The paper has two parts: First, I describe a relatively popular thesis in the philosophy of propositional attitudes, worthy of the name ‘taking tense seriously’; and I distinguish it from a family of views in the metaphysics of time, namely, the A-theories (or what are sometimes called ‘tensed theories of time’). Once the distinction is in focus, a skeptical worry arises. Some A-theorists maintain that the difference between past, present, and future, is to be drawn in terms of what exists: (...) growing-block theorists eschew ontological commitment to future entities; presentists, to future and past entities. Others think of themselves as A-theorists but exclude no past or future things from their ontology. The metaphysical skeptic suspects that their attempt to articulate an ‘eternalist’ version of the A-theory collapses into merely ‘taking tense seriously’– a thesis that does not imply the A-theory. The second half of the paper is the search for a stable eternalist A-theory. It includes discussion of temporary intrinsics, temporal parts, and truth. (shrink)

Let us say that an extended object is “composed wholly of simples” just in case it is an aggregate of absolutely unextended parts spread throughout an extended region—that is, just in case there is a set S such that: every member is a point-sized part of the object, and for every x, x is part of the object if and only if it has a part in common with some member of S. Could a truly extended substance be composed entirely (...) of unextended parts? Reflection upon the fact that it must be at least possible for extended objects to touch one another suggests that the answer to this question is: No. (shrink)

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

The Oxford Handbook of Metaphysics offers the most authoritative and compelling guide to this diverse and fertile field of philosophy. Twenty-four of the world's most distinguished specialists provide brand-new essays about 'what there is': what kinds of things there are, and what relations hold among entities falling under various categories. They give the latest word on such topics as identity, modality, time, causation, persons and minds, freedom, and vagueness. The Handbook's unrivaled breadth and depth make it the definitive reference work (...) for students and academics across the philosophical spectrum. (shrink)

The ‘friends of temporal parts’ and their opponents disagree about how things persist through time. The former, who hold what is sometimes called a ‘4D’ theory of persistence, typically claim that all objects that last for any period of time are spread out through time in the same way that spatially extended objects are spread out through space — a different part for each region that the object fills. David Lewis calls this manner of persisting ‘perdurance’. The opposing, ‘3D’ theory (...) has it that at least some objects do not persist in this manner; they ‘endure’ through time by ‘being wholly present at more than one time’.1 A related dispute pits ‘presentists’ against ‘non-presentists’. Presentists hold that the only things that really exist are those that exist now, at the present moment; and nonpresentists believe in something like a ‘block-universe’ in which non-simultaneous objects and events nevertheless co-exist (in a tenseless or non-temporal sense). Of late, the relations between these four positions have come under considerable scrutiny.2 As Ned Markosian has pointed out, it would be surprising if commitment to a perdurance or endurance theory of persistence automatically foreclosed one’s options in the presentism—non-presentism debate. But, says Markosian, that is just what the standard formulations of the perdurance and endurance theories imply.3 David Lewis has set the terms of the debate; in his usage, someone who thinks that all persisting objects endure would be said to hold the following.

Property dualism is enjoying a slight resurgence in popularity, these days; substance dualism, not so much. But it is not as easy as one might think to be a property dualist and a substance materialist. The reasons for being a property dualist support the idea that some phenomenal properties (or qualia) are as fundamental as the most basic physical properties; but what material objects could be the bearers of the qualia? If even some qualia require an adverbial construal (if they (...) are modifications of the thing that is conscious because of them, not properties of something else to which the subject of consciousness is related), then the property dualist can be driven to speculative forms of materialism none of which, at this point, looks more likely to be true than the more modest versions of emergent dualism defended by contemporary substance dualists.

Physical boundaries and the earliest topologists. Topology has a relatively short history; but its 19th century roots are embedded in philosophical problems about the nature of extended substances and their boundaries which go back to Zeno and Aristotle. Although it seems that there have always been philosophers interested in these matters, questions about the boundaries of three-dimensional objects were closest to center stage during the later medieval and modern periods. Are the boundaries of an object actually existing, less-than-three-dimensional parts of (...) the object—that is, are solids bounded by two-dimensional surfaces, surfaces by one-dimensional “edges” or “physical lines”, edges by dimensionless “simples”? If not, how does a perfectly spherical object manage to touch a perfectly flat object—what part of the sphere is in immediate contact with the plane, if the sphere has no unextended parts? But if such parts be admitted, are we not then saddled with “actual infinities” of simples, lines, and surfaces spread throughout each continuous object—the boundaries of all the object’s internal parts? Does it help to say that these internal boundaries exist only “potentially”? (shrink)

It is not easy to be a materialist and yet believe that there is a way for human beings to survive death. Peter van Inwagen identifies the central obstacle the materialist faces: Namely, the need to posit appropriate “immanent-causal” connections between my body as it is at death and some living body elsewhere or elsewhen. I offer a proposal, consistent with van Inwagen’s own materialist metaphysics, for making materialism compatible with the possibility of survival.

‘Molinism’, in contemporary usage, is the name for a theory about the workings of divine providence. Its defenders include some of the most prominent contemporary Protestant and Catholic philosophical theologians.¹ Molinism is often said to be the only way to steer a middle..

This book addresses two basic questions: What is the proper philosophical analysis of the concept of substance? and What kinds of compound substances are there? The second question is mainly addressed by asking what relations among objects are necessary and sufficient for their coming to compose a larger whole. The first 72 pages of the book contain a short history of attempts to answer the first question, and a brief presentation of the analysis the authors defend at length in their (...) earlier book, Substance Among Other Categories. In the remaining 119 pages, the authors take up the second question. This order of presentation makes sense; but it may help to create a false impression in those who only glance at the first few pages—that this book is just a simplified version of the earlier one, with a little bit of history thrown in. It would be quite unfortunate, however, if very many potential readers get this impression; for it might discourage them from looking closely at the bulk of the book, which is new. The issues discussed in the later chapters are at the center of one of the most lively debates in contemporary metaphysics; and the position Hoffman and Rosenkrantz stake out is appealing and carefully articulated. Their views deserve careful attention from philosophers working on the metaphysics of persistence through time, personal identity, artifact identity, and mereology. (shrink)

My comments have two parts. I begin by laying out the argument that seems to me to be at the core of Olson’s thinking about human persons; and I suggest a problem with his reasons for accepting one of its premises. The premise is warranted by its platitudinous or commonsensical status; but Olson’s arguments lead him to conclusions that undermine the family of platitudes to which it belongs. Then I’ll raise a question about how Olson should construe the vagueness that (...) would seem to infect the boundaries of human animals. (shrink)

The nature of persons is a perennial topic of debate in philosophy, currently enjoying something of a revival. In this volume for the first time metaphysical debates about the nature of human persons are brought together with related debates in philosophy of religion and theology. Fifteen specially written essays explore idealist, dualist, and materialist views of persons, discuss specifically Christian conceptions of the value of embodiment, and address four central topics in philosophical theology: incarnation, resurrection, original sin, and the trinity.

The most well-known arguments for the simplicity of the soul - i.e., for the thesis that the subject of psychological states must be an unextended substance -are based upon the logical possibility of disembodiment. Descartes introduced this sort of argument into modern philosophy, and a version of it has been defended recently by Richard Swinburne. Some of the underlying assumptions of both arguments are examined and defended, but a closer look reveals that each depends upon unjustified inferences from the conceivability (...) of a certain state of affairs to the logical possibility of that state of affairs.

Oxford Studies in Metaphysics is a major new series dedicated to the timely publication of new work in this highly fertile field of philosophy.

Many theists reject the notion that God’s eternity consists in his timelessness — i.e., in his lacking temporal extension and failing to possess properties at any times. Some of these “divine temporalists” hold that, for philosophical reasons, it is impossible to accept both the timelessness of God and the view that God knows what happens at different times and brings about events in time. 1 Many reject divine timelessness as a dubious import from Platonism with no biblical or theological warrant.2 (...) And some question the very intelligibility of the doctrine. (shrink)

I have argued that contemporary humeans face a trilemma: either (i) give up temporal parts. (ii) deny the humean supervenience of causal relations, or (iii) deny the possibility of there being a difference between rotating and nonrotating homogeneous spheres. Mark Scala (“Homogeneous Simples”, Philosophy and Phenomenological Research, Vol. 64, 2002) describes an interesting class of seemingly possible objects, spinning and stationary simples; and argues their possibility undermines my argument. I argue that it does not. And 1 conclude with a more (...) general assessment of the status of objections to humeanism from the possibility of homogeneous objects in motion. (shrink)

William Rowe argues that if an omnipotent, omniscient being were faced with an infinite hierarchy of better and better worlds to create, that being could not also be unsurpassably morally excellent. His argument assumes that, at least in ideal circumstances, degree of moral goodness must be perfectly expressed in the degree of goodness of the outcomes chosen. Reflection upon the application of analogous expression principles for certainty and desire shows that such principles can be expected to fail for anyone capable (...) of facing an infinite range of options.

I attempt to rebut Dean Zimmerman's novel argument (2010), which he presents in support of substance dualism, for the conclusion that, in spite of its popularity, the combination of property dualism with substance materialism represents a precarious position in the philosophy of mind. I take issue with Zimmerman's contention that the vagueness of 'garden variety' material objects such as brains or bodies makes them unsuitable candidates for the possession of phenomenal properties. I also argue that the 'speculative materialism' that is (...) available to a substance materialist property dualist who abandons the identification of persons with such garden variety objects is significantly more attractive than Zimmerman allows. Although I do not attempt to refute its substance dualist rival, I conclude that the combination of property dualism with substance materialism can withstand Zimmerman's objections. (shrink)

Anyone who wants to know what's happening in metaphysics can start here. Volume Two begins with a major paper on consciousness by Ned Block. Block examines 'Max Black's Objection to Mind-Body Identity', an argument for a dualism of physical and phenomenal properties, closely related to Jackson's 'knowledge argument'. His extensive exploration of this family of arguments for property dualism includes considerable discussion of John Perry and Stephen White; their responses to Block's paper complete the section on the metaphysics of consciousness.Three papers consider the thesis that the future is, in some sense, 'open'. Eli Hirsch elaborates a view according to which contingent statements about the future can be indeterminate in truth-value, while preserving 'straight logic', including a principle of bivalence. Peter Forrest defends a sort of 'growing block' theory of the passage of time, emphasizing the way such a metaphysics, combined with a truth-maker principle, can provide an analysis of natural necessity. Trenton Merricks presents a trenchant and original criticism of the 'growing block' theory of time.The volume continues with a group of papers on problems of ontology. Thomas Hofweber's paper, defending nominalism from the objection that there are 'inexpressible' properties and propositions, won the first annual Oxford Studies in Metaphysics Younger Scholar Prize. The papers by Phillip Bricker and Michael Loux examine a couple of deep divides within ontology. John Hawthorne's paper raises some extremely puzzling questions about the nature of persons, given the ontology needed for Timothy Williamson's theory of vagueness. Hawthorne uses these problems to motivate an alternative style of epistemicism. The final three papers take up several issues in the metaphysics of traditional theism. Michael Bergmann and Jeffrey Brower raise objections to combining a Platonic conception of universals with the doctrine of divine aseity; while Brian Leftow defends a non-Platonic theory of universals - a kind of divine-concept nominalism. Hud Hudson suggests that contemplation of the possibility of higher dimensions opens up new avenues in theodicy. (shrink)
