    How much are we morally required to do to aid others? After articulating some of the main contributions to this debate, I defend the position that we are sometimes morally permitted to spend our time and resources satisfying our own interests and needs rather than using them to aid others who are in desperate need. I argue that the duty to aid the needy should not always take priority over every other end we have. Whatever else we value, we most highly value the ability and opportunity to live o…Read more

    A sufficiently political orthodox conception of human rights
    Journal of Global Ethics 10 (2): 167-182. 2014.
    The traditional conception of human rights, or the orthodox conception (OC), has, over the last few years, been vigorously challenged by the political conception (PC) of human rights.

The second is to argue that the OC has the resources to respond to the PC's most challenging criticism; namel…Read more

    Equality, sufficiency, and the state
    Dialogue 46 (2): 311-334. 2007.
    In this article, I support the liberal claim that the state’s fundamental responsibility is to ensure that persons are able to interact as equals, that is, on the basis of equal freedom. That persons must be treated as responsible agents leads to an obligation on the part of the state to ensure that its citizens have the necessary conditions (and resources) for responsible agency. I further suggest that this conception of equality and the requirement for responsible agency is the right measure t…Read more
  • Rescue and the Duty to Aid
    Dissertation, University of Toronto (Canada). 2001.
    It is a commonly held view that we ought to help others when they are in peril or in need, at least when we can do so at little cost to ourselves. This means that we have a duty to aid the child drowning in the pool of water in front of us and that we also have a duty to aid hungry and needy people in distant places. I agree with this view, but I show that it does not follow that the situation of the drowning child and the situation of the needy person bind us in the same way. ;Rescue and the Du…Read more
