    Ontological disproof of God's existence
    Australasian Journal of Philosophy 70 (2). 1992.
    An initial reading of Hume's Principle is that no necessary truth can be denied without contradiction, whereas all existential propositions can. Therefore it is self-contradictory to say,that any existential claim is necessarily true, since it follows that this claim both can and cannot be denied without self-contradiction. Thus any claim of the form 'X necessarily exists' is a self-contradiction, even if X is God

    Moore’s Paradoxes and Iterated Belief
    Journal of Philosophical Research 32 145-168. 2007.
    I give an account of the absurdity of Moorean beliefs of the omissive form(om) p and I don’t believe that p,and the commissive form(com) p and I believe that not-p,from which I extract a definition of Moorean absurdity. I then argue for an account of the absurdity of Moorean assertion. After neutralizing two objections to my whole account, I show that Roy Sorensen’s own account of the absurdity of his ‘iterated cases’(om1) p and I don’t believe that I believe that p,and(com1) p and I believe tha…Read more

    In 2004, I explained the absurdity of Moore-paradoxical belief via the syllogism (Williams 2004): (1) All circumstances that justify me in believing that p are circumstances that tend to make me believe that p. (2) All circumstances that tend to make me believe that p are circumstances that justify me in believing that I believe that p. (3) All circumstances that justify me in believing that p are circumstances that justify me in believing that I believe that p. I then took (3) to mean (EP) What…Read more

    A central feature of Confucianism is the doctrine that an adult child has, for want of a better word, the ‘duty’ to care for his elderly parents1. Whether this doctrine should be framed in terms of an ethic of duties as opposed to an ethic of virtues is a vexed question. It might be argued that the doctrine is best framed in terms of the behaviour and dispositions appropriate to an agent who is, within the Confucian moral vision, good. Nonetheless, in both popular discourse and in much the secon…Read more

    Placebo-trials on HIV-infected pregnant women in developing countries like Thailand and Uganda have provoked recent controversy. Such experiments aim to find a treatment that will cut the rate of vertical transmission more efficiently than existing treatments like zidovudine. This scenario is first stated as generally as possible, before three ethical principles found in the Belmont Report, itself a sharpening of the Helsinki Declaration, are stated. These three principles are the Principle of U…Read more
