Classical Christian orthodoxy insists that God is Triune: there is only one God, but there are three divine Persons — Father, Son, and Holy Spirit — who are somehow of one substance with one another. But what does this doctrine mean? How can we coherently believe that there is only one God if we also believe that there are three divine Persons? This problem, sometimes called the ‘threeness-oneness problem’ or the ‘logical problem of the Trinity’, is the focus of this interdisciplinary volume. It includes a selection of recent philosophical work on this topic, accompanied by a variety of essays by philosophers and theologians to further the discussion. The book is divided into four parts, the first three dealing in turn with the three most prominent models for understanding the relations between the Persons of the Trinity: Social Trinitarianism, Latin Trinitarianism, and Relative Trinitarianism. Each section includes essays by both proponents and critics of the relevant model. The volume concludes with a section containing essays by theologians reflecting on the current state of the debate.

In "Persons and Bodies," Lynne Baker defends what she calls the "Constitution View" of human persons, according to which (a) human persons are constituted by their bodies, and (b) constitution is an asymmetric, nontransitive relation that is somehow "intermediate between identity and separate existence". (Baker 2000: 29) Thesis (a), or something like it, is precisely what we would expect from someone who believes that persons and bodies both are material objects. But thesis (b) is distinctive. Materialists who treat constitution as identity arrive at the view that human persons are identical with their bodies, their brains, or some other material object in the vicinity of their heads. At the other extreme, materialists who treat constitution as nothing more than complete overlap without identity arrive at a simple coincidence theory of the relation between persons and bodies (or brains, or whatever). Baker's view is supposed to stake out a novel account of the nature of constitution.

An Introduction to the Philosophy of Religion provides a broad overview of the topics which are at the forefront of discussion in contemporary philosophy of religion. Prominent views and arguments from both historical and contemporary authors are discussed and analyzed. The book treats all of the central topics in the field, including the coherence of the divine attributes, theistic and atheistic arguments, faith and reason, religion and ethics, miracles, human freedom and divine providence, science and religion, and immortality. In addition it addresses topics of significant importance that similar books often ignore, including the argument for atheism from hiddenness, the coherence of the doctrines of the Trinity and the Incarnation, and the relationship between religion and politics. It will be a valuable accompaniment to undergraduate and introductory graduate-level courses.

The Christian doctrine of the Trinity poses a serious philosophical problem. On the one hand, it seems to imply that there is exactly one divine being; on the other hand, it seems to imply that there are three. There is another well-known philosophical problem that presents us with a similar sort of tension: the problem of material constitution. We argue in this paper that a relatively neglected solution to the problem of material constitution can be developed into a novel solution to the problem of the Trinity.

In debate about the nature of persistence over time, the view that material objects endure has played the role of "champion" and the view that they perdure has played the role of the "challenger." It has fallen to the perdurantists rather than the endurantists to motivate their view, to provide reasons for accepting it that override whatever initial presumption there is against it. Perdurantists have sought to discharge their burden in several ways. For example, perdurantism has been recommend on the grounds that: (i) it solves several of the puzzles that raise the problem of material constitution; (ii) it is (at least) suggested by the special theory of relativity (hereafter "SR"); (iii) it is the only view that makes sense out of the possibility of intrinsic change; (iv) it is the only view consistent with the doctrine of Humean supervenience; and (v) it makes better sense than its competitor out of the possibility of fission. There are primary and most powerful claims that have been made on behalf of perdurantism. They are individually persuasive and together they constitute a formidable assault upon the hegemony of endurantism. Endurantists of course, have not been without reply. However, since endurantists typically respond to these claims one at a time and in different ways, it is easy to get the impression that perdurantism offers a single, neat solution to a host of problems whereas endurantism requires a patchwork of different strategies. But this impression is an illusion. In Rea 1995, I argued that though perdurantism does solve some of the puzzles that raise the problem of material constitution, it does not solve the problem of material constitution itself. Thus, the problem of material constitution really has no bearing on the debate between endurantists and perdurantists. In his paper, I will show that the same is true with respect to SR, the problem of intrinsic change, the doctrine of Humean supervenience, and the possibility of fission. In short, I will argue that none of (ii-v) is true and that therefore the doctrine of temporal parts stands unmotivated.

The paper will have three sections. In section one I briefly present and respond to Byrne’s argument against theological realism. In section two, I present van Fraassen’s argument against analytic metaphysics and I show how, if sound, it constitutes a reason to reject both metaphysical and theological realism. In section three, I show how van Fraassen can be answered. Obviously what I am doing here falls far short of a full-blown defense of realism in either metaphysics or theology. But the objections raised by van Fraassen and Byrne are tokens of a type of objection that I think is rather widely endorsed among those who are suspicious of these two brands of realism. Thus, responding to those objections constitutes an important first step in the direction of a defense.

The chapter has four parts. In the first, I argue that we can be justified in believing that there are mind-independent material objects only if we can be justified in believing that modal properties are exemplified in at least some of the regions of space-time that we take to be occupied by material objects. In the second, I argue that we can be justified in believing that modal properties are exemplified in a region only if we can be justified in classificatory judgments--judgments like 'this region contains an F', where 'F' is a name for a natural kind and furthermore constitutes a metaphysically better answer to the question, "What kind of object is in that region?" than any name for any other kind. In the third part, I dismiss as failures three views about how naturalists might be able to be justified in classificatory judgments. I consider a fourth which presupposes that, if there are material objects, then we are justified in believing that science reveals some of them to have proper functions; and I note that if this fourth proposal fails, there is good reason to think that any other proposal will as well. In the final section I argue that this fourth proposal does indeed fail by showing that there are material objects, science does not reveal any of them to have proper functions. If I am right, and if (as seems plausible) we are justified in believing that there exist mind-independent material objects (e.g. people), then we ought to reject naturalism.

Drawing in part on recent work by Eleonore Stump and Sarah Coakley, I shall argue that even if NO HUMAN GOOD is true, divine hiddenness does not cast doubt on DIVINE CONCERN. My argument will turn on three central claims: (a) that ABSENCE OF RELIGIOUS EXPERIENCE and INCONCLUSIVE EVIDENCE are better thought of as constituting divine silence rather than divine hiddenness, (b) that even if NO HUMAN GOOD is true, divine silence is compatible with DIVINE CONCERN so long as God has provided a way for rational creatures to find him and to experience his presence despite the silence, and (c) that there is some reason to think that Biblical narratives and liturgical acts are vehicles by which we might find and experience the presence of God. Each of these claims will be defended, in turn, in the three sections that follow.

Philosophical theology is aimed primarily at theoretical understanding of the nature and attributes of God and of God's relationship to the world and its inhabitants. During the twentieth century, much of the philosophical community had grave doubts about our ability to attain any such understanding. In recent years the analytic tradition in particular has moved beyond the biases that placed obstacles in the way of the pursuing questions located on the interface of philosophy and religion. The result has been a rebirth of serious, widely-discussed work in philosophical theology. The Oxford Handbook of Philosophical Theology attempts both to familiarize readers with the directions in which this scholarship has gone and to pursue the discussion into hitherto under-examined areas. Written by some of the leading scholars in the field, the essays in the Handbook are grouped in five sections. In the first, articles focus on the authority of scripture and tradition, on the nature and mechanisms of divine revelation, on the relation between religion and science, and on theology and mystery. The next section focuses on philosophical problems connected with the central divine attributes: aseity, omnipotence, omniscience, and the like. In Section Three, essays explore theories of divine action and divine providence, questions about petitionary prayer, problems about divine authority and God's relationship to morality and moral standards, and various formulations of and responses to the problem of evil. The fourth section examines philosophical problems that arise in connection with such central Christian doctrines as the trinity, the incarnation, the atonement, original sin, resurrection, and the Eucharist. Finally, Section Five introduces readers to work that is being done in Jewish, Islamic, and Chinese philosophical theology.
