What is the relation between metaphysical and psychological insights into temporal asymmetries? This chapter examines that question on the basis of a case study concerning the temporal Doppler effect. It argues for the following claims: (1) Caruso et al.’s talk of a subjective movement through time seems best interpreted as concerning our longer term cognitive relationship to time; (2) both A- and B-theoretic interpretations of their discussion are viable as interpretations; (3) if combined with Priorean arguments for the A-theory, it takes some work to ensure the A-theoretic interpretation respects the constraint that objective temporal distance cannot directly influence psychological outcomes; and (4) a third, less metaphysically loaded interpretation may be preferable to both the A- and the B-theoretic ones.

Ismael’s self-reference view is an intriguing addition to the philosophy of time landscape. This commentary offers an interpretation of the view. I argue for two claims. The first is that for Ismael, the explanans (namely self-reference + the thermodynamic gradient) is partly fulfilling the role of giving meaning to a key part of the explanandum (namely Agents’ sense of the future as coming into being). That is, Ismael is partly (re-)interpreting ‘Becoming’ as denoting self-reference. The second is that the self-reference view centrally builds on Ismael’s previous work on tenseless, relativity-friendly passage and the idea that Heraclitians and Parmenideans are both right. In closing, I briefly comment on an unsolved challenge for the view.

ABSTRACT This article is a response to 'Fear of death and the symmetry argument', in this issue. In that article, the author discusses the above Lucretian symmetry argument, and proposes a view that justifies the existing asymmetry in our attitudes towards birth and death. I begin by distinguishing this symmetry argument from a different one, also loosely inspired by Lucretius, which also plays a role in the article. I then describe what I take to be the author's solution to the original symmetry argument and explain why I am unpersuaded by it.

Much of the literature on religious fictionalism has emphasized that religious fictionalists employing a theistic fiction cannot just leave evil out of the fiction, and that on the contrary, they face worries that very closely parallel the worries raised by the problem of evil. This article argues that when religious fictionalism is construed most charitably, these worries do not arise. It explores three fictionalist approaches to evil (Excision, Completeness, and Inconsistency), shows that each can serve religious fictionalist ends, and recommends a pluralist stance towards them.

Hodroj, Latham, and Miller use X-phi methods to investigate why people tend to represent time as dynamic (i.e., as (robustly) passing), even though, as deflationists maintain, they do not perceive time as passing. More specifically, what the authors investigate is the hypothesis that people believe time is dynamic because they believe the future is objectively open (moving open future hypothesis, MOFH); they find no evidence for the relevant associations. They conclude that a different (temporally aperspectival replacement, TARH) hypothesis based on non-X-phi proposals by Hoerl (Hoerl, 2018) and Sattig (Sattig, 2019a, 2019b) is worth investigating further by X-phi methods. The authors’ empirical methodology in this and other papers is especially welcome given widespread suspicion of purely a priori methods (those of “armchair” or “free-range” metaphysics). Yet, it is not always obvious how best to interpret these kinds of findings. In this reply, I express some worries about the paper’s framing regarding its empirical findings, including their relation to the debate about temporal perception. I also consider whether the responses recorded in these surveys are best interpreted as indicating that people stably (even tacitly) represent time in ways articulated by metaphysicians. I take it to be another facet of the value of X-phi work on time that it raises these interpretative (and related metametaphysical) issues, whose relevance to disputes over proper methodology in the philosophy of time is easy to overlook.

This article introduces the reader to contemporary philosophical research on God and time, without presupposing any familiarity with either philosophy of religion or philosophy of time. To start with, aspects of the topic are compared to some structurally similar ideas in secular philosophical thought about time and ethics. The article then introduces timeless versus temporal conceptions of eternity and discusses positions intending to combine elements of both. There is a brief interlude on relevant background in temporal metaphysics regarding A- and B-theories. The final two sections then examine recent developments in the timeless and temporal camps, with a particular emphasis on the role that temporal metaphysics is playing in discussions of the timeless approach.

Present-bias is the preference, all else being equal, for positive events to be located in the present rather than the non-present, and for negative events to be located in the non-present rather than the present. Very little attention has been given to present-bias in the contemporary literature on time biases. This may be because it is often assumed that present-bias is not a distinctive psychological kind; that what explains people’s being present-biased is just what explains them displaying various other time-biases. According to this view, there is no need to investigate present-bias independently of investigating these other biases, since present-bias is really just a manifestation of these other biases. We call this the manifestation thesis. We take up the question of whether the manifestation thesis is true, and argue that it is not. Thus, by failing to investigate present-bias in its own right we are failing fully to understand the spectrum of ways in which people display time biases. In turn, we suggest, this may have implications for the ways we evaluate whether present-bias is rationally permissible.

What is the relation between metaphysical and psychological insights into temporal asymmetries? This chapter examines that question on the basis of a case study concerning the temporal Doppler effect (Caruso, Van Boven, Chin, & Ward, 2013). Caruso et al. propose that future events seem closer than past ones at an equal objective temporal distance because we experience subjective movement through time. I explore ways of interpreting their discussion in the light of the metaphysical debate between A- and B-theorists over whether time really passes and whether the future is genuinely ‘open’ while the past is ‘fixed’. I argue for the following claims: (1) Caruso et al.’s talk of a subjective movement through time seems best interpreted as concerning our longer term cognitive relationship to time; (2) both A- and B-theoretic interpretations of their discussion are viable as interpretations; (3) if combined with Priorean arguments for the A-theory, it takes some work to make sure the A-theoretic interpretation respects Van Boven and Caruso’s constraint that the objective temporal distance cannot directly influence psychological outcomes without influencing psychological intermediaries; and (4) a third, less metaphysically loaded interpretation may be preferable to both the A- and the B-theoretic ones.

Craig Callender’s What Makes Time Special? (OUP 2017) advocates and practices an innovative, thoroughly interdisciplinary approach to philosophical questions about time and temporal features of our lives. Grappling with it is of intrinsic philosophical interest; it is also part of responding to the methodological invitation the book issues to philosophers of time. This paper is motivated by the wish to clarify WMTS’s philosophical underpinnings. The main claim of the paper is that WMTS relies on an ambiguity between rejecting the A-theory versus B-theory debate, and endorsing a position within that debate. This ambiguity leads to a somewhat unstable position on how a key feature of manifest time, namely our sense of time as flowing, arises from physical time. The paper ends with a suggestion for how to resolve the ambiguity, in a way that is in line with the gist of Callender’s overall vision for the field.

I examine the relation between naturalistically motivated and other critiques of grounding and similar critiques of the contrast between A- and B-theoretic views of time. I argue that even the combined dialectical upshot of nonunity objections in the latter case is not what it is in the former. I sympathetically discuss the objection that the notion of grounding is not intelligible and part of ‘esoteric’ metaphysics; this objection turns out to be just as serious in the case of the A/B contrast. I then consider whether grounding is needed to draw the A/B contrast in the first place and answer this question in the negative. Finally, I comment on the costs of esotericism in both cases.

Fabrice Correia and Sven Rosenkranz’s book Nothing to Come: a Defence of the Growing Block Theory of Time offers an incredibly rich and skillful defense of the growing block theory (GBT), a view of time that arguably has much intuitive appeal, and which has been under attack from many sides. Nonetheless, I have to report that the book’s tense-logical course of treatment has not worked for me; I still struggle with making sense of the GBT. This article begins by drawing out some implications of the book’s set up. First, the notion of existence in play here is not interpretable on the basis of ordinary usage. Second, it would be a mistake to take the tense-logical framework to have any metaphysical significance. I then articulate two main worries about their version of the GBT. The first worry takes a familiar shape: it is just hard to see how their view is dynamic in the relevant sense. The second worry is that the topic seems to have been changed. C&R’s logical system helps itself to key notions whose intended interpretation includes a solution to every metaphysical puzzle about the GBT, so that these puzzles are not so much addressed as enshrined in a formal system. That is, their view seems to answer the question of how language should behave, if the GBT were (somehow) true.

This paper investigates the connection between temporal attitudes (attitudes characterised by a concern (or lack thereof) about future and past events), beliefs about temporal ontology (beliefs about the existence of future and past events) and temporal preferences (preferences regarding where in time events are located). Our aim is to probe the connection between these preferences, attitudes, and beliefs, in order to better evaluate the normative status of these preferences. We investigate the hypothesis that there is a three-way association between (a) being present-biased (that is, preferring that positive events are located in the present, and negative events are located in the non-present), (b) believing that past and future events do not exist and (c) tending to have present-focused rather than non-present-focused temporal attitudes. We find no such association. This suggests that insofar as temporal preferences and temporal attitudes are connected to the ways we represent time, they are not connected to the ways we represent temporal ontology; rather, they are more likely connected to the ways we represent relative movement in, or of, time. This has important consequences for, first, explaining why we exhibit these preferences and, second, for their normative evaluation.

This chapter discusses some aspects of the relation between temporal experience and the A versus B debate. To begin with, I provide an overview of the A versus B debate and, following Baron et al. (2015), distinguish between two B-theoretic responses to the A- theoretic argument from experience, veridicalism and illusionism. I then argue for veridicalism over illusionism, by examining our (putative) experiences as of presentness and as of time passing. I close with some remarks on the relation between veridicalism and a deflationary view of the A versus B debate. I suggest that the deflationary view can provide further support for veridicalism.

Does time seem to pass, even though it doesn’t, really? Many philosophers think the answer is ‘Yes’—at least when ‘time’s passing’ is understood in a particular way. They take time’s passing to be a process by which each time in turn acquires a special status, such as the status of being the only time that exists, or being the only time that is present. This chapter suggests that, on the contrary, all we perceive is temporal succession, one thing after another, a notion to which modern physics is not inhospitable. The contents of perception are best described in terms of ‘before’ and ‘after’, rather than ‘past’, ‘present, and ‘future’.

This chapter explores some of the relations between Quine’s and Carnap’s metaontological stances on the one hand, and contemporary work in the metaphysics of time, on the other. Contemporary metaphysics of time, like analytic metaphysics in general, grew out of the revival of the discipline that Quine’s critique of the logical empiricists (such as Carnap) made possible. At the same time, the metaphysics of time has, in some respects, strayed far from its Quinean roots. This chapter examines some likely Quinean and Carnapian reactions to elements of the contemporary scene.

The God of Western religion is said to be eternal. But what does that mean? Is God somehow beyond time, living a life that does not involve one thing after another? Or is God's relationship to time much more like ours, so that God's eternality just consists in there being no time at which God doesn't exist? Even for non-believers, these issues have interesting implications for the relation between historical and scientific findings on the one hand, and religion on the other. This Element introduces the reader to the requisite metaphysical background, and then examines reasons for and against thinking of God as timeless.

Usually, the B-theory of time is taken to involve the claim that time does not, in reality, pass; after all, on the B-theory, nothing really becomes present and then more and more past, times do not come into existence successively, and which facts obtain does not change. For this reason, many B-theorists have recently tried to explain away one or more aspect(s) of experience that they and their opponents take to constitute an experience of time as passing. In this paper, I examine three prominent proposals of this kind and argue that, though intriguing, the proposals undermine, to some extent, the assumption that there is an element of experience that B-theorists need to take to be illusory.

This article is a response to Clifford Williams’s claim that the debate between A- and B theories of time is misconceived because these theories do not differ. I provide some missing support for Williams’s claim that the B-theory includes transition, by arguing that representative B-theoretic explanations for why we experience time as passing (even though it does not) are inherently unstable. I then argue that, contra Williams, it does not follow that there is nothing at stake in the A- versus B debate.

Temporal ontology is the part of ontology involving the rival positions of presentism, eternalism, and the growing block theory. While this much is clear, it’s surprisingly difficult to elucidate the substance of the disagreement between presentists and eternalists. Certain events happened that are not happening now; what is it to disagree about whether these events exist? In spite of widespread suspicion concerning the status and methods of analytic metaphysics, skeptics’ doubts about this debate have not generally been heeded, neither by metaphysicians, nor by philosophers of physics. This paper revisits the question in the light of prominent elucidation attempts from both camps. The upshot is that skeptics were right to be puzzled. The paper then explores a possible re-interpretation of positions in temporal ontology that links it to normative views about how we should live as temporal beings.

In this paper I revisit a dispute between Mikel Burley and Robin Le Poidevin about whether or not the B-theory of time can give its adherents any reason to be less afraid of death. In ‘Should a B-theoretic atheist fear death?’, Burley argues that even on Le Poidevin’s understanding of the B-theory, atheists shouldn’t be comforted. His reason is that the prevalent B-theoretic account of our attitudes towards the past and future precludes treating our fear of death as unwarranted. I examine his argument and provide a tentative defense of Le Poidevin. I claim that while Burley rightly spots a tension with a non-revisionary approach to our ordinary emotional life, he doesn’t isolate the source of that tension. The real question is how to understand Le Poidevin’s idea that on the B-theory, we and our lives are ‘eternally real’. I then suggest that there is a view of time that does justice to Le Poidevin’s remarks, albeit a strange one. The view takes temporal relations to be quasi-spatial and temporal entities to exist in a totum simul.
