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.

This volume provides a vital student resource: a collection of the essential classic and contemporary readings in metaphysics.

This book presents and defends a large number of theses in ontology and meta-ontology. The meta-ontological theses are broadly Quinean: that existence or being is what is expressed by the existential quantifier of formal logic; that the variables the quantifiers bind are essentially third-person-singular pronouns; that the “ontological commitments” of a person or theory are best revealed when the sentences of the person or theory are translated into the quantifier-variable idiom. Much of the book is devoted to ontological, as opposed (...) to meta-ontological, questions: Are there things that do not exist—or even things that have no sort of being whatever? Are there universals—or, more generally, abstract objects? What sort of thing is a property (quality, attribute…)? What are the ontological commitments of modal discourse? Are there possible worlds? If there are, do some of them contain “non-actual” individuals? (The meta-ontology severely constrains the ontology. For example, a non-actual but possible individual is an individual thing that might exist but does not. Therefore, non-actual individuals do not exist. That is to say, there aren’t any.) The book closes with the presentation and defense of an ontology consistent with everything said in the earlier parts of the book. The central thesis of this ontology is that everything belongs to one of two ontological categories, substance and relation. Relations are universals, and propositions are special kinds of relation. Special consideration is given to the absence of sets from the ontology. (shrink)

An argument is presented for the truth of the conditional, ‘If New York is not in the United States, it's in California’. Several possible objections to this argument are then examined and evaluated. Further argument establishes that if the argument for the truth of ‘If New York is not in the United States, it's in California’ is sound, it follows that an indicative conditional is true if and only if it has either a false antecedent or a true consequent.

Peter van Inwagen, author of the classic book An Essay on Free Will, has established himself over the last forty years as a leading figure in the philosophical debate about the problem of free will. This volume presents eleven influential essays from throughout his career, as well as two new and previously unpublished essays, 'The Problem of Fr** W*ll' and 'Ability'. The essays include discussions of determinism, moral responsibility, 'Frankfurt counterexamples', the meaning of 'the ability to do otherwise', (...) and the very definition of free will, as well as critiques of writings on the topic by Daniel Dennett and David Lewis. An introduction by the author discusses the history of his thinking about free will. The volume will be a valuable resource for those looking to engage with van Inwagen's significant contributions to this perennially important topic. (shrink)

In this chapter, the problem of evil is understood in a narrow, intellectual sense: as the problem of how a theist can best reply to various arguments for the non-existence of God that are based on the fact that the world contains evil. Two such arguments are examined. One proceeds from a general fact about the world: that it contains a vast amount of truly horrendous evil. The other proceeds from a particular horrible event. It is argued that each of (...) these arguments is a “failure” in this sense: ideally rational agnostics, having reflected on the argument, could, without any offense against reason, remain agnostics.

Quine has called the question, ‘What is there?’ the “ontological question.” But if we call this question by that name, what name shall we use for the question, ‘What are we asking when we ask “What is there?”’? I shall call it ‘the meta-ontological question’. I shall call the attempt to answer the meta-ontological question ‘meta-ontology’ and any proposed answer to it ‘a meta-ontology’. In this essay, I shall briefly sketch a meta-ontology. The meta-ontology I shall present is broadly Quinean. (...) I am, in fact, willing to call it an exposition of Quine’s meta-ontology. (shrink)

Discusses the incompatibility of the concepts of free will and determinism and argues that moral responsibility needs the doctrine of free will.

This book gathers together thirteen of Peter van Inwagen's essays on metaphysics, several of which have acquired the status of modern classics in their field. They range widely across such topics as Quine's philosophy of quantification, the ontology of fiction, the part-whole relation, the theory of 'temporal parts', and human knowledge of modal truths. In addition, van Inwagen considers the question as to whether the psychological continuity theory of personal identity is compatible with materialism, and defends the (...) thesis that possible states of affairs are abstract objects, in opposition to David Lewis's 'extreme modal realism'. A specially-written introduction completes the collection, which will be an invaluable resource for anyone interested in metaphysics. (shrink)

The concept of the resurrection of the body (or of the dead) is most easily explained by laying out the ways in which it differs from the most important competing picture of the survival of death, the Platonic picture. It can be plausibly argued that the doctrine of the resurrection of the dead presupposes some form of dualism. The resurrection life, as the post‐resurrection stories of Jesus show, is a physical life, the life of an organism. A belief in a (...) general resurrection of the dead is one of many Judeo‐Christian elements that have been incorporated into Islam. Some who accept the doctrine of resurrection deny the existence of a separable, immaterial soul. Those human beings who refuse salvation will, after the general resurrection, be thrust into a condition that the New Testament describes by a mixture of three images: exclusion, pain, and refuse.

"This is an important book, and no one interested in issues which touch on the free will will want to ignore it."--Ethics. In this stimulating and thought-provoking book, the author defends the thesis that free will is incompatible with determinism. He disputes the view that determinism is necessary for moral responsbility. Finding no good reason for accepting determinism, but believing moral responsiblity to be indubitable, he concludes that determinism should be rejected.

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)

The topic of this book is material objects. Like most interesting concepts, the concept of a material object is one without precise boundaries.

Inwagen, Peter van_Dispensing with Ontological Levels.

Original: Peter van Inwagen, “C. S. Lewis’s Argument against Naturalism”, The Journal of Inklings Studies 1, no. 2 : 25–40. Translation with permission of the author. This paper is an evaluation of the argument of Chapter 3 of the second edition of C. S. Lewis’s Miracles. This argument is an attempt to demonstrate that naturalism implies that none of our beliefs is based on reasoning — a “cardinal difficulty for naturalism,” since a belief in naturalism that was not (...) based on reasoning would be irrational. The conclusion of the paper is Lewis’s argument fails to show that naturalism implies that none of our beliefs is based on reasoning. (shrink)

Philosophers of mind have not in general been very attentive to metaphysics. This book is a salutary exception to this general observation. A philosopher of mind—at least the body of her very influential work would be classified by most philosophers as belonging to the philosophy of mind—attempts to ground a theory of the relation between human persons and their bodies in an extended essay on the metaphysics of the natural world. Baker is a materialist : in her book, you and (...) I and everyone we know is a material thing. But then how are we material persons related to our bodies, which are also material things? Unlike many materialists, she rejects the following answer to this question: We are identical with our bodies. The bulk of this review is no more than a summary of her answer to the “person-body question.” My summary will use language very different from hers, since it will rely heavily on the language of parthood, and she is extremely hostile to any attempt to use the concept “part” in connection with her theory. Nevertheless, the use I make of this concept is innocuous, and my representation of her answer to the person-body question is accurate. (shrink)

The principle “Ought implies can” has important connections with the problem of free will. In this chapter, I lay out these connections and proceed to consider a recent exercise in “experimental philosophy” whose results some have regarded as constituting an important challenge to the principle. Although many, perhaps most, philosophers regard the principle as an analytic truth, a survey of non-philosophers conducted in 2016 has led its authors to conclude that non-philosophers do not accept the “Ought implies can” principle. The (...) main topics of this chapter are a critical evaluation of the authors’ interpretation of the results of their survey and an examination of the implications of those results for the question whether the principle is true.

God must create the best. But there is no best. Therefore, there is no God. Various philosophers—among them Stephen Grover and William Rowe—have endorsed more elaborate versions of this argument. Dean Zimmerman (in “Resisting Rowe’s No-Best-World Argument for Atheism”) has subjected their defenses of the argument to careful scrutiny—scrutiny that was in fact so careful that there remains very little to say about the argument. This essay contains my attempt to supply that very little.

If Pegasus existed, he would indeed be in space and time, but only because the word ‘Pegasus’ has spatio-temporal connotations, and not because ‘exists’ has spatio-temporal connotations. If spatio-temporal reference is lacking when we affirm the existence of the cube root of 27, that is simply because a cube root is not a spatio-temporal kind of thing.

In this paper I shall define a thesis I shall call ' determinism ', and argue that it is incompatible with the thesis that we are able to act otherwise than we do. Other theses, some of them very different from what I shall call ' determinism ', have at least an equal right to this name, and, therefore, I do not claim to show that every thesis that could be called ' determinism ' without historical impropriety is incompatible with (...) free will. I shall, however, assume without argument that what I call ' determinism ' is legitimately so called. In Part I, I shall explain what I mean by ' determinism '. In Part II, I shall make some remarks about 'can'. In Part III, I shall argue that free will and determinism are incompatible. In Part IV, I shall examine some possible objections to the argument of Part III. I shall not attempt to establish the truth or falsity of determinism, or the existence or nonexistence of free will.
