• Can the One-System Picture Be Systematic?
    Law and Philosophy 1. 2026.
    The emergence of the one-system picture is one of the most significant developments within general jurisprudence in decades. The one-system picture promises an account of legal obligations, privileges, powers, and immunities as part of morality. One of its chief contemporary proponents (Greenberg) treats it as thereby offering a new account of legal content, which rivals familiar two-system forms of positivism and antipositivism. The other (Hershovitz) treats it as abandoning the idea of legal c…Read more

    Approving on the Basis of Moral and Aesthetic Testimony
    In Russ Shafer-Landau (ed.), Oxford Studies in Metaethics Volume 16, Oxford University Press. pp. 183-206. 2021.
    While there is a vibrant debate over whether _believing_ or _acting_ on the basis of moral and aesthetic testimony is ‘defective’, most grant that _approving_ on the basis of normative testimony is verboten. The main goal of this chapter is to defend such affective responses to normative testimony and it does this by arguing that philosophers have relied on the wrong comparison cases: we need to compare minimal contrastive pairs, and better and worse cases of approving on the basis of normative …Read more

    Who’s on First?
    In Russ Shafer-Landau (ed.), Oxford Studies in Metaethics Volume 15, Oxford University Press. pp. 49-71. 2020.
    “X-Firsters” hold that there is some normative feature that is fundamental to all others (and, often, that there’s some normative feature that is the “mark of the normative”: all other normative properties have it, and are normative in virtue of having it). This view is taken as a starting point in the debate about which X is “on first.” Little has been said about whether or why we should be X-Firsters, or what we should think about normativity if we aren’t X-Firsters. Hence the chapter’s two ma…Read more

    Expressivism and Varieties of Normativity
    In Russ Shafer-Landau (ed.), Oxford Studies in Metaethics 12, Oxford University Press. pp. 265-293. 2017.
    Expressivists aim to explain the meaning of a fragment of language—typically, claims about what we morally ought to do—in terms of the non-cognitive attitudes they express. Critics evaluate expressivism on those terms. This is a mistake. We don’t use that fragment of language in isolation. We make claims about what we morally, legally, rationally, and prudentially ought to do: we relativize “ought” and other deontic modals to different standards, or varieties of normativity. This chapter argues …Read more

    Law’s Language
    Cambridge University Press. 2025.
    The language of law includes normative or prescriptive terms such as 'obligation' and 'permission'. How do we explain the meaning of prescriptive legal language? This has long been regarded as a problem for positivists, since at first glance their view suggests we can derive an ought – a legal obligation or right or permission – from descriptive social facts alone. This Element outlines what we should want from a semantics of prescriptive legal language, critically evaluates four leading semanti…Read more

    What Voting Power Cannot Be
    Noûs. forthcoming.
    “Almost everyone,” Ronald Dworkin wrote in Sovereign Virtue, “assumes that democracy means equal voting power.” What, then, is voting power? The standard view defines it as the probability that a vote changes the outcome assuming that each possible combination of votes is equiprobable. This has significant implications: institutions like the US Electoral College give disproportionate voting power to voters in large states. But the standard view cannot be true. As an a priori account, it rests on…Read more

    Of Witches and White Folks
    Philosophy and Phenomenological Research 104 (3): 587-605. 2021.
    A central debate in philosophy of race is between eliminativists and conservationists about what we ought do with ‘race’ talk. ‘Eliminativism’ is often defined such that it’s committed to holding that (a) ‘race’ is vacuous and races don’t exist, so (b) we should eliminate the term ‘race’ from our vocabulary. As a stipulative definition, that’s fine. But as an account of one of the main theoretical options in the debate, it’s a serious mistake. I offer three arguments for why eliminativism should…Read more

    Discrimination & Disadvantage
    Philosophers' Imprint. forthcoming.
    Victims of discriminated are often disadvantaged. Are they necessarily disadvantaged? Many say so: “in discriminating against someone, one is necessarily acting to the disadvantage of that someone” (Gardner 2018: 67); “discrimination against someone simply is disadvantageous differential treatment” (Lippert-Rasmussen 2013: 15). The connection between discrimination and disadvantage is also supposed to play two significant explanatory roles. That you are disadvantaged by the differential treatmen…Read more

    In general, otherwise permissible actions do not become wrong when agents act on bad attitudes. But cases of discrimination can be exceptions to this generalization. It could “be morally permissible for someone to rent her house to any one of several prospective tenants but not morally permissible to refuse to rent it to one of those people because of his race” (Scanlon 2008: 71). These two claims are plausible and widely accepted, but they call for explanation. Why is it that in some cases of d…Read more

    Malapportionment: A Murder Mystery
    Northwestern University Law Review 120 561-622. 2025.
    Malapportionment—electoral districts with divergent ratios of people to representation—was ruled to be unconstitutional in a widely venerated series of cases before the Warren Court. Those cases held that a principle of political equality, ‘one person, one vote’, is required by the Constitution. But what is the content of that principle? Many Justices and commentators declare that it is vague, empty, circular, or meaningless. This creates a murder mystery. Malapportionment was killed; but by wha…Read more

    Mandatory Minimums and the War on Drugs
    In David Boonin (ed.), Palgrave Handbook of Philosophy and Public Policy, Palgrave-macmillan. pp. 51-62. 2018.
    Mandatory minimum sentencing provisions have been a feature of the U.S. justice system since 1790. But they have expanded considerably under the war on drugs, and their use has expanded considerably under the Trump Administration; some states are also poised to expand drug-related mandatory minimums further in efforts to fight the current opioid epidemic. In this paper I outline and evaluate three prominent arguments for and against the use of mandatory minimums in the war on drugs—they appeal, …Read more

    What is the Point of Political Equality?
    Philosophical Review 133 (4): 367-413. 2024.
    Political egalitarians hold that there is a distinct ideal of political equality, which defines and justifies democracy. So what is political equality? The orthodox view says it is equality of opportunity for political influence, not equality of political influence. The first goal of this article is to argue against this view about the nature of political equality. From 1962 to 1983, Australia’s First Nations citizens had the right to vote, but unlike other citizens they did not have the duty to…Read more

    One Person, One Vote
    Oxford Studies in Political Philosophy 11 32-59. 2025.
    ‘One person, one vote’ (OPOV) is an important slogan in democratic movements, a principle that undergirds a landmark series of cases in US constitutional law, and a widely accepted axiom of democratic theory in philosophy and political science. It is taken to be sacrosanct; some even state that OPOV “is, like the injustice of chattel slavery, a ‘fixed point’” (Kolodny 2023: 291). This is a rare distinction for an ideal. For all the ink spilt on Rawls’ Difference Principle, no one printed it on t…Read more

    The Democratic Imperative to Make Margins Matter
    Maryland Law Review 86 (2): 365-442. 2023.
    Many commentators lament that American democracy is in crisis. It is becoming a system of minority rule, wherein a party with a minority of the nationwide vote can control the national government. Partisan gerrymandering in the House of Representatives fuels this crisis, as does the equal representation of small and large states in the Senate. But altering these features of the legislature would not end minority rule. Indeed, it has long been held that majority rule cannot be guaranteed within a…Read more

    Regulating Speech: Harm, Norms, and Discrimination
    Inquiry: An Interdisciplinary Journal of Philosophy 1. 2024.
    Mary Kate McGowan’s Just Words offers an interesting account of exercitives. On McGowan’s view, one of the things we do with words is change what’s permitted, and we do this ubiquitously, without any special authority or specific intention. McGowan’s account of exercitives is meant to identify a mechanism by which ordinary speech is harmful, and which justifies the regulation of such speech. It is here that I part ways. I make three main a…Read more

    People’s Beliefs About Pronouns Reflect Both the Language They Speak and Their Ideologies
    with April Bailey, Robin Dembroff, Elif Ikizer, and Andrei Cimpian
    Journal of Experimental Psychology: General 153 (3): 1388-1406. 2024.
    Pronouns often convey information about a person’s social identity (e.g., gender). Consequently, pronouns have become a focal point in academic and public debates about whether pronouns should be changed to be more inclusive, such as for people whose identities do not fit current pronoun conventions (e.g., gender non-binary individuals). Here, we make an empirical contribution to these debates by investigating which social identities lay speakers think that pronouns should encode and why. Across…Read more
  • Quietism
    In David Copp & Connie Rosati (eds.), The Oxford Handbook of Metaethics, Oxford University Press. forthcoming.
    Metaethical quietists agree with realists that moral judgments express beliefs and that some of those beliefs are true. But, quietists continue, this is so even though moral truths lacks truth-makers. To its advocates—including McDowell (1979), Lovibond (1983), Nagel (1997), Dworkin (1996), Rorty (1998), Kramer (2009), Parfit (2011), Scanlon (2014), Crary (2016), and Sepielli (2022)—quietism offers a simple way out of an otherwise intractable quagmire. To its detractors, what it offers is either…Read more

    Which Majority Should Rule?
    Philosophy and Public Affairs 52 (2): 177-220. 2024.
    Majority rule is often regarded as an important democratic principle. But modern democracies divide voters into districts. So if the majority should rule, which majority should rule? Should it be the popular majority, or an electoral majority (i.e., either the majority of voters in the majority of districts, or the majority of voters in districts that contain the majority of the population)? I argue that majority rule requires rule by the popular majority. This view is not novel and may seem obv…Read more

    We argued that formal objections to the error theory overgeneralize and therefore fail. Christine Tiefensee and Gregory Wheeler deny this. We argue that they are wrong, for two reasons. The first concerns how we should adjudicate conflicts between formal and substantive commitments. The second concerns an overlooked tension between formal objections and non-error-theoretic views. Our discussion shows that the commitments behind formal objections to the error theory, such as the dual schema, shou…Read more

    Does Race Best Explain Racial Discrimination?
    Philosophers' Imprint 23. 2023.
    Our concern in this paper lies with a common argument from racial discrimination to realism about races: some people are discriminated against for being members of a particular race (i.e., racial discrimination exists), so some people must be members of that race (i.e., races exist). Error theorists have long responded that we can explain racial discrimination in terms of racial attitudes alone, so we need not explain it in terms of race itself. But to date there has been little detailed discuss…Read more

    The Perversity of Weighted Voting
    Journal of Politics 86 (2): 815-818. 2024.
    Weighted voting involves weighting representatives’ votes by the populations that they represent. Such systems have been adopted in some legislative bodies as a remedy for malapportionment, and are sometimes used to elect candidates for the executive branch of government. But they receive little attention. This note observes the neglected vices of weighted voting systems: they violate intuitive conditions of monotonicity and participation. These vices count significantly against the use of weigh…Read more

    The Disunity of Legal Reality
    Legal Theory 28 (3): 235-267. 2022.
    Take “legal reality” to be the part of reality that actual legal thought and talk is dis- tinctively about, such as legal institutions, legal obligations, and legal norms. Our goal is to explore whether legal reality is disunified. To illustrate the issue, consider the possibility that an important metaphysical thesis such as positivism is true of one part of legal reality (legal institutions), but not another (legal norms). We offer two arguments that suggest that legal reality is disunified: o…Read more

    Legal Positivism and the Real Definition of Law
    Jurisprudence 13 (3): 317-348. 2022.
    We explore an underappreciated tension at the heart of the debate over legal positivism. On the one hand, many legal philosophers aspire for the debate to tell us what law is, and the nature of law. But on the other hand, the positions in the debate are generally formulated such that they’re about something else: what law is necessarily connected to or dependent on. This is a genuine tension, because theses about what law is necessarily connected to or dependent on do not by themselves state or …Read more

    On the (in)significance of Hume’s Law
    Philosophical Studies 179 (2): 633-653. 2022.
    Hume’s Law that one cannot derive an “ought” from an “is” has often been deemed to bear a significance that extends far beyond logic. Repeatedly, it has been invoked as posing a serious threat to views about normativity: naturalism in metaethics and positivism in jurisprudence. Yet in recent years, a puzzling asymmetry has emerged: while the view that Hume’s Law threatens naturalism has largely been abandoned (due mostly to Pigden’s work, see e.g. Pigden 1989), the thought that Hume’s Law is a s…Read more

    Approving on the Basis of Moral and Aesthetic Testimony
    Oxford Studies in Metaethics 16 183-206. 2021.
    If a reliable testifier tells you that a song is beautiful or that an act is wrong, do you thereby have a reason to approve of the painting and disapprove of the agent's action? Many insist that we don’t: normative testimony does not give us reasons for affective attitudes like approval. This answer is often treated as a datum in the literatures on moral and aesthetic testimony. I argue that once we correct for a common methodological mistake in these literatures, the answer must be Yes. I then …Read more

    Why formal objections to the error theory fail
    Analysis 81 (2): 254-262. 2021.
    Many philosophers argue that the error theory should be rejected because it is incompatible with standard deontic logic and semantics. We argue that such formal objections to the theory fail. Our discussion has two upshots. First, it increases the dialectical weight that must be borne by objections to the error theory that target its content rather than its form. Second, it shows that standard deontic logic and semantics should be revised.
