The paper deals with the notions of grounding and of existential dependence. It is shown that cases of existential dependence seem to be systematically correlated to cases of grounding and hence the question is raised what sort of tie might hold the two notions together so as to account for the observed correlation. The paper focusses on three possible ties between grounding and existential dependence: identity, definition, and grounding. A case for the definitional tie is made.

A fundamental entity is an entity that is ‘ontologically independent’; it does not depend on anything else for its existence or essence. It seems to follow that a fundamental entity is ‘modally free’ in some sense. This assumption, that fundamentality entails modal freedom (or ‘FEMF’ as I shall label the thesis), is used in the service of other arguments in metaphysics. But as I will argue, the road from fundamentality to modal freedom is not so straightforward. The defender of FEMF (...) should provide positive reasons for believing it, especially in light of recent views that are incompatible with it. I examine both direct and indirect routes to FEMF.

In this paper, I offer a new theory of grounding. The theory has it that grounding is a job description that is realized by different properties in different contexts. Those properties play the grounding role contingently, and grounding is the property that plays the grounding role essentially. On this theory, grounding is monistic, but ‘grounding’ refers to different relations in different contexts. First, I argue against Kit Fine’s monist univocalism. Next, I argue against Jessica Wilson’s pluralist multivocalism. Finally, I introduce (...) monist multivocalism, explicate three versions of it (of which the above is one), and show its advantages. (shrink)

The goal of this paper is to make headway on a metaphysics of social construction. In recent work, I’ve argued that social construction should be understood in terms of metaphysical grounding. However, I agree with grounding skeptics like Wilson that bare claims about what grounds what are insufficient for capturing, with fine enough grain, metaphysical dependence structures. To that end, I develop a view on which the social construction of human social kinds is a kind of realization relation. Social kinds, (...) I argue, are multiply realizable kinds. I depart from the Wilson by further arguing that an appeal to grounding is not otiose when it comes to social construction. Social construction, I claim, belongs to the “big-G” Grounding genus, but it is the specific “small-g” relation of realization at work in cases of human kind social construction. (shrink)

Identity and distinctness facts are ones like “The Eiffel Tower is identical to the Eiffel Tower,” and “The Eiffel Tower is distinct from the Louvre.” This paper concerns one question in the metaphysics of identity: Are identity and distinctness facts metaphysically fundamental or are they nonfundamental? I provide an overview of answers to this question.

Presentists, who believe that only present objects exist, should accept a thisness ontology, since it can do considerable work in defence of presentism. In this paper, I propose a version of presentism that involves thisnesses of past and present entities and I argue this view solves important problems facing standard versions of presentism.

This chapter aims to explore the intersection of Christian theism, a neo-Aristotelian gloss on metaphysical grounding, and creaturely participation in God. In section one, I aim to de- velop several core tenets at the heart of a theistic participatory ontology as it is found in the Christian tradition, what I call minimal participatory ontology. In section two, I examine the contemporary notion of metaphysical grounding, namely the formal and structure features of the grounding relation, and offer a grounding-theoretic framework for (...) understanding a mini- mal participatory ontology. Finally, in section three, I put forward a neo-Aristotelian account of metaphysical grounding in particular, one that is uniquely suited to capture the central tenets of minimal participatory ontology.

Ontological dependence is a relation—or, more accurately, a family of relations—between entities or beings. For there are various ways in which one being may be said to depend upon one or more other beings, in a sense of “depend” that is distinctly metaphysical in character and that may be contrasted, thus, with various causal senses of this word. More specifically, a being may be said to depend, in such a sense, upon one or more other beings for its existence or (...) for its identity. Some varieties of ontological dependence may be analyzed in modal terms—that is, in terms of distinctly metaphysical notions of possibility and necessity—while others seem to demand an analysis in terms of the notion of essence. The latter varieties of ontological dependence may accordingly be called species of essential dependence. Notions of ontological dependence are frequently called upon by metaphysicians in their proposed analyses of other metaphysically important notions, such as the notion of substance. (shrink)

After many years of enduring the drought and famine of Quinean ontology and Carnapian meta-ontology, the notion of ground, with its distinctively philosophical flavor, finally promises to give metaphysicians something they can believe in again and around which they can rally: their very own metaphysical explanatory connection which apparently cannot be reduced to, or analyzed in terms of, other familiar idioms such as identity, modality, parthood, supervenience, realization, causation or counterfactual dependence. Often, phenomena such as the following are cited as (...) putative examples of grounding connections: systematic connections between entire realms of facts (mental/physical; moral/natural; etc.); truthmaking (e.g., the relation between the truth of the proposition that snow is white and snow’s being white); logical cases (e.g., the connection between conjunctive facts or disjunctive facts and their constituent facts); the determinate/determinable relation (e.g., the relation between something’s being maroon and its being red). I argue in this paper that classifying all of these phenomena as exhibiting grounding connections does not achieve much in the way of illumination. In fact, by treating a collection of phenomena which is in fact heterogeneous as though it were homogeneous, we have, if anything, taken a dialectical step backward. (shrink)

Metaphysical orthodoxy holds that a privileged minority of properties carve reality at its joints. These are the so-called fundamental properties. This thesis concerns the contemporary philosophical debate about the nature of fundamental properties. In particular, it aims to answer two questions: What is the most adequate conception of fundamental properties? What is the “big picture” world-view that emerges by adopting such a conception? I argue that a satisfactory answer to both questions requires us to embrace a novel conception of powerful (...) qualities, according to which properties are at once dispositional and qualitative. By adopting the proposed conception of powerful qualities, an original theory of fundamental properties comes to light. I call it Dual-Aspect Account. In this thesis, I defend the Dual-Aspect Account and its superiority with respect to rival views of fundamental properties. I illustrate this claim by examining Dispositionalism, the view defended among others by Alexander Bird and Stephen Mumford, Categoricalism, which has been advocated notably by David Lewis and David Armstrong, and the Identity Theory of powerful qualities, primarily championed by C. B. Martin and John Heil. The latter is the standard conception of powerful qualities. However, in the literature, the Identity Theory faces the charge of contradiction. A preliminary task is therefore to show that a conception of powerful qualities is coherent. To accomplish this aim, I introduce the notion of an aspect of a property. On this interpretation, powerful qualities can be thought of as having dispositional and qualitative aspects. I show that such a conception allows us to disambiguate the claim that a property’s dispositionality is identical with its qualitativity, and evade the charge of contradiction. Aspects bring us other theoretical benefits. I illustrate this claim by showing how the Dual-Aspect Account offers us a promising theory of resemblance. I then compare its merits with David Armstrong’s theory of partial identity. The conclusion of this thesis is that the Dual-Aspect Account is better suited to capturing the world as we find it in everyday life and scientific investigation as compared to the theoretical positions examined. (shrink)

David Armstrong accepted the following three theses: universals are immanent, laws are relations between universals, and laws govern. Taken together, they form an attractive position, for they promise to explain regularities in nature—one of the most important desiderata for a theory of laws and properties—while remaining compatible with naturalism. However, I argue that the three theses are incompatible. The basic idea is that each thesis makes an explanatory claim, but the three claims can be shown to run in a problematic (...) circle. I then consider which thesis we ought to reject and suggest some general lessons for the metaphysics of laws. (shrink)

Supervenience is necessary co-variation between two sets of entities. In the good old days, supervenience was considered a useful philosophical tool with a wide range of applications in the philosophy of mind, metaethics, epistemology, and elsewhere. In recent years, however, supervenience has fallen out of favor, giving place to grounding, realization, and other, more metaphysically “meaty”, notions. The emerging consensus is that there are principled reasons for which explanatory theses cannot be captured in terms of supervenience, or as the slogan (...) goes: “Supervenience Is Nonexplanatory”. While SIN is widely endorsed, it is far from clear what it amounts to and why we should believe it. In this paper, I will distinguish various theses that could be meant by it, and will argue that none of them is both interesting and plausible: on some interpretations of ‘explanatory’, we have no reason to believe that supervenience is unexplanatory, while on other interpretations, supervenience is indeed unexplanatory, but widely accepted textbook cases of explanatory relations come out as unexplanatory, too. This result raises doubts as to whether there is any interesting sense in which SIN is true, and suggests that the contemporary consensus about supervenience is mistaken. (shrink)

Truths depend upon what there is. So say many. A significant subset of that group say more; they say that the best way—perhaps the only way—to make sense of the claim that truth depends upon what there is, is to adopt a form of truth-maker theory. Truth-maker theorists claim that truths require ground; what’s true must depend upon what there is. Typically, truth-maker theory isn’t seen as a theory about the nature of truth. Rather, it’s seen as a theory about (...) what truths must do. Truths must depend. Relatedly, the claim that truths require ‘truth-makers’, that is, some putative ontological grounds, is used as a methodological tool in metaphysics. Put somewhat crudely, fix on what truths there are and locate the truth-makers—if necessary, add to your ontology until you satisfy this demand for truth-makers. Truth-making is thus at once both narrow and broad. It’s narrow insofar as it’s not a theory (it’s not a claim) about the nature of truth, and yet it’s broad insofar as it enables us to determine our ontological commitments. We take this to be a two-part orthodoxy about truth-making. We reject the orthodoxy on both counts. (shrink)

In a series papers, Jonathan Schaffer defended priority monism, the thesis that the cosmos is the only fundamental material object, on which all other objects depend. A primitive notion of dependence plays a crucial role in Schaffer’s argu- ments for priority monism. The goal of this paper is to scrutinize this notion and also to shed new light on what is at stake in the debate. I present three familiar arguments for priority monism and point out that each relies on (...) a connecting principle that ties dependence to other metaphysical relations. I then argue for two desiderata: the relation between dependence and other metaphysical relations needs to be strong enough to establish that other metaphysical relations are relevant to the direction of dependence but not so strong as to leave no room for revisionary versions of priority monism. I propose a particular way of meeting these desiderata, according to which the target notion of dependence is graded rather than all-or-nothing. One upshot is that we should be less preoccupied with priority monism itself and should instead focus on specific aspects of a broader monistic worldview. (shrink)

Surface presentism is the combination of a general relativistic physics with a presentist metaphysics. In this paper, we provide an argument against this combination based on black holes. The problem focuses on the notion of an event horizon. We argue that the present locations of event horizons are ontologically dependent on future black hole regions, and that this dependence is incompatible with presentism. We consider five responses to the problem available to the surface presentist, and argue that none succeed. Surface (...) presentism thus faces the prospect of refutation based on evidence that confirms the existence of black holes. (shrink)

Desires matter. What are desires? Many believe that desire is a motivational state: desiring is being disposed to act. This conception aligns with the functionalist approach to desire and the standard account of desire's role in explaining action. According to a second influential approach, however, desire is first and foremost an evaluation: desiring is representing something as good. After all, we seem to desire things under the guise of the good. Which understanding of desire is more accurate? Is the guise (...) of the good even right to assume? Should we adopt an alternative picture that emphasizes desire's deontic nature? What do neuroscientific studies suggest? -/- Essays in the first section of the volume are devoted to these questions, and to the puzzle of desire's essence. In the second part of the volume, essays investigate some implications that the various conceptions of desire have on a number of fundamental issues. For example, why are inconsistent desires problematic? What is desire's role in practical deliberation? How do we know what we want? -/- This volume will contribute to the emergence of a fruitful debate on a neglected, albeit crucial, dimension of the mind. (shrink)

RESUMEN Trabajos recientes han propuesto un tratamiento de la fundación “a la imagen de la causalidad”. Hay importantes analogías entre la fundación y la causalidad: ambas parecen ser relaciones de ‘construcción’, ambas parecen ser órdenes estrictos y ambas parecen ser representables por modelos de ecuaciones estructurales. Pero también parece que hay importantes diferencias, porque la causalidad es usualmente considerada como una relación externa, mientras que la fundación es interna; hay casos de causalidad probabilística, pero no hay nada como una fundación (...) probabilística; la fundación se considera una relación ‘bien fundada’, pero no la causalidad; la fundación implica superveniencia ontológica, pero no la causalidad. Se argumenta aquí que la mayoría de estas supuestas diferencias están motivadas por una concepción humeana de la causalidad en la que no hay conexiones necesarias entre causa y efecto. Una perspectiva no humeana de la causalidad, sin embargo, hace que la unificación de la fundación y la causalidad sea mucho más razonable que cualquier tratamiento separado. ABSTRACT Recent works have proposed a treatment of grounding “in the image of causation”. There are important analogies between grounding and causation: both seem to be ‘building’ relations, both seem to be strict orders, and both seem amenable to representation by models of structural equations. But it seems also that there are important differences, because causation is usually considered as an external relation, while grounding is internal; there are cases of probabilistic causation, but there is nothing like probabilistic grounding; grounding is taken to be a well-founded relation, but not causation; grounding entails ontological supervenience, but not causation. It is argued here that most of those supposed differences are motivated by a Humean conception of causation in which there are no necessary connections between cause and effect. A non-Humean view of causation, though, makes the unification of grounding and causation much more reasonable that any separate treatment. (shrink)

This article outlines a realist theory of aesthetic properties as higher-order manifest properties and defends it from several objections, including a possible conflict with contextualist approaches to the aesthetic properties of works of art.

Descartes notoriously characterizes substance in two ways: first, as an ultimate subject of properties ; second, as an independent entity. The characterizations have appeared to many to diverge on the definition as well as the scope of the notion of substance. For it is often thought that the ultimate subject of properties need not—and, in some cases, cannot—be independent. Drawing on a suite of historical, textual, and philosophical considerations, this essay argues for an interpretation that reconciles Descartes's two characterizations. It (...) proposes that both characterizations invoke a type of independence that obtains just in case there is no relation to another entity that holds by the nature of the entity in question. Even though the ultimate subject of properties is sometimes not independent in other respects, it satisfies this independence-by-nature condition. (shrink)

A new set of metaphysical arguments in favour of fundamental reality is proposed in the article. For this purpose the notion of the state of the world is introduced. The standard concept of grounding underlying metaphysical foundationalism is taken into account. The correspondence of the new notion and the initial principles of metaphysical fundamentalism are confirmed. The proof of fundamental reality existence is represented based on formulated principles and empirical data.

I provide a new account of what it is for the laws of nature to govern the evolution of events. I locate the source of governance in the content of law propositions. As such, I do not appeal to primitive notions of ground, essence, or production to characterize governance. After introducing the account, I use it to outline previously unrecognized varieties of governance. I also specify that laws must govern to have two theoretical virtues: explanatory power as well as a (...) theoretical virtue I call expansiveness. A theory is expansive, roughly, when it can do more with less. (shrink)

The paper takes up Bell's “Everett theory” and develops it further. The resulting theory is about the system of all particles in the universe, each located in ordinary, 3-dimensional space. This many-particle system as a whole performs random jumps through 3N-dimensional configuration space – hence “Tychistic Bohmian Mechanics”. The distribution of its spontaneous localisations in configuration space is given by the Born Rule probability measure for the universal wavefunction. Contra Bell, the theory is argued to satisfy the minimal desiderata for (...) a Bohmian theory within the Primitive Ontology framework. TBM's formalism is that of ordinary Bohmian Mechanics, without the postulate of continuous particle trajectories and their deterministic dynamics. This “rump formalism” receives, however, a different interpretation. We defend TBM as an empirically adequate and coherent quantum theory. Objections voiced by Bell and Maudlin are rebutted. The “for all practical purposes”-classical, Everettian worlds exist sequentially in TBM. In a temporally coarse-grained sense, they quasi-persist. By contrast, the individual particles themselves cease to persist. (shrink)

This paper evaluates six contenders which might be invoked by essentialists in order to meet Quine’s challenge, viz., to provide necessary and sufficient conditions for the crossworld identity of individuals: (i) an object’s qualitative character; (ii) matter; (iii) origins; (iv) haecceities or primitive non-qualitative thisness properties; (v) “world-indexed properties”; and (iv) individual forms. The first three candidates, I argue, fail to provide conditions that are both necessary and sufficient for the crossworld identity of individuals; the fourth and fifth criteria are (...) open to the charge that they do not succeed in meeting Quine’s demand in an explanatorily adequate fashion. On balance, then, individual forms, or so I propose, deserve to be taken very seriously as a possible response to Quine’s challenge, especially by neo-Aristotelians who are already committed to a hylomorphic conception of composite concrete particular objects for other reasons. Theorists who also accept a non-modal conception of essence, i.e., a conception according to which essence is not reducible to modality, in addition face the further difficult task, over and above what is required to meet Quine’s challenge, of having to explain how an object’s de re modal profile in some way follows from facts about its essence. Haecceities and world-indexed properties, as I indicate, are unlikely to be of much help with respect to this second challenge, while the forms of hylomorphic compounds are in fact well-suited for this purpose.

This chapter reviews several varieties of grounding skepticism as well as responses that have been proposed by grounding enthusiasts to considerations raised by grounding skeptics. Grounding skeptics, as I conceive of them here, are theorists who belong to one of the following two schools of thought. “Old-school” grounding skeptics doubt the theoretical utility of the grounding idiom by denying one of its presuppositions, viz., that this notion is at least intelligible or coherent. “Second-generation” grounding skeptics call into question the theoretical (...) utility of the grounding idiom for other reasons; their skeptical doubts tend to focus on one of the following three purported theoretical virtues grounding enthusiasts ascribe to their idiom: (i) its alleged power to unify an apparently heterogeneous collection of phenomena; (ii) its alleged power to capture and/or elucidate the distinction between the fundamental and the non-fundamental; or (iii) the alleged metaphysical (as opposed to mind-dependent, epistemic, or psychological) utility of grounding claims. Grounding enthusiasts have already formulated responses to many of the objections described in this chapter. At this point, however, it is fair to say that the state of the literature is still evolving, and no conclusive judgment can therefore be reached as of yet as to whether grounding enthusiasts or grounding skeptics have gained the upper hand in these debates. In the meantime, though, grounding skeptics continue to maintain that the classification of factual and/or nonfactual connections under the rubric of grounding does not really help us illuminate the nature of the connections at issue; instead, from the view of the grounding skeptic, we are better off studying these various connections separately and in their own right.

In the paper I discuss the problem of the nature of the relationship between objects and their properties. There are three contexts of the problem: of comparison, of change and of interaction. Philosophical explanations of facts indicated in the three contexts need reference to properties and to a proper understanding of a relationship between them and their bearers. My aim is to get closer to this understanding with the use of some models but previously I present the substantialist theory of (...) object and shortly argue for its main theses. The two models enabling us the understanding of the subject–properties structure are: the plastic stuff model and the functional model. On the ground of the first a subject is compared to a piece of plastic stuff which is informed by different shapes. Properties are ways how a subject is, they “give” some “figure” to a subject. The core idea of the second model is that essences are immanent functional laws governing correlations of properties. As such they are similar to mathematical functions which are saturated by values. The relationship between a subject and properties can be grasped by analogy to such a saturation. (shrink)

Accounts of logical independence which coincide when applied in the case of classical logic diverge elsewhere, raising the question of what a satisfactory all-purpose account of logical independence might look like. ‘All-purpose’ here means: working satisfactorily as applied across different logics, taken as consequence relations. Principal candidate characterizations of independence relative to a consequence relation are that there the consequence relation concerned is determined by only by classes of valuations providing for all possible truth-value combinations for the formulas whose independence (...) is at issue, and that the consequence relation ‘says’ nothing special about how those formulas are related that it does not say about arbitrary formulas. Each of these proposals returns counterintuitive verdicts in certain cases—the truth-value inspired approach classifying certain cases one would like to describe as involving failures of independence as being cases of independence, and the de Jongh approach counting some intuitively independent pairs of formulas as not being independent after all. In final section, a modification of the latter approach is tentatively sketched to correct for these misclassifications. The attention is on conceptual clarification throughout, rather than the provision of technical results. Proofs, as well as further elaborations, are lodged in the ‘longer notes’ in a final Appendix.

The relation of ontological dependence or grounding, expressed by the terminology of separation and priority in substance, plays a central role in Aristotle’s Categories, Metaphysics, De Anima and elsewhere. The article discusses three current interpretations of this terminology. These are drawn along the lines of, respectively, modal-existential ontological dependence, essential ontological dependence, and grounding or metaphysical explanation. I provide an opinionated introduction to the topic, raising the main interpretative questions, laying out a few of the exegetical and philosophical options that (...) influence one’s reading, and locating questions of Aristotle scholarship within the discussion of ontological dependence and grounding in contemporary metaphysics.

Abstract artifacts such as musical works and fictional entities are human creations; they are intentional products of our actions and activities. One line of argument against abstract artifacts is that abstract objects are not the kind of objects that can be created. This is so, it is argued, because abstract objects are causally inert. Since creation requires being caused to exist, abstract objects cannot be created. One common way to refute this argument is to reject the causal inefficacy of abstracta. (...) I argue that creationists should rather reject the principle that creation requires causation. Creation, in my view, is a non-causal relation that can be explained using an appropriate notion of ontological dependence. The existence and the creation of abstract artifacts depend on certain individuals with appropriate intentions, along with events of a certain kind that include but are not limited to creations of certain concrete objects.

Evaluativism about desire, the view that desires just are, or necessarily involve, positive evaluations of their objects, currently enjoys widespread popularity in many philosophical circles. This chapter argues that evaluativism, in both of its doxastic and perceptual versions, overstates and mischaracterises the connection between desires and evaluations. Whereas doxastic evaluativism implausibly rules out cases where someone has a desire, despite evaluating its object negatively, being uncertain about its value, or having no doxastic attitude whatsoever towards its evaluative status at all, (...) perceptual evaluativism cannot even properly apply to the large class of standing desires. It is also argued that evaluativism about desire is not even well-motivated in the first place: the theory is supposed to solve a particular puzzle about the role desires play in the explanation of action, yet, in fact, it does not offer any help whatsoever in dealing with the relevant puzzle.

The notion of fundamentality is supposed to play an important role in philosophical inquiry and scientific theorising. Yet there is no consensus on how to formulate it in precise terms. According to a promising view, fundamentality is a form of ontological independence. This view has the merit of capturing a natural connection between fundamentality and ontological dependence. However, it has been recently argued that it is possible that there are fundamental and yet ontologically dependent entities; therefore, we should not characterise (...) the fundamental in terms of ontological independence. My aim is to show that such a possibility does not threaten a conception of fundamentality as a form of ontological independence. I illustrate this claim by providing a definition of equifundamentality and showing that fundamental and yet ontologically dependent entities can be treated as equifundamental. (shrink)

In his influential article ‘Essence and Modality’, Fine proposes a definition of necessity in terms of the primitive essentialist notion ‘true in virtue of the nature of’. Fine’s proposal is suggestive, but it admits of different interpretations, leaving it unsettled what the precise formulation of an Essentialist definition of necessity should be. In this paper, four different versions of the definition are discussed: a singular, a plural reading, and an existential variant of Fine’s original suggestion and an alternative version proposed (...) by Correia which is not based on Fine’s primitive essentialist notion. The first main point of the paper is that the singular reading is untenable. The second that given plausible background assumptions, the remaining three definitions are extensionally equivalent. The third is that, this equivalence notwithstanding, Essentialists should adopt Correia’s version of the definition, since both the existential variant, which has de facto been adopted as the standard version of the definition in the literature, and the plural reading suffer from problems connected to Fine’s primitive essentialist notion.

I argue that Metaphysicsλ‎ is a unified work, and one which is not a continuation of the central books ΖΗΘ‎. It outlines an extensive project in First Philosophy, which has close connections with ΑΒΓΕ‎, but which proceeds on a different trajectory from ΖΗ‎. The principal problem in understanding λ‎ as a whole is how to reconcile Aristotle's explicit presentation of the book as a highly unified study with the disparate character of its two halves – the first a general‐metaphysical enquiry (...) into the features which changeable substances have as being substances of that kind, the second a detailed investigation of the specific character and activity of immaterial substances. My paper aims to show how this reconciliation is possible, and what we can learn about Aristotle's conception of first philosophy as a result. (shrink)

Words are indispensable linguistic tools for beings like us. However, there is not much philosophical work done about what words really are. In this paper, I develop a new ontology for words. I argue that words are abstract artifacts that are created to fulfill various kinds of purposes, and words are abstract in the sense that they are not located in space but they have a beginning and may have an end in time given that certain conditions are met. What (...) follows from this two-fold argument is that words, from an ontological point of view, are more like musical works, fictional characters or computer programs, than numbers or sets.

In his “Farewell to Substance: A Differentiated Leave-Taking”, Peter Simons reaches the provocative conclusion that the concept of substance, as it is employed by metaphysicians, has become obsolete, since in the end there may be nothing at all which answers to it. No harm is done, Simons allows, if we continue to retain an everyday notion of substance, as long as we are aware of the limitations of this practice: there is no reason in general to expect that what is (...) salient from our specifically human point of view will retain a special place in light of our most considered scientific and metaphysical theories of the world. In this paper, I argue that, contrary to Simons’ pessimistic outlook, the concept of substance continues to retain its importance for metaphysics. Among the primary explanatory roles played by the concept of substance in metaphysics is its use in designating certain kinds of entities as occupying a privileged position relative to a particular ontology. But disputes over substancehood can also target the criteria themselves relative to which an ontologically privileged position is awarded to certain taxonomic categories. In these uses, we see the concept of substance employed in an absolute, a relational and a comparative sense, to designate items as substances simpliciter, as the substances of something else, or as more or less deserving of substance status.

Following W.V. Quine’s lead, many metaphysicians consider ontology to be concerned primarily with existential questions of the form, “What is there?”. Moreover, if the position advanced by Rudolf Carnap, in his seminal essay, “Empiricism, Semantics, and Ontology ”, is correct, then many of these existential ontological questions ought to be classified as either trivially answerable or as “pseudo-questions”. One may justifiably wonder, however, whether the Quinean and Carnapian perspective on ontology really does justice to many of the most central concerns (...) of this discipline. This chapter argues, by considering a particular ontological dispute between two different kinds of trope theorists, that some of the most interesting and important debates which properly belong to the study of being, whether we call it “metaphysics” or “ ontology ”, do not concern existential questions at all; rather, such disputes in some cases focus on non-existential disagreements over questions of fundamentality.

Kit Fine and Gideon Rosen propose to define constitutive essence in terms of ground-theoretic notions and some form of consequential essence. But we think that the Fine–Rosen proposal is a mistake. On the Fine–Rosen proposal, constitutive essence ends up including properties that, on the central notion of essence, are necessary but not essential. This is because consequential essence is closed under logical consequence, and the ability of logical consequence to add properties to an object’s consequential essence outstrips the ability of (...) ground-theoretic notions, as used in the Fine–Rosen proposal, to take those properties out. The necessary-but-not-essential properties that, on the Fine–Rosen proposal, end up in constitutive essence include the sorts of necessary-but-not-essential properties that, others have noted, end up in consequential essence.

I defend a novel view of how social kinds (e.g., money, women, permanent residents) depend on our mental states. In particular, I argue that social kinds depend on our mental states in the following sense: it is essential to them that they exist (partially) because certain mental states exist. This analysis is meant to capture the very general way in which all social kinds depend on our mental states. However, my view is that particular social kinds also depend on our (...) mental states in more specific ways—some of them causal, others metaphysical. I defend a minimal but metaphysically important notion of essence—one that takes as primary that the essential properties of a kind constitute its identity—and argue that this minimal notion of essence is all that is needed to vindicate my claim that social kinds are essentially mind-dependent.

In this paper I analyze the most controversial thesis of Aristotelian substantialism, namely, that substances cannot be composed of other substances. I call this position the Mereological Limitation Thesis. I find MLT valid and defend it. My argument for MLT is a version of the argument from the unicity of substantial form. Every substance can have only one substantial form, thus, if some substances compose the object O, then what binds them is only a set of their accidental forms and (...) in the result thereof O is not a substance. I argue against the relativization of the substantiality of forms to the level of composition by showing that substantial forms must be absolutely identity-independent. In the last section I specify the ontological status of parts of substances and argue that they are spatially distributed bundles of accidents of a compound substance itself. (shrink)

The hole argument purports to show that all spacetime theories of a certain form are indeterministic, including the General Theory of Relativity. The argument has given rise to an industry of searching for a metaphysics of spacetime that delivers the right modal implications to rescue determinism. In this paper, I first argue that certain prominent extant replies to the hole argument—namely, those that appeal to an essentialist doctrine about spacetime—fail to deliver the requisite modal implications. As part of my argument, (...) I show that threats to determinism of the sort brought out by the hole argument are more general than has heretofore been recognized. I then use these results to propose a novel essentialist doctrine about spacetime that successfully rescues determinism, what I call sufficiency metric essentialism. However, I go on to argue that once we realize what an essentialist doctrine about spacetime must look like in order to address the hole argument, we should reject all such doctrines, because they can't fulfill their ambition of improving on standard modal replies to the argument. I close by suggesting some lessons for future work on spacetime and the metaphysics of physics more broadly, and also drawing some general morals for contemporary metaphysics, in particular about (i) whether essence can be used to articulate a precise structuralist doctrine, and (ii) the relationship between essence and modality.

This dissertation investigates grounding, the relation of non-causal determination whereby one fact obtains in virtue of some other fact or facts. Although considerations of grounding have been central throughout Western philosophy, the last 15-20 years have seen a renaissance of systematic work on grounding in analytic philosophy. The aim of the dissertation is to contribute to our understanding of the nature of grounding and its relation to other central phenomena in metaphysics. -/- Chapter 1 of the dissertation provides a brief (...) presentation of grounding and introduces some distinctions of relevance to later chapters. Chapter 2 discusses the question of whether grounding can be reduced. Four reductive accounts – in terms of fundamentality and supervenience, essence, reduction, and metaphysical laws respectively – are considered. All of these accounts are found to be subject to objections and are consequently rejected. -/- Chapter 3 considers the relation between grounding and another important phenomenon in metaphysics, namely ontological dependence. The question of the relation between the two is approached through an investigation of their modal connection (or lack thereof). It is argued that on the common assumption that grounding is a factive relation, ontological dependence can be shown to be neither necessary nor sufficient for grounding. Furthermore, to get any form of modal connection between the two relations, one needs to move to a non-factive conception of grounding or consider generic ontological dependence and accept a potentially controversial principle about the modal behaviour of grounding. Even then, the modal connection between grounding and ontological dependence is weak and subject to qualifications. -/- Chapter 4 develops and defends the novel notion of metaphysically opaque grounding. It is commonly assumed that grounding is an especially intimate and powerful connection and enables a form of explanation that is particularly strict and illuminating. An arguably related idea is that grounding is necessarily connected with the core features of things – their essences or natures. Metaphysically opaque grounding constitutes a form of grounding that falsifies both of these ideas. Chapter 4 makes the notion of metaphysically opaque grounding precise, motivates the idea that there are genuine cases of such grounding, explores its consequences for the theory of grounding, and defends the notion from potential objections, concluding that there are currently no strong reasons to rule out opaque grounding.

What is it for something to be essential to an item? For some time, it was standard to think that the concept of necessity alone can provide an answer: for something to be essential to an item is for it to be strictly implied by the existence of that item. We now tend to think that this view fails because its analysans is insufficient for its analysandum. In response, some argue that we can supplement the analysis in terms of necessity (...) with a further condition. In this paper I argue that this view is untenable in its current form. I then provide a glimmer of hope to those who think that essence is at least partially analyzable in terms of necessity. (shrink)

Kit Fine’s arguments in Essence and Modality are widely accepted as being a decisive blow against modal essentialism. A selection of replies exist that have done little to counter the general view that modally construed essence is out of touch with what we really mean when we make essentialist claims. I argue that Fine’s arguments fail to strike a decisive blow, and I suggest a new interpretation of the debate that shows why Fine’s arguments fall short of achieving their goal.

One of the issues that deeply interested the philosophers of late antiquity, the Ancient Greek Commentators, concerns the priority of substances. While questions concerning ontological priority have recently attracted attention in Aristotelian scholarship and contemporary metaphysics, the Commentators’ discussions have not yet received the attention they deserve. My aim is to start to fill in this gap, by focusing on John Philoponus’s account of the priority of substances in his commentary on Aristotle’s "Categories". In particular, I aim to show how (...) Philoponus develops and defends the view that, while particular substances enjoy priority over accidents and concepts (“universals after the many”), they do not enjoy priority over all other things. Rather, a certain type of universal substance (“universals prior to the many”) enjoys priority over particulars. (shrink)
