    Intelligibility and intensionality
    Acta Analytica 17 (1): 171-178. 2002.
    A common argumentative strategy employed by anti-reductionists involves claiming that one kind of entity cannot be identified with or reduced to a second because what can intelligibly be predicated of one cannot be predicated intelligibly of the other. For instance, it might be argued that mind and brain are not identical because it makes sense to say that minds are rational but it does not make sense to say that brains are rational. The scope and power of this kind of argument — if valid — …Read more

    Reply to Sprigge on personal and impersonal identity
    Mind 98 (January): 129-133. 1989.
    In "personal and impersonal identity" ("mind", 1988) timothy sprigge discusses reasons for a general suspicion of trans-temporal identity, and rejects what he says are the usual grounds given against the suspicion, providing instead his own reasons for rejecting it. he concludes that trans-temporal identity, including personal identity, is as genuine a case of identity as what he considers to be the paradigmatic case of identity. in this brief note i take issue with some of the basic elements of…Read more

    Temporal Parts and the Possibility of Change
    Philosophy and Phenomenological Research 69 (3): 686-708. 2004.
    Things change. If anything counts as a datum of metaphysics, that does. Change occurs in many ways: it can be accidental or substantial; essential or non-essential; intrinsic or extrinsic; subjective or objective. Changes can be physical, spatial, quantitative, qualitative, natural, artefactual, conceptual, linguistic. Events are arguably best defined as changes in an object or objects. All change is from something and into something, and hence is at least a two-term relation, involving a term f…Read more

    Who's afraid of Reverse Mereological Essentialism?
    Philosophical Studies 1-22. 2023.
    Whereas Mereological Essentialism is the thesis that the parts of an object are essential to it, Reverse Mereological Essentialism is the thesis that the whole is essential to its parts. Specifically – since RME is an Aristotelian doctrine – it is a claim not about objects in general but about substances. Here I set out and explain RME as it should be understood from the perspective of the Aristotelian-Scholastic tradition, as well as proposing a kind of master argument for believing it. A numbe…Read more

    Disembodied Communication and Religious Experience: The Online Model
    Philosophy and Technology 25 (3): 381-397. 2012.
    Abstract   The idea of disembodied communication has received widespread discussion in the context of the various kinds of online interaction. Electronic mail is probably the purest form of text-based communication where interlocutors are present in mind rather than body. I argue that this online model provides a way of understanding and defending the possibility of a certain kind of public religious experience, contra the many critics of the very coherence of genuine religious experience. I int…Read more

    Biological mistakes: what they are and what they mean for the experimental biologist
    with Jonathan Hill, Christopher Austin, Ingo Bojak, Francois Cinotti, and Jon Gibbins
    Organisms and other biological entities are mistake-prone: they get things wrong. The entities of pure physics, such as atoms and inorganic molecules, do not make mistakes: they do what they do according to physical law, with no room for error except on the part of the physicist or their theory. We set out a novel framework for understanding biology and its demarcation from physics – that of mistake-making. We distinguish biological mistakes from mere failures. We then propose a rigorous definit…Read more

    I rejoinder to Ingmar Persson’s reply to my paper ‘The Metaphysical Status of the Embryo: Some Arguments Revisited’. I argue that Persson, having conceded a large part of my case, has still misunderstood or not fully appreciated the force of that case when he claims the arguments I criticize still make it reasonable to think that a human being does not come into existence at fertilization. In addition, his appeal to the totipotency argument as remaining unscathed by my critique does not succeed.

    Should there be freedom of dissociation?
    Economic Affairs 37 (2): 167-181. 2017.
    Contemporary liberal societies are seeing increasing pressure on individuals to act against their consciences. Most of the pressure is directed at freedom of religion but it also affects ethical beliefs more generally, contrary to the recognition of freedom of religion and conscience as a basic human right. I propose that freedom of dissociation, as a corollary of freedom of association, could be a practical and ethically acceptable solution to the conscience problem. I examine freedom of associ…Read more

    The Old New Logic: Essays on the Philosophy of Fred Sommers (edited book)
    Bradford/MIT Press. 2005.
    Over the course of a career that has spanned more than fifty years, philosopher Fred Sommers has taken on the monumental task of reviving the development of Aristotelian (syllogistic) logic after it was supplanted by the predicate logic of Gottlob Frege and Bertrand Russell. The enormousness of Sommers's undertaking can be gauged by the fact that most philosophers had come to believe - as David S. Oderberg writes in his preface - that "Aristotelian logic was good but is now as good as dead." A r…Read more

    Perceptual relativism
    Philosophia 16 (1): 1-9. 1986.
    What follows axe the provisional conclusions reached in my thoughts about a frequently encountered, established argument for perceptual relativism. Rather than attempting the misleading task of dcfming in a sentence this doctrine - for it is so widely espoused by philosophers and Iaymcn alike that it deserves to bc called a doctrine — I shall instead elucidate it by thc common argu— ment for it that I wish to deal with, which Ishall call thc argument from differing perceptual apparatus, or ADP. …Read more

    The world of science was stunned, and the hopes of many people dashed, when Professor Hwang Woo Suk of Seoul National University was recently found guilty of massive scientific fraud. Until January 2006 he was considered one of the world’s leading experts in cloning and stem cell research. Yet he was found by his own university to have fabricated all of the cell lines he claimed, in articles published in Science in 2004 and 2005, to have derived from cloned human embryos. By the time he was expo…Read more

    How special is medical conscience?
    The New Bioethics 25 (3): 207-220. 2019.
    The vigorous legal and ethical debates over conscientious objection have taken place largely within the domain of health care. Is this because conscience in medicine is of a special kind, or are th...

    Coincidence under a Sortal

    As an undergraduate at the University of Melbourne in the 1980s, I recall a story that used to circulate to the effect that Australian philosophers were realists (the term prefixed by the obligatory adjective "hard-headed") because we lived in a harsh, sunlit environment where no misty meadow or morning fog obscured the objective reality of a mind-independent physical universe.

    We live in a liberal, pluralistic, largely secular society where, in theory, there is fundamental protection for freedom of conscience generally and freedom of religion in particular. There is, however, both in statute and common law, increasing pressure on religious believers and conscientious objectors to act in ways that violate their sincere, deeply held beliefs. This is particularly so in health care, where conscientious objection is coming under extreme pressure. I argue that freedom of re…Read more
