    Can God replace the actual world by a better one?
    Philosophical Papers 20 (3): 183-192. 1991.
    This paper has been superseded by Chapter 5 (especially section 5.4) of my book "God, the Best, and Evil" (OUP 2008). The chapter, like the journal article, is concerned with objections to the existence of God that are based on the apparent improvability of the world, yet are independent of the problem of evil.

    Perception and corrigibility

    This paper, the first of mine to be published, criticizes some arguments against the logical (i.e., metaphysical) possibility that there is incorrigible knoweledge of the external world.

    Locke and the relativisation of identity
    Philosophical Studies 27 (6). 1975.

A11 aihrmativc answer will have drastic repercussions 011 0ne’s account of identity and on one’s quantification theory. For suppose that the expression ‘x is the same F as y’ can be understood as ‘x is an F and y is an F and x is identical with y’, and that ‘x is not the same G as y’ can be understood as ‘it is not the case that x is a G and y is a G and x is identical with y’.

    The Prospects for the Free Will Defence
    Faith and Philosophy 27 (2): 142-152. 2010.
    The main conclusion of the paper is that the prospects for a successful Free Will Defence employing Alvin Plantinga’s basic strategy are poor.

    Similarity, continuity and survival
    Australasian Journal of Philosophy 53 (1). 1975.
    The paper defends the claim that it is metaphysically possible that continuants of at least some kinds can have life-histories that incorporate temporal gaps -- i.e., the continuants can go out of existence and then come into existence again. Opponents of this view have included Graham Nerlich and Bernard Williams, whose writings I discuss.i

    Hume on testimony to the miraculous
    Sophia 11 (1): 20-25. 1972.
    Hume, in the Enquiry Section X Part 1, claims that ’all probability supposes an opposition of experiments and observations, where one side is found to overbalance the other and to produce a degree of evidence proportioned to the superiority’. He concludes that in assessing miracle-claims one should weigh the historical testimony supporting the miracle against the testimony supporting the regularity to which it is an exception. I argue that both his premise and his conclusion are false.

    God and Infinite Hierarchies of Creatable Worlds
    Faith and Philosophy 23 (4): 460-476. 2006.
    This paper has been superseded by chapter 3 of my book "God, the Best, and Evil" (OUP 2008). The chapter concerns God's choices in cases in which God has infinitely many better and better options.

    Swinburne on the Simplicity of Theism
    European Journal for Philosophy of Religion 3 (2). 2011.
    This paper argues that (1) Richard Swinburne’s general account of the simplicity of empirical hypotheses fails because it involves a deeply problematic notion of postulating a property, while there is a wide range of hypotheses where the assessment of simplicity rests entirely on the number and kinds of postulated properties, (2) Swinburne’s main argument in ’The Christian God’ for the simplicity of theism, the one based on considerations about pure limitless intentional power, is significantly …Read more

    Eyeballing evil: Some epistemic principles
    Philosophical Papers 25 (2): 127-137. 1996.
    The version uploaded to this site is a late draft. The paper arises both from William L. Rowe's classic 1979 discussion of the problem of evil, argues that there exist instances of intense suffering which an omnipotent, omniscient being could have prevented without thereby losing some greater good or permitting some evil equally bad or worse, and also from Steven Wykstra's response, in the course of which he argues for the following Condition of Reasonable Epistemic Access (CORNEA): "On the basi…Read more

    Reply to Oppy on God, the Best and Evil
    Sophia 50 (1): 211-219. 2011.
    My reply corrects one misstatement in Oppy’s summary of my book, abandons a footnote in the light of one of Oppy’s criticisms, and argues that Oppy’s other criticisms do not succeed in showing either that my claims are mistaken or that the arguments by which I supported them are defective

    Popper on induction and independence
    Philosophy of Science 44 (2): 326-331. 1977.
    Karl Popper, in "The Logic of Scientific Discovery" Section *vii, argues that if you find that some objecta a,b, c ... have a specific property P, then this discovery by itself does not increase the probability that some other object also has P. He concludes that there can be no effective principle of induction. My paper disproves Popper's claim, using very elementary considerations..

    Miracles and principles of relative likelihood
    International Journal for Philosophy of Religion 18 (3). 1985.
    I EXAMINE VARIOUS SUGGESTED PRINCIPLES FOR WEIGHING TESTIMONY TO PAST EVENTS AND IDENTIFY ONE WHICH SEEMS TO BE BOTH TRUE AND ROUGHLY IN THE SPIRIT OF DAVID HUME’S ESSAY. I ARGUE THAT HUME FAILS TO PROVIDE GOOD REASONS FOR SAYING THAT THIS PRINCIPLE, WHEN APPLIED TO REPORTS OF MIRACLES PURPORTING TO SUPPORT RELIGIOUS BELIEFS, WILL ALWAYS LEAD US TO REJECT THE OCCURRENCE OF THE MIRACLE

    Wiggins' defence of essentialism
    Southern Journal of Philosophy 13 (4): 459-469. 1975.
    This paper is a critique of David Wiggins's treatment of essentialism in his book Identity and Spatio-Temporal Continuity (Blackwell 1967). I argue in detail that he has not provided an adequate account either of the concept of a sortal term or of the concept of a substance-concept, even though both concepts play important roles in his case for essentialism. I also discuss Wiggins's views on how substance-concepts are related to judgments of identity through time.

    Review of "God and Necessity" by Brian Leftow (review)
    Philosophia Christi 3 (1): 284-286. 2001.
    The review is a concise summary of the main line of argument Leftow advances for his highly original, detailed theistic account of the metaphysical foundations of broadly logical necessity.

    In tyhis book chapterI provides concise overviews of Richard Swinburne's views on topics in natural theology and also in distinctively Christian philosophical theology; changes in his views are identified. I explain Swinburne's positive, cumulative case for the existence of God, and his discussion of objections to God based on evil, and then move on to outline his views on A tonement, Revelation, the Trinity, and the Incarnation. I then sketch his case for the truth of Christianity, and and his…Read more

    Hume, Probability, Lotteries and Miracles
    Hume Studies 16 (1): 67-74. 1990.
    Hume’s main argument against rational belief in miracles might seem to rule out rational belief in other antecedently improbable occurrences as well--for example, a certain person’s having won the lottery. Dorothy Coleman has recently defended Hume against the lottery counterexample, invoking Hume’s distinction between probability of chances and probability of causes. I argue that Coleman’s defence fails

    God and the Best
    Faith and Philosophy 13 (3): 311-328. 1996.
    The paper reaches two main conclusions: Firstly, even if there are one or more possible worlds than which there are none better, God cannot actualise any of them. Secondly, if there are possible worlds which God can actualise, and than which God can actualise none better, then God must actualise one of them. The paper is neutral between compatibilist and libertarian views of creaturely freedom. The paper's main ideas have been used, with modifications, in my book "God, the Best, and Evil" (OUP 2…Read more

    The Classical and Maximin Versions of the Two-Envelope Paradox
    Australasian Journal of Logic 2 30-43. 2004.
    The Two-Envelope Paradox is classically presented as a problem in decision theory that turns on the use of probabilities in calculating expected utilities. I formulate a Maximin Version of the paradox, one that is decision-theoretic but omits considerations of probability. I investigate the source of the error in this new argument, and apply the insights thereby gained to the analysis of the classical version.
