Trope theory is the view that the world is a world of abstract particular qualities. But if all there is are tropes, how do we account for the truth of propositions ostensibly made true by some concrete particular? A common answer is that concrete particulars are nothing but tropes in compresence. This answer seems vulnerable to an argument (first presented by F. H. Bradley) according to which any attempt to account for the nature of relations will end up either in (...) contradiction, nonsense, or will lead to a vicious infinite regress. I investigate Bradley’s argument and claim that it fails to prove what it sets out to. It fails, I argue, because it does not take all the different ways in which relation and relata may depend on one another into account. If relations are entities that are distinct from yet essentially dependent upon their relata, the Bradleyan problem is solved. We are then free to say that tropes in compresence are what make true propositions ostensibly made true by concrete particulars. (shrink)

Material objects extend through space by having different spatial parts in different places. But how do they persist through time? According to some philosophers, things have temporal parts as well as spatial parts: accepting this is supposed to help us solve a whole bunch of metaphysical problems, and keep our philosophy in line with modern physics. Other philosophers disagree, arguing that neither metaphysics nor physics give us good reason to believe in temporal parts.

In this article I examine the compatibility of a leading trope bundle theory of substance, so-called Nuclear Theory, with trope theory more generally. Peter Simons (1994) originally proposed Nuclear Theory (NT), and continues to develop (1998, 2000) and maintain (2002/03) the view. Recently, building on Simons’s theory, Markku Keinänen (2011) has proposed what he calls the Strong Nuclear Theory (SNT). Although the latter is supposed to shore up some of NT’s weaknesses, it continues to maintain NT’s central tenet, the premise (...) that tropes are variously existentially interdependent. I argue that the central tenet of NT frustrates several important aims of trope theory. If my arguments go through, they also implicate SNT. Because of this, I largely set aside other aspects of NT and SNT and focus on their shared central tenet. (shrink)

In this dissertation I consider the merits of certain nominalist accounts of phenomena related to the character of ordinary objects. What these accounts have in common is the fact that none of them is an error theory about standard cases of predication and none of them deploys God or uniquely theistic resources in its explanatory framework. -/- The aim of the dissertation is to answer the following questions: -/- • What is the best nominalist account on offer? • How might (...) it be improved? • Does it ultimately succeed? -/- I will argue that while so-called trope theory is the best account on offer, it can be significantly improved—or replaced—by a novel version of nominalism that is modeled after trope theory. Ultimately, however, I will argue that even the novel version fails. -/- The dissertation unfolds as follows. In Chapter 1, I introduce Austere Nominalism (AN), which is perhaps the most extreme version of nominalism that falls within the scope of the dissertation. AN is often described as the view that there exist only concrete particulars. According to AN, it is unnecessary to posit any entities other than ordinary objects—turkeys, tables, and the like—in order to account for explananda related to the character of those objects. (Such explananda include the phenomenon of attribute agreement, of attribute possession, of true subject-predicate sentences, etc.) In this chapter I argue that AN fails to provide an adequate account of these explananda. In addition, introducing and criticizing AN serves an important heuristic role for the rest of the dissertation. To understand this role, we must distinguish between the basic explanatory strategy deployed by the austere nominalist and the type of explananda for which she deploys that strategy. The austere nominalist deploys the strategy to account for the character of ordinary objects. As I argue in Chapter 1, this deployment is a failure. As I go on to show in Chapter 2, the widespread rejection AN has led to a variety of rival accounts of the character of ordinary objects. In rejecting AN, however, these accounts also tacitly reject its basic explanatory strategy. Thus goes the baby with the bathwater, since, arguably, there are some attractive features of AN’s basic explanatory strategy. Indeed, those who defend the most prominent version of nominalism—trope theory—seem to overlook the advantages of AN’s basic strategy, and by so doing, make an unnecessary concession to the realist. Or so I argue in Chapter 3. And, as I will argue in Chapter 4, the strongest version of nominalism is a novel account, modeled after trope theory, that deploys AN’s basic strategy at a more fundamental level than that of ordinary objects. This novel account—troper theory—is closer in spirit to AN than is traditional trope theory. (Thus, AN serves as a foil for the discussion of other nominalist views.) Finally, in the Afterword I indicate how troper theory is equally vulnerable to some of the traditional objections that plague trope theory. Thus, if you are not convinced that traditional objections to trope theory are conclusive and you want to be a nominalist, then you should abandon trope theory and adopt troper theory. If you take traditional objections against trope theory to have significant force, then you should reject both theories. (shrink)

My aim in this article is to contribute to the larger project of assessing the relative merits of different theories of substance. An important preliminary step in this project is assessing the explanatory resources of one main theory of substance, the so-called bundle theory. This article works towards such an assessment. I identify and explain three distinct explanatory challenges an adequate bundle theory must meet. Each points to a putative explanatory gap, so I call them the Gap Challenges. I consider (...) three bundle-theoretic strategies for meeting these challenges. I argue that none of them goes very far. The upshot is that, absent other strategies for meeting the challenges, bundle theory involves a significant amount of stipulation. This black box makes bundle theory relatively weak with respect to its explanatory power—unless, of course, rival theories of substance are unable to do better. (shrink)

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.

In this chapter, we provide an opinionated introduction to contemporary trope bundle theories of substance. We assess different trope bundle theories on the grounds of their two main aims: to provide an adequate account of substances or objects by means of tropes and a reductive analysis of inherence, that is, object's having tropes as their properties. Our discussion begins by a presentation of Donald C. Williams’ and Keith Campbell's paradigmatic trope theories, which maintain that tropes are independent existents. After highlighting (...) the central problems of paradigmatic trope theories, we discuss two more recent developments of trope bundle theory that also take non-relational tropes as independent existents, Anna-Sofia Maurin's and Douglas Ehring's independence theories. Finally, we present two alternative trope bundle theories, according to which tropes are dependent existents, dependence theories, namely, Arda Denkel's Saturation theory and our Strong Nuclear Theory (SNT). Although the latter two theories introduce existential dependencies among tropes, we argue that dependence theories provide a more satisfactory account of substances dividing into natural kinds than independence theories.

Trope theory is a leading metaphysical theory in analytic ontology. One of its classic statements is found in the work of Donald C. Williams who argued that tropes qua abstract particulars are the very alphabet of being. The concept of an abstract particular has been repeatedly attacked in the literature. Opponents and proponents of trope theory alike have levelled their criticisms at the abstractness of tropes and the associated act of abstraction. In this paper I defend the concept of a (...) trope qua abstract particular by rejecting arguments that purport to show that tropes should not be understood as abstract and by arguing that the abstractness of tropes plays an indispensable role in one of our more promising trope-theoretic analyses of universals and of concrete objects.

The concept of instantiation is realized differently across a variety of metaphysical theories. A certain realization of the concept in a given theory depends on what roles are specified and associated with the concept and its corresponding term as well as what entities are suited to fill those roles. In this paper, the classic realization of the concept of instantiation in a one-category ontology of abstract particulars or tropes is articulated in a novel way and defended against unaddressed objections.

I defend a reading of David Hume’s nominalism that he comes close to Keith Campbell's contemporary trope theory in the specific case of spatial properties. I argue that Hume's view should be construed as classifying spatial properties as Campbellian tropes (particular properties): abstract, particular, determinate and qualitatively simple properties. This has implications for reconstructing Hume's answer to the problem of universals. I argue that Hume’s account of objects resembling each other in respect of spatial properties is grounded in the resemblance (...) of tropes rather than in the resemblance of objects. (shrink)

The purpose of this work is to provide a metaphysical theory of properties and scientific laws. This sentence will require some unpacking. By a ‘metaphysical’ theory here, I mean a theory of what exists in the world. In this investigation I am primarily concerned with a theory of what properties there are in the world and the role they play in scientific laws. This may be contrasted with a linguistic or epistemic project, as it is not primarily about our language, (...) ideas, or theorizing but rather about what is in the world itself. Properties are what we may pre-philosophically think of as the characteristics of an object: such as its height, weight, color, etc. Investigation may cause us to doubt whether some of these pre-philosophical properties are genuine in a metaphysical sense: whether or not the property is actually present as a feature of the world. By scientific laws, I mean the statements we make in the form of exceptionless generalities about the world within the sciences. Here I do not mean to evaluate how science comes about these generalizations, only that they do and how these generalizations may be grounded in a metaphysical theory of properties. The link between these two things: properties and scientific laws, comes about because our scientific laws prominently feature properties: velocity, temperature, charge, viscosity, etc. After a review of some of the theories currently proposed in the philosophical literature along with a treatment of some of the problems that arise out of these theories, I will propose a new theory. This theory, entitled ‘Constitutive Trope Theory’ is a form of a ‘bundle trope theory’ as it proposes that objects in the world are composed entirely out of particularized properties. However, rather than proposing a primitive relation that does the bundling, this theory will propose that, at least for the objects we are familiar with, properties arise out of relations between lower-level properties that instantiate them. For example, a mammal may exist because of the relationship between the organs that lead to its unique properties as a mammal. Those organs in turn exist because of relationships between their cells that lead to their unique properties as a particular kind of organ. And so on down the chain until we hit ‘foundational properties’: properties which are not dependent on any other properties for their existence. I will say very little about these properties as I do not believe that any such properties have currently been found and will argue that such theorizing is premature before such properties have been empirically identified. Following this account, I will consider some of the problems that must be overcome and some final considerations in favor of this theory over other competing theories of properties and scientific laws.

Paper responding to critique of Maurin (2002) presented by Herbert Hochberg in his “Relations, Properties and Particulars” (2004).

Primary to both ontology and epistemology is the attributional union that properties and relations have with their subjects. Yet, the tradition’s understanding of attribution has been assessed as shallow, and its contemporary analysis deemed locked in a non-progressing stalemate. Central here is the historically dominant __in___herence_/_constituent_ construal of attribution, what, I argue, has remained obscure and unattended as to its background assumptions and their implications. On the analysis offered herein, I make precise and detail errors of the defining assumptions of (...) inherence theory and the _two-tiered nature_ it requires of attribution. Brought into relief will be the four elements involved in every attributional union, and what are the errors in a sequence of collapsing identities among them that define inherence theory. Along the way, clarification and warrant is provided for the alternative theses and their implications defining an __ad___herence_ theory of attribution, key features synopsized in the last section.

Kim has defended a solution to the exclusion problem which deploys the «causal inheritance principle» and the identification of instantiations of mental properties with instantiations of their realizing physical properties. I wish to argue that Kim's putative solution to the exclusion problem rests on an equivocation between instantiations of properties as bearers of properties and instantiations as property instances. On the former understanding, the causal inheritance principle is too weak to confer causal efficacy upon mental properties. And on the latter (...) understanding, the identification of mental and physical instantiations is simply untenable. (shrink)
