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)

Eternalism is the view that all times are equally real. The relativity of simultaneity in special relativity backs this up. There is no cosmically extended, self-existing ‘now.’ This leads to a tricky problem. What makes statements about the present true? I shall approach the problem along the lines of perspectival realism and argue that the choice of the perspective does. To corroborate this point, the Lorentz transformations of special relativity are compared to the structurally similar equations of the Doppler (...) effect. The ‘now’ is perspectivally real in the same way as a particular electromagnetic spectrum frequency. I also argue that the ontology of time licensed by perspectival realism is more credible in this context than its current alternative, the fragmentalist interpretation of special relativity.

Eternalism is the view that the past, the present and the future exist simpliciter. A typical argument in favor of this view leans on the relativity of simultaneity. The ‘equally real with’ relation is assumed to be transitive between spacelike separated events connected by hyperplanes of simultaneity. This reasoning is in tension with the conventionality of simultaneity. Conventionality indicates that, even within a specific frame, simultaneity is based on the choice of the synchronization parameter. Hence the argument for (...) class='Hi'>eternalism is compromised. This paper lays out alternative eternalist strategies which do not hinge on hyperplanes. While we lack a rigorous proof for eternalism, there are still cogent reasons to prefer eternalism over presentism. (shrink)

The eternalist endurantist and perdurantist theories of persistence through time come in various versions, namely the two versions of perdurantism: the worm view and the stage view , and the two versions of endurantism: indexicalism and adverbialism . Using as a starting point the instructive case of what is depicted by photographs, I will examine these four views, and compare them, with some interesting results. Notably, we will see that two traditional enemies—the perdurantist worm view and the endurantist theories—are more (...) like allies : they are much less different than what is usually thought, and some alleged points of central disagreement fall prey to closer scrutiny. The aim of this paper is to examine carefully all those points, and to call attention to the places where the real differences between these views lie. I will then turn to the perdurantist stage view, and claim that with respect to some central issues it is the view that is the most different from the other three, but that in some places the reason why it different is also the reason why it is less satisfactory.

It is a widely held view in philosophy that propositions perform a plethora of different theoretical roles. Amongst other things, they are believed to be the semantic values of sentences in contexts, the objects of attitudes, the contents of illocutionary acts, and the referents of that-clauses. This assumption is often combined with the claim that propositions have their truth-values eternally. In this paper I aim to show that these two assumptions are incompatible: propositions cannot both fulfill the mentioned roles and (...) be eternally true or false. Following Kaplan and Lewis’s Operator Argument, I argue that compositional semantic values of sentences in contexts do not correspond to eternal propositions. Thus, either we regard the non-eternal entities that in fact realize the semantic role of propositions as also fulfilling the remaining propositional roles, or we abandon the assumption that there is a unique realizer of all the roles. The Operator Argument has recently come under attack, mainly for its tense-logical assumptions. However, rejecting these assumptions is not a sufficient defense of the compatibility of the two claims, since the extensional alternative to the tense-logical framework does not allow us to universally retain eternal propositions as compositional semantic values of sentences either.

In several recent papers, Daniel Deasy has argued that the presentism–eternalism debate is unclear and should be abandoned. According to Deasy, there is no way of spelling out the predicate ‘is present’ that leads to a satisfactory definition of presentism: on some interpretations, presentism turns out to be compatible with eternalism, on others, it is clearly false or unacceptable for other reasons. The aim of this paper is to show that this line of argument should be resisted: if (...) the predicate ‘is present’ is spelled out in terms of where things are located, the result is a definition of presentism that is neither compatible with eternalism nor clearly false. There is thus no need to abandon the debate between presentists and eternalists. (shrink)

The main claim that I want to defend in this paper is that the there are logical equivalences between eternalism and perdurantism on the one hand and presentism and endurantism on the other. By “logical equivalence” I mean that one position is entailed and entails the other. As a consequence of this equivalence, it becomes important to inquire into the question whether the dispute between endurantists and perdurantists is authentic, given that Savitt (2006) Dolev (2006) and Dorato (2006) have (...) cast doubts on the fact that the debate between presentism and eternalism is about “what there is”. In this respect, I will conclude that also the debate about persistence in time has no ontological consequences, in the sense that there is no real ontological disagreement between the two allegedly opposite positions: as in the case of the presentism/eternalism debate, one can be both a perdurantist and an endurantist, depending on which linguistic framework is preferred.

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)

Anselm holds that God is timeless, time is tenseless, and humans have libertarian freedom. This combination of commitments is largely undefended incontemporary philosophy of religion. Here I explain Anselmian eternalism with its entailment of tenseless time, offer reasons for accepting it, and defend it against criticisms from William Hasker and other Open Theists. I argue that the tenseless view is coherent, that God’s eternal omniscience is consistent with libertarian freedom, that being eternal greatly enhances divine sovereignty, and that the (...) Anselmian view supports the contention that the Bible is relevant today far better than does Open Theism. (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.

In her Transient Truths, Berit Brogaard defends temporalism about proposition content from the more traditional eternalist views. I argue that both temporalism and eternalism are equally capable of accommodating all the data, and thus suggest that we should adopt a neutralism that holds there is no serious or resolvable dispute. Contra Brogaard, I argue that neither disagreement patterns nor belief dynamics favor temporalism over eternalism. I also suggest that Brogaard's defense of operator over quantificational semantics for tense is (...) unnecessary, because quantificational tense semantics can be given a temporalist reading, and operator tense semantics can be given an eternalist reading.

Eternalist tensism is the thesis that tense is an objective feature of reality as it is in itself and that all times, whether past, present, or future, are equally real. I develop an argument from qualitative change in favor of tensism and defend eternalism from an argument from fatalism.

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.

It is often assumed that an eternalist and a presentist will have the same emotional response to life's events because, regardless of one's metaphysical beliefs, we all have the same phenomenological experience of time passing and it is this experience that is relevant to emotional response. I question the assumption that beliefs about the metaphysics of time can have little impact on one's emotional responses and establish the position that scientific and metaphysical beliefs can offer succour.

In his 2004 paper ‘Tensed Quantifiers’, David Lewis presented an apparently powerful case for eternalism by arguing that we cannot account for the truth-conditions of sentences like ‘There have been forty-four presidents of the United States’ and ‘There will be five more presidents of the United states’ and maintain a non-revisionary attitude towards their truth-values, without committing to the existence of ‘past’ and ‘future’ things. Related arguments can be found in works by Ted Sider, and by Zoltan Gendler Szabó. (...) We can call the fully developed form of this argument the Argument from Semantics. In this paper, I counter the AfS by showing that these truth-conditions can be captured without commitment to the existence of things—such as Socrates and Abraham Lincoln—which we take to have existed but not to exist, or things—like the par..

Normally, when we notice a change taking place, our conscious experience has a corresponding quality of phenomenal change. Here it is argued that one's experience can have this quality at or during a time when there is no change in which phenomenal properties one instantiates. This undermines a number of otherwise forceful arguments against leading metaphysical theories of change, but also requires these theories to construe change as a secondary quality, akin to color.

I present a discussion of some issues in the ontology of spacetime. After a characterisation of the controversies among relationists, substantivalists, eternalists, and presentists, I offer a new argument for rejecting presentism, the doctrine that only present objects exist. Then, I outline and defend a form of spacetime realism that I call event substantivalism. I propose an ontological theory for the emergence of spacetime from more basic entities. Finally, I argue that a relational theory of pre-geometric entities can give rise (...) to substantival spacetime in such a way that relationism and substantivalism are not necessarily opposed positions, but rather complementary. In an appendix I give axiomatic formulations of my ontological views. (shrink)

This chapter discusses the metaphysical view referred to by Harry Silverstein as “four-dimensionalism,” but referred to in this chapter as “eternalism.” In contrast to presentism, eternalism posits that purely past and purely future objects and events exist. If a person goes out of existence at the moment of death, the problem arises as to how death is bad for its victim. According to Silverstein, this problem arises from the truth of the “Values Connect with Feelings” thesis, according to (...) which it must be possible for someone to have feelings about a thing in order for that thing to be bad for that person. The badness of death may entail eternalism, but it is for an entirely different reason. Eternalism must be true in order for there to be a time at which death is bad for its victim. These two conflicting views are discussed in this chapter. (shrink)

This thesis considers the relationship between the ontology of time and the passage of time, and concludes that the best way to understand this relationship is found in the combination of eternalism with the view that the passage of time is an objective, irreducible fact about the spatio-temporal world. The steps I take to reach this conclusion are as follows: first, I propose that eternalism is the best ontological basis from which to consider temporal passage; second, I argue (...) that the moving spotlight theory, which attempts to reconcile eternalism with temporal passage, is an inadequate representation of the relationship between eternalism and temporal passage; third, I suggest that temporal passage is best understood as a mind-independent phenomenon. I argue that eternalism is preferable to presentism insofar as presentism suffers from inconsistencies that eternalism both avoids and easily solves. I then defend the rejection of the moving spotlight theory by an appeal to the incoherency of the moving now. Finally, I dismiss mind-dependent temporal passage in favour of mind-independent temporal passage based on the irreducibility of temporal passage in and of itself. (shrink)

In this paper, I develop an argument against eternalism, which is similar to the widely discussed grounding problem for presentism. It has recently been argued by many that presentism should be rejected on grounds that its sparse ontology is not suited to underwrite the healthy dose of realism we all share about the past. My aim basically is to add a new twist to the debate, by showing that actually eternalists are no better off than their rivals. In particular, (...) I argue that the eternalist’s ontology does not have the appropriate shape to ground true propositions about the past. (shrink)

Suppose that at the moment of death, a person goes out of existence.1 This has been thought to pose a problem for the idea that death is bad for its victim. But what exactly is the problem? Harry Silverstein says the problem stems from the truth of the “Values Connect with Feelings” thesis (VCF), according to which it must be possible for someone to have feelings about a thing in order for that thing to be bad for that person (2000, (...) 122). But in order for a person to have feelings about a thing, the person and the thing must coexist in some way. Thus Silverstein feels compelled to endorse a metaphysical view he calls “four-dimensionalism,” but which I prefer to call “eternalism”: the view that purely past and purely future objects and events exist.2 I agree with Silverstein that the badness of death entails eternalism. But the reason is different. Eternalism must be true in order for there to be a time at which death is bad for its victim. Death is bad for its victim at all those times when the victim is worse off for having died: namely, the times when he would have been living a good life had that death not occurred.3 Silverstein rejects this view; he thinks there is something wrong with the very question of when death is bad for its victim. In what follows I argue that Silverstein has not shown the relevance of eternalism to VCF or the badness of death, and I defend my view about the time of death’s badness against Silverstein’s arguments.

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.

How is the debate between presentism and eternalism to be characterized? It is usual to suggest that this debate about time is analogous to the debate between the actualist and the possibilist about modality. I think that this suggestion is right. In what follows I pursue the analogy more strictly than is usual and offer a characterization of what is at the core of the dispute between presentists and eternalists that may be immune to worries often raised about the (...) substantiality of the debate. I suggest that the debate be characterized in Lewisean terms and define positions I call *Lewisean* eternalism and anti-*Lewisean*' presentism (analogous to Lewisean possibilism and anti-Lewisean actualism). I explain some advantages of the proposal and discuss some objections. I conclude that pursuing the analogy strictly offers the prospect of giving clear sense to a controversy which otherwise seems to many deeply obscure. (shrink)

My students sometimes worry that if eternalism is true then they can’t have libertarian freedom. They aren’t alone, as this sentiment is also expressed, albeit typically briefly, by various philosophers. However, somewhat surprisingly, those working within the free will literature have largely had nothing to say about libertarianism’s relationship to time, with this also being similar in the case of those working in the philosophy of time, apart from some work which has mainly focused on nonlibertarian views of freedom. (...) In this short paper I note why I’m currently unconvinced that there’s an incompatibility between eternalism and libertarianism, and in doing so one will see why I think they are compatible.

Eternalism, the view that what we regard locally as being located in the past, the present and the future equally exists, is the best ontological account of temporal existence in line with special and general relativity. However, special and general relativity are not fundamental theories and several research programs aim at finding a more fundamental theory of quantum gravity weaving together all we know from relativistic physics and quantum physics. Interestingly, some of these approaches assert that time is not (...) fundamental. If time is not fundamental, what does it entail for eternalism and the standard debate over existence in time? First, I will argue that the non-fundamentality of time to be found in string theory entails standard eternalism. Second, I will argue that the non-fundamentality of time to be found in loop quantum gravity entails atemporal eternalism, namely a novel position in the spirit of standard eternalism. (shrink)

We distinguish three debates within current analytic philosophy of time: a first one regarding the passage of time, where static and dynamic views oppose each other; a second one concerning the existence or non-existence of temporal entities, where presentism and eternalism are main contenders; a third one about permanence, where the conflict is between permanentism and temporarism. We then consider how Severino's Parmenidean view may be related to such debates and argue that it is best viewed as a kind (...) of temporarist static eternalism. (shrink)

Ever since the now infamous comments made by Hermann Minkowski in 1908 concerning the proper way to view space-time, the debate has raged as to whether or not the universe should be viewed as a four-dimensional, unified whole wherein the past, present, and future are equally real or whether the views espoused by the possibilists, historicists, and presentists regarding the unreality of the future (and, for presentists, the past) are best. Now, a century after Minkowski’s proposed blockworld first sparked debate, (...) we seek a more conclusive argument in favor of the eternalist picture of space-time. Utilizing an argument based on the relativity of simultaneity in the tradition of Putnam and Rietdijk and novel but reasonable assumptions as to the nature of “reality”, we will show that the past, present, and future are equally real, thus ruling out presentism and other theories of time that bestow special ontological status to the past, present, or future as untenable. Finally, we will respond to our critics who would suggest that: 1) there is no metaphysical difference between the positions of eternalism and presentism, 2) the present must be defined as the “here” as well as the “now”, or 3) presentism is correct and our understanding of relativity is incomplete because it does not incorporate a preferred frame. We call eternalist response 1 deflationary since it purports to dissolve or deconstruct the age-old debate between the two views and response 2 compatibilist because it does nothing to alter special relativity (SR) arguing instead that SR unadorned has the resources to save presentism. Response 3 we will call incompatibilism because it adorns SR in some way in order to save presentism a la some sort of preferred frame. We will show that neither move 1 nor 2 can save presentism and move 3 is not well motivated at this juncture except as an ad hoc device to refute eternalism. (shrink)

Four-dimensionalists think that we persist over time by having different temporal parts at each of the times at which we exist. Eternalists think that all times are equally real. Deprivationists think that death is an evil for the one who dies because it deprives them of something. I argue that four-dimensionalist eternalism, conjoined with a standard deprivationist account of the evil of death, has surprising implications for what we should think about the evil of death. In particular, given these (...) assumptions, we will lack any grounds for thinking that death is an evil for some individuals for whom we would antecedently expect it to be an evil, namely those individuals who cease to exist at death. Alternatively, we will only have some grounds for thinking that death is an evil for certain individuals for whom we might antecedently be more inclined to think death is not an evil, namely those individuals who survive death, in the sense that they continue to exist after death.

In the early twentieth century, many philosophers in America thought that time should be taken seriously in one way or another. George P. Adams (1882-1961) argued that the past, present and future are all real but only the present is actual. I call this theory ‘actualist eternalism’. In this paper, I articulate his novel brand of eternalism as one piece of his metaphysical system and I explain how he argued for the view in light of the best explanations (...) of temporal experience and the present. I argue that his exploitation of analogies between time and modality offer some lessons for current debates about time such as the importance of providing a temporal epistemology. I also extract what I call the temporal boundary problem and argue that it gives rise to an unaddressed challenge for presentists and growing block theorists. (shrink)

Patrick Toner has argued that eternalism, the doctrine that all times are ontologically on par, conflicts with the Catholic view of judgment as based on the state of the soul at death. For, he holds, it is arbitrary that judgment should be based on what happened at some particular time, unless, as presentism holds, that time is the only that really exists. I shall argue that his argument fails because the eternalist can say that judgment is simultaneous with the (...) state of soul that is being judged, and there is nothing arbitrary about judging something at t on the basis of its state at the same time t.

In this paper I argue that the debate between the so-called “presentists” – according to whom only the present is real – and the “eternalists”, according to whom past present and future are equally real, has no ontological significance. In particular, once we carefully distinguish between a tensed and a tenseless sense of existence, it is difficult to find a single ontological claim on which the two parties could disagree. Since the choice of using a tense or a tenseless language (...) is dictated by purely pragmatic reasons, we should abstain from bringing to bear pseudo-debates generated by the “tensed” or the “tenseless theories” of time on the question of understanding the philosophical implications of contemporary spacetime theories, or notions like becoming, change and persistence in time.

In contemporary Western culture, death has been widely censured because of its conceptual implications; it lies at the boundaries between reductionism and metaphysics. There is not yet an efficacious epistemology able to solve this contraposition and its consequent collision with science and tradition. This article analyzes Near Death Experiences as a prototypical argument in which the two perspectives conflict. Specifically, it analyzes the epistemological antinomies of the ontological representations of death, inhering in passage versus absolute annihilation. Indeed, the NDEs theme (...) permits the examination of the logical contradiction between monistic reductionism and its ontological counterpart to improve the discovery of a new paradigm that integrates the ecological with eternalist views.

There are many questions we can ask about time, but perhaps the most fundamental is whether there are metaphysically interesting differences between past, present and future events. An eternalist believes in a block universe: past, present and future events are all on an equal footing. A gradualist believes in a growing block: he agress with the eternalist about the past and the present but not about the future. A presentist believes that what is present has a special status. My first (...) claim is that the familiar ways of articulating these views result in there being no substantive disagreement at all between the three parties. I then show that if we accept the controversial truthmaking principle, we can articulate a substantive disagreenment. Finally, I apply this way of formulating the debate to related questions such as the open future and determinism, showing that these do not always line up in quite the way one would expect. (shrink)

The doctrine is unquestionably Nietzsche’s most puzzling, and it has been interpreted in two distinguishable ways: as a cosmology or an ethical imperative. The cosmological basis of the doctrine can be found only in Nietzsche’s literary estate, the Nachlass, in notes not designated for publication. The normative import of the doctrine of eternal recurrence, on the other hand, finds articulation in virtually every work written by Nietzsche after 1881. It is of some importance to note in this connection that all (...) Nietzsche scholars have taken the cosmological formulation to be the clear one, mistakenly I believe, and have ignored the fact that Nietzsche himself suppressed it. (shrink)

In this discussion I argue that, given the possibility of travel to the past, eternalists face a dilemma. They must choose between fatalism and the denial of an intuitive claim about what a traveller to the past cannot do. The eternalist should deny this seemingly intuitive claim which is in fact a version of fatalism about the past.

Against my interpretation, Brian Leftow argues that Anselm of Canterbury held a presentist theory of time, and that presentism can be reconciled with Anselm’s commitments concerning divine omnipotence and omniscience.

I articulate my puzzlement in a way that I hope moves the discussion forward. Second, Leftow’s examples to demonstrate that presentism can be reconciled with Anselm’s understanding of the divine (...) nature assume a mode of divine knowing which is different from what Anselm proposes.

Humean compatibilism combines a Humean conception of laws of nature with a strong dual-ability condition for free will that requires that agents possess the ability to decide differently when they make a free decision. On the Humean view of laws of nature, laws of nature are taken to be contingent non-governing descriptions of significant regularities that obtain in the entire history of the universe. On Humean compatibilism, agents are taken to possess dual ability when making free decisions because what the (...) laws of nature will finally be is (at least partially) dependent upon how an agent decides. In this paper, I argue that the tenability of Humean compatibilism depends in part upon what theory of time is correct. More specifically, I argue that Humean compatibilism is untenable in a deterministic universe if eternalism is true. (shrink)

In this paper, we argue against eternalism on the basis of certain phenomenological considerations regarding our experiential life in a relatively novel way. Contrary to well-known phenomenological arguments that attempt to refute tenseless theories of time, our argument that we call the Transcendental Phenomenological Argument against Eternalism is against both tenseless and tensed versions of eternalism. The argument is based on the fact that one experiences a phenomenologicalsuccessionof experiences, and it shows that perdurantist forms of eternalism (...) have to either deny this fact or should embracead hocand metaphysically implausible assumptions about the nature of the mind. As we argue, neither of these options seems to be too promising. (shrink)

In the current paper, I enter into debate with Marcin Tkaczyk and the chosen Anglo-Saxon analytic philosophers of religion to discuss the theological version of the problem of future contingents. I take into consideration some varieties of Ockhamism (retroactivism)—the position denying the temporal necessity (non-determination) of all past events and allowing some form of retroactivity. Strong Ockhamism postulates real retroactive causation, moderate Ockhamism limits it to the meanings of physical and psychical events, and weak Ockhamism replaces the notion of retroactive (...) causation with that of retroactive dependence. I compare different forms of retroactivism with eternalism (of Boethius, St. Anselm of Canterbury, and St. Thomas Aquinas) to show that the latter has significant advantage. At the same time, I point out that eternalism in its presentist and relativist version (proposed by Brian Leftow) avoids the objections put forward against it, and that, within such eternalism, the problem of future contingents does not arise.
