Dynamic theories of time typically commit to the claim that “time passes”. In this paper I develop a version of the ‘no alternate possibilities’ argument in order to show that time does not pass, but that this is no threat to dynamic theories of time.

Ross Cameron proposes to reconcile presentism and truth-maker theory by invoking temporal distributional properties, instantiated by present entities, as the truth-makers for truths about the past. This chapter argues that Cameron's proposal fails because objects can change which temporal distributional properties they instantiate and this entails that the truth-values of truths about the past can change in an objectionable way.

We aim to introduce presentism and to consider the question that presentism is supposed to answer. That is, if “only present objects exist” (or some appropriate precisification of the slogan) is the answer to a philosophical question, then (i) what is the question? And (ii) is it the right question to ask? We suggest that the question presentists are answering is not a good one to ask. We aim to articulate a question that presentists, or the heirs of presentism, should (...) try to answer. In pursuing these aims, we provide the reader with a sense of how we have reached the current position in the literature, as well as how we might move it along. (shrink)

Presentism is the view that only present things exist. So understood, presentism is primarily an ontological doctrine; it’s a view about what exists, absolutely and unrestrictedly. The view is the subject of extensive discussion in the literature on time and change, with much of it focused on the problems that presentism allegedly faces. Thus, most of the literature that frames the development of presentism has grown up either in formulating objections to the view (e.g., Sider 2001: 11–52), or in response (...) to such objections (e.g., Bigelow 1996; Markosian 2004), with exceptions to this largely coming via the ways in which presentism is motivated. This entry mirrors the structure of that literature, for the most part. Here’s the plan for what follows. We begin with a more detailed sketch of presentism, unpacking its commitments and motivations. Then, we move to consider several concerns raised for presentists. We use these to illustrate the breadth and severity of the challenges that presentism faces, as well as the range of different versions of presentism developed to help meet these challenges. (shrink)

Presentists, who believe that only present objects exist, face a problem concerning truths about the past. Presentists should (but cannot) locate truth-makers for truths about the past. What can presentists say in response? We identify two rival factions ‘upstanding’ and ‘nefarious’ presentists. Upstanding presentists aim to meet the challenge, positing presently existing truth-makers for truths about the past; nefarious presentists aim to shirk their responsibilities, using the language of truth-maker theory but without paying any ontological price. We argue that presentists (...) should be nefarious presentists. (shrink)

1. IntroductionA popular view in metaphysics is that which propositions are true depends upon how the world is . In more evocative language, truth requires ground. This thought then gets used to do some serious work. As Sider has it, ‘[t]he point of … the principle that truth supervenes on being is to rule out dubious ontologies’. Here, I argue that ‘dubious’ ontologies are theoretically virtuous.

Here, I defend the view that there is no sensible way to pin a truth-maker objection on presentism. First, I suggest that if we adopt truth-maker maximalism then the presentist can requisition appropriate ontological resources with impunity. Second, if we deny maximalism, then the presentist can sensibly restrict the truth-maker principle in order to avoid the demand for truth-makers for talk about the non-present.

In this paper I argue in favour of a new definition of presentism that I call ‘existence presentism’ (EP). Typically, presentism is defined as the thesis that ‘only present objects exist’, or ‘nothing exists that is non-present’.1 I assume these statements to be equivalent. I call these statements of presentism ‘conventional presentism’ (CP). First, in §2, I rehearse arguments due to Ulrich Meyer that purport to show that presentism is not adequately defined as CP. In §§2.1–2.4 I show that considerations (...) of the sort raised by Meyer infect attempts to define presentism, due to Thomas Crisp, Tom Stoneham, and Theodore Sider. Thus the first half of the paper is constituted by a negative project that looks to show how extant definitions of presentism fail. In the second half of the paper, I continue in the negative theme in §3, before laying out EP and demonstrating that it solves the problems faced by CP and offering explanations of how to make sense of certain key notions that lie at the heart of EP. I conclude that EP is preferable to CP. (shrink)

How do we explain the truth of true propositions? Truthmaker theory is the branch of metaphysics that explores the relationships between what is true and what exists. It plays an important role in contemporary debates about the nature of metaphysics and metaphysical enquiry. -/- In this book Jonathan Tallant argues, controversially, that we should reject truthmaker theory. In its place he argues for an 'explanationist' approach. Drawing on a deflationary theory of truth he shows that it allows us (...) to explain the truth of true propositions and respond to recent arguments that purport to show otherwise. He augments this with a distinction between internally and externally quantified claims: externally quantified claims are claims that quantify over elements of our ontology that play an indispensable explanatory role; internally quantified claims do not. He deploys this union of deflationism and a distinction between kinds of quantification to pursue metaphysical inquiry, sketching the implications for a number of first-order debates, including those in the philosophy of time, modality and mathematics, and also shows how this explanationist model can be used to solve the key problems that afflicted truthmaker theory. -/- Truth and the World is an important contribution to debates about truth and truthmaker theory as well as metametaphysics, the metaphysics of time and the metaphysics of mathematics, and is essential reading for students and scholars engaged in the study of these topics.

Recently, some have attempted to reformulate debates in first-order metaphysics, particularly in the metaphysics of time and modality, for reasons due to Williamson. In this paper, we focus on the ways in which the likes of Cameron, Correia and Rosenkranz, Deasy, Ingram, Tallant, Viebahn, inter alia, have initiated and responded to attempts to capture the core of presentism using a formal, logical machinery. We argue that such attempts are doomed to fail because there is no theoretical core to presentism. (...) There is no single view or family of views that is presentism. (shrink)

I argue that mereological nihilism fails because it cannot answer the special arrangement question: when is it true that the xs are arranged F-wise? I suggest that the answers given in the literature fail and that the obvious responses that could be made look to undermine the motivations for adopting nihilism in the first place.

ABSTRACT Our aim in this article is to offer a new justification for preferring theories that are more quantitatively parsimonious than their rivals. We discuss cases where it seems clear that those involved opted for more quantitatively parsimonious theories. We extend previous work on quantitative parsimony by offering an independent probabilistic justification for preferring the more quantitatively parsimonious theories in particular episodes of theory choice. Our strategy allows us to avoid worries that other considerations, such as pragmatic factors of computational (...) tractability and so on, could be the driving ones in the historical cases under consideration. _1_ Introduction _2_ Three Desiderata _2.1_ Limiting _2.2_ Robustness _2.3_ Breadth _2.3.1_ A limited success for Baker _2.3.2_ Rejecting Baker’s analysis _2.4_ The proposal _3_ Probabilistically Additive Hypotheses and a Bayesian Account: The Limpid Rationale Relativized and Reconsidered _3.1_ Neutrinos and beta decay _3.2_ Avogadro’s hypothesis _3.3_ Postulation of Neptune _4_ Conclusion.

Next SectionIn this article I offer a new version of presentism and argue that this new version of presentism is not a species of the A-theory. Along the way, I argue that Rasmussen’s recent attempt to articulate a version of presentism that is not also a version of the A-theory does not succeed.

According to some views of reality, some objects are fundamental and other objects depend for their existence upon these fundamental objects. In this article, I argue that we have reason to reject these views.

In this paper I look to develop a defence of “presentist temporal passage” that renders presentism immune from recent arguments due to Eric Olson. During the course of the paper, I also offer comment on a recent reply to Olson’s argument due to Ian Phillips. I argue that it is not clear that Phillips’ arguments succeed.

In this paper, we defend Lucretian Presentism. Although the view faces many objections and has proven unpopular with presentists, we rehabilitate Lucretianism and argue that none of the objections stick.

Priority Monism, as defined by Jonathan Schaffer, has a number of components. It is the view that: the cosmos exists; the cosmos is a maximal actual concrete object, of which all actual concrete objects are parts; the cosmos is basic—there is no object upon which the cosmos depends, ontologically; ontological dependence is a primitive and unanalysable relation. In a recent attack, Lowe has offered a series of arguments to show that Monism fails. He offers up four tranches of argument, (...) with different focuses. These focal points are: being a concrete object; aggregation and dependence; analyses of ontological dependence; Schaffer’s no-overlap principle. These are all technical notions, but each figures at the heart of a cluster of arguments that Lowe puts forward. To respond, I work through each tranche of argument in turn. Before that, in the first section, I offer a cursory statement of Monism, as Schaffer presents it in his 2010 paper, Monism: The Priority of the Whole. I then respond to each of Lowe’s criticisms in turn, deploying material from Schaffer’s 2009 paper Spacetime: the One Substance, as well as various pieces of conceptual machinery from Lowe’s own works to deflect Lowe’s attacks. In the process of defending Monism from Lowe, I end up offering some subtle refinements to Schaffer’s view and explain how the resulting ‘hybrid’ view fares in the wider dialectic. (shrink)

My central thesis is that presentism is incompatible with all of the main theories of persistence: endurance, exdurance and perdurance.

In this paper I argue that presentism —the view that only present objects exist—can be motivated, at least to some degree, by virtue of the fact that it is more quantitatively parsimonious than rival views.

Presentists face a familiar problem. If only present objects exist, then what 'makes true' our true claims about the past? According to Ross Cameron, the 'truth-makers' for past and future tensed propositions are presently instantiated Temporal Distributional Properties. We present an argument against Cameron's view. There are two ways that we might understand the term 'distribute' as it appears. On one reading, the resulting properties are not up to the task of playing the truth-maker role; on the other, the properties (...) are incompatible with presentism. (shrink)

Here I examine some recent attempts to provide a new way of thinking about the philosophy of time that question the central role of ‘presentness’ within the definition of presentism. The central concern raised by these critics turns on the intelligibility and theoretical usefulness of the term ‘is present’. My overarching aim is to at least challenge such concerns. I begin with arguments due to Deasy. Deasy develops a view that he calls ‘transientism’ and that he takes to be a (...) well-motivated version of presentism. I show that both this way of thinking about presentism and the argument supposedly motivating it all fail. I then move to an argument due to Correia and Rosenkrantz. Correia and Rosenkrantz purport to show that presentism can be salvaged without making recourse to the term ‘is present’. I demonstrate that their arguments fail. I then move on to a view, proposed and defended by Merricks, Tallant, and Zimmerman, and show that it has the wherewithal to meet the challenges raised by Williamson who, as noted above, raises genuine concerns about our capacity to define presentism. (shrink)

My claim in this article is that, contra what I take to be the orthodoxy in the wider literature, we do trust inanimate objects – per the example in the title, there are cases where people really do trust a ladder (to hold their weight, for instance), and, perhaps most importantly, that this poses a challenge to that orthodoxy. My argument consists of four parts. In Section 2 I introduce an alleged distinction between trust as mere reliance and trust as (...) a rich, morally loaded notion. In the course of doing so, I briefly sketch some models of trust. This will help us to get a handle on how some of the mainstream models of trust preclude or ignore the trusting of inanimate objects. In Section 3 I introduce cases designed to show that we have reason to think that we do trust inanimate objects. In Section 4 I consider an objection, and in Section 5 I discuss some consequences of this finding, before concluding in Section 6. (shrink)

The purpose of this paper is two fold: first, I look to show Oaklander’s theory of time to be false. Second, I show that the only way to salvage the B-theory is via the adopting of the causal theory of time, and allying this to Oaklander’s claim that tense is to be eliminated. I then raise some concerns with the causal theory of time. My conclusion is that, if one adopts eternalism, the unreality of time looks a better option than (...) the B-theory. (shrink)

It is, I think, possible to generate a variation of McTaggart’s (Mind 17:457–474, 1908 ) paradox that infects all extant versions of presentism. This is not to say that presentism is doomed to failure. There may be ways to modify presentism and I can’t anticipate all such modifications, here. For the purposes of the paper I’ll understand ‘presentism’ to be the view that for all x , x is present (cf. Crisp ( 2004 : 18)). It seems only right that, (...) at a conference devoted to McTaggart’s work on time, we continue to pursue new ways in which his now infamous arguments remain relevant to us today. (shrink)

This paper is an exploration of the role of intuition in physics. The ways in which intuition is appealed to in physics are not well understood. To the best of my knowledge, there is no analysis of the different contexts in which we might appeal to intuition in physics, nor is there any analysis of the different potential uses to which intuition might be put. In this paper I look to provide data that goes some way to giving a sense (...) of the different contexts in which intuition is appealed to in physics. As I note in the conclusion, there is still much work to be done but I hope that the work here provides us with a first step in the journey to properly understand the use to which intuitions are put in physics and science more generally.

Philosophical enquiry stands to benefit from the inclusion of methods from the digital humanities to study language use. Empirical studies using the methods of the digital humanities have the potential to contribute to both conceptual analysis and intuition-based enquiry, two important approaches in contemporary philosophy. Empirical studies using the methods of the digital humanities can also provide valuable metaphilosophical insights into the nature of philosophical methods themselves. The use of methods from the digital humanities in philosophy should be expected to (...) follow a similar trajectory to another attempt to introduce empirical methods in philosophy. Experimental philosophers use empirical methods from the cognitive sciences to bear on philosophical questions. At first, we should expect the main contribution of methods from the digital humanities in philosophy to be at the metaphilosophical level. Then, given the right impetus and support, we are optimistic that methods from the digital humanities can make important and sustained contributions to first-order philosophical enquiry. This chapter gives two case studies of recent studies in which methods from the digital humanities are used to address metaphilosophical questions about the use of the word ‘intuition’ and the methods of philosophy and physics. It gives three examples of contemporary first-order philosophical debates to which methods fromthe digital humanities could make an important contribution in epistemology, metaphysics and philosophy of language. The chapter discusses some methodological challenges and limitations which are of particular importance when considering the application of methods from the digital humanities in philosophy, including concerns about the demographic representativeness of widely available corpora.

This paper is an attempt to answer the question, ‘could there be causation in a timeless world?’ My conclusion: tentatively, yes. The paper and argument have three parts. Part one introduces salient issues and spells out the importance of this line of investigation. Section two of the paper reviews recent arguments due to Baron and Miller, who argue in favour of the possibility of causation in a timeless world, and looks to reject their arguments developed there. Section three is a (...) response to a response. In their, Baron and Miller also argue that an argument in favour of the possibility of causation at timeless worlds, that I put forward, is an argument that fails. In section three, my response to Baron and Miller is that their argument against me succeeds, but that there is a nearby argument that we can appeal to in order to demonstrate the possibility of causation at timeless worlds.

A dominant claim in the philosophical literature on trust is that we should stop thinking in terms of group trustworthiness or appropriate trust in groups. In this paper, we push back against this claim by arguing that philosophical work on trust would benefit from being brought into closer contact with empirical work on the nature of trust. We consider data on reactive attitudes and moral responsibility to adjudicate on different positions in the philosophical literature on trust. An implication of our (...) argument is that the distinction between different kinds of groups—mere groups versus institutional groups—deserves more attention than is currently recognized in the philosophical literature on trust.In the first section of the paper, we draw some basic philosophical distinctions concerning the nature and kinds of trust. In section two, we present the positions taken by Hawley (2017), who argues against trust in groups, and Faulkner (2018), who argues in favor of trust in groups. In section three, we introduce some empirical data and suggest that, albeit tentatively, this looks to undermine Hawley's position and is compatible with Faulkner's approach. We thus suggest, on the basis of the evidence that we have available, that we have reasons to prefer the position taken by Faulkner (2018) over that taken by Hawley (2017). We end by discussing some implications for distinctions between different kinds of groups relevant for future philosophical work on trust. (shrink)

Baker (Mind 114:223–238, 2005; Brit J Philos Sci 60:611–633, 2009) has recently defended what he calls the “enhanced” version of the indispensability argument for mathematical Platonism. In this paper I demonstrate that the nominalist can respond to Baker’s argument. First, I outline Baker’s argument in more detail before providing a nominalistically acceptable paraphrase of prime-number talk. Second, I argue that, for the nominalist, mathematical language is used to express physical facts about the world. In endorsing this line I follow moves (...) made by Saatsi (Brit J Philos Sci 62(1):143–154, 2011). But, unlike Saatsi, I go on to argue that the nominalist requires a paraphrase of prime-number talk, for otherwise we lack an account of what that ‘physical fact’ is in the case of mathematics that seemingly makes reference to prime numbers.

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)

In two recent papers Button (Analysis 66:130–135, 2006, Analysis 67:325–332, 2007) has developed a particular view of time that he calls no-futurism. He defends his no-futurism against a sceptical problem that has been raised (by e.g. Bourne in Aust J Phil 80:359–371, 2002) for a similar growing block view—that of Tooley (Time, tense, and causation, Clarendon Press, Oxford, 1997). If Button is right, then we have an important third option available to us: a half-way house between presentism and eternalism. If, (...) on the other hand, the criticism of Tooley-style Growing-Block views holds, then we are left with just presentism and eternalism. In this paper I show that Button’s defence fails. (shrink)

The aim of this paper is to motivate and then defend a restricted version of the truth-maker theory. In defending such a theory I hope to do away with the perceived need for ‘negative existents’ such as totality facts and the like.

The New A-theory of Time is the view, to be elaborated and defended in this article, that many times exist, and that time is real in virtue of every moment in time bearing each of the so-called A-properties: past, present and future. I argue that TNAT is at least as theoretically virtuous as mainstream views in the philosophy of time and may have some claim to being our best theory of time. I show that the properties ‘past’, ‘present’ and ‘future’ (...) can be understood as compatible intrinsic properties. Having demonstrated that this account of the A-properties is coherent, I go on to demonstrate how TNAT can give us an account of passage, change and the truth-conditions for temporal sentences. In the final section of the article, I develop a tentative argument in favour of TNAT, though concede that we have to settle for the result that TNAT is on a par with our other theories of time. In the remainder of this opening section, my aim is to situate the current proposal as a direct response to Mc.. (shrink)

Within the philosophy of time there has been a growing interest in positions that deny the reality of time. Those positions, whether motivated by arguments from physics or metaphysics, have a shared conclusion: time is not real. What has not been made wholly clear, however, is exactly what it entails to deny the reality of time. Time is unreal, sure. But what does that mean? There has been only one sustained attempt to spell out exactly what it would mean to (...) endorse a temporal error theory; a theory that denies the reality of time—Baron & Miller’s ‘What is temporal error theory?’. Despite the fact that their paper makes significant strides in spelling out what would be required of a temporal error theory, my claim in this paper is that their position must be rejected and replaced. As well as looking to reject Baron and Miller’s position, I also look to provide that replacement. (shrink)

There is a well-developed literature on trust. Distrust, on the other hand, has gathered far less attention in the philosophical literature. A recent exception to that trend in the philosophical literature is Hawley who develops a unified account of both trust and distrust. My aim in this paper is to present arguments against her account of trust and distrust, though then to also suggest a patch.

This is a paper about trust, with a specific focus on the ways in which trust is investigated in the business literature and the commercial sector. The lens through which the topic is approached is distinctively philosophical. We use philosophical tools to demonstrate the paucity of some of the accounts of trust that are given in the business and management literature, as well as the empirically informed literature that has flowed from them. We close with a discussion of some work (...) on trust drawn from the commercial sector that would, as we shall demonstrate, benefit from a clearer understanding of the nature of trust. We take this to be important. Trust is a key moral and ethical component of transactional relationships. Without a clear understanding of the notion, we will be missing a central concept in our attempts to understand the commercial world that we inhabit. The paper proceeds in four parts. In the first part of the paper we introduce some reasonably standard philosophical distinctions between different kinds of trust, as well as saying a little more about our methods. In the second, we demonstrate that a reasonably widely held account of trust in the business and management literature fails to capture the nuance reflected by the philosophical literature. On the basis of this, in the third section, we suggest that various pieces of empirical work require reassessment. In the final part of the paper we explore some non-academic discussions of trust drawn from the commercial sector arguing that, there too, we require a more precise understanding of trust. In short, though, our overarching argument is simply this: if we can give a more precise analysis of trust, it follows that both our empirical research and current commercial activity can be improved.

According to B-theorists, B-relations (‘earlier than’ and ‘later than’, see, e.g. Oaklander 2004: 24–25) constitute the reality of time. The B-relations are what distinguish our world from a timeless one. Yet our only awareness of the reality of time comes via our phenomenology of temporal passage. Why is this noteworthy? Our temporal phenomenology is mind-dependent and reflects no feature of reality. Epistemic access to the reality of time is, in fact, simply epistemic access to our own inner phenomenology. It doesn’t (...) reflect the way reality is. Hence, we have no understanding of what ‘B-time’ is. (shrink)

Ladyman and Ross do not think that contemporary metaphysics is in good standing. However, they do think that there is a version of metaphysics that can be made to work – provided we approach it using appropriate principles. My aim in this paper is to undermine some of their arguments against contemporary metaphysics as it is currently practiced.

A pretense theory of a given discourse is a theory that claims that we do not believe or assert the propositions expressed by the sentences we token (speak, write, and so on) when taking part in that discourse. Instead, according to pretense theory, we are speaking from within a pretense. According to pretense theories of mathematics, we engage with mathematics as we do a pretense. We do not use mathematical language to make claims that express propositions and, thus, we do (...) not use mathematical discourse to make claims that are either true or false. In this paper I make use of recent findings from cognitive neuroscience and developmental science to suggest that pretense theories of mathematics fail. 1 Introduction 2 The Autism Objection 2.1 Autism and pretense 2.2 Autistic engagement with mathematics 2.2.1 Cortical folding 2.2.2 The language of mathematics 3 The Onset of the Number Sense and the Recognition of Pretense 3.1 A difference in neurology 3.2 Young and no numbers 3.2.1 When and where is the difference? 3.2.2 Damaged HIPS without impairment to engagement with fiction 4 Concluding Remarks.

Some theories in the philosophy of time combine a commitment to the existence of non-present regions of spacetime with the view that there is a perspective-independent present time. We call such theories 4D A-theories. There is a well-known objection to 4D A-theories, as follows: 4D A-theories entail that the vast majority of subjects across time believe falsely that they are present. But if the vast majority of subjects across time believe falsely that they are present, we do not know that (...) we are present. We call this the Epistemic Objection to 4D A-theories. In this paper we do two things: first, we describe and assess a number of different versions of the Epistemic Objection. We argue that there is only one version of the objection—the version due to Russell that we call the Safety Argument—that does not rely on implausible epistemic principles which entail radical scepticism. Second, we raise objections to the main strategies adopted by 4D A-theorists in response to the Safety Argument. We conclude that the Epistemic Objection—in the form of the Safety Argument—remains a threat to 4D A-theories. (shrink)

This is the definitive companion to the study of metaphysics. It provides students with an accessible, comprehensive and philosophically rigorous introduction to all the key concepts, issues and debates. Ideal for use on undergraduate courses, the structure and content of this textbook closely reflect the way metaphysics is studied. Thematically structured, the text introduces all the various philosophical problems addressed by metaphysics through the idea of truth-making, a useful lens through which the topic is clearly and concisely explicated. With a (...) particular focus on method in contemporary metaphysics, the book examines a variety of metaphysical topics, including the nature of properties, time, causation and objects. The book offers lucid and incisive coverage of the field of metaphysics, its key concepts and current debates. Jonathan Tallant's cogent and thorough analysis is supplemented by student-friendly features, including chapter summaries, study questions and a comprehensive guide to further reading. Each chapter includes a series of specially designed mind-maps to help students visualise the logical space being explored and how the arguments push in different directions. (shrink)

This paper introduces a new kind of explanation that we describe as ‘purely theoretical’. We first present an example, E, of what we take to be a case of purely theoretical explanation. We then show that the explanation we have in mind does not fit neatly into any of the existing categories of explanation. We take this to give us prima facie motivation for thinking that purely theoretical explanation is a distinctive kind of explanation. We then argue that it can (...) earn its keep via application to two existing literatures: the literature on how we explain the truth of true negative existential propositions and the literature on how we explain the truth of true propositions about the past. We reply to some possible concerns regarding the introduction of purely theoretical explanations. We conclude that there is nothing obviously wrong with them and explore the ramifications for particular debates in metaphysics. (shrink)

Ross Cameron puts forward a novel solution to the truthmaker problem facing presentism. I claim that, by Cameron's own lights, the view is not in fact a presentist view at all, but rather requires us to endorse a form of Priority Presentism, whereby past objects are derivative and depend for their existence upon present objects. I argue that this view should be rejected.

There is a charge sometimes made in metaphysics that particular commitments are ‘hypothetical’, ‘dubious’ or ‘suspicious’. There have been two analyses given of what this consists in—due to Crisp (2007) and Cameron (2011). The aim of this paper is to reject both analyses and thereby show that there is no obvious way to press the objection against said commitments that they are ‘dubious’ and objectionable. Later in the paper I consider another account of what it might be to be ‘dubious’, (...) and argue that this too fails. I use Bigelow's (1996) Lucretian properties as a vehicle for the discussions of dubiousness that follow. As a consequence, the paper ends up offering a partial defense of Lucretianism. (shrink)

In this paper we offer a response to one argument in favour of Priority Monism, what Jonathan Schaffer calls the nomic argument for monism. We proceed in three stages. We begin by introducing Jonathan Schaffer’s Priority Monism and the nomic argument for that view. We then consider a response to the nomic argument that we presented in an earlier paper. We show that this argument suffers from a flaw. We then go on to offer a different response to (...) the nomic argument. The core idea is that the current laws of physics are not integrated in the manner that Schaffer requires to get the nomic argument for monism off the ground. (shrink)
