    A Challenge for Soft Line Replies to Manipulation Cases
    Philosophia 38 (3): 555-568. 2010.
    Cases involving certain kinds of manipulation seem to challenge compatibilism about responsibility-grounding free will. To deal with such cases many compatibilists give what has become known as a ‘soft line’ reply. In this paper I present a challenge to the soft line reply. I argue that any relevant case involving manipulation—and to which a compatibilist might wish to give a soft line reply—can be transformed into one supporting a degree of moral responsibility through the addition of l…Read more

    A Moral Argument for Substance Dualism
    Journal of the American Philosophical Association (1): 21--35. 2016.
    This paper presents a moral argument in support of the view that the mind is a nonphysical object. It is intuitively obvious that we, the bearers of conscious experiences, have an inherent value that is not reducible to the value of our conscious experiences. It remains intuitively obvious that we have inherent value even when we represent ourselves to have no physical bodies whatsoever. Given certain assumptions about morality and moral intuitions, this implies that the bearers of conscious exp…Read more

    Frankfurt-Style Cases and Improbable Alternative Possibilities
    Philosophical Studies 130 (2): 399-406. 2006.
    It has been argued that a successful counterexample to the principle of alternative possibilities must rule out any possibility of the agent making an alternative decision right up to the moment of choice. This paper challenges that assumption. Distinguishing between an ability and an opportunity, this paper presents a Frankfurt-style case in which there is an alternative possibility, but one it is highly improbable that the agent will access. In such a case the agent has only the opportunity, n…Read more

    The principle of avoidable blame
    Ethic@ - An International Journal for Moral Philosophy 3 (1): 37-46. 2004.
    Many now accept that Frankfurt-style cases refute the principle of alternative possibilities (PAP). But, in this paper I argue that even if Frankfurt-style cases refute PAP they do not refute a related principle: the principle of avoidable blame (PAB). My argument develops from the observation that an agent in a Frankfurt-style case can be aware of the nature of their situation without this undermining their moral responsibility. I then argue that PAB captures all that is important about PAP suc…Read more

    Virtually everyone takes the moral supervenience thesis to be a basic conceptual truth about morality. As a result, if a metaethical theory has difficulties respecting or adequately explaining the supervenience relationship it is deemed to be in big trouble. However, the moral supervenience thesis is a not a conceptual truth (though it may be true) and as such it is not a problem if a metaethical theory cannot respect or explain it.

    A God exists
    Think 15 (43): 51-63. 2016.
    I argue that normative reasons are powerful evidence that a god exists. Normative reasons are presupposed by all intellectual inquiry, yet it appears there is only one thing they could credibly be: the favourings a god is having of us doing and believing things. I anticipate some possible objections and show them to be confused or dogmatic.

    Libertarian Free Will and the Erosion Argument
    Polish Journal of Philosophy 1 (2): 61-75. 2007.
    Libertarians make indeterminism a requirement of free will. But many argue that indeterminism is destructive of free will because it reduces an agent’s control. This paper argues that such concerns are misguided. Indeterminism, at least as it is located by plausible Libertarian views, poses no threat to an agent’s control, nor does it pose any other kind of threat.

    Frankfurt-Style Cases and the Significance of the First Impression
    American Philosophical Quarterly 46 (3): 213-223. 2009.
    The claim that moral responsibility requires relevant alternative possibilities is encapsulated by the following principle: PAP: A person is morally responsible for what he has done only if he could have done otherwise. In 1969 Harry Frankfurt devised what purported to be a counterexample to PAP: Suppose someone, Black, let us say, wants Jones to perform a certain action. Black is prepared to go to considerable lengths to get his way, but he prefers to avoid showing his hand unnecessarily. So he…Read more
