    The idea that human beings are intellectually self-governing plays two roles in free-speech theory. First, this idea is frequently called upon as part of the justification for free speech. Second, it plays a role in guiding the translation of free-speech principles into legal policy by underwriting the ascriptive framework through which responsibility for certain kinds of speech harms can be ascribed. After mapping out these relations, I ask what becomes of them once we acknowledge certain very …Read more

    Review of Seana Shiffrin, "Speech Matters: On Lying, Morality, and the Law" (review)
    Notre Dame Philosophical Reviews 2015. 2015.
    In this review I critically digest the main themes of Shiffrin's arguments, with a focus on the question of whether her "thinker-based" theory of free speech has different, or more ambivalent, practical implications for free speech policy than she allows.

    Climate Change, Cooperation, and Moral Bioenhancement
    Journal of Medical Ethics 42 (2): 742-747. 2016.
    The human faculty of moral judgment is not well suited to address problems, like climate change, that are global in scope and remote in time. Advocates of ‘moral bioenhancement’ have proposed that we should investigate the use of medical technologies to make human beings more trusting and altruistic, and hence more willing to cooperate in efforts to mitigate the impacts of climate change. We survey recent accounts of the proximate and ultimate causes of human cooperation in order to assess the p…Read more

    Moral Antitheodicy: Prospects and Problems
    International Journal for Philosophy of Religion 65 (3): 153-169. 2008.
    Proponents of the view which I call ‘moral antitheodicy’ call for the theistic discourse of theodicy to be abandoned, because, they claim, all theodicies involve some form of moral impropriety. Three arguments in support of this view are examined: the argument from insensitivity, the argument from detachment, and the argument from harmful consequences. After discussing the merits of each argument individually, I attempt to show that they all must presuppose what they are intended to establish, n…Read more

    Nanotechnologically Enhanced Combat Systems: The Downside of Invulnerability
    In Bert Gordijn & Anthony Mark Cutter (eds.), In Pursuit of Nanoethics, Springer. pp. 89-103. 2014.
    In this paper we examine the ethical implications of emerging Nanotechnologically Enhanced Combat Systems (or 'NECS'). Through a combination of materials innovation and biotechnology, NECS are aimed at making combatants much less vulnerable to munitions that pose a lethal threat to soldiers protected by conventional armor. We argue that increasing technological disparities between forces armed with NECS and those without will exacerbate the ethical problems of asymmetric warfare. This will place…Read more

    Super Soldiers and Technological Asymmetry
    In Jai Galliott & Mianna Lotz (eds.), Super Soldiers: The Ethical, Legal and Social Implications, Ashgate. pp. 81-91. 2015.
    In this chapter I argue that emerging soldier enhancement technologies have the potential to transform the ethical character of the relationship between combatants, in conflicts between ‘Superpower’ militaries, with the ability to deploy such technologies, and technologically disadvantaged ‘Underdog’ militaries. The reasons for this relate to Paul Kahn’s claims about the paradox of riskless warfare. When an Underdog poses no threat to a Superpower, the standard just war theoretic justifications …Read more

    Dignity, Harm, and Hate Speech
    Law and Philosophy 32 (6): 701-728. 2013.
    This paper examines two recent contributions to the hate speech literature – by Steven Heyman and Jeremy Waldron – which seek a justification for the legal restriction of hate speech in an account of the way that hate speech infringes against people’s dignity. These analyses look beyond the first-order hurts and disadvantages suffered by the immediate targets of hate speech, and consider the prospect of hate speech sustaining complex social structures whose wide-scale operations lower the social…Read more

    Moral Renegades (review)
    The New Rambler Review 2016. 2016.
    This piece is a side-by-side review of two books: Strangers Drowning, by Larissa MacFarquhar, and Doing Good Better, by William MacAskill. Both books are concerned with the question of whether we should try to live as morally good a life as possible. MacAskill thinks the answer is 'yes', and his book is an overview of how the Effective Altruist movement approaches the problem of how to achieve a morally optimal life. MacFarquhar's book is a more descriptive account of the lives of people who aim…Read more

    Some Moral Critique of Theodicy is Misplaced, But Not All
    Religious Studies 45 (3): 339-346. 2009.
    Several recent critiques of theodicy have incorporated some form of moral objection to the theodical enterprise, in which the critic argues that one ought not to engage in the practice of theodicy. In defending theodical practice against the moral critique, Atle O. Søvik argues that the moral critique (1) begs the question against theodicy, and (2) misapprehends the implications of the claim that it is inappropriate to espouse a theodicy in certain situations. In this paper I suggest some sympat…Read more

    Life in Overabundance: Agar on Life-Extension and the Fear of Death
    with Aveek Bhattacharya
    Ethical Theory and Moral Practice 17 (2): 223-236. 2014.
    In Humanity’s End: Why We Should Reject Radical Enhancement, Nicholas Agar presents a novel argument against the prospect of radical life-extension. Agar’s argument hinges on the claim that extended lifespans will result in people’s lives being dominated by the fear of death. Here we examine this claim and the surrounding issues in Agar’s discussion. We argue, firstly, that Agar’s view rests on empirically dubious assumptions about human rationality and attitudes to risk, and secondly, that even…Read more

    Dehumanization: its Operations and its Origins
    Journal of Law and Biosciences 3 (1): 178-184. 2016.
    Gail Murrow and Richard Murrow offer a novel account of dehumanization, by synthesizing data which suggest that where subject S has a dehumanized view of group G, S‘s neural mechanisms of empathy show a dampened response to the suffering of members of G, and S‘s judgments about the humanity of members of G are largely non-conscious. Here I examine Murrow and Murrow‘s suggestions about how identity-based hate speech bears responsibility for dehumanization in the first place. I identify a distinct…Read more

    Epistemic Peerhood and the Epistemology of Disagreement
    Philosophical Studies 164 (2): 561-577. 2013.
    In disagreements about trivial matters, it often seems appropriate for disputing parties to adopt a ‘middle ground’ view about the disputed matter. But in disputes about more substantial controversies (e.g. in ethics, religion, or politics) this sort of doxastic conduct can seem viciously acquiescent. How should we distinguish between the two kinds of cases, and thereby account for our divergent intuitions about how we ought to respond to them? One possibility is to say that ceding ground in a t…Read more

    Permissivism and the Arbitrariness Objection
    Episteme 14 (4): 519-538. 2017.
    Permissivism says that for some propositions and bodies of evidence, there is more than one rationally permissible doxastic attitude that can be taken towards that proposition given the evidence. Some critics of this view argue that it condones, as rationally acceptable, sets of attitudes that manifest an untenable kind of arbitrariness. I begin by providing a new and more detailed explication of what this alleged arbitrariness consists in. I then explain why Miriam Schoenfield’s prima facie pro…Read more
