The question raised by this volume is “How successful is naturalism?” The question presupposes that we already know what naturalism is and what counts as success. But, as anyone familiar with the literature on naturalism knows, both suppositions are suspect. To answer the question, then, we must first say what we mean in this context by both ‘naturalism’ and ‘success’. I’ll start with ‘success’. I will then argue that, by the standard of measurement that I shall identify here, naturalism is an utter failure.

In World Without Design: The Ontological Consequences of Naturalism, I argued that there is an important sense in which naturalism’s current status as methodological orthodoxy is without rational foundation, and I argued that naturalists must give up two views that many of them are inclined to hold dear—realism about material objects and materialism. In a review recently published in Faith and Philosophy, Dale Jacquette alleges that my arguments in World Without Design are directed mainly against strawmen and that I have neglected to discuss at least one formulation of naturalism that straightforwardly addresses my main objections. In this reply, I show that these and other objections raised by Jacquette are unsound and, in fact, rest on egregious misrepresentations of the book.

In this paper I provide a metaphysical account of the incarnation that starts from substantive assumptions about the nature of natures and about the metaphysics of the Trinity and develops in light of these a story about the relations among the elements involved in the incarnation. Central to the view I will describe are two features of Aristotle's metaphysics, though I do not claim that my own development of these ideas is anything of which Aristotle himself would have approved: (i) a hylomorphic understanding of material objects; (ii) a doctrine of numerical sameness without identity; and (iii) the view that the nature of a thing can appropriately be identified with its form. These ideas, along with other important aspects of the metaphysical framework with which I shall be working, are laid out in the first five sections below, followed in the sixth section by a brief sketch of the account of the Trinity that Jeff Brower and I have presented in detail elsewhere. In the final section, I present my account of the incarnation.

In this paper, I present an Aristotelian solution to the problem of material constitution. The problem of material constitution arises whenever it appears that an object a and an object b share all of the same parts and yet are essentially related to their parts in different ways. (A familiar example: A lump of bronze constitutes a statue of Athena. The lump and the statue share all of the same parts, but it appears that the lump can, whereas the statue cannot, survive radical rearrangements of those parts.) I argue that if we are prepared to follow Aristotle in making a distinction between numerical sameness and identity, we can solve the problem of material constitution without recourse to co-location or contingent identity and without repudiating any of the familiar objects of common sense (such as lumps and statues) or denying that these objects have the essential properties we ordinarily think that they have.

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.
