Objects and Properties

Ontic structural realism refers to the novel, exciting, and widely discussed basic idea that the structure of physical reality is genuinely relational. In its radical form, the doctrine claims that there are, in fact, no objects but only structure, i.e., relations. More moderate approaches state that objects have only relational but no intrinsic properties. In its most moderate and most tenable form, ontic structural realism assumes that at the most fundamental level of physical reality there are only relational properties. This (...) means that the most fundamental objects only possess relational but no non-reducible intrinsic properties. The present paper will argue that our currently best physics refutes even this most moderate form of ontic structural realism. More precisely, I will claim that 1) according to quantum field theory, the most fundamental objects of matter are quantum fields and not particles, and show that 2) according to the Standard Model, quantum fields have intrinsic non-relational properties.

The concepts of particular and universal have grown so familiar that their significance has become difficult to discern, like coins that have been passed back and forth too many times, worn smooth so their values can no longer be read. On the Genealogy of Universals seeks to overcome our sense of over-familiarity with these concepts by providing a case study of their evolution during the late nineteenth century and early twentieth century, a study that shows how the history of these (...) concepts is bound up with the origins and development of analytic philosophy itself. Understanding how these concepts were taken up, transfigured, and given up by the early analytic philosophers, enables us to recover and reanimate the debate amongst them that otherwise remains Delphic. This book begins from the early, originating texts of analytic philosophy that have hitherto baffled commentators, including Moore's early papers, and engages afresh with the neglected contributions of philosophical figures that historians of analytic philosophy have mostly since forgotten, including Stout and Whitehead. This sheds new light upon the relationships of Moore to Russell, Russell to Wittgenstein, and Wittgenstein to Ramsey. (shrink)

Bare particulars have received a fair amount of bad press. Many find such entities to be obviously incoherent and dismiss them without much consideration. Proponents of bare particulars, on their part, have not done enough to clearly motivate and characterize bare particulars, thus leaving them open to misinterpretations. With this paper, I try to remedy this situation. I put forward a much-needed positive case for bare particulars through the four problems that they can be seen to solve—The Problem of Individuation, (...) The Problem of Change, The Problem of Having a Property, and The Problem of Subtraction. I then distinguish and characterize three possible types of bare particulars—genuinely bare, constitutively bare, and thinly clothed—and consider how each of these cope with some classical and recent objections to bare particulars. I argue that the most troubling objections do not come from familiar quarters, but from examining how well such entities address all four of the ontological problems outlined. I ultimately conclude that the best contenders among the three types of bare particulars are the constitutively bare variety, but argue that, if they are to earn their keep, they must either share or turn over their individuating role to the ordinary particulars that they constitute.

As it is appropriate to regard mental events as properties of their subject rather than as entities, so it is appropriate to treat actions as properties of the agent rather than as particulars. It is argued that the property approach to action should not be rejected because of the implausibility of the theories of Goldman and Kim; for properties need not and should not be individuated in their way. It is also argued that the question of treating actions as particulars (...) or properties is to be settled on pragnatic grounds: it has no clear metaphysical significance. Finally it is argued that the logical form of action sentences, which Davidson endeavours to display by treating acts as particulars, can be shown with greater simplicity and plausibility on a property approach.

Formal ontology as it is presented in Husserl`s Third Logical Investigation can be interpreted as a fundamental tool to describe objects in a formal sense. It is presented one of the main sources: chapter five of Carl Stumpf`s Ûber den psycholoogischen Ursprung der Raumovorstellung (1873), and then it is described how Husserlian Formal Ontology is applied in Fifth Logical Investigation. Finally, it is applied to dramatic structures, in the spirit of Roman Ingarden.

What is the Bare Particular Theory? Is it committed, like the Bundle Theory, to a constituent ontology: according to which a substance’s qualities—and according to the Bare Particular Theory, its substratum also—are proper parts of the substance? I argue that Bare Particularists need not, should not, and—if a recent objection to ‘the Bare Particular Theory’ succeeds—cannot endorse a constituent ontology. There is nothing, I show, in the motivations for Bare Particularism or the principles that distinguish Bare Particularism from rival views (...) that entails a constituent ontology. I outline a version of Bare Particularism that in rejecting a constituent ontology avoids the New Objection. I argue against Theodore Sider that this really is a distinct theory to the version of Bare Particularism that endorses a constituent ontology, and not a mere terminological variant. I show that this, the best version of the Bare Particular Theory, is also defensible against the old objections. (shrink)

I offer a mereological bundle of universals theory of material objects. The theory says that objects are identical to fusions of immanent universals at regions of space. Immanent universals are in the objects that instantiate them, and they can be wholly located at many regions of space. The version of the bundle theory I offer explains these characteristics of immanent universals, and it captures the instantiation relation in terms of the part-whole relation. The version of the theory I offer is (...) simpler and more unified than other mereological bundle theories. Yet, it is not as encompassing as other versions. For I suppose throughout that space is a particular substance, but not a bundle of properties. (shrink)

Let $X$ be a smooth projective curve defined over an algebraically closed field $k$, and let $F_X$ denote the absolute Frobenius morphism of $X$ when the characteristic of $k$ is positive. A vector bundle over $X$ is called virtually globally generated if its pull back, by some finite morphism to $X$ from some smooth projective curve, is generated by its global sections. We prove the following. If the characteristic of $k$ is positive, a vector bundle $E$ over $X$ is virtually (...) globally generated if and only if $^* E\, \cong \, E_a\oplus E_f$ for some $m$, where $E_a$ is some ample vector bundle and $E_f$ is some finite vector bundle over $X$. If the characteristic of $k$ is zero, a vector bundle $E$ over $X$ is virtually globally generated if and only if $E$ is a direct sum of an ample vector bundle and a finite vector bundle over $X$.

This dissertation is an essay in analytic ontology whose main concern is to examine the ontological status of qualities and quality-instances. The primary thesis defended is that a Realist view of qualities is true--qualities are universals and not particulars--and quality-instances like red are complex entities with at least three constituents in them--a universal, an individuator, and a tie of predication. ;In the Introduction, six features of exemplification are clarified by examining different ways of assaying states of affairs like the-F-of-a . (...) The role of language in ontology is also discussed. It is argued that ontological problems cannot be reduced to linguistic phenomena, but the latter can provide limited, evidential support to a position taken on some ontological problem, such as the problems of universals. ;In chapters one through four, a view called Trope Nominalism is stated and criticized. In chapter one, Trope Nominalism is defined and the two main arguments for Trope Nominalism are refuted. Trope Nominalism is the view that quality-instances, such as red, are basic, simple, abstract particulars called tropes. "Universals," such as redness, are sets of red tropes that exactly resemble one another. Advocates are D. C. Williams and Keith Campbell. In chapter two, the Trope view of predication is criticized by focusing on the simplicity and individuation of tropes. In chapter three, the Trope view of abstract reference is criticized. In chapter four, the Trope view of exact similarity is rejected by showing it leads to a vicious infinite regress. ;In chapters five and six, different Realist accounts of qualities and quality-instances are treated. Chapter five shows that the Realist views of Nicholas Wolterstorff and Michael Loux are inadequate. Wolterstorff and Loux redefine Realism by holding that universals are kinds whose instances are simple entities that are members of their kinds. Chapter six presents what a Realist assay of qualities and quality-instances should look like and argues that, in one interpretation, Edmund Husserl held this view. Qualities are ones-in-many. Quality instances are complex entities. (shrink)

The past thirty years has witnessed a resurgence of interest in 'realist ontologies': views that treat properties and relations realistically. Such views necessitate a metaphysical account of the structure of concrete particulars. One such account is the Substratum theory of concrete particulars, on which concrete particulars are composed of their properties together with a substratum that individuates them and bears these properties. A traditional objection to this account is that the substratum would be unknowable. Recently, several philosophers supporting a realist (...) ontology have argued for versions of this traditional Substratum theory, insisting that this epistemic objection to the substratum can be overcome. I argue that this cannot be done. Specifically, I claim that either the substratum leads to a vicious regress or else it fails to meet epistemic constraints widely enforced in metaphysics. Therefore, realist ontologies must provide a Bundle theory of concrete particulars . ;Consequently, the traditional version of the Bundle theory, which construes properties to be universals, is assessed. The main objections that have been raised against this version of the theory are rejected; this includes what has been traditionally the most prominent objection, the charge that it is committed to the necessitation of the Identity of Indiscernibles. However, I also show that the theory requires applying the notion of bi-location to concrete particulars. I claim that this violates strong pre-theoretic intuitions about concrete particulars and renders the traditional Bundle theory inconsistent with a view attractive to contemporary realists, spacetime substantivalism. For these reasons, it is argued that the realist should adopt a Bundle theory that treats properties as tropes, rather than as universals. A Bundle theory formulated using tropes does not face the above limitations because it does not require the bi-location of concrete particulars. I also argue that the Bundle of tropes view has a further advantage over competing accounts of concrete particulars: it defuses the most serious theoretical obstacle to spacetime substantivalism: the notorious 'hole argument'.

The thesis is concerned with the outline of an ontology which admits only particulars and with the persistence of particulars through time. In Chapter 1 it is argued that a neglected class of particulars--the cases--have to be employed in order to solve the problem of universals, i.e., to give a satisfactory account of properties and kinds. In Chapter 2, two ways in which particulars could persist though time are distinguished. Difficulties are raised for the view that everything perdures through time, (...) i.e., the view that each persisting thing is a sum of continuous and dependent temporal parts. Objections to the view that people perdure are presented in Chapter 3, objections to the effect that such a view cannot capture salient truths about the nature of experience and wrongly implies that our special concern for ourselves, our friends and our familiars is irrational. An alternative account of persisting particulars is provided in Chapter 4 by way of given a theory of substances. Finally, in Chapter 5, this alternative account is applied to the issue of personal identity and to the issue of the identity over time of living things in general. A Hylomorphic View of living things is sketched and briefly defended. ;Throughout, certain themes recur: essentialism is taken to be relatively unproblematic, various connections between time and modality are exploited, reductionism is regarded as bearing the onus of proof, characterless entities such as prime matter, substrata, bare particulars and haecceities are rejected and the differences between the animate and the inanimate are emphasized.

The following paper explores a notion of particulars that permeates recent and less recent literature in philosophy of language and philosophy of mind. This notion of particulars relates to a distinction between conceptual and non-conceptual thought content. In the literature, this relation is discussed in terms of a distinction between thought of particulars and general thought . I focus on this distinction as it relates to two different interpretations of Fregean sense: one that treats sense as descriptive and the other (...) that recognizes that sense is not descriptive. I argue that the descriptive interpretation of Frege leads one to postulate non-conceptual content, a position which I further argue is untenable. I ultimately propose and argue that the non-descriptive interpretation of sense avoids a dilemma between a near-idealist view that leaves no room for particulars, and a realist view that leaves us with an odd notion of non-conceptual mental content.

In a recent article [Mertz 2001] in this journal I argued for the virtues of a realist ontology of relation instances (unit attributes). A major strength of this ontology is an assay of ontic ('material') predication that yields an account of individuation without the necessity of positing and defending 'bare particulars'. The crucial insight is that it is the unifying agency or combinatorial aspect of a relation instance as predicable that is for ontology the principium individuationis [Mertz 2002; 1996]. Or (...) in short, what is ontically predicable, precisely as such, is the cause of individuation. As a preface to this positive doctrine I offered arguments against the coherence of bare particulars as defended in an article by J. P. Moreland [1998]. In a reply contained in this issue Moreland and Timothy Pickavance (hereafter M/P) propose to answer my objections [2002]. The response that follows provides reasons why, I contend, M/P have not succeeded in parrying my objections to bare particulars. (shrink)

Not long ago, one of us has clarified and defended a bare particular theory of individuation. More recently, D. W. Mertz has raised a set of objections against this account and other accounts of bare particulars and proffered an alternative theory of individuation. He claims to have shown that 'the concept of bare particulars, and consequently substratum ontology that requires it, is untenable.' We disagree with this claim and believe there are adequate responses to the three arguments Mertz raises against (...) bare particulars. To substantiate this assertion, we clarify the nature of bare particulars as individuators, state Mertz's objections, and respond to them. We conclude that Mertz has failed to show that bare particular theory is untenable. (shrink)

In this paper I discuss Tim Maudlin’s attempt to reject the theory of universals based on the interpretation of gauge theories in the fiber bundle framework. The project is novel and assuring, but, I argue, it is vulnerable to several objections stemming from both metaphysics and physics. I complement his project by emphasizing two missing elements: first, a commitment to realism; second, the fundamentality or non-fundamentality of gauge theories.

In this article I examine an as yet unexplored aspect of J.P. Moreland’s defense of so-called bare particularism — the ontological theory according to which ordinary concrete particulars (e.g., Socrates) contain bare particulars as individuating constituents and property ‘hubs.’ I begin with the observation that if there is a constituency relation obtaining between Socrates and his bare particular, it must be an internal relation, in which case the natures of the relata will necessitate the relation. I then distinguish various ways (...) in which a bare particular might be thought to have a nature and show that on none of these is it possible for a bare particular to be a constituent of a complex particular. Thus, Moreland’s attempt to resurrect bare particulars as ontologically indispensable entities is not wholly without difficulties. (shrink)

A bare individual was conceived by Tichý as an individual such as if the property the individual instantiates is non-trivial , it is possible for the individual to lack it ; and for any trivial property that it cannot lack this kind of property. The exact readings of Tichý’s original formulations of bare individuals are subjected to a detailed analysis to reveal that any of them is refutable by means of Cmorejian objection that there exist contingent properties which are partly (...) essential . To avoid such objection, the present paper attempts to rebuild Tichý’s definitions into viable ones. (shrink)
