    Prediction and Providence
    In Lara Buchak, Dean W. Zimmerman & Philip Swenson (eds.), Oxford Studies in Philosophy of Religion Volume 9, Oxford University Press. pp. 225-235. 2019.
    Chapter 12 responds to Michael Almeida’s chapter in this volume, “Unrestricted Actualization and Perfect Worlds: A Reply to Langtry.” It concludes that Langtry’s main claims in his own chapter in this volume, “Unrestricted Actualization and Divine Providence” are undamaged by Almeida’s remarks.

    Unrestricted Actualization and Divine Providence
    In Lara Buchak, Dean W. Zimmerman & Philip Swenson (eds.), Oxford Studies in Philosophy of Religion Volume 9, Oxford University Press. pp. 195-212. 2019.
    Chapter 10 critiques Michael Almeida’s case for God’s having providential options involving unrestricted actualization. Almeida holds that as well as strong actualization and weak actualization, there are two other approaches to world-actualization open to God: restricted actualization and unrestricted actualization. The latter consists in God’s bringing about a finite person’s freely performing an undetermined action _merely by God’s predicting it_. The alleged availability of unrestricted actu…Read more

    Evaluating a New Logical Argument From Evil
    Faith and Philosophy 38 (2): 229-244. 2021.
    J. L. Schellenberg, in “A New Logical Problem of Evil,” published in The Blackwell Companion to the Problem of Evil, argues that (if God exists) God has, of necessity, a disappreciation of evil, operating at a metalevel in such a way as to give God a non-defeasible reason to rule out actualizing a world containing evil. He also argues that since God’s motive in creating the world is to share with finite beings the good that God experiences prior to creation, which is good without evil, it follow…Read more

    God, Horrors, and Our Deepest Good
    Faith and Philosophy 37 (1): 77-95. 2020.
    J.L. Schellenberg argues that since God, if God exists, possesses both full knowledge by acquaintance of horrific suffering and also infinite compassion, the occurrence of horrific suffering is metaphysically incompatible with the existence of God. In this paper I begin by raising doubts about Schellenberg’s assumptions about divine knowledge by acquaintance and infinite compassion. I then focus on Schellenberg’s claim that necessarily, if God exists and the deepest good of finite persons is uns…Read more

    Prediction and Providence: Rejoinder to Almeida's Reply
    In L. Kvanvig Jonathan (ed.), Oxford Studies in Philosophy of Religion, Oxford University Press. pp. 225-235. 2013.
    This paper is a rejoinder to Michael Almeida's reply to my chapter "Unrestricted Actualization and Divine Providence" in Oxford Studies in Philosophy of Religion Volume 9 (where his reply also appears).
  • Unrestricted Actualization and Divine Providence
    Oxford Studies in Philosophy of Religion 9 195-212. 2019.
    Michael Almeida, in his book "Freedom, God, and Worlds" (OUP 2012) argues that (C) Necessarily, God has available an infallible method, Unrestricted Actualization, by which God can bring about whatever undetermined events God chooses, except those which it is metaphysically or accidentally necessary that God does not bring about. I argue that we have no reason to believe either of the two premises of Almeida's main argument for (C).

    Rightmaking and Wrongmaking Properties, Evil, and Theism
    In L. Kvanvig Jonathan (ed.), Oxford Studies in Philosophy of Religion, Oxford University Press. pp. 177-202. 2013.
    Michael Tooley, in Plantinga & Tooley, "Knowledge of God" (Blackwell 2008) argues that, in the absence of strong evidence in favour of the existence of God, the logical probability of God's existence is extremely low. His argument focusses on rightmaking and wrongmaking properties of divine actions, and employs Carnap's inductive logic to reach his conclusion. I argue that Tooley's argument's conceptual foundations are problematic, and that his application of Carnap's inductive logic is flawed. …Read more

    The ethics of shareholding
    Journal of Business Ethics 37 (2). 2002.
    The copy provided on ths site is a late draft. It provides a philosophical argument for the view that by and large it is morally wrong to buy shares in a company that is behaving badly unless you (if necessary acting together with others) are able and willing to prevent the misbehaviour. A key lemma in my argument concerns a chain of authorisation from the shareholders to the company's board to the CEO -- one in virtue of which shareholders are ultimately responsible for major patterns of wrongd…Read more

    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

    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

    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

    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.

    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

    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.

    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
