8Humanity's Dilemma before Abaddon's GateIn Jeffery L. Nicholas (ed.), The Expanse and Philosophy, Wiley. 2021-10-12.James Holden manages to convince an alien technology—Abaddon's Gate, created by the protomolecule—that human beings are not a threat. It opens up 1,300 Einstein‐Rosen bridges, providing humanity access to at least as many habitable worlds. Humanity faces a dilemma at the start of the fourth season of The Expanse. The very first words of The Expanse appear on a title card: In the twenty‐third century, humans have colonized the solar system. Of course, The Expanse is a work of science fiction, and…Read more

11Medical Deportation, Non-Citizen PatientsIn Elizabeth Victor & Laura K. Guidry-Grimes (eds.), Applying Nonideal Theory to Bioethics: Living and Dying in a Nonideal World, Springer. pp. 357-374. 2021.This chapter is an investigation of the morality of medical deportation, the practice of returning undocumented migrants, despite their ill health and/or injuries, to their countries of origin. In Sect. 16.1, I look more closely at the nature of medical deportation. In Sect. 16.2, I argue that understanding the morality of medical deportation requires nonideal theory. In Sect. 16.3, I outline contractualism as a nonideal theory. In Sect. 16.4, I apply contractualism to medical deportation and ma…Read more

197The Place of Political Forgiveness in Jus post BellumIn Court Lewis (ed.), Underrepresented Perspectives on Forgiveness, Vernon Press. forthcoming.Jus post Bellum is, like Jus ad Bellum and Jus in Bello, a part of just war theory. Jus post Bellum is distinguished from the other parts of just war theory by being primarily concerned with the principles necessary for securing a just and lasting peace after the end of a war. Traditionally, jus post bellum has focused primarily on three goals: [1] compensating those who have been the victims of unjust aggression, while respecting the rights of the aggressors, [2] punishing and rehabilitating th…Read more

121Is There an Obligation to Abort? Act Utilitarianism and the Ethics of ProcreationEssays in Philosophy 20 (1): 24-41. 2019.Most Act-Utilitarians, including Singer are Permissivists who claim that their theory usually permits abortion. In contrast, a minority, including Hare and Tännsjö, are Restrictionists who assert that Act-Utilitarianism usually limits abortion. I argue that both Permissivists and Restrictionists have misunderstood AU’s radical implications for abortion: AU entails that abortion is, in most cases in the economically developed world, morally obligatory. According to AU, it is morally obligatory fo…Read more

164Review Article: Legal Theory, Law, and NormativityJournal of Moral Philosophy 9 (1): 115-126. 2012.Joseph Raz's new book, Between Authority and Interpretation , collects his most important papers in the philosophy of law and the theory of practical rationality from the mid-1990s to the mid-2000s. In these papers, Raz not only advances earlier theses but also breaks new ground in a number of areas. I focus on three of Raz's topics here: theories of law, separability and necessity, and the normativity of law. While I am generally sympathetic to Raz's thinking on these topics, I raise some room …Read more

61Conflict, Regret, and Modern Moral PhilosophyIn Thom Brooks (ed.), New Waves in Ethics, Palgrave-macmillan. 2011.I begin this paper by discussing the difference between outweighing and canceling in conflicts of normativity. I then introduce a thought experiment that I call Crash Drive,and I use it to explain the nature of a certain kind of moral conflict as well as the appropriate emotional response – regret – on the part of the primary agent in this case. Having done this, I turn to a line of criticism opened by Bernard Williams and recently expanded by Jonathan Dancy according to which archetypal examp…Read more

216Moral Blameworthiness and the Reactive AttitudesEthical Theory and Moral Practice 14 (2): 131-142. 2011.In this paper, I present and defend a novel version of the Reactive Attitude account of moral blameworthiness. In Section 1, I introduce the Reactive Attitude account and outline Allan Gibbard's version of it. In Section 2, I present the Wrong Kind of Reasons Problem, which has been at the heart of much recent discussion about the nature of value, and explain why a reformulation of it causes serious problems for versions of the Reactive Attitude account such as Gibbard's. In Section 3, I conside…Read more

91Just War Theory and Cyber-AttacksIn Not Just Wars, . 2013.In this chapter, I take up the question of whether one of the central principles of jus ad bellum – just cause – is relevant in a world in which cyberattacks occur. I argue that this principle is just as relevant as ever, though it needs modification in light of recent developments. In particular, I argue, contrary to many traditional just war theorists, that just cause should not be limited to physical attacks. In the process, I offer an improved definition of cyberattack and show how some othe…Read more

157Rule consequentialism and disastersPhilosophical Studies 162 (2): 219-236. 2013.Rule consequentialism (RC) is the view that it is right for A to do F in C if and only if A's doing F in C is in accordance with the the set of rules which, if accepted by all, would have consequences which are better than any alternative set of rules (i.e., the ideal code). I defend RC from two related objections. The first objection claims that RC requires obedience to the ideal code even if doing so has disastrous results. Though some rule consequentialists embrace a disaster-clause which per…Read more

62The Objection from Justice and the Conceptual/Substantive DistinctionIn Mill on Justice, Palgrave-macmillan. pp. 198. 2012.I begin this chapter by outlining Mill's thinking about why justice is a problem for utilitarians. Next, I turn to Mill's own account of justice and explain its connection with rights, perfect duties, and harms. I then examine David Lyons' answer to the question of how Mill's account is meant to answer the Weak Objection from Justice. Lyons maintains that Mill's account of justice has both a conceptual side and a substantive side. The former provides an analysis of such concepts as 'justice'…Read more
