    I argue for the following four theses: (1) The Dread Thesis: human beings should fear having false religious beliefs concerning some religious doctrines; (2) The Radical Uncertainty Thesis: we, namely most human beings in our culture at our time, are in a situation where we have to commit ourselves on the truth or falsity of some propositions of ultimate importance; (3) The Radical Choice Thesis: considerations of expected loss or gain do not always provide guidance as to how to commit ourselves…Read more

    The nature of number
    Philosophical Papers 16 (3): 165-186. 1987.
    The article develops and extends the theory of Glenn Kessler (Frege, Mill and the foundations of arithmetic, Journal of Philosophy 77, 1980) that a (cardinal) number is a relation between a heap and a unit-making property that structures the heap. For example, the relation between some swan body mass and "being a swan on the lake" could be 4.

    Towards an epistemology of religious traditions
    Sophia 38 (1): 25-40. 1999.
    Starting from the acceptance of the Egalitarian Principle I exhibited a version which I considered too lax (BEP) and one I considered too strict (NEP), arriving at a version (MEP) which allows that there can be tolerance-limiting reasons for adhering to traditions but only if they are based on unreasoned knowledge claims. In fact, I hold that the situation most of us find ourselves in restricts such claims on religious topics to very general ones. Hence the choice between NEP and MEP is not sign…Read more

    Several authors, including Stephen Law in this journal, have argued that the case for an evil God is (about) as strong as for a good God. In this article I take up the challenge on behalf of theists who, like Richard Swinburne, argue for an agent of unrestricted power and knowledge as the ultimate explanation of all contingent truths. I shall argue that an evil God is much less probable than a good one. I do so by (1) distinguishing the analogical predication of 'good' or 'evil' of God from the …Read more

    Nonclassical Mereology and Its Application to Sets
    Notre Dame Journal of Formal Logic 43 (2): 79-94. 2002.
    Part One of this paper is a case against classical mereology and for Heyting mereology. This case proceeds by first undermining the appeal of classical mereology and then showing how it fails to cohere with our intuitions about a measure of quantity. Part Two shows how Heyting mereology provides an account of sets and classes without resort to any nonmereological primitive

    Chris Heathwood requires the sentence 'Caesar was conscious when he crossed the Rubicon' to be made true in much the same way as 'Caesar was wet when he crossed the Rubicon'. Yet because the Growing Block theorist is committed to the zombiedom of the past,the former is not made true by past objects, although the latter is. Heathwood demands a uniform account of the grounding of truths and he will be given a uniform account. But we should exercise care in deciding just what sort of uniformity is …Read more

    In this paper, I present a piece of natural theology, whose pro tanto conclusion is the existence of god-the-artist, that is a lower case “g” god, a creator who creates for the sake of beauty, but who is not worthy of worship, a god who can be admired but should not be loved. I then consider some only partially successful responses to this dismal conclusion. Finally, I show to reconcile the idea of a god motivated by love of beauty with the religious tradition of an upper case “G” God, who is no…Read more

    In this book Timothy O’Connor combines an investigation of modal epistemology with a fresh look at the traditional contingency version of the cosmological argument. The connection between the two parts is that he defends the practice of hypothesizing necessities for explanatory purposes, resisting those accounts that link possibility too closely to conceivability. This provides the context in which he asks the existence question, ‘Why do the particular contingent objects there are exist and unde…Read more

    The personal pantheist conception of God
    In Andrei Buckareff & Yujin Nagasawa (eds.), Alternative Concepts of God: Essays on the Metaphysics of the Divine, Oxford University Press. pp. 21-40. 2016.
    This chapter is a case for the pantheist conception considered as a species of theism, rather than a rival to it. The starting point, the premise of the argument, is properly anthropomorphic metaphysics, which I propose as a rival to scientific naturalism; I begin, then, by stating my version of pantheism, by expounding PAM, and by sketching my argument

    The mereology of structural universals
    Logic and Logical Philosophy 25 (3): 259-283. 2016.
    This paper explores the mereology of structural universals, using the structural richness of a non-classical mereology without unique fusions. The paper focuses on a problem posed by David Lewis, who using the example of methane, and assuming classical mereology, argues against any purely mereological theory of structural universals. The problem is that being a methane molecule would have to contain being a hydrogen atom four times over, but mereology does not have the concept of the same part o…Read more

    Occam’s Razor and Possible Worlds
    The Monist 65 (4): 456-464. 1982.
    In this paper I argue against Realism about Possible Worlds by showing how it leads to a counter-intuitive scepticism about the rationality of Occam’s razor. This can be thought of as a transcendental argument from Logic to Metaphysics. It should be contrasted with a straightforward application of Logic to Metaphysics, as when we apply Occam’s razor to reject a category of entities which we judge to be redundant.

    Grit or Gunk: Implications of the Banach-Tarski Paradox
    The Monist 87 (3): 351-370. 2004.
    This paper concerns the structure of any spatially extended things, including regions of space or spacetime. I shall use intuitions about the quantity of extended things to argue for a dichotomy: either a given finite extended thing is point-free gunk, that is, it has no points as parts, or it is made of grit, that is there are only finitely many points.

    9 God and Perfect Beauty
    In Mirosław Szatkowski (ed.), Ontology of Divinity, De Gruyter. pp. 195-220. 2024.
    That God is of great beauty is religiously significant as a component of the widespread hope of a blessed experience in this or the next life. This motivates the project of formulating the strongest coherent thesis of divine beauty. This chapter has two parts. In Section 9.1 I argue for the incoherence of Perfect Divine Beauty. The natural reaction to this incoherence is to replace the idea of perfection, but in a way that coheres with the theists’ religious tradition. I explore a range of such …Read more
