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

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 paper has two parts. In the first part, I concede an error in an argument I have given for the incompatibility of free will and determinism. I go on to show how to modify my argument so as to avoid this error, and conclude that the thesis that free will and determinism are compatible continues to be—to say the least—implausible. But if free will is incompatible with determinism, we are faced with a mystery, for free will undeniably exists, and (...) it also seems to be incompatible with indeterminism. In the second part of this paper, I will defend the conclusion that the concept of agent causation is of no use to the philosopher who wants to maintain that free will and indeterminism are compatible. I conclude that free will remains a mystery---that is, that free will undeniably exists and that there is a strong and unanswered prima facie case for its impossibility. (shrink)

Many important metaphysical arguments validly deduce an actuality from a possibility. For example: Because it is possible for me to exist in the absence of anything material, I am not my body. I argue that there is no reason to suppose that our capacity for modal judgment is equal to the task of determining whether the "possibility" premise of any of these arguments is true. I connect this thesis with Stephen Yablo's recent work on the epistemology of modal statements.

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)

In this essay I present what is, I contend, the free-will problem properly thought through, or at least presented in a form in which it is possible to think about it without being constantly led astray by bad terminology and confused ideas. Bad terminology and confused ideas are not uncommon in current discussions of the problem. The worst such pieces of terminology are "libertarian free will" and "compatibilist free will." The essay consists partly of a defense of the thesis that (...) the use of these phrases by writers on the problem of free will can only generate conceptual confusion and partly of a formulation of the problem that does not make use of them. I contend that this formulation is neutral with respect to the historically important positions on free will (e. g., compatibilism and incompatibilism). (shrink)

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)

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)

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

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)

The vast amount of suffering in the world is often held as a particularly powerful reason to deny that God exists. Now, one of the world's most distinguished philosophers of religion presents his own position on the problem of evil. Highly accessible and sensitively argued, Peter van Inwagen's book argues that such reasoning does not hold: his conclusion is not that God exists, but that suffering cannot be shown to prove that He does not.

Many philosophers think not. Many philosophers, in fact, seem to suppose that anyone who raises the question whether mereological sums can change their parts displays thereby a failure to grasp an essential feature of the concept “mereological sum.” It is hard to point to an indisputable example of this in print,[i] but it is a thesis I hear put forward very frequently in conversation (sometimes it is put forward in the form of an incredulous stare after I have said something (...) that implies that mereological sums can change their parts).

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)

_This is an account of his present thinking by an excellent philosopher who has been_ _among the two or three foremost defenders of the doctrine that determinism and_ _freedom are incompatible -- that logically we cannot have both. In his 1983 book,_ _An Essay on Free Will_ _, he laid out with unique clarity and force a fundamental_ _argument for this conclusion. What the argument comes to is that if determinism is_ _true, we are not free, since our actions are (...) effects of causal circumstances in the_ _remote past, and those circumstances are certainly not up to us. To that line of_ _thought, in the article below, by way of the supposition of a world of angels, he adds_ _something new. This is a fundamental difficulty with the freedom that we cannot_ _have if determinism is true. The difficulty, indeed a mystery, is one having to do with_ _the opposite of determinism -- indeterminism._. (shrink)
