Thisness Presentism outlines and defends a novel version of presentism, the view that only present entities exist and what is present really changes. Presentism is a view of time that captures a real and objective difference between what is past, present, and future, and which offers a model of reality that is dynamic and mutable, rather than static and immutable. The book advances a new defence of presentism by developing a novel ontology of thisness, combining insights (...) about the nature of essence, the metaphysics of propositions, and the relationship between true propositions and the elements of reality that make them true, alongside insights about time itself. It shows how, by accepting an ontology of thisness, presentists can respond to a number of pressing challenges to presentism, including claims that presentism cannot account for true propositions about the past, and that it is inconsistent with the reality of temporal passage and the openness of the future. This is one of the only book-length defences of presentism. It will be of interest to students and scholars working on the debate about presentism in the philosophy of time, as well as those interested in the metaphysics of propositions and truth-making, more generally.

How can we talk meaningfully about the past if it does not exist to be talked about? What gives time its direction? Is time travel possible? This defence of presentism - the view that only the present exists - makes an original contribution to a fast growing and exciting debate.

We lay out the fatalist’s argument, making sure to clarify which dialectical moves are available to the libertarian. We then offer a more robust presentation of Ockhamism, responding to obvious objections and teasing out the implications of the view. At this point, we discuss presentism and eternalism in more detail. We then present our argument for the claim that the libertarian cannot take Ockham’s way out of the fatalism argument unless she rejects presentism. Finally, we consider and dispense (...) with objections to our argument. In the end, it ought to be clear that the libertarian must make a choice between Ockham’s way out and presentism. (shrink)

If _presentism_ is true, then no wholly non-present events exist. If _absence orthodoxy_ is true, then no absences exist. I discuss a well-known causal argument against presentism, and develop a very similar argument against absence orthodoxy. I argue that solutions to the argument against absence orthodoxy can be adopted by the presentist as solutions to the argument against presentism. The upshot is that if the argument against absence orthodoxy fails, then so does the argument against presentism.

Presentism is the doctrine that only the present is real. Since ordinary talk and thought are full of quantification over non-present objects, presentists are in a familiar predicament: in their unreflective moments they apparently commit themselves to far more than their ontological scruples allow. A familiar response is to begin a project of paraphrase. Truths appearing to quantify over problematic entities are shown, on analysis, to not involve quantification over those entities after all. But I think that we might (...) be better off abandoning paraphrase altogether. I suggest a project of discovering “underlying truths” rather than paraphrases. I will explore this strategy as applied to defending presentism, but my hope is that lovers of desert landscapes everywhere will herein find words of comfort. (shrink)

Presentism is the view that only present entities exist. Recently, several authors have asked the question whether presentism is able to account for cross-time relations, i.e., roughly, relations between entities existing at different times. In this paper I claim that this question is to be answered in the affirmative. To make this claim plausible, I consider four types of cross-time relation and show how each can be accommodated without difficulty within the metaphysical framework of presentism.

This paper has three main sections. The first section provides a general characterisation of presentism, eternalism and growing blockism. It presents a pair of core, defining claims that jointly capture each of these three views. This makes clear the respects in which the different views agree, and the respects in which they disagree, about the nature of time. The second section takes these characterisations and considers whether we really do have three distinct views, or whether defenders of these views (...) are somehow talking past one another when they claim to disagree. The third section looks at the key objections to each view and considers some of the replies that can be made to those objections. The paper concludes by offering some thoughts about how future research might help us resolve the debate between defenders of these three views. (shrink)

Presentism is the view that only presently existing things exist. Actualism is the view that only actually existing things exist. Although these views have much in common, the position we take with respect to one of them is not usually thought to constrain the position that we may take toward the other. In this paper I argue that this standard attitude deserves further scrutiny. In particular, I argue that the considerations that motivate one common objection to presentism—the grounding (...) objection—threaten to give rise to an analogous grounding objection to actualism. Those who are moved by grounding considerations to give up presentism should either be moved by analogous considerations to give up actualism as well or be prepared to undertake quite a bit of further work in order to defend their position. (shrink)

We argue that presentism, understood as a view about time and existence, can perspicuously be defined in opposition to all other familiar contenders without appeal to any notion of presentness or cognate notions such as concreteness. Given recent worries about the suitability of such notions to cut much metaphysical ice, this should be welcomed by presentism's defenders. We also show that, irrespective of its sparse ideology, the proposed formulation forestalls any deviant interpretation at odds with the view it (...) aims to capture. (shrink)

Three plausible views—Presentism, Truthmaking, and Independence—form an inconsistent triad. By Presentism, all being is present being. By Truthmaking, all truth supervenes on, and is explained in terms of, being. By Independence, some past truths do not supervene on, or are not explained in terms of, present being. We survey and assess some responses to this.

Abstract- Presentism And Temporal Experience Intuitively, we all believe that we experience change and the passage of time. Presentism prides itself as the most intuitive theory of time. However, a closer look at how we would experience temporality if presentism was true reveals that this is far from obvious. For if presentism was really so intuitive, then it would do justice to these intuitions. In the course of this article I examine how presentism fares when (...) combined with various leading theories of perception and temporal perception. I focused on two Central Questions. Can presentism, given theory X, account for experiences of change and duration? And can presentism, given theory X, account for experiences of time as passing? I argue that there is no possible combination which allows for an experience of time as passing. This result alone undermines the alleged intuitive advantage of presentism and with it the motivation for the view. Presentism, it remains safe to say, is not as intuitive a theory as its adherents like to portray it. (shrink)

This paper argues that recent arguments to the effect that the debate between presentism and eternalism lacks any metaphysical substance ultimately fail, although important lessons can be gleaned from them in how to formulate a non-vacuous version of presentism. It suggests that presentism can best be characterized in the context of spacetime theories. The resulting position is an ersatzist version of presentism that admits merely non-present entities as abstracta deprived of physical existence. Ersatzist presentism both (...) escapes the charges of triviality and promises to offer a route to solving the grounding problem which befalls its more traditional cousins. (shrink)

The presentist view of time is psychologically appealing. I argue that, ironically, contingent facts about the temporal properties of consciousness are very difficult to square with presentism unless some form of mind/body dualism is embraced.

Presentists believe that only present things exist. Their theories, at first glance, seem to offer many admirable features: a simple ontology, and a meaningful, objective status for key temporal phenomena, such as the present moment and the passage of time. So intuitive is this theory that, as John Bigelow puts it, presentism was “believed by everyone...until at least the nineteenth century”. Yet, in the last 200 years presentism has been beset by criticisms from both physicists and metaphysicians. One (...) of the most significant criticisms is that presentists cannot provide an acceptable system of truthmaking. If there is no past, how can there still be truths about the past? In this paper, I introduce a new theory of presentism, which addresses this problem in a novel way: by simply denying that there are any truths about the past. While prima facie an unintuitive position, I will argue that a sensible presentist philosophy of this kind can be described, so long as it is accompanied by an appropriate system of physics. I will also indicate at certain points that adopting presentism could allow us to understand fundamental physics in new, more intuitive ways. By the end of the paper, I hope to not only show that hard presentism is a defensible theory of time, but also that it could offer a number of advantages to the physicist and the philosopher alike.

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.

Presentism is, roughly, the metaphysical doctrine that maintains that whatever exists, exists in the present. The compatibility of presentism with the theories of special and general relativity was much debated in recent years. It has been argued that at least some versions of presentism are consistent with time-orientable models of general relativity. In this paper we confront the thesis of presentism with relativistic physics, in the strong gravitational limit where black holes are formed. We conclude that (...) the presentist position is at odds with the existence of black holes and other compact objects in the universe. A revision of the thesis is necessary, if it is intended to be consistent with the current scientific view of the universe. (shrink)

In “A Defense of Presentism ”, Ned Markosian addresses the problem of singular propositions about non-present objects. The proposed solution uses a paraphrasing strategy that differentiates between two kinds of meaning in declarative sentences, and also distinguishes between two truth-conditions for singular propositions. The solution, however, is unsatisfactory. I demonstrate that the both truth-conditions suffer from the same problems in spite of the examples used to support the claim that one is a proper treatment for singular propositions. Part of (...) the difficulty is in the limited expressivity of logical formalisms, a limitation not unique to the philosophy of time, but which calls for greater attention. (shrink)

Presentism is held by most to be the intuitive theory of time, due in large part to the view's supposed preservation of time's passage. In this paper, I strike a blow against presentism's intuitive pull by showing how the presentist, contrary to overwhelming popular belief, is unable to establish temporal change upon which the passage of time is based. I begin by arguing that the presentist's two central ontological commitments, the Present Thesis and the Change Thesis, are incompatible. (...) The main problem is that satisfying the Change Thesis to establish passage requires the existence of more than one moment. This conflicts with the Present Thesis that only the present moment exists. The presentist's response is to appeal to surrogates to stand proxy for the past, so as to account for the difference between what does exist and what did exist. I argue that, for this surrogate strategy to be successful, the proposed surrogates must track what actually happened. I demonstrate that there is no guarantee that t.. (shrink)

Building on my previous writings on presentism, pluralism, and “complementary science”, I develop an activist view of historiography. I begin by recognizing the inevitability of presentism. Our own purposes and perspectives do and should guide the production of our accounts of the past; like funerals, history-writing is for the living. There are different kinds of presentist history, depending on the historians’ purposes and perspectives. My particular inclination is pluralist. Science remembers its own history from a particular perspective, which (...) views the past as imperfect versions of the present; if professional historians of science shared this perspective, our work would be redundant. Instead, we can make it our task to illuminate the aspects of the past of science that scientists themselves tend to ignore and forget. History of science can also take a more productive role in the creation and improvement of scientific knowledge. Scientific progress as we know it tends to involve the shutting down of alternative paths of inquiry, resulting in a loss of potential and actual knowledge. A critical and sympathetic engagement with the past allows us to recover the lost paths, which can also suggest new paths. These points will be illustrated by a number of examples, especially from the history of chemistry and physics, including the recovery and extension of past experiments. (shrink)

This paper defends three theses: that presentism is either trivial or untenable; that the debate between tensed and tenseless theories of time is not about the status of presentism; and that there is no temporal analogue of the modal thesis of actualism.

The Triviality Argument against presentism maintains that we should reject presentism because there is no way to define the view that is not either trivially true or obviously false. We suggest that this style of argument over-emphasises purely linguistic means of representing a philosophical thesis. We argue that there is no reason to suppose that all philosophical theses must be linguistically representable, and thus that the failure to linguistically represent presentism is no big deal. It certainly shouldn’t (...) lead us to reject the view. We offer a more general moral for philosophy, and that is to look beyond purely linguistic methods of representing philosophical views and embrace a wider range of representational media. (shrink)

The distinction between presentism and eternalism is usually sought in some formula like ‘Only presently existing things exist’ or ‘Past, present, and future events are equally real’. I argue that ambiguities in the copula prevent these slogans from distinguishing significant opposed positions. I suggest in addition that one can find a series of significant distinctions if one takes spacetime structure into account. These presentisms and eternalisms are not contradictory. They are complementary elements of a complete naturalistic philosophy of (...) time. (shrink)

David Lewis sells modal realism as a package that includes an eternalist view of time. There is, of course, nothing that ties together the thesis that modality should be analyzed in terms of "concrete" possibilia with the view that non-present things exist. In this paper I develop a theory I call \emph{modal realist presentism} that is a combination of modal realism and presentism, and argue that is has compelling answers to some of the main objections to presentism, (...) including the arguments from (i) singular propositions, (ii) cross-temporal relations, and (iii) truthmaking. Toward the end, I compare modal realist presentism favorably to some similar theories, including Bigelow's modal theory of time, Williamson's theory of the ex-concrete, and Dainton's theory of many-worlds presentism.

There is an objection to divine timelessness which claims that timelessness shouldn’t be adopted since on this view evil is never “destroyed,” “vanquished,” “eradicated” or defeated. By contrast, some divine temporalists think that presentism is the key that allows evil to be destroyed/vanquished/eradicated/defeated. However, since presentism is often considered to be inconsistent with timelessness, it is thought that the presentist solution is not available for defenders of timelessness. In this paper I first show how divine timelessness is consistent (...) with a presentist view of time and then how defenders of Presentist-Timelessness can adopt the presentist solution to the removal of evil. After this, I conclude the paper by showing that it’s far from clear that the presentist solution is successful and that unless one weakens what is meant by the destruction/vanquishing/eradication/defeat of evil, one can only make the presentist solution work by adopting a number of additional assumptions that many will find unattractive.

How can we talk meaningfully about the past if it does not exist to be talked about? What gives time its direction? Is time travel possible? This defence of presentism - the view that only the present exists - makes an original contribution to a fast growing and exciting debate.

According to the presentist the present time is the only one that there is. Nevertheless, things persist. Most presentists think that things persist by enduring. Employing E. J. Lowe’s notion of identity-dependence, Jonathan Tallant argues that presentism is incompatible with any notion of persistence, even endurance. This consequence of Lowe’s ideas, if soundly drawn, is important. The presentist who chooses to deny persistence outright is a desperate figure. However, though Lowe’s notion is a legitimate and worthwhile one, this application (...) is faulty. The incompatibility of presentism and persistence is not part of Lowe’s heritage. A positive conclusion can be drawn. A form of persistence is compatible with presentism. It is one on which persistence is defined in tensed terms using an adverbial tense operator: x persists iff x exists and existed or will exist. Unsurprisingly, so understood persistence is endurance. The commonly held view is correct. (shrink)

I argue that, for all we know, there are perfectly ordinary actual entities that are temporal in the usual sense and yet never present, past, or future. This epistemic fact requires us to modify the theses of presentism and eternalism. More importantly, it generates three new and quite serious objections to presentism, which I formulate and partially evaluate in this paper.

Presentists, who believe that only present entities exist, face a problem of how to analyse tensed plural quantification. The idea, in broad outline, is that presentists can't employ the usual method for analysing tensed singular quantification, using primitive ‘slice’ tense operators, to analyse plurals. One option is to introduce a new theoretical primitive: a ‘span’‐operator. But there are reasons to worry about this option. For one, we might agree with Lewis that span‐operators are ill‐behaved or introduce unpalatable complexity. For another, (...) we might wish to avoid any additional theoretical primitives, regardless of whether spans can earn their keep alongside slices. In this paper, we offer a strategy for presentists to address the problem that requires only slice‐operators. Presentists who wish to avoid span‐operators, for whatever reason, should find our proposal attractive. (shrink)

Presentism and Eternalism are competing views about the ontological and temporal structure of the world, introduced and demarcated by their answers to questions about what exists and whether what exists changes. The goal of this chapter is to give the reader a clear understanding of Presentism and Eternalism, and a sense of some considerations used to critically assess the views by briefly rehearsing some of the main philosophical problems facing them.

There has been much recent debate about Presentism among those who believe the doctrine to be nontrivial and true, those who believe it to be nontrivial and false, and those who believe it to be trivial — either trivially true or trivially false. Formulating Presentism precisely is problematic, which accounts for some of the controversy.

In this paper, we show that presentism -- the view that the way things are is the way things presently are -- is not undermined by the objection from being-supervenience. This objection claims, roughly, that presentism has trouble accounting for the truth-value of past-tense claims. Our demonstration amounts to the articulation and defence of a novel version of presentism. This is brute past presentism, according to which the truth-value of past-tense claims is determined by the past (...) understood as a fundamental aspect of reality different from things and how things are. (shrink)

The presentist view of time is psychologically appealing. I argue that, ironically, contingent facts about the temporal properties of consciousness are very difficult to square with presentism unless some form of mind/body dualism is embraced.

Is reality three-dimensional and becoming real (Presentism), or is reality four-dimensional and becoming illusory (Eternalism)? Both options raise difficulties. I argue that we do not need to be trapped by this dilemma. There is a third possibility: reality has a more complex temporal structure than either of these two naive options. Fundamental becoming is real, but local and unoriented. A notion of present is well defined, but only locally and in the context of approximations.

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)

I argue that the most familiar forms of presentism can be seen, upon reflection, to involve two very different claims. Most arguments against such forms of presentism are directed against one of those claims, and I think that the arguments in question, properly formulated, are sound. In this paper, however, I want to set out an argument directed against the second claim, and to consider the prospects for that type of argument. My discussion is organized as follows. In (...) section 1, I describe four different forms that presentism can take, which I refer to as extreme presentism, austere, reductive presentism, tensed-facts presentism, and ersatzer presentism. Of these four forms of presentism, only the last two are popular today. In section 2, I briefly describe the more important types of objections that are standardly advanced against presentism. Then, in section 3, I argue that the dispute between presentists other than extreme presentists, on the one hand, and non-presentists, on the other, is very different from the dispute between, say, theists and atheists, and that this difference has important implications with regard to the types of objection that can be directed against presentism. Finally, in section 4, I set out the alternative line of argument against presentism that arises out of that difference. (shrink)

It is often claimed that the debate between presentism and eternalism is merely verbal, because when we use tensed, detensed or tenseless notions of existence, there is no difference in the accepted metaphysical statements between the adherents of both views. On the contrary, it is shown in this paper that when we express their positions making use, in accordance with intentions of the presentists and the eternalists, of the tensed notion of existence (in the case of the presentists) and (...) the detensed or tenseless notion (in the case of the eternalists), the controversy remains deep and very important for us, because both ontological claims express a different attitude to the existence of the flow of time. It is shown that not only does the proposed approach to presentism and eternalism exactly express the intentions of the adherents of both views but it also offers a better understanding of them joining together seemingly different theses maintained by the presentists and the eternalists, and explaining at the same time the dynamism of the presentists' ontology. The paper takes for granted that we should assess metaphysical theories in a similar way as we assess scientific theories, that is on the basis of their explanatory value. (shrink)

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.

After defining presentism, I consider four arguments that presentism and divine atemporality are incompatible. I identify an assumption common to the four, ask what reason there is to consider it true, and argue against it.

Presentism is the view, roughly speaking, that only presently existing things exist. Though presentism offers many attractive solutions to problems in metaphysics, philosophy of language, and philosophy of mind, it faces threats from two main sources: McTaggart and the special theory of relativity. This paper explores the prospects for fitting presentism together with the special theory. Two models are proposed, one which fits presentism into a relativistic setting (the cone model) and one which fits (...) the special theory into a presentistic setting (the surface model). It is concluded that there is no good reason arising from the special theory of relativity for rejecting presentism. Presentism is tenable here and preferable elsewhere. (shrink)

David Lewis [1986. On the Plurality of Worlds. Oxford: Basil Blackwell Publishers] famously declares that presentism is unable to allow for objects to persist and therefore should be rejected. The underlying idea is that presentism, in which only present entities exist, conflicts with persistence, which requires an object exist at multiple times. Both presentists and eternalists alike take this objection to be easily dismissed because the presentist can offer a tensed account of persistence in which an object persists (...) iff it exists and it will or did exist. Although it is the standard presentist response to Lewis, this strategy is inherently problematic. I show that if persistence is formulated in a tensed way, the presentist cannot distinguish a temporal series of unrelated instantaneous objects from a persisting object. Because there is no persistence in a temporal series of unrelated instantaneous objects, if the presentist cannot establish a difference between the two kinds of objects, the presentist’s account does not qualify as an adequate account of persistence. (shrink)

This paper is a partial defence of presentism against the argument from cross-time relations. It is argued, first, that the Aristotelian view of causation and persistence does not really depict these phenomena in terms of relations between entities existing at different times, and indeed excludes the possibility of such cross-time relations obtaining. Second, it is argued that to reject the existence of the past—and thereby be unable to ground the truth of claims about the past—does not lead to any (...) absurd consequences. (shrink)

In a recent publication in the European Journal for Philosophy of Science, Romero and Pérez claim to reveal new trouble for the already difficult life of presentism in relativistic spacetimes. Their argument purports to demonstrate the impossibility of postulating a viable present in the presence of black holes, in particular the Schwarzschild geometries. I argue that their argument is flawed, and that the Schwarzschild geometries they consider offer no novel threats to presentism. However, if we consider more (...) general black holes, different and more potent threats may be lurking in the dark. I discuss these threats and sketch how a presentist may respond, thus painting a more balanced picture of the way the existence of black holes might impact presentist metaphysics. At present there is no decisive verdict from black holes, but it turns out a close scrutiny of the developments in the relevant physics will be needed to see whether their import will remain so inconclusive. (shrink)

There is a philosophical tradition of arguing against presentism, the thesis that only presently existing things exist, on the basis of its incompatibility with fundamental physics. I grant that presentism is incompatible with special and general relativity, but argue that presentism is not incompatible with quantum gravity, because there are some theories of quantum gravity that utilize a fixed foliation of spacetime. I reply to various objections to this defense of presentism, and point out a flaw (...) in Gödel's modal argument for the ideality of time. This paper provides an interesting case study of the interplay between physics and philosophy. (shrink)

A recent account of presentist time travel involves a causal relation between events at two different and discontiguous times, and presentists cannot have such causal relations because presentism rules out the existence of at least one of the two relata in such a relation due to it being non-present. Additionally, presentists cannot have parodies of such causal relations for use in time travel stories because parodies are subject, at least, to the same limitations as the things being parodied. So, (...) the presentist has not successfully given an internally consistent account of presentist time travel. (shrink)

The most common form of endurantism takes enduring objects to be wholly located at every time they occupy. Such a view is believed to give rise to a problem concerning intrinsic change. My laptop may have been shut before, but it is currently open. Yet, if we understand endurantism as above, then my laptop is in possession of two contradictory properties: the shapes of being open and shut. This problem is known as the “problem of temporary intrinsics,” and, to avoid (...) it, two major kinds of moves have been made. The first is to meddle with the relationship between an enduring object and its properties by, for instance, claiming enduring objects bear their properties relationally to times rather than intrinsically. Many who have found this move unappealing have instead turned to presentism, claiming that endurantists should be presentists to avoid the problem. I take it that while both options can work, neither is optimal. Instead, I argue in favor of an alternative understanding of endurantism that allows endurantists to have it all: there is a version of endurantism that leaves the intrinsic properties of objects untouched, avoids the problem of temporary intrinsics, and does not require adopting presentism. (shrink)

In this paper I argue that presentism has a problem accounting forthe truth of statements whose truth conditions seem to require therebe relations that hold between present and non-present objects. Imotivate the problem and then examine several strategies for dealingwith the problem. I argue that no solution is forthcoming, and thispresents a prima facie problem for presentism.

Presentism—the thesis that only those things that are present exist—seems to face an insurmountable barrier in the Special Theory ofRelativity (STR). For the STR entails that simultaneity, and so the present, are relative to inertial frame. But if the present is the real and the present is relative, so too is in the real relative. But this cannot be. The real is absolute. But what is the Presentist to do? I suggest that she craft an alternative to the STR (...) that is empirically equivalent to it but makes rooms for a present, and a real, that are absolute. (shrink)
