    Response to Buckle
    Journal of Medical Ethics 15 (3): 166-166. 1989.
    This is a brief response to Stephen Buckle's paper 'Biological Processes and Moral Events', Journal of Medical Ethics 14 (1988): 144-7, in which Buckle argues that the continuity of early human development does not preclude there being 'morally significant' events, such as syngamy, that set boundaries for the permissibility of human embryo experimentation. I reply to Buckle that the very continuity at issue does indeed preclude the existence of such 'morally significant' events, and that the Aus…Read more

    Further clarity on cooperation and morality
    Journal of Medical Ethics 43 (4): 192-200. 2017.
    I explore the increasingly important issue of cooperation in immoral actions, particularly in connection with healthcare. Conscientious objection, especially as pertains to religious freedom in healthcare, has become a pressing issue in the light of the US Supreme Court judgement inHobby Lobby. Section ‘Moral evaluation using the basic principles of cooperation’ outlines a theory of cooperation inspired by Catholic moral theologians such as those cited by the court. The theory has independent pl…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

    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

    You might be wondering what an article 0n animal rights is doing in a journal devoted to the defence of human life. It turns out that the connections are closer than you may think. Grasping them is crucial to a proper understanding of just why innocent human life must be defended, of why the killing of even the tiniest, youngest member of the human species is an unspeakable crime. For it is by analysing the issue of whether animals have rights that we come to see the core differences between hum…Read more

    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

    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

    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.

    Morality, Religion, and Cosmic Justice
    Philosophical Investigations 34 (2): 189-213. 2011.
    There is a famous saying, whose origin is uncertain, that no good deed goes unpunished. Although not cited by him, this was no doubt the thought that inspired George Mavrodes’s (1986) well-known article “Religion and the Queerness of Morality.” In it he argued that although not logically incoherent, a certain sort of world in which moral obligations existed would be “absurd . . . a crazy world” (Mavrodes 1986, 581). The world he had in mind was what he called “Russellian,” after a notorious pass…Read more

    The Metaphysical Status of the Embryo: Some Arguments Revisited
    Journal of Applied Philosophy 25 (4): 263-276. 2008.
    abstract This paper re‐examines some well‐known and commonly accepted arguments for the non‐individuality of the embryo, due mainly to the work of John Harris. The first concerns the alleged non‐differentiation of the embryoblast from the trophoblast. The second concerns monozygotic twinning and the relevance of the primitive streak. The third concerns the totipotency of the cells of the early embryo. I argue that on a proper analysis of both the empirical facts of embryological development, and…Read more

    l. ln `“Time, Successive Addition. and Kn/uni Cosmological Arguments," Graham Oppy accuses supporters ofthe KCA of being committed to a strict Hnitist metaphysics. lfthis is supposed to mean that we deny continua in nature, that is quite wrong. All it means is that we deny the existence of actual intinities. ln fact, Oppy protesses not to be tackling that question but throughout his paper he suggests or implies that the KCA falls down on this score.

    The doctrine of double effect
    In Timothy O'Connor & Constantine Sandis (eds.), A Companion to the Philosophy of Action, Wiley-blackwell. pp. 324-330. 2010.
    Few moral theorists would disagree that the fundamental principle of morality – perhaps of practical rationality itself – is “ Do good and avoid evil. ” Yet along with such an uncontroversial principle comes a major question: Can you fulfi l both halves satisfactorily across your life as a moral agent? We all have opportunities to perform acts that do good with no accompanying evil, but these are not as common as we might think. We can avoid evil by doing nothing, but doing nothing implies doing…Read more

    Human Values: New Essays on Ethics and Natural Law. 1st Edition (edited book)
    with T. Chappell
    Palgrave-Macmillan. 2004.
    In recent decades, the revival of natural law theory in modern moral philosophy has been an exciting and important development. Human Values brings together an international group of moral philosophers who in various respects share the aims and ideals of natural law ethics. In their diverse ways, these authors make distinctive and original contributions to the continuing project of developing natural law ethics as a comprehensive treatment of modern ethical theory and practice.

    Response to commentaries: ‘Further clarity on cooperation and morality’
    Journal of Medical Ethics 43 (4): 204-205. 2017.
    I am grateful to Dr Stammers and Professor Vacek for their thoughtful commentaries on my paper.1 I will take their points one by one, though in no special order. Given the space available, I will confine myself to their most important remarks. Dr Stammers accuses me of aligning religion and conscience too closely.2 I agree with him that conscience is broader than religion and that the issue of conscientious objection should be framed so as to handle wholly non-religious ethical objections. I wro…Read more

    Finality revived: powers and intentionality
    Synthese 194 (7): 2387-2425. 2017.
    Proponents of physical intentionality argue that the classic hallmarks of intentionality highlighted by Brentano are also found in purely physical powers. Critics worry that this idea is metaphysically obscure at best, and at worst leads to panpsychism or animism. I examine the debate in detail, finding both confusion and illumination in the physical intentionalist thesis. Analysing a number of the canonical features of intentionality, I show that they all point to one overarching phenomenon of …Read more

    On the cardinality of the cardinal virtues
    International Journal of Philosophical Studies 7 (3). 1999.
    This paper is a detailed study of what are traditionally called the cardinal virtues: prudence, justice, temperance and fortitude. I defend what I call the Cardinality Thesis, that the traditional four and no others are cardinal. I define cardinality in terms of three sub-theses, the first being that the cardinal virtues are jointly necessary for the possession of every other virtue, the second that each of the other virtues is a species of one of the four cardinals, and the third that many of t…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.
