In response to arguments against the existence of God, and in response to perceived conflicts between divine attributes, theists often face pressure to give up some pretheoretically attractive thesis about the divine attributes. One wonders: when does this unacceptably water down our concept of God, and when is it, as van Inwagen says, ‘permissible tinkering’ with the concept of God? A natural and widely deployed answer is that it is permissible tinkering iff it is does not violate the claim that (...) God is the greatest possible being. Call this the ’perfect being defense.’ In this paper I lay out some influential uses of the perfect being defense, and then argue that this strategy for defending theism fails. (shrink)

William L. Rowe’s argument against divine freedom has drawn considerable attention from theist philosophers. One reply to Rowe’s argument that has emerged in the recent literature appeals to modified accounts of libertarian freedom which have the result that God may be free even if he necessarily actualizes the best possible world. Though in many ways attractive, this approach appears to lead to the damning consequence of modal collapse i.e., that the actual world is the only possible world. But appearances can (...) be deceiving, and in this paper I argue that the threat of modal collapse dissolves when we consider Alvin Plantinga’s critique of the purportedly Leibnizian notion that God can actualize any possible world, and incorporate the implications of this critique into the divine freedom debate. Developing a suggestion by Edward R. Wierenga, I argue first that the modal collapse objection fails within a Molinist context, and then I extend the discussion beyond that context to show that the objection also fails on the assumption that Molinism is false.

The modal argument against materialism, in its most standard form, relies on a compatibility thesis to the effect that the physical truths are compatible with the absence of consciousness. I propose an alternative modal argument that relies on an incompatibility thesis: The existence of consciousness is incompatible with the proposition that the physical truths provide a complete description of reality. I show that everyone who accepts the premises of the standard modal argument must accept the premises of the revised modal (...) argument, but not vice versa. (shrink)

One can readily conceive of worlds of horrendous, gratuitous suffering. Moreover, such worlds seem possible. For classical theists, however, God, amongst other things, is perfectly good. So, the question arises: for classical theists are such evil worlds possible? Many classical theists have said no. This is the modal problem of evil. Herein, I discuss a related problem: the problem of evil worlds for Lewisian theism. Lewisian theism is the conjunction of Lewis’s modal realism and classical theism, and a leading Lewisian (...) theist, Almeida, thinks that Lewisian theists should admit the existence of on-balance evil worlds. I do not. Herein, I present a dilemma for Almeida: either give up God’s sovereignty and the reductionist account of modality or make God blameworthy for evil. (shrink)

By defining God as a maximally great being Plantinga is able to devise an ontological argument which validly infers from the possibility of there being a God that there necessarily is a God. In this article I shall argue that Plantinga’s argument is not only question-begging, as several critics have complained, but circular in the strongest sense of the term. Based on reflections on the relation between the notions of coherence and possibility, I shall defend two arguments, previously proposed by (...) Tooley and Guleserian, against the existence of a maximally great being. The article concludes with some critical remarks on Plantinga’s rationale for conceiving God as such a being. (shrink)

This paper examines "moderate modal skepticism", a form of skepticism about metaphysical modality defended by Peter van Inwagen in order to blunt the force of certain modal arguments in the philosophy of religion. Van Inwagen’s argument for moderate modal skepticism assumes Yablo's (1993) influential world-based epistemology of possibility. We raise two problems for this epistemology of possibility, which undermine van Inwagen's argument. We then consider how one might motivate moderate modal skepticism by relying on a different epistemology of possibility, which (...) does not face these problems: Williamson’s (2007: ch. 5) counterfactual-based epistemology. Two ways of motivating moderate modal skepticism within that framework are found unpromising. Nevertheless, we also find a way of vindicating an epistemological thesis that, while weaker than moderate modal skepticism, is strong enough to support the methodological moral van Inwagen wishes to draw.

Michael Almeida once told me that he thought we were just a couple of hours of conversation away from reaching deep agreement about some important topics in the philosophy of religion pertaining to God, multiverses, and modality. This paper represents my attempt to move this conversation forward and to seek this common ground. Specifically, I respond to Almeida’s paper entitled “The Multiverse and Divine Creation”. In the first four sections, I record my disagreement with him concerning some smaller matters. In (...) Section 5, I try to persuade him that what he considers a ‘bug’ in the theistic multiverse is actually a feature—and a desirable one at that. In Section 6, I close by identifying some points at which our views seem to converge. (shrink)
