    Principles of procreative beneficence (PPBs) hold that parents have good reasons to select the child with the best life prospects. Sparrow (2010) claims that PPBs imply that we should select only female children, unlesswe attach normative significance to “normal” human capacities. We argue that this claim fails on both empirical and logical grounds. Empirically, Sparrow’s argument for greater female wellbeing rests on a selective reading of the evidence and the incorrect assumption that an advan…Read more

    In Defense of the Wide-Scope Instrumental Principle
    Journal of Ethics and Social Philosophy 5 (2): 1-21. 2010.
    I make the observation that English sentences such as “You have reason to take the bus or to take the train” do not have the logical form that they superficially appear to have. I find in these sentences a conjunctive use of “or,” as found in sentences like “You can have milk or lemon in your tea,” which gives you a permission to have milk, and a permission to have lemon, though no permission to have both. I argue that a confusion of genuine disjunctions with sentences of the above form has moti…Read more

    Organ Markets and Disrespectful Demands
    International Journal of Applied Philosophy 31 (2): 119-136. 2017.
    There is a libertarian argument for live donor organ markets, according to which live donor organ markets would be permitted if we simply refrained from imposing any substantive and controversial moral assumptions on people who reasonably disagree about morality and justice. I argue that, to the contrary, this endorsement of live donor organ markets depends upon the libertarians’ adoption of a substantive and deeply controversial conception of strong, extensive property rights. This is shown by …Read more

    This chapter describes a philosophical approach to theorizing justice, mapping out some main strands of the tradition leading up to contemporary political philosophy. We first briefly discuss what distinguishes a philosophical approach to justice from other possible approaches to justice, by explaining the normative focus of philosophical theories of justice – that is, a focus on questions not about how things actually are, but about how things ought to be. Next, we explain what sorts of methods…Read more

    This chapter describes how philosophical theorizing about justice can be connected with empirical research in the social sciences. We begin by drawing on some received distinctions between ideal and non-ideal approaches to theorizing justice along several different dimensions, showing how non-ideal approaches are needed to address normative aspects of real-world problems and to provide practical guidance. We argue that there are advantages to a transitional approach to justice focusing on manife…Read more

    Imposing options on people in poverty: The harm of a live donor organ market
    Journal of Medical Ethics 40 (3): 145-150. 2014.
    A prominent defence of a market in organs from living donors says that if we truly care about people in poverty, we should allow them to sell their organs. The argument is that if poor vendors would have voluntarily decided to sell their organs in a free market, then prohibiting them from selling makes them even worse off, at least from their own perspective, and that it would be unconscionably paternalistic to substitute our judgements for individuals' own judgements about what would be best fo…Read more

    On the Rational Impotence of Urges
    European Journal of Analytic Philosophy 10 (1): 70-75. 2014.
    Intuitively, it seems that certain basic desires, or urges, are rationally impotent, i.e., that they provide no reasons for action (a famous example is Warren Quinn's story of a man who has a brute urge to turn on every radio he sees). This intuition seems to conflict with the internalist, or Humean subjectivist, claim that our desires give us reasons. But Harry Frankfurt's well-known subjectivist account, with its distinction between first- order and higher-order desires and its concepts of ide…Read more

    Were Kant's Hypothetical Imperatives Wide-Scope Oughts?
    Australasian Journal of Philosophy 92 (4): 783-788. 2014.
    I defend the claim that Kant held a wide-scope view of hypothetical imperatives, against objections raised by Mark Schroeder [2005]. There is an important objection, now commonly known as the ‘bootstrapping’ problem, to the alternative, narrow-scope, view which Schroeder attributes to Kant. Schroeder argues that Kant has sufficient resources to reply to the bootstrapping problem, and claims that this leaves us with no good reason to attribute to Kant the wide-scope view. I show that Schroeder's …Read more

    Organ markets and harms: A reply to Dworkin, Radcliffe Richards and Walsh
    Journal of Medical Ethics 40 (3): 155-156. 2014.
    In my recent article in the Journal of Medical Ethics, I attacked the Laissez Choisir Argument in defence of letting individuals choose whether to sell kidneys or other organs as living donors, and I argued that such transactions should generally remain prohibited.1 The LC Argument arises as a response to a prohibitionist claim that I endorse: organ sales should be banned to protect potential poverty-stricken vendors, even if a free market could provide great benefits to potential organ recipien…Read more

    How to Reverse the Organ Shortage
    Journal of Applied Philosophy 29 (4): 344-358. 2012.
    Thousands of lives are lost each year because of a lack of organs available for transplant, but currently, in the UK and many other countries, organs cannot be taken from a deceased donor without explicit consent from the donor or his or her relatives. Switching to an ‘opt‐out’ system for organ donation could substantially increase the supply of organs, and save many lives. However, it has been argued in some quarters that there are serious ethical objections to an opt‐out policy, and that it wo…Read more
