    On the conditional analysis of phenomenal concepts
    Philosophical Studies 131 (3): 777-778. 2006.
    Zombies make trouble for physicalism. Intuitively, they seem conceivable, and many take this to support their metaphysical possibility – a result that, most agree, would refute physicalism. John Hawthorne (2002) [Philosophical Studies 109, 17–52] and David Braddon-Mitchell (2003) [The Journal of Philosophy 100, 111–135] have developed a novel response to this argument: phenomenal concepts have a conditional structure – they refer to non-physical states if such states exist and otherwise to physi…Read more

    A limited defense of the knowledge argument
    Philosophical Studies 90 (1): 35-56. 1998.

    The hard problem of consciousness
    In Patrick Wilken, Timothy J. Bayne & Axel Cleeremans (eds.), The Oxford Companion to Consciousness, Oxford University Press. 2009.
    As I type these words, cognitive systems in my brain engage in visual and auditory information processing. This processing is accompanied by subjective states of consciousness, such as the auditory experience of hearing the tap-tap-tap of the keyboard and the visual experience of seeing the letters appear on the screen. How does the brain's activity generate such experiences? Why should it be accompanied by conscious experience in the first place? This is the hard problem of consciousness.
