The Problem of Overlappers is a puzzle about what makes it the case, and how we can know, that we have the parts we intuitively think we have. In this paper, I develop and motivate an overlooked solution to this puzzle. According to what I call the self-making view it is within our power to decide what we refer to with the personal pronoun ‘I’, so the truth of most of our beliefs about our parts is ensured by the very (...) mechanism of self-reference. Other than providing an elegant solution to the Problem of Overlappers, the view can be motivated on independent grounds. It also has wide-ranging consequences for how we should be thinking about persons. Among other things, it can help undermine an influential line of argument against the permissibility of elective amputation. After a detailed discussion and defence of the self-making view, I consider some objections to it. I conclude that none of these objections is persuasive and we should at the very least take seriously the idea that we are to some extent self-made. (shrink) | |
The paper presents a dilemma for both epistemic and non-epistemic versions of conceivability-based accounts of modal knowledge. On the one horn, non-epistemic accounts do not elucidate the essentialist knowledge they would be committed to. On the other, epistemic accounts do not elucidate everyday life de re modal knowledge. In neither case, therefore, do conceivability accounts elucidate de re modal knowledge. | |
Necessitism is the view that necessarily everything is necessarily something; contingentism is the negation of necessitism. The dispute between them is reminiscent of, but clearer than, the more familiar one between possibilism and actualism. A mapping often used to ‘translate’ actualist discourse into possibilist discourse is adapted to map every sentence of a first-order modal language to a sentence the contingentist (but not the necessitist) may regard as equivalent to it but which is neutral in the dispute. This mapping enables (...) the necessitist to extract a ‘cash value’ from what the contingentist says. Similarly, a mapping often used to ‘translate’ possibilist discourse into actualist discourse is adapted to map every sentence of the language to a sentence the necessitist (but not the contingentist) may regard as equivalent to it but which is neutral in the dispute. This mapping enables the contingentist to extract a ‘cash value’ from what the necessitist says. Neither mapping is a translation in the usual sense, since necessitists and contingentists use the same language with the same meanings. The former mapping is extended to a second-order modal language under a plural interpretation of the second-order variables. It is proved that the latter mapping cannot be. Thus although the necessitist can extract a ‘cash value’ from what the contingentist says in the second-order language, the contingentist cannot extract a ‘cash value’ from some of what the necessitist says, even when it raises significant questions. This poses contingentism a serious challenge. (shrink) | |
It is standardly assumed that there are three — and only three — ways to solve problem of temporary intrinsics: (a) embrace presentism, (b) relativize property possession to times, or (c) accept the doctrine of temporal parts. The first two solutions are favoured by endurantists, whereas the third is the perdurantist solution of choice. In this paper, I argue that there is a further type of solution available to endurantists, one that not only avoids the usual costs, but is structurally (...) identical to the temporal-parts solution preferred by perdurantists. In addition to providing a general characterization of this new type of solution, I discuss certain of its anticipations in the literature on bundle theory, as well as provide a detailed development of it in terms of my own preferred metaphysics of ordinary objects — namely, a distinctive form of substratum theory tracing to Aristotle.

The main goal of this paper is to work out Quine's account of explication. Quine does not provide a general account but considers a paradigmatic example which does not fit other examples he claims to be explications. Besides working out Quine's account of explication and explaining this tension, I show how it connects to other notions such as paraphrase and ontological commitment. Furthermore, I relate Quinean explication to Carnap's conception and argue that Quinean explication is much narrower because its main (...) purpose is to be a criterion of theory choice. (shrink) | |
I begin by contrasting three approaches one can take to the distinction between the essential and accidental properties: an ontological, a deflationary, and a mind‐dependent approach. I then go on to apply that distinction to the necessary a posteriori, and defend the deflationist view. Finally I apply the distinction to modal truth in general and argue that the deflationist position lets us avoid an otherwise pressing problem for the actualist: the problem of accounting for the source of modal truth. | |
Presentism states that everything is present. Crucial to our understanding of this thesis is how we interpret the ‘is’. Recently, several philosophers have claimed that on any interpretation presentism comes out as either trivially true or manifestly false. Yet, presentism is meant to be a substantive and interesting thesis. I outline in detail the nature of the problem and the standard interpretative options. After unfavourably assessing several popular responses in the literature, I offer an alternative interpretation that provides the desired (...) result. This interpretation is then used to clarify the distinction between ‘real change’ from mere variation and temporal relativisation. Reflecting on my solution, I try to diagnose the source of confusion over these issues. Then, building upon Fine’s distinction between ontic and factive presentism, I elucidate what the presentist thesis specifically concerns and how best to formalise it. In the process I distinguish a weak and strong version of the presentist thesis. Finally, I end by drawing out some limitations of the paper. (shrink) | |
I attempt to meet some criticisms that Williamson makes of my attempt to carry out Prior's project of reducing possibility discourse to actualist discourse. | |
What is possible, according to the empiricist conception, is what our evidence positively allows; and what is necessary is what it compels. These notions, along with logical possibility, are the only defensible notions of possibility and necessity. In so far as nomic and metaphysical possibilities are defensible, they fall within empirical possibility. These empirical conceptions are incompatible with traditional possible world semantics. Empirically necessary propositions cannot be defined as those true in all possible worlds. There can be empirical possibilities without (...) empirical necessities. The duality of possibility and necessity can be degenerate and can even be falsified. (shrink) No categories | |
Sortal concepts are at the center of certain logical discussions and have played a significant role in solutions to particular problems in philosophy. Apart from logic and philosophy, the study of sortal concepts has found its place in specific fields of psychology, such as the theory of infant cognitive development and the theory of human perception. In this monograph, different formal logics for sortal concepts and sortal-related logical notions are characterized. Most of these logics are intensional in nature and possess, (...) in addition, a bidimensional character. That is, they simultaneously represent two different logical dimensions. In most cases, the dimensions are those of time and natural necessity, and, in other cases, those of time and epistemic necessity. Another feature of the logics in question concerns second-order quantification over sortal concepts, a logical notion that is also represented in the logics. Some of the logics adopt a constant domain interpretation, others a varying domain interpretation of such quantification. Two of the above bidimensional logics are philosophically grounded on predication sortalism, that is, on the philosophical view that predication necessarily requires sortal concepts. Another bidimensional logic constitutes a logic for complex sortal predicates. These three sorts of logics are among the important novelties of this work since logics with similar features have not been developed up to now, and they might be instrumental for the solution of philosophically significant problems regarding sortal predicates. The book assumes a modern variant of conceptualism as a philosophical background. For this reason, the approach to sortal predicates is in terms of sortal concepts. Concepts, in general, are here understood as intersubjective realizable cognitive capacities. The proper features of sortal concepts are determined by an analysis of the main features of sortal predicates. Posterior to this analysis, the sortal-related logical notions represented in the above logics are discussed. There is also a discussion on the extent to which the set-theoretic formal semantic systems of the book capture different aspects of the conceptualist approach to sortals. These different semantic frameworks are also related to realist and nominalist approaches to sortal predicates, and possible modifications to them are considered that might represent those alternative approaches.

Physical information is a property of nature. How does physical information persist over time? Does it do so as an object, process, or event, which are things considered in the current persistence theories? Physical information is none of these, however, this implies that persistence theories cannot explain the persistence of information. We therefore study the persistence of snowflakes, ephemeral natural structures, to better understand the persistence of natural things, such as physical information. The transitory nature of snowflakes suggests that physical (...) information persists as nature’s latent order, therefore, it is associated with natural structures, but it is not identical to them. This interpretation preserves the properties attributed to physical information, particularly its foundational character. The concept of physical information as latent order accords with Burgin’s General Theory of Information (GTI), which is currently the most comprehensive conceptualization of information that has been proposed.

In this paper, I argue that how a mind can come to be about an object and how the world is independently of the workings of any mind are inextricably linked. Hence, epistemology, at its most basic, and metaphysics are systematically related. In order to demonstrate the primary thesis of the paper, I first articulate two contrary accounts of the nature of reality and then two contradictory general views of intentionality. I argue that these positions can be combined in only (...) two ways. This argument turns on the impossibility of there being an object that cannot, in principle, be thought of or referred to, so I present reasons for thinking such a thing cannot exist. The upshot is that there are but two intentional-cum-ontological positions, that is, two unified positions regarding how a mind relates to the world and what the world is like in itself. This might be surprising, for one might have thought that the views in the different domains were independent; it is significant, because it shows that views that might have seemed related by mere affinity are, in fact, necessarily conjoined. I conclude by presenting reasons for thinking one of the two intentional-cum-ontological positions is untenable. (shrink) | |
The problem of act individuation is a debate about the identity conditions of human acts. The fundamental question about act individuation is: how do we distinguish between actions? Three views of act individuation have dominated the literature. First, Donald Davidson and G.E.M. Anscombe have argued that a number of different descriptions refer to a single act. Second, Alvin Goldman and Jaegwon Kim have argued that each description designates a distinct act. Finally, Irving Thalberg and Judith Jarvis Thomson have averred that (...) some acts are sequences of causally related events, which include both a primitive bodily action and some of its effects. All of these accounts have assumed that a simple invariantist account of act individuation captures how ordinary people distinguish between acts. For my dissertation, I devised an experiment to test the action theorists' assumptions. My data show that people's intuitions seem to depend on the valence of the consequences of the action under consideration. So, an invariantist account is not possible. In light of the empirical results, I argue that if we seek a folk account of act individuation, then that account should be able to explain the variability that seems to be present in people's intuitions about different cases.

Philosophers view themselves as critical thinkers par excellence. But they have overlooked the institutional arrangements that govern their lives. The early twentieth-century research university disciplined philosophers, placing them in departments, where they wrote for and were judged by their disciplinary peers. Oddly, this change has been unremarked upon, or has been treated as simply part of the necessary professionalization of an academic field of research. The department has been tacitly assumed to be a neutral space from which thought germinates; it (...) is not itself an object of reflection. We find no explorations of the effects that departmentalization might have on philosophical theorizing, or speculations about where else philosophers could be housed, or how, by being located elsewhere, they might develop alternative accounts of the world or have come up with new ways of philosophizing.

In this paper I argue that reading history of physics as a contribution to history of philosophy is important for contemporary philosophy of physics. My argument centers around a particular case: special relativity versus presentism. By means of resources drawn from reading aspects of Newton's work as contributions to philosophy, I argue that there is in physics an alternative way to approach what we mean by "present" such that presentism remains an open empirical question whose refutation requires resources that go (...) beyond those of special relativity. I offer this as an example of one fruitful way in which we pursue integrated HPS. (shrink) | |
Substance dualism is the view that there are two fundamentally different kinds of substances: physical and mental. By contrast, according to property dualism there is only one kind of substance (physical) but two fundamentally different kinds of properties: physical and mental. Property nominalism is the view that there are neither repeatable nor non-repeatable fundamentally predicable entities (i.e. neither universals nor tropes) and that things being a certain way or being related in a certain way must ultimately be accounted for in (...) terms of concrete particulars. In this paper, we consider a number of different kinds of property nominalism and argue that none of them sits well with property dualism. We pay special attention to the question of what it could mean for a property to count as mental given different nominalistic accounts of properties. Our conclusion is that property nominalism and property dualism are not a stable match. This is surprising, since property dualism has usually been understood as a thesis that is neutral about the nature of fundamental ontological categories and the relation between them. (shrink) | |
George Molnar’s contention that some dispositional properties are displayed without the aid of any activating conditions poses a challenge to the conditional analysis of dispositions. Since the invocation of activating conditions is regarded as a crucial feature of the analysis, spontaneous dispositions are believed to expose its inadequacy by eluding its scope. The challenge goes to the very heart of the conditional approach to dispositions, allegedly revealing a deep flaw in all its incarnations. Granting that there may be spontaneously manifestable (...) dispositions, I argue that the conditional analysis can successfully accommodate them by elevating the potential causal relation between a disposition and its manifestation.

Scott Aiken and Thomas Dabay contend that a satisfactory account of truth is both infallibilist and antiskeptical. Externalist correspondence theories, they say, preserve the infallibility of the truth-relation yet invite skeptical qualms. In tying truth to experience, pragmatist theories resist skeptical challenges, but embrace a fallibilism that renders their account of truth inconsistent and even incoherent. While agreeing with Aiken and Dabay that externalist accounts are vulnerable to skepticism, I dispute each of the four arguments they offer against pragmatist fallibilism. (...) Though partially successful against Peirce’s more popular view that truth is the final belief of a community of inquirers, their arguments are wholly ineffective against Dewey’s account of truth as warranted assertability.

This is an attempt to sort out what is it that makes many of us uncomfortable with the perdurantist solution to the problem of change. Lewis argues that only perdurantism can reconcile change with persistence over time, while neither presentism nor endurantism can. So, first, I defend the endurantist solution to the problem of change, by arguing that what is relative to time are not properties, but their possession. Second, I explore the anti-perdurantist strategy of arguing that Lewis cannot solve (...) the problem of change, for he cannot account for how some properties are possessed by objects in time. However, I argue that this strategy fails, for if by saying that objects in time can have properties ‘timelessly’ we mean “at no particular time” and “tenselessly”, only objects outside time can have properties in that way; but if we mean “for all the time they exist”, or “essentially”, perdurantists can account for this. Finally, I argue that actually perdurantism cannot solve the problem, but for different reasons: for either it sweeps the problem under the carpet, denying change, and in general subverting our conceptual scheme in a dangerous way, or it becomes equivalent to the endurantist picture that properties are had at times. Nor perdurantism is justified by the Relativity Theory or the B-theory of time, because while endurantism is certainly comfortable with presentism, it need not be committed to it; and even if it were, presentism need not be refuted by the Relativity Theory.

I explain why the compositionalist conception of ordinary objects prevalent in contemporary metaphysics places the manifest image of the human self in a precarious position: the two theoretically simplest views of the existence of composites each jeopardize some central element of the manifest image. I present an alternative, nomological conception of ordinary objects, which secures the manifest image of the human self without the arbitrariness that afflicts compositionalist attempts to do the same. I close by sketching the consequences of the (...) recommended position for the traditional personal identity debate about the nature and persistence of human selves. (shrink) | |

Here is a problem at the heart of the metaphysics of the natural world: How, if at all, can a unity undergo change? This problem incorporates two questions. First, in virtue of what is a thing a genuine unity? And second, the issue that’s more obvious in the formulation of the question: how, if at all, can such a unity undergo change? There are two basic approaches to this problem present in Newton’s physics. The more familiar grounds unity and change (...) in space and time, the second in the laws of nature. The latter approach is set out in this paper. I argue that a law-constitutive approach to the entities that are the subject-matter of Newton’s physics offers a principle of unity for things, be they simple or composite, and for the parts of composites, such that we also gain an account of what it is for a genuine unity to undergo change in its properties whilst retaining its numerical identity. I end by arguing that the law-constitutive approach favors endurantism over perdurantism. This paper is intended as an example of a particular approach to the relationship between metaphysics and philosophy of physics, according to which, as a philosopher, one engages with physics as a part of the history of philosophy, beginning with our deepest philosophical questions and using the development of physics read as a contribution to natural philosophy to explore how these questions are transformed, re-worked, addressed, and sometimes rendered non-questions.

We propose a new intensional semantics for modal-tense second-order languages with sortal predicates. The semantics provides a variable-domain interpretation of the second-order quantifiers. A formal logical system is characterized and proved to be sound and complete with respect to the semantics. A contemporary variant of conceptualism as a theory of universals is the philosophical background of the semantics. Justification for the variable-domain interpretation of the second-order quantifiers presupposes such a conceptualist framework. | |
In the first part ("Determination"), I consider different notions of determination, contrast and compare modal with non-modal accounts and then defend two a-modality theses concerning essence and supervenience. I argue, first, that essence is a a-modal notion, i.e. not usefully analysed in terms of metaphysical modality, and then, contra Kit Fine, that essential properties can be exemplified contingently. I argue, second, that supervenience is also an a-modal notion, and that it should be analysed in terms of constitution relations between properties. (...) In the second part ("A Theory of Truthmaking"), I first review the literature on ontological commitment, and argue that the notion of truthmaking is better suited to play its explanatory rôle. I then argue that we should take truthmaker theory seriously, and that we should provide actual truthmakers for all truths there are. In the last chapter of this part, I review Armstrong's truthmaker theories and argue that they are unsatisfactory. I generalise my criticism to an argument against truthmaker necessitarianism, the view that truthmakers necessarily make true the truths they are truthmakers of. In the third part ("Properties and their Kind(s)"), I discuss qualitative determination. I present and endorse the truthmaker argument for universals, and defend universalism against friends of tropes, states of affairs and facts. I then give a novel characterisation of the important class of intrinsic properties, building on Lewis' work. With a workable notion of intrinsicness at hand, I argue that relations are ontologically – but not "ideologically" – dispensable: qualitative determination in general is a matter of intrinsic structure. In the future, I plan to add two parts and to publish my thesis as a book: In the fourth part ("Exemplification"), I argue for the existence of an exemplification relation tying universals and particulars together. I derive theoretical benefits from this relation by providing adverbialist theories of modality and tense and identify exemplification with a type of parthood. In the fifth part ("Qua qua qua"), I investigate the curious and interesting ontological category of so-called "qua-objects" (Picasso-as-a-painter, for example) and argue that they exist, are not identical with transworld indidivuals or modal parts and that they provide (contingent) truthmakers for all true predications.

The subjects of this thesis are truth, grounding and dependence. The thesis consists of an introduction and five free-standing essays. The purpose of the introduction is not merely to summarize the papers, but to provide a general background to the discussions in the essays. The introduction is divided into four chapters, each of which splits into a number of sections and/or subsections. Chapter 1. concerns the notion of ontological dependence. I start by making a distinction between two different types of (...) ontological dependence and discuss how well these notions deal with a number of philosophical issues. I then go on to consider the role that ontological dependence plays in hierarchies of natural kinds. In Chapter 2., I discuss a related notion, namely that of grounding. I sketch the theoretical framework by specifying the logical form of grounding statements and a set of structural principles that govern grounding. The chapter ends with a brief discussion on some philosophical applications of grounding. Chapter 3. deals with the notion of truthmaking and how it squares with the grounding framework developed in the previous chapter. I present the reader with the so-called Truthmaker Principle, and provide answers to a number of questions that it raises. The fourth and final chapter summarizes the five papers. The six essays are divided into three categories. Paper I deals with the notion of ontological dependence in hierarchies of natural kinds. Paper II concerns the notion of grounding and resemblance orderings among powers. Papers III, IV and V discuss various aspects of truthmaker theory. (shrink) | |
In contemporary Western culture, death has been widely censured because of its conceptual implications; it lies at the boundaries between reductionism and metaphysics. There is not yet an efficacious epistemology able to solve this contraposition and its consequent collision with science and tradition. This article analyzes Near Death Experiences as a prototypical argument in which the two perspectives conflict. Specifically, it analyzes the epistemological antinomies of the ontological representations of death, inhering in passage versus absolute annihilation. Indeed, the NDEs theme (...) permits the examination of the logical contradiction between monistic reductionism and its ontological counterpart to improve the discovery of a new paradigm that integrates the ecological with eternalist views.
