    Rethinking Reductive Realism in Ethics
    Dissertation, University of Southern California. 2017.
    Reductive Realism in ethics is the view that it is possible to locate morality in the world as science and experience reveal it to us. Many opponents of Reductive Realism forcefully complain that the view fails to take morality seriously. I develop responses to several versions of this kind of criticism. Taking inspiration from well-developed debates about the nature of phenomenal consciousness in the philosophy of mind, I suggest that the apparent failure of Reductive Realism to respect the sig…Read more

    Honesty and Bad Faith
    Political Philosophy 3 (1). 2026.
    An appealing account of dishonesty subsumes it under the paradigm of lying. However, the account faces clear trouble from a wide range of cases, including cases of bullshit and brazen dishonesty. Such cases show not only that lying is inessential to dishonesty but also that honesty requires more than the absence of dishonesty. We propose an alternative account grounded in norms associated with games. On our account, dishonesty is better understood in terms of cheating or of breaking the rules of…Read more

    Metaethical reductive naturalism is said to be objectionable because (i) it cannot explain the role(s) of moral laws or principles, (ii) it cannot capture morality’s importance, and (iii) it cannot account for morality’s objectivity. In this chapter, I argue that these charges are interestingly united because each turns on various presuppositions about human nature. Reflecting on these presuppositions helps the reductivist fully address charges (i) and (ii). I conclude by arguing that while refl…Read more

    Sometimes we want to have sex with someone but our bodies don’t respond accordingly. Sometimes our bodies respond accordingly but we don’t have the corresponding desire. Sex researchers call this phenomenon “nonconcordance”. Nonconcordance makes interesting trouble for influential internalist views of sexual orientation that locate its nature “in the head”, such as views on which sexual orientation supervenes only on desires, phenomenal experiences of arousal, hybrid states thereof, and the like…Read more

    A central metaphysical debate about laws concerns whether they govern or merely summarize. This debate has recently been extended to moral laws, with fresh criticism directed at the Humean position by, inter alia, David Enoch and Daniel Fogal & Olle Risberg. These criticisms have seemed compelling, we think, because a contemporary Humean metaphysics of moral laws has only been offered implicitly or with important metaphysical concessions. Our aim, therefore, is to sketch the first explicitly Hum…Read more

    Honest AI
    In Henry Shevlin (ed.), Oxford Intersections: AI in Society, Oxford University Press. 2025.
    How would OpenAI’s ChatGPT, Google’s Gemini, Anthropic’s Claude, and other “Conversational” artificially intelligent systems interact with humans if they safely benefited humanity? “Truthfully” is one influential answer defended by machine learning researchers. Drawing on Thomas Hurka’s influential work on value asymmetries in moral philosophy, I argue that a more promising approach to designing safe and beneficial conversational AI systems is to design them to be honest. I do this by rebutting …Read more

    Skepticism About Ought Simpliciter Skepticism
    Inquiry: An Interdisciplinary Journal of Philosophy. 2026.
    Normative pluralists claim that there cannot be facts about what agents ought or “ought simpliciter” to do when an agent’s reasons from different normative systems (e.g. morality, prudence, aesthetics, etc.) don’t all support the same action. Moral philosophers have embraced the normative pluralist’s claim since at least Sidgwick appeared to do so toward the end of the 19th century. I cast doubt on the normative pluralist’s claim by highlighting some of its implausible normative-cum-metaphysical…Read more

    Gender Unrealism
    Ergo: An Open Access Journal of Philosophy. forthcoming.
    While intimately familiar, gender eludes theorizing. We argue that well-known challenges to gender’s analysis originate in a subtle ambiguity: questions about gender sometimes express questions about gender categories themselves (e.g., womanhood, manhood, and so on), while at other times expressing questions about what makes someone a member of these categories. Distinguishing these questions accentuates gender’s connections to morality, making a novel “antirealist” view of gender, or as we call…Read more

    In a recent letter, Dillion et. al (2023) make various suggestions regarding the idea of artificially intelligent systems, such as large language models, replacing human subjects in empirical moral psychology. We argue that human subjects are in various ways indispensable.

    The Stuff That Matters
    In Russ Shafer-Landau (ed.), Oxford Studies of Metaethics 19, Oxford University Press Usa. 2024.
    On one way of talking about a traditional metaethical topic, realists accept that some items appear on the list of what exists in the moral or more broadly normative domain of inquiry. They then divide over whether those items are like what science and experience suggest that all other items on the list of what exists across all domains are like – naturalistic and secular. Reductive naturalists answer this further question affirmatively. Why don’t nonnaturalists? I explore the answer that it’s b…Read more

    Some rules seem more important than others. The moral rule to keep promises seems more important than the aesthetic rule not to wear brown with black or the pool rule not to scratch on the eight ball. A worrying number of metaethicists are increasingly tempted to explain this difference by appealing to something they call “authoritative normativity”. It’s because moral rules are “authoritatively normative” that they are especially important. The authors of this chapter argue for three claims con…Read more

    Categorical phenomenalism about sexual orientation
    Philosophy and Phenomenological Research 106 (3): 581-596. 2022.
    What is sexual orientation? The contemporary consensus among philosophers is that it is a disposition. Unsurprisingly, recent debates about the metaphysics of sexual orientation are almost entirely intramural. Behavioral dispositionalists argue that sexual orientation is a disposition to behave sexually. Desire dispositionalists argue that it is a disposition to desire sexually. We argue that sexual orientation is not best understood in terms of dispositions to behave or dispositions to desire b…Read more

    Phenomenal Concepts as Complex Demonstratives
    Res Philosophica 98 (3): 499-508. 2021.
    There’s a long but relatively neglected tradition of attempting to explain why many researchers working on the nature of phenomenal consciousness think that it’s hard to explain.1 David Chalmers argues that this “meta-problem of consciousness” merits more attention than it has received. He also argues against several existing explanations of why we find consciousness hard to explain. Like Chalmers, we agree that the meta-problem is worthy of more attention. Contra Chalmers, however, we argue tha…Read more

    What Makes Normative Concepts Normative
    Southwest Philosophy Review 37 (1): 45-51. 2021.
    When asked which of our concepts are normative concepts, metaethicists would be quick to list such concepts as GOOD, OUGHT, and REASON. When asked why such concepts belong on the list, metaethicists would be much slower to respond. Matti Eklund is a notable exception. In his recent book, Choosing Normative Concepts, Eklund argues by elimination for “the Normative Role view” that normative concepts are normative in virtue of having a “normative role” or being “used normatively”. One view that Ekl…Read more

    Non-Analytical Naturalism and the Nature of Normative Thought: A Reply to Parfit
    Journal of Ethics and Social Philosophy 9 (1): 1-5. 2015.
    Metaethical non-analytical naturalism consists in the metaphysical thesis that normative properties are identical with or reducible to natural properties and the epistemological thesis that we cannot come to a complete understanding of the nature of normative properties via conceptual analysis alone. In On What Matters, Derek Parfit (2011) argues that non-analytical naturalism is either false or incoherent. In § 1, I show that his argument for this claim is unsuccessful, by showing that it rests…Read more

    Epistemic modesty in ethics
    Philosophical Studies 175 (7): 1577-1596. 2018.
    Many prominent ethicists, including Shelly Kagan, John Rawls, and Thomas Scanlon, accept a kind of epistemic modesty thesis concerning our capacity to carry out the project of ethical theorizing. But it is a thesis that has received surprisingly little explicit and focused attention, despite its widespread acceptance. After explaining why the thesis is true, I argue that it has several implications in metaethics, including, especially, implications that should lead us to rethink our understandin…Read more

    The sense of incredibility in ethics
    Philosophical Studies 176 (1): 93-115. 2019.
    It is often said that normative properties are “just too different” to reduce to other kinds of properties. This suggests that many philosophers find it difficult to believe reductive theses in ethics. I argue that the distinctiveness of the normative concepts we use in thinking about reductive theses offers a more promising explanation of this psychological phenomenon than the falsity of Reductive Realism. To identify the distinctiveness of normative concepts, I use resources from familiar Hybr…Read more

    Wronging by Requesting
    In Mark Timmons (ed.), Oxford Studies in Normative Ethics, Volume 11, Oxford University Press. 2022.
    Upon doing something generous for someone with whom you are close, some kind of reciprocity may be appropriate. But it often seems wrong to actually request reciprocity. This chapter explores the wrongness in making these requests, and why they can nevertheless appear appropriate. After considering several explanations for the wrongness at issue (involving, e.g. distinguishing oughts from obligation, the suberogatory, imperfect duties, and gift-giving norms), a novel proposal is advanced. The re…Read more

    Resisting Reductive Realism
    In Russ Shafer-Landau (ed.), Oxford Studies in Metaethics Volume 15, Oxford University Press. 2020.
    Ethicists struggle to take reductive views seriously. They also have trouble conceiving of some supervenience failures. Understanding why provides further evidence for a kind of hybrid view of normative concept use.

    The World is Not Enough
    Noûs 55 (1): 86-101. 2019.
    Throughout his career, Derek Parfit made the bold suggestion, at various times under the heading of the "Normativity Objection," that anyone in possession of normative concepts is in a position to know, on the basis of their competence with such concepts alone, that reductive realism in ethics is not even possible. Despite the prominent role that the Normativity Objection plays in Parfit's non-reductive account of the nature of normativity, when the objection hasn't been ignored, it's been criti…Read more

    Moral Constraints on Gender Concepts
    Ethical Theory and Moral Practice 23 (1): 39-51. 2020.
    Are words like ‘woman’ or ‘man’ sex terms that we use to talk about biological features of individuals? Are they gender terms that we use to talk about non-biological features e.g. social roles? Contextualists answer both questions affirmatively, arguing that these terms concern biological or non-biological features depending on context. I argue that a recent version of contextualism from Jennifer Saul that Esa Diaz-Leon develops doesn't exhibit the right kind of flexibility to capture our theor…Read more

    Moral Realism, Speech Act Diversity, and Expressivism
    Philosophical Quarterly 69 (274): 166-174. 2019.
    In his highly engaging book, Speech and Morality, Terence Cuneo advances a transcendental argument for moral realism from the fact that we speak. After summarizing the major moves in the book, I argue that its master argument is not as friendly to non-naturalist versions of moral realism as Cuneo advertises and relies on a diet of insufficient types of speech acts. I also argue that expressivists have compelling replies to each of Cuneo's objections individually, but taken together, Cuneo's obje…Read more

    In Unbelievable Errors, Bart Streumer argues via elimination for a global error theory, according to which all normative judgments ascribe properties that do not exist. Streumer also argues that it is not possible to believe his view, which is a claim he uses in defending his view against several objections. I argue that reductivists and nonreductivists have compelling responses to Streumer's elimination argument – responses constituting strong reason to reject Streumer’s diagnosis of any allege…Read more

    Conceptual Analysis in Metaethics
    In Tristram McPherson & David Plunkett (eds.), The Routledge Handbook of Metaethics, Routledge. pp. 536-551. 2017.
    A critical survey of various positions on the nature, use, possession, and analysis of normative concepts. We frame our treatment around G.E. Moore’s Open Question Argument, and the ways metaethicists have responded by departing from a Classical Theory of concepts. In addition to the Classical Theory, we discuss synthetic naturalism, noncognitivism (expressivist and inferentialist), prototype theory, network theory, and empirical linguistic approaches. Although written for a general philosoph…Read more

    Analytic reductivism in metaethics has long been out of philosophical vogue. In Confusion of Tongues: A Theory of Normativity (2014), Stephen Finlay tries to resuscitate it by developing an analytic metaethical reductive naturalistic semantics for ‘good.’ He argues that an end-relational semantics is the simplest account that can explain all of the data concerning the term, and hence the most plausible theory of it. I argue that there are several assumptions that a reductive naturalist would nee…Read more
