Empirical work has lately confirmed what many philosophers have taken to be true: people are ‘biased toward the future’. All else being equal, we usually prefer to have positive experiences in the future, and negative experiences in the past. According to one hypothesis, the temporal metaphysics hypothesis, future-bias is explained either by our beliefs about temporal metaphysics—the temporal belief hypothesis—or alternatively by our temporal phenomenology—the temporal phenomenology hypothesis. We empirically investigate a particular version of the temporal belief hypothesis according to (...) which future-bias is explained by the belief that time robustly passes. Our results do not match the apparent predictions of this hypothesis, and so provide evidence against it. But we also find that people give more future-biased responses when asked to simulate a belief in robust passage. We take this to suggest that the phenomenology that attends simulation of that belief may be partially responsible for future-bias, and we examine the implications of these results for debates about the rationality of future-bias.

This chapter argues for a notion of time that allows time travel. In order to time traveling to happen, in contrast to Presentism, the chapter demonstrates that we can change the past and we have some place where to travel. It shows the advantages of a non-presentist ontology that advocates for indeterminacy of future facts based not on its absence of truth-value, but on the overdetermination of future facts. The conclusion is that to break the causal chain is impossible in (...) we are placed in the same causal line. But if we rethink the time traveling as a trans-world traveling, it is possible to open a new causal line anytime that someone travel in time, to the past as well as to the future. (shrink)

The paper will explore a key tension between eternity and temporality that comes to the fore in the seeming contradiction between freedom of the human will and divine foreknowledge of future contingents. It will be claimed that Duns Scotus’s adaptation of Thomas Aquinas’s view reduces the tension between a human being’s freedom and divine foreknowledge of future contingents to the question of how to conflate the now of eternity and our experience of the instantaneous now. Scotus’s account of the matter (...) is unfortunately not satisfying and it is the purpose of this paper to develop this insight further in a speculative manner. In order to make such co-nowness possible, it will be asked how the eternal and the temporal can co-cause together. This problem will be tackled through a development of Scotus’s doctrine of the will taken elsewhere, in order to examine how the divine and the human wills can occur together. It will be claimed that such co-willing produces a co-nowness of the eternal and the instantaneous ‘nows’ which generates a logical temporal movement. (shrink)

Tenseless theorists assert that the relational structure of earlier/later is the essential structure of time. Using B-notions, so they think, we speak about time ‘as it is’ in a metaphysical sense and hence from the outside of our subjective perspective on it. I suggest on the contrary that the relational structure of earlier/later is part of our own intellectual structuring within the access to temporal phenomena. Furthermore it is essentially characterized by the structure of juxtaposition which originates in spatial experience (...) rather than in temporal. In order to show this I consult Henri Bergson’s analysis of our temporal experience on the one hand and of our intellectual practice on the other hand. I will conclude that it is not unplausible to take the relational account of time to be more closely connected to the nature of our intellect than to the nature of time itself. (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.

Different versions of the A-theory of time are traditionally defined in terms of whether everything is present, or whether there are also past and future things. In this paper I argue that the traditional way of defining A-theories should be abandoned. I focus on the traditional definition of presentism, according to which always, everything is present. First, I argue that there are good reasons to reject all the most plausible interpretations of the predicate ‘is present’ as it appears in the (...) traditional definition of presentism. It follows that there are also good reasons to reject the most plausible interpretations of the traditional definitions of the other A-theories. I then argue that there is a better way of defining the A-theories, in terms of the question of whether existence has a beginning and an end. Finally, I argue that what goes for the traditional definition of presentism goes for the traditional definition of its modal analogue actualism, according to which necessarily, everything is actual : there are good reasons to reject the traditional definition of actualism in favour of a definition in terms of contingent existence.

Presentism is typically characterised as the thesis that everything is present, and therefore there are no dinosaurs or Martian presidential inaugurations. Putting aside the vexed question of exactly what it is to be present in this context, this thesis seems quite straightforward. However, a number of authors—such as Merricks, Lombard, Meyer, Tallant and Sakon —have argued that Presentism so characterised is either trivially true or false even by Presentist lights. This is the so-called Triviality Argument against Presentism. In this paper (...) I show that three of the four premises of the Triviality Argument are plausibly false. I conclude that Presentists have nothing to fear from the Triviality Argument. (shrink)

The aim of this paper is to describe and defend the moving spotlight theory of time. I characterise the moving spotlight theory as the conjunction of two theses: permanentism, the thesis that everything exists forever, and the A-theory, the thesis that there is an absolute, objective present time. I begin in Sect. 2 by clearing up some common misconceptions about the moving spotlight theory, focusing on the discussion of the theory in Sider. In doing so, I also fill-out the barebones (...) picture of the moving spotlight theory as the conjunction of permanentism and the A-theory. In Sect. 3 I show how moving spotlighters can avoid the two common objections to their view, the McTaggartian argument that the view is contradictory, and the epistemic argument that the view implies that we should believe we are not located at the present moment. I conclude that the moving spotlight theory does not deserve its current relative unpopularity. (shrink)

According to the A-theory of time some instant of time is absolutely present. Many reject the A-theory on the grounds that it is inconsistent with current spacetime physics, which appears to leave no room for absolute presentness. However, some reject the A-theory on purely philosophical grounds. In this article I describe three purely philosophical arguments against the A-theory and show that there are plausible A-theoretic responses to each of them. I conclude that, whatever else is wrong with the A-theory, it (...) is not obviously a philosophically suspect theory. (shrink)

The age old conflict between logical analysis and phenomenological study revealed by different philosophical treatments of our experience of temporal passage are discussed in the present paper. Temporal passage is found to be problematic because philosophers entertain conflicting views regarding the status of the passage of time. As logical analyses prove temporal passage as unreal or illusory and phenomenological study of our experience of temporal passage considers it to be a fundamental structure of our life, the conflict regarding the status (...) of the passage of time emerges. In this paper our aim will be to explore gradually different logical analyses of our experience of temporal passage provided by philosophers of both classical India and the West on the one hand and also to discuss some of the phenomenological treatments of our experience of temporal passage provided by some continental philosophers to show the conflict between the results of these two philosophical treatments. Finally, we would like to state that since this conflict culminates into the conflict between reason and experience, it is not possible to resolve the conflict in the present life form in which both these categories have their distinctive roles to play.

The A-theory and the B-theory advance competing claims about how time is grounded. The A-theory says that A-facts are more fundamental in grounding time than are B-facts, and the B-theory says the reverse. We argue that whichever theory is true of the actual world is also true of all possible worlds containing time. We do this by arguing that time is uniquely groundable: however time is actually grounded, it is necessarily grounded in that way. It follows that if either the (...)

A-theorists and B-theorists debate whether the "Now" is metaphysically distinguished from other time slices. Analogously, one may ask whether the "I" is metaphysically distinguished from other perspectives. Few philosophers would answer the second question in the affirmative. An exception is Caspar Hare, who has devoted two papers and a book to arguing for such a positive answer. In this paper, I argue that those who answer the first question in the affirmative---A-theorists---should also answer the second question in the affirmative. This (...) is because key arguments in favor of the A-theory are more effective asarguments in favor of the resulting combined position, and key arguments against the A-theory are ineffective against the combined position.

The purpose of this paper is to present a philosophical worldview, specifically metaphysical. This is important precisely to obtain a generalist view of reality, at a time when philosophical discussions are becoming increasingly specialized. The metaphysical worldview presented here is a general perspective on time, space, matter, laws of nature, the mind and the normativity. In order to achieve such goal, (1) we will talk about the nature of philosophy and its relation to the construction of a worldview, (2) we (...) will discuss some arguments to talk about the nature of the aforementioned entities, and (3) we will conclude by presenting a unified metaphysical worldview that takes these arguments into account.

Perceptual experience is present-directed in the sense that what we perceptually experience seems to be temporally present, while what we remember or imagine does not. One way of explaining this contrast is to claim that perceptual experience uniquely involves awareness of the property of presence (either conceived as an observer-independent property of the present time or as a relation of simultaneity between an event and one’s experience of it). I argue against this explanation and in favour of one on which (...) perception’s feeling of present-orientation is explained in terms of the feeling of aptness for action guidance that characterizes perceptual experience. I argue that an advantage of this view is that, unlike its rivals, it can make perception’s present-directedness straightforwardly compatible with the specious present theory as an account of experiences of motion and change.

This book brings together papers from a conference that took place in the city of L'Aquila, 4–6 April 2019, to commemorate the 10th anniversary of the earthquake that struck on 6 April 2009. Philosophers and scientists from diverse fields of research debated the problem that, on 6 April 1922, divided Einstein and Bergson: the nature of time. For Einstein, scientific time is the only time that matters and the only time we can rely on. Bergson, however, believes that scientific time (...) is derived by abstraction, even in the sense of extraction, from a more fundamental time. The plurality of times envisaged by the theory of Relativity does not, for him, contradict the philosophical intuition of the existence of a single time. But how do things stand today? What can we say about the relationship between the quantitative and qualitative dimensions of time in the light of contemporary science? What do quantum mechanics, biology and neuroscience teach us about the nature of time? The essays collected here take up the question that pitted Einstein against Bergson, science against philosophy, in an attempt to reverse the outcome of their monologue in two voices, with a multilogue in several voices.

Does it make sense to think of eternal life not as an unending continuation of life subsequent to death but as fully actualized in one’s present mortal and finite life? After outlining conceptual and moral reasons for being troubled by the notion of an endless life, this article draws upon the thought of major Christian theologians and philosophers of religion to expound the idea of eternal life as a possession exclusively of the life one is presently living. Supplementing the claims (...) of religious thinkers with notions of four-dimensionalism and eternalism from theoretical physics and the philosophy of time, and considering important objections to the conception of eternal life in question, I argue for both the conception’s intelligibility and its ethical and spiritual profundity.

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)

An explanatorily powerful approach to the modal dimension of knowledge is Robert Nozick’s idea that knowledge stands in a tracking relation to the world. However, pinning down a specific modal condition has proved elusive. In this paper, I offer a diagnosis and a positive proposal. The root of the problem, I argue, is the unquestioned assumption that tracking is a matter of directly preserving conformity between what is believed and what is the case in certain possible worlds. My proposal is (...) that what we track is whether the conditions for belief formation are appropriate in such worlds. Accordingly, we indirectly track the truth by ensuring that we only use our methods of belief formation in conditions that make it likely that conformity is preserved between what is believed and what is the case.

Tensism holds that the present moment has a special status that sets it apart from the past and the future, independently of perceivers. One of the main objections to this view has been Einstein’s argument from special relativity, which aims at showing that absolute simultaneity is a myth. We argue that the moving observer in a causal variant of Einstein’s original thought experiment is subject to a temporal illusion. Owing to the analogy of the cases, this casts doubt on the (...) conjectures that there is no privileged frame of reference and that special relativity poses a problem for tensism. (shrink)

A book review of R. Paul Thompson's "A Remarkable Journey: The Story of Evolution.

ABSTRACT This essay is a critical introduction to the second part of the special issue Time and Reality. The volume contains responses to papers appeared in the first part, as well as many original articles. The aim of this introduction is to frame these works within the general arena of the philosophy of time, highlighting a number of recurrent themes. A central theme that emerges is a difficulty in pinning down the ontological structure underlying dynamicity and passage without postulating a (...) primitive notion of transiency that is conceptually independent from the instantiation of tense properties. I argue that this has far reaching implications. (shrink)

We argue that the view that we misperceive time as passing is self-undermining.

ABSTRACT This essay is an introduction to Time and Reality I, the first part of a special issue dedicated to the philosophy of time. Here I outline a number of new trends in philosophical theorizing about time, detailing how the various contributions fit into the picture. I argue that there has been a potentially misleading tendency to separate the debate over the passage of time from the debate over the reality of tense. This has obscured a number of interesting philosophical (...) questions. One of the aims of this volume is to bring these two issues together, where they belong. I argue that many contributions to it go in the right direction. The contributions to this volume also establish uncharted philosophical junctures between Metaphysics, Aesthetics, Morality, and the Philosophy of Mind. (shrink)

There are two no-change objections that can be raised against the B-theory of time. One stems from the observation that in a B-theoretic scenario changes of determinations can only be represented by propositions which have eternal truth values. The other derives from the principle that nothing can vary over a period of time if it doesn’t instantiate a state of change at all the instants of time which compose it. Here I argue that both objections apply to all comparative conceptions (...) of change, regardless of whether they take tense seriously or not. It follows that, contrary to what is widely believed, A-theoretic accounts of time are not immune to no-change objections, just in virtue of being realist about tense. A-theorists must either accept the conclusion that time, according to their account, does not flow, or put forward an account of flow that is not comparative. A number of difficulties with both of these options are discussed. (shrink)

İslam felsefesinin tartışmasız en önemli filozoflarından biri olan İbn Sina, dönemindeki yoğun Aristoteles etkisine karşılık, Aristoteles’in sisteminden bağımsız yeni bir zaman sistemi kurmuştur. Şifa isimli kitabında bu sistemi sunan İbn Sina, aynı zamanda hareket, hız, mekansal büyüklük gibi belli kavramların yanında bölünebilir bir büyüklük olan ve zorunlu bir şekilde öncelik ve sonralığa sahip olan bir kapasite olarak tanımladığı imkana dayalı bir zamanın gerçekliği savunusu yapmakla birlikte bu kavramların anlam kazanabilmesi için zaman kavramına ihtiyacımız olduğunu göstermiştir.Zamanın gerçekliği sorusu, güncel felsefenin aktörlerinden (...) de büyük dikkat çekmiştir. Bu isimlerden biri olan J. Ellis McTaggart, hayli tartışmalı olmasının yanısıra etkili de olan “Zamanın Gerçekdışılığı” başlıklı makalesinde zamanın bir illüzyondan ibaret olduğunu tartışmıştır. McTaggart, gerek bu makalede gerekse Varoluşun Doğası isimli kitabında zamanın gerçek olmadığını ve zamana dair verdiğimiz her tanımın döngüsel, çelişkili veya yetersiz olduğunu savunmuştur. McTaggart, bu ispatını zamandaki anların birbirine nispetle iki farklı şekilde sınıflandırılabileceği varsayımı üzerine kurgulamıştır. Buna göre A serisi, zamandaki anları geçmiş, şu an ve gelecek şeklinde konumlandırırken B serisi, öncelik ve sonralık ilişkisi ile konumlandırmaktadır. Bu çalışma, İbn Sina’nın sunduğu zaman sisteminin McTaggart’ın B serisi ile uyumlu olup olmadığı sorusunu cevaplamayı amaçlamaktadır.Anahtar kelimeler: İbn Sina, Zaman, Mekansal Büyüklük, İmkan, Hareket, McTaggart, B serisi.

A certain mythology has been perpetuated in discussions of philosophy of time. It has been contended that the adoption of a particular theory of time, what I will call the “Non-dynamic Theory of Time” results in a commitment to Fatalism. This unwanted, if not intolerable baggage, is said to be avoided only by jettisoning NDTT and espousing what I will call the “Dynamic Theory of Time”. What I hope to show is that the truth of the matter is almost completely (...) the reverse; while NDTT has absolutely no Fatalistic ramifications, DTT, when it is conjoined with a most plausible supposition, does.

Does mere passage of time have causal powers ? Are properties like "being n days past" causally efficient ? A pervasive intuition among metaphysicians seems to be that they don't. Events and/or objects change, and they cause or are caused by other events and/or objects; but one does not see how just the mere passage of time could cause any difference in the world. In this paper, I shall discuss a case where it seems that mere passage of time does (...) have causal powers : Sydney Shoemaker's (1969) possible world where temporal vacua (allegedly) take place. I shall argue that Shoemaker's thought-experiment doesn't really aim at teaching us that there can be time without change, but rather that if such a scenario is plausible at all (as I think it is) it provides us with good reasons to think that mere passage of time can be directly causally efficient.

This paper sketches a metaphysical view according to which the furniture of the universe is made of indexicals. The view draws from work in the philosophy of language and thought concerning demonstratives, proper names and other deictic operations. It also draws on Levinas‘ conception of the Other as beyond any substantive description. Indexicalism, as I call it, is compared with object-oriented views such as Harman‘s and Garcia‘s. Indexicalism lapses into paradox concerning totality and proves to be self-destructive. It is defended, (...) however, as a paradoxico-metaphysics. (shrink)

The last thirty years have brought about a fundamental revision of historical epistemology. So intense a concentration on the nature of history as a form of inquiry has diminished attention given to the thing that history inquires into: the nature of the past itself. Too readily, that entire domain has turned into a place for dreams, as Hayden White put it: a lost world only available now through the imagination of the author and subject to aesthetic whim. The next thirty (...) years will, I propose, be the period in which ontology returns to the center of historical theory. And nothing short of the reconceptualization of the past—indeed of time itself—must be its objective. It must achieve that objective, moreover, in establishing arguments that are congruent with what revisions of epistemology have taught us about the limits of historical knowledge and the inevitability of textual representation. This paper enters this field by discussing some of the issues involved in rethinking the place of time in historical constructions since Bergson. It demonstrates the confusions inherent in spatial reductions of temporality, which historians have done so much to entrench rather than eradicate, and argues that historians have yet to accommodate the fundamental conceptual shifts inaugurated by Heidegger. It then moves to propose a methodological doctrine to which I have given the name "chronism" and seeks to sketch the utility of such a doctrine for bringing one form of presence—that of authenticity—back into the domain of historical study. Doing so invites a number of conceptual and practical difficulties that the paper will address in its conclusions; these may disturb those who have closed their minds to anything beyond the present. Taking ontology seriously interferes both with structuralist assumptions about the nothingness of time and with some of the styles of historical representation that have become fashionable in the postmodern climate. There may be painful lessons to be learned if we are to rescue the past from its current status as a nonentity. (shrink)

The B-theory of time holds that McTaggart’s A-series of past, present, and future is reducible to the B-series of events running from earlier to later. According to the date-theory—originally put forth by J.J.C. Smart and later endorsed by by D.H. Mellor—the truth conditions of tensed or Asentence-tokens can be given in terms of tenseless or B-sentences and, therefore, A-sentence-tokens do not ascribe any A-determinations of pastness, presentness, or futurity. However, as Nathan Oaklander has argued, the date-theory does not provide an (...) adequate analysis of the ontological truth conditions of irreducible A-propositions. I show that the co-reporting theory—which holds that for every A-sentence-token there is a B-sentence that differs in sense but reports the same event or state of affairs—escapes the objections Oaklander has addressed against the date-theory.

Much current debate in the metaphysics of time is between A-theorists and B-theorists. Central to this debate is the assumption that time exists and that the task of metaphysics is to catalogue time’s features. Relatively little consideration has been given to an error theory about time. Since there is very little extant work on temporal error theory the goal of this paper is simply to lay the groundwork to allow future discussion of the relative merits of such a view. The (...) paper thus develops a conceptual framework from within which to evaluate claims about the actual existence, or not, of temporality as that notion appears in folk discourses about time, and from there to examine claims about the counterfactual existence, or not, of temporality so conceived. We subsequently apply this framework to three extant positions drawn from physics and metaphysics that deny the existence of time. We show that only one of these positions is a folk temporal error theory; that is, a view that denies the existence of time as that notion is operative in our everyday thought and talk. (shrink)

This paper motivates and develops a new theory of time: priority presentism. Priority presentism is the view according to which (i) only present entities exist fundamentally and (ii) past and future entities exist, but they are grounded in the present. The articulation of priority presentism is an exercise in applied grounding: it draws on concepts from the recent literature on ontological dependence and applies those concepts in a new way, to the philosophy of time. The result, as I will argue, (...) is an attractive position that can do much of the same work in satisfying our intuitions about time as presentism, but without the ontological cost. (shrink)
