As I will use the term, an object is a mereological sum of some things just in case those things compose it simply in virtue of existing. In the first half of this paper, I argue that there are no sums. The key premise for this conclusion relies on a constraint on what, in certain cases, it takes for something to ground, or metaphysically explain, something else. In the second half, I argue that in light of my argument against sums, (...) Universalism, which is perhaps the most widely accepted answer to the Special Composition Question, is false. (shrink)

Surprisingly few articles have focused on Aquinas’s particular conception of necessary beings in the Third Way, and many scholars have espoused inaccurate or incomplete views of that conception. My aim in this paper is both to offer a corrective to some of those views and, more importantly, to provide compelling answers to the following two questions about the necessary beings of the Third Way. First, how exactly does Aquinas conceive of these necessary beings? Second, what does Aquinas seek to accomplish (...) in the third stage of the Third Way? In answering these questions, I challenge prominent contemporary understandings of the necessary beings of the Third Way. (shrink)

Several theistic arguments are formulated as arguments for the best explanation. This article discusses how one can determine that some phenomenon actually needs an explanation. One way to demonstrate that an explanation is needed is by providing one. The proposed explanation ought to either make the occurrence of the phenomenon in question more probable than it occurring by chance, or it has to sufficiently increase our understanding of the phenomenon. A second way to demonstrate that an explanation is needed is (...) to show that the phenomenon in question both violates our expectations and is particularly noticeable. (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)

Divine necessity is the thesis that God must exist. In this paper, I give a brief survey of what the thesis is more exactly, the main arguments for it, and the main arguments against it.

The doctrine of divine simplicity has recently been ably defended, but very little work has been done considering reasons to believe God is simple. This paper begins to address this lack. I consider whether divine aseity or the related notion of divine sovereignty provide us with good reason to affirm divine simplicity. Divine complexity has sometimes been thought to imply that God would possess an efficient cause; or, alternatively, that God would be grounded by God’s constituents. I argue that divine (...) complexity implies neither of these, and so that a complex God could also exist a se. Similarly, a complex God might be thought less sovereign than a simple God, due to lacking control over the divine constituents. I argue in reply that a complex God either has just as much control as a simple God, or that a complex God’s relative lack of control should cause no theological problems. The upshot is that neither the doctrines of divine aseity or of divine sovereignty give theists good reason to endorse divine simplicity. (shrink)

Discussions on hypothetical gods virtually always focus on the latter’s existence or nonexistence. However, this is only the secondary question. Heroical apatheism distinguishes these questions from the primary question, which pertains to the importance of these gods. It is a deeply ingrained assumption that if the gods have created the universe and humankind, then this implicitly entails the obligations that these gods must be worshipped and obeyed. These relations between existence and acts and worship and obedience to the gods are (...) so commonplace that virtually no one questions their existence. The rights of these gods are simply assumed at face value. However, the issues pertaining to these necessary relations are not trivial in any respect. This paper highlights these relations by first formulating two cosmological models for the initial condition of the universe and, thereafter, applying these in the analyses of the claims regarding these relations. By doing so, it shows that the justifications for the aforementioned obligations always result in a Münchhausen bootstrapping circularity or are ad hoc. Any necessary relations between existence and worship and between acts of creation and obedience cannot be demonstrated. Furthermore, these assumptions are based on the frequently overlooked reasoning that arguing for or against the obligations to the gods implicitly assumes that these gods have a right to such obligations to begin with. However, all that can be shown is the power to enforce obedience. Thus, heroical apatheism is founded on neither doubt nor disobedience because disobedience implies that an authority exists and an authority’s right presupposes that there is such a right. However, there is no such right, and we do not equate might with right. (shrink)
