Are the sparse properties drawn from all the levels of nature, or only the fundamental level? I discuss the notion of sparse property found in Armstrong and Lewis, show that there are tensions in the roles they have assigned the sparse properties, and argue that the sparse properties should be drawn from all the levels of nature.

Commitment to sparseness amounts to the idea that there is an objective, worldly privileging of certain properties over others that makes the privileged properties suited to play certain roles, and is responsible for their playing such roles. In this chapter I offer a brief, opinionated overview of sparseness. I begin by examining a set of problems that I call “problems of abundance”, which generate canonical motivations for sparseness. I then survey some influential approaches to sparseness and the roles (...) that they attribute to sparse properties, noting that on most approaches sparse properties are deeply connected to inquiry. Finally I consider some problems for sparseness, focusing on the purported connections between sparseness and inquiry, particularly in philosophy of science and inquiry into the social world.

Zombies are bodies without minds: creatures that are physically identical to actual human beings, but which have no conscious experience. Much of the consciousness literature focuses on considering how threatening philosophical reflection on such creatures is to physicalism. There is not much attention given to the converse possibility, the possibility of minds without bodies, that is, creatures who are conscious but whose nature is exhausted by their being conscious. We can call such a ‘purely conscious’ creature a ghost.

Setting off from a familiar distinction in the philosophy of properties, this paper introduces a tripartite distinction between sparse causation, abundant causation and mere abundant causation. It is argued that the contrast between sparse and mere abundant causation allows us to resolve notorious philosophical issues having to do with negative causation, causation involving institutional properties and physical macro-causation in a way that is unified, intuitive and in line with scientific doctrines and practices.

Those who hold that all fundamental sparse properties have dispositional essences face a problem with structural (e.g. geometrical) properties. In this paper I consider a further route for the dispositional monist that is enabled by the requirement that physical theories should be background-free. If this requirement is respected then we can see how spatial displacement can be a causally active relation and hence may be understood dispositionally.

One of the many ways that ‘deflationary’ and ‘inflationary’ theories of truth are said to differ is in their attitude towards truth qua property. This difference used to be very easy to delineate, with deflationists denying, and inflationists asserting, that truth is a property, but more recently the debate has become a lot more complicated, owing primarily to the fact that many contemporary deflationists often do allow for truth to be considered a property. Anxious to avoid inflation, however, these deflationists (...) are at pains to point out that the truth property, on their view, is not a property of any significant interest. Correspondingly, inflationists have seen this as an opportunity to refine what kind of property they think truth is, which—according to them—moves their views beyond deflationism. The upshot of this is that there are number of different accounts in the literature of what distinguishes an inflationary truth property from a deflationary one, or—as it is sometimes put—what distinguishes a ‘substantive’ property from an ‘insubstantive’ one. This has made it hard to pin down exactly what is at issue at the metaphysical level between deflationists and inflationists, which makes it increasingly hard to see how debates between them are properly phrased. Given that these positions represent the two central attitudes towards truth in contemporary debates, this makes for a serious obstacle for the project of discerning the correct theory of truth. The aim of this paper is to discern the best way to distinguish between substantive and insubstantive properties, and thus to restore some focus to these debates. I argue that the three central distinctions in the literature fail, and offer what I take to be a more promising distinction in terms of a graded distinction between abundant and sparse properties.

Dispositional essentialism maintains that all sparse properties are essentially powerful. Two conceptions of sparse properties appear compatible with dispositional essentialism: sparse properties as pure powers or as powerful qualities. This paper compares the two views, criticizes the powerful qualities view, and then develops a new theory of pure powers, termed Point Theory. This theory neutralizes the main advantage powerful qualities appear to possess over pure powers—explaining the existence of powers during latency periods. The paper (...) discusses the relation between powers and space-time points, whether pure powers need to occupy space, and how to account for the movement of pure powers through space-time. Given Point Theory, dispositional essentialists should maintain that sparse properties are pure powers. (shrink)

In the past fifteen years or so there has been a lot of attention paid to theories of “sparse” universals, particularly because of the work of D. M. Armstrong. These theories are of particular interest to those of us concerned with the distinction between natural and non-natural properties, since, as David Lewis has observed, it seems possible to analyze naturalness in terms of sparse universals. Moreover, Armstrong claims that we should conceive of universals as being “immanent” as (...) opposed to “transcendent”, and if universals are immanent then, as we will see, there is pressure to admit they are sparse as well. But I will argue that neither of these alleged reasons to accept a sparse conception of universals succeeds: the outlook for a fully general analysis of naturalness in terms of universals is not good, and the apparent advantages of immanence over transcendence are illusory.

This paper defends the case against (sparse) disjunctive properties by means of four Armstrongian arguments. The first of these is a logical atomist argument from truthmaking, which is, broadly speaking, ‘Armstrongian’ (Armstrong 1997). This argument is strong – although it stands or falls with the relevant notion of truthmaking, as it were. However, three arguments, which are prima facie independent of truthmaking, can be found explicitly early in Armstrong’s middle period. Two of these early arguments face a serious (...) objection put forward forcefully by Louise Antony (2003) and Alan Penczek (1997), respectively. I consider these objections and argue that they fail. Thus, even if the argument from truthmaking is indecisive, disjunctive properties should be rejected. (shrink)

The advent of digital cameras has provided photographers, with varying levels of expertise, the opportunity to accumulate large repositories of digital images. However, this expansion has also brought the attendant difficulty of image retrieval. This paper reviews the considerable work already carried out on image retrieval and identifies critical constraints in attempting to handle the underlying semantics of photographic images. The authors address the issue of how an amateur photographer, storing several thousand images a year, can effectively and efficiently manage (...) a personal collection. A number of surprisingly simple techniques are proposed utilising a sparse lexical ontology alongside iconic visual clues to identify key representative events in the collection. The photographer’s associated knowledge and experience, often shared by others who are attuned to the context of the collection, are critical to the effective management of the images. The authors recommend the use of existing browsers and a simple keyword table to facilitate concise and effective image storage and retrieval. Photographers can further enrich the representation of their collection by clustering images in accordance with their perceived relevance and aesthetic qualities. The authors argue that these properties can also be exploited to enhance retrieval. (shrink)

This paper presents a puzzle or antinomy about the role of properties in causation. In theories of properties, a distinction is often made between determinable properties, like red, and their determinates, like scarlet (see Armstrong 1978, volume II). Sometimes determinable properties are cited in causal explanations, as when we say that someone stopped at the traffic light because it was red. If we accept that properties can be among the relata of causation, then it can (...) be argued that there are good reasons for allowing that some of these are determinable properties. On the other hand, there are strong arguments in the metaphysics of properties to treat properties as sparse in David Lewis’s (1983) sense. But then it seems that we only need to believe in the most determinate properties: particular shades of colour, specific masses, lengths and so on. And if we also agree with Lewis that sparse properties are ‘the ones relevant to causal powers’ (1983: 13) it seems we must conclude that if properties are relevant to causation at all, then all of these are determinate properties. I call this ‘the antinomy of determinable causation’. On the one hand, we have a good argument for the claim that determinable properties can be causes, if any properties are. I call this the Thesis. But on the other hand, we have a good argument for the claim that only the most determinate properties can be causes, if any properties are. I call this the Antithesis.

What determines qualitative sameness and difference? This book explores four principal accounts of the ontological basis of properties, including universals, trope theory, resemblance nominalism, and class nominalism, considering the assumptions and ontolological commitments which are required to make each into a plausible account of properties. -/- The latter half of the book investigates the applications of property theory and the different conceptions of properties which might be adopted with these in mind: first, the possibility and desirability of (...) individuating properties, and the distinction between sparse and abundant conceptions of properties; second, the distinction between intrinsic and extrinsic properties; third, the relationship between properties and their causal powers, and whether this is necessary or contingent; fourth, the relationship between properties and causation, modality, and laws of nature; finally, whether properties exist objectively, and if they do, what our epistemic position is with respect to such entities.

This dissertation develops and defends a detailed realist, internalist account of qualia which is consistent with physicalism and which does not resurrect the epistemological 'myth of the Given.' In doing so it stakes out a position in the sparsely populated middle ground between the two major opposing factions on the problem of phenomenal consciousness: between those who think we have a priori reasons to believe that qualia are irreducible to the physical , and those who implicitly or explicitly treat qualia (...) as contentful but non-phenomenal physical properties . ;I present a minimal, non-question-begging definition of "qualia" and then use this definition in a reformulation of the argument from perceiver relativity which shows that qualia must, at least in humans, be properties of states of the central nervous system. That is, brain states do not simply indicate the colours of external objects---they instantiate phenomenal colours. Since brain states are not coloured in the same way as are external objects, I argue that to token phenomenal property F must be to be the first-person phenomenal sensation of F. I build on this position to argue that the phenomenal apprehension of qualia, is "given"---immediate, certain and private---but that qualia nevertheless do not provide an absolutely certain epistemological foundation since they do not constitute a set of indisputable propositions about facts. I then define what it would be for physicalism to be true of qualia, but argue that the main a priori arguments for and against qualia physicalism---including the logical possibility of zombies and the impossibility of epiphenomenalism---fail. Whether qualia are consistent with physicalism, I claim, is still an open question, answerable only when we discover in more detail how qualia depend upon the brain. ;Although strongly in sympathy with many commonsensical intuitions about qualia, this account stands in contrast to most influential extant theories of qualia, such as eliminativism , externalism , or property-dualism : I conclude the dissertation by using its results to argue explicitly against these three positions.

This paper presents an account of what it is for a property or relation (or ‘attribute’ for short) to be logically simple. Based on this account, it is shown, among other things, that the logically simple attributes are in at least one important way sparse. This in turn lends support to the view that the concept of a logically simple attribute can be regarded as a promising substitute for Lewis’s concept of a perfectly natural attribute. At least in part, (...) the advantage of using the former concept lies in the fact that it is amenable to analysis, where that analysis—i.e., the account put forward in this paper—requires the adoption neither of an Armstrongian theory of universals nor of a primitive notion of naturalness, fundamentality, or grounding.

The paper argues that the assumption that there are property designators, together with two theoretically innocent claims, leads to a puzzle, whose solution requires us to reject the position that all (canonical) property designators are rigid. But if we deny that all (canonical) property designators are rigid, then the natural next step is to reject an abundant conception of properties and with it the suggestion that properties are the semantic values of predicates.

This chapter is an edited transcription of an author-meets-critics session at the Truth 20|20 Conference, on Douglas Edwards’ award-winning book, The Metaphysics of Truth (2018, Oxford University Press). The Metaphysics of Truth tackles fundamental questions about the role of truth in connections between language and the world. Edwards proposes a pluralist account, according to which sentences in different domains get to be true in different ways. Kellen’s questions center around how to locate Edwards’s pluralist account given certain distinctions between varieties (...) of truth pluralism, and on how to determine what domains certain sentences belong to, especially mixed compounds. Taylor’s comments critically investigate Edwards’ critiques of deflationism, particularly to do with what the deflationist can say about whether truth counts as a ‘sparse’ or ‘abundant’ property, and whether deflationists are able to explain important differences between sparse properties such as being magnetic, and abundant properties, which deflationists will likely think include being true. Lynch provides several questions about the metaphysics of Edwards’s account, including the nature of the determination relation, and the nature of the property of truth itself, and whether Edwards’s account of that property manages to distinguish itself from something a truth minimalist would be happy with.

It’s a platitude that a picture is realistic to the degree to which it resembles what it represents (in relevant respects). But if properties are abundant and degrees of resemblance are proportions of properties in common, then the degree of resemblance between different particulars is constant (or undefined), which is inconsonant with the platitude. This paper argues this problem should be resolved by revising the analysis of degrees of resemblance in terms of proportion of properties in common, (...) and not by accepting a sparse theory of properties or by denying that degree of realism is degree of resemblance (in relevant respects).

Sparse knowledge exists about measuring spiritual, religious, and existential (SRE) constructs in children. Well-validated questionnaires measuring such concepts are necessary when researchers want to quantitatively investigate the spiritual lives of children. We aimed to identify questionnaires measuring SRE constructs in children and assess their psychometric properties. We conducted literature searches in four electronic databases. Studies were included if they described the use of a questionnaire measuring SRE constructs in children under 12 years. Systematic data extraction and assessment of (...) the studies using standardized COSMIN guidelines were performed. A total of 17,681 records were screened. Twenty-seven articles assessing 18 different questionnaires met the inclusion criteria. In total, 16 structural validity, 20 internal consistency, 4 measurement invariance, and 16 construct validity studies were found. We identified no high-quality content validity studies. The Meaning in Life in Children Questionnaire by Shoshani and Russo-Netzer showed promising measurement properties. However, all included instruments need further content validity testing before being recommended for use. (shrink)

I argue that there is no metaphysically substantive property of truth. Although many take this thesis to be central to deflationism about truth, it is sometimes left unclear what a metaphysically substantive property of truth is supposed to be. I offer a precise account by relying on the distinction between the property and concept of truth. Metaphysical substantivism is the view that the property of truth is a sparse property, regardless of how one understands the nature of sparse (...) properties. I then offer two new arguments against metaphysical substantivism that employ ideas involving recombination and truthmaking. First, I argue that there are no theoretically compelling reasons to posit the existence of a metaphysically substantive property of truth. Secondly, I argue that if we do posit the existence of such a property, then we end up with a view that is either contradictory or unmotivated. What we’re left with is a metaphysically deflationary account of the property of truth that fully respects the metaphysical ambitions of truthmaker theory, and that is consistent with both the view that truth is a deflated, explanatorily impotent concept and the view that truth is an explanatorily powerful concept.

The existence of complex predicates seems to support an abundant conception of properties. Specifically, the application conditions for complex predicates seem to be explained by the distribution of a sparser base of predicates. This explanatory link might suggest that the existence and distribution of properties expressed by complex predicates are explained by the existence and distribution of a sparser base of properties. Thus, complex predicates seem to legitimize the assumption of a wide array of properties. The (...) additional properties are no explanatory addition to the sparse base. I argue, however, that construing complex predicates as expressing properties undermines the explanatory links between simple and complex predications. The argument explores a variety of accounts of complex predicates currently on offer and develops a number of themes from the work of Herbert Hochberg. (shrink)

According to the powerful qualities view, properties are both powerful and qualitative. Indeed, on this view the powerfulness of a property is identical to its qualitativity. Proponents claim that this view provides an attractive alternative to both the view that properties are pure powers and the view that they are pure qualities. It remains unclear, however, whether the claimed identity between powerfulness and qualitativity can be made coherent in a way that allows the powerful qualities view to constitute (...) this sort of alternative. I argue here that this can be done, given a particular conception of both the qualitativity and powerfulness of properties. On this conception, a property is qualitative just in the sense that its essence is fixed independently of any distinct properties, and it is powerful just if its essence grounds its dispositional role.

There are at least two traditional conceptions of numerical degree of similarity. According to the first, the degree of dissimilarity between two particulars is their distance apart in a metric space. According to the second, the degree of similarity between two particulars is a function of the number of (sparse) properties they have in common and not in common. This paper argues that these two conceptions are logically independent, but philosophically inconsonant.

Metaphysicians often distinguish between joints and basic ways. Joints are the unified and joint-carving properties that trace the structure of the world. They are theorized under the ideology of structural, perfectly natural, or sparse properties. Basic ways are the ultimate and independent properties that give rise to all others. They are theorized under the ideology of grounding, where the ungrounded properties are the basic ways. While these notions are often seen as rivals, I argue that (...) we need both, because the joints and the basic ways crosscut. For the sake being exhaustive and ecumenical, I distinguish between natural and normative sorts of joints and basic ways. I argue that, for either sort, if there is such a sort of joint and basic way, then there are joints that are not basic ways and there are basic ways that are not joints. (shrink)

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

Rather infamously, Kit Fine provided a series of counter‐examples which purport to show that attempts to understand essence in terms of metaphysical necessity are ‘fundamentally misguided’. Here, my aim is to put forward a new version of modalism that is, I argue, immune to Fine's counter‐examples. The core of this new modalist account is a sparseness restriction, such that an object's essential properties are those sparse properties it has in every world in which it exists. After first (...) motivating this sparseness restriction, I proceed to show how the resulting sparse modalism circumvents Fine's original counter‐examples. After dismissing a potential problem concerning the membership relation, I conclude that, as at least one form of modalism is viable, the project of understanding essence in terms of metaphysical necessity is not so fundamentally misguided after all. (shrink)

According to the simple modal account of essence, an object has a property essentially just in case it has it in every world in which it exists. As many have observed, the simple modal account is implausible for a number of reasons. This has led to various proposals for strengthening the account, for example, by adding a restriction to the intrinsic or sparse properties. I argue, however, that these amendments to the simple modal account themselves fail. Drawing on (...) lessons from these failures, I propose a new version of a modal account, inspired by Ruth Barcan Marcus's defense of the coherence of quantified modal logic, according to which an object has a property essentially just in case (i) it has it in every world in which it exists, (ii) the property is discriminating (or non-trivial), and (iii) the property is qualitative. The resulting account of essence does not face any of the standard objections other accounts face, and I defend it from other potential objections. (shrink)

Let us call a property that is essentially dispositional a potency.1 David Armstrong thinks that potencies do not exist. All sparse properties are essentially categorical, where sparse properties are the explanatory properties of the type science seeks to discover. An alternative view, but not the only one, is that all sparse properties are potencies or supervene upon them. In this paper I shall consider the differences between these views, in particular the objections Armstrong (...) raises against potencies. (shrink)

Alexander Bird puts forward a modest version of anti-Humeanism about the non-fundamental, by providing an argument for the existence of a certain select class of non-fundamental but sparse dispositions: those that have an evolutionary function. I argue that his argument over-generates, so much so that the sparse–abundant distinction, and with it the tenet of his anti-Humean view, becomes obsolete. I suggest an alternative way of understanding anti-Humeanism in the non-fundamental realm, one which is not concerned with the existence (...) of sparse properties but with explanatory relations.

Several philosophers of science and metaphysicians claim that the dispositional properties of fundamental particles, such as the mass, charge, and spin of electrons, are ungrounded in any further properties. It is assumed by those making this argument that such properties are intrinsic, and thus if they are grounded at all they must be grounded intrinsically. However, this paper advances an argument, with one empirical premise and one metaphysical premise, for the claim that mass is extrinsically grounded and (...) is thus an extrinsic disposition. Although the argument concerns mass characterized as a disposition, it applies equally well whether mass is a categorical or dispositional property; however, the dispositional nature of mass is relevant to some important objections and implications discussed.

The notion of similarity plays a central role in Quine's theory of Universals and it is with the help of this notion that Quine intends to define the concept of kind which also plays a central role in the theory. But as Quine has admitted, his attempts to define kinds in terms of similarities were unsuccessful and it is mainly because of this shortcoming that Quine's theory has been ignored by several philosophers. Nominalism and realism: Universals and Scientific realism. Cambridge: (...) Cambridge University Press).

The framework agrees with Quine's austere ontology; in particular, it does not assume the existence of properties and of possible worlds.. Resemblance nominalism: A solution to the problem of Universals. Oxford: Clarendon Press.) Moreover, the framework is extensionalist since the abstract entities it assumes are classes and these can be individuated extensionally, for classes are identical if their members are identical.

Mind, 105, 1-80.] and I will argue that, contrary to what has been claimed by Oliver in a comment on Lewis [. On the plurality of worlds. Oxford: Blackwell.], Quine is able to specify an important set of sparse properties. (shrink)

Fine is widely thought to have refuted the simple modal account of essence, which takes the essential properties of a thing to be those it cannot exist without exemplifying. Yet, a number of philosophers have suggested resuscitating the simple modal account by appealing to distinctions akin to the distinction Lewis draws between sparse and abundant properties, treating only those in the former class as candidates for essentiality. I argue that ‘sparse modalism’ succumbs to counterexamples similar to (...) those originally posed by Fine, and fails to capture paradigmatic instances of essence involving abundant properties and relations.

As Rodriguez-Pereyra understands the Problem of Universals, solving it requires specifying the truthmakers of attributions of sparse properties to particulars, so as to resolve the “Many over One”—the puzzle of how the same particular can be different ways. According to Rodriguez-Pereyra, these truthmakers need not involve irreducible properties ; resemblances between particulars will do. Here I’ll set out Rodriguez-Pereyra’s version of resemblance nominalism and note certain of its problems, some of which can be answered with revisions that (...) he could, qua nominalist, accept, and others for which the solution is not so clear.

In The Metaphysics of Truth, Doug Edwards offers a sustained case against deflationism about truth and in favour of his preferred pluralist theory of truth. Here, I take up three of the main components of that case. The first is Edwards' account of the distinctive metaphysical commitments of deflationism. His views about this issue have changed over the past few years, and I detail these changes as well as a concern for the views that he develops in the book. Second, (...) I take up the argument that Edwards offers for thinking that deflationism is, in a certain sense, internally unstable. I explain why this argument is inconclusive, outlining three responses to it on behalf of the deflationist. Third, I consider Edwards' novel argument for truth pluralism, which acts as an indirect argument against deflationism. After sorting out some interpretive nuances related to the use of definite descriptions in this argument, I show how the deflationist can resist it. Having responded to Edwards' critique of deflationism, I close by briefly explaining why I take the methodology of deflationism to be especially promising, insofar as it underscores the significance of empirically-informed inquiry about truth.

According to traditional universalism, properties are instantiated by objects, where instantiation is a ‘tie’ that binds objects and properties into facts. I offer two arguments against this view. I then develop an alternative higher-order account which holds that properties are primitively predicated of objects yet, unlike traditional nominalism, are nevertheless genuinely real. When it’s a fact that Fo, it’s not because object o instantiates F-ness, but just that Fo – where F still exists. Against orthodox higher-order approaches, (...) however, my arguments against instantiation also serve to support a sparse conception of properties. In developing the view, I introduce an extension of ontological and ideological commitment in the form of syntactic commitment. (shrink)

David Lewis is typically interpreted as a class nominalist. One consequence of class nominalism, which he embraced, is that the reduction of ordered pairs, triples, etc to unordered sets of sets is conventional. The reaction by his Australian counterparts D.M. Armstrong and Peter Forrest was that Lewis was not being ontologically serious. This chapter evaluates this debate over serious ontology. It is argued that in one sense Lewis is ontologically serious, but that his additional commitment to structuralism about classes should (...) push him to adopt a trope-theoretic account of naturalness, which opens up another way to respond to the charge of not doing serious ontology. This conclusion is supported by certain remarks he makes in his correspondence, thus revealing how his thinking about properties appears to have evolved from property-egalitarianism to a sparse theory of tropes.

This paper deals with the issue of the admissible content of perceptual experience at the centre of the debate that opposes Conservatives and Liberals —who advocate, respectively, a Sparse and a Rich Content-View— and aims, specifically, to consider how this debate interacts with the Externalism/Internalism debate in philosophy of perception. Indeed, apart from a few exceptions (Siegel, 2006, 2010, 2013; Bayne, 2009; Ashby, 2020a; Raleigh, 2022), this issue has not yet been sufficiently addressed, and the present paper, in the (...) wake of the aforementioned works, aims to focus on this issue in order to assess whether it would be more congenial for a Liberal to adopt content internalism or rather content externalism. In my paper I argue that the best move the Liberal should make is to endorse externalism with regard to the content of perceptual experience and internalism with regard to its phenomenal character. But, as it will turn out, this combination can only be sustained consistently if the Liberal discards the standard interpretation of one of its central claims, the so-called (Ashby, 2020a, p. 689) “phenomenal reflection claim” (PRC) —the claim according to which perceptual properties are reflected in/reverberate in the phenomenology of the experience— and adopts a different interpretation of it. To indicate what alternative interpretation of PRC the liberal should provide is one of the main goals of the paper. (shrink)

A critical property of the perception of spoken words is the transient ambiguity of the speech signal. In localist models of speech perception this ambiguity is captured by allowing the parallel activation of multiple lexical representations. This paper examines how a distributed model of speech perception can accommodate this property. Statistical analyses of vector spaces show that coactivation of multiple distributed representations is inherently noisy, and depends on parameters such as sparseness and dimensionality. Furthermore, the characteristics of coactivation vary considerably, (...) depending on the organization of distributed representations within the mental lexicon. This view of lexical access is supported by analyses of phonological and semantic word representations, which provide an explanation of a recent set of experiments on coactivation in speech perception (Gaskell & Marslen–Wilson, 1999).

According to Sparse views of perceptual content, the phenomenal character of perceptual experience is exhausted by the experiential presentation of ‘low-level’ properties such as (in the case of vision) shapes, colors, and textures Whereas, according to Rich views of perceptual content, the phenomenal character of perceptual experience can also sometimes involve experiencing ‘high-level’ properties such as natural kinds, artefactual kinds, causal relations, linguistic meanings, and moral properties. An important dialectical tool in the debate between Rich and (...) Sparse theorists is the so-called ‘method of phenomenal contrast’. I explore how this method of phenomenal contrast interacts with the sort of content-externalism made familiar by Putnam. I show that the possibility of Twin Earth style cases places important restrictions on the range of properties that the method of phenomenal contrast could plausibly apply to. Moreover, these restrictions would apply to some paradigmatically low-level properties as well as to some of the frequently advanced high-level properties. I also draw some general lessons about the different ways one might conceive of the relation between phenomenal character and representational content. (shrink)

According to sparse modalism, the notion of essence can be analysed in terms of necessity and naturalness. In this paper, I develop and defend a version of sparse modalism that is equipped with a non-standard, relativized conception of naturalness. According to this conception, properties and relations can be natural to different degrees relative to different kinds of things, and relations can be natural to different degrees relative to different slots. I argue that this relativized version of (...) class='Hi'>sparse modalism can accommodate various cases that the standard, non-relativized version can’t. The alternative version can accommodate cases where a relation is essential to a relatum but merely necessary to another, cases where a property is essential to an object but merely necessary to another, and cases where a less-than-perfectly natural property is essential to an object.

I believe in an immense realm of "modal" and "abstract" entities, of entities that are neither part of, nor stand in any causal relation to, the actual, concrete world. For starters: I believe in possible worlds and individuals; in propositions, properties, and relations (both abundantly and sparsely conceived); in mathematical objects and structures; and in sets (or classes) of whatever I believe in. Call these sorts of entity, and the reality they (...) comprise, metaphysical. In contrast, call the actual, concrete entities, and the reality they comprise, physical. Physical and metaphysical reality together comprise all that there is. In this paper, it is not my aim to defend realism about any particular metaphysical sort of entity. Rather, I ask quite generally whether and how any brand of realism about metaphysical sorts of entity could be justified? (shrink)

In these replies I develop responses to the fascinating issues raised in the commentaries on my book The Metaphysics of Truth from Matti Eklund, Gila Sher, Crispin Wright, and Jeremy Wyatt. I focus on four main areas where there seemed to be a degree of convergence amongst the critics: (1) the viability and use of the sparse/abundant property distinction; (2) truth, dependence, and superassertibility; (3) correspondence, realism, and anti—realism; and (4) my ‘globalizing’ argument against deflationism.

Here I offer a critical evaluation of modalism about essential properties. To that effect, I begin by rehearsing Fine’s now infamous counterexamples to pure modalism. I then consider two recent defenses of it, offered by Livingstone-Banks and Cowling, respectively. I argue that both defenses fail. Next I consider the most plausible variety of impure modalism – sparse modalism – which has recently been defended by Wildman and de Melo. Skiles has argued that sparse modalism fails too. I (...) argue that Skiles’s counterexamples misfire; nonetheless, his conclusion that, like pure modalism, sparse modalism is too broad, is on the right track. And so, I offer an original objection – the sparse modal propria counterexample – to show that this is so. I conclude by considering ways the modalist might once again modify her account to circumvent this new objection and improve the account’s extensional adequacy. (shrink)

According to Satosi Watanabe's "theorem of the ugly duckling", the number of predicates satisfied by any two different particulars is a constant, which does not depend on the choice of the two particulars. If the number of predicates satisfied by two particulars is their number of properties in common, and the degree of resemblance between two particulars is a function of their number of properties in common, then it follows that the degree of resemblance between any two different (...) particulars is also constant, which is absurd. Avoiding this absurd conclusion requires questioning assumptions about infinity in the proof or interpretation of the theorem, adopting a sparse conception of properties, or denying degree of resemblance is a function of number of properties in common. After arguing against both the first two options, this paper argues for a version of the third which analyses degree of resemblance as a function of properties in common, but weighted by their degree of naturalness or importance.
