    Bioethics 8 (3): 223-246. 2007.
    ABSTRACT This Paper argues that Living wills are typically nebulous and confused documents that do not effectively enable you to determine your future treatment. Worse, signing a living will can end your life in ways you never intended, long before you are either incompetent or terminally ill. This danger is compounded by the fact that those who implement living wills are often themselves dangerously confused, so that, for example, they cannot be relied upon to distinguish living wills from DNR …Read more

    What is it Like to Have an Unconscious Mental State?
    Philosophical Studies 104 (2): 197-202. 2001.
    HOST is the theory that to be conscious of a mental state is totarget it with a higher-order state (a `HOS'), either an innerperception or a higher-order thought. Some champions of HOSTmaintain that the phenomenological character of a sensory stateis induced in it by representing it with a HOS. I argue that thisthesis is vulnerable to overwhelming objections that flow largelyfrom HOST itself. In the process I answer two questions: `What isa plausible sufficient condition for a quale's belonging …Read more

    CORNEA, Scepticism and Evil
    Australasian Journal of Philosophy 89 (1): 59-70. 2011.


    The Principle of Credulity: 'It is basic to human knowledge of the world that we believe things are as they seem to be in the absence of positive evidence to the contrary' [Swinburne 1996: 133]. This underlies the Evidential Problem of Evil, which goes roughly like this: ‘There appears to be a lot of suffering, both animal and human, that does not result in an equal or greater utility. So there's probably some pointless suffering. As God's existence precludes pointless suffering, theism is impla…

    Zombies, Functionalism and Qualia
    Res Philosophica 99 (1): 91-93. 2022.
    David Chalmers maintains there is a logically possible world (Z) where we all have physically and functionally identical twins without conscious experiences. Z entails that qualia are extra-physical, hence physicalism is false. I argue that his Zombie Argument (ZA) fails on functionalist grounds. Qualia sometimes affect behavior or they never do. If they do affect behavior, they sometimes individuate functional states; hence my zombie twin cannot be functionally identical to me. To save ZA, we m…Read more

    Why there still are no people
    Philosophy and Phenomenological Research 70 (1): 174-191. 2005.
    This paper argues that there are no people. If identity isn't what matters in survival, psychological connectedness isn't what matters either. Further, fissioning cases do not support the claim that connectedness is what matters. I consider Peter Unger's view that what matters is a continuous physical realization of a core psychology. I conclude that if identity isn't what matters in survival, nothing matters. This conclusion is deployed to argue that there are no people. Objections to Eliminati…Read more

    Trumping the causal influence account of causation
    Philosophical Studies 142 (2). 2009.
    Here is a simple counterexample to David Lewis’s causal influence account of causation, one that is especially illuminating due to its connection to what Lewis himself writes: it is a variant of his trumping example.
  • Identity and Discernability
    Dissertation, University of Colorado at Boulder. 1983.
    The dissertation is composed of five papers, each of which either deals with a topic in contemporary metaphysics or uses concepts central to contemporary metaphysics as part of the machinery of its argument. Three papers deal with the problem of personal identity. In Hume on Identity: A Defense I argue that Hume, in maintaining that we are always mistaken in ascribing identity to persons, is presenting a fundamental metaphysical problem about identity through change, not trying to analyze the wa…Read more
