The traditional ontology within which chemistry has developed involved various versions of a general substance/attribute scheme. Recently this has been challenged by two versions of Dynamism. One version is derived from the writings of A. N. Whitehead and the other from several sources, including G. Leibniz and I. Kant. Both involve the idea of flux of actual occasions. Unlike the former scheme, the latter involves a foundation of causal powers and the energetics of field theory. The situation has been made (...) more interesting because of the revival of trope theory, based on an ontology of particularized attributes. This notion is claimed to resolve philosophical problems about the nature of universals and of substances through the introduction of spatial and temporal sequences of tropes. While trope theory seems, at first sight, to work as an attractive alternative to substance/attribute close inspection shows that it is beset with difficulties that are more problematic that the dynamist ontology based on casual powers, dispositions and affordances.

Three arguments for the conclusion that objects cannot endure in B-time even if they remain intrinsically unchanged are examined: Carter and Hestevolds enduring-objects-as-universals argument (American Philosophical Quarterly 31(4):269-283, 1994) and Barker and Dowe's paradox 1 and paradox 2 (Analysis 63(2):106-114, 2003, Analysis 65(1):69-74, 2005). All three are shown to fail.

Many powers metaphysicians postulate both active and passive powers, understood as distinct kinds of intrinsic causal properties of objects. I argue that the category of passive power is superfluous. I also offer a diagnosis of how philosophers are misled to postulate passive powers.

Can the physicalist consistently hold that representational content is all there is to sensory experience and yet that two perceivers could have inverted phenomenal spectra? Yes, if he holds that the phenomenal properties the inverts experience are dummy properties, not instantiated in the physical objects being perceived nor in the perceivers.

In this paper, I argue that Hume's solution to a problem that contemporary metaphysicians call “the problem of universals” would be rather trope-theoretical than some other type of nominalism. The basic idea in different trope theories is that particular properties, i.e., tropes are postulated to account for the fact that there are particular beings resembling each other. I show that Hume's simple sensible perceptions are tropes: simple qualities. Accordingly, their similarities are explained by these tropes themselves and their resemblance. Reading (...) Hume as a trope nominalist sheds light on his account of general ideas, perceptions, relations and nominalism. (shrink)

I argue that relations between non-collocated spatial entities, between non-identical topological spaces, and between non-identical basic building blocks of space, do not exist. If any spatially located entities are not at the same spatial location, or if any topological spaces or basic building blocks of space are non-identical, I will argue that there are no relations between or among them. The arguments I present are arguments that I have not seen in the literature.

I argue that relations between non-identical times, such as the relations, earlier than, later than, or 10 seconds apart, involve contradiction, and only co-temporal relations are non-contradictory, which would leave presentism the only non-contradictory theory of time. The arguments I present are arguments that I have not seen in the literature.

I discuss the relations between God and spatial entities, such as the universe. An example of a relation between God and a spatial entity is the relation,causes. Such relations are, in D.M. Armstrong’s words, ‘realm crossing’ relations: relations between or among spatial entities and entities in the realm of the spatially unlocated. I discuss an apparent problem with such realm crossing relations. If this problem is serious enough, as I will argue it is, it implies that God cannot be the (...) creator of the universe I also discuss that if God cannot be the creator of the universe, then God does not exist.

According to non-reductive physicalism, mental properties of the phenomenal sort are essentially different from physical properties, and cannot be reduced to them. This being a quarrel about properties, I draw on the categorical / dispositional distinction to discuss this non-reductive claim. Typically, non-reductionism entails a categorical view of phenomenal properties. Contrary to this, I will argue that phenomenal properties, usually characterized by what it is like to have them, are mainly the manifestation of dispositional properties. This paper is thus divided (...) into two parts. In the first part, after tracing a working distinction between categorical and dispositional properties, I argue that there is a form of incoherence looming behind the idea of taking phenomenal properties as categorical. In the second part, I argue in favor of the view that phenomenal properties are dispositional properties with an essential manifestation. This interpretation allows us to broaden dispositionalism so as to include the sciences of mind, thus ultimately favoring a physicalist view on the mind. (shrink)

Many philosophers and scientists believe that we need an explanation as to why the laws of physics and the initial conditions of the universe are fine-tuned for life. The standard two options are: theism and the multiverse hypothesis. Both of these theories are extravagant and arguably have false predictions. Drawing on contemporary philosophy of mind, I outline a form of panpsychism that I believe offers a more parsimonious and less problematic explanation of cosmological fine-tuning.

An electron clearly has the property of having a charge of þ1.6 10 19 coulombs, but does it also have the property of being charged ? Philosophers have worried whether so-called ‘determinable’ predicates, such as ‘is charged’, actually refer to determinable properties in the way they are happy to say that determinate predicates, such as ‘has a charge of þ1.6 10 19 coulombs’, refer to determinate properties. The distinction between determinates and determinables is itself fairly new, dating only to its (...) definition by the Cambridge logician W. E. Johnson early in the last century.1 But despite its newly minted condition the distinction has found little currency in on-going philosophical debates. Or at least until recently. Renewed interest in realist positions about properties, and arguments that the determinable-determinate relation may hold the key to understanding mental causation, have thrust Johnson’s distinction to the fore. With this new attention has also come new ‘optimistic’ positions that endorse the existence of determinable properties. David Armstrong, Evan Fales, and Sydney Shoemaker, among others, have all defended such optimistic accounts that take determinable predicates, such as ‘is charged’, to refer to determinable properties.2 In this paper, our goal is to carefully assess optimism and to argue that a pessimistic view, which rejects the existence of determinable properties, is actually the appropriate default position.

Given Kim’s principle of explanatory exclusion (EE), it follows that in addition to the problem of mental causation, dualism faces a problem of mental explanation. However, the plausibility of EE rests upon the acceptance of a further principle concerning the individuation of explanation (EI). The two methods of defending EI—either by combining an internal account of the individuation of explanation with a semantical account of properties or by accepting an external account of the individuation of explanation—are both metaphysically implausible. This (...) is not, however, to reject the problem of mental explanation, for EE can be replaced with a far weaker principle, which does not require the acceptance of EI, but which generates a similar problem for dualism.

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)

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)

I examine different strategies involved in stating anti-theistic arguments from natural evil, and consider some theistic replies. There are, traditionally, two main types of arguments from natural evil: those that purport to deduce a contradiction between the existence of natural evil and the existence of God, and those that claim that the existence of certain types or quantities of natural evil significantly lowers the probability that theism is true. After considering peripheral replies, I state four prominent theistic rebutting strategies: skeptical (...) theism; Richard Swinburne's view that moral knowledge entails natural evil; the soul-making theodicy; and the natural law theodicy.

Tropes, as distinguished from other possible kinds of entities such as universals, states of affairs, events and bare particulars, are best-suited to play the role of causal relata.

The absence of a necessary connection in singular causation is a key step in the Humean argument against any form of necessity in causation. I argue that Hume's defence of this step is unsuccessful, and that the step could be skipped, accepting the possibility of necessary a posteriori truths. Still this does not suffice to guarantee a necessary connection in singular causation. Necessary a posteriori truths should be backed by necessary a priori truths. Thus, a main object of this paper (...) is to argue that an a priori philosophical concept of causality involves a necessary connection between its terms. (shrink)

While the concept of multiple realizability is widely used, it is seldom rigorously characterized. This paper defends a liberal conception of multiple realizability as sameness of type through _any_ differences in the (lower-level) conditions that give rise to instances of that type. This kind of “sameness through difference” is contrasted with another type of asymmetric dependency relation between properties, multiple _specification_. This liberal conception is then defended from objections, and it is augmented by a concept of relativized multiple realizability. The (...) last section presents a survey of the ontological, explanatory, and methodological consequences of this analysis of multiple realizability. (shrink)

The ubiquitous schema ‘All Fs are Gs’ dominates much philosophical discussion on laws but rarely is it shown how actual laws mentioned and used in science are supposed to fit it. After consideration of a variety of laws, including those obviously conditional and those superficially not conditional, I argue that we have good reason to support the traditional interpretation of laws as conditionals of some quantified form with a single object variable. I show how this conclusion impacts on the status (...) of ‘system laws’ and the significance of having only one object variable with regard to the relationship between laws and causal relations.

The question of whether or not to partition data for the purposes of inferring phylogenetic hypotheses remains controversial. Opinions have been especially divided since Kluge's (1989, Systematic Zoology 38, 7–25) claim that data partitioning violates the requirement of total evidence (RTE). Unfortunately, advocacy for or against the RTE has not been based on accurate portrayals of the requirement. The RTE is a basic maxim for non-deductive inference, stipulating that evidence must be considered if it has relevance to an inference. Evidence (...) is relevant if it has a positive or negative effect on a given conclusion. In the case of ℈partitioned’ phylogenetic inferences, the RTE is violated, and the basis for rational belief in any conclusion is compromised, unless it is shown that the partitions are evidentially irrelevant to one another. The goal of phylogenetic systematics is to hypothesize past causal conditions to account for observed shared similarities among two or more species. Such inferences are non-deductive, necessitating consideration of the RTE. Some phylogeneticists claim the parsimony criterion as justification for the RTE. There is no relation between the two – parsimony is a relation between a hypothesis and causal question(s). Parsimony does not dictate the content of premises prior to an inference. ℈Taxonomic congruence,’ ℈supertrees,’ and ℈conditional combination’ methods violate the RTE. Taxonomic congruence and supertree methods also fail to achieve the intended goal of phylogenetic inference, such that ℈consensus trees’ and ℈supertrees’ lack an empirical basis. ℈Conditional combination’ is problematic because hypotheses derived from partitioned data cannot be compared – a causal hypothesis inferred to account for a set of effects only has relevance to those effects, not any comparative relevance to other causal hypotheses. A similar problem arises in the comparisons of hypotheses derived from different causal theories. (shrink)

Structural universals are a kind of complex universal. They have been put to work in a variety of philosophical theories but are plagued with problems concerning their compositional nature. In this article, we will discuss the following questions. What are structural universals? Why believe in them? Can we give a consistent account of their compositional nature? What are the costs of doing so?

I apply the notion of truthmaking to the topic of fundamentality by articulating a truthmaker theory of fundamentality according to which some truths are truth-grounded in certain entities while the ones that don't stand in a metaphysical-semantic relation to the truths that do. I motivate this view by critically discussing two problems with Ross Cameron's truthmaker theory of fundamentality. I then defend this view against Theodore Sider's objection that the truthmaking approach to fundamentality violates the purity constraint. Truthmaker theorists can (...) have a trouble-free theory of fundamentality. (shrink)

The concept of instantiation is realized differently across a variety of metaphysical theories. A certain realization of the concept in a given theory depends on what roles are specified and associated with the concept and its corresponding term as well as what entities are suited to fill those roles. In this paper, the classic realization of the concept of instantiation in a one-category ontology of abstract particulars or tropes is articulated in a novel way and defended against unaddressed objections.

The so-called Mind argument aims at the conclusion that agents act freely only if determinism is true. The soundness of this argument entails the falsity of libertarianism, the two-part thesis that agents act freely, and free action and determinism are incompatible. In this paper, I offer a new formulation of the Mind argument. I argue that it is true by definition that if an agent acts freely, either (i) nothing nomologically grounds an agent’s acting freely, or (ii) the consequence argument (...) for incompatibilism is unsound. I define the notion of nomological grounding, and argue that unless an agent’s acting freely is nomologically grounded, unacceptable consequences follow. I then argue that if agents act freely and the consequence argument is sound, a vicious regress ensues. I conclude by considering the libertarian’s dialectical options. (shrink)

Mereology, the theory of parts and wholes, is sometimes used as a framework for categorisation because it is regarded as ontologically innocent in the sense that the mereological fusion of some entities is nothing over and above the entities. In this paper it is argued that an adequate answer to the question of whether the thesis of the ontological innocence of mereology holds relies crucially on the underlying theory of reference. It is then shown that upholding the thesis comes at (...) high costs, viz. at the cost of a quite strong logical background theory or at paradoxical ways of predicating and counting. (shrink)

This paper elaborates the problem of temporal unity for dynamic presentism and diagnoses the source of that problem in the dynamic presentist’s discarding the traditional C-series in its avoidance of McTaggart’s A-series paradox. This C-series provided the fixed structure of time which the transitory aspects of time then followed, and thereby unify those transitory aspects. It then considers ersatzer presentism as an ostensible solution to the problem of temporal unity by providing a new abstract C-series for dynamic presentism. However, after (...) a closer examination of the details of this proposal, it is found that the ersatz-B-series itself needs to be temporally variable to capture the transitory aspects of time that it is meant to track. Consequently, it cannot provide the fixed structure of time required to unify the transitory aspects of time into a temporal series. It is therefore suggested that dynamic presentists look for a more course-grained determiner of temporal progression to construct the presentist-friendly C-series required to unify their transitory aspects of time.

This essay outlines an explanatory virtue of presentism: its unique ability amongst temporal metaphysics to deliver a partial explanation of the conservational character of natural laws. That explanation relies on presentism, uniquely amongst temporal metaphysics, being able to support an endurantist account of persistence. In particular, after reconsidering a former argument for endurantism entailing presentism by Merricks, a new argument for this entailment, is expounded. Before delivering the explanation of the conservational character of natural laws, a brief account of that (...) explanandum is given, followed by an elaboration of the wider significance of an explanation for the conservational character for natural laws, particularly for the dispositional essentialist project of nomic reductionism, and explaining the non-simultaneity of causation.

The identity theory of truth, according to which true thoughts are identical with facts, is very hard to formulate. It oscillates between substantive versions, which are implausible, and a merely truistic version, which is difficult to distinguish from deflationism about truth. This tension is present in the form of identity theory that one can attribute to McDowell from his views on perception, and in the conception defended by Hornsby under that name.

To be a realist about modality, need one claim that more exists than just the various objects and properties that populate the world—e.g. worlds other than the actual one, or maximal consistent sets of propositions? Or does the existence of objects and properties by itself involve the obtaining of necessities (and possibilities) in re? The latter position is now unpopular but not unfamiliar. Aristotle held that objects have essences, and hence necessarily have certain properties. Recently it has been argued that (...) the identity of any property is tied to the natural laws in which it figures, which entails that the occurrence of properties involves the obtaining of nomological necessities ([24], pp. 206-33 and 234-60; [23]; cf. [25] and [6]). Somewhat less recently, Wittgenstein ([28], p. 168) worried that the reality of at least some properties—precise shades of colors being a prime example—involved the obtaining in re of certain impossibilities. This paper argues that Wittgenstein’s worries were right, and not just concerning some properties, but all properties whatever. That there are objects and properties in the world at all, then, amounts to there obtaining modal states of affairs. This argument supplements, rather than replaces, the others. The position on property incompatibility advanced here actually helps defend Aristotelian essentialism against epistemological objections, or so I have argued ([15]). And while this paper’s position on property incompatibility diverges from the idea that a property’s nomic profile is essential to it—more on this in the next section—it is at least compatible with the thought that the necessity involved in the laws of nature enters into ontology at the ground level.

An influential line of thought in metaphysics holds that where common sense discerns a tree or a dog or a baseball there may be just many microparticles. Provided the microparticles are arranged in the right way -- are “treewise” or “dogwise” or “baseballwise” arranged -- our sensory experiences will be just the same as if a tree or dog or baseball were really there. Therefore whether there really are suchfamiliar objects in the world can be decided only by determining what (...) more is needed for microparticles dogwise arranged actually to compose a dog. This paper argues that this line of thought sets up the wrong agenda. Composition is trivial; dogwise (etc.) arrangement is tricky. Dogwise arrangement will obtain in the wrong regions unless we stipulate that there are dogs, and that dogwise arrangementobtains only within their borders. The bearers of dogwise arrangement, moreover, will have to be dogs themselves, not their microparticles. Thus allowing that dogwise arrangement obtains at all is allowing that there are dogs.

A mutation alters the hemoglobin in some members of a species of antelope, and as a result the members fare better at high altitudes than their conspecifics do; so high-altitude foraging areas become open to them that are closed to their conspecifics; they thrive, reproduce at a greater rate, and the gene for altered hemoglobin spreads further through the gene pool of the species. That sounds like a classic example (owed to Karen Neander, 1995) of a causal chain traced by (...) evolutionary biology. But a view now nearly universal among philosophers maintains that such biological causation is always shadowed, perhaps even rivaled, by causation on a different level.1 That the subgroup of antelopes forages in areas closed to the conspecifics is a state of affairs embodied or realized, notes this view, in certain movements and state changes done by certain physical microparticles—untold billions of microparticles and movements, but a finite and determinate (more on this below) collection nevertheless. That the subgroup reproduces at a greater rate is likewise realized by a huge collection of microparticle movements, a different collection. And the microparticle happenings comprised in the first collection are causally responsible, strictly in accordance with the laws of microphysics, for the microparticle happenings in the second. Biological causation is always shadowed, perhaps even rivaled, by causation on the level of microphysics. The view I mean is general: any case of causing uncovered by any of the special sciences can be recaptured at the level of microphysics. This view is I think what most philosophers mean by “physicalism”; in any case, “physicalism” is the label I shall use. Physicalism comes in two forms. Modest physicalism holds that any causal transaction reported by the special sciences can be retraced by microphysics.2 Hegemonic physicalism holds that retracing such a transaction at the level of..

The debate between relational versus constituent substance ontology is longstanding and ongoing. In the contemporary literature it is mostly taken for granted that any version of hylomorphism must count as a constituent substance ontology. Here I argue that a certain sort of relational substance ontology could also legitimately be labeled hylomorphic, and in fact that relational substance ontologists have some good reasons to affirm this version of hylomorphism.

In this paper, I focus on life-threatening medical conditions and argue that from the point of view of natural properties, induction(s), and participation in laws, at least some of the ill organisms dealt with in somatic medicine form natural kinds in the same sense in which the kinds in the exact sciences are thought of as natural. By way of comparing two ‘divisions of nature’, viz., a ‘classical’ exact science kind (gold) and a kind of disease (Graves disease), I show (...) that there is no justifiable ‘ontological gap’ between disease kinds and exact sciences kinds. We have instead a difference of degree. (shrink)

This paper argues that a consideration of the problem of providing truthmakers for negative truths undermines truthmaker theory. Truthmaker theorists are presented with an uncomfortable dilemma. Either they must take up the challenge of providing truthmakers for negative truths, or else they must explain why negative truths are exceptions to the principle that every truth must have a truthmaker. The first horn is unattractive since the prospects of providing truthmakers for negative truths do not look good neither absences, nor totality (...) states of affairs, nor Graham Priest and J.C. Beall’s ‘polarities’ (Beall, 2000; Priest, 2000) are up to the job. The second horn, meanwhile, is problematic because restricting the truthmaker principle to atomic truths, or weakening it to the thesis that truth supervenes on being, undercuts truthmaker theory’s original motivation. The paper ends by arguing that truthmaker theory is, in any case, an under-motivated doctrine because the groundedness of truth can be explained without appeal to the truthmaker principle. This leaves us free to give the ommonsensical and deflationary explanation of negative truths that common-sense suggests. (shrink)

Realists about universals face a question about grounding. Are things how they are because they instantiate the universals they do? Or do they instantiate those universals because they are how they are? Take Ebenezer Scrooge. You can say that Scrooge is greedy because he instantiates greediness, or you can say that Scrooge instantiates greediness because he is greedy. I argue that there is reason to prefer the latter to the former. I develop two arguments for the view. I also respond (...) to some concerns one might have about the view defended. I close by showing that analogous views regarding the truth of propositions and the existence of facts are supported by analogs of one of these arguments. (shrink)

Since Aristotle, touch has been found especially hard to define. One of the few unchallenged intuition about touch, however, is that tactile awareness entertains some especially close relationship with bodily awareness. This article considers the relation between touch and bodily awareness from two different perspectives: the body template theory and the body map theory. According to the former, touch is defined by the fact that tactile content matches proprioceptive content. We raise some objections against such a bodily definition of touch (...) and suggest, as an alternative, to revive the proposal according to which touch is essentially a sense of pressure. According to the body map theory, tactile sensations are localized within the frame of reference provided by the mental representation of the space of the body. We argue that this approach of the location of bodily sensations fares better that the Local Sign theory that denies intrinsic spatiality to touch. (shrink)

Consider the kinds of macroscopic concrete objects that common sense and the sciences allege to exist: tables, raindrops, tectonic plates, galaxies, and the rest. Are there any such things? Opinions differ. Ontological liberals say they do; ontological radicals say they don't. Liberalism seems favored by its plausible acquiescence to the dictates of common sense abetted by science; radicalism by its ontological parsimony. Priority theorists claim we can have the virtues of both views. They hold that tables, raindrops, etc., exist, but (...) they aren't fundamental. The ontological liberal's ontology provides the correct inventory of existent individuals. The ontological radical's more restricted ontology provides the correct inventory of fundamental individuals. The priority theorist claims that the derivative individuals are "no addition in being" to the fundamental ones, so we can have our cake and eat it too. It would be nice if priority theorists were right. In this paper I argue, with regret, that they are not. One upshot is that the sort of explanations which underwrite the priority theorist's distinction between fundamental and derivative individuals do not mitigate our ontological commitments. Another is that we still have to choose between the charms of liberalism and radicalism. (shrink)

The bundle theory is a theory about the internal constitution of individuals. It asserts that individuals are entirely composed of universals. Typically, bundle theorists augment their theory with a constitutional approach to individuation entailing the thesis ‘identity of constituents is a sufficient ground for numerical identity’ (CIT). But then the bundle theory runs afoul of Black’s duplication case—a world containing two indiscernible spheres. Here I propose and defend a new version of the bundle theory that denies ‘CIT’, and which instead (...) conjoins it with a structural diversity thesis , according to which being separated by distance is a sufficient ground for numerical diversity. This version accommodates Black’s world as well as the three-spheres world —a world containing three indiscernible spheres, arranged as the vertices of an equilateral triangle. In this paper, I also criticize Rodriguez-Pereyra’s alternative attempt to defend the bundle theory against Black’s case and the case of the three-spheres world. (shrink)

Ockham’s Razor advises us to not multiply entities without necessity. Recently, Jonathan Schaffer and Karen Bennett have argued that we ought to replace Ockham’s Razor with the Laser, the principle that only advises us to not multiply fundamental entities without necessity. In this paper, I argue that Ockham’s Razor is preferable to the Laser. I begin by contending that the arguments offered for the Laser by Schaffer and Bennett are unpersuasive. Then I offer two cases of theory assessment that I (...) believe the Razor handles better than the Laser. Finally, I argue that accepting the Laser gives rise to a difficult explanatory challenge: It is difficult to explain why fundamental entities and non-fundamental entities ought to be treated differently in ontological parsimony assessments. A recurring secondary theme of the paper is that the most tempting ways of responding to my arguments frequently result in the Laser losing much of its significance for debates about ontology. Thus, not only is it difficult to defend a preference for the Laser over the Razor, but it is especially difficult to do so while maintaining the Laser’s dialectical significance. (shrink)

We naturally think of the material world as being populated by a large number of individuals . These are things, such as my laptop and the particles that compose it, that we describe as being propertied and related in various ways when we describe the material world around us.

I then propose and defend an individual-less view of the material world I call (...) “generalism”. (shrink)

In this paper I show that we have strong empirical and theoretical reasons to treat the verbs we use in our semantic theorizing—particularly ‘refers to ’, ‘applies to ’, and ‘is true of ’—as intensional transitive verbs. Stating our semantic theories with intensional vocabulary allows us to partially reconcile two competing approaches to the nature and subject-matter of semantics: the Chomskian approach, on which semantics is non-relational, internalistic, and concerns the psychology of language users, and the Lewisian approach, on which (...) semantics is fully relational, specifies truth-conditions, and has metaphysical implications. ITVs have two readings: an intensional, de dicto reading, and a relational, de re reading. A semantic theory stated with the de dicto readings of our semantic verbs captures the core insights of the Chomskian approach to semantics, in part because it allows us to assign extremely fine-grained semantic values to expressions, even when those expressions are empty. On the other hand, the de re reading yields a theory that is fully relational, and issues in truth-conditions. The resulting theories are related—and compatible—in that they are expressed by two different readings of the very same semantic vocabulary, and plausibly, the distinction between these two readings is one of scope.

The aim of this paper is to offer two novel solutions to two perennial problems of categorial ontology, namely, the problem of the categorial structure: how are the categories related to one another? And the problem of categorial completeness: how is the completeness of a proposed list of categories justified? First, I argue that a system of categories should have a structure such that there is a most basic category that is a bearer of all other categories and that has (...) what I shall call “combinatorial conditions”. To do so, I compare this approach to categorial structure with the approaches given by substantialist, mereological, factualist, and geo ontologies. Second, I argue that the problem of categorial completeness is only a problem for certain ontologies. In this connection, I explore views on categorial completeness proposed by substantialists and geo-ontologists. Lastly, I conclude that factualism does a better job of accounting for categorial structure and categorial completeness than other categorial ontologies. (shrink)

Since the publication of Universals and Scientific Realism (Armstrong 1978a, b) until Sketch for a Systematic Metaphysics (Armstrong 2010), via Universals: An Opinionated Introduction (Armstrong 1989), a World of States of Affairs (Armstrong 1997), and Truth and Truthmakers (Armstrong 2004), David Armstrong has developed one of the most influential theories of instantiation in contemporary analytic metaphysics (see, for example, Lewis, in Aust J Phil 61(4), 343–377, 1983; Baxter in Aust J Phil, 79, 449–464, 2001; Forrest, in Aust J Phil, 83, (...) 213–228, 2006). Instantiation has been advocated by Armstrong to give a solution to what he has called the “pressing problem” of “the multiple location of property universals” (Armstrong, in Universals: An opinionated introduction. University Press, Cambridge, 1989, pp. 89–90). Here I argue that Armstrong’s theory of instantiation fails to solve the problem because it involves two kinds of instantiation to account for particulars “having” and “sharing” universals. As a viable alternative to Armstrong’s theory, I propose a theory of instantiation capable of accounting for both phenomena in a univocal way. (shrink)

For over 20 years, Jaegwon Kim’s Causal Exclusion Argument has stood as the major hurdle for non-reductive physicalism. If successful, Kim’s argument would show that the high-level properties posited by non-reductive physicalists must either be identical with lower-level physical properties, or else must be causally inert. The most prominent objection to the Causal Exclusion Argument—the so-called Overdetermination Objection—points out that there are some notions of causation that are left untouched by the argument. If causation is simply counterfactual dependence, for example, (...) then the Causal Exclusion Argument fails. Thus, much of the existing debate turns on the issue of which account of causation is appropriate. In this paper, however, I take a bolder approach and argue that Kim’s preferred version of the Causal Exclusion Argument fails no matter what account one gives of causation. Any notion of causation that is strong enough to support the premises of the argument is too strong to play the role required in the logic of the argument. I also consider a second version of the Causal Exclusion Argument, and suggest that although it may avoid the problems of the first version, it begs the question against a particular form of non-reductive physicalism, namely emergentism.
