    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

    Universals as Sense‐data
    Philosophy and Phenomenological Research 71 (3): 622-631. 2007.
    This paper concerns the structure of appearances. I argue that to be appeared to in a certain way is to be aware of one or more universals. Universals therefore function like the sense‐data, once highly favoured but now out of fashion. For instance, to be appeared to treely, in a visual way, is to be aware of the complex relation, being tree‐shaped and tree‐coloured and being in front of, a relation of a kind which could be instantiated by a material object and a perceiver, which is thus instant…Read more

    In "How Do We Know It Is Now Now?" David Braddon-Mitchell (Analysis 2004) develops an objection to the thesis that the past is real but the future is not. He notes my response to this, namely that the past, although real, is lifeless and (a fortiori?) lacking in sentience. He argues, however, that this response, which I call 'the past is dead hypothesis', is not tenable if combined with 'special relativity'. My purpose in this reply is to argue that, on the contrary, 'special relativity' support…Read more

    In his recent paper in Sophia , ‘Theodicy: The Solution to the Problem of Evil, or Part of the Problem?’ Nick Trakakis endorses the position that theodicy, whether intellectually successful or not, is a morally obnoxious enterprise. My aim in this paper is to defend theodicy from this accusation. I concede that God the Creator is a moral monster by human standards and neither to be likened to a loving parent nor imitated. Nonetheless, God is morally perfect. What is abhorrent is not tough-minded…Read more

    The epistemology of religion
    Stanford Encyclopedia of Philosophy. 2008.
    Contemporary epistemology of religion may conveniently be treated as adebate over whether evidentialism applies to thebelief-component of religious faith, or whether we should insteadadopt a more permissive epistemology. Here evidentialism is theinitially plausible position that a belief is justified only if``it is proportioned to the evidence''. For example, supposea local weather forecaster has noticed that over the two hundred yearssince records began a wetter than average Winter is followed …Read more

    In this book I investigate the necessary structure of the aether the stuff that fills the whole universe. Some of my conclusions are. 1. There is an enormous variety of structures that the aether might, for all we know, have. 2. Probably the aether is point-free. 3. In that case, it should be distinguished from Space-time, which is either a fiction or a construct. 4. Even if the aether has points, we should reject the orthodoxy that all regions are grounded in points by summation. 5. If the aeth…Read more

    Vectors on Curved Space
    Dialectica 63 (4): 491-501. 2009.
    In this paper I provide an ontology for the co‐variant vectors, contra‐variant vectors and tensors that are familiar from General Relativity. This ontology is developed in response to a problem that Timothy Maudlin uses to argue against universals in the interpretation of physics. The problem is that if vector quantities are universals then there should be a way of identifying the same vector quantity at two different places, but there is no absolute identification of vector quantities, merely a…Read more

    The operator theory of instantiation
    Australasian Journal of Philosophy 84 (2). 2006.
    Armstrong holds the Supervenience Theory of instantiation, namely that the instantiation of universals by particulars supervenes upon what particulars and what universals there are, where supervenience is stipulated to be explanatory or dependent supervenience. I begin by rejecting the Supervenience Theory of instantiation. Having done so it is then tempting to take instantiation as primitive. This has, however, an awkward consequence, undermining one of the main advantages universals have over …Read more

    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

    General Facts, Physical Necessity, and the Metaphysics of Time
    Oxford Studies in Metaphysics 2 137-154. 2006.
    In this chapter I assume that we accept, perhaps reluctantly, general facts, that is states of affairs corresponding to universal generalizations. I then argue that, without any addition, this ontology provides us with physical necessities, and moreover with various grades of physical necessity, including the strongest grade, which I call absolute physical necessity. In addition there are consequences for our understanding of time. For this account, which I call the Mortmain Theory, provides a d…Read more

    Mereotopology without Mereology
    Journal of Philosophical Logic 39 (3): 229-254. 2010.
    Mereotopology is that branch of the theory of regions concerned with topological properties such as connectedness. It is usually developed by considering the parthood relation that characterizes the, perhaps non-classical, mereology of Space (or Spacetime, or a substance filling Space or Spacetime) and then considering an extra primitive relation. My preferred choice of mereotopological primitive is interior parthood . This choice will have the advantage that filters may be defined with respect …Read more

    In Defence of Anthropomorphic Theism
    European Journal for Philosophy of Religion 3 (1). 2011.
    I reply to seven objections to anthropomorphic theism: (1) That anthropomorphic theism is idolatrous. In reply I rely on the concept/conception distinction. (2) That faith requires certainty. In reply I argue that full belief may be based on probable inference. (3) That the truly infinite is incomprehensible. In reply I distinguish two senses of knowing what you mean. (4) "You Kant say that!" In reply I distinguish shallow from deep Kantianism. (5) "Shall Old Aquinas be forgot?" In reply I discu…Read more
