    Selves and Moral Units
    Pacific Philosophical Quarterly 80 (4): 391-419. 1999.
    Derek Parfit claims that, at certain times and places, the metaphysical units he labels *'selves" may be thought of as the morally significant units (I.e., the objects of moral concern) for such things as resource distribution, moral responsibility, commitments, etc. But his concept of the self is problematic in important respects, and it remains unclear just why and how this entity should count as a moral unit in the first place. In developing a view I call *'Moderate Reductionism," I attempt t…Read more

    The Stony Metaphysical Heart of Animalism
    In Stephan Blatti & Paul F. Snowdon (eds.), Animalism: New Essays on Persons, Animals, and Identity, Oxford University Press Uk. pp. 303-328. 2016.
    Animalism—the view that the identity across time of individuals like us consists in the persistence of our animal organisms—does poorly at accounting for our identity-related practical concerns. The reason is straightforward: whereas our practical concerns seem to track the identity of psychological creatures—persons—animalism focuses on the identity of human organisms who are not essentially persons. This lack of fit between our practical concerns and animalism has been taken to reduce animal…Read more

    Responsibility and disability
    Metaphilosophy 40 (3-4): 438-461. 2009.
    This essay explores the boundaries of the moral community—the collection of agents eligible for moral responsibility—by focusing on those just inside it and those just outside it. In particular, it contrasts mild mental retardation with psychopathy, specifically among adults. For those who work with and know them, adults with mild mental retardation are thought to be obvious members of the moral community (albeit not full-fledged members). For those who work with and theorize about adult psychop…Read more

    Personal identity and practical concerns
    Mind 116 (462): 317-357. 2007.
    Many philosophers have taken there to be an important relation between personal identity and several of our practical concerns (among them moral responsibility, compensation, and self-concern). I articulate four natural methodological assumptions made by those wanting to construct a theory of the relation between identity and practical concerns, and I point out powerful objections to each assumption, objections constituting serious methodological obstacles to the overall project. I then attempt …Read more

    Recently T. M. Scanlon and others have advanced an ostensibly comprehensive theory of moral responsibility—a theory of both being responsible and being held responsible—that best accounts for our moral practices. I argue that both aspects of the Scanlonian theory fail this test. A truly comprehensive theory must incorporate and explain three distinct conceptions of responsibility—attributability, answerability, and accountability—and the Scanlonian view conflates the first two and ignores the im…Read more
