The title question is approached by distinguishing two senses of “God” and two senses of “cognitive” (or “cognitively meaningful”), producing four separate questions. Each is given an affirmative or negative answer, which is defended against possible objections. At the end, the debate between atheism and theological non-cognitivism is addressed, with the atheist side argued to have the preferable outlook.

This paper is a reply to Thomas Metcalf ’s “Entailment and ontological arguments: Reply to Maydole,” published in Philo 8, 2 (2005). Iargue that he fails to refute my Modal Perfection Argument for the existence of a Supreme Being, and that it remains arguably sound in the face of his alleged counterexamples and parody.

Bruce Russell has classified evidential arguments from evil into four types, one of which is the type-4 argument. Rather than begin with observations of evils that appear to be gratuitous, type-4 arguments simply begin with observations of evils. The next step, and the heart of a type-4 argument, is an abductive inference (inference to the best explanation) from those observations, to the conclusion that there is gratuitous evil. Reflection upon the consequential complexity of history, however, reveals that we have no objective grounds for making the key, abductive inference, thus, all type-4 arguments from evil fail.

In this essay I respond to comments on my work by Stephen T. Davis and Keith Parsons.

In this paper we respond to criticisms by Michael Bergmann and Michael Rea in their “In Defense of Sceptical Theism: A Reply to Almeida and Oppy,” Australasian Journal of Philosophy 83 (2005).

In his book Nonbelief & Evil, Theodore Drange argues that theists are likely to deploy the “unknown purpose defense” in the face of the existence of apparently gratuitous evils. That is, they will assert that God has morally sufficient reasons for permitting apparently gratuitous evil, but that humans do not know those reasons. Drange argues that by deploying the unknown purpose defense, and by challenging atheologians to prove that God does not have such unknown morally sufficient reasons, theists can achieve a stalemate with atheological challengers. I argue, however, that the epistemic burden of ascertaining whether God probably does or does not possess morally sufficient reasons for permitting evil falls asymmetrically on theists and atheists. Further, I argue that, given the failure of theodicies, the condition of nescience, the admission that we are in no position to assess whether God probably does or does not possess morally sufficient reasons for permitting ostensibly gratuitous evil, entails agnosticism about God’s existence. To escape agnosticism, theists will probably claim to have a warranted and properly basic belief in the existence and goodness of God. While I concede that theists may be doing their “epistemic best” in claiming such assurance, I argue that theists must concede that the existence of apparently gratuitous evil equally legitimizes nonbelief.

Robert Maydole has recently presented a sophisticated ontological argument that he calls the Modal Perfection Argument for the existence of a supreme being. While this ontological argument is probably better than most of its peers, it is nonetheless open to at least one decisive objection. The purpose of this brief comment is to develop that objection. I claim that this objection indicates an important further point about the concept of entailment and its role in ontological arguments at large, the recognition of which helps to refute other conceivable ontological arguments.

This paper is a reply to Graham Oppy’s “Maydole’s 2QS5 Argument,” published in Philo 7, 2 (2004). I argue that he fails to refute myModal Perfection Argument for the existence of a Supreme Being, and that it remains arguably sound in the face of his alleged counterexamples and parodies.

In this paper I argue that Robert Kane’s defense of event-causal libertarianism, as presented in Responsibility, Luck, and Chance: Reflections on Free Will and Indeterminism, fails because his event-causal reconstruction is incoherent. I focus on the notions of efforts and self-forming actions essential to his defense.

In a previous Philo article, it was shown how properties could be ontologically dispensed with via a representational analysis: to be an X is to comprehensively represent all the properties of an X. The current paper extends that representationalist (RT) theory by explaining representation itself in parallel epistemic rather than ontological terms. On this extended RT (ERT) theory, representations of X, as well as the real X, both may be identified as providing information about X, whether partial or comprehensive. But that information does not match ontological, property-based analyses of X, so it is epistemically fundamental—hence supporting a broadly conceptualist rather than nominalist metaphysics.

Suppose that a material object is gunky: all of its parts are located in space, and each of its parts has a proper part. Does it follow from this hypothesis that the space in which that object resides must itself be gunky? I argue that it does not. There is room for gunky objects in a space that decomposes without remainder into mereological simples.

When the atomic theory was revived in the seventeenth century, the atomists faced a problem concerning the status of the laws of nature. On the face of it, the postulation of absolutely hard, rigid, and impenetrable atoms seems to entail the existence of natural necessities and impossibilities: Atoms A and B cannot interpenetrate, so atom A must push atom B when they collide. The properties of compound bodies are to be explained in terms of their “textures” (i.e., the arrangements of their constituent atoms) on the famous lock-and-key model. Once again, it looks as if we have a domain of natural necessities depending on the textures of compound bodies. But the atomists seem to think of the laws of nature as radically contingent, not the sorts of things that could in principle be known a priori. This article seeks to address this tension between what the atomists seem committed to by their matter theory (real necessary connections in nature) and what they in fact say (that all the laws are contingent). In my Atomism (1995) I sought to resolve the tension by appealing to a sharp distinction between the atomists’ metaphysics and their epistemology. On this interpretation, they remain committed to natural necessity, but insist that we can never do Natural Philosophy in the “high priori” manner, by discovering real essences and their necessary connections. Our sciences of nature must remain empirical. Since publication of Atomism, however, this possible solution of the problem has come to seem more doubtful. Reflection on the work of my three “dissenting voices” (Margaret Osler, Peter Anstey and Rae Langton) has forced a radical rethink, focussing on the problematic relation between the intrinsic properties of the atoms and their (dynamic) powers. If there is no discoverable intelligible connection between what the atom is in itself (its intrinsic properties) and what it does (its powers), then my earlier solution will turn out to be untenable.

In this paper I present two new arguments against the possibility of an omniscient being. My new arguments invoke considerations of cardinality and resemble several arguments originally presented by Patrick Grim. Like Grim, I give reasons to believe that there must be more objects in the universe than there are beliefs. However, my arguments will rely on certain mereological claims, namely that Classical Extensional Mereology is necessarily true of the part-whole relation. My first argument is an instance of a problem first noted by Gideon Rosen and requires an additional assumption about the mereological structure of certain beliefs. That assumption is that an omniscient being’s beliefs are mereological simples. However, this assumption is dropped when I present my second argument. Thus, I hope to show that if Classical Extensional Mereology is true of the part-whole relation, there cannot be an omniscient being.

In my “Plantinga Untouched,” I argued that James Beilby’s recent objection to Plantinga’s EAAN was unsuccessful. Beilby has sincereplied that a naturalist can grant the Inscrutability Thesis and yet be alethically rational in hoping for a high P(R/N and future developments of E) and, therefore, needn’t accept the alethic defeater for R. I argue that this is impossible, since a naturalist cannot consistently grant that thesis and meet Beilby’s own criteria for alethic hope. Consequently, Plantinga is (still) right in maintaining that the naturalist who grants that P(R/N&E) is low or inscrutable has a defeater for R.

George Holmes Howison’s 1895 essay entitled “The Limits of Evolution,” argued that there are four things evolutionary theory does not explain. In examining whether 11 decades have made a difference in these four, I argue that the arrogance of scientists over the past century in refusing to distinguish between full explanations and explanatory hypotheses is in some ways responsible for the fundamentalist backlash against evolutionary science. A scientific community that is honest and forthcoming about its limitations is to be sought. The best response to Intelligent Design, Creation Science, and other current trends in pseudoscience is to be very clear about the limits of evolutionary theory and the scope of scientific explanation.

A mathematical model of the natural origin of our universe is presented. The model is based only on well-established physics. No claim is made that this model uniquely represents exactly how the universe came about. But the viability of a single model serves to refute any assertions that the universe cannot have come about by natural means.
