The relationship of part to whole is one of the most fundamental there is; this is the first and only full-length study of this concept. This book shows that mereology, the formal theory of part and whole, is essential to ontology. Peter Simons surveys and criticizes previous theories, especially the standard extensional view, and proposes a more adequate account which encompasses both temporal and modal considerations in detail. 'Parts could easily be the standard book on mereology for the next twenty (...) or thirty years.' Timothy Williamson, Grazer Philosophische Studien. (shrink)

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. (shrink)

Many materialist ontologies characterize the existence of everyday, middle-sized objects as reducible to collections or mereological sums of smaller, more fundamental particle constituents. Baker would have it otherwise and has set out a defence of her Constitution View of ontology that takes everyday objects to be irreducibly real and of a vast array of kinds.Motivating an interest in the metaphysics of everyday objects is not obviously straightforward when contemporary metaphysics is filled with attempts to answer seemingly more challenging questions about (...) the existence of disputed classes of objects, such as abstracta, or very specific, unusual phenomena such as holes, rather than the mundane case of these middle-sized concreta. Yet this is Baker's point: that many kinds of ordinary objects have been overlooked by philosophers to the point where we lack an adequate account of their significance in our practices and attitudes. Moreover, in a climate of metaphysics often governed by those of a strong eliminitivist inclination with a preference for Quinean desert landscapes, the advocating of an almost indulgent ontological pluralism is enough to make this book worth reading.Those familiar with Baker's work will not be surprised that this approach to ontology is grounded from her perspective of ‘Practical Realism’. This view – partly a legacy of Aristotle, partly of G. E. …. (shrink)

In this important study D. M. Armstrong offers a comprehensive system of analytical metaphysics that synthesises but also develops his thinking over the last twenty years. Armstrong's analysis, which acknowledges the 'logical atomism' of Russell and Wittgenstein, makes facts the fundamental constituents of the world, examining properties, relations, numbers, classes, possibility and necessity, dispositions, causes and laws. All these, it is argued, find their place and can be understood inside a scheme of states of affairs. This is a comprehensive and (...) rigorously this-worldly account of the most general features of reality, argued from a distinctive philosophical perspective, and it will appeal to a wide readership in analytical philosophy.

According to Peter van Inwagen, visible inanimate objects do not, strictly speaking, exist. In defending this controversial thesis, he offers fresh insights on such topics as personal identity, commonsense belief, existence over time, the phenomenon of vagueness, and the relation between metaphysics and ordinary language.

Lynne Rudder Baker and many others think that paradigmatic instances of one object constituting another—a piece of marble constituting a statue, or an aggregate of particles constituting a living body—involve two distinct objects in the same place at the same time. Some who say this believe in the doctrine of temporal parts; but others, like Baker, reject this doctrine. Such philosophers, whom one might call “coincidentalists”, cannot say that these objects manage to share space in virtue of sharing a temporal (...) part confined to just that place and time. But what can or should coincidentalists say about the nature of constitution? Many have analyzed the relation as one of sharing, “at some level”, all and only the same parts. Most have agreed that such massive part-sharing is at least a central component of and necessary condition for constitution. The heart of Baker’s Persons and Bodies, and its most significant contribution to the development of coincidentalism, is a theory of constitution that makes no appeal to mereology. The leading idea in Baker’s account is, instead, a modal one: objects belonging to constituted kinds are the necessary result of putting objects belonging to appropriate constituting kinds in the right circumstances, circumstances which the constituting objects need not have been in. So putting a piece of man-shaped marble in the right circumstances necessarily results in the existence of a second object, a statue, constituted by the marble; but the piece of marble need not have fallen into these circumstances or any others in which it would constitute a statue.

This paper develops an interpretation of the doctrine of the Trinity, drawn from Augustine and the Athanasian Creed. Such a doctrine includes divinity claims (the persons are divine), diversity claims (the persons are distinct), and a uniqueness claim (there is only one God). I propose and defend an interpretation of these theses according to which they are neither logically incompatible nor do they do entail that there are three (or four) gods.

One often hears a complaint about “bare particulars”. This complaint has bugged me for years. I know it bugs others too, but no one seems to have vented in print, so that is what I propose to do. (I hope also to say a few constructive things along the way.) The complaint is aimed at the substratum theory, which says that particulars are, in a certain sense, separate from their universals. If universals and particulars are separate, connected to each other (...) only by a relation of instantiation, then, it is said, the nature of these particulars becomes mysterious. In themselves, they do not have any properties at all. They are nothing but a pincushion into which universals may be poked. They are Locke’s “I know not what” (1689, II, xxiii, §2); they are Plato’s receptacles (Timaeus 48c–53c); they are “bare particulars”.1 Against substratum theory there is the bundle theory, according to which particulars are just bundles of universals. The substratum and bundle theories agree on much. They agree that both universals and particulars exist. And they agree that a particular in some sense has universals. (I use phrases like ‘particular P has universal U ’ and ‘particular P ’s universals’ neutrally as between the substratum and bundle theories.) But the bundle theory says that a particular is exhaustively composed of (i.e., is a mereological fusion of) its universals. The substratum theory, on the other hand, denies this. Take a particular, and mereologically subtract away its universals. Is anything left? According to the bundle theory, no. But according to the substratum theory, something is indeed left. Call this remaining something a thin particular. The thin particular does not contain the universals as parts; it instantiates them. (shrink)

This book, one of the first full-length studies of the modalities to emerge from the debate to which Saul Kripke, David Lewis, Ruth Marcus, and others are contributing, is an exploration and defense of the notion of modality de re, the idea that objects have both essential and accidental properties. Plantinga develops his argument by means of the notion of possible worlds and ranges over such key problems as the nature of essence, transworld identity, negative existential propositions, and the existence (...) of unactual objects in other possible worlds. He also applies his logical theories to the elucidation of two problems in the philosophy of religion: the problem of evil and the ontological argument. (shrink)

Sets of contingent objects, perhaps, are as contingent as their members; but properties, propositions, numbers and states of affairs, it seems, are objects whose non-existence is quite impossible. If so, however, how are they related to God? Suppose God has a nature: a property he has essentially that includes each property essential to him. Does God have a nature? And if he does, is there a conflict between God's sovereignty and his having a nature? How is God related to such (...) abstract objects as properties and propositions? These are the questions I want to explore. - Introduction. (shrink)

This paper is a reflection on two ontological analogies that have played a role in discussion about the Trinity---the Modalist and Social analogies. I argue that the Modal analogy commits one to a view of the divine persons that comports poorly with Scripture. I then consider two arguments to the effect that the doctrine of the Trinity commits one to tritheism. I argue that the Social analogy contains better resources for handling these arguments than the more traditional position, which involves (...) denying that the divine persons are substances.

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.

The problem of the nature of being was central to ancient and medieval philosophy, and continues to be relevant today. In this collection of thirteen recent essays, Peter van Inwagen applies the techniques of analytical philosophy to a wide variety of problems in ontology and meta-ontology. Topics discussed include the nature of being, the meaning of the existential quantifier, ontological commitment, recent attacks on metaphysics and ontology, the concept of ontological structure, fictional entities, mereological sums, and the ontology of mental (...) states. Van Inwagen adopts a generally 'Quinean' position in meta-ontology, yet reaches ontological conclusions very different from Quine's. The volume includes two previously unpublished essays, one of which is an introductory essay where van Inwagen explains his conception of the relation between the language of 'the ordinary business of life' and that of 'the ontology room'. The volume will be an important collection for students and scholars of metaphysics. (shrink)

Many contemporary philosophers are interested in the scotistic notion of haecceity or `thisness' because it is relevant to important problems concerning identity and individuation, reference, modality, and propositional attitudes. Haecceity is the only book-length work devoted to this topic. The author develops a novel defense of Platonism, arguing, first, that abstracta - nonqualitative haecceities - are needed to explain concreta's being diverse at a time; and second, that unexemplified haecceities are then required to accommodate the full range of cases in (...) which there are possible worlds containing individuals not present in the actual world. In the cognitive area, an original epistemic argument is presented which implies that certain haecceities can be grasped by a person: his own, those of certain of his mental states, and those of various abstracta, but not those of external things. It is argued that in consequence there is a clear sense in which one is directly acquainted with the former entities, but not with external things. (shrink)

Philosophy, science, and common sense all refer to propositions--things we believe and say, and things which are true or false. But there is no consensus on what sorts of things these entities are. Jeffrey C. King, Scott Soames, and Jeff Speaks argue that commitment to propositions is indispensable, and each defend their own views on the debate.
