Wright, Stewart Cohen and Roger White are among those who endors…Read more

    It is natural to think that many of our beliefs are rational because they are based on seemings, or on the way things seem. This is especially clear in the case of perception. Many of our mathematical, moral, and memory beliefs also appear to be based on seemings. In each of these cases, it is natural to think that our beliefs are not only based on a seeming, but also that they are rationally based on these seemings—at least assuming there is no relevant counterevidence. This piece is an introd…Read more

    Weighing Reasons
    Stanford Encyclopedia of Philosophy. 2025.
    This entry explains what the issue of weighing reasons is about and then discusses a number of theories concerning weighing reasons. The general issue concerns how reasons (or considerations or pros and cons) systematically interact to determine the normative status of some action, belief, or attitude. For example, it concerns how reasons determine whether an action is permissible, required, or what ought to be done. The general issue also concerns how reasons aggregate or themselves result f…Read more

    Dogmatic Withholding: Confessions of a Serial Offender
    In Verena Wagner & Zinke Alexandra (eds.), Suspension in epistemology and beyond, Routledge. 2025.
    This chapter provides an account of what dogmatism is, why the term matters, and how it applies to withholding judgment. Roughly, a person is dogmatic about P when a certain problematic personal investment—a superiority complex, broadly construed—biases their judgment concerning whether P. The term dogmatism and its cognates matter because of their social function. To accuse you of dogmatism is to signal how you are to be treated: your judgment or behavior needs to be “brought down to earth,”…Read more

    The weight of reasons: a framework for ethics
    Oxford University Press. 2024.
    The book develops, defends, and applies a "Dual Scale" model of weighing reasons to resolve various issues in ethics. It tells you everything you ever wanted to know about weighing reasons and probably a lot of stuff you didn't want to know too. It addresses, among other things, what the general issue of weighing reasons is; what it is to weigh reasons correctly; whether reasons have more than one weight value (e.g., justifying, requiring, and/or commending weight); whether weight values are con…Read more

    It may seem that epistemic and practical rationality weigh reasons differently, because ties in practical rationality tend to generate permissions and ties in epistemic rationality tend to generate a requirement to withhold judgment. I argue that epistemic and practical rationality weigh reasons in the same way, but they have different "default biases". Practical rationality is biased toward every option being permissible whereas epistemic rationality is biased toward withholding judgment's be…Read more

    We can often permissibly choose a worse self-interested option over a better altruistic alternative. For example, it is permissible to eat out rather than donate the money to feed five hungry children for a single meal. If we eat out, we do something permissibly partial toward ourselves. If we donate, we go beyond the call of moral duty and do something supererogatory. Such phenomena aren’t easy to explain, and they rule out otherwise promising moral theories. Incommensurability and Ruth Ch…Read more

    Parity, moral options, and the weights of reasons
    Noûs 57 (2): 454-480. 2022.
    The (moral) permissibility of an act is determined by the relative weights of reasons, or so I assume. But how many weights does a reason have? Weight Monism is the idea that reasons have a single weight value. There is just the weight of reasons. The simplest versions hold that the weight of each reason is either weightier than, less weighty than, or equal to every other reason. We’ll see that this simple view leads to paradox in at least two ways. We must complicate the picture somehow. …Read more

    A Holist Balance Scale
    Journal of the American Philosophical Association 9 (3): 533-553. 2023.
    Scale-based models of weighing reasons face challenges concerning the context sensitivity of weight, the aggregation of weight, and the methodology for determining what the weights of reasons are. I resolve these challenges.

    Too far beyond the call of duty: moral rationalism and weighing reasons
    Philosophical Studies 179 (6): 2029-2052. 2021.
    The standard account of supererogation holds that Liv is not morally required to jump on a grenade, thereby sacrificing her life, to save the lives of five soldiers. Many proponents defend the standard account by appealing to moral rationalism about requirement. These same proponents hold that Bernie is morally permitted to jump on a grenade, thereby sacrificing his life, to spare someone a mild burn. I argue that this position is unstable, at least as moral rationalism is ordinarily defended…Read more

    Weighing Reasons Against
    Oxford Studies in Metaethics. forthcoming.
    Ethicists increasingly reject the scale as a useful metaphor for weighing reasons. Yet they generally retain the metaphor of a reason’s weight. This combination is incoherent. The metaphor of weight entails a very specific scale-based model of weighing reasons, Dual Scale. Justin Snedegar worries that scale-based models of weighing reasons can’t properly weigh reasons against an option. I show that there are, in fact, two different reasons for/against distinctions, and I provide an account …Read more

    Philosophers use disagreement as a way to discover truth. It is constructive. It can lead one to refine one's own position and/or better understand the opposing position. When you are comfortable with the people you disagree with, it can be a fun way to learn. It can even build community. Yet students often see disagreement as divisive. There are winners and losers, and it's not much fun when you are losing. Rarely do students actively use it as a tool for better understanding their own p…Read more

    The dual scale model of weighing reasons
    Noûs 56 (2): 366-392. 2021.
    The metaphor of weighing reasons brings to mind a single (double-pan balance) scale. The reasons for φ go in one pan and the reasons for ~φ go in the other. The relative weights, as indicated by the relative heights of the two pans of the scale, determine the deontic status of φ. This model is simple and intuitive, but it cannot capture what it is to weigh reasons correctly. A reason pushes the φ pan down toward permissibility (has justifying weight) only insofar as it pushes the ~φ pan up to…Read more

    Divine Satisficing and the Ethics of the Problem of Evil
    Faith and Philosophy 37 (1): 32-56. 2020.
    This paper accomplishes three goals. First, it reveals that God’s ethics has a radical satisficing structure: God can choose a good enough suboptimal option even if there is a best option and no countervailing considerations. Second, it resolves the long-standing worry that there is no account of the good enough that is both principled and demanding enough to be good enough. Third, it vindicates the key ethical assumption in the problem of evil without relying on the contested assumption that Go…Read more

    Experience as evidence
    In Maria Lasonen-Aarnio & Clayton Littlejohn (eds.), The Routledge Handbook of the Philosophy of Evidence, Routledge. 2023.
    This chapter explores whether and when experience can be evidence. It argues that experiences can be evidence, and that this claim is compatible with just about any epistemological theory. It evaluates the most promising argument for the conclusion that certain experiences (e.g., seeming to see) are always evidence for believing what the experiences represent. While the argument is very promising, one premise needs further defense. The argument also depends on a certain connection between re…Read more

    Perceptual dogmatism is a prominent theory in epistemology concerning the relationship between perceptual experience and reasonable belief. It holds that, in the absence of counterevidence, it is reasonable to believe what your perceptual experience tells you. Thus, if you are not aware of your experience’s casual history, then it doesn’t matter. Critics object that the causal history does matter: when a perceptual experience is caused in certain ways, it is unreasonable to trust what it tell…Read more

    How to Explain Miscomputation
    Philosophers' Imprint 18 1-17. 2018.
    Just as theory of representation is deficient if it can’t explain how misrepresentation is possible, a theory of computation is deficient if it can’t explain how miscomputation is possible. Nonetheless, philosophers have generally ignored miscomputation. My primary goal in this paper is to clarify both what miscomputation is and how to adequately explain it. Miscomputation is a special kind of malfunction: a system miscomputes when it computes in a way that it shouldn’t. To explain miscomput…Read more

    Satisficing and Motivated Submaximization (in the Philosophy of Religion)
    Philosophy and Phenomenological Research 93 (1): 127-143. 2016.
    In replying to certain objections to the existence of God, Robert Adams, Bruce Langtry, and Peter van Inwagen assume that God can appropriately choose a suboptimal world, a world less good than some other world God could have chosen. A number of philosophers, such as Michael Slote and Klaas Kraay, claim that these theistic replies are therefore committed to the claim that satisficing can be appropriate. Kraay argues that this commitment is a significant liability. I argue, however, that the rele…Read more

    Harman Vs. Virtue Theory
    Southwest Philosophy Review 21 (1): 137-145. 2004.
    While there are alternative accounts, many virtue theories are character based, that is, they assert that the primary loci if moral evaluation are a person's character traits. According to these theories, any individual human being is good insogar as she possesses certain character traits, the virtues, and does not possess their antipodes, the vices. Gilbert Harman has attacked this view by citing evidence in empirical psychology that human behaviour is explained by situational factors to the ex…Read more

    Perceptual dogmatism holds that if it perceptually seems to S that P, then S thereby has prima facie perceptual justification for P. But suppose Wishful Willy's desire for gold cognitively penetrates his perceptual experience and makes it seem to him that the yellow object is a gold nugget. Intuitively, his desire-penetrated seeming can't provide him with prima facie justification for thinking that the object is gold. If this intuitive response is correct, dogmatists have a problem. But if dogma…Read more

    Why open-minded people should endorse dogmatism
    Philosophical Perspectives 24 (1): 529-545. 2010.
    Open-minded people should endorse dogmatism because of its explanatory power. Dogmatism holds that, in the absence of defeaters, a seeming that P necessarily provides non-inferential justification for P. I show that dogmatism provides an intuitive explanation of four issues concerning non-inferential justification. It is particularly impressive that dogmatism can explain these issues because prominent epistemologists have argued that it can’t address at least two of them. Prominent epistemol…Read more

    Phenomenal conservatism and evidentialism in religious epistemology
    In Raymond VanArragon & Kelly James Clark (eds.), Evidence and Religious Belief, Oxford University Press. pp. 52--73. 2011.
    Phenomenal conservatism holds, roughly, that if it seems to S that P, then S has evidence for P. I argue for two main conclusions. The first is that phenomenal conservatism is better suited than is proper functionalism to explain how a particular type of religious belief formation can lead to non-inferentially justified religious beliefs. The second is that phenomenal conservatism makes evidence so easy to obtain that the truth of evidentialism would not be a significant obstacle to justified…Read more
