The paper surveys different notions of implicit definition. In particular, we offer an examination of a kind of definition commonly used in formal axiomatics, which in general terms is understood as providing a definition of the primitive terminology of an axiomatic theory. We argue that such “structural definitions” can be semantically understood in two different ways, namely as specifications of the meaning of the primitive terms of a theory and as definitions of higher-order mathematical concepts or structures. We analyze these (...) two conceptions of structural definition both in the history of modern axiomatics and in contemporary philosophical debates. Based on that, we give a systematic assessment of the underlying semantics of these two ways of understanding the definiens of such definitions, by considering alternative model-theoretic and inferential accounts of meaning.

Until recently, an almost perfect parallelism seemed to hold between theories of identity through time and across possible worlds,as every account in the temporal case(endurantism,perdurantism, exdurantism) was mirrored by a twin account in the modal case (trans-world identity, identity-via-parts, identity-via-counterparts). Nevertheless, in the recent literature, this parallelism has been broken because of the implementation in the debate of the relation of location. In particular, endurantism has been subject to a more in-depth analysis, and different versions of it, corresponding to different (...) ways an entity can be located in time, emerged. In this article, we provide a precise map of the conceptions at stake, complete the debate by introducing a version of endurantism not yet considered in the debate — we call transcendentism — and show that it allows us to provide an effective interpretation of the relation of trans-world identity and an intuitive solution in the temporal case.

Personal time, as opposed to external time, has a certain role to play in the correct account of death and immortality. But saying exactly what that role is, and what role remains for external time, is not straightforward. I formulate and defend accounts of death and immortality that specify these roles precisely.

I defend coincidentalism (the view that some pluralities have more than one mereological fusion) and restricted composition (the view that some pluralities lack mereological fusions) against recent arguments due to Theodore Sider.

Many philosophers have thought that the problem of personal identity over time is not metaphysically deep. Perhaps the debate between the rival theories is somehow empty or is a ‘merely verbal dispute’. Perhaps questions about personal identity are ‘nonsubstantive’ and fit more for conceptual analysis and close attention to usage than for theorizing in the style of serious metaphysics, theorizing guided by considerations of systematicity, parsimony, explanatory power, and aiming for knowledge about the objective structure of the world. I discuss (...) a thesis about consciousness according to which there are perfectly natural phenomenal properties. Although I do not argue for this thesis, I believe that it is plausible, whether or not physicalism is true. Given the thesis, there are deep, substantive questions about which individuals or pluralities instantiate the relevant phenomenal properties. Equally substantive questions can then be asked about the duration and other spatiotemporal characteristics of those individuals or pluralities, both in actual cases and in hypothetical puzzle cases adapted from the personal identity literature. I suggest that, at least prima facie, these questions interact with our future-directed egoistic concern in much the same way that the personal identity question is often thought to. As a slogan: “you give me substantive, determinate facts about consciousness; I give you substantive, determinate facts about personal identity”. (shrink)

Tropes are particular features of concrete objects. Properties—the extensions of predicates—are primitive resemblance classes of tropes. Friends of tropes have been criticized for failing to answer three questions. First, are there fundamental items other than tropes? Second, what criteria determine whether some tropes are all and only the features of some one object? Third, can trope classes be formed adequately using only primitive resemblance? Trading on the spatiotemporal status of tropes, this essay offers new responses to each of these questions. (...) The novel thesis is that there is a sui generis property called ‘markedness’, whose tropes “mark” certain locations in an ontologically basic way. The spatiotemporal distribution of markedness tropes fixes the distribution of familiar characterizing tropes like mass and charge, and characterizing tropes are bundled by being co-contained in the location of a maximally connected markedness trope. This novel theory of trope bundling is defended by appeal to theoretical utility: it is ontologically parsimonious and solves outstanding problems involving co-location and resemblance class construction.

We have two aims in this paper. The first is to provide the reader with a critical guide to recent work on relativity and persistence by Balashov, Gilmore and others. Much of this work investigates whether endurantism can be sustained in the context of relativity. Several arguments have been advanced that aim to show that it cannot. We find these unpersuasive, and will add our own criticisms to those we review. Our second aim, which complements the first, is to demarcate (...) the most defensible form of relativistic endurantism. A recurring theme of this paper is that even those philosophers who do worry about relativity have not taken it seriously enough. (shrink)

According to the cluster of theories in the metaphysics of properties known as ‘trope’ theories, properties are collections of particular qualitative instances. Though increasingly influential, the cluster is sufficiently diverse for there to be little agreement as to the prospects of its members. The present essay articulates and defends a conception of tropes as primitively qualitatively complex, somewhat in the vein of Quinean nominalist objects. After clarifying the relationships among tropes, properties, property exemplification, and property conferral, the essay discusses the (...) benefits of this new ‘ostrich’ trope theory. Specifically, the theory explains better than prior trope theories both the spatiotemporal status of tropes and the capacity tropes have to confer properties onto objects. Moreover, the theory is immune to many of the concerns that threaten more orthodox trope ontologies. (shrink)

A mereological structure is junky if and only if each of its elements is a proper part of some other. The young literature on junk has focused on junky worlds and whether they are counterexamples to unrestricted composition. The present note defends the possibility of junky structures that are not worlds. This possibility complicates a recent attempt in the literature to render junk consistent with a weakened form of unrestricted composition. The upshot is that junky non-worlds threaten the weakened form (...) of unrestricted composition as much as junky worlds threaten the traditional version. (shrink)

Evaluating counterfactuals in worlds with deterministic laws poses a puzzle. In a wide array of cases, it does not seem plausible that if a non-actual event were to occur that either the past would be different or that the laws would be different. But it’s also difficult to see how we can avoid this result. Some philosophers have argued that we can avoid this dilemma by allowing that a proposition can be a law even though it has violations. On this (...) view, for the relevant cases, the past and the laws would still hold, but the laws would have a violation. In this paper, I raise a problem for the claim that the laws and the past are preserved for all of the relevant counterfactual antecedents. I further argue that this problem undermines motivating the possibility of violations on the grounds that they allow us to hold that the past and the laws are typically counterfactually preserved, even if they are not always preserved. (shrink)

Causal essentialists hold that a property essentially bears its causal and nomic relations. Further, as many causal essentialists have noted, the main motivations for causal essentialism also motivate holding that properties are individuated in terms of their causal and nomic relations. This amounts to a kind of identity of indiscernibles thesis; properties that are indiscernible with respect to their causal and nomic relations are identical. This can be compared with the more well-known identity of indiscernibles thesis, according to which particulars (...) that are qualitatively indiscernible are identical. Robert Adams has developed a well-known objection to this thesis by considering a series of possibilities involving nearly qualitatively indiscernible particulars that naturally leads to a possibility involving qualitatively indiscernible particulars. I argue that we can construct parallel cases involving a series of possibilities involving properties that are nearly indiscernible with respect to their causal and nomic relations that naturally lead to possibilities involving properties that are indiscernible with respect to their causal and nomic relations. The same features that make Adams’ argument forceful also carry over to my cases, giving us a powerful objection to the causal essentialist identity of indiscernibles thesis. (shrink)

One premise in David Lewis’s well-known argument from temporary intrinsic properties in favor of temporal parts is the intuition that material objects exemplify such properties simpliciter, that is, without qualification. The argument has spawned a large critical literature, with commentators questioning the simpliciter premise’s motivation, content, dialectical force, and status as an intuition. The present essay has two chief goals: to provide a novel framework for clarifying Lewis’s simpliciter premise and to explain how the resulting clarification upends a wide range (...) of attempts in the literature to evade his conclusion. Central to both goals is the observation that exemplification simpliciter best comports with our most fundamental notion of property exemplification, a notion that applies equally well to material and atemporal abstract objects. (shrink)

We have compelling extra-philosophical reasons for caring about identity, parthood, and location. For example, we desire ceteris paribus that nothing every part of which is very near to our location be very near to the location of something dangerous, evil, or otherwise unpleasant. This essay argues that such considerations are relevant to certain first-order metaphysical debates, namely, the debates over immanent universals and tropes and endurantism and perdurantism, respectively. As a consequence, even the non-specialist has a reason to care about (...) the metaphysics of properties and persistence. (shrink)

A modus tollens against zero-dimensional material objects is presented from the premises (i) that if there are zero-dimensional material objects then there are bare particulars, and (ii) that there are no bare particulars. The argument for the first premise proceeds by elimination. First, bare particular theory and bundle theory are motivated as the most appealing theories of property exemplification. It is then argued that the bundle theorist’s Ockhamism ought to lead her to reject spatiotemporally located zero-dimensional property instances. Finally, it (...) is argued that since she must accept such instances if she accepts zero-dimensional material object bundles, she ought to avoid the latter. This leaves bare particular theory as the default view of zero-dimensional material objects. The argument for the second premise invokes the thesis that the exemplification of at least one sparse property is a prerequisite for the existence of any particular. It is argued from Humean considerations that bare particulars fail this prerequisite. (shrink)

Dispositional essentialism is the view that all or many fundamental properties are essentially dispositional, orpowers. The literature on the dispositional essence of powers is abundant. In contrast, the question of how to understand the fundamentality of fundamental powers has received scarce interest. Therefore, the fundamentality of powers stands in need of clarification. There are four main conceptions of the fundamental, namely as that which is (i)metaphysically independent; or (ii)belonging to a minimally complete basis; or (iii)perfectly natural; or (iv)metaphysically primitive. Here, (...) I present and discuss each of these approaches from the viewpoint of dispositional essentialism. I show that (i) is incompatible with the metaphysics of powers and (ii)–(iv) have more drawbacks than merits. Therefore, my conclusion is that the dispositional essentialist should seek an alternative. Although I offer no positive account, I pave the way to more fruitful views by identifying the shortcoming of these unpromising options. (shrink)

Dispositionality and qualitativity are key notions to describe the world that we inhabit. Dispositionality is a matter of what a thing is disposed to do in certain circumstances. Qualitativity is a matter of how a thing is like. According to the Identity Theory of powers, every fundamental property is at once dispositional and qualitative, or a powerful quality. Canonically, the Identity Theory holds a contentious identity claim between a property’s dispositionality and its qualitativity. In the literature, this view faces a (...) contradiction objection that undermines its merits. We should therefore consider an alternative version that does not embrace the identity claim. My aim is to show that we can enjoy the benefits of the Identity Theory without embracing the identity between the dispositional and the qualitative. I shall argue that a distinction between two senses of dispositionality and qualitativity serves the purpose. I will then discuss three readings of the identity claim that can be formulated in light of such a distinction. I will conclude that even if the identity were to fail in any of the suggested readings, it would be possible to hold an account of fundamental powerful qualities. (shrink)

In this paper I argue that even the most radical metaphysics of powers (such as that adopted by Mumford & Anjum, Cartwright, or Groff) are compatible with eternalism. I first offer a taxonomy of powers ontologies, and attempt to characterise the difference between moderate and radical powers ontologies – the latter are characterised by an emphasis on production and dynamicity. I consider an argument by C. Friebe to the effect that the productive character of powers is inconsistent with Eternalism and (...) find it wanting. I then elucidate the notion of dynamicity that radical powers theorists employ by making apparent their link with an ontology of irreducible processes. Finally, I respond to an argument by Donatella Donati to the effect that eternalism entails a reductive account of change which is inconsistent with process ontologies, and show that the the two are compatible. I conclude that we have no reason to think that radical powers metaphysics (and, a fortiori, every powers ontology) are not compatible with eternalism. (shrink)

This paper consists of two main parts and a coda. In the first part I present the ''binding theory'' of presupposition projection, which is the framework that I adopt in this paper (Section 1.1). I outline the main problems that arise in the interplay between presuppositions and anaphors on the one hand and attitude reports on the other (Section 1.2), and discuss Heim''s theory of presuppositions in attitude contexts (Section 1.3).In the second part of the paper I present my own (...) proposal. To begin with, I define an extension of DRT in which attitude reports can be represented (Sections 2.1–2.2). I then argue that the verb believe triggers a certain presupposition and that, given the binding theory, this presupposition determines the projection behaviour of the verb (Section 2.3). This analysis yields predictions which are incomplete in the sense that they do not fully account for speakers'' intuitions about presuppositions and anaphors in belief contexts. In Section 2.4 I suggest that this is as it should be because we may assume on independent grounds that there is a class of plausibility inferences which complement the predictions of the presupposition theory. Finally, the analysis is extended to the verb want (Section 2.5). (shrink)

Within a literary ontology, YHWH in the Hebrew Bible is technically also a fictional entity or object. In Hebrew Bible scholarship, a variety of philosophical issues surrounding fiction have received sustained and in-depth attention. However, the mainstream research on these matters tends to focus on the philosophical foundations of or backgrounds to a particular literary theory, rather than on metaphysical puzzles as encountered in the philosophy of fiction proper. To fill this gap, the present article seeks to provide a meta-theoretical (...) overview of the main contemporary philosophical perspectives on the metaphysics of fictional objects. Three views are discussed, namely possibilism, Meinongianism and creationism. Each view's theory is introduced and critically appropriated with reference to what is implied to be an answer to the question of what exactly the biblical character YHWH can meaningfully be said to be in the context of the metaphysics of fictional objects. In this way, the present study also goes beyond the traditional concern with the nature of God in Old Testament theology. (shrink)

Theories of propositions as sets of truth-supporting circumstances are committed to the thesis that sentences or other representations true in all and only the same circumstances express the same proposition. Theories of propositions as complex, structured entities are not committed to this thesis. As a result, structured propositions can play a role in our theories of language and thought that sets of truth-supporting circumstances cannot play. To illustrate this difference, I sketch a theory of transparent, non-deflationary truth consistent with some (...) theories of structured propositions, but inconsistent with any theory of propositions as sets of truth-supporting circumstances.

I start by way of clarifying briefly the problem of special divine intervention. Once this is done, I argue that laws of nature are generalizations that derive from the dispositional behaviour of natural kinds. Based on this conception of laws of nature I provide a metaphysical model according to which God can realize acts of special divine providence by way of temporarily changing the dispositions of natural entities. I show that this model does not contradict scientific practice and is consistent (...) with the assumption that the physical realm is causally closed. I then argue that prima facie any putative candidate for an act of God could also be seen as a random event or as indicating that there is something wrong with our formulation of the corresponding law of nature. While there is no sufficient philosophical or scientific reason to prefer one of these models, I argue that there are sufficient and legitimate theological reasons to endorse a framework in which at least the obtaining of some anomic states of affairs is seen as the effect of special divine intervention. Doing so, theology has the hermeneutic resources to uncover a dimension of meaningful reality, which without faith could not be seen. (shrink)

There is little doubt that we perceive the world as tensed—that is, as consisting of a past, present and future each with a different ontological status—and transient—that is, as involving a passage of time. We also have the ability to execute precisely timed behaviors that appear to depend upon making correct temporal judgments about which changes are truly present and which are not. A common claim made by scientists and philosophers is that our experiences of entities enduring through transient changes (...) are illusory and that our apparently accurately timed behaviors do not reflect dynamical time. We argue that our experiences of objects enduring through transient changes need not be thought of as illusory even if time is not dynamic at the fundamental level of reality. For, the dynamic properties we experience objects as having need not be fundamental properties. They could be weakly emergent from static, temporal properties. Temporal properties, on this view, are similar to ordinary properties like that of being solid, which are correctly experienced as properties of medium-sized material bodies even though they are not instantiated at the fundamental level of reality.

Panenetheism is the claim that God and the cosmos are intimately inter-related, with the cosmos being in God and God being in the cosmos. What does this exactly mean? The aim of this paper is to address this question by sheding light on four possible models of God-world-inter-relatedness. Being critical of those models, which understand maximal immanence in a literal, spatial sense, the paper argues in favor of a model, which cashes out immanence in terms of divine activity. God is, (...) where God acts. Since God acts upon all of creation everywhere and anytime, God is omnipresent to it at all times. Thus, the proposal is to read the ‘en’ in ‘panetheism’ in an ‘agential sense’: God is in the cosmos by creating and sustaining it and the cosmos is in God by constantly being within the sphere of divine activity.

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)

The paper surveys recent appraisals of David Lewis’s seminal paper on truth in fiction. It examines variations on standard criticisms of Lewis’s account, aiming to show that, if developed as Lewis suggests in his 1983 Postscript A, his proposals on the topic are—as Hanley puts it—‘as good as it gets’. Thus elaborated, Lewis’s account can resist the objections, and it offers a better picture of fictional discourse than recent resurrections of other classic works of the 1970s by Kripke, van Inwagen (...) and Searle. The turn that Lewis suggests and the paper recommends draws on the remaining outstanding contribution from that time: Walton’s. (shrink)

Abstract Non-reductive physicalism is currently the most widely held metaphysic of mind. My aim in this essay is to show that supervenience physicalism?perhaps the most common form of non-reductive physicalism?is not a defensible position. I argue that, in order for any supervenience thesis to ground a legitimate form of physicalism, it must yield the right sort of determination relation between physical and non-physical properties. Then I argue that non-reductionism leaves one without any explanation for the laws that are implied by (...) supervenience theses that deliver this determination relation. (shrink)

This article argues for two related theses. First, it defends a general thesis: any kind of necessity, including metaphysical necessity, can only be known a priori. Second, however, it also argues that the sort of a priori involved in modal metaphysical knowledge is not related to imagination or any sort of so-called epistemic possibility. Imagination is neither a proof of possibility nor a limit to necessity. Rather, modal metaphysical knowledge is built on intuition of philosophical categories and the structures they (...) form.

We present here the papers selected for the volume on the Unity of Propositions problems. After summarizing what the problems are, we locate them in a spectrum from those aiming to provide substantive, reductive explanations, to those with a more deflationary take on the problems.

The thesis of this paper is that the capacity to think of one’s perceptions as cross-modally integrated is incompatible with a reductionist account of the self. In §2 I distinguish three versions of the argument from cross-modality. According to the ‘unification’ version of the argument, what needs to be explained is one’s capacity to identify an object touched as the same as an object simultaneously seen. According to the ‘recognition’ version, what needs to be explained is one’s capacity, having once (...) seen an object, to reidentify that same object by touch alone. According to the ‘objectivity’ version, what needs to be explained is one’s capacity to think of one’s perceptions in different modalities as perceptions of one and the same object. The third version seems to establish that one must conceive of oneself substantially, as the numerically identical owner of one’s experiences, a conclusion in agreement with recent work in developmental psychology claiming to show that an infant’s cross-modal capacities are essentially implicated in their development of a sense of self. There is further work to be done if this is to be tumed into an argument against reductionism: there is no swift route from the epistemology of self-consciousness to the metaphysics of the self. In the §3, I will claim that there is, nevertheless, an argument linking the two. What I propose is an argument derived, not from the token-reflexive rule for the first-person, but resting on its anaphoric behaviour spanning intensional operators. (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.

Monists say that the nature of truth is invariant, whichever sentence you consider; pluralists say that the nature of truth varies between different sets of sentences. The orthodoxy is that logic and logical form favour monism: there must be a single property that is preserved in any valid inference; and any truth-functional complex must be true in the same way as its components. The orthodoxy, I argue, is mistaken. Logic and logical form impose only structural constraints on a metaphysics of (...) truth. Monistic theories are not guaranteed to satisfy these constraints, and there is a pluralistic theory that does so. (shrink)

The purpose of this paper is to provide a new system of logic for existence and essence, in which the traditional distinctions between essential and accidental properties, abstract and concrete objects, and actually existent and possibly existent objects are described and related in a suitable way. In order to accomplish this task, a primitive relation of essential identity between different objects is introduced and connected to a first order existence property and a first order abstractness property. The basic idea is (...) that possibly existent objects are completely determinate and that essentially identical objects are just different individuations of the same individual essence. Accordingly, essential properties are defined as properties that are invariant with respect to this kind of identity, while abstract objects are determined by being characterized by essential properties only. Once such ideas are implemented, a number of classical intuitions about objects, their essence, and their way of existence can be consistently interpreted. (shrink)

A central tension shaping metaethical inquiry is that normativity appears to be subjective yet real, where it’s difficult to reconcile these aspects. On the one hand, normativity pertains to our actions and attitudes. On the other, normativity appears to be real in a way that precludes it from being a mere figment of those actions and attitudes. In this paper, I argue that normativity is indeed both subjective and real. I do so by way of treating it as a special (...) sort of artifact, where artifacts are mind-dependent yet nevertheless can carve at the joints of reality. In particular, I argue that the properties of being a reason and being valuable for are grounded in attitudes yet are still absolutely structural. (shrink)

We develop a theory about the metaphysics of time and modality that combines the conceptual resources devised in recent sympathetic work on ontological pluralism (the thesis that there are fundamentally distinct kinds of being) with the thought that what is past, future, and merely possible is less real than what is present and actual (albeit real enough to serve as truthmakers for statements about the past, future, and merely possible). However, we also show that despite being a coherent, distinctive, and (...) prima facie appealing position, the theory succumbs to what we call the “problem of mixed ontological status”. We conclude that the proponents of the theory can only evade these problems by developing ontological pluralism in a radically different way than it has been by its recent sympathizers. (shrink)

I explain a tension between musical creationism (the view that musical works are abstract artifacts) and the view that there is no vague existence. I then suggest ways to reconcile these views. My central conclusion is that, although some versions of musical creationism imply vague existence, others do not. I discuss versions of musical creationism held by Jerrold Levinson, Simon Evnine, and Kit Fine. I also present two new versions. I close by considering whether the tension is merely an instance (...) of a general problem raised by artifacts, both abstract and concrete. I argue that on at least one defensible account of music the tension is especially problematic for abstracta. I focus on musical works, but much of the paper straightforwardly applies to other kinds of abstract artifacts. (shrink)

Two expressive limitations of an infinitary higher-order modal language interpreted on models for higher-order contingentism – the thesis that it is contingent what propositions, properties and relations there are – are established: First, the inexpressibility of certain relations, which leads to the fact that certain model-theoretic existence conditions for relations cannot equivalently be reformulated in terms of being expressible in such a language. Second, the inexpressibility of certain modalized cardinality claims, which shows that in such a language, higher-order contingentists cannot (...) express what is communicated using various instances of talk of ‘possible things’, such as ‘there are uncountably many possible stars’.

Beach's Gaelic Symphony is plausibly an abstract object that Beach created. The view that people create some abstract objects is called abstract creationism. There are abstract creationists about many kinds of objects, including musical works, fictional characters, arguments, words, internet memes, installation artworks, bitcoins, and restaurants. Alternative theories include materialism and Platonism. This paper discusses some of the most serious objections against abstract creationism. Arguably, these objections have ramifications for questions in metaphysics pertaining to the abstract/concrete distinction, time, causation, vague (...) existence, vague identity, and inadvertent creation.

It has been suggested that quantum particles are genuinelyvague objects (Lowe 1994a). The present work explores thissuggestion in terms of the various metaphysical packages that areavailable for describing such particles. The formal frameworksunderpinning such packages are outlined and issues of identityand reference are considered from this overall perspective. Indoing so we hope to illuminate the diverse ways in whichvagueness can arise in the quantum context.

In Parts of Classes David Lewis argued that mereology is ‘ontologically innocent’, mereological notions not incurring additional ontological commitments. Unfortunately, though, Lewis’s argument for this is not fully spelled out. Here we use some formal results concerning translations between formal languages to argue for the ontological innocence of mereology directly.

I argue that, for all we know, there are perfectly ordinary actual entities that are temporal in the usual sense and yet never present, past, or future. This epistemic fact requires us to modify the theses of presentism and eternalism. More importantly, it generates three new and quite serious objections to presentism, which I formulate and partially evaluate in this paper.

Content externalism is the dominant view in the philosophy of mind. Content essentialism, the thesis that thought tokens have their contents essentially, is also popular. And many externalists are supporters of such essentialism. However, endorsing the conjunction of those views either (i) commits one to a counterintuitive view of the underlying physical nature of thought tokens or (ii) commits one to a slightly different but still counterintuitive view of the relation of thought tokens to physical tokens as well as a (...) rejection of realist physicalism. In this essay I reveal the problem and articulate and adjudicate among the possible solutions. I will end up rejecting content essentialism. (shrink)

Hud Hudson has argued that if MaxCon, Ned Markosian's favored answer to the Simple Question, is true, then there couldn't be gunky objects. If Hudson's argument succeeds, then those who believe that gunky objects are possible have a good reason to reject MaxCon. However, I show that Hudson's argument relies on substantive metaphysical claims that a proponent of MaxCon need not accept. Thus, one who endorses MaxCon need not reject the possibility of gunky objects and those who believe that gunky (...) objects are possible need not reject MaxCon. (shrink)

William Rowe in his Can God be Free? argues that God, if there is a God, necessarily chooses the best. Combined with the premise that there is no best act of creation, this provides an a priori argument for atheism. Rowe assumes that necessarily God is a ‘morally unsurpassable’ being, and it is for that reason that God chooses the best. In this article I drop that assumption and I consider a successor to Rowe ’s argument, the Argument from Arbitrariness, (...) based on the premise that God does not act arbitrarily. My chief conclusion will be that this argument fails because, for all we know, there can be non- arbitrary divine choices even if there is no best act of creation. (shrink)

David Armstrong in his A Combinatorial Theory of Possibility proposes that non-actual possibilities may be treated as fictions grounded in instantiated universals. In this paper, I first provide some objections to his theory. Then I make the case for Foundational Nominalism, the Armstrong inspired thesis that the whole of ontology supervenes on particulars described much as in the Quinean Nominalism that Armstrong rejected as an ontological ostrich. Finally, I argue that Foundational Nominalism permits a fictional theory of possibilities similar to (...) Brian Skyrms’ Tractarian Nominalism. (shrink)

Consider the things that exist—the entities—and let us suppose they are mereologically structured, that is, some are parts of others. The project of ontology within the bounds of bare mereology use this structure to say which of these entities belong to various ontological kinds, such as properties and particulars. My purpose in this paper is to defend the most radical section of the project, the mereological theory of the exemplification of universals. Along the way I help myself to several hypotheses: (...) the existence of merely possible worlds; that particulars have thisnesses; and that mereology is far from classical. Moreover, the way I characterize instantiation might be judged too complicated to be plausible. At the end of the paper, I reply to these objections based on complexity. (shrink)

It is acknowledged by proponents of the Artifactual Theory of Fiction that literary works sometimes involve real or immigrant characters. However, their conception of cross-fictional identity faces serious difficulties. In this paper, we set the problem in the context of a modal framework, in relation to quantification across a plurality of possible worlds. Quantification is explained in terms of Hintikka’s notion of world lines; i.e. the possible values of bound variables are individuals that are not reduced to their manifestations. We (...) finally offer another understanding of identity across weakly impermeable domains, in a way compatible with the Artifactual Theory of Fiction. (shrink)
