    This study examined correlations between moral value judgments on a 17-item Moral Intuition Survey (MIS), and participant scores on the Short-D3 “Dark Triad” Personality Inventory—a measure of three related “dark and socially destructive” personality traits: Machiavellianism, Narcissism, and Psychopathy. Five hundred sixty-seven participants (302 male, 257 female, 2 transgendered; median age 28) were recruited online through Amazon Mechanical Turk and Yale Experiment Month web advertisements.

    A New Theory of Free Will
    Philosophical Forum 44 (1): 1-48. 2013.
    This paper shows that several live philosophical and scientific hypotheses – including the holographic principle and multiverse theory in quantum physics, and eternalism and mind-body dualism in philosophy – jointly imply an audacious new theory of free will. This new theory, "Libertarian Compatibilism", holds that the physical world is an eternally existing array of two-dimensional information – a vast number of possible pasts, presents, and futures – and the mind a nonphysical entity or set o…Read more

    In a recent study appearing in Neuroethics, I reported observing 11 significant correlations between the “Dark Triad” personality traits – Machiavellianism, Narcissism, and Psychopathy – and “conservative” judgments on a 17-item Moral Intuition Survey. Surprisingly, I observed no significant correlations between the Dark Triad and “liberal” judgments. In order to determine whether these results were an artifact of the particular issues I selected, I ran a follow-up study testing the Dark Triad a…Read more

    Unifying the Categorical Imperative
    Southwest Philosophy Review 28 (1): 217-225. 2012.
    This paper demonstrates something that Kant notoriously claimed to be possible, but which Kant scholars today widely believe to be impossible: unification of all three formulations of the Categorical Imperative. Part 1 of this paper tells a broad-brush story of how I understand Kant’s theory of practical reason and morality, showing how the three formulations of the Categorical Imperative appear to be unified. Part 2 then provides clear textual support for each premise in the argument for my int…Read more

    In my 2013 article, “A New Theory of Free Will”, I argued that several serious hypotheses in philosophy and modern physics jointly entail that our reality is structurally identical to a peer-to-peer (P2P) networked computer simulation. The present paper outlines how quantum phenomena emerge naturally from the computational structure of a P2P simulation. §1 explains the P2P Hypothesis. §2 then sketches how the structure of any P2P simulation realizes quantum superposition and wave-function collap…Read more

    This commentary contends that Larry May’s Hobbesian argument for limitations on sovereignty and lawmaking in Limiting Leviathan does not succeed. First, I show that Hobbes begins with a plausible instrumental theory of normativity. Second, I show that Hobbes then attempts, unsuccessfully—by his own lights—to defend a kind of non-instrumental, moral normativity. Thus, I contend, in order to successfully “limit the Leviathan” of the state, the Hobbesian must provide a sound instrumental argument i…Read more

    First Steps Toward a Nonideal Theory of Justice
    Ethics and Global Politics 7 (3): 95-117. 2014.
    Theorists have long debated whether John Rawls’ conception of justice as fairness can be extended to nonideal (i.e. unjust) social and political conditions, and if so, what the proper way of extending it is. This paper argues that in order to properly extend justice as fairness to nonideal conditions, Rawls’ most famous innovation – the original position – must be reconceived in the form of a “nonideal original position.” I begin by providing a new analysis of the ideal/nonideal theory distincti…Read more

    How to rationally approach life's transformative experiences
    Philosophical Psychology 28 (8): 1199-1218. 2015.
    In a widely discussed forthcoming article, “What you can't expect when you're expecting,” L. A. Paul challenges culturally and philosophically traditional views about how to rationally make major life-decisions, most specifically the decision of whether to have children. The present paper argues that because major life-decisions are transformative, the only rational way to approach them is to become resilient people: people who do not “over-plan” their lives or expect their lives to play out “ac…Read more

    David. J. Chalmers examines eleven possible solutions to the meta-problem of consciousness, ‘the problem of explaining why we think that there is a problem of consciousness.’ The present paper argues that Chalmers overlooks an explanation that he has otherwise taken seriously, and which a number of philosophers, physicists, and computer scientists have taken seriously as well: the hypothesis that we are living in a computer simulation. This paper argues that a particular version of the simulatio…Read more

    Reconceptualizing human rights
    Journal of Global Ethics 8 (1): 91-105. 2012.
    This paper defends several highly revisionary theses about human rights. Section 1 shows that the phrase 'human rights' refers to two distinct types of moral claims. Sections 2 and 3 argue that several longstanding problems in human rights theory and practice can be solved if, and only if, the concept of a human right is replaced by two more exact concepts: (A) International human rights, which are moral claims sufficient to warrant coercive domestic and international social protection; and (B) …Read more

    The Dark Side of Morality: Group Polarization and Moral Epistemology
    Philosophical Forum 50 (1): 87-115. 2019.
    This article argues that philosophers and laypeople commonly conceptualize moral truths or justified moral beliefs as discoverable through intuition, argument, or some other purely cognitive or affective process. It then contends that three empirically well-supported theories all predict that this ‘Discovery Model’ of morality plays a substantial role in causing social polarization. The same three theories are then used to argue that an alternative ‘Negotiation Model’ of morality—according to wh…Read more

    Two New Doubts about Simulation Arguments
    Australasian Journal of Philosophy 100 (3): 496-508. 2022.
    Various theorists contend that we may live in a computer simulation. David Chalmers in turn argues that the simulation hypothesis is a metaphysical hypothesis about the nature of our reality, rather than a sceptical scenario. We use recent work on consciousness to motivate new doubts about both sets of arguments. First, we argue that if either panpsychism or panqualityism is true, then the only way to live in a simulation may be as brains-in-vats, in which case it is unlikely that we live in a s…Read more

    A Better, Dual Theory of Human Rights
    Philosophical Forum 45 (1): 17-47. 2014.
    Human rights theory and practice have long been stuck in a rut. Although disagreement is the norm in philosophy and social-political practice, the sheer depth and breadth of disagreement about human rights is truly unusual. Human rights theorists and practitioners disagree – wildly in many cases – over just about every issue: what human rights are, what they are for, how many of them there are, how they are justified, what human interests or capacities they are supposed to protect, what they re…Read more

    Alex Byrne contends that women are (simply) adult human females, claiming that this thesis has considerably greater initial appeal than the justified true belief (JTB) theory of knowledge. This paper refutes Byrne’s thesis in the same way the JTB theory of knowledge is widely thought to have been refuted: through simple counterexamples. Lessons are drawn. One lesson is that women need not be human. A second lesson is that biology and physical phenotypes are both irrelevant to whether someone is …Read more

    Allies Against Oppression: Intersectional Feminism, Critical Race Theory, and Rawlsian Liberalism
    Journal of Ethics and Social Philosophy 26 (2): 221-266. 2023.
    Liberalism is often claimed to be at odds with feminism and critical race theory (CRT). This article argues, to the contrary, that Rawlsian liberalism supports the central commitments of both. Section 1 argues that Rawlsian liberalism supports intersectional feminism. Section 2 argues that the same is true of CRT. Section 3 then uses Young’s ‘Five Faces of Oppression’—a classic work widely utilized in feminism and CRT to understand and contest many varieties of oppression—to illustrate how Rawls…Read more

    Mental time-travel, semantic flexibility, and A.I. ethics
    AI and Society 38 (6): 2577-2596. 2023.
    This article argues that existing approaches to programming ethical AI fail to resolve a serious moral-semantic trilemma, generating interpretations of ethical requirements that are either too semantically strict, too semantically flexible, or overly unpredictable. This paper then illustrates the trilemma utilizing a recently proposed ‘general ethical dilemma analyzer,’ GenEth. Finally, it uses empirical evidence to argue that human beings resolve the semantic trilemma using general cognitive an…Read more

    Nonideal Justice as Nonideal Fairness
    Journal of the American Philosophical Association 5 (2): 208-228. 2019.
    This article argues that diverse theorists have reasons to theorize about fairness in nonideal conditions, including theorists who reject fairness in ideal theory. It then develops a new all-purpose model of ‘nonideal fairness.’ §1 argues that fairness is central to nonideal theory across diverse ideological and methodological frameworks. §2 then argues that ‘nonideal fairness’ is best modeled by a nonideal original position adaptable to different nonideal conditions and background normative fra…Read more

    Panpsychism and AI consciousness
    Synthese 200 (3): 1-22. 2022.
    This article argues that if panpsychism is true, then there are grounds for thinking that digitally-based artificial intelligence may be incapable of having coherent macrophenomenal conscious experiences. Section 1 briefly surveys research indicating that neural function and phenomenal consciousness may be both analog in nature. We show that physical and phenomenal magnitudes—such as rates of neural firing and the phenomenally experienced loudness of sounds—appear to covary monotonically with th…Read more

    This book argues that moral philosophy should be based on seven scientific principles of theory selection. It then argues that a new moral theory—Rightness as Fairness—satisfies those principles more successfully than existing theories. Chapter 1 explicates the seven principles of theory-selection, arguing that moral philosophy must conform to them to be truth-apt. Chapter 2 argues those principles jointly support founding moral philosophy in known facts of empirical moral psychology: specifical…Read more

    Varieties of Artificial Moral Agency and the New Control Problem
    Humana.Mente - Journal of Philosophical Studies 15 (42): 225-256. 2022.
    This paper presents a new trilemma with respect to resolving the control and alignment problems in machine ethics. Section 1 outlines three possible types of artificial moral agents (AMAs): (1) 'Inhuman AMAs' programmed to learn or execute moral rules or principles without understanding them in anything like the way that we do; (2) 'Better-Human AMAs' programmed to learn, execute, and understand moral rules or principles somewhat like we do, but correcting for various sources of human moral erro…Read more

    Groundwork for a New Moral Epistemology
    Klesis 27 155-190. 2013.
    This paper argues that virtue ethics and prevailing epistemic norms in moral and political philosophy more generally both support a new kind of empirically-informed moral-virtue epistemology, or “experimental ethics” – an epistemology according to which disputed normative premises in moral and political philosophy should be epistemically evaluated on the basis of empirically-observed relationships they bear to morally admirable and morally repugnant psycho-behavioral traits, as defined by cross-…Read more

    Educational Justice and School Boosting
    Social Theory and Practice 50 (1): 1-31. 2024.
    School boosters are tax-exempt organizations that engage in fundraising efforts to provide public schools with supplementary resources. This paper argues that prevailing forms of school boosting are defeasibly unjust. Section 1 shows that inequalities in public education funding in the United States violate John Rawls’s two principles of domestic justice. Section 2 argues that prevailing forms of school boosting exacerbate and plausibly perpetuate these injustices. Section 3 then contends that b…Read more

    Justice as Fairness in a Broken World
    Philosophy and Public Issues - Filosofia E Questioni Pubbliche 4 (2): 95-126. 2014.
    In Ethics for a Broken World : Imagining Philosophy after Catastrophe, Tim Mulgan applies a number of influential moral and political theories to a “broken world ”: a world of environmental catastrophe in which resources are insufficient to meet everyone’s basic needs. This paper shows that John Rawls’ conception of justice as fairness has very different implications for a broken world than Mulgan suggests it does. §1 briefly summarizes Rawls’ conception of justice, including how Rawls uses a hy…Read more

    Allen Buchanan has argued that a widely defended view of the nature of the state – the view that the state is a discretionary association for the mutual advantage of its members – must be rejected because it cannot adequately account for moral requirements of humanitarian intervention. This paper argues that Buchanan’s objection is unsuccessful,and moreover, that discretionary association theories can preserve an important distinction that Buchanan’s alternative approach to political legitimacy …Read more

    In, “Why Nothing Mental is Just in The Head,” Justin Fisher (Noȗs, 2007) uses a novel thought-experiment to argue that every form of mental internalism is false. This paper shows that Fisher fails to refute mental internalism, and that a new variant of his example actually (a) confirms a form of mental internalism, as well as (b) John Locke's “resemblance thesis,” thereby (c) disconfirming all externalist theories of mental content (the type of theory Fisher takes his original example to prove)…Read more

    People Do Not Have a Duty to Avoid Voting Badly: Reply to Brennan
    Journal of Ethics and Social Philosophy 5 (1): 1-6. 2010.
    Jason Brennan argues that people are morally obligated not to vote badly, where voting badly is voting “without sufficient reason” for harmful or unjust policies or candidates. His argument is: (1) One has an obligation not to engage in collectively harmful activities when refraining from such activities does not impose significant personal costs. (2) Voting badly is to engage in a collectively harmful activity, while abstaining imposes low personal costs. (3) Therefore, one should not vote ba…Read more

    A Nonideal Theory of Justice
    Dissertation, University of Arizona. 2008.
    This dissertation defends a “non-ideal theory” of justice: a systematic theory of how to respond justly to injustice. Chapter 1 argues that contemporary political philosophy lacks a non-ideal theory of justice, and defends a variation of John Rawls’ famous original position – a Non-Ideal Original Position – as a method with which to construct such a theory. Chapter 1 then uses the Non-Ideal Original Position to argue for a Fundamental Principle of Non-Ideal Theory: a principle that requires in…Read more

    Jury Theorems for Peer Review
    British Journal for the Philosophy of Science. forthcoming.
    Peer review is often taken to be the main form of quality control on academic research. Usually journals carry this out. However, parts of maths and physics appear to have a parallel, crowd-sourced model of peer review, where papers are posted on the arXiv to be publicly discussed. In this paper we argue that crowd-sourced peer review is likely to do better than journal-solicited peer review at sorting papers by quality. Our argument rests on two key claims. First, crowd-sourced peer review will…Read more
