It is widely agreed among broadly Anselmian theists that God is in some sense the 'delimiter of possibilities.' In other words, the scope of possibility is explained by the manner in which the universe emanates from God. However, existing accounts of God's role here—in terms of freedom, choice, or power—face serious difficulties. The present paper provides a new account of God's role as the delimiter of possibilities in terms of the different manner in which the non-actuality of non-actual states of (...) affairs is explained. Intuitively and metaphorically, we can think of the menu of states of affairs being 'whittled down' in successive stages of a process of divine decision-making, with the different species of impossibility corresponding to when and how the states of affairs are ruled out. I argue that this approach provides genuine contingency while also preserving the Principle of Sufficient Reason. (shrink)

As it is presently employed, grounding permits grounding many things from one ground. In this paper, I show why this is a mistake by pushing for a uniqueness principle on grounding. After arguing in favor of this principle, I say something about it and kinds of grounding, discuss a similar principle, and consider its import on a formal feature of grounding, ontology, and ontological simplicity.

This volume announces a new era in the philosophy of God. Many of its contributions work to create stronger links between the philosophy of God, on the one hand, and mathematics or metamathematics, on the other hand. It is about not only the possibilities of applying mathematics or metamathematics to questions about God, but also the reverse question: Does the philosophy of God have anything to offer mathematics or metamathematics? The remaining contributions tackle stereotypes in the philosophy of religion. The (...) volume includes 35 contributions. It is divided into nine parts: 1. Who Created the Concept of God; 2. Omniscience, Omnipotence, Timelessness and Spacelessness of God; 3. God and Perfect Goodness, Perfect Beauty, Perfect Freedom; 4. God, Fundamentality and Creation of All Else; 5. Simplicity and Ineffability of God; 6. God, Necessity and Abstract Objects; 7. God, Infinity, and Pascal's Wager; 8. God and (Meta-)Mathematics; and 9. God and Mind. (shrink)

Leibniz is often cited as an authority when it comes to the formulation and answer strategy of the question “Why is there something rather than nothing?” Yet much current research assumes that Leibniz advocates an unambiguous question and strategy for the answer. In this respect, one repeatedly finds the argument in the literature that alternative explanatory approaches to this question violate Leibniz’s intention, since he derives the question from the principle of sufficient reason and also demands a causal explanation to (...) the question. In particular, the new research on non-causal explanatory strategies to the Leibniz question seems to concern this counter-argument. In this paper, however, I will argue that while Leibniz raises the question by means of the principle of sufficient reason, he even favours a non-causal explanatory strategy to the question. Thus, a more accurate Leibniz interpretation seems not only to legitimise but also to support non-causal explanations to the Leibniz question. (shrink)

This chapter aims to explore the intersection of Christian theism, a neo-Aristotelian gloss on metaphysical grounding, and creaturely participation in God. In section one, I aim to de- velop several core tenets at the heart of a theistic participatory ontology as it is found in the Christian tradition, what I call minimal participatory ontology. In section two, I examine the contemporary notion of metaphysical grounding, namely the formal and structure features of the grounding relation, and offer a grounding-theoretic framework for (...) understanding a mini- mal participatory ontology. Finally, in section three, I put forward a neo-Aristotelian account of metaphysical grounding in particular, one that is uniquely suited to capture the central tenets of minimal participatory ontology.

It is sometimes supposed that, in principle, we cannot offer an explanation for why there is something rather than nothing. I argue that this supposition is a mistake, and stems from a needlessly myopic conception of the form explanations can legitimately take. After making this more general point, I proceed to offer a speculative suggestion regarding one sort of explanation which can in principle serve as an answer to the question “why is there something rather than nothing?” The suggestion is (...) that there may be something rather than nothing in virtue of the truth of certain sorts of subjunctive conditionals.

In this paper I argue for the incompatibility of three claims, each of them quite attractive to a theist. First, the doctrine of deep dependence: the universe depends for its existence, in a non-causal way, on God. Second, the doctrine of true transcendence: the universe is wholly distinct from God; God is separate and apart from the universe in respect of mereology, modes, and mentality. Third, the doctrine of robust creaturely freedom: some creature performs some act such that he could (...) have done other than he in fact did. After laying out the claims, I show that their conjunction has its adherents—most clearly, the medieval Jewish philosopher, Maimonides. I then argue in detail that the claims are in fact incompatible. I conclude with a discussion of which of the claims is best jettisoned, drawing in part on the work of the Absolute Idealist, Mary Calkins. (shrink)

This paper presents a new cosmological argument based on considerations about grounding. I argue that, by assuming three plausible principles about grounding, we can construct a cosmological argument for the existence of a unique ungrounded being that ultimately grounds everything else. At the end of the paper I consider two possible objections, and offer my replies to them.

I use Plotinus to present absolute divine simplicity as the consequence of principles about metaphysical and explanatory priority to which most theists are already committed. I employ Phil Corkum’s account of ontological independence as independent status to present a new interpretation of Plotinus on the dependence of everything on the One. On this reading, if something else (whether an internal part or something external) makes you what you are, then you are ontologically dependent on it. I show that this account (...) supports Plotinus’s claim that any entity with parts cannot be fully independent. In particular, I lay out Plotinus’s case for thinking that even a divine self-understanding intellect cannot be fully independent. I then argue that a weaker version of simplicity is not enough for the theist since priority monism meets the conditions of a moderate version of ontological independence just as well as a transcendent but complex ultimate being.

General discussion of grounding, including its formal features, relations to other notions, and applications. (Originally published 2014; revised 2021).

According to classical theism, the universe depends on God in a way that goes beyond mere (efficient) causation. I have previously argued that this ‘deep dependence’ of the universe on God is best understood as a type of grounding. In a recent paper in this journal, Aaron Segal argues that this doctrine of deep dependence causes problems for creaturely free will: if our choices are grounded in facts about God, and we have no control over these facts, then we do (...) not control our choices and are therefore not free. This amounts to a grounding analogue of the Consequence Argument for the incompatibility of free will and determinism. If successful, it would have application beyond classical theism: similar concerns would apply to any view that takes our choices to be grounded in a deeper reality which is beyond our control. However, I show that the argument is not successful. Segal’s Grounding Consequence Argument is so closely analogous to the Causal Consequence Argument that any response to the one provides a response to the other. As a result, if you don’t think that prior causes (whether deterministic or indeterministic) undermine free will, you shouldn’t think that prior grounds undermine free will. (shrink)

Divine Foundationalism is the thesis that God is the source of all things (apart from God hirself). I clarify and defend the thesis, before I consider the main arguments for and against it.

This paper will examine a novel argument in favour of entity grounding over fact-only grounding. The idea of this argument, roughly speaking, is that the proponents of fact-only grounding cannot provide a unified account of grounds of identity, whereas the proponents of entity grounding can. In this paper, I will give a response to this argument. Specifically, I will argue that the problem which this argument raises to the proponents of fact-only grounding is also a problem with which the proponents (...) of entity grounding are faced. Therefore, this argument fails to show that entity grounding is superior to fact-only grounding. Moreover, I will suggest that the failure of this argument points to a general lesson about the issue of grounds of identity facts. (shrink)

Can I be free to perform an action if God has decided to ensure that I do not choose that action? I show that Molinists and simple foreknowledge theorists are committed to answering in the affirmative. This is problematic for their status as theological incompatibilists. I suggest that strategies for preserving their theological incompatibilism in light of this result should be based on sourcehood. However, the path is not easy here either, since Leibniz has shown how theological determinists can offer (...) an extremely robust form of sourcehood. Proponents of these views must identify a valuable form of sourcehood their theories allow that Leibniz’s theory doesn’t. (shrink)

This paper provides a new defence against the logical problem of evil, based on the naturalistic functional/teleological theory of mind (NFT). I argue that if the NFT is self-consistent then it is consistent with theism. Further, the NFT entails that it is not possible for created minds to exist in the absence of evil. It follows that if the NFT is self-consistent then the existence of God is consistent with the existence of evil.

Daniel C. Dennett has long maintained that the Consequence Argument for incompatibilism is confused. In a joint work with Christopher Taylor, he claims to have shown that the argument is based on a failure to understand Logic 101. Given a fairly plausible account of having the power to cause something, they claim that the argument relies on an invalid inference rule. In this paper, I show that Dennett and Taylor’s refutation does not work against a better, more standard version of (...) the Consequence Argument. Therefore, Dennett and Taylor’s alleged refutation fails. (shrink)
