This paper asks: Is the quantifier variantist committed to metaphysical vagueness? My investigation of this question goes via a study of vague existence. I’ll argue that the quantifier variantist is committed to vague existence and that the vague existence posited by the variantist requires a puzzling sort of metaphysical vagueness. Specifically, I distinguish between (what I call) positive and negative metaphysical vagueness. Positive metaphysical vagueness is (roughly) the claim that there is vagueness in the world; negative metaphysical vagueness is (roughly) (...) the claim that there is vagueness that is not in our language or thought. I’ll argue that the quantifier variantist’s commitment to vague existence comes with positive metaphysical vagueness -- even if it doesn't require negative metaphysical vagueness. (shrink)

We provide an overview of the meta-ontological position known as "Quantifier Variance".

Genera, typically hand-in-hand with their branching species, are essential elements of vocabulary-based information constructs, in particular scientific taxonomies. Should they also feature in formal ontologies, the highest of such constructs? I argue in this article that the answer is “Yes” and that the question posed in its title also has a Yes-answer: The way medieval ontologists sliced up the world into genera does matter to formal ontology. More specifically, the way Dietrich of Freiberg, a Latin scholastic, conceived and applied strictly (...) generic criteria to slice up the world into its entities can provide some guidelines to the field of formal ontology with respect to not only its contents, but also its scope. In particular, Dietrich's information criterion plays here a central role. (shrink)

It is fundamental that, in philosophy, we make sure that we are not mistaking merely verbal disputes, or “conceptual” disputes, for substantive ones. This essay presents a tripartite framework that is useful for clarifying cases where it is difficult to tell whether we are engaged in substantive or non-substantive disputes. For this purpose, the essay offers some combinatorial possibilities between the following levels: verbal, conceptual, and objectual. We need to distinguish whether we are arguing about the world, concepts, or words (...) to avoid talking at cross-purposes and to recognize when our disputes are not worth the time. Distinguishing between these three levels can also throw light and guide research on conceptual engineering, metalinguistic negotiations, metaontology, and so on. (shrink)

In this article, I defend Lewisian modal realism against objections arising from the possibility of ‘Island Universes’ and other similar cases. The problem comes from Lewis’ claim that possible worlds are spatio-temporally isolated. I suggest a modification of Lewisian modal realism in order to avoid this family of objections. This modification may sound quite radical since it amounts to abandoning the very notion of a possible world, but as radical as it may sound it in fact remains well in the (...) spirit of Lewis’ original view.

Numerical identity is the non-relational sameness of an object to itself. It is concerned with understanding how entities undergo change and maintain their identity. In substance metaphysics, an entity is considered a substance with an essence and such an essence is the source of its power. However, such a framework fails to explain the sense in which an entity is still the entity it was, amidst changes. Those who claim that essence is unaffected by existence are faced with challenge of (...) exploring the epistemic access to such an essence, which is questionable at best. Process metaphysics is a strong candidate for a theory that can ontologically explain regularity and change without appeal to essence. Process and its interactions is the main category. Every process is an emergent organization of constitutive interactions and is individuated on the basis of its interactive powers, that is, the ways in which it interacts with the world around it. Interactions are situated adaptation to changes. In this way, changes are crucial within process metaphysics and are included in the starting point of its investigation. What seems to the naked eyes as one-ness/singularity is a complex process where an organization of interactions is emerging from moment to moment by continually adapting to the changes around and within it. The question of numerical identity over time becomes valid only within substance metaphysics which has no space to accommodate change, due to its allegiance to essence. (shrink)

Deflationism is the view that certain metaphysical debates are defective, leaving it open whether the defect is best explained in semantic, conceptual, or epistemic terms. Local semantic deflationism is the thesis that familiar metaphysical debates, which appear to be about the existence and identity of material objects, are merely verbal. It’s a form of local deflationism because it restricts itself to one particular area of metaphysics. It’s a form of semantic deflationism because the defect it purports to identify in these (...) debates is explained in terms of the broadly semantic notion of a merely verbal disputation. Three questions about this thesis are asked and answered here. Does a commitment to the principle of interpretive charity support it? No. Does it avoid the problems that plagued Carnap? No. Does it support a linguistic turn with respect to questions about the nature of material things? No. The central take-home message is that local semantic deflationism is unstable: advocates of the view must admit that debates about material coincidence and identity are substantive. (shrink)

Several metaphysical debates have typically been modeled as oppositions between a relationist approach and a substantivalist approach. Such debates include the Bundle Theory and the Substratum Theory about ordinary material objects, the Bundle (Humean) Theory and the Substance (Cartesian) Theory of the Self, and Relationism and Substantivalism about time. In all three debates, the substantivalist side typically insists that in order to provide a good treatment of the subject-matter of the theory (time, Self, material objects), it is necessary to postulate (...) the existence of a certain kind of substance, while the other side, the relationist one, characteristically feels that this is an unnecessary expense and that one can get the job done in an ontologically cheaper way just with inter-related properties or events. In this paper I shall defend the view that there is much less of a disagreement between relational ontologies and substantival ontologies than it is usually thought. I believe that, when carefully examined, the two sides of the debate are not that different from each other, in all three cases of pairs of views mentioned above. As we will see, both the relational side and the substantival side work in the same way, suffer from and answer the same objections, and are structurally extremely similar. It will be an important question – one that I shall discuss in detail, and that is indeed the main point of interest for me in this paper – whether this means that the two sides of the debate are somehow 'equivalent' or not, and what 'equivalent' could mean.

When some objects are the parts of another object, they compose that object and that object is composite. This article is intended as an introduction to the central questions about composition and a highly selective overview of various answers to those questions. In §1, we review some formal features of parthood that are important for understanding the nature of composition. In §2, we consider some answers to the question: which pluralities of objects together compose something? As we will see, the (...) dominant answers are all of them and none of them. In §§3-4, we examine one of the main arguments that has driven philosophers to these extreme answers: the argument from vagueness. In §5, we turn to the question of whether composition is unique: is it sometimes the case that some things compose more than one thing? Finally, in §6, we turn from the question of which composites exist to the question of which composites exist fundamentally. (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.

The aim of this article is to develop an argument against metaphysical debates about the existence of human races. I argue that the ontology of race is underdetermined by both empirical and non-empirical evidence due to a plurality of equally permissible candidate meanings of "race." Furthermore, I argue that this underdetermination leads to a deflationist diagnosis according to #hich disputes about the existence of human races are non-substantive verbal disputes. $hile this diagnosis resembles general deflationist strategies in contemporary metaphysics" I (...) show that my argument does not presuppose controversial metametaphysical assumptions. (shrink)

One way to challenge the substantiveness of a particular philosophical issue is to argue that those who debate the issue are engaged in a merely verbal dispute. For example, it has been maintained that the apparent disagreement over the mind/brain identity thesis is a merely verbal dispute, and thus that there is no substantive question of whether or not mental properties are identical to neurological properties. The goal of this paper is to help clarify the relationship between mere verbalness and (...) substantiveness. I first argue that we should see mere verbalness as a certain kind of discourse defect that arises when the parties differ as to what each takes to be the immediate question under discussion. I then argue that mere verbalness, so understood, does not imply that the question either party is attempting to address is a non-substantive one. Even if it turns out that the parties to the mind/brain dispute are addressing subtly different questions, these might both be substantive questions to which their respective metaphysical views provide substantive answers. One reason it is tempting to reach deflationary conclusions from the charge of mere verbalness is that we fail to distinguish it from the claim that a sentence under dispute is, in a certain sense, indisputable. Another reason is that we fail to distinguish mere verbalness from a certain sort of indeterminacy. While indisputability and indeterminacy plausibly capture forms of nonsubstantiveness, I argue that mere verbalness is insufficient to establish either indisputability or indeterminacy. (shrink)

Ontological pluralism is the doctrine that there are different ways or modes of being. In contemporary guise, it is the doctrine that a logically perspicuous description of reality will use multiple quantifiers which cannot be thought of as ranging over a single domain. Although thought defeated for some time, recent defenses have shown a number of arguments against the view unsound. However, another worry looms: that despite looking like an attractive alternative, ontological pluralism is really no different than its counterpart, (...) ontological monism. In this paper, after explaining the worry in detail, I argue that considerations dealing with the nature of the logic ontological pluralists ought to endorse, coupled with an attractive philosophical thesis about the relationship between logic and metaphysics, show this worry to be unfounded.

Metaontology – the study of the nature of ontological issues – has flourished in recent years. The focus of this summary will be on some views and arguments that are central to today’s debate. One theme will be that of how seriously to take ontology: whether there is reason to take a skeptical or deflationary attitude toward ontological claims, as theorists like Rudolf Carnap, Hilary Putnam, and Eli Hirsch in different ways have urged. The other theme will be that of (...) the viability of the Fregean and Quinean approaches to ontology that have been and still are central to analytic philosophy. (shrink)

There is currently debate between deflationists and anti-deflationists about the ontology of persisting objects. Some deflationists think that disputes between, for example, four-dimensionalists (e.g. Ted Sider and David Lewis) and quasi-nihilists (e.g. Peter Van Inwagen and Trenton Merricks) are merely verbal disputes. Anti-deflationists deny this. Eli Hirsch is a deflationist who maintains that many ontological disputes are merely verbal. Theodore Sider maintains that the disputes are not merely verbal. Hirsch and Sider are thus engaged in a metaontological dispute. In this (...) paper, I argue that Hirsch's metaontological dispute with Sider is, by Hirsch's own lights, itself merely verbal. I conclude that the mere verbalness of his metaontological dispute with Sider suggests that Hirsch's account of what makes a dispute merely verbal may be problematic. (shrink)

Abstract: There are two traditionally rival views about the nature of time: substantivalism that takes time to be a substance that exists independently of events located in it, and relationism that takes time to be constructed out of events. In this paper, first, I want to make some progress with respect to the debate between these two views, and I do this mainly by examining the strategies they use to face the possibilities of ‘empty time’ and ‘time without change’. As (...) we shall see, the two allegedly very different rival views are much less different than has been thought: their structure is extremely similar, their strategies are extremely similar, and they can both face the possibilities of ‘empty time’ and ‘time without change’ in the same way. Thus, I argue in favour of a certain kind of equivalence between the two views; I discuss a Strong and a Weak version of this claim; and I provide reasons for endorsing the former. I also discuss the parallel between this pair of views about the nature of time and another analogous pair of views: the bundle theory and the substratum theory about the nature of material objects, with respect to the problem with Identity of Indiscernibles.

A presentation of the Lewis-Sider argument from vagueness for unrestricted composition and possible responses.

The common view has it that there are two families of approaches towards the logical structure of impossible worlds – Australasian and North American. According to the first, impossible worlds are closed under the relation of logical consequence of one of the non-classical logics. The North American approach is more liberal, allowing for impossible worlds where no logic holds. After pointing out the questionable consequences of each view, I propose a third one. While this new perspective allows for worlds where (...) no logical consequence holds, it also imposes some constraints on what worlds are built upon. This renders the proposed view not as restrictive as the Australasian approach and not as liberal as the North American approach. Due to its intermediary nature, I have named this perspective ‘the Pacific’ approach. (shrink)

Hirsch advocates a certain kind of metaontological deflationism. He believes that, sometimes, metaphysicians are talking past each other. In his opinion, the debate between compositional organicists and compositional universalists is a prototypical verbal dispute. I argue that his diagnosis is wrong especially with regard to this central case. My argument also weakens his deflationist position in general.

The subject of this article is the Principle of Characterization—the most controversial principle of Alexius Meinong’s Theory of Objects. The aim of this text is twofold. First of all, to show that Bertrand Russell’s well-known objection to the Principle of Characterization can be reformulated against contemporary unrestricted interpretations of it. Second, to propose an alternative formulation of this principle. This refers to the methodology of metaphysics and is based on the distinction between pre-theoretical and theoretical languages. The proposed formulation fits (...) well with every type of contemporary interpretation of the Theory of Objects and helps to overcome Russell’s criticism. (shrink)

The aim of this paper is to explore the view that some ontological disputes are “metalinguistic negotiations”, and to make sense of the significance of these controversies in a way that is still compatible with a broadly deflationist approach. I start by considering the view advocated by Eli Hirsch to the effect that some ontological disputes are verbal. I take the Endurantism–Perdurantusm dispute as a case-study and argue that, while it can be conceded that the dispute is verbal at the (...) object-level, this does not rule out the possibility of a non-verbal disagreement at the metalinguistic level. I then explore the metalinguistic dispute hypothesis by seeing how it can be defended from a first objection playing on the idea of inter-translatability, as well as a second objection raising the question of equal theoretical virtues.

This paper argues that the semantic facts about ‘because’ are best explained via a metaphorical treatment of metaphysical explanation that treats causal explanation as explanation par excellence. Along the way, it defends a commitment to a unified causal sense of ‘because’ and offers a proprietary explanation of grounding skepticism. With the causal metaphor account of metaphysical explanation on the table, an extended discussion of the relationship between conceptual structure and metaphysics ends with a suggestion that the semantic facts about ‘because’ (...) tell against grounding-causation unity.

An encyclopedia entry which covers various revisionary conceptions of which macroscopic objects there are, and the puzzles and arguments that motivate these conceptions: sorites arguments, the argument from vagueness, the puzzles of material constitution, arguments against indeterminate identity, arguments from arbitrariness, debunking arguments, the overdetermination argument, and the problem of the many.

In a series of publications, Eli Hirsch has presented a sustained defense of common-sense ontology. Hirsch's argument relies crucially on a meta-ontological position sometimes known as ‘superficialism’. Hirsch's argument from superficialism to common-sense ontology is typically resisted on the grounds that superficialism is implausible. In this paper, I present an alternative argument for common-sense ontology, one that relies on (what I argue is) a much more plausible meta-ontological position, which I call ‘constructivism’. Note well: I will not quite argue that (...) constructivism is true; merely that it is significantly more plausible than superficialism, and consequently affords a safer route to common-sense ontology. Thus my main goal in the paper is not quite to establish common-sense ontology, nor for that matter to refute Hirsch's argument for it. My goal is, in a way, more expressive than argumentative: I wish to articulate a novel meta-ontological position, one that I take to be in no way obviously less plausible than already familiar positions, and to point out that the position probably leads to common-sense ontology. I open, in section 1, with a discussion of Hirsch's argument and the main objection to it. I then develop, in section 2, a sketch of the alternative meta-ontology I have in mind. I close, in section 3, with the argument that this alternative meta-ontology, too, leads to common-sense ontology. (shrink)

ABSTRACT There has been recent interest in the idea that, when metaphysicians disagree over the truth of (say) ‘There are numbers’ or ‘Chairs exist’, their dispute is merely verbal. This idea has been taken to motivate quantifier variance, the view that the meanings of quantifier expressions vary across different ontological languages, and that each of these meanings is of equal metaphysical merit. I argue that quantifier variance cannot be upheld in light of natural language theorists’ analyses of quantifier expressions. The (...) idea that metaphysicians are engaged in verbal disputes can be maintained only through alternative strategies that have nothing to do with quantifier expressions. (shrink)

It is common to criticize a debate by alleging that it is a “merely verbal dispute.” But how conclusive would an argument based on such allegations be? This article takes the material‐composition debate as a case study and argues that the merely verbal dispute objection is less decisive than one might expect. While assessing the dialectical effectiveness of the mere‐verbality move, the article also tries to mark some progress in the philosophical understanding and appreciation of the phenomenon itself of merely (...) verbal disputes. Its contribution consists in shedding light on a distinction between the “faultlessness” and “faultiness” of a merely verbal dispute. (shrink)

With metaphysical philosophy gaining prominence in the aftermath of the Quine-Carnap debate, not only has it become assumed that the Quinean critique leaves ontological pluralism behind as an untenable approach, but also that the same is true of deflationism more generally. Building on Quine’s criticisms against the analytic-synthetic distinction and the notion of quantifier variance, contemporary metaphysicians like van Inwagen and Sider continue to argue for the untenability of deflationary approaches to metaontology. In this paper I will argue that Quine’s (...) criticisms do not provide sufficient grounds for revitalizing metaphysics, as the aforementioned metaphysicians conceive them as doing, and that they also don’t eliminate all hope for Carnapian pluralism. Furthermore, Carnap’s initial position may even yield the most promising route for the pluralistically inclined. Moreover, pluralism is often conceived as being equivalent with the narrower notion of quantifier variance, often associated with Hirsch and Putnam. As this notion often is attributed not only to Carnap and other pluralists, but also is taken to be an essential feature of deflationism, explicating how their merits in fact don’t necessarily coincide with those of quantifier variance will clarify matters. I will conclude by noting how neither pluralism nor deflationism is committed to quantifier variance, and thus how arguments against the latter don’t entail a refutation of the former. (shrink)

Terms such as ‘exist’, ‘actual’, etc., (hereafter, “ontic terms”) are recognized as having uses that are not ontologically committing, in addition to the usual commissive uses. (Consider, e.g., the Platonic and the neutral readings of ‘There is an even prime’.) In this paper, I identify five different noncommissive uses for ontic terms, and (by a kind of via negativa) attempt to define the commissive use, focusing on ‘actual’ as my example. The problem, however, is that the resulting definiens for the (...) commissive ‘actual’ is itself equivocal between a commissive and a noncommissive reading. I thus consider other proposals for defining the commissive use, including two proposals from David Lewis. However, each proposal is found to be equivocal in the same way—and eventually I argue that it is impossible to define an ontic term unequivocally. Even so, this is not meant to overshadow that we can understand an ontic term as univocally commissive, in certain conversational contexts. I close by illustrating the import of these observations for the Hirsch–Sider debate in metaontology. (shrink)

There are two ways of approaching an ontological debate: ontological realism recommends that metaphysicians seek to discover deep ontological facts of the matter, while ontological anti-realism denies that there are such facts; both views sometimes run into difficulties. This paper suggests an approach to ontology that begins with conceptual analysis and takes the results of that analysis as a guide for which metaontological view to hold. It is argued that in some cases, the functions for which we employ a part (...) of our conceptual scheme might give us reasons to posit ontological facts regarding certain objects. The proposed approach recommends ontological realism about an object just in case our conceptual scheme gives us reason to. This yields a mixed overall metaontological view that adopts ontological realism to some issues and ontological anti-realism to others, and that avoids the difficulties that typically arise for the two views.

In this article I introduce a hybrid view of persistence whereby simple objects persist by enduring while composite objects persist by being stage-related. I first show how, by sharing certain features and not others with the standard views of persistence, this hybrid view navigates two metaphysical problems that have been raised against such standard views. I then consider some implications of the view by addressing a couple of worries that may be raised against it. I conclude that this hybrid view (...) provides an attractive theory, one that deserves further investigation in the debate on persistence. (shrink)

Przedmiotem artykułu jest status ontologiczny światów możliwych oraz niemożliwych. Zgodnie z jedną ze współczesnych wersji meinongianizmu, o ile świat aktualny jest przedmiotem istniejącym, o tyle światy czysto możliwe oraz niemożliwe uznawane są za przedmioty nieistniejące. Zwolennicy tego podejścia twierdzą ponadto, że światom nieaktualnym nie przysługuje żaden inny rodzaj istnienia.Celem artykułu jest wskazanie na problematyczne konsekwencje wspomnianego stanowiska oraz zarysowanie poglądu alternatywnego, który oparty jest na pluralizmie ontologicznym, tj. na poglądzie uznającym wielość rodzajów istnienia.

This article discusses a familiar version of trope theory as opposed to a familiar version of the theory of universals, examining how these two rivals address the problem of “attribute agreement”—a problem that has been at the root of the very reason for developing these theories in the first place. The article shows that there is not much of a difference between the ways these two theories handle the problem, and in a more general way it argues that there is (...) little reason for preferring one theory over the other. It is not interested in this claim only for the sake of the debate between trope theory and the theory of universals. Indeed, the reasons why it claims that it is so difficult to choose one theory over the other can be applied to other cases as well (where they might lead to claims of metaphysical equivalence).
