E. J. Lowe, a prominent figure in contemporary metaphysics, sets out and defends his theory of what there is. His four-category ontology is a metaphysical system which recognizes four fundamental categories of beings: substantial and non-substantial particulars and substantial and non-substantial universals. Lowe argues that this system has an explanatory power which is unrivalled by more parsimonious theories and that this counts decisively in its favour. He shows that it provides a powerful explanatory framework for a unified account of causation, (...) dispositions, natural laws, natural necessity and many other related matters, thus constituting a full metaphysical foundation for natural science.

This volume is a collection of papers that advance our understanding of the metaphysics of powers — properties such as fragility and electric charge. The metaphysics of powers is a fast developing research field with fundamental questions at the forefront of current research, such as Can there be a world of only powers? What is the manifestation of a power? Are powers and their manifestations related by necessity? What are the prospects for dispositional accounts of causation? The papers focus on (...) questions concerning the metaphysics of powers that cut across any particular subject-specific ontological domain -- whether philosophy of science, philosophy of mind, ethics, epistemology – investigating the metaphysical structure of powers, the nature of the manifestation of powers, the necessity or contingency of a power’s relation to its manifestations, and powers and causation. A number of authors also engage in discussion with Humean and neo-Humean treatments of causation, thereby making contributions to a larger metaphysical debate beyond powers. Additionally, the authors engage critically with the latest contributions to the debate on powers in the literature, thereby bringing together in a wholesome and analytical way the most recent and noteworthy theoretical developments in this research field.

The book covers a broad range of key topics, including theories of properties and particulars, the notion of truth-makers, powers and possibilities, material composition, and a variety of issues related to time and causation.

There is a largely unrecognized ambiguity concerning the nature of a trope. Disambiguation throws into relief two fundamentally different conceptions of a trope and provides two ways to understand and develop each metaphysical theory that put tropes to use. In this paper I consider the relative merits that result from differences concerning a trope’s ability to ground the character of ordinary objects. I argue that on each conception of a trope, there are unique implications and challenges concerning character-grounding.

In this paper I explore Michael Loux’s important distinction between “tropes” and “tropers”. First, I argue that the distinction throws into relief an ambiguity and discrepancy in the literature, revealing two fundamentally different versions of trope theory. Second, I argue that the distinction brings into focus unique challenges facing each of the resulting trope theories, thus calling into question an alleged advantage of trope theory—that by uniquely occupying the middle ground between its rivals, trope theory is able to recover and (...) preserve the insights of these views. Ultimately, the distinction suggests that trope theory is a divided house. (shrink)

Trope theory is an increasingly prominent contender in contemporary debates about the existence and nature of properties. But it suffers from ambiguity concerning the nature of a trope. Disambiguation reveals two fundamentally different concepts of a trope: modifier tropes and module tropes. These types of tropes are unequally suited for metaphysical work. Modifier tropes have advantages concerning powers, relations, and fundamental determinables, whereas module tropes have advantages concerning perception, causation, character-grounding, and the ontology of substance. Thus, the choice between modifier (...) tropes and module tropes is significant and divides the advantages of trope theory simpliciter. In addition, each resulting trope theory is unstable: modifier trope theory threatens to collapse into realism and module trope theory threatens to collapse into austere nominalism. This invites reflection on the stability of trope theory in general. (shrink)

Bare particulars tend to get a bad rap. But often, the arguments lodged against bare particulars seem to miss important aspects of the theoretical context of bare particulars. In particular, these arguments fail to situate bare particulars within a constituent ontology with substrates, and thus fail to appreciate an important consequence of that context: the need for two types of exemplification. In this paper, I do three things. First, I motivate and describe the need, given bare particulars, for two types (...) of exemplification, and explore more generally how constituent ontologies with substrates ought to think about exemplification. Second, I show how Andrew Bailey’s (2012) new argument against bare particulars fails when that need is charitably considered. Third, I highlight where bare particular theory ought to be pressed, which turns out to be precisely its account of exemplification. (shrink)

The paper argues that grounding is neither irreflexive, nor asymmetric, nor transitive. In arguing for that conclusion the paper also arguesthat truthmaking is neither irreflexive, nor asymmetric, nor transitive.

What does reality encompass? Is it exclusively physical, or does it include mental and 'abstract' aspects? What are the elements of being, reality's raw materials? John Heil offers stimulating answers to these questions framed in terms of a comprehensive metaphysics of substances and properties inspired by Descartes, Locke, and their successors.

My general aim in this paper is to shed light on the controversial concept of a bare particular. I do so by arguing that bare particulars are best understood in terms of the individuative work they do within the framework of a realist constituent ontology. I argue that outside such a framework, it is not clear that the notion of a bare particular is either motivated or coherent. This is suggested by reflection on standard objections to bare particulars. However, within (...) the framework of a realist constituent ontology, bare particulars provide for a coherent theory of individuation—one with a potentially significant theoretical price tag, but one that also has advantages over rival theories.

Properties and objects are everywhere, but remain a philosophical mystery. Douglas Ehring argues that the idea of tropes--properties and relations understood as particulars--provides the best foundation for a metaphysical account of properties and objects. He develops and defends a new theory of trope nominalism.

Ehring shows the inadequacy of received theories of causation, and, introducing conceptual devices of his own, provides a wholly new account of causation as the persistence over time of individual properties, or "tropes.".

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.

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)

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)

There are predicates and subjects. It is thus tempting to think that there are properties on the one hand, and things that have them on the other. I have no quarrel with this thought; it is a fine place to begin a theory of properties and property-having. But in this paper, I argue that one such theory—bare particularism—is false. I pose a dilemma. Either bare particulars instantiate the properties of their host substances or they do not. If they do not, (...) then bare particularism is both unmotivated and false. If they do, then the view faces a problematic—and, I shall argue, false—crowding consequence. (shrink)

Contemporary philosophers commonly suppose that any fundamental entities there may be are maximally determinate. More generally, they commonly suppose that, whether or not there are fundamental entities, any determinable entities there may be are grounded in, hence less fundamental than, more determinate entities. So, for example, Armstrong takes the physical objects constituting the presumed fundamental base to be “determinate in all respects” (1961, 59), and Lewis takes the properties characterizing things “completely and without redundancy” to be “highly specific” (1986, 60). (...) Here I look at the usually cited reasons for these suppositions as directed against the case of determinable properties, in particular, and argue that none is compelling (Sections 1 to 3). The discussion in Section 3 moreover identifies positive reason for taking some determinable properties to be part of a fundamental (or relatively fundamental) base. I close (Section 4) by noting certain questions arising from the possibility of fundamental determinables, as directions for future research. (shrink)

A tropel is a particular property: the redness of a rose, the roundness of the moon. It is generally supposed that tropes are individuated by primitive quantity: this redness, that roundness. I argme that the trope theorist is far better served by individuating tropes by spatiotemporal relation: here redness, there roundness. In short, tropes are not this-suches but here-suches.

Once we assume that objects are bundles of tropes, we want to know how the latter cohere. Are they held together by a substratum, are they linked by external relations or do they cling to one another by internal relations? This paper begins by exploring the reasons for eliminating the first two suggestions. Defending that the third option can be made plausible, it advances the following thesis: Maintaining that tropes are held in a compresence by appropriately qualified internal relations avoids (...) the consequence that such properties will be essential to the object. The specific targets of the second part of the paper include, first, a more precise description of the notion of a cohesive internal relation, and second, an explanation of how alteration is possible in an object the particular properties of which hold together by qualified internal relations.
