    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

    Philosophia Christi 3 (1): 284-286. 2001.
    This is a review of Robert Merrihew Adams's book Finite and Infinite Goods (Oxford UP 1999), which provides an impressive theistic axiological and ethical theory.

    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

    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.

    This paper concerns some claims by Hume in the Enquiry Concerning Human Understanding Section X Part II -- specifically, what he says on pp.121-122 of Selby-Bigge's edition. Today (in September 2021) I have re-read the paper for the first time in decades. I cannot recommend that anyone else now read it: my argument was seriously defective. I still think, however, that its conclusion is correct, and accordingly may eventually write a new paper on the topic.

    God, the Best, and Evil
    Oxford University Press. 2008.
    God, the Best, and Evil is an original treatment of notable problems about God and his actions towards human beings. Three main topics are investigated in detail. First, if God exists, is God in some sense necessarily a value-maximizer? Second, Does a serious difficulty for the existence of God arise from the apparent fact that if God exists then God could have actualized a better possible world than this one? Thirdly are there strong objections top the existence of God based on evil? In the co…Read more

    Identity and spatio-temporal continuity
    Australasian Journal of Philosophy 50 (2): 184-189. 1972.
    This article considers recent arguments against the proposition that one and the same object cannot go out of existence and then come into existence again (so that, e.g., teleportation would involve change of identity.). It argues that these arguments can be evaded by adopting a four-dimensional ontology, according to which human beings, trees, etc., have temporal as well as spatial parts.
