According to one popular criterion of property identity, where X and Y are properties, X is identical with Y if and only if X and Y bestow the same conditional powers on their bearers. In this paper, I argue that this causal criterion of property identity is unsatisfactory, because it fails to provide a sufficient condition for the identification of properties. My argument for this claim is based on the observation that the summing of properties does not entail the summing (...) of the conditional powers that they bestow on an object, but, rather, in some cases their subtraction. If so, the following causal structure seems possible: There are two properties, A and B. Each bestows a different set of conditional powers on its bearer, but the conjunctive property A-and-B bestows exactly the same set of conditional powers as either A or B. If this causal structure is possible, then it creates a serious problem for the causal criterion of property identity. (shrink)

I consider the first part of Marty’s Raum und Zeit, which treats of both the nature of space and spatial perception. I begin by sketching two charges that Marty raises against Kantian and Brentanian conceptions of space (and spatial perception) respectively, before detailing what I take to be a characteristically Martyan picture of space perception, though set against the backdrop of contemporary philosophy of perception. Marty has it that spatial relations are non-real but existent, causally inert relations that are grounded (...) in space, which is itself non-real but existent. Objects do not inhere in space in the way properties inhere in substances. Rather, there is a ‘non-real’ relation of ‘fulfillment’ (Erfüllung) that holds between objects and places in space, which itself subsists. I consider whether any contemporary philosophy of perception is equipped to make sense of Martyan space perception and I suggest that the most promising conception is Naïve Realism. I then outline a difficulty for this theoretical translation. Naïve Realism is a direct theory of perception whereby S is said to perceive O just in case S stands in a psychological relation of acquaintance with O, where this relation is both non-representational and explanatorily primitive. For Marty however, all relations are non-real and, insofar as they are grounded, are neither fundamental, nor brute or primitive in an explanatory sense. I close by detailing what I thereby take a distinctively Martyan form of Naïve Realism to involve. The central theoretical tenet that phenomenal character is fundamentally constituted by worldly objects is preserved; but the manifestly relational structure of the acquaintance relation, construed in particular as a relation of awareness, is treated as derivative. I make headway in spelling out the latter claim by bringing Marty into fleeting conversation with another Thomist - G.E.M. Anscombe. (shrink)

Often when one omits to do a certain thing, there's no action that is one's omission; one's omission, it seems, is an absence of any action of some type. This paper advances the view that an absence of an action--and, in general, any absence--is nothing at all: there is nothing that is an absence. Nevertheless, it can result from prior events that one omits to do a certain thing, and there can be results of the fact that one omits to (...) do something. This is so even if absences cannot be causes or causal effects. (shrink)

This paper attempts to locate, within an actualist ontology, truthmakers for modal truths: truths of the form or . In Sect. 1 I motivate the demand for substantial truthmakers for modal truths. In Sect. 21 criticise Armstrong's account of truthmakers for modal truths. In Sect. 31 examine essentialism and defend an account of what makes essentialist attributions true, but I argue that this does not solve the problem of modal truth in general. In Sect. 41 discuss, and dismiss, a theistic (...) account of the source of modal truth proposed by Alexander Pruss. In Sect. 5 I offer a means of (dis)solving the problem. (shrink)

When there is truth, there must be some thing (or things) to account for that truth: some thing(s) that couldn’t exist and the true proposition fail to be true. That is the truthmaker principle. True propositions are made true by entities in the mind-independently existing external world. The truthmaker principle seems attractive to many metaphysicians, but many have wanted to weaken it and accept not that every true proposition has a truthmaker but only that some important class of propositions require (...) truthmakers.1 Let us, following Armstrong, call the claim that all true propositions, without exception, have a truthmaker, Truthmaker Maximalism. Why might one be tempted to the spirit of truthmaker theory but reject Truthmaker Maximalism? Well, you might deny that necessary truths need truthmakers, for one, and insist that only contingent truths have truthmakers. But I think it’s fair to say that the most common motivation for rejecting maximalism concerns negative truths. The thought that negative truths are exempt from the demand for truthmakers could be justified in one of two ways: there is the claim that we don’t need truthmakers for negative truths, and there is the claim that we can’t have..

In some recent work on omissions, it has been argued that the causal theory of action cannot account for how agency is exercised in intentionally omitting to act in the same way it explains how agency is exercised in intentional action. Thus, causalism appears to provide us with an incomplete picture of intentional agency. I argue that causalists should distinguish causalism as a general theory of intentional agency from causalism as a theory of intentional action. Specifically, I argue that, while (...) intentional actions may best be understood as the causal products or outcomes of causings, we should identify exercises of intentional agency with causal processes. With a causalist account of intentional agency sketched, I respond to the challenge to causalism from omissions. I argue that when an agent intentionally omits there is a causal process that has a zero-sum outcome. But the causal process is sufficient to make it true that the agent exercises intentional agency in intentionally omitting. (shrink)

It is often thought that metaphysical grounding underwrites a distinctive sort of metaphysical explanation. However, it would be a mistake to think that all metaphysical explanations are underwritten by metaphysical grounding. In service of this claim, I offer a novel kind of metaphysical explanation called metaphysical explanation by constraint, examples of which have been neglected in the literature. I argue that metaphysical explanations by constraint are not well understood as grounding explanations.

This paper discusses a class of mechanistic explanations employed in engineering science where the activities and organization of nonstandard entities are cited as core factors responsible for failures. Given the use of mechanistic language by engineers and the manifestly mechanistic structure of these explanations, I consider several interpretations of these explanations within the new mechanical framework. I argue that these interpretations fail to solve several philosophical problems and propose an account of fictional mechanism explanations instead. According to this account, fictional (...) mechanism explanations provide descriptions of fictional mechanisms that enable the tracking of counterfactual dependencies of the physical system they model by capturing system constraints. Engineers use these models to learn about and understand properties of materials, to build computational simulations of their behaviour, and to design new materials. (shrink)

Recent discussion of the problem of negative existentials for truthmaker theory suggests a modest solution to the problem: fully general negative truths like do not require truthmakers, whereas partially general negative truths like do. This modest solution provides a third alternative to the two standard solutions to the problem of negative existentials: the endorsement of truthmaker gaps, and the appeal to contentious ontological posits. We argue that this modest, middle-ground position is inconsistent with certain plausible general principles for truthmaking. The (...) only stable positions are to treat all negative truths as requiring truthmakers, or admit that no negative truths require truthmakers. Along the way, we explore some previously unaddressed questions for nonmaximalist truthmaker theory. (shrink)

A common account of the distinction between analytic and synthetic truths is that while the former are true solely in virtue of meaning, the latter are true also in virtue of the way of the world. Quine famously disputed this characterization, and his skepticism over the analytic/synthetic distinction has cast a long shadow. Against this skepticism, I argue that the common account comes close to the truth, and that truthmaker theory in particular offers the resources for providing a compelling account (...) of the distinction that preserves the basic ideas behind it, and avoids the standard criticisms facing the distinction. In particular, I argue that analytic truths are truths that ontologically depend in no way whatsoever upon what exists. (shrink)

Truthmaker necessitarianism is the view that an object is a truthmaker for a truth-bearer only if it is impossible for the object to exist and the truth-bearer be false. While this thesis is widely regarded as truthmaking "orthodoxy", it is rarely explicitly defended. In this paper I offer an argument in favor of necessitarianism that raises the question of what the truthmakers are for the truths about truthmaking. The supposed advantages of non-necessitarianism dissolve once we take these truths into account.

It is a common criticism of presentism – the view according to which only the present exists – that it errs against truthmaker theory. Recent attempts to resolve the truthmaker objection against presentism proceed by restricting truthmaker maximalism (the view that all truths have truthmakers), maintaining that propositions concerning the past are not made true by anything, but are true nonetheless. Support for this view is typically garnered from the case for negative existential propositions, which some philosophers contend are exceptions (...) to truthmaker maximalism. In this article, we argue that a ‘no truthmakers’ approach to the truthmaker objection is critically flawed. (shrink)

Realism and anti-realism about a domain of thought are metaphysical theses that involve the natures of the truthmakers in that domain and the truthmaking relation that is operant in the domain. Truthmaker theory is not exclusive territory for realists: anti-realist views are also best understood in terms of how they understand truthmakers and truthmaking. In particular, I explore the possibility of projectivist truthmaking, and show how it makes sense of quasi-realism. In addition to critically examining some extant accounts of the (...) relationship between realism and truthmaking, I offer an account that best captures the nature of the various realism debates. (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.

Totality states of affairs (Russell's 'general facts') are defended against Martin's criticisms. Although higher-order, they are not 'abstract in Quine's sense. If space-time is the whole of being, and if it can be seen as a vast conjunction of states of affairs, then the state of affairs that this is the totality of lower-order states of affairs is not additional to, but completes, space-times. If totality states of affairs are admitted, then there seems no need for any further negative states (...) of affairs additional to totality states of affairs. (shrink)

Armstrong famously argued in favour of introducing totality facts in our ontology. Contrary to fully negative (absence) facts, totality facts yield a theory of “moderate” or “partial” negativity, which allegedly provides an elegant solution to the truthmaking problem of negative claims and, at the same time, avoids postulating (many) first-order absences. Friends of totality facts argue that partial negativity is (i) tolerable vis-à-vis the Eleatic principle qua mark of the real, and (ii) achieves a significant advantage in terms of ontological (...) parsimony. But are totality facts, which are partially negative, really more ontologically acceptable than fully negative facts? In this paper, we argue that, comparatively, the case for totality facts is weaker than commonly assumed and that, ultimately, the answer is negative. (shrink)

_ Source: _Volume 95, Issue 3, pp 368 - 413 Frege famously maintained that concepts are not objects. A key argument of Frege’s for this view is, in outline, as follows: if we are to account for the unity of thought, concepts must be deemed _unsaturated_; since objects are, by contrast, saturated entities, concepts cannot be objects. The author investigates what can be made of this argument and, in particular, of the unsaturated/saturated distinction it invokes. Systematically exploring a range of (...) reconstructions suggested by Frege’s writings, and drawing on contemporary work, the author illustrates that no plausible reconstruction is forthcoming. In essence, it is altogether unclear how to simultaneously substantiate, on the one hand, the claim that unsaturated entities must be recognized in order to account for unity and, on the other, the claim that unsaturatedness is incompatible with objecthood.

Philosophy and Literature is an internationally renowned refereed journal founded by Denis Dutton at the University of Canterbury, Christchurch. It is now published by the Johns Hopkins University Press. Since its inception in 1976, Philosophy and Literature has been concerned with the relation between literary and philosophical studies, publishing articles on the philosophical interpretation of literature as well as the literary treatment of philosophy. Philosophy and Literature has sometimes been regarded as iconoclastic, in the sense that it repudiates academic pretensions, (...) insidious jargon and institutional vogue. Dutton, who remains the editor, still writes a regular column. A distinctive feature of Philosophy and Literature was the annual Bad Writing Contest, held from 1995–98, which sought to identify (and publish) the ‘most stylistically lamentable passages’ of academic prose, often to great amusement.

Suppose nothing exists. Then it is true that nothing exists. What makes that true? Nothing! So it seems that if nothing existed, then the principle that every truth is made true by something (the truthmaker principle) would be false. So if it is possible that nothing exists, a claim often called 'metaphysical nihilism', then the truthmaker principle is not necessary. This paper explores various ways to resolve this conflict without restricting metaphysical nihilism in such a way that it would become (...) trivial and uninteresting. (shrink)

In the philosophy of perception, typically, everything is illuminated. Discussions of perceptual experience primarily focus on subjects situated in illuminated environs. Rarely do we see treatment of putative perceptual experience involving darkness. In this paper, I will carefully canvas and characterize the nature of experiences of darkness, marking a substantive distinction between two such kinds of experiences. Crucially, I give an account of the distinctive phenomenology of experiences of darkness, and show that neither of the two broad kinds of experiences (...) of darkness requires, as Roy Sorensen has recently suggested, the reification of unfamiliar entities to serve as objects of perceptual awareness. I will also offer potential candidates for the proper representational contents of experiences of darkness. This exploration not only reveals that such experiences pose no threat to a view like representationalism, but also demonstrates how experiences of darkness can be given their rightful place in a naturalistic theory of perceptual awareness. Atlast, darkness will be brought out from the shadows.

The present paper addresses Molnar’s problem :72–86, 2000): that of finding positive truthmakers for negative truths. The proposed solution, called, is to hold truth and falsity to be primitive and positive features of propositions and to take every literal negative truth to be made true by the falsity of the atomic proposition that it embeds. The solution is shown to be compatible with Maximalism, Necessitarianism and with the Entailment Thesis, as well as with most if not all possible variants of (...) truthmaking theory. Other advantages of are noted: it doesn’t require the inclusion of exotic objects in one’s ontology; it doesn’t require any revision of one’s logic or of one’s theory of modality. The solution also allows one to eschew negative facts, tropes and properties while providing a definition of negativity for certain literal propositions. The paper ends by rebutting several objections that may be levelled against. (shrink)

Can we really perceive absences, i.e., missing things? Sartre tells us that when he arrived late for his appointment at the café, he saw the absence of his friend Pierre. Is that really what he saw? Where was it, exactly? Why didn’t Sartre see the absence of other people who were not there? Why did other people who were there not see the absence of Pierre? The perception of absences gives rise to a host of conundrums and is constantly on (...) the verge of conceptual confusion. Here I focus on the need to be clear about four sorts of distinctions: (i) the difference between perceiving an absence and perceiving something that is absent; (ii) the difference between perceiving an absence and an absence of perceiving; (iii) the difference between perceiving an absence and perceiving something as an absence; and (iv) the difference between perceiving an absence and perceiving that something is absent.

We can hear silence because silence, an absence of sound, causes our hearing of it. Advocating this position, Roy Sorensen puts to use his own theory of the direct perception of absences. Sorensen’s theory, which relies on two theories of perception, certainly has its appeal. However, it also has its problematic aspects. On my reading, a weak point of his theory is that it does not provide a criterion for the identification of what exactly we hear. By elaborating this objection (...) in detail, I intend to demonstrate that Sorensen’s theory does not concern direct perception, and does not show that silence is causally efficient. Therefore, it fails to show that silence is the genuine negative object of hearing. I conclude by giving two further reasons for why the ontology that underpins Sorensen’s theory should not be endorsed. (shrink)

Truths depend upon what there is. So say many. A significant subset of that group say more; they say that the best way—perhaps the only way—to make sense of the claim that truth depends upon what there is, is to adopt a form of truth-maker theory. Truth-maker theorists claim that truths require ground; what’s true must depend upon what there is. Typically, truth-maker theory isn’t seen as a theory about the nature of truth. Rather, it’s seen as a theory about (...) what truths must do. Truths must depend. Relatedly, the claim that truths require ‘truth-makers’, that is, some putative ontological grounds, is used as a methodological tool in metaphysics. Put somewhat crudely, fix on what truths there are and locate the truth-makers—if necessary, add to your ontology until you satisfy this demand for truth-makers. Truth-making is thus at once both narrow and broad. It’s narrow insofar as it’s not a theory (it’s not a claim) about the nature of truth, and yet it’s broad insofar as it enables us to determine our ontological commitments. We take this to be a two-part orthodoxy about truth-making. We reject the orthodoxy on both counts. (shrink)

This paper argues that accepting an ordinary approach to truthmakers and rejecting something I call “the metaphysical knowledge assumption” allows us to account for inquiry in terms of truthmaking. §1 introduces inquiry and the potential place of truthmakers in inquiry. §2 presents the relevant ordinary notion of truthmakers. §3 presents and motivates MKA. This assumption, I argue, makes a truthmaker-focused account of inquiry whose objects are not the fundamental nature of things impossible and thus should be rejected. The ordinary picture, (...) which understands truthmakers not exclusively in terms of the objects of fundamental reality or of semantics, but in terms of the relevant, intentional objects of inquiry, gives us an attractive, general, truthmaker-based view of inquiry.

A central problem for any truthmaker theory is the problem of negative truths. In this paper, I develop a novel, piecemeal strategy for solving this problem. The strategy puts central focus on a truth-relevant notion of aboutness within a metaphysically modest version of truthmaker theory and uses key conceptual tools gained by taking a deeper look at the best attempts to solve the problem of intentionality. I begin this task by critically discussing past proposed solutions to P-NEG in light of (...) Russell’s debate with Demos. This reveals a central difficulty with addressing the problem, specifically that one cannot be committed to incompatibility facts in one’s account of negation and of the truth of negative truths. I then present an aboutness-based version of truthmaker theory. Utilising what I call the strict and full account of aboutness, I extract aboutness-based theories of truth and falsity. I use this machinery to present a promising new strategy for solving P-NEG which does not have the problems of alternative approaches. Finally, I present and respond to some potential objections.

This bulletin contains a summary of the main topics of discussion in truthmaker theory, namely: the definition of truthmakers, problems with Truthmaker Necessitarianism and Truthmaker Maximalism, the ontological burden of truthmakers and the recalcitrant topic of truthmakers for negative truths.

Abstract: In this paper I offer an account of a particular variety of perception of absence, namely, visual perception of empty space. In so doing, I aim to make explicit the role that seeing empty space has, implicitly, in Mike Martin's account of the visual field. I suggest we should make sense of the claim that vision has a field—in Martin's sense—in terms of our being aware of its limitations or boundaries. I argue that the limits of the visual field (...) are our own sensory limitations, and that we are aware of them as such. Seeing empty space, I argue, involves a structural feature of experience that constitutes our awareness of our visual sensory limitations, and thus, in virtue of which vision has a field. (shrink)

This essay is a reflection on the idea of truth-making and its applications. I respond to a critique of my 1986 paper on truth-making and discuss some key principles at play in the Truth-maker Program as it has emerged over the past 25 years, paying special attention to negative and general truths. I maintain my opposition to negative and general facts, but give an improved account of how to do without them. In the end, I accept Truth-maker Maximalism and a (...) weakened form of Truth-maker Necessitarianism, reject the assumption that truth-makers must be entities, and urge that the idea of a truth-maker be broadened and loosened so that it applies to anti-realistic as well as realistic truths.

The development of a compositional model shows the incoherence of such notions as levels of being and both bottom-up and top-down causality. The mathematization of nature through the partial considerations of physics qua quantities is seen to lead to Pythagoreanism, if what is not included in the partial consideration is denied. An ontology of only probabilities, if not Pythagoreanism, is equivalent to a world of primitive dispositionalities. Problems are found with each. There is a need for properties as well as (...) quantities and these properties must be qualitative as well as dispositional. So there is a need for physical qualia (qualities) for the depiction of the intrinsic character of the finest interstices of nature. (shrink)

I ask whether figure-ground structure can be realized in touch, and, if so, how. Drawing on the taxonomy of touch sketched in Katz's 1925 The World of Touch, I argue that the form of touch that is relevant to such consideration is a species of immersed touch. I consider whether we can feel the space we are immersed in and, more specifically, the empty space against which the surfaces of objects, as I shall urge, “stand out.” Harnessing M. G. F. (...) Martin's account of bodily awareness and touch, I defend a positive thesis, pace Graham Nerlich on whose The Shape of Space I otherwise rely, both to defend the supposition that empty space can in principle be felt and to argue that touching empty space is not a mere species of absence perception. Along the way, I defuse a causal worry that might be thought to arise in the case of touching empty space. (shrink)

Truthmaker theorists claim that for every truth, there is something in virtue of which it is true—or, more cautiously, that for every truth in some specified class of truths, there is something in virtue of which it is true. I argue that it is hard to see how the thought that truth is grounded in reality lends any support to truthmaker theory.

Many years ago, C.B. Martin drew our attention to the possibility of ‘finkish’ dispositions: dispositions which, if put to the test would not be manifested, but rather would disappear. Thus if x if finkishly disposed to give response r to stimulus s, it is not so that if x were subjected to stimulus r, x would give response z; so finkish dispositions afford a counter‐example to the simplest conditional analysis of dispositions. Martin went on to suggest that finkish dispositions required (...) a theory of primitive causal powers; there, I think, he was mistaken. All that they require is an improved conditional analysis, and this improved analysis can be built upon whatever treatments of properties and of laws we may favour on other grounds. (shrink)

In this paper, I make a contribution to a naturalistically-minded theory of truthmakers by proposing a solution to the nasty problem of truthmakers for negative truths. After formulating the difficulty, I consider and reject a number of solutions to the problem, including Armstrong's states of affairs of totality, incompatibility accounts, and JC Beall 's polarity view. I then defend the position that absences of truthmakers are real and are responsible for making negative truths true. According to the positive account of (...) absences I offer, absences of contingent states of affairs are causally relevant mind-independent features of the physical world, located within space and time, and capable of being discovered by scientific inquiry. Recognition of the reality of absences strengthens truthmaker theory as a naturalistic metaphysics, as truth and falsity of each and every contingent proposition finds an ontological grounding in some region of the physical universe. (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)

According to truthmaker theory, particular truths are true in virtue of the existence of particular entities. Truthmaker maximalism holds that this is so for all truths. Negative existential and other ‘negative’ truths threaten the position. Despite this, maximalism is an appealing thesis for truthmaker theorists. This motivates interest in parsimonious maximalist theories, which do not posit extra entities for truthmaker duty. Such theories have been offered by David Lewis and Gideon Rosen, Ross Cameron, and Jonathan Schaffer. But these theories cannot (...) be sustained, I’ll argue, and hence maximalism comes with a serious ontological cost. Neither Armstrong’s invocation of totality facts nor the Martin-Kukso line on absences can meet this cost satisfactorily. I’ll claim that negative facts are the best (and perhaps only) way out of the problem for the truthmaker maximalist. (shrink)

Each truth has a truthmaker: an entity in virtue of whose existence that truth is true. So say truthmaker maximalists. Arguments for maximalism are hard to find, whereas those against are legion. Most accept that maximalism comes at a significant cost, which many judge to be too high. The scales would seem to be balanced against maximalism. Yet, as I show here, maximalism can be derived from an acceptable premise which many will pre-theoretically accept.

Appeals to dispositionality in explanations of phenomena in metaphysics and the philosophy of mind, require that we first agree on what we are talking about. I sketch an account of what dispositionality might be. That account will place me at odds with most current conceptions of dispositionality. My aim is not to establish a weighty ontological thesis, however, but to move the discussion ahead in two respects. First, I want to call attention to the extent to which assumptions philosophers have (...) made about dispositionality are far from innocent. The assumptions incorporate substantive theses that, by constraining the space of acceptable answers to particular philosophical questions, have inhibited the search for answers to those questions. Second, and more positively, I hope to open up the space of possibilities by offering an alternative way of conceiving dispositionality developed by C. B. Martin. (shrink)

Humans typically display hindsight bias. They are more confident that the evidence available beforehand made some outcome probable when they know the outcome occurred than when they don't. There is broad consensus that hindsight bias is irrational, but this consensus is wrong. Hindsight bias is generally rationally permissible and sometimes rationally required. The fact that a given outcome occurred provides both evidence about what the total evidence available ex ante was, and also evidence about what that evidence supports. Even if (...) you in fact evaluate the ex ante evidence correctly, you should not be certain of this. Then, learning the outcome provides evidence that if you erred, you are more likely to have erred low rather than high in estimating the degree to which the ex ante evidence supported the hypothesis that that outcome would occur.

This paper identifies an overdetermination problem faced by the non-reductive dispositional property account of disposition ascriptions. Two possible responses to the problem are evaluated and both are shown to have serious drawbacks. Finally it is noted that the traditional conditional analysis of disposition ascriptions escapes the original difficulty.

This paper introduces a new approach to the theory of truthmaking. According to this approach, there are multiple forms of truthmaking. Here, I characterize and motivate a specific version of this approach, which I call a ‘Pluralist Theory of Truthmaking.’ It is suggested that truthmaking is a plural, variegated phenomenon wherein different kinds of truths, e.g., positive truths, negative truths, counterfactual truths, etc., are made true in different ways. While the paper only aims to lay the groundwork for a Pluralist (...) Theory of Truthmaking, I show how the theory can be applied to positive and negative truths. The upshot of this application is that truthmaking pluralism allows us to provide negative truths with ‘non-suspicious’ truthmakers. Finally, it is argued that Truthmaker Maximalists would do well to endorse truthmaking pluralism, as it offers a new strategy for upholding Maximalism while diminishing controversial ontological commitments. (shrink)

This paper defends a new version of truthmaker non-maximalism. The central feature of the view is the notion of a default truth-value. I offer a novel explanation for default truth-values and use it to motivate a general approach to the relation between truth-value and ontology, which I call truth-value-maker theory. According to this view, some propositions are false unless made true, whereas others are true unless made false. A consequence of the theory is that negative existential truths need no truthmakers (...) and that positive existential falsehoods need no falsemakers. (shrink)

Identifying plausible truthmakers for negative truths has been a serious and perennial problem for truthmaker theory. I argue here that negative truths are indeed made true but not in the way that positive truths are. I rely on a distinction between “existence-independence” and “variation-independence” drawn by Hoffman and Horvath to characterize the unique form of dependence negative truths exhibit on reality. The notion of variation-independence is then used to motivate a principle of truthmaking for contingent negative truths.

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