The general account of material constitution presented in my article, Spatially Coinciding Objects (Ratio vol. 24.1, June 1982), is further developed. There we saw how distinct objects in the same place at the same time can be strictly ordered by an asymmetrical, transitive relation of material constitution. I show herein how this relation can conceivably form ‘upright trees’ in which one object constitutes two other objects, neither of which constitutes the other. It is, however, impossible to have ‘inverted trees’ in (...) which one thing is constituted by two things neither of which constitutes the other. (This impossibility is implied when supposing that there is just one thing which counts as the proximate matter of a thing.). (shrink)

Consider a cat on a mat. On the one hand, there seems to be just one cat, but on the other there seem to be many things with as good a claim as anything in the vicinity to being a cat. Hence, the problem of the many. In his ‘Many, but Almost One,’ David Lewis offered two solutions. According to the first, only one of the many is indeed a cat, although it is indeterminate exactly which one. According to the (...) second, the many are all cats, but they are almost identical to each other, and hence they are almost one. For Lewis, the two solutions do not compete with each other but are mutually complementary, as each one can assist the other. This paper has two aims: to give some reasons against the first of these two solutions, but then to defend the second as a self-standing solution from Lewis’s considerations to the contrary.

Many significant problems in metaphysics are tied to ontological questions, but ontology and its relation to larger questions in metaphysics give rise to a series of puzzles that suggest that we don't fully understand what ontology is supposed to do, nor what ambitions metaphysics can have for finding out about what the world is like. Thomas Hofweber aims to solve these puzzles about ontology and consequently to make progress on four metaphysical debates tied to ontology: the philosophy of arithmetic, the (...) metaphysics of ordinary objects, the problem of universals, and the question of whether the fact-like aspect of reality is independent of us. Crucial parts of the proposed solution involve considerations about quantification and its relationship to ontology, the place of reference in natural languages, the relationship between syntactic form and focus, whether there could be any ineffable facts, and others.

Simon J. Evnine explores the view that some objects have matter from which they are distinct but that this distinctness is not due to the existence of anything like a form. He draws on Aristotle's insight that such objects must be understood in terms of an account that links what they are essentially with how they come to exist and what their functions are. Artifacts are the most prominent kind of objects where these three features coincide, and Evnine develops a (...) detailed account of the existence and identity conditions of artifacts, and the origins of their functions, in terms of how they come into existence. He then extends this account to organisms, where evolution accomplishes what is effected by intentional making in the case of artifacts, and to actions, which are seen as artifactual events.

This is a book about the concept of a physical thing and about how the names of things relate to the things they name. It questions the prevalent view that names 'refer to' or 'denote' the things they name. Instead it presents a new theory of proper names, according to which names express certain special properties that the things they name exhibit. This theory leads to some important conclusions about whether things have any of their properties as a matter of (...) necessity. This will be an important book for philosophers in metaphysics and the philosophy of language, though it will also interest linguists concerned with the semantics of natural language. (shrink)

Hilary Putnam deals in this book with some of the most fundamental persistent problems in philosophy: the nature of truth, knowledge and rationality. His aim is to break down the fixed categories of thought which have always appeared to define and constrain the permissible solutions to these problems.

One of the central questions of material-object metaphysics is which highly visible objects there are right before our eyes. Daniel Z. Korman defends a conservative view, according to which our ordinary, natural judgments about which objects there are are more or less correct. He begins with an overview of the arguments that have led people away from the conservative view, into revisionary views according to which there are far more objects than we ordinarily take there to be or far fewer. (...) Korman criticizes a variety of compatibilist strategies, according to which these revisionary views are actually compatible with our ordinary beliefs. He goes on to respond to debunking arguments; objections that the conservative's verdicts about which objects that are and aren't are objectionably arbitrary; the argument from vagueness; the overdetermination argument; the argument from material constitution; and the problem of the many.

Philosophical naturalism, according to which philosophy is continuous with the natural sciences, has dominated the Western academy for well over a century; but Michael Rea claims that it is without rational foundation, and that the costs of embracing it are surprisingly high. The first part of World Without Design aims to provide a fair and historically informed characterization of naturalism. Rea then argues compellingly to the surprising conclusion that naturalists are committed to rejecting realism about material objects, materialism, and perhaps (...) realism about other minds. This conclusion is striking, largely because naturalism is often simply identified with materialism, and the remaining two theses are ones that naturalists very typically want to endorse. Rea goes on to examine two alternative research programs: intuitionism and supernaturalism, and argues for the conclusion that intuitionism, under certain circumstances, is self-defeating.World Without Design offers a provocative challenge to philosophical orthodoxy. It will make uncomfortable reading for many philosophers. (shrink)

Thomas Sattig develops a novel philosophical picture of ordinary objects such as persons, tables, and trees. He carves a middle way between classical mereology and Aristotelian hylomorphism, and argues that objects lead double lives. They are compounds of matter and form, and each object's matter and form have different qualitative profiles.

John Hawthorne is widely regarded as one of the finest philosophers working today. He is perhaps best known for his contributions to metaphysics, and this volume collects his most notable papers in this field. Hawthorne offers original treatments of fundamental topics in philosophy, including identity, ontology, vagueness, and causation. Six of the essays appear here for the first time, and there is a valuable introduction to guide the reader through the selection.

I argue that from a very weak recombination principle and plausible assumptions about the nature of parthood and location it follows that it's possible that the mereological structure of the material world and that of spacetime fail to correspond to one another in very radical ways. I defend, moreover, that rejecting the possibility of such failures of correspondence leaves us with a choice of equally radical alternatives. I also discuss a few ways in which their possibility is relevant to various (...) debates in metaphysics. (shrink)

Existence questions have been topics for heated debates in metaphysics, but this book argues that they can often be answered easily, by trivial inferences from uncontroversial premises. This 'easy' approach to ontology leads to realism about disputed entities, and to the view that metaphysical disputes about existence questions are misguided.

Boris Kment takes a new approach to the study of modality that emphasises the origin of modal notions in everyday thought. He argues that the concepts of necessity and possibility originate in counterfactual reasoning, which allows us to investigate explanatory connections. Contrary to accepted views, explanation is more fundamental than modality.

Steven French articulates and defends the bold claim that there are no objects in the world. He draws on metaphysics and philosophy of science to argue for structural realism--the position that we live in a world of structures--and defends a form of eliminativism about objects that sets laws and symmetry principles at the heart of ontology.

A provocative ontological-cum-semantic position asserting that the right ontology is austere in its exclusion of numerous common-sense and scientific posits and that many statements employing such posits are nonetheless true. The authors of Austere Realism describe and defend a provocative ontological-cum-semantic position, asserting that the right ontology is minimal or austere, in that it excludes numerous common-sense posits, and that statements employing such posits are nonetheless true, when truth is understood to be semantic correctness under contextually operative semantic standards. Terence (...) Horgan and Matjaz Potrc argue that austere realism emerges naturally from consideration of the deep problems within the naive common-sense approach to truth and ontology. They offer an account of truth that confronts these deep internal problems and is independently plausible: contextual semantics, which asserts that truth is semantically correct affirmability. Under contextual semantics, much ordinary and scientific thought and discourse is true because its truth is indirect correspondence to the world. After offering further arguments for austere realism and addressing objections to it, Horgan and Potrc consider various alternative austere ontologies. They advance a specific version they call "blobjectivism"--the view that the right ontology includes only one concrete particular, the entire cosmos, which, although it has enormous local spatiotemporal variability, does not have any proper parts. The arguments in Austere Realism are powerfully made and concisely and lucidly set out. The authors' contentions and their methodological approach--products of a decade-long collaboration--will generate lively debate among scholars in metaphysics, ontology, and philosophy. (shrink)

This collection of essays is the first of its kind to focus on the relationship between composition and identity. Twelve original articles--written by internationally renowned scholars and rising stars in the field--argue for and against the controversial doctrine that composition is identity.--Provided by publisher.

Moral thinking pervades our practical lives, but where did this way of thinking come from, and what purpose does it serve? Is it to be explained by environmental pressures on our ancestors a million years ago, or is it a cultural invention of more recent origin? In The Evolution of Morality, Richard Joyce takes up these controversial questions, finding that the evidence supports an innate basis to human morality. As a moral philosopher, Joyce is interested in whether any implications follow (...) from this hypothesis. Might the fact that the human brain has been biologically prepared by natural selection to engage in moral judgment serve in some sense to vindicate this way of thinking--staving off the threat of moral skepticism, or even undergirding some version of moral realism? Or if morality has an adaptive explanation in genetic terms--if it is, as Joyce writes, "just something that helped our ancestors make more babies"--might such an explanation actually undermine morality's central role in our lives? He carefully examines both the evolutionary "vindication of morality" and the evolutionary "debunking of morality," considering the skeptical view more seriously than have others who have treated the subject.Interdisciplinary and combining the latest results from the empirical sciences with philosophical discussion, The Evolution of Morality is one of the few books in this area written from the perspective of moral philosophy. Concise and without technical jargon, the arguments are rigorous but accessible to readers from different academic backgrounds. Joyce discusses complex issues in plain language while advocating subtle and sometimes radical views. The Evolution of Morality lays the philosophical foundations for further research into the biological understanding of human morality. (shrink)

Most contemporary metaphysicians are sceptical about the reality of familiar objects such as dogs and trees, people and desks, cells and stars. They prefer an ontology of the spatially tiny or temporally tiny. Tiny microparticles 'dog-wise arranged' explain the appearance, they say, that there are dogs; microparticles obeying microphysics collectively cause anything that a baseball appears to cause; temporal stages collectively sustain the illusion of enduring objects that persist across changes. Crawford L. Elder argues that all such attempts to 'explain (...) away' familiar objects project downwards, onto the tiny entities, structures and features of familiar objects themselves. He contends that sceptical metaphysicians are thus employing shadows of familiar objects, while denying that the entities which cast those shadows really exist. He argues that the shadows are indeed really there, because their sources - familiar objects - are mind-independently real. (shrink)

This bold and original work of philosophy presents an exciting new picture of concrete reality. Peter Unger provocatively breaks with what he terms the conservatism of present-day philosophy, and returns to central themes from Descartes, Locke, Berkeley, Hume and Russell. Wiping the slate clean, Unger works, from the ground up, to formulate a new metaphysic capable of accommodating our distinctly human perspective. He proposes a world with inherently powerful particulars of two basic sorts: one mental but not physical, the other (...) physical but not mental. Whether of one sort or the other, each individual possesses powers for determining his or her own course, as well as powers for interaction with other individuals. It is only a purely mental particular--an immaterial soul, like yourself--that is ever fit for real choosing, or for conscious experiencing. Rigorously reasoning that the only satisfactory metaphysic is one that situates the physical alongside the non-physical, Unger carefully explains the genesis of, and continual interaction of, the two sides of our deeply dualistic world. Written in an accessible and entertaining style, while advancing philosophical scholarship, All the Power in the World takes readers on a philosophical journey into the nature of reality. In this riveting intellectual adventure, Unger reveals the need for an entirely novel approach to the nature of physical reality--and shows how this approach can lead to wholly unexpected possibilities, including disembodied human existence for billions of years. All the Power in the World returns philosophy to its most ambitious roots in its fearless attempt to answer profoundly difficult human questions about ourselves and our world. (shrink)

Plural predication is a pervasive part of ordinary language. We can say that some people are fifty in number, are surrounding a building, come from many countries, and are classmates. These predicates can be true of some people without being true of any one of them; they are non-distributive predications. However, the apparatus of modern logic does not allow a place for them. Thomas McKay here explores the enrichment of logic with non-distributive plural predication and quantification. His book will be (...) of great interest to philosophers of language, linguists, metaphysicians, and logicians. (shrink)

The objects we encounter in ordinary life and scientific practice - cars, trees, people, houses, molecules, galaxies, and the like - have long been a fruitful source of perplexity for metaphysicians. The Structure of Objects gives an original analysis of those material objects to which we take ourselves to be committed in our ordinary, scientifically informed discourse. Koslicki focuses on material objects in particular, or, as metaphysicians like to call them "concrete particulars", i.e., objects which occupy a single region of (...) space-time at each time at which they exist and which have a certain range of properties that go along with space-occupancy, such as weight, shape, color, texture, and temperature. The Structure of Objects focuses in particular on the question of how the parts of such objects, assuming that they have parts, are related to the wholes which they compose. (shrink)

In this book Jonathan Lowe offers a lucid and wide-ranging introduction to the philosophy of mind. Using a problem-centred approach designed to stimulate as well as instruct, he begins with a general examination of the mind-body problem and moves on to detailed examination of more specific philosophical issues concerning sensation, perception, thought and language, rationality, artificial intelligence, action, personal identity and self-knowledge. His discussion is notably broad in scope, and distinctive in giving equal attention to deep metaphysical questions concerning the (...) mind and to the discoveries and theories of modern scientific psychology. It will be of interest to any reader with a basic grounding in modern philosophy. (shrink)

This anthology, intended to accompany _A Companion to Metaphysics_, brings together over 60 selections which represent the best and most important works in metaphysics during this century. The selections are grouped under ten major metaphysical problems and each section is preceded by an introduction by the editors.

Thomas Holden presents a fascinating study of theories of matter in the seventeenth and eighteenth centuries. These theories were plagued by a complex of interrelated problems concerning matter's divisibility, composition, and internal architecture. Is any material body infinitely divisible? Must we posit atoms or elemental minima from which bodies are ultimately composed? Are the parts of material bodies themselves material concreta? Or are they merely potentialities or possible existents? Questions such as these -- and the press of subtler questions hidden (...) in their amibiguities -- deeply unsettled philosophers of the early modern period. They seemed to expose serious paradoxes in the new world view pioneered by Galileo, Descartes, and Newton. The new science's account of a fundamentally geometrical Creation, mathematicizable and intelligible to the human inquirer, seemed to be under threat. This was a great scandal, and the philosophers of the period accordingly made various attempts to disarm the paradoxes. All the great figures address the issue: most famously Leibniz and Kant, but also Galileo, Hobbes, Newton, Hume, and Reid, in addition to a crowd of lesser figures. Thomas Holden offers a brilliant synthesis of these discussions and presents his own overarching interpretation of the controversy, locating the underlying problem in the tension between the early moderns' account of material parts on the one hand and the program of the geometrization of nature on the other.

Substance has been a leading idea in the history of Western philosophy. _Joshua Hoffman and Gary S. Rosenkrantz_ explain the nature and existence of individual substances, including both living things and inanimate objects. Specifically written for students new to this important and often complex subject, _Substance_ provides both the historical and contemporary overview of the debate. Great Philosophers of the past, such as Aristotle, Descartes, Spinoza, Leibnitz, Locke, and Berkeley were profoundly interested in the concept of substance. And, the authors (...) argue, a belief in the existence of substances is an integral part of our everyday world view. But what constitutes substance? Was Aristotle right to suggest that artefacts like tables and ships don't really exist? _Substance: Its Nature and Existence_ is one of the first non-technical, accessible guides to this central problem and will be of great use to students of metaphysics and philosophy.

This provocative book attempts to resolve traditional problems of identity over time. It seeks to answer such questions as 'How is it that an object can survive change?' and 'How much change can an object undergo without being destroyed'? To answer these questions Professor Heller presents a theory about the nature of physical objects and about the relationship between our language and the physical world. According to his theory, the only actually existing physical entities are what the author calls 'hunks', (...) four-dimensional objects extending across time and space. This is a major contribution to ontological debate and will be essential reading for all philosophers concerned with metaphysics. (shrink)

This book is an investigation into metaphysics: its aims, scope, methodology and practice. Dyke argues that metaphysics should take itself to be concerned with investigating the fundamental nature of reality, and suggests that the ontological significance of language has been grossly exaggerated in the pursuit of that aim.

The only anthology available on material constitution, this book collects important recent work on well known puzzles in metaphysics and philosophy of mind. The extensive, clearly written introduction helps to make the essays accessible to a wide audience.

Lynne Rudder Baker presents and defends a unique account of the material world: the Constitution View. In contrast to leading metaphysical views that take everyday things to be either non-existent or reducible to micro-objects, the Constitution View construes familiar things as irreducible parts of reality. Although they are ultimately constituted by microphysical particles, everyday objects are neither identical to, nor reducible to, the aggregates of microphysical particles that constitute them. The result is genuine ontological diversity: people, bacteria, donkeys, mountains and (...) microscopes are fundamentally different kinds of things - all constituted by, but not identical to, aggregates of particles. Baker supports her account with discussions of non-reductive causation, vagueness, mereology, artefacts, three-dimensionalism, ontological novelty, ontological levels and emergence. The upshot is a unified ontological theory of the entire material world that irreducibly contains people, as well as non-human living things and inanimate objects. (shrink)

On the now dominant Quinean view, metaphysics is about what there is. Metaphysics so conceived is concerned with such questions as whether properties exist, whether meanings exist, and whether numbers exist. I will argue for the revival of a more traditional Aristotelian view, on which metaphysics is about what grounds what. Metaphysics so revived does not bother asking whether properties, meanings, and numbers exist (of course they do!) The question is whether or not they are fundamental.

Debunking arguments are arguments that aim to undermine some range of beliefs by showing that those beliefs are not appropriately connected to their subject matter. Arguments of this sort rear their heads in a wide variety of domains, threatening beliefs about morality, mathematics, logic, color, and the existence of God. Perceptual beliefs about ordinary objects, however, are widely thought to be invulnerable to such arguments. I will show that this is a mistake. I articulate a debunking argument that purports to (...) undermine our most basic perceptual beliefs. I then challenge a number of responses to the argument, including the “permissivist” response that there are a plenitude of objects before us, virtually guaranteeing the accuracy of our object beliefs. (shrink)

Eleaticism ties ontology to causality by denying the impossibility of causally inert entities. This paper examines some challenges regarding the proper formulation and general plausibility of Eleaticism. After suggesting how Eleatics ought to respond to these challenges, I consider the prospects for extending Eleaticism from ontology to ideology by requiring all primitive ideology to be causal in nature. Surprisingly enough, the resulting view delivers an eternalist and possibilist metaphysical picture in the neighborhood of Lewisian modal realism.

Pluralists about coincident entities say that distinct entities may be spatially coincident throughout their entire existence. The most pressing issue they face is the grounding problem. They say that coincident entities may differ in their persistence conditions and in the sortals they fall under. But how can they differ in these ways, given that they share all their microphysical properties? What grounds those differences, if not their microphysical properties? Do those differences depend only on the way we conceptualise those objects? (...) Are they primitive facts about reality? Neither option is pleasant for the pluralist, but what else can she say? To respond to the grounding problem, the pluralist should first tell a story about what material objects are. If that story explains how the modal and sortal properties of objects are grounded, in a way that allows for differences between coincident objects, then she has a response to the problem. That is precisely my aim in this paper. (shrink)

Evolutionary debunking arguments abound, but it is widely assumed that they do not arise for our perceptual beliefs about midsized objects, insofar as the adaptive value of our object beliefs cannot be explained without reference to the objects themselves. I argue that this is a mistake. Just as with moral beliefs, the adaptive value of our object beliefs can be explained without assuming that the beliefs are accurate. I then explore the prospects for other sorts of vindications of our object (...) beliefs—which involve “bootstrapping” from our experiences as of midsized objects—and I defend bootstrapping maneuvers against a variety of objections. Finally, I argue for an explanatory constraint on legitimate bootstrapping and show how some attempts to respond to debunking arguments run afoul of the constraint. (shrink)

draft, forthcoming Chalmers, Manley and Wasserman eds., Metametaphysics.

I develop and defend a novel answer to Peter van Inwagen’s ‘Special Composition Question,’ (SCQ) namely, under what conditions do some things compose and object? My answer is that things will compose an object when and only when they exist simultaneously relative to a reference frame (I call this ‘Temporally Restricted Composition’ or TREC). I then show how this view wards off objections given to ‘Unrestricted Mereology’ (UM). TREC, unlike other theories of Restricted Composition, does not fall prey to worries (...) about vagueness, anthropocentrism, or arbitrariness. TREC also has advantages over all the other answers to the SCQ. TREC is an account an A-theorist anti-Eternalist who wants an unrestricted mereology should accept. I also engage in some conceptual hygiene by showing how UM, as it should be used, should not, in itself, entail or contain a commitment to either Eternalism or Four-Dimensionalism. (shrink)

There are various puzzles that set our intuitions about composition and identity against one another. Four that are particularly well known are the Growing Argument, the Ship of Theseus Puzzle, the Body-minus Argument, and Allan Gibbard’s puzzle about Lumpl and Goliath. Such puzzles have received a great deal of attention in the literature over the past thirty years, and there is an impressive and growing variety of solutions available for each of them. Surprisingly, however, no one has really discussed how (...) all of the different puzzles, and their solutions, are interrelated. On the surface, they seem to raise different problems; but clearly the puzzles are related somehow. They raise similar questions and generate similar sets of possible solutions. But, as yet, nothing has been said about how far the similarities extend. (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)

We can describe languages in which no words refer to objects. Such languages may contain sentences equivalent to any sentences of English, and hence may allow for as much objectivity as English does. It is wrong to try to deal with such languages by claiming that there are more objects than those accepted by common sense ontology. The correct move is rather to acknowledge a sense in which the concept of an object might have been different. A consequence of this (...) position is that we cannot have a general semantics applicable to every describable language in which words are referentially connected to objects. The point here is not that reference may be inscrutable, but that different concepts of ‘referring to an object’ may be required for different languages. (shrink)

ONE KIND OF PHILOSOPHICAL PUZZLEMENT arises when we have an apparent conflict of intuitions. If we are philosophers, we then try to show that the apparent conflict of intuitions is only an apparent conflict and not a real one. If we fail, we may have to say that what we took to be an apparent conflict of intuitions was in fact a conflict of apparent intuitions, and then we must decide which of the conflicting apparent intuitions is only an apparent (...) intuition. But if we succeed, then both of the intuitions will be preserved. Since there was an apparent conflict, we will have to conclude that the formulation of at least one of the intuitions was defective. And though the formulation may be imbedded in our ordinary language, we will have to say that, strictly and philosophically, a different formulation is to be preferred. But to make it clear that we are not rejecting the intuition we are reformulating, we must show systematically how to interpret the ordinary formulation into the philosophical one. The extent to which we can show this will be one mark of our success in dealing with the philosophical puzzle. Another will be the extent to which our proposed solution contributes to the solution of still other philosophical puzzles. (shrink)

(1) Abstract objects. The nominalist (as the label is used today) denies that there exist abstract objects. The platonist holds that there are abstract objects. One example is numbers. The nominalist denies that there are numbers; the platonist typically affirms it.
