    Leibniz, Locke and I
    Cogito 13 (3): 181-187. 1999.
    In his New Essays on Human Understanding, Leibniz presents a sharp attack on Locke's theory of personal identity, Matching Locke's thought-experiments with those of his own, Leibniz seeks to show that our identity cannot rest on matters of consciousness alone-being the same person is rather a matter of the continued existence of an immaterial substance. I draw attention to some contemporary thinkers who-while eschewing the immaterial substances-are sympathetic to the kind of argument Leibniz off…Read more

    Back to the self and the future
    South African Journal of Philosophy 17 (3): 211-225. 1998.
    The thought-experiment presented by Bernard Williams in 'The self and the future' continues to draw the attention of writers in the debate about personal identity. While few of them agree on what implications it has for the debate, almost all agree that those implications are significant ones. Some have even claimed that it has consequences not only for personal identity, but also concerning the viability of thought-experiment as a method. This paper surveys what these consequences might be at b…Read more

    Counterfactuals and the law
    South African Journal of Philosophy 12 (3). 1993.
    This article is concerned with the place counterfactual reasoning occupies in South African law, and how philosophy might be able to help the law. I point out some of the more important and unavoidable uses of counterfactual reasoning in our law. Following this I make some suggestions as to how philosophy, and especially informal logic, can be of help to the law. Finally, I make some suggestions as to how the law in turn can help philosophy.

    Should we tolerate people who split?
    Southern Journal of Philosophy 30 (1): 1-17. 1992.
    Thought-experiments in which one person divides into two have been important in the literature on personal identity. I consider three influential arguments which aim to undermine the force of these thought-experiments – arguments from David Wiggins, Patricia Kitcher and Kathleen Wilkes. I argue that all three fail, leaving us to face the consequences of splitting, whatever those may be.

    Intuitionism, Constructive Interpretation, and Cricket
    Philosophical Papers 37 (2): 319-331. 2008.
    This paper is a re-reading of Colin Radford's paper 'The Umpire's Dilemma', published in Analysis in 1985. It argues that Radford's dilemma has been unjustly ignored and has interesting (and problematic) implications for both intuitionism and Ronald Dworkin's constructive interpretationist jurisprudence.

    Our Identity, Responsibility and Biology
    Philosophical Papers 3-14. 2004.
    Eric Olson argues in The Human Animal that thought-experiments involving body-swapping do not in the end offer any support to psychological continuity theories, nor do they pose any threat to his Biological View. I argue that he is mistaken in at least the second claim.
