It is widely held that episodic memory is constitutively connected with space and time. In particular, many contend that episodic memory constitutively has spatial and/or temporal content: for instance, necessarily representing a spatial scene, or when a given event occurred, or at the very minimum that it occurred in the past. Here, I critically assess such claims. I begin with some preparatory remarks on the nature of episodic memory. I then ask: How, if at all, is episodic memory constitutively spatial? (...) And, how, if at all, is episodic memory constitutively temporal? In answer, I argue that episodic memory need not have any spatial content, nor (in any substantial sense) need it represent when its events occur, nor even that they occur in the past. Instead, only a relatively modest connection holds between episodic memory and time in virtue of the temporal structure of its objects. Finally, I critically assess whether considerations concerning the organization and encoding of episodic memory in creatures like us provide stronger reason to posit a constitutive link between our episodic memories and space or time.

A prominent view holds that perception and memory are distinguished at least partly by their temporal orientation: Perception functions to represent the present, while memory functions to represent the past. Call this view perceptual presentism. This chapter critically examines perceptual presentism in light of contemporary perception science. I adduce evidence for three forms of perceptual sensitivity to the past: (i) shaping perception by past stimulus exposure, (ii) recruitment of mnemonic representations in perceptual processing, and (iii) perceptual representation of present objects (...) as possessing past properties. I argue that forms (i) and (ii) are consistent with perceptual presentism, while form (iii) poses a genuine threat to the view. While the empirical case for form (iii) remains inconclusive, I suggest that the most serious challenges to perceptual presentism derive from representations that integrate mnemonic and present-tensed elements in the performance of canonical perceptual functions, such as perceiving object continuity over time.

Philosophers have usually approached the concept of timing of experiences by addressing the question how the experiences of temporal phenomena can be explained. As a result, the issue of timing has been addressed in two different ways. The first, similar to the questions posed in sciences, concerns the relationship between the experienced time of events and the objective time of events. The second approach is more specific to philosophers’ debates, and concerns the phenomenology of experiences: how is the apparent temporal (...) structure of experiences constituted? In regard to both questions, this article shows why and how philosophers’ views differ from those held by most scientists. To conclude, I present a combination of views that is not only compatible with that of scientists, but also addresses the problems that engage philosophers. (shrink)

Temporal dynamists typically hold that it seems to us as though time robustly passes, and that its seeming so is explained by the fact that time does robustly pass. Temporal non-dynamists hold that time does not robustly pass. Some non-dynamists nevertheless hold that it seems as though it does: we have an illusory phenomenal state whose content represents robust passage. Call these phenomenal passage illusionists. Other non-dynamists argue that the phenomenal state in question is veridical and represents something other than (...) robust passage. Call this the veridical passage-less view. This paper argues in favour of the latter view over the former, by arguing that we should reject passage illusionism. (shrink)

In first personal accounts of the experience of grief, it is often described as disrupting the experience of time. This aspect of the experience has gained more attention in recent discussions, but it may nonetheless strike some as puzzling. Grieving subjects do, after all, still perceptually experience motion, change, and succession, and they are typically capable of orienting themselves in time and accurately estimating durations. As such, it is not immediately obvious how we ought understand the claim that grief disrupts (...) the experience of time. In the present discussion I suggest that we can shed light on this aspect of the experience of grief by distinguishing between three temporal perspectives that experiencing (human) subjects typically occupy: the perceptual, the agential, and the narrative. Appeal to these three temporal perspectives helps to clarify the phenomenology of grief; it reveals a way in which grief can disrupt the experience of time; and it can also help us to analyse pre-existing issues in the literature on grief.

Integrated information theory of consciousness proposes an identity between its causal structure and phenomenology. Through this assertion, IIT aims to explain consciousness by prioritizing first-person experience. However, despite its phenomenology-first stance, developments in IIT have overlooked temporality. As such, we argue that at present IIT’s phenomenological analysis is incomplete. In this critique, we show how IIT takes a non-identical illusionist stance towards the experiences of continuity, flow, and extent of our experiences. Moreover, in isolating temporal grains of experience to a (...) single timescale, IIT misses out on capturing the multi-scale nested nature of temporal phenomena. Hence, we contend that IIT needs an axiom for time, through which its causal structure can be refined to account for temporal experiences. Here, we propose an axiom to address these concerns. We conclude by discussing how IIT may need to be revised if our concerns hold true. (shrink)

Panpsychists aspire to explain human consciousness, but can they also account for the physical world? In this paper, I argue that proponents of a popular form of panpsychism cannot. I pose a new challenge against this form of panpsychism: it faces an explanatory gap between the fundamental experiences it posits and some physical entities. I call the problem of explaining the existence of these physical entities within the panpsychist framework “the missing entities problem.” Spacetime, the quantum state, and quantum gravitational (...) entities constitute three explanatory gaps as instances of the missing entities problem. Panpsychists are obliged to solve all instances of the missing entities problem; otherwise, panpsychism cannot be considered a viable theory of consciousness. (shrink)

Experiences of motion and change are widely taken to have a ‘flow-like’ quality. Call this ‘temporal qualia’. Temporal qualia are commonly thought to be central to the question of whether time objectively passes: (1) passage realists take temporal passage to be necessary in order for us to have the temporal qualia we do; (2) passage antirealists typically concede that time appears to pass, as though our temporal qualia falsely represent time as passing. I reject both claims and make the case (...) that passage-talk plays no useful explanatory role with respect to temporal qualia, but rather obfuscates what the philosophical problem of temporal qualia is. I offer a ‘reductionist’ account of temporal qualia that makes no reference to the concept of passage and argue that it is well motivated by empirical studies in motion perception. (shrink)

The pacemaker-accumulator model provides a framework in which the results of different duration estimation tasks are commonly accounted for. Nevertheless, the model remains abstract and it does not provide proper explanations nor predictions for duration estimations in various experimental set-ups. This paper aims to address these shortcomings by explicating an experiential pacemaker-accumulator model that supplements the standard pacemaker-accumulator model with two claims. Both of them concern the role that experiences play in duration estimation tasks and are also partly supported by (...) studies not directly related to duration estimation. First, the internal responses based on which the switch between the pacemaker and the accumulator operates are the same as the neural processes that realize conscious access to experiences. Second, the processes that realize the experiences of stimuli realize the function of the pacemaker. By supplementing the standard pacemaker-accumulator model with these claims, the model affords proper explanations for the systematic errors and empirically testable predictions in duration estimations tasks. One likely consequence of the model is that the experience of duration and the duration of experience can differ. (shrink)

Philosophers frequently comment on the intimate connection there is between something’s being present in perceptual experience and that thing’s being, or at least appearing to be, temporally present. Yet, there is relatively little existing work that goes beyond asserting such a connection and instead examines its specific nature. In this paper, I suggest that we can make progress on the latter by looking at two more specific debates that have hitherto been conducted largely isolation from each other: one about the (...) nature of conscious experience and one about the nature of time itself. The first concerns the extent to which the temporal properties of experience form an exception to the transparency of experience, meaning that introspection can provide support for one particular view of how experience itself is structured temporally; the second concerns the question as to whether there is something about experience that gives us grounds for thinking that the present is somehow metaphysically special. As I argue, the idea of a connection between experiential presence and temporal presence plays a key background role in each of these debates. Yet it can also, in each of them, be seen to draw one side towards making claims that are supposed to express an important truth but are at the same time, on the face of it, self-contradictory. In each case, resolving what it actually is that these claims are trying to get at turns on recognizing a distinctive feature of perceptual experience, which I refer to as its lack of temporal viewpointedness. Recognising this feature also helps in making sense of what the issues at stake actually are in the intuition of an intimate connection between experiential presence and temporal presence. (shrink)

A central debate in the current philosophical literature on temporal experience is over the following question: do temporal experiences themselves have a temporal structure that mirrors their temporal contents? Extensionalists argue that experiences do have a temporal structure that mirrors their temporal contents. Atomists insist that experiences don’t have a temporal structure that mirrors their contents. In this paper, I argue that this debate is misguided. Both atomism and extensionalism, considered as general theories of temporal experience, are false, since temporal (...) experience is not a single undifferentiated phenomena as both theories require. I argue for this conclusion in two steps. First, I show that introspection cannot settle the debate. Second, I argue that the neuroscientific evidence is best read as revealing a host of mechanisms involved in temporal perception - some admitting of an extensionalist interpretation while others admitting only of an atomistic interpretation. As a result, neither side of the debate wins. (shrink)

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

As far as our experience goes, we live in a dynamic present. Those two phenomenal features of experience—presentness and dynamism—are obviously connected. However, how they are connected is not obvious at all. In this paper, I criticise the view according to which the former can explain the latter, which I call sophisticated representationalism. My criticism will be based on an ambiguity in the notion of tense found in the philosophical literature, that between the perspectival understanding and the dynamic understanding of (...) tenses. The distinction is not just of independent interest, but it has a role in providing indirect evidence for the claim that the feeling of passage of time should be understood in non-representationalist terms. (shrink)

The nature of temporal experience is typically explained in one of a small number of ways, most are versions of either retentionalism or extensionalism. After describing these, I make a distinction between two kinds of temporal character that could structure temporal experience: A-ish contents are those that present events as structured in past/present/future terms, and B-ish contents are those that present events as structured in earlier-than/later-than/simultaneous-with relations. There are a few exceptions, but most of the literature ignores this distinction, and (...) silently assumes temporal experience is A-ish. I then argue that temporal character is not scale invariant, but rather that temporal experience is A-ish at larger scales, and B-ish at smaller scales. I then point out that this scale non-invariance opens the possibility of hybrid views. I clarify my own view as a hybrid view, according to which temporal experience is B-ish at small scales – and at this scale my trajectory estimation model applies – but A-ish at larger scales, and at the larger scale my TEM does not apply. I then motivate this hybrid position by first defending it against arguments that have tried to show that the TEM is untenable. Since the hybrid view has TEM as its small-scale component, it must address this objection. I then put pressure on the main alternative account, extentionalism, by showing that its proponents have not adequately dealt with the problem of temporal illusions. The result is a new theory motivated by i) explaining its virtues, ii) showing that objections to it can be met, and iii) showing that objections to its main competitors have not been met. (shrink)

If God exists atemporally, could God still be temporally conscious? This article aims to clarify a conceptual space for a divine temporal mode of consciousness under the traditional assumption that God exists atemporally. I contend that an atemporally existing and conscious God – by the divine nature, and not just the human nature in Christ – could also be conscious of the temporal world – and indeed, all possible temporal worlds – through a temporal mode that is akin to human (...) temporal consciousness, albeit exempt from its limitations. I submit that although (a) God exists atemporally (ontological atemporalism), (b) God could be both temporally and atemporally conscious (bimodalism of divine consciousness), and (c) these two modes of consciousness could be unified in an absolute divine consciousness without incurring schizophrenia-like problems (unity of bimodal divine consciousness).

While we perceive events in our environment through multiple sensory systems, we nevertheless perceive all of these events as occupying a single unified timeline. Time, as we perceive it, is unified. I argue that existing accounts of the perceived unity of time fail. Instead, the perceived unity of time must be constructed by integrating our initially fragmented timekeeping capacities. However, existing accounts of multimodal integration do not tell us how this might occur. Something new is needed. I finish the paper (...) by articulating the hurdles that must be overcome to provide an account of the perceived unity of time. (shrink)

We seem to experience time as flowing. Yet according to the leading metaphysical picture of time, the block-universe theory, time in fact does not flow. Block-lovers typically react to this apparent tension by unhitching the sense of flow in our temporal experience from temporal reality, holding that temporal experience is systematically illusory. I shall develop a new block-friendly account of the sense of flow, which preserves a match of temporal experience and temporal reality. According to this account, the sense of (...) flow arises from higher-order temporal experience. (shrink)

A number of contemporary philosophers of mind have brought considerations from the study of aspect to bear on the ontological question how perceptual experiences persist over time. But, apart from rare exceptions, relatively little attention has been devoted to assess whether the way we talk about perceptual occurrences is of any relevance for discussions of ontological matters in general, let alone discussions about the ontological nature of perception. This piece examines whether considerations derived from the study of lexical aspect have (...) a significant bearing on what ontological views of perception we should endorse: I shall argue that such aspectual considerations are in fact of very little use for settling the relevant ontological issue. (shrink)

In this thesis I present a phenomenological investigation of our experience of time – of things as they fall within time – and suggest that something important goes missing in recent debates. This is the notion of a point of view. I believe that articulating the sense in which we have a point of view in time, and what this is a point of view upon, is crucial to an account of how things are for an experiencing subject. In the (...) first chapter, I elucidate the specious present. I argue that theorists appeal to the specious present under two guises without explicitly distinguishing between them; yet these two conceptions are not identical, while one entails the other the reverse is not true. In the second chapter I defend an appeal to the specious present against proponents of what I refer to as snapshot models of temporal experience. I argue that perceptual experience minimally presents something of some non-zero temporal extent as such. In the third chapter I discuss how we are to characterise experience over intervals of time of a greater extent than the specious present. I offer a proposal on which a subject is invariably presented with a positive temporal extent, with this interval marking the partition between the past and the future for the subject. In the fourth chapter I compare and contrast our experience of objects and events, and our experiential point of view in space and in time. Among other things, I argue that getting right how things are for the subject requires an appeal to the subject’s asymmetrical awareness of times either side of the specious present. In fifth and final chapter I demonstrate that appeal to an experiencing subject’s tensed temporal perspective can explain the sense in which time seems to pass. (shrink)

Although it has long been known that time is a cue to causation, recent work with adults has demonstrated that causality can also influence the experience of time. In causal reordering (Bechlivanidis & Lagnado, 2013, 2016) adults tend to report the causally consistent order of events, rather than the correct temporal order. However, the effect has yet to be demonstrated in children. Across four pre-registered experiments, 4- to 10-year-old children (N=813) and adults (N=178) watched a 3-object Michotte-style ‘pseudocollision’. While in (...) the canonical version of the clip object A collided with B, which then collided with object C (order: ABC), the pseudocollision involved the same spatial array of objects but featured object C moving before object B (order: ACB), with no collision between B and C. Participants were asked to judge the temporal order of events and whether object B collided with C. Across all age groups, participants were significantly more likely to judge that B collided with C in the 3-object pseudocollision than in a 2-object control clip (where clear causal direction was lacking), despite the spatiotemporal relations between B and C being identical in the two clips (Experiments 1—3). Collision judgements and temporal order judgements were not entirely consistent, with some participants—particularly in the younger age range—basing their temporal order judgements on spatial rather than temporal information (Experiment 4). We conclude that in both children and adults, rather than causal impressions being determined only by the basic spatial-temporal properties of object movement, schemata are used in a top-down manner when interpreting perceptual displays.

The hyper-Russellian skeptic is someone who thinks that only one of all your experiences was, is, and will ever be conscious. Which one? The very one you are having now. Before you were always a zombie, and you will be a zombie for ever after. In the present literature on the metaphysics of passage of time, there is disagreement on whether our feeling that time passes — the “dynamic flavor” of our ordinary experience — provides support to the A-theory, that (...) is, the thesis that the passage of time is an objective feature of reality. Lately, several philosophers have argued against this idea. In this paper I want to push this line of reasoning further by exploiting the hyper-Russellian scenario against the A-theory of time.

Temporal experiences, according to retentionalism, essentially have temporally extended contents: contents which represent distinct events at distinct temporal locations, and some of their temporal relations. This means, retentionalists insist, that temporal experiences themselves needn’t be extended in time: only their contents are. The paper reviews an experiment by Moutoussis and Zeki, which demonstrates a colour-motion visual asynchrony (§2): information about motion seems to be processed more slowly than information about colour, so that the former is delayed relative to the latter. (...) This, the paper argues, raises an important difficulty for retentionalism and its account of the temporal ontology of experiences: it suggests that a central background assumption about neural processing presupposed by retentionalism is false, at least in cases of visual asynchrony. The paper then explores the general significance of this result for retentionalism (§3). (shrink)

It is an apparent truism about visual perception that we can see only what is visible to us. It is also frequently accepted that visual perception is dynamic: our visual experiences are extended through, and can evolve over time. I argue that taking the dynamism of visual experience seriously renders certain simplistic interpretations of the first claim, that a subject at a given time can see only what is visible to her at that time, false: we can be meaningfully said (...) to see invisible objects. This counterintuitive result in turn focuses our attention on the relationship between perception and memory. I show that it is difficult to draw a clear or simple distinction between the two. Memory and perception rely on, and blend with, one another. Together, these claims point us away from understanding visual perception as a simple reflection of the environment, and instead as closer to a process of dynamic modelling that draws together occurrent stimulation and stored information.

Humans are complex systems, ‘macro-entities’, whose existence, behaviour and consciousness stem out of the configurations of physical entities on the micro-level of the physical world. But an explanation of what humans do and think cannot be found through ‘tracking us back’, so to speak, to micro-particles. So, in explaining human behaviour, including linguistic behaviour on which this paper focuses, emergentism opens up a powerful opportunity to explain what it is exactly that emerged on that level, bearing in mind the end (...) product in the form of the intra- and inter-cultural diversity. Currently there is a gap in emergentism research. On one hand, there are discussions in philosophy of the emergent human reality; on the other, there are discussions of social, cultural, or individual variation of these emergent aspects of humanity in the fields of anthropology, sociology, linguistics or psychology. What I do in this paper is look for a way to ‘trace’ some such diversified emergents from what is universal about their ‘coming to being’, all the way through to their diversification. My chosen emergent is human time, my domain of inquiry is natural-language discourse, and the drive behind this project is to understand the link between ‘real’ time of spacetime on the micro-level from which we emerged and the human time devised by us, paying close attention to the overwhelming diversity in which temporal reference is expressed in human languages. The main question is, where does this diversity fit in? Does understanding of this diversity, as well as of what lurks under the surface of this diversity, aid the emergentism story? My contribution to this volume on ‘the nature of structure and the structure of nature’ thus takes the following take on the title. The structure of human communication is at the same time uniform, universal, and relative to culture, in that it is emergent as a human characteristic, and as such compatible with the micro-level correlates in some essential ways, but also free to fly in different directions that are specific to societies and cultures. I explore here the grey area between the micro-level and the linguistic reflections of time—the middle ground that is emergent itself but that tends to be by-passed by those who approach the question of human flowing time from either end: metaphysics and the philosophy of time on the one hand, and contrastive linguistics, anthropological linguistics and language documentation on the other. I illustrate the debate with examples from tensed and tenseless languages from different language families, entertaining the possibility of a conceptual universal pertaining to time as degrees of epistemic modality. Needless to say, putting the question in this way also sets out my (not unassailable) methodology. (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.

ABSTRACTThe aim of the paper is to demonstrate the fruitfulness of the influential verb typology developed by Zeno Vendler for recent debates in the philosophy of perception. Section one explains t...

The way we represent and perceive time has crucial implications for studying temporality in conscious experience. Contrasting positions posit that temporal information is separately abstracted out like any other perceptual property through specialized mechanisms or that time is represented through the temporality of experiences themselves. To add to this debate, we investigate alterations in felt time in conditions where only conscious visual experience is altered through perceptual switches while a bistable figure remains physically unchanged. We predicted that if perceived time (...) is a function of temporally evolving conscious content, then a break in it (here via a perceptual switch) would also lead to a break in felt time. In three experiments, we showed participants a Necker cube that was manipulated to induce a perceptual switch (experiments 1(a) and 1(b)) or left to switch on its own (experiment 2). We asked participants to report both perceptual switches and felt durations (experiments 1(a) and 2) or only estimate time (experiment 1(b)). Over these three experiments, we find evidence of contraction of felt time in trials with a perceptual switch, consistent with the idea that perceived time is a function of temporally evolving conscious experience. Additionally, we present a phenomenological demonstration to support our empirical data. Overall, the study provides evidence for temporal mirroring and isomorphism in visual experience, arguing for a link between the timing of experience and time perception. (shrink)

As a typical subject, you experience a variety of paradigmatically temporal phenomena. Looking out of the window in the English summer, you can see leaves swaying in the breeze and hear the pitter-patter of raindrops steadily increasing against the window. In discussions of temporal experience, and through reflecting on examples such as those offered, two phenomenological claims are widely – though not unequivocally – accepted: firstly, you perceptually experience motion and change; secondly, while more than a momentary state of affairs (...) is presented in your ongoing perceptual experience, that which is presented nonetheless seems to be of a quite limited temporal extent. These two claims are frequently tied to the notion of the specious present. However, there has recently been a push back against the supposed link between perceived motion and the specious present. I argue that there are two ways of understanding this link, and while one has recently been the target of criticism, the other withstands such criticism. My overarching aim is to clarify the notion of the specious present through a discussion of the notion’s origins, in addition to recent criticism directed at the notion, with the hope of reframing how contemporary debates proceed.

The study of the contrast between fundamental aspects of spatial and temporal awareness offers a good opportunity to bring to light the relation between philosophical and scientific theories of consciousness. In this paper we critically examine important work by Rick Grush on spatial and temporal experience, and we show that while there is a valid claim for the relevant neuroscientific model to be one that supports Gareth Evans's stance on "behavioral space", there is not at present any scientific model that (...) offers comparable support for philosophical theories of temporal experience, despite some claims by Grush that might suggest the contrary. Moreover, we argue that careful attention to the spatial case allows us to locate the point at which even relatively successful cases of neuroscientific modeling and explanation are left wanting when their aim is to show that phenomenal features of experience are a function of the representational structures produced by our neural information-processing machinery: an aim widely shared by the predominant programmatic stance in current neuroscience research.
