A variety of relations widely invoked by philosophers—composition, constitution, realization, micro-basing, emergence, and many others—are species of what I call ‘building relations’. I argue that they are conceptually intertwined, articulate what it takes for a relation to count as a building relation, and argue that—contra appearances—it is an open possibility that these relations are all determinates of a common determinable, or even that there is really only one building relation.

What are the ontological commitments of a sentence? In this paper I offer an answer from the perspective of the truthmaker theorist that contrasts with the familiar Quinean criterion. I detail some of the benefits of thinking of things this way: they include making the composition debate tractable without appealing to a neo-Carnapian metaontology, making sense of neo-Fregeanism, and dispensing with some otherwise recalcitrant necessary connections.

There is a well-known argument from Leibniz's Law for the view that coincident material things may be distinct. For given that they differ in their properties, then how can they be the same? However, many philosophers have suggested that this apparent difference in properties is the product of a linguistic illusion; there is just one thing out there, but different sorts or guises under which it may be described. I attempt to show that this ‘opacity’ defence has intolerable consequences for (...) the functioning of our language and that the original argument should therefore be allowed to stand. (shrink)

This article offers a novel, conservative account of material constitution, one that incorporates sortal essentialism and features a theory of dominant sortals. It avoids coinciding objects, temporal parts, relativizations of identity, mereological essentialism, anti-essentialism, denials of the reality of the objects of our ordinary ontology, and other departures from the metaphysic implicit in ordinary ways of thinking. Defenses of the account against important objections are found in Burke 1997, 2003, and 2004, as well as in the often neglected six paragraphs (...) that conclude section V of this article. (shrink)

A lot of people believe that distinct objects can occupy precisely the same place for the entire time during which they exist. Such people have to provide an answer to the 'grounding problem' – they have to explain how such things, alike in so many ways, nonetheless manage to fall under different sortals, or have different modal properties. I argue in detail that they cannot say that there is anything in virtue of which spatio-temporally coincident things have those properties. However, (...) I also argue that this may not be as bad as it looks, and that there is a way to make sense of the claim that such properties are primitive. (shrink)

The properties colored and red stand in a special relation. Namely, red is a determinate of colored, and colored is determinable relative to red. Many other properties are similarly related. The determination relation is an interesting topic of logical investigation in its own right, and the prominent philosophical inquiries into this relation have, accordingly, operated at a high level of abstraction.1 It is time to return to these investigations, not just as a logical amusement, but for the payoffs such investigation (...) can yield in solving some basic metaphysical problems. The goal in what follows is twofold. First, I argue for a novel understanding of the determination relation. Second, this understanding is applied to yield insights into property instance (e.g., trope) individuation, how different property types can share an instance, the relation between property types and property instances, as well as applications to causation (mental causation, in particular).

Mereological nihilism is the thesis that composite objects—objects with proper parts—do not exist. Nihilists generally paraphrase talk of composite objects F into talk of there being “xs arranged F-wise” . Recently several philosophers have argued that nihilism is defective insofar as nihilists are either unable to say what they mean by such phrases as “there are xs arranged F-wise,” or that nihilists are unable to employ such phrases without incurring significant costs, perhaps even undermining one of the chief motivations for (...) nihilism. In this paper I defend nihilism against these objections. A key theme of the paper is this: if nihilists need to employ such phrases as “there are xs arranged F-wise,” non-nihilists will need to do so as well. Accordingly, any costs incurred by the nihilist when she employs such phrases will be shared by everyone else. What’s more, such phrases are intelligible when employed by the nihilist, as well as when they are employed by the non-nihilist, insofar as analyses of such phrases will not essentially involve mereological concepts incompatible with nihilism.

Mereological nihilism is the thesis that composition never occurs. Some philosophers have thought that science gives us compelling evidence against nihilism. In this article I respond to this concern. An initial challenge for nihilism stems from the fact that composition is such a ubiquitous feature of scientific theories. In response I motivate a restricted form of scientific anti-realism with respect to those components of scientific theories which make reference to composition. A second scientifically based worry for nihilism is that certain (...) specific scientific phenomena might require ineliminable quantification over composite objects. I address these concerns, and argue that there seem to be nihilist-friendly construals of the scientific phenomena in question. (shrink)

In his interesting article 'Constitution is not Identity' (1992), Mark Johnston argues that (in a sense soon to be explained) constitution is distinct from identity. In what follows, I dispute Johnston's contention.

It is often said that the same particles can simultaneously make up two or more material objects that differ in kind and in their mental, biological, and other qualitative properties. Others wonder how objects made of the same parts in the same arrangement and surroundings could differ in these ways. I clarify this worry and show that attempts to dismiss or solve it miss its point. At most one can argue that it is a problem we can live with.

A bronze statue is a lump of bronze – or so it might appear. But appearances are not always to be trusted, and this one is notoriously problematic. To see why, imagine a bronze statue (perhaps a statue of David) and ask yourself: Which lump of bronze is the statue? Presumably, it is the lump that makes up the statue (or, as we say, the lump that constitutes the statue). After all, why should the statue be any other lump of (...) bronze? But if that is right, if the statue is the lump of bronze that constitutes it, then why can the lump of bronze survive being melted down whereas the statue it constitutes cannot? It seems that in fact the bronze statue is not the lump of bronze that constitutes it, since the statue and the lump of bronze have different persistence conditions. But then is it some other lump of bronze? Is it a lump of bronze at all? These questions are troubling; they appear to have no easy answers. (shrink)

What is the relation between a clay statue andthe lump of clay from which it is made? According to the defender of the standardaccount, the statue and the lump are distinct,enduring objects that share the same spatiallocation whenever they both exist. Suchobjects also seem to share the samemicrophysical structure whenever they bothexist. This leads to the standard objection tothe standard account: if the statue and thelump of clay have the same microphysicalstructure whenever they both exist, how canthey differ in their (...) de re temporalproperties, de re modal properties and soon? In this paper I develop amereological answer to this question – thestatue and the lump differ with respect totheir parts and this explains theirdifference with respect to de re temporalproperties, de re modal properties andthe like.

Mereological nihilism is the thesis that there are no composite objects—i.e. objects with proper material parts. One of the main advantages of mereological nihilism is that it allows its supporters to avoid a number of notorious philosophical puzzles. However, it seems to offer this advantage only at the expense of certain widespread and deeply entrenched beliefs. In particular, it is usually assumed that mereological nihilism entails eliminativism about ordinary objects—i.e. the counterintuitive thesis that there are no such things as tables, (...) apples, cats, and the like. In this paper, I argue that this assumption is false—mereological nihilists do not need to be eliminativists about tables, apples, or cats. Non-eliminativist nihilists claim that all it takes for there to be a cat is that there are simples arranged cat-wise. More specifically, non-eliminative nihilists argue that expressions such as ‘the cat’ in sentences such as ‘The cat is on the mat’ do not refer to composite objects but only to simples arranged cat-wise and compare this metaphysical discovery to the scientific discovery that ‘water’ refers to dihydrogen oxide. Non-eliminative nihilism, I argue, is not only a coherent position, but it is preferable to its more popular, eliminativist counterpart, as it enjoys the key benefits of nihilism without incurring the prohibitive costs of eliminativism. Moreover, unlike conciliatory strategies adopted by eliminative nihilists, non-eliminative nihilism allow its supporters to account not only for how we can assert something true by saying ‘The cat is on the mat’ but also for how we can believe something true by believing that the cat is on the mat.

Monists about material constitution typically argue that when Statue is materially constituted by Clay, Statue is just Clay. Pluralists about material constitution deny that constitution is identity: Statue is not just Clay. When Clay materially constitutes Statue, Clay is not identical to Statue. I discuss three familiar puzzles involving grounding, overdetermination and conceptual issues, and develop three new puzzles stemming from the connection between mereological composition and material constitution: a mereological puzzle, an asymmetry puzzle, and a structural puzzle.

Are the sculpture and the mass of gold which permanently makes it up one object or two? In this article, we argue that the monist, who answers ‘one object’, cannot accommodate the asymmetry of material constitution. To say ‘the mass of gold materially constitutes the sculpture, whereas the sculpture does not materially constitute the mass of gold’, the monist must treat ‘materially constitutes’ as an Abelardian predicate, whose denotation is sensitive to the linguistic context in which it appears. We motivate (...) this approach in terms of modal analyses of material constitution, but argue that ultimately it fails. The monist must instead accept a deflationary, symmetrical use of ‘materially constitutes’. We argue that this is a serious cost for her approach. (shrink)

I have both a smaller and a larger aim. The smaller aim is polemical. Kit Fine believes that a material thing—a Romanesque statue, for example, or an open door—can be distinguished from its constituent matter—a piece of alloy, say, or a hunk of plastic—without recourse to modal or temporal considerations. The statue is Romanesque; the piece of alloy is not Romanesque. The door is open; the hunk of plastic is not open. I argue that these considerations, when combined with a (...) proper understanding of how the use of ‘not’ is functioning, entail that the statue is the piece of alloy, and that the door is the hunk of plastic. Far from challenging the doctrine that a material thing is its matter, Fine’s observations confirm the view. My larger aim is methodological. I will show that natural language semantics can guide inquiry in certain areas of metaphysics by helping us to advance lingering debates. (shrink)

Yablo suggests that we can understand the possibility of mental causation by supposing that mental properties determine physical properties, in the classic sense of determination according to which red determines scarlet. Determinates and their determinables do not compete for causal relevance, so if mental and physical properties are related as determinable and determinates, they should not compete for causal relevance either. I argue that this solution won''t work. I first construct a more adequate account of determination than that provided by (...) Yablo. I then consider two common accounts of the mental, token identity theories and dispositional theories, and argue that on neither do mental and physical properties satisfy the requirements for determination.
