In his recent book ‘Experiencing time’, Simon Prosser discusses a wide variety of topics relating to temporal experience, in a way that is accessible both to those steeped in the philosophy of mind, and to those more familiar with the philosophy of time. He forcefully argues for the conclusion that the B-theorist of time can account for the temporal appearances. In this article, I offer a chapter by chapter response.

Brains, it has recently been argued, are essentially prediction machines. They are bundles of cells that support perception and action by constantly attempting to match incoming sensory inputs with top-down expectations or predictions. This is achieved using a hierarchical generative model that aims to minimize prediction error within a bidirectional cascade of cortical processing. Such accounts offer a unifying model of perception and action, illuminate the functional role of attention, and may neatly capture the special contribution of cortical processing to (...) adaptive success. This target article critically examines this approach, concluding that it offers the best clue yet to the shape of a unified science of mind and action. Sections 1 and 2 lay out the key elements and implications of the approach. Section 3 explores a variety of pitfalls and challenges, spanning the evidential, the methodological, and the more properly conceptual. The paper ends (sections 4 and 5) by asking how such approaches might impact our more general vision of mind, experience, and agency. (shrink)

The target article sketched and explored a mechanism (action-oriented predictive processing) most plausibly associated with core forms of cortical processing. In assessing the attractions and pitfalls of the proposal we should keep that element distinct from larger, though interlocking, issues concerning the nature of adaptive organization in general.

English uses the horizontal spatial metaphors to express time (e.g., the good days ahead of us). Chinese also uses the vertical metaphors (e.g., 'the month above' to mean last month). Do Chinese speakers, then, think about time in a different way than English speakers? Boroditsky [Boroditsky, L. (2001). Does language shape thought? Mandarin and English speakers' conceptions of time. Cognitive Psychology, 43(1), 1-22] claimed that they do, and went on to conclude that 'language is a powerful tool in shaping habitual (...) thought about abstract domains' (such as time). By estimating the frequency of usage, we found that Chinese speakers actually use the horizontal spatial metaphors more often than the vertical metaphors. This offered no logical ground for Boroditsky's claim. We were also unable to replicate her experiments in four different attempts. We conclude that Chinese speakers do not think about time in a different way than English speakers just because Chinese also uses the vertical spatial metaphors to express time. (shrink)

The manifest image is teeming with activity. Objects are booming and buzzing by, changing their locations and properties, vivid perceptions are replaced, and we seem to be inexorably slipping into the future. Time—or at least our experience in time— seems a very turbulent sort of thing. By contrast, time in the scientist image seems very still. The fundamental laws of physics don’t differentiate between past and future, nor do they pick out a present moment that flows. Except for a minus (...) sign in the relativistic metric, there are few differences between the temporal and spatial coordinates in natural science. We seem to have, to echo another debate, an “explanatory gap” between time as we find it in experience and as we find it in science. Reconciling these two images of the world is the principal goal of philosophy of time. (shrink)

Time is a fundamental domain of experience. In this paper we ask whether aspects of language and culture affect how people think about this domain. Specifically, we consider whether English and Mandarin speakers think about time differently. We review all of the available evidence both for and against this hypothesis, and report new data that further support and refine it. The results demonstrate that English and Mandarin speakers do think about time differently. As predicted by patterns in language, Mandarin speakers (...) are more likely than English speakers to think about time vertically (with earlier time-points above and later time-points below).

Cognitive science has recently made some startling discoveries about temporal experience, and these discoveries have been drafted into philosophical service. We survey recent appeals to cognitive science in the philosophical debate over whether time objectively passes. Since this research is currently in its infancy, we identify some directions for future research.

Why is the future so different from the past? Why does the past affect the future and not the other way round? The universe began with the Big Bang - will it end with a `Big Crunch'? Now in paperback, this book presents an innovative and controversial view of time and contemporary physics. Price urges physicists, philosophers, and anyone who has ever pondered the paradoxes of time to look at the world from a fresh perspective, and throws fascinating new light (...) on some of the great mysteries of the universe.

As we navigate through life, we model time as flowing, the present as special, and the past as “dead.” This model of time—manifest time—develops in childhood and later thoroughly infiltrates our language, thought, and behavior. It is part of what makes a human life recognizably human. Yet if physics is correct, this model of the world is deeply mistaken. This book is about this conflict between manifest and physical time. The first half dives into the physics and philosophy to establish (...) the conflict’s existence; but it also argues that the claim that physics “spatializes” time is overstated. Rather, even relativity theory makes time special in deep and significant ways. The second half turns to psychology, biology, and more, seeking to understand why creatures like us develop manifest time. The novel picture that results is that manifest time is a natural reaction to the many cognitive and evolutionary challenges that we face. For subjects embedded in our circumstances, it makes sense to develop—even if fundamentally wrong. (shrink)

There seems to be a "what it is like" to the experience of the flow of time in any conscious activity of ours. In this paper, I argue that the feeling that time passes should be understood as a phenomenal modifier of our mental life, in roughly the same way as the blurred or vivid nature of a visual experience can be seen as an element of the experience that modifies the way it feels, without representing the world as being (...) in a certain way. I defend my positions against the deflationary view according to which the passing of time does not have a specific phenomenal character, and the representationalist view according to which the feeling of time passing is a feature of the representational content of our experience, like being red or yellow. (shrink)

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

According to the B-theory, the passage of time is an illusion. The B-theory therefore requires an explanation of this illusion before it can be regarded as fullysatisfactory; yet very few B-theorists have taken up the challenge of trying to provide one. In this paper I take some first steps toward such an explanation by first making a methodological proposal, then a hypothesis about a key element in the phenomenology of temporal passage. The methodological proposal focuses onthe representational content of the (...) element of experience by virtue of which time seems to pass. The hypothesis involves the claim that the experience of changeinvolves the representation of something enduring, rather than perduring, through any change. (shrink)

The nature of experience has been held to be a major reason for accepting the A-theory of time. I argue, however, that experience does not favour the A-theory over the B-theory; and that even if the A-theory were true it would not be possible to perceive the passage of time. The main argument for this draws on the constraint that a satisfactory theory of perception must explain why phenomenal characters map uniquely onto perceived worldly features. Thus, if passage is perceived, (...) it must be explained what makes one phenomenal character rather than another a perception of passage; and it must also be explained why that phenomenal character is a perception of passage rather than of some other feature of the world. I argue that no such explanation can be given, and consequently that passage cannot be perceived. I conclude that the A-theory is rendered unintelligible, and should therefore be rejected. (shrink)

This is an expanded and revised discussion of the argument briefly put forward in my 'A New Problem for the A-Theory of Time', where it is claimed that it is impossible to experience real temporal passage and that no such phenomenon exists. In the first half of the paper the premises of the argument are discussed in more detail than before. In the second half responses are given to several possible objections, none of which were addressed in the earlier paper. (...) There is also some discussion of some related epistemic arguments against the passage of time given by Huw Price and David Braddon-Mitchell along with objections raised against them recently by Tim Maudlin and Peter Forrest respectively. (shrink)

The question I want to explore is whether experience supports an antireductionist ontology of time, that is, whether we should take it to support an ontology that includes a primitive, monadic property of nowness responsible for the special feel of events in the present, and a relation of passage that events instantiate in virtue of literally passing from the future, to the present, and then into the past.

Across cultures people construct spatial representations of time. However, the particular spatial layouts created to represent time may differ across cultures. This paper examines whether people automatically access and use culturally specific spatial representations when reasoning about time. In Experiment 1, we asked Hebrew and English speakers to arrange pictures depicting temporal sequences of natural events, and to point to the hypothesized location of events relative to a reference point. In both tasks, English speakers (who read left to right) arranged (...) temporal sequences to progress from left to right, whereas Hebrew speakers (who read right to left) arranged them from right to left, replicating previous work. In Experiments 2 and 3, we asked the participants to make rapid temporal order judgments about pairs of pictures presented one after the other (i.e., to decide whether the second picture showed a conceptually earlier or later time-point of an event than the first picture). Participants made responses using two adjacent keyboard keys. English speakers were faster to make “earlier” judgments when the “earlier” response needed to be made with the left response key than with the right response key. Hebrew speakers showed exactly the reverse pattern. Asking participants to use a space-time mapping inconsistent with the one suggested by writing direction in their language created interference, suggesting that participants were automatically creating writing-direction consistent spatial representations in the course of their normal temporal reasoning. It appears that people automatically access culturally specific spatial representations when making temporal judgments even in nonlinguistic tasks. (shrink)

We use the hierarchical nature of Bayesian perceptual inference to explain a fundamental aspect of the temporality of experience, namely the phenomenology of temporal flow. The explanation says that the sense of temporal flow in conscious perception stems from probabilistic inference that the present cannot be trusted. The account begins by describing hierarchical inference under the notion of prediction error minimization, and exemplifies distrust of the present within bistable visual perception and action initiation. Distrust of the present is then discussed (...) in relation to previous research on temporal phenomenology. Finally, we discuss how there may be individual differences in the experience of temporal flow, in particular along the autism spectrum. The resulting view is that the sense of temporal flow in conscious perception results from an internal, inferential process. (shrink)

I examine some recent claims put forward by L. A. Paul, Barry Dainton and Simon Prosser, to the effect that perceptual experiences of movement and change involve an (apparent) experience of ‘passage’, in the sense at issue in debates about the metaphysics of time. Paul, Dainton and Prosser all argue that this supposed feature of perceptual experience – call it a phenomenology of passage – is illusory, thereby defending the view that there is no such a thing as passage, conceived (...) of as a feature of mind-independent reality. I suggest that in fact there is no such phenomenology of passage in the first place. There is, however, a specific structural aspect of the phenomenology of perceptual experiences of movement and change that can explain how one might mistakenly come to the belief that such experiences do involve a phenomenology of passage.

In this paper we examine how English and Mandarin speakers think about time, and we test how the patterns of thinking in the two groups relate to patterns in linguistic and cultural experience. In Mandarin, vertical spatial metaphors are used more frequently to talk about time than they are in English; English relies primarily on horizontal terms. We present results from two tasks comparing English and Mandarin speakers’ temporal reasoning. The tasks measure how people spatialize time in three-dimensional space, including (...) the sagittal (front/back), transverse (left/right), and vertical (up/down) axes. Results of Experiment 1 show that people automatically create spatial representations in the course of temporal reasoning, and these implicit spatializations differ in accordance with patterns in language, even in a non-linguistic task. Both groups showed evidence of a left-to-right representation of time, in accordance with writing direction, but only Mandarin speakers showed a vertical top-to-bottom pattern for time (congruent with vertical spatiotemporal metaphors in Mandarin). Results of Experiment 2 confirm and extend these findings, showing that bilinguals’ representations of time depend on both long-term and proximal aspects of language experience. Participants who were more proficient in Mandarin were more likely to arrange time vertically (an effect of previous language experience). Further, bilinguals were more likely to arrange time vertically when they were tested in Mandarin than when they were tested in English (an effect of immediate linguistic context). (shrink)

If, as the new tenseless theory of time maintains, there are no tensed facts, then why do our emotional lives seem to suggest that there are? This question originates with Prior’s ‘Thank Goodness That’s Over’ problem, and still presents a significant challenge to the new B-theory of time. We argue that this challenge has more dimensions to it than has been appreciated by those involved in the debate so far. We present an analysis of the challenge, showing the different questions (...) that a B-theorist must answer in order to meet it. The debate has focused on the question of what is the object of my relief when an unpleasant experience is past. We outline the prevailing response to this question. The additional, and neglected, questions are, firstly—‘Why does the same event elicit different emotional responses from us depending on whether it is in the past, present, or future?’ And secondly—‘Why do we care more about proximate future pain than about distant future pain?’ We give B-theory answers to these questions, which appeal to evolutionary considerations.

Ross P. Cameron argues that the flow of time is a genuine feature of reality. He suggests that the best version of the A-Theory is a version of the Moving Spotlight view, according to which past and future beings are real, but there is nonetheless an objectively privileged present. Cameron argues that the Moving Spotlight theory should be viewed as having more in common with Presentism than with the B-Theory. Furthermore, it provides the best account of truthmakers for claims about (...) what was or will be the case. Cameron goes on to defend an account of the open future, and argues that this is a better account than that available to the Growing Block theory. (shrink)

Time - relentless, ever-present but intangible and the single element over which human beings have no absolute control - has long proved a puzzle. The author examines the phenomenon of time and asks such fascinating questions as how time impinges on people, to what extent our awareness of time is culturally conditioned, how societies deal with temporal problems and whether time can be considered a `resource' to be economized. More specifically, he provides a consistent and detailed analysis of theories put (...) forward by a number of thinkers such as Durkheim, Evans-Pritchard, Lévi-Strauss, Geertz, Piaget, Husserl and Bourdieu. His discussion encompasses four main approaches in time research, namely developmental psychology, symbolic anthropology `economic' theories of time in social geography and, finally, phenomenological theories. The author concludes by presenting his own model of social/cognitive time, in the light of these critical discussions of the literature. (shrink)

A Brief History of the Philosophy of Time is a concise and accessible survey of the history of philosophical and scientific developments in understanding time and our experience of time. It discusses prominent ideas about the nature of time, plus many subsidiary puzzles about time, from the classical period through the present.

Michael Tooley presents a major new philosophical theory of the nature of time, offering a powerful alternative to the traditional "tensed" and recent "tenseless" accounts of time. He argues for a dynamic conception of the universe, in which past, present, and future are not merely subjective features of experience. He claims that the past and the present are real, while the future is not. Tooley's approach accounts for time in terms of causation. He therefore claims that the key to understanding (...) the dynamic nature of the universe is to understand the nature of causation. Time, Tense, and Causation is a landmark treatment of one of the oldest and most perplexing intellectual problems, and will be fascinating reading for anyone interested in the character of time.

LET ME BEGIN this inquiry with the simple but fundamental fact that the flow of time, or passage, as it is also known, is given in experience, that it is as indubitable an aspect of our perception of the world as the sights and sounds that come in upon us, even though it is not the peculiar property of a special sense. Consider, by way of illustration, that I am now sitting at the desk in my study. This particular event (...) was not present at any earlier time, nor will it be present shortly as I become involved in other activities. The present, as I experience it, is regularly associated with later and later events. It does not hop about capriciously from here to a later time, to a previous time, and then to a much later time, or trace out some other such indiscriminate pattern; instead I find it always in association with the next moment, and as I look backward and inward, so to speak, I find that the prior moment was present and that this next-later moment is present. Quite often this condition is expressed by means of imagery. We are asked to envision either a moving present racing along a fixed track of moments or events from earlier to later, or alternatively a fixed present through which stream a series of moments or events, first the earlier and then the later ones. One is in truth hard-pressed to find references to passage which do not employ quasi-poetical tropes and metaphors, and while these do help in some sense to say what we mean, great caution is required when handling them because of their ready tendency to draw us away from the actual phenomenon requiring explanation.

Marketers use autobiographical advertising as a means to create nostalgia for their products. This research explores whether such referencing can cause people to believe that they had experiences as children that are mentioned in the ads. In Experiment 1, participants viewed an ad for Disney that suggested that they shook hands with Mickey Mouse as a child. Relative to controls, the ad increased their confidence that they personally had shaken hands with Mickey as a child at a Disney resort. The (...) increased confidence could be due to a revival of a true memory or the creation of a new, false one. In Experiment 2, participants viewed an ad for Disney that suggested that they shook hands with an impossible character (e.g., Bugs Bunny). Again, relative to controls, the ad increased confidence that they personally had shaken hands with the impossible character as a child at a Disney resort. The increased confidence is consistent with the notion that autobiographical referencing can lead to the creation of false or distorted memory. ᭧ 2002 John Wiley & Sons, Inc. (shrink)
