In the addenda to his Naming and Necessity, Kripke provides an account of how necessary aposteriori statements are possible. In such a case, there is an apriori general principle telling us that it is necessary if true at all. Though straightforward in its broad compass, this account faces two obvious questions in its application: in each case of necessary aposteriori statements, what is the underlying principle and how is it established apriori? I treat these questions with respect to theoretical identity (...) statements concerning chemical substances, such as ‘water is H2OH2O’. I argue that the general principle underlying the necessity of the statements is that if a chemical substance has a certain chemical composition, then it could not have had any other chemical composition. Then I defend the view that the principle is a conceptual truth by providing a novel derivation of it from the theoretical concept of chemical substance with a sufficient level of formal rigor. The logical principles required for the derivation will also be stated and defended. (shrink)

Some philosophers maintain that physical properties are irreducibly modal: that properties are powers. Powers are then employed to provide explanations of other phenomena of philosophical interest such as laws of nature and modality. There is, however, a dispute among powers theorists about how far the powers ontology extends: are all manner of properties at all levels of fundamentality powers or are powers only to be found among the fundamental properties? This paper argues that the answer to this question depends on (...) the details of the metaphysics of powers. More specifically, this paper argues that if one understands powers as qualitative grounds of dispositions, as opposed to properties whose essences are constituted by dispositions, then all properties, be they fundamental or macro, are powers, i.e., pandispositionalism is true. The Conclusion: If qualitative dispositional essentialism is true, then pandispositionalism is true, is significant because there is increasing concern that orthodox dispositional essentialism is explanatorily deficient and perhaps even incoherent, meaning that qualitative dispositional essentialism is gaining increasing support in the literature on powers. All things considered, then, it is beginning to look more likely that pandispositionalism is true simpliciter. (shrink)

I shall discuss some of the relations among metaphysical modality, essence, and explanation. Marion Godman, Antonella Mallozzi and David Papineau have recently argued that the essence of a kind consists in its super-explanatory property—a single property that is causally responsible for a multitude of commonalities shared by the instances of the kind. And they argue that this super-explanatory account of essence offers a principled account of aposteriori necessities concerning kinds. I shall examine their arguments and argue that they are fallacious. (...) Along the way, a general problem will also emerge that applies to any account that tries to explicate the notion of essence in terms of an explanatory relation. (shrink)

Stephen Mumford and Alexander Bird disagree about which properties are powers and, correspondingly, about the extent of the philosophical work to which powers may be put. Unfortunately, there is an important respect in which these authors are talking past each other and so the reason for their disagreement remains obscured. I highlight what has gone wrong in their recent exchange, attempt to clear up the confusion and pinpoint the true source of their disagreement. My hope is to redirect the efforts (...) of these authors and their followers onto more pressing foundational issues in the metaphysics of powers. (shrink)

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. (shrink)

In this paper I investigate the nature of the relation between meaning-interdependence and analyticity. The theory within which meaning-interdependence reaches its peak and becomes omnipresent is meaning holism, according to which every two expressions are meaning-interdependent. A lot of people reject holism partially due to the impression that the theory leads to the picture in which language is self-sufficient in the sense that it is nothing but a game of meanings which is detached from reality. What stands behind that impression (...) is probably something along the lines: analyticity stems from meaning-interdependence, so if all expressions are meaning-interdependent, then everything appears analytic. I defend holism from this kind of objection. I start with showing that analyticity traditionally understood cannot pour over language within holism, because it is not applicable to the theory at all. Then, I argue that adopting some weaker notion of analyticity leads to the ubiquity of analyticity indeed, but analyticity so understood is too weak to actually endanger holism. Finally, I demonstrate that the problems with analyticity appear only when meaning-interdependence is treated in extremely superficial way. I also propose a very simple hierarchy of meaning-interdependence, based on Pagin’s total-pair holism, which immediately repeal the ‘ubiquitous analyticity’ problem. (shrink)

This paper engages critically with Dimitri Gutas’ recent characterization of post-classical Islamic philosophy and theology as a form of paraphilosophy or intellectual activity that merely simulates philosophy. I argue that this view arises from a misguided understanding of the concept of philosophy that should provide the standard for its historiography. In order to avoid a number of problematic consequences, such as gaps in historical continuity or a disconnection from what we understand by philosophy today, we must take our cue from (...) a sufficiently uncontroversial contemporary concept of philosophy instead of any particular historical concept, such as the Peripatetic amalgam of metaphysics, theory of science, and the empirical sciences. Such a strategy provides a sound basis for the inclusion of post-classical thinkers, as well as many classical thinkers who are not falāsifa, in the history of Islamic philosophy without vicious circularity or loss of a normative concept of philosophy.

This paper explores the practice of explanation by status, in which a truth with a certain status is supposed to be explained by its having that status. It first investigates whether such explanations are possible. Having found existing accounts of the practice wanting, it then argues for a novel account of explanation by status as empty-base explanation. The latter notion captures a certain limiting case of ordinary explanation so that according to the empty-base account, explanation by status can be fruitfully (...) understood as a corresponding limiting case of ordinary explanation. One way in which the empty-base account is argued to be superior to other treatments of explanation by status is that it allows for a principled assessment of the possibility of particular kinds of explanation by status. Thus, one result of the present discussion is that explanation by essential status and status as a law are possible, while explanation by merely necessary status is not. (shrink)

In this paper I argue against Armstrong’s recent truthmaking account of possibility. I show that the truthmaking account presupposes modality in a number of different ways, and consequently that it is incapable of underwriting a genuine reduction of modality. I also argue that Armstrong’s account faces serious difficulties irrespective of the question of reduction; in particular, I argue that his Entailment and Possibility Principles are both false.

I defend the intention-dependence of artifacts, which says that something is an artifact of kind K only if it is the successful product of an intention to make an artifact of kind K. I consider objections from two directions. First, that artifacts are often mind- and intention-dependent, but that this isn’t necessary, as shown by swamp cases. I offer various error theories for why someone would have artifact intuitions in such cases. Second, that while artifacts are necessarily mind-dependent, they aren’t (...) necessarily intention-dependent. I consider and reject three kinds of cases which purport to show this: accidental creation, automated production, and mass production. I argue that intentions are present in all of these cases, but not where we would normally expect. (shrink)

Much recent discussion has focused on the nature of artifacts, particularly on whether artifacts have essences. While the general consensus is that artifacts are at least intention-dependent, an equally common view is function essentialism about artifacts, the view that artifacts are essentially functional objects and that membership in an artifact kind is determined by a particular, shared function. This paper argues that function essentialism about artifacts is false. First, the two component conditions of function essentialism are given a clear and (...) precise formulation, after which counterexamples are offered to each. Second, ways to handle the counterexamples suggested by Randall Dipert and Simon Evnine are considered and rejected. Third, I then consider the prospects for restricting function essentialism to so-called technical artifacts, as Lynne Baker does, and argue that this, too, fails. This paper thereby consolidates the scattered literature on function essentialism and shows that, despite the seeming plausibility of the thesis, it should be rejected as an account of artifact essences.

It is widely agreed that the intelligibility of modal metaphysics has been vindicated. Quine's arguments to the contrary supposedly confused analyticity with metaphysical necessity, and rigid with non-rigid designators.2 But even if modal metaphysics is intelligible, it could be misconceived. It could be that metaphysical necessity is not absolute necessity – the strictest real notion of necessity – and that no proposition of traditional metaphysical interest is necessary in every real sense. If there were nothing otherwise “uniquely metaphysically significant” about (...) metaphysical necessity, then paradigmatic metaphysical necessities would be necessary in one sense of “necessary”, not necessary in another, and that would be it. The question of whether they were necessary simpliciter would be like the question of whether the Parallel Postulate is true simpliciter – understood as a pure mathematical conjecture, rather than as a hypothesis about physical spacetime. In a sense, the latter question has no objective answer. In this article, I argue that paradigmatic questions of modal metaphysics are like the Parallel Postulate question. I then discuss the deflationary ramifications of this argument. I conclude with an alternative conception of the space of possibility. According to this conception, there is no objective boundary between possibility and impossibility. Along the way, I sketch an analogy between modal metaphysics and set theory. (shrink)

Aim of the paper is to present a new logic of technical malfunction. The need for this logic is motivated by a simple-sounding philosophical question: Is a malfunctioning corkscrew, which fails to uncork bottles, nonetheless a corkscrew? Or in general terms, is a malfunctioning F, which fails to do what Fs do, nonetheless an F? We argue that ‘malfunctioning’ denotes the modifier Malfunctioning rather than a property, and that the answer depends on whether Malfunctioning is subsective or privative. If subsective, (...) a malfunctioning F is an F; if privative, a malfunctioning F is not an F. An intensional logic is required to raise and answer the question, because modifiers operate directly on properties and not on sets or individuals. This new logic provides the formal tools to reason about technical malfunction by means of a logical analysis of the sentence “a is a malfunctioning F”. (shrink)

The notions of ground and ontological dependence have made a prominent resurgence in much of contemporary metaphysics. However, objections have been raised. On the one hand, objections have been raised to the need for distinctively metaphysical notions of ground and ontological dependence. On the other, objections have been raised to the usefulness of adding ground and ontological dependence to the existing store of other metaphysical notions. Even the logical properties of ground and ontological dependence are under debate. In this article, (...) I focus on how to account for the judgements of non-symmetry in several of the cases that motivate the introduction of notions like ground and ontological dependence. By focusing on the notion of explanation relative to a theory, I conclude that we do not need to postulate a distinctively asymmetric metaphysical notion in order to account for these judgements.

Traditionally, nature has often been thought to be structured by essential forms providing the generic features of natural things and thus the foundations for scientific explanations. In contrast, human history and the social domain have been thought to be the realm of ever-changing appearances, where contingency prevails. The paper argues that the existence of essential forms is compatible with the contingent, mind-dependent and historical character of the social world, and that essential forms can also be found in the social domain. (...) Two categories of entities are discussed that suggest themselves to be identified as social forms, namely social kinds and social identities. To this end, it is shown that standard arguments for the existence of essential forms also apply to the social domain, and objections to the existence of social forms are rebutted. Particular attention is paid to the explanatory appeal of social forms. The paper concludes by suggesting that, far from being oppressive, essential social forms are presupposed by liberating social practices. (shrink)

I know that I could have been where you are right now and that you could have been where I am right now, but that neither of us could have been turnips or natural numbers. This knowledge of metaphysical modality stands in need of explanation. I will offer an account based on our knowledge of the natures, or essencess, of things. I will argue that essences need not be viewed as metaphysically bizarre entities; that we can conceptualise and refer to (...) essences; and that we can gain knowledge of them. We can know about which properties are, and which properties are not, essential to a given entity. This knowledge of essence offers a route to knowledge of the ways those entities must be or could be. (shrink)

Essentialists understand modal properties in terms of the essences of things. Given this view, it is natural to think that our knowledge of modality ultimately derives from our knowledge of the essences of things. Is that view plausible? Do we genuinely have knowledge of the essences of things, in a form substantial enough to ground our modal knowledge? The more we pack into the notion of essence to allow it to underpin modal properties, the harder it is to claim genuine (...) knowledge. I will argue that realists about essence of a certain kind can have the best of both worlds. They can co-opt a conventionalist explanation of our knowledge of essence, but against the background of a fully realist notion of essence. (shrink)

Bundle theories identify material objects with bundles of properties. On the traditional approach, these are the properties possessed by that material object. That view faces a deep problem: it seems to say that all of an object’s properties are essential to it. Essential bundle theory attempts to overcome this objection, by taking the bundle as a specification of the object’s essential properties only. In this paper, I show that essential bundle theory faces a variant of the objection. To avoid the (...) problem, the theory must accept the contingency of identity. I show how this can be achieved in a coherent and well-motivated way, a way that isn’t available to traditional bundle theories. (shrink)

Propositions play a central role in contemporary semantics. On the Russellian account, propositions are structured entities containing particulars, properties and relations. This contrasts sharply with the sets-of-possible-worlds view of propositions. I’ll discuss how to extend the sets-of-worlds view to accommodate fine-grained hyperintensional contents. When this is done in a satisfactory way, I’ll argue, it makes heavy use of entities very much like Russellian tuples. The two notions of proposition become inter-definable and inter-substitutable: they are not genuinely distinct accounts of how (...) propositions represent what they represent. Semantic theorists may move freely between the two conceptions of what propositions are. Nevertheless, the two approaches give different accounts of the metaphysical nature of propositions. I argue that the sets-of-worlds view provides an adequate account of the nature of propositions, whereas the Russellian view cannot. (shrink)

Possible worlds, concrete or abstract as you like, are irrelevant to the truthmakers for modality—or so I shall argue in this paper. First, I present the neo-Humean picture of modality, and explain why those who accept it deny a common sense view of modality. Second, I present what I take to be the most pressing objection to the neo-Humean account, one that, I argue, applies equally well to any theory that grounds modality in possible worlds. Third, I present an alternative, (...) properties-based theory of modality and explore several specific ways to flesh the general proposal out, including my favored version, the powers theory. And, fourth, I offer a powers semantics for counterfactuals that each version of the properties-based theory of modality can accept, mutatis mutandis. Together with a definition of possibility and necessity in terms of counterfactuals, the powers semantics of counterfactuals generates a semantics for modality that appeals to causal powers and not possible worlds.

How could perceptual experiences reveal matters of essentiality? Answering this question is crucial for vindicating a thesis about the epistemic import of experience, commonly known as Revelation. The thesis comes in a weak and a strong version. Only on the strong one could it make up an authoritative piece of common sense. But this version also seems to demand too much of our experiences, namely that they can reveal essentiality. However, the impression that our experiences are not suited for this (...) turns out to be due to a non-mandatory assumption about how the revelation of essentiality would work. (shrink)

Quantum mechanics seems to portray nature as nonseparable, in the sense that it allows spatiotemporally separated entities to have states that cannot be fully specified without reference to each other. This is often said to implicate some form of “holism.” We aim to clarify what this means, and why this seems plausible. Our core idea is that the best explanation for nonseparability is a “common ground” explanation, which casts nonseparable entities in a holistic light, as scattered reflections of a more (...) unified underlying reality.

One notable area in analytic metaphysics that has seen a revival of Aristotelian and scho- lastic inspired metaphysics is the return to a more robust construal of the notion of essence, what some have labelled “real” or “serious” essentialism. However, it is only recently that this more robust notion of essence has been implemented into the debate on truthmaking, mainly by the work of E. J. Lowe. The first part of the paper sets out to explore the scholastic roots of (...) essential dependence as well as an account of truthmaking for accidental predications in terms of accidents. Along the way, the author examines the dialectical role the possibility of separated accidents in the Eucharist play with respect to developing a scholastic account of truthmaking as essential dependence. In conclusion the author utilises Aquinas’s hylomorphic ontology to suggest a new way forward for an essentialist account of truthmaking. (shrink)

Presentists believe that only present things exist. But opponents insist this view has unacceptable implications: if only present things exist, we can’t express singular propositions about the past, since the obvious propositional constituents don’t exist, nor can we account for temporal passage, or the openness of the future. According to such opponents, and in spite of the apparent ‘common sense’ status of the view, presentism should be rejected on the basis of these unacceptable implications. In this paper, I present and (...) defend a version of presentism that avoids the unacceptable implications. The basic strategy I employ is familiar—I postulate presently existing entities to serve as surrogates for non-present entities—but some of the details of my proposal are more novel, and their application to these problems is certainly novel. One overarching thesis of this paper is that Thisness Presentism is preferable to other versions of presentism since it solves important problems facing standard iterations of the view. And I assume that this is a good positive reason in favour of the underlying thisness ontology. (shrink)

According to the iterative conception of set, sets can be arranged in a cumulative hierarchy divided into levels. But why should we think this to be the case? The standard answer in the philosophical literature is that sets are somehow constituted by their members. In the first part of the paper, I present a number of problems for this answer, paying special attention to the view that sets are metaphysically dependent upon their members. In the second part of the paper, (...) I outline a different approach, which circumvents these problems by dispensing with the priority or dependence relation altogether. Along the way, I show how this approach enables the mathematical structuralist to defuse an objection recently raised against her view. (shrink)

The current interest in the notions of ontological dependence and metaphysical grounding is usually associated with a renewal of interest in Aristotelian metaphysics. Curiously, some authors have recently argued that the Aristotelian view of universals, according to which universals depend for their existence on their exemplifiers, is incoherent from a grounding perspective. In this paper I argue that such criticism is misleading. I shall examine their arguments and clarify the supposed incoherence.

The normative notion of fittingness figures saliently in the work of a number of ethical theorists writing in the late nineteenth and mid-twentieth centuries and has in recent years regained prominence, occupying an important place in the theoretical tool kits of a range of contemporary writers. Yet the notion remains strikingly undertheorized. This article offers a (partial) remedy. I proceed by canvassing a number of attempts to analyze the fittingness relation in other terms, arguing that none is fully adequate. In (...) explaining why various analyses of fittingness fail, I draw into relief certain of the relation’s constitutive features and spotlight some of its interesting and important connections to various other properties. Along the way, I highlight the relation’s relevance to a number of ongoing debates in normative and metanormative philosophy. I conclude by indicating some directions for further research. (shrink)

Philosophical analysis was the central preoccupation of 20th-century analytic philosophy. In the contemporary methodological debate, however, it faces a number of pressing external and internal challenges. While external challenges, like those from experimental philosophy or semantic externalism, have been extensively discussed, internal challenges to philosophical analysis have received much less attention. One especially vexing internal challenge is that the success conditions of philosophical analysis are deeply unclear. According to the standard textbook view, a philosophical analysis aims at a strict biconditional (...) that captures the necessary and sufficient conditions for membership in the relevant category. The textbook view arguably identifies a necessary condition on successful philosophical analyses, but understood as a sufficient condition it is untenable, as I will argue in this paper. To this end, I first uncover eight conditions of adequacy on successful philosophical analyses, some of which have rarely been spelled out in detail. As we shall see, even sophisticated alternatives to the textbook view fail to accommodate some of these conditions. I then propose the concept grounding view as a more promising account of philosophical analysis. According to this view, successful philosophical analyses require necessary biconditionals that are constrained by grounding relations among the concepts involved. Apart from providing a satisfactory account of philosophical analysis in its own right, the concept grounding view is also able to meet the challenge that the success conditions of philosophical analysis are problematically unclear. (shrink)

In recent work, E. J. Lowe presents an essence-based account of our knowledge of metaphysical modality that he claims to be superior to its main competitors. I argue that knowledge of essences alone, without knowledge of a suitable bridge principle, is insufficient for knowing that something is metaphysically necessary or metaphysically possible. Yet given Lowe's other theoretical commitments, he cannot account for our knowledge of the needed bridge principle, and so his essence-based modal epistemology remains incomplete. In addition to that, (...) Lowe's account implies a psychologically unrealistic reconstruction of how we ordinarily acquire knowledge of metaphysical modalities. The discussion of Lowe's suggestive essence-based account is also intended as a case study that illustrates a more general problem in the epistemology of modality: the great difficulty of explaining our modal knowledge in terms of a single overtly nonmodal kind of knowledge. The failure of Lowe's account suggests that such a sweeping reductive explanation of our modal knowledge might simply not be available. This should be good news for those philosophers who champion less reductive or more pluralistic accounts of our modal knowledge. (shrink)

Most contemporary action theorists deny the possible existence of intentionally evil actions or diabolic agency. The reason for this is a normative interpretation of agency that appears to be motivated by action theoretic concerns, where agents are conceived as necessarily acting sub specie bonie or under ‘the guise of the good’. I argue that there is nothing in human agency to motivate this view and that diabolic evil is not at odds with inherent features of our nature.

Hugh Mellor has proposed what appears to be a new solution to the problem of intrinsic change (Mellor 1998). Assuming endurantism and a B‐theoretic, nonpresentist view of time, facts are supposed to have only enduring things and atemporal properties (or relations) as constituents, but no times. The having of properties and relations is not relativised to times. Instead, the whole of a fact is conceived of as temporally localised. It will be argued that this interesting and novel proposal does not (...) succeed as an account of change in the intrinsic properties of things. The basic difficulty is that the view still leads into contradiction, since it makes it incomprehensible how one and the same thing can have both a property and some incompatible property. The having of these incompatible properties is treated as two facts. But to add that these facts have certain temporal locations is of no help for avoiding the contradiction. (shrink)

Let an X/Y distinction be a distinction between kinds of properties, such as the distinctions between qualitative and non-qualitative, intrinsic and extrinsic, perfectly natural and less-than-perfectly natural or dispositional and categorical properties. An X/Y distinction is hyperintensional iff there are cointensional properties P and Q, such that P is an X-property, whereas Q is a Y-property. Many accounts of metaphysical distinctions among properties presuppose that such distinctions are non-hyperintensional. In this paper, I call this presupposition into question. I develop a (...) sufficient condition for the hyperintensionality of X/Y distinctions and argue that this condition is satisfied by a number of standard classifications of properties. It follows that non-hyperintensional analyses of distinctions among properties are harder to defend than is often assumed. (shrink)

An important task for metaphysicians and philosophers of science is to account for laws of nature – in particular, how they distinguish themselves from ‘mere’ regularities, and the modal force they are endowed with, ‘natural necessity’. Dispositional essentialism about laws is roughly the view that laws distinguish themselves by being grounded in the essences of natural entities. This paper does not primarily concern how essentialism compares to its main rivals – Humeanism and Armstrongeanism. Rather, it distinguishes and comparatively assesses various (...) brands of essentialism – which mainly differ as to where exactly they take laws to find their essentialist sources, and what they take to be the targets of laws, namely what they apply to. Yet, this internal comparison is not unrelated to the more general debate about laws: the main criteria with which I compare these essentialist views concern how they can deal with some of the main objections faced by essentialism in general, and how they can keep what is arguably the main intuitive advantage of essentialism over its rivals. Thus, the paper also concerns the relative position of essentialism in the larger debate about laws – ultimately bringing support to it. (shrink)

A common feature of all standard theories of the laws of nature is that they are "absolutist": They take laws to be either all metaphysically necessary or all contingent. Science, however, gives us reason to think that there are laws of both kinds, suggesting that standard theories should make way for "non-absolutist" alternatives: theories which accommodate laws of both modal statuses. In this paper, we set out three explanatory challenges for any candidate non-absolutist theory and discuss the prospects of the (...) two extant candidates in light of these challenges. We then develop our own non-absolutist theory, the essentialist DTA account, which combines the nomic-necessitation or DTA account with an essentialist approach to metaphysical modality in order to meet the three explanatory challenges. Finally, we argue that the distinction between kinematical and dynamical laws found in physical theories supports both non-absolutism in general and our proposed essentialist DTA view in particular. (shrink)

In a recent paper, Tuomas Tahko has argued for a hybrid view of the laws of nature, according to which some physical laws are metaphysically necessary, while others are metaphysically contingent. In this paper, we show that his criterion for distinguishing between these two kinds of laws — which crucially relies on the essences of natural kinds — is on its own unsatisfactory. We then propose an alternative way of drawing the metaphysically necessary/contingent distinction for laws of physics based on (...) the central kinematical/dynamical distinction used in physical theorising, and argue that the criterion can be used to amend Tahko’s own account, but also that it can be combined with different metaphysical views about the source of necessity.

It is widely accepted that necessity comes in different varieties, often called ‘kinds': metaphysical necessity, logical necessity, natural necessity, conceptual necessity, moral necessity, to name but a few – and the same goes for the varieties of possibility. What is usually not fully appreciated, however, is that modal variety is not simply ‘unidimensional': it does not only involve one main variable – kind, whose values are the particular kinds of necessity. Rather, I argue, it is ‘bidimensional', involving two distinct variables (...) – domain and strength. In the first part of the paper, I introduce and develop the proposed bidimensional picture of modal variety, defending it against the common, unidimensional one. In the second part, I consider how the main available accounts of necessities and their relations rely, at least to a significant extent, on the latter picture, pointing out important limitations that they face as a result. I also show how, accordingly, alternative accounts based on a clear and systematic distinction between domain and strength would overcome those limitations. I conclude that, beyond the particular bidimensionalist view defended, our understanding of the modal realm may benefit from more direct debate on whether and how it is multidimensional. (shrink)

There has been much work on ontological dependence in recent literature. However, relatively little of it has been dedicated to the ways in which individual physical objects may depend on other distinct, non-overlapping objects. This paper gives several examples of such object-dependence and distinguishes between different types of it. The paper also introduces and refines the notion of an n-tet. N-tets (typically) occur when there are object-dependence relations between n objects. I claim that the identity (or, rather, what I call (...) the n-dentity) conditions for n-tets are not grounded in the individual identity conditions of each of the n objects, but instead are metaphysically basic. The paper then briefly discusses some ramifications of accepting object-dependence (and n-tets) on the philosophy of biology, ethics, and logic. (shrink)

There is a widely extended viewpoint about physical possibility, what we will call Standard Approach, which holds that the physically possible is delimited by the nomological structure of physical theories: to be physically possible is to be in accordance with the physical laws, to be physically impossible is to be prohibited by physical laws and to be physically necessary is to be demanded by the physical laws. However, it is possible to show that this approach is too relaxed and permissive (...) when it comes to collecting and systematizing many of the modal intuitions present in the physical community. In this work we will argue, on the one hand, that the notion of physical possibility is more complex and richer than suggested by the standard approach and, on the other hand, that it is necessary to add some extra elements to the characterization of physical possibility in order to that it is adequate in scientific contexts.

In an influential passage of Naming and Necessity Kripke argues, with the help of a fictional dialogue, that de re metaphysical modal distinctions have intuitive content. In this note I clarify the workings of the argument, and what it does and does not support. I conclude that Kripke’s argument does not, despite possible appearances, support the view that metaphysical modal distinctions are made in common sense discourse. The argument does however support the view that if metaphysical modal distinctions make sense (...) at the level of statements or states of affairs, then they also make sense de re. (shrink)

There is a line of thought, neglected in recent philosophy, according to which a priori knowable truths such as those of logic and mathematics have their special epistemic status in virtue of a certain tight connection between their meaning and their truth. Historical associations notwithstanding, this view does not mandate any kind of problematic deflationism about meaning, modality or essence. On the contrary, we should be upfront about it being a highly debatable metaphysical idea, while nonetheless insisting that it be (...) given due consideration. From this standpoint, I suggest that the Finean distinction between essence and modality allows us to refine the view. While liberal about meaning, modality and essence, the view is not without bite: it is reasonable to suppose that it is able to ward off philosophical confusions stemming from the undue assimilation of a priori to empirical knowledge.

It has been argued by Bernard Linsky and Edward Zalta, and independently by Timothy Williamson, that the best quantified modal logic is one that validates both the Barcan Formula and its converse. This requires that domains be fixed across all possible worlds. All objects exist necessarily; some – those we would usually consider contingent – are concrete at some worlds and non-concrete (but still existent) at others. Linsky and Zalta refer to such objects as ‘contingently non-concrete’. I defend the standard (...) usage of the word ‘exists’, and the view that many objects exist only contingently. I argue that the Linsky/Zalta analysis, and to a lesser extent Williamson’s, suffers not only from a peculiar ontology but also from two related formal difficulties. Their analysis gives either counter-intuitive or ad hoc results about essences, and it fails to accommodate contingently existing abstracta. (shrink)
