Most accounts, including leading textbooks, credit Arthur Norman Prior with the invention of temporal (tense logic). However, (i) Jerzy Łoś delivered his version of temporal logic in 1947, several years before Prior; (ii) Henrk Hiż’s review of Łoś’s system in Journal of Symbolic Logic was published as early as 1951; (iii) there is evidence to the effect that, when constructing his tense calculi, Prior was aware of Łoś’s system. Therefore, although Prior is certainly a key figure in the (...) history tense logic, as well as modal logic in general, it should be accepted both in the literature that temporal logic was invented by Jerzy Łoś.

The present study aimed to investigate how native Japanese speakers learning Chinese choose preferred positions for temporal adverbs depending on their level of Chinese proficiency. A naturalness judgment task conducted on native Chinese speakers showed that the most natural position for Chinese temporal adverbs was before the subject and that placement after the locative prepositional phrase was incorrect. The same task applied to native Japanese speakers found the most natural position for Japanese temporal adverbs was (...) also before the subject. Further, when they appear at the beginning of a sentence, they provide the time for the entire sentence. Accordingly, temporal topicalization appears to influence naturalness decisions by both native Chinese and Japanese speakers. A point of difference was that in Japanese, a temporal adverb placed after a locative prepositional phrase was judged to be acceptable. When the same task was given to native Japanese speakers learning Chinese divided into three Chinese proficiency level groups, placement before the subject was the most preferred by the higher Chinese proficiency group. In addition, placement after the locative prepositional phrase was unfavored by them while the same position was frequently selected by the lower level group. As Chinese proficiency increases it appears that the preferred temporal adverb position is before the subject and the placement after the locative prepositional is judged to be unnatural. Thus, a sense of suitable temporal adverb positions in Chinese is influenced by the level of Chinese proficiency of native Japanese speakers. (shrink)

This volume constitutes the proceedings of the First International Conference on Temporal Logic (ICTL '94), held at Bonn, Germany in July 1994. Since its conception as a discipline thirty years ago, temporal logic is studied by many researchers of numerous backgrounds; presently it is in a stage of accelerated dynamic growth. This book, as the proceedings of the first international conference particularly dedicated to temporal logic, gives a thorough state-of-the-art report on all aspects of temporal logic (...) research relevant for computer science and AI. It contains 27 technical contributions carefully selected for presentation at ICTL '94 as well as three surveys and position papers. (shrink)

Common wisdom, philosophical analysis and psychological research share the view that memory is subjectively positioned toward the past: Specifically, memory enables one to become re-acquainted with the objects and events of his or her past. In this paper I call this assumption into question. As I hope to show, memory has been designed by natural selection not to relive the past, but rather to anticipate and plan for future contingencies -- a decidedly future-oriented mode of subjective temporality. This is not (...) to say memory makes no reference to the past. But, I argue, past-oriented subjectivity is a by-product of a system designed by natural selection to help us face and respond to the "now and the next". I discuss the implications of the proposed temporal realignment for research agendas as well as the potential limitations of measures designed to explore memory by focusing on its retentive capabilities.

Why does Plato write dialogues? Why more than one? The Temporality of Human Excellence begins with a brief introductory consideration of these questions, and concludes with a suggestion about two things: the intent of his use of this form, and the manner of its concrete realization in a set of two dozen or so dialogues. Taking up each dialogue as a separate drama, the reading seeks to focus attention on how each, by its characters, their interplay and conversation, and the (...) apparent lack of positive issue to the discussion they engage in, contributes to a sketch of human excellence as a complex power developed and grown into as consummation in the maturing, over time, of a human being.

Temporal binding is the phenomenon in which events related as cause and effect are perceived by humans to be closer in time than they actually are). Despite the fact that temporal binding experiments with humans have relied on verbal instructions, we argue that they are adaptable to nonhuman animals, and that a finding of temporal binding from such experiments would provide evidence of causal reasoning that cannot be reduced to associative learning. Our argument depends on describing and (...) theoretically motivating an intermediate level of representations between the lower levels of associations of sensory features and higher symbolic representations. This intermediate level of representations makes it possible to challenge arguments given by some comparative psychologists that animals lack higher-level abstract and explicit forms of causal reasoning because their cognitive capacities are limited to learning and reasoning at the basic level of perceptual associations. Our multi-level account connects time perception with causal reasoning and provides a philosophically defensible framework for experimental investigations that have not yet been pursued. We describe the structure of some possible experiments and consider the implications that would follow from a positive finding of temporal binding in nonhuman animals. Such a finding would provide evidence of explicit awareness of causal relationships and would warrant attribution of intermediate representations that are more abstract and sophisticated than the associations allowed by the lower level of the two-level account.

According to Leininger, presentists and growing blockers cannot explain why past and present regularities persist in the future. In order to do so, they would have to appeal to enforcers, such as causation, laws or dispositions. But in a world with no future, these enforcers are powerless and cannot guarantee future regularity. I disagree and argue that Leininger’s coordination problem can be met by distinguishing type- from token-level necessitation. Whereas token-level necessitation is cross-temporal and subject to Leininger’s coordination problem, (...) type-level necessitation is atemporal and immune to the coordination problem. For this solution to work, though, type-level necessitation must be ontologically prior to token-level necessitation. This forces us to adopt a Platonist position according to which universals are transcendent, and not immanent. (shrink)

Temporal discounting is a technical operation in climate change economics. When discount rates are positive, economic evaluation treats future benefits as less important than equivalent present benefits. This chapter explains and critically evaluates four different reasons economists have given for tying discount rates to the interest rates we observe in real-world markets. I suggest that while philosophers have correctly criticized three of these reasons, their criticisms of the fourth miss the mark. This is because philosophers have not taken heed (...) of the distinct analytical framework in which the fourth reason arises. (shrink)

In ordinary conscious experience, consciousness of time seems to be ubiquitous. For example, we seem to be directly aware of change, movement, and succession across brief temporal intervals. How is this possible? Many different models of temporal consciousness have been proposed. Some philosophers have argued that consciousness is confined to a momentary interval and that we are not in fact directly aware of change. Others have argued that although consciousness itself is momentary, we are nevertheless conscious of change. (...) Still others have argued that consciousness is itself extended in time. In this entry, the motivations and merits of these and other positions will be expounded and assessed. (shrink)

The temporal single-system (TSS) quantitative approach to Marx's economics is analysed. It is shown that TSS models lack a clear equilibrium concept and a coherent (dis)equilibrium methodology, and that Marx's propositions on value and exploitation are tautologically obtained (i) by constructing a money costs theory of value, where by assumption values are equal to market prices, apart possibly from short-run deviations; and (ii) by arbitrarily assuming that the undefined monetary expression of labour time is positive. In general, the shortcomings (...) of the analytical framework make TSS claims, including the proofs of the law of the tendential fall in the profit rate, unwarranted. (shrink)

Not only is freedom a shared concern of Sartre and Schelling, which would not be anything particularly unique, but for both philosophers, freedom must be articulated out of an ontological ground, or within the confines of an ontological system. A contradiction nevertheless appears to arise regarding the “orientation” of Sartre and Schelling’s respective “ontologies of freedom”: the freedom of Sartre, reflecting a contemporary stoic-inspired doctrine, is directed toward the future, while for Schelling, with affinities to the temporal logic of (...) psychoanalysis, freedom is oriented toward the past. This article presents both Sartre and Schelling’s ontological reasoning out of which either a progressively oriented freedom (the freedom to negate the present in the name of future “possibles”) or a retrogressively oriented freedom (the freedom to determine the ground of the present out of an indefinite, a-temporal becoming), before attempting to resolve this contradiction in the temporality of freedom by examining the position and role of the negative (of negation, contradiction, or nothingness), as either secondary or primary, within the ontology of each respective philosopher.

I spell out two theses, one shared by Kant and Heidegger, the other Kant’s alone: (1) there is a difference between “within-time-ness” (Innerzeitigkeit) and original or pure time (the temporal difference); (2) the temporal difference is articulated by a self-conscious act not bound by time. While each agrees that the “time-less” original or pure time has limits within which particular temporal determinations have their significance, Kant goes further in asserting that the pure ‘I’ must cognize the determinate (...) boundaries of original or pure time if objective cognition is to be possible. The ‘I’ thus rejects time as a horizon of its own significance. Understanding this argument suggests why Kant’s position is not as obviously susceptible to Heidegger’s criticism: not only does Kant positively argue that the ‘I’ is atemporal, but the content of this argument tells us why it is impossible for this understanding of the ‘I’ to result in a conception of it as ‘extant’ or a superadded representation in need of unification with temporality . Finally, it suggests that the dispute between Kant’s and Heidegger’s philosophical orientations rests not on the question of a lack of understanding of temporality, but on the question of how the ultimate conditions of intelligibility relate to their limits.

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. (shrink)

This article builds on feminist scholarship on new biologies and the body to describe the temporal politics of epigenetic research related to the human placenta. Drawing on interviews with scientists and observations at conferences and in laboratories, we argue that epigenetic research simultaneously positions placenta tissue as a way back into maternal and fetal bodies following birth, as a lens onto children’s future well-being, and as a bankable resource for ongoing research. Our findings reflect how developmental models of health (...) have helped recast the placenta as an agential organ that is uniquely responsive to environments during pregnancy and capable of embodying biological evidence about the effects of in utero experiences after birth. We develop the concept of ‘recursive embodiment’ to describe how placenta epigenetics is reimagining relationships between bodies and environments across developmental, epigenetic, and generational time, and the impacts this has for experiences of pregnancy and responsibilities related to children’s health.

This paper examines the intersecting of the themes of temporality and truth in Deleuze's philosophy. For the ancients, truth was something eternal: what was true was true in all times and in all places. Temporality (coming to be and passing away) was the realm of the mutable, not the eternal. In the seventeenth century, change began to be seen in a positive light (progress, evolution, and so on), but this change was seen to be possible only because of the immutable (...) laws of nature that govern change. It was not until philosophers such as Bergson, James, Whitehead – and then Deleuze – that time began to be taken seriously on its own account. On the one hand, in Deleuze, time, freed from its subordination to movement, now becomes autonomous: it is the pure form of change (continuous variation) that lies at the basis of Deleuze's metaphysics in Difference and Repetition (and is explored more thematically in The Time-Image). As a result, on the other hand, the false, freed from its subordination to the form of the true, assumes a power of its own (the power of the false), which in turn implies a new ‘analytic of the concept’ that Deleuze develops in What Is Philosophy?

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)

The paper develops an objection to the extensional model of time consciousness—the view that temporally extended events or processes, and their temporal properties, can be directly perceived as such. Importantly, following James, advocates of the extensional model typically insist that whole experiences of temporal relations between non-simultaneous events are distinct from mere successions of their temporal parts. This means, presumably, that there ought to be some feature(s) differentiating the former from the latter. I try to show why (...) the extensional models offers no credible ground for positing such a difference. (shrink)

This article proposes an interpretation of the status of the Grundnorm in Hans Kelsen’s legal theory which addresses the broader philosophical problem of the ultimate foundation of normativity. It begins by reviewing the main objections that have been raised against Kelsen’s theory, pointing out that most of these can be met by a ‘transcendental’ interpretation of the Grundnorm as a condition of possibility for legal cognition. It then argues that in order to solve the problem of the ultimate foundation for (...) legal validity it is also necessary to read the Grundnorm in light of the parallel category of ‘nomo-dynamicity’, which Kelsen introduced in all his legal writings beginning with the Pure Theory of Law of 1933. This yields a conception of legal validity as an ‘essentially temporal’ category, from the point of view of which the problem of ultimate foundations cannot emerge because the beginning is by definition not situated conceptually within time. The broader conclusion is therefore that overcoming the problem of the ultimate foundation of normativity requires abandoning the theologico-political assumption that valid norms are posited through a sovereign gesture analogous to that through which God is supposed to have created the universe ex nihilo. Construing normativity as ‘essentially temporal’ implies that the search for ultimate foundations must run into a category that is entirely foreign to political theology but well known to phenomenology: that of an ‘always-already’.

In this chapter, I discuss some ways in which debates about temporal experience intersect with wider debates about the nature of perception in general. In particular, I suggest that bearing in mind some general questions about the nature of perception can help with demarcating different theoretical approaches to temporal experience. Much of the current debate about temporal experience in philosophy is framed in terms of a debate between three specific main positions sometimes referred to as the extensional (...) model, the retentional model and the cinematic model. It is typically assumed that the differences between these three models are obvious. Yet, on closer inspection, it turns out to be surprisingly difficult to make out what exactly distinguishes the cinematic model from the extensional one, on the one hand, and from the retentional model, on the other. I criticise some existing ways in which the models are sometimes demarcated from one another, before suggesting that the differences between the three views become clearer if the debate between them is seen as turning on contrasting pictures of the nature of perceptual experience they embody.

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.

Analyses of errors from a sequential auditory recall experiment indicated that perceptual factors influence the shape of the serial position curve of recall errors. The signal to noise ratio and presentation rate of the stimuli, as well as presentation rate during a prior training session, affected item and order errors. For experiments in which Ss simply monitored the auditory sequences for a preassigned critical item, and in which items were recalled in addition to monitoring, analyses of montoring RTs provided (...) evidence that the requirement to recall induces perceptual difficulties.

_The Temporality of Political Obligation _offers a critique and reconceptualization of the ways in which our political obligations – what we owe to political authorities and communities, and the reasons why we ought to obey their rules – have been traditionally conceptualized, justified, and contested. Drawing from theories of time and temporality, Justin Mueller demonstrates some of the unacknowledged assumptions and theoretical blind spots shared among these ostensibly opposed positions, and the problems and contradictions that this neglect of time poses. (...) Enriching the literature on the philosophers Henri Bergson and Gilles Deleuze, Mueller demonstrates how their theoretical frameworks on time can be used to analyze a political problem that is usually confined to the concerns of normative liberal democratic theory. Politically, this book provides readers with the means to better identify and analyze the diverse temporalities they encounter in everyday life, and better understand their experiences of them. A welcomed and timely read which will be of interest to scholars involved in recent efforts to engage with the social and political dimensions and consequences of time and temporality. (shrink)

I argue that the semantic content of thoughts and the linguistic meaning of expressions are things with a history in the sense that they can be made fully intelligible only from the point of view of the future. I defend this position by articulating a version of a view known in the philosophy of language as temporal externalism. Temporal externalism about content is the view that the content of a subject’s thoughts and utterances at a time t (...) depends on features of the linguistic practices of her community after t. There are two different ways in which temporal externalism can be developed. First, one can take it to be the view according to which the meaning of an expression is given by the whole pattern of use, including future ones, of that expression. Alternatively, one can interpret temporal externalism as the view that the meaning of a speaker’s utterance is determined by the norms that govern or constrain her linguistic behaviour. These norms, which may be instituted at a later date, place their authoritative stamp upon prior conduct. I show that the first version of temporal externalism faces severe objections from which the second version is immune. I also provide a defence of this second position through an extensive discussion of some thought experiments. (shrink)

Temporal ontology is the philosophical debate on the existence of the past and the future. It features a three-way confrontation between supporters of presentism (the present exists, the past and the future do not), pastism (the past and the present exist, the future does not), and eternalism (the past, the present, and the future all exist). Most philosophers engaged in this debate believe that presentism is much more in agreement with common sense than the rival views; moreover, most of (...) them believe that being in agreement with common sense is epistemically valuable for a philosophical view. We studied experimentally non-experts’ ideas pertaining to the domain of temporal ontology, i.e., as we called it, common-sense temporal ontology, focusing on the Italian population. We found that a non-overwhelming majority of participants (~64%) favoured presentism, while two significant minorities favoured pastism (~19%) and eternalism (~17%). We think that our findings provide some support, albeit weaker than expected, for the view that presentism is more in agreement with common sense than the rival positions. (shrink)

In this paper we consider a claim that in the natural world there is no fact of the matter about the spatio-temporal separation of events. In order to make sense of such a notion and construct useful models of the world, it is proposed to use elements of a non-classical logic. Specifically, we focus here on causality, as a concept tightly related with the assumption of there being distinct, separate events, proposing a model according to which it can be (...) considered to be spatio-temporally graded. It is outlined how this can be described using the formalism of fuzzy sets theory, with the degree of causality varying between 1, that is no separation between causes and effects, and 0, that is perfect separation between causes and their effects as in classical ’billiard balls’ models of physical systems, namely such based on the notion of ideal mathematical point. Our model posits that subjective moments of time are like fuzzy sets, with their extension determined by local degrees of causality, resulting from information integration processes extended gradually in space and time. This, we argue, is how a notion of causality could be, to a certain degree, spared and reconciled with a variant of Bergsonian duration theory as formulated in the theory of continuous change. Relation of the proposed viewpoint to other theories, as well as possible solutions it suggests to various problems, in particular the measurement problem, are also discussed. (shrink)

Temporality is an under-researched area in entrepreneurship and business ethics, even though entrepreneurs are particularly affected by a fast-paced work environment. How do they position themselves in relation to the acceleration of time in order to construct meaning for their activity? We draw on fifty-four semi-structured interviews with entrepreneurs to outline the different ways in which they perceive a faster pace of work. We show how the meaning they give to their activity varies according to whether they accept or (...) resist the acceleration of time: (1) By claiming to accept a high work rate, entrepreneurs may see work as a way of keeping busy, having fun, forgetting, or achieving efficiency; (2) by asserting that they resist the acceleration of time, they view work as a way of setting ethical goals, doing their job better, experiencing unexpected encounters, or being creative. These two different perspectives on time and meaning are not incompatible: It is possible that achieving a harmonic balance between periods of acceleration and deceleration of time may foster the construction of meaningful entrepreneurship.

This paper is a comparative study based on the linguistic evidence in Vedic Sanskrit and Homeric Greek, aimed at reconstructing the space-time cognitive models used in the Proto-Indo-European language in a diachronic perspective. While it has been widely recognized that ancient Indo-European languages construed earlier events as in front of later ones, as predicted in the Time-Reference-Point mapping, it is less clear how in the same languages the passage took place from this ‘archaic’ Time-RP model or non-deictic sequence, in which (...) future events are behind or follow the past ones in a temporal sequence, to the more recent ‘post-archaic’ Ego-RP model that is found only from the classical period onwards, in which the future is located in front and the past in back of a deictic observer. Data from the Rigveda and the Homeric poems show that an Ego-RP mapping with an ego-perspective frame of reference could not have existed yet at an early Indo-European stage. In particular, spatial terms of front and behind turn out to be used with reference not only to temporal events, but also to east and west respectively, thus presupposing the existence of an absolute field-based FoR which the temporal sequence is metaphorically related to. Specifically, sequence is relative position on a path appears to be motivated by what has been called day orientation frame, in which the different positions of the sun during the day motivate the mapping of front onto ‘earlier’ and behind onto ‘later’, without involving ego’s ‘now’. These findings suggest that early Indo-European still had not made use of spatio-temporal deixis based on the tense-related ego-perspective FoR found in modern languages. (shrink)

The paper examines both the phenomenology of the manic self as well as critical aspects of manic neurobiology, focusing, with respect to both domains, on manic temporality. We argue that the distortions of lived time in mania exceed mere acceleration and are fundamental for manic affectivity. Mania involves radical acceleration and radical asynchronicity, which result in an instantaneous existence. People with mania rebel against the facticity of reality and suffer from an existential leap towards the future, in which the self (...) abandons normal temporal boundaries. Excerpts from the interviews with persons with mania who experienced psychosis illustrate this phenomenon. Commenting upon disrupted circadian rhythms in mania and the role of lithium in its treatment the paper posits manic temporality as the link through which manic phenomenology and manic neurobiology intertwine.

Extensionalism is, roughly, the view that perception occurs in episodes that are temporally extended (and thus capable of accomodating in their entirety phenomena taking a nonzero lapse of time to occur). This view is widely acknowledged to be incompatible with thin presentism, the second most popular position in temporal ontology. In this paper, I argue that extensionalism is also incompatible with several other positions in temporal ontology, namely those positing the existence of non-present times that host sentience—positions (...) I collectively refer to as the sentient non-present view. Most notably, extensionalism proves to be incompatible with B-theoretical eternalism, which is the most popular position in temporal ontology. (shrink)

The heart of my dissertation project is the proposal of a new updating rule for responding to learning experiences consisting of continuous streams of evidence. I suggest characterizing this kind of learning experience as a continuous stream of stipulated credal derivatives, and show that Continuous Probability Kinematics is the uniquely coherent response to such a stream which satisfies a continuous analogue of Rigidity – the core property of both Bayesian and Jeffrey conditionalization. In the first chapter, I define neighborhood norms (...) of rationality with reference to Kenny Easwaran’s definition of neighborhood properties. I summarize and comment on some of the key arguments in the dispute between time-slice epistemologists, who argue that there are no fundamentally diachronic norms of rationality, and the proponents of diachronic norms. I am sympathetic to two of the key motivations often given in support of the synchronist position: mentalist internalism and the idea that metaphysical disputes about the identity of persons in bizarre puzzle cases should not play a central role in epistemologists’ assessments of the rationality of agents. However, I argue that time-slice epistemology cannot adequately address the rationality of temporally-extended processes like reasoning and learning. Neighborhood norms present a viable third way between these two positions, capturing much of the spirit of the previously-discussed synchronist motivations while still providing just enough temporal structure to meaningfully guide and evaluate temporally-extended rational processes. Continuous Probability Kinematics is an example of one such neighborhood norm. In the second chapter, I develop my updating rule CPK and establish many of its core properties. Of special note here are the deep connections to Jeffrey’s Probability Kinematics, as well as some key differences. The net result of any CPK updating process will always be representable as a Jeffrey shift on the refined partition generated by the propositions that the agent is receiving direct evidence concerning. However, one crucial difference is that CPK provides an intuitive account of how to combine the effects of learning experiences that are each about fundamentally different underlying partitions. In CPK’s formalism, an agent can receive simultaneous evidence streams about an arbitrary (finite) number of propositions, which can themselves be evidentially related in any way. At any given instant, the result of the combination is a simple sum of the effects that learning about the individual propositions would have separately. CPK is concerned with a novel kind of learning experience and involves a novel characterization of evidence. The third and final chapter of this dissertation is concerned with explaining what this characterization of evidence means and with arguing that it can be the basis for genuine learning. I begin by characterizing learning experiences in terms of the Value of Information, and prove a Value of Information theorem for CPK learning experiences under the assumption of a Martingale constraint on the agent’s prior distribution over the signals that they might receive. I examine Timothy Williamson’s arguments that evidence must be propositional and express my skepticism. I then explore two different routes to model agents who update by CPK as if they are learning some propositional content and updating the rest of their credences by Bayesian conditionalization on this content. The second of these two routes provides a very interesting lens to reexamine the evidential commitments that underwrite updating by CPK, which I analyze. (shrink)

This paper describes Stein’s process for establishing the relationship between finite and temporal beings and infinite and eternal beings. Although she contextualized her research in the fields of phenomenology and ontology, Stein surpasses these domains. Following Aquinas, Stein uses the analogy to trace the ascension towards the sense of Being. However, this process ends up being closest to the position of St. Augustine. In fact, the author first draws up a temporal analogy and then a personal analogy (...) starting from two pieces of evidence: the certainty of “I am”, from Augustine, Descartes, and Husserl, and the divine “I am”, according to the name that God reveals of himself: “I am who I am”. Through personal analogy, the author goes beyond phenomenology and ontology, while the category “person” includes both being and an attributed fullness. (shrink)

This article discusses recent work in metaphysics on temporal parts. After a short introduction introducing the notion of a temporal part, we examine several well‐known arguments for the view that ordinary material objects such as tables, trees, and persons have temporal parts: (1) positing temporal parts makes it possible to solve puzzles of coincidence (e.g., the statue/lump puzzle); (2) positing temporal parts makes it possible to solve the problem of intrinsic change over time; and (3) (...) the existence of temporal parts can be demonstrated based on considerations about vagueness in composition. We conclude by examining briefly a recent argument that the dispute over whether there are temporal parts is merely verbal. (shrink)

Research on temporal comparison has shown that people dissociate themselves from their past to attain a positive self view. Social comparison research has demonstrated that the distinctness of contextually activated information determines whether a recalled self exerts assimilation or contrast effects on the current self. However, hardly any study addressed individual differences. Also, very little is known about whether the ease or difficulty to date past events and experiences influences current self-judgments. We present a new scale capturing the degree (...) of the current self time extension. Three studies support the notion that temporal self-extension determines how past selves are accessed and processed, regarding both the abstractness with which self-knowledge is retrieved and the experienced temporal distance to the past. These findings have important implications for temporal as well as social comparison processes. (shrink)

Previous studies consistently showed age-related differences in temporal judgment and temporal memory. Importantly, emotional valence plays a crucial role in older adults’ information processing. In this study, we examined the effects of emotions at the intersection between time and memory, analysing age-related differences in a temporal source memory task. Twenty-five younger adults (age range 18–35), 25 old adults (age range 65–74), and 25 old–old adults (age range 75–84) saw a series of emotional pictures in three sessions separated (...) by a one-day rest period. In the fourth session, participants were asked to indicate in which session (1, 2, or 3) they saw each picture. Results showed that old–old adults tended to collocate negative pictures distant in time, while positive stimuli were remembered as more recent than real, compared to neutral pictures. To a lower extent, people over 65 showed the same pattern of results. In contrast, emotional valence did not affect younger adults’ temporal positioning of stimuli. Current findings fit well with the Socio-Emotional Selectivity Theory’s assumptions and extended the literature on the positivity effect to temporal source memory. (shrink)

How can a persisting object change whilst remaining the same object? Lewis, who frames this as the problem of temporary intrinsics, presents us with the perdurance solution: objects persist by having temporal parts which may have differing properties. And in doing so he characterises the opposing view as persisting but not by having temporal parts – a view he calls endurance. But this dichotomous picture of Lewis, although now widely embraced, misses out the orthodox historic view – a (...) view I call temporal holism: objects persist by having temporal parts to which they are ontologically prior. (In the perduring solution, by contrast, the temporal parts are ontologically prior.) This paper sets out this temporal holist solution and makes clear its differences from perdurantist and endurantist solutions. Although temporal holism has a long and illustrious history, this history has not been explicitly recognised. I begin the task of recognising this history in this paper, in order to make clear the nature of temporal holism, and to show that it is a long-established, well supported and distinctive position. The paper sets out, too, how temporal holism solves other ontological problems so that, despite its current neglect, temporary holism has the potential to greatly enrich contemporary philosophical debates.

Here I argue that the hyper-individualistic and rationalistic ethical paradigms – originating in the late eighteenth century and dominating moral philosophy, in various permutations, ever since – cannot capture the moral concerns evoked by the prospect of global climate change. Those paradigms are undone by the temporal and spatial scales of climate change. To press my argument, I deploy two famous philosophical tropes – John Rawls's notion of the original position and Derek Parfit's paradox – and another that (...) promises to become famous: Dale Jamieson's six little ditties about Jack and Jill. I then go on to argue that the spatial and especially the temporal scales of global climate change demand a shift in moral philosophy from a hyper-individualistic ontology to a thoroughly holistic ontology. It also demands a shift from a reason-based to a sentiment-based moral psychology. Holism in environmental ethics is usually coupled with non-anthropocentrism in theories constructed to provide moral considerability for transorganismic entities – such as species, biotic communities, and ecosystems. The spatial and temporal scales of climate, however, render non-anthropocentric environmental ethics otiose, as I more fully explain. Thus the environmental ethic here proposed to meet the moral challenge of global climate change is holistic but anthropocentric. I start with Jamieson's six little ditties about Jack and Jill.

In lieu of an abstract, here is a brief excerpt of the content:Anonymous Temporality and Gender:Rereading Merleau-PontyMegan M. BurkeThis Essay Provides a Feminist reading of Merleau-Ponty’s notion of anonymity in order to show that it is a critical resource for a feminist account of gender. For Merleau-Ponty, anonymity is a structure of temporality that is prior to the cogito; it is a time that actualizes the reflective self. It gestures away from ontological commitments rooted in presence and calls attention to (...) how senses inform and actualize one’s reflective experience, which illuminates how it is that certain habits become sedimented or deeply rooted into the structure of one’s lived experience. As such, anonymity provides a useful framework for understanding how and in what ways gender normativity is taken up and resisted in experience. Yet feminist readings of Merleau-Ponty and anonymity are divided. On the one hand, there is a strong criticism of his work in general and anonymity in particular and, on the other hand, there is an effort to recuperate aspects of his project, including anonymity. Four examples can help frame this disparate feminist reception of his work:1. Merleau-Ponty neglects sexual difference. For example, Elizabeth Grosz suggests, “Merleau-Ponty leaves out—indeed, is unable to address—the questions of sexual difference, the question of what kind of human body he is discussing, what kind of perceptual functions, and what kind of sexual desire result from the sexual morphology and particularity of the subject” (Grosz 1994, 10). [End Page 138]2. Anonymity neglects sexual difference. Shannon Sullivan is representative of this point, claiming, “Merleau-Ponty’s notion of the anonymous or impersonal body … leads one to overlook” difference; “Merleau-Ponty fails to realize” difference; “He is wrong” (Sullivan 2001, 71).3. Anonymity illuminates sexual difference. For Silvia Stoller “[W]ith the help of Merleau-Ponty … sexual difference presupposes an anonymous sexuality which underlies gender identifications,” making anonymity important to a phenomenological account of sexual difference (Stoller 2013).4. Merleau-Ponty’s account of embodied subjectivity provides insight into the lived experience of femininity. Feminist analyses of female body comportment, such as those of Iris Marion Young and Sandra Bartky, suggest that gender is a process of sedimentation (Young 1990; Bartky 1990). More specifically, they suggest gender becomes a lived experience through the repetition of particular behaviors and actions such that they become a deeply habituated part of one’s being in the world.While the feminist criticisms of Merleau-Ponty are important insofar as they caution against the acceptance of universal claims about existence, they also overlook anonymity’s relationship to time. Given that Merleau-Ponty’s characterization of anonymity is temporal through and through, this oversight is problematic. Without an account of anonymity as a kind of temporality, we miss the value of anonymity and the further insight that can be drawn from it in relation to gender. In what follows, then, I propose a solution to the disparate reception of his work. I suggest that reading anonymity as a structure of temporality illuminates how gender is taken up in lived experience. And, I suggest that anonymity can provide a strong account of gender normativity when one understands the parallels between sedimentation and anonymity with respect to temporality. By showing the strong connection between sedimentation and anonymous temporality, I suggest that it is ontologically and politically helpful to understand gender as a lived time.In the first section of this paper, I will address the main criticisms of anonymity provided by Shannon Sullivan and Luce Irigaray, while also paying attention to those from Elizabeth Grosz, Judith Butler, and Beata Stawarska. For Sullivan, Grosz, and Butler, Merleau-Ponty’s anonymous body is a neutral body, a body that fails to account for gender differences. Irigaray and Stawarska suggest that anonymity is the mark of patriarchy, making ethical and ontological solipsism fundamental to Merleau-Ponty’s work. In each of these cases, anonymity provides nothing useful for and is, in fact, a detriment to feminist projects.In the second section of this paper, I turn to Stoller’s positive reading of anonymity. For Stoller, anonymity is a political and ethical resource that challenges gender norms because it can allow for transformation in... (shrink)

© 2015 Wong,Tassone,Rivera and Simon.Carriers of the fragile X premutation allele have an expanded CGG trinucleotide repeat size within the FMR1 gene and are at increased risk of developing fragile x-associated tremor/ataxia syndrome. Previous research has shown that male fXPCs with FXTAS exhibit cognitive decline, predominantly in executive functions such as inhibitory control and working memory. Recent evidence suggests fXPCs may also exhibit impairments in processing temporal information. The attentional blink task is often used to examine the dynamics of (...) attentional selection, but disagreements exist as to whether the AB is due to excessive or insufficient attentional control. In this study, we used a variant of the AB task and neuropsychological testing to explore the dynamics of attentional selection, relate AB performance to attentional control, and determine whether fXPCs exhibited temporal and/or attentional control impairments. Participants were adult male fXPCs, aged 18–48 years and asymptomatic for FXTAS and age-matched male controls. We found that fXPCs did not differ from controls in the AB task, indicating that the temporal dynamics of attentional selection were intact. However, they were impaired in the letter-number sequencing task, a test of executive working memory. In the combined fXPC and control group, letter-number sequencing performance correlated positively with AB magnitude. This finding supports models that posit the AB is due to excess attentional control. In our two-pronged analysis approach, in control participants we replicated a previously observed effect and demonstrated that it persists under more stringent theoretical constraints, and we enhance our understanding of fXPCs by demonstrating that at least some aspects of temporal processing may be spared.

Philosophers have often posited a foundational calling voice, such that hearing its call constitutes subjects as responsive and responsible negotiators of normative claims. I give the name ldquo;transcendental conscience to that which speaks in this founding, constitutive voice. The role of transcendental conscience is not – or not merely – to normatively bind the subject, but to constitute the possibility of the subject's being bound by any particular, contentful normative claims in the first place. I explore the ontological and (...) class='Hi'>temporal status of transcendental conscience, using Heidegger's account of conscience in Being and Time as my textual touchstone. I ask what performative structure the call of conscience might have that would enable it to constitute normative responsiveness, and I raise some temporal conundrums surrounding this structure. I argue that it is incoherent to attempt to give a literal, chronological account of the origin of normative grip and response. I suggest that we can best understand the founding calls of conscience, not as literal events occurring in regular time, but as events that can only show up retrospectively, as occurring in an ever-receding, unlocalizable past, and that these calls can only be figured mythically and metaphorically. Appropriating a Derridean term, I claim that the voice of transcendental conscience must be that of a lsquo;ghost, whose call binds us by haunting us – a haunting that is no less transcendentally necessary for its inability to be translated into a literal historical event.

Fundamental problems in developmental biology, such as the generation of asymmetry, differential transcription, and the execution of positional information, are all exhibited by a prokaryotic system, the Caulobacter cell cycle. Progeny cells resulting from each cell division have different developmental programs with respect to patterns of transcription and the initiation of DNA replication. The binary fission that yields dissimilar progeny results from asymmetry generated in the parent cell. An aspect of this fundamental developmental event is the temporally‐controlled biogenesis of a (...) polar flagellum. Several flagellar promoters require the histone‐like protein, integration host factor (IHF) for transcription activation. IHF introduces bends in DNA resulting in the reorganization of the higher‐order structure of the promoter region. These promoters appear to be transcribed from the chromosome in the swarmer pole of the predivisional cell. The newly replicated chromosomes in the predivisional cell differ in sedimentation coefficient and in the ability to initiate replication in the progeny cell. We hypothesize that the differential higher order structure of the two chromosomes contributes to both replication potential and transcription specificity. (shrink)

The traditional debate over theories of reference of natural kind terms faces a serious dilemma. On the one hand, although direct reference theory, or the causal–historical analysis of reference to natural kinds, is still highly influential in the philosophy of language, there is a notorious “qua” problem: direct reference theory cannot uniquely determine the referents of natural kind terms. On the other hand, the standard descriptivism does not accommodate our externalist intuition. We propose temporal externalist descriptivism, where relevant future (...) theorists determine references by past speakers. This position makes the externalist intuition about reference compatible with descriptivism about natural kind terms by ensuring the possibility of mistakes in the past and present practice. It also provides a defense of the controversial claim of temporal externalism based on a descriptivist analysis of reference. While causal–historical analysis focuses on inheritance through history, a reference has both a past and a future. In this sense, reference to natural kinds is essentially a provisional phenomenon.

Positive Psychology Interventions as an Opportunity in Arab Countries to Promoting Well-being AbstractIn this perspective paper, we emphasize the importance of further research on culturally-sensitive positive psychology interventions in the Arab region. We argue that these interventions are needed in the region because they not only reduce mental health problems but also promote well-being and flourishing. To achieve this, we shed light on the cultural elements of the Arab region and how the concept of well-being differs from that of Western (...) culture. We review the research conducted in Arabia, briefly evaluate the quality of this research and list some adapted measurements. We furthermore propose guidelines and recommendations for future evidence-based positive psychology interventions research to align with the national culture in various sectors and community samples that contribute to the development of well-being in the Arab world.Introduction Extensive research on Positive Psychology Interventions (PPIs) - defined as activities focus on promoting positive feelings, thoughts, or behaviour (Sin & Lyubomirsky, 2009) - has shown their effectiveness in well-being and mental illness (e.g., Chakhssi et al., 2018; Hendriks et al., 2020). A recent review of 347 studies showed that PPIs have a significant effect on promoting quality of life and well-being and reducing anxiety and depression (Carr et al., 2020). However, the issue is that most of these studies (82%) remain narrow in focus only on Western Educated Industrialised Rich Democratic (WEIRD) countries (Hendriks et al., 2019). Therefore, they may not be effective for other countries such as the Arab countries where there are various cultural differences. This highlights the key role that culture can play in enhancing PPIs engagement, acceptability, and eventually, effectiveness (Hendriks & Graafsma, 2019). Recently, the field of PP in the Arab region has begun to grow (Basurrah et al., 2021; Rao et al., 2015). However, studies conducted in these countries are scant and of poor methodological quality. We have found humble quantity and quality of empirical studies. Yet, Arab countries, home to 5% of the world’s population, have a burden of mental health problems above global levels (GBD 2015 Eastern Mediterranean Region Mental Health Collaborators, 2018). Prevalent stigma, war and conflict were some of the contributors (Maalouf et al., 2019). Thus, to properly address this cultural stigma against mental health problems, PPIs could provide an additional role alongside traditional psychology approaches (e.g., Cognitive Behavioural therapy - CBT). Further, in light of the political conditions that some Arab countries are going through and the negative effects that they cause, it has become necessary to use the method of prevention that is the focus of PP and not only of treatment as a strategy for applications and practice. It has been noted that the mental health care system in the Arab region focuses highly on illnesses treatment and neglects the significant role that PP plays in enhancing human potential and well-being. We - here in Arabia –are becoming more influenced by many global issues particularly the COVID-19 pandemic and their impact on mental health and well-being (e. g. prevalence of stress, anxiety, depression among the general population during the pandemic (Salari et al., 2020). In response, Waters et al. (2021) have recently presented how positive psychological factors can play a significant role in buffering mental illness, enhancing mental health throughout the pandemic, and building positive processes and capacities that can help to promote future mental health.Here in this perspective paper, we highlight the cultural aspects of Arab countries. Specifically, we present previous PPIs research conducted in Arabia and briefly evaluate the quality of this research. Importantly, we discuss the need of developing an indigenous and culturally sensitive PP among the Arab region (Lambert et al., 2015).Arab Culture “Arab World,” which comprises 5% of the world’s population, refers to the Arab countries in the Middle East and North Africa. Despite the increasing pace and progress of different businesses in many Arab countries, individual communities are still limited in certain prominent economic places. Arab people rather gather in collective communities. They generally share the same Arabic Islamic culture, speak the same language, and descend from the same Arab families when going back in history no matter what nationality they have nowadays. Yet, very many changes came to communities before borders were drawn between countries and after. For instance, geography, topography, demography, and socio-economic status affect peoples’ nature of jobs and lifestyles. For example, Arabs in the east, west, or the middle have similar tongues; however, almost every Arab country has its accent. Therefore, people need to go back to the formal Arabic language ‘Fus-ha’ or learn more about different Arabic dialects when communicating cross-countries. According to Hofstede’s model (2011) based on the individualism-collectivism dimension, the Arab countries (Eastern society) have been classified as a collectivist culture, where their identity and decisions are influenced by social systems. In contrast, the United States (Western society) has been classified as an individualist culture focusing on individual decisions. Although there are degrees of individualism among Arabs in certain countries, they still share collective common characteristics. Here, we explore the meaning of collectivistic conceptions of the self, emotions, values, and religion in Arab countries and how they differ from those in individual Western cultures. The Self Since the field of PP focuses on the development of self, it is vital to recognize that self-concept varies across cultures. Individualism generally emphasises the self-directed and autonomous individual (Realo et al., 2002). People in individualist countries focus primarily on their personal characteristics (e.g., motives, abilities) to build their self-concept. On the other hand, collectivism refers to several social structures that highly value the groups to which people belong, such as family and tribe (Realo, 2003). People in collectivist countries such as the Arab countries focus primarily on their relationships with others to build their self-concept (Markus & Kitayama, 1991). Hence, research from Arab countries should focus on the core elements of collectivism when implementing PPIs to make a significant, meaningful impact. For example, people from a collective culture may experience a greater enhancement in well-being when practising interventions that are more prosocial and group-oriented such as compassion, performing acts of kindness, writing a gratitude letter, and using character strengths in everyday context including social context, compared with self-oriented interventions such as identifying character strengths. Emotions, value, and Religion Research shows that Western culture emphasises the goal of maximizing positive emotions, while Eastern culture emphasises embracing and balancing positive and negative emotions (Leu et al., 2011). To illustrate, culture plays an important role in influencing perceptions of happiness. People in individualist countries value happiness highly. In contrast, people from the collective countries value low arousal positive emotions (Leu et al., 2011) and exhibit a fear of happiness (Joshanloo & Weijers, 2014; Joshanloo, 2013). Hence, the influence of positive emotions plays a limited role in the mental health of Eastern society. Speaking of Value, for an Arab, the family is the centre of honour and the most important social unit. This loyalty has an impact on every part of an Arab’s life. Arabs honour their families and highly value their friendships. Therefore, future research could shed more light on group-oriented interventions (e.g., kindness) that focus more on the relationship with family, friends, and community. When it comes to religion, Arab society has a rich culture in values and believes that place a high emphasis on spirituality. Religion is the most important and distinctive aspect of Arab culture. Arab countries vary in terms of religion, with Islam being the predominant religion in most of them. Well-being (Hedonic and Eudaimonic) It is necessary here to clarify what is meant by hedonic and eudaimonic definitions of well-being. While the term ‘Hedonic’ is based on the pursuit of maximum levels of pleasure (feeling good), the term ‘Eudaimonic’, on the other hand, is based on meaning and the development of virtues (functioning well; Keyes & Annas, 2009). Research indicates that cultures are not equally supportive of hedonic and eudaimonic aspects (Joshanloo & Jarden, 2016). In comparison to collectivism, hedonism appears to be more congruent with individualism (Joshanloo, 2014). Pleasure and positive emotions are considered a way to pursue happiness in Western culture, while this method is not highly favoured in Eastern cultures (Lee et al., 2013); Because they consider suffering and negative emotions as contributing factors to spiritual development. Therefore, the eastern perspective is more in line with a eudaimonistic view which emphasises virtues, meaning, and feeling of belongingness. However, although we believe that both approaches can be found to a certain level in both cultures, the differences suggest that there are different routes to happiness. Positive Psychology in the Arab region Positive psychology - "the scientific study of what makes life most worth living" (Seligman & Csikszentmihalyi, 2000) - is one of the newest branches of psychology. It focuses on three main pillars: (1) positive subjective experiences (such as happiness and love); (2) positive individual characters (such as gratitude and compassion); and (3) positive institutions (for the application of positive principles within institutions and organizations; Seligman & Csikszentmiha lyi, 2000). Some of the main topics of interest in positive psychology include character strengths, gratitude, hope, happiness, mindfulness, optimism, positive thinking, and resilience. Within the applications of this science, various domains of well-being (such as happiness, engagement, positive emotions, and meaning) can be enhanced by practising positive psychology interventions (Sin & Lyubomirsky, 2009). Interestingly, these interventions have also produced benefits beyond well-being, such as reduced mental health issues (Chakhssi et al., 2018; Hendriks et al., 2020).Nowadays, PP is increasingly noticed in the Arab world (Lambert & Pasha-Zaidi, 2019; Rao et al., 2015). In recent years, there has been a great effort to explore the PP field across Arab countries. Several initiatives have emerged aimed at promoting well-being and flourishing. For example, the Middle East Journal of Positive Psychology published its first volume in 2015. On the International Day of Happiness in 2017, United Arab Emirates University launched its Emirates Center for Happiness Research. Meanwhile, Effat University in Saudi Arabia started the first Positive Psychology and Well-being Research Lab, the first symposium, and the first PP course. In 2019, Louise Lambert and Nausheen Pasha-Zaidi published the first regional text entitled “Positive Psychology in the Middle East/North Africa.” There are other efforts spent in the region as well; such as the work conducted in Egypt. Ibrahim Younus established the Arab Association for Positive Psychology https://www.psycholearn.com/en/associative.php which provides several courses on PP and also published a book entitled “The Power of Positive Psychology” (Younus, 2017). Despite this development, nothing can compare to the quantity and even quality of research in other countries. In light of our observations, the few PP studies may be attributed to the lack of awareness of the constructive approach and prevention compared to problem-solving. An Arab dentist once said: “people do not come to me until they are badly in pain.” In any case, many studies have taken place in Arab countries in the last decade, more of which are descriptive and less of which experimental. For example, Abdel-Khalek (2010) found positive correlations between quality of life, subjective well-being, and religiosity among students in Kuwait. Abdel-Khalek (2016) developed “the Arabic Scale of Religiosity,” which significantly correlated with PP variables among students in Algeria, Kuwait, and Egypt. Recently, empirical studies on PPIs have arisen in Arab-Islamic countries. More attention has been focused on promoting well-being and alleviating the high burden of mental health problems in the region (GBD 2015 Eastern Mediterranean Region Mental Health Collaborators, 2018). For instance, several studies examined the effectiveness of mindfulness among university students (e.g., Al-Ghalib & Slim, 2018; Awad, 2019; Thomas et al., 2016), parents of children with autism (Rayan & Ahmed, 2016) and addicted adults (Al-Rashidi, 2018). Such an intervention has positive effects. Participants who practised mindfulness reported reduction in stress and depression as well as improvement in well-being and resilience. Moreover, the results of a recent pilot study found positive impacts on enhancing emotional regulations and reducing stress among Arab teachers (Berkovich-Ohana et al., 2020). Some studies have also begun to examine various interventions targeting character strengths (Basurrah et al., 2020; Chérif et al., 2020), self-compassion (Elaiwah, 2017), positive thinking (Mohammed et al., 2014; Hadad, 2014), and hope (Zaki, 2016). Interestingly, a new finding considering the fear of happiness among people from collective countries has been examined. Lambert et al. (2019) provided evidence that a 14-week PPIs programme has an impact on reducing the fear and fragility of happiness beliefs among university students in the United Arab Emirates.Since Arab countries place great emphasis on spirituality, several authors have considered the aspect of religion when implementing PPIs. For instance, an empirical study by Al-Seheel and Noor (2016) found that expressing gratitude towards God “Allah” increases the happiness of the Muslim more than the usual gratitude intervention. Additionally, Al-Ghalib and Salim (2018) examined a religiously sensitive mindfulness-training programme with university students and found a positive effect on life satisfaction and a slight reduction in stress, depression, and anxiety. Hence, the role of religion is vital to make the interventions more relevant to Arab culture where people can connect Islamic philosophy with PP theories and practices. These studies reviewed here provide further support for the need for culturally sensitive interventions among the Arab population. More recently, the first systematic review of PPIs in Arab countries was conducted by Basurrah et al. (2021; the protocol has been published in BMJ Open and the final manuscript has been submitted for publication). Reviewing a total of 39 studies, the most commonly studied interventions were mindfulness, positive thinking, and resilience. Only a handful of studies examined gratitude, character strengths, forgiveness, self-compassion, savouring, or finding flow. Further analysis revealed that most studies from Arab countries have several methodological limitations. This included a lack of protocol guidelines, few well-designed randomized controlled trials (RCTs), blinding issues, small sample sizes, lack of active control groups, and lack of research into certain populations (e.g., teachers, employees, and people in distress in refugee camps). Discussion PP was founded on an individualistic framework (Christopher & Hickinbottom, 2008). To ensure that PPIs are culturally meaningful, this paper includes some cultural elements of the Arab region that should be considered to serve the needs of the Arab population. In the Arab world, some people may believe that PP is solely about happiness and being positive. If so, it is important to educate the public about the findings of rigorous studies evaluating PPIs such as gratitude, hope or flow on health, well-being and performance. To explain the value and effectiveness of these evidence-based approaches, examples might include studies linking gratitude with benefits for people with heart disease (Cousin et al., 2021), or how PPIs can promote quality of life in cancer patients (Casellas-Grau et al., 2014). There is some evidence about PPIs being effective in improving well-being in the Arab region, but research in this region is still in its infancy and little information is available regarding PPIs and the experience of Arabs participating in such interventions. Hence, there is still much more to investigate in this regard. Future research should empirically examine the effectiveness of various unstudied interventions such as savouring, gratitude, self-compassion, character strengths or finding flow. A combination of quantitative and qualitative approaches is required to provide an in-depth understanding of Arabs’ experience and impressions of PPIs and how and why they work. This may provide useful information to inform the appropriate design of PPIs to suit Arab culture and needs. Furthermore, while some research on PPIs has been carried out in the region, most of these studies have been of poor quality that suffered from small sample sizes, confounding factors, and a high degree of bias. To overcome these issues, future research should improve research quality, including protocol guidelines and well-designed RCTs. In particular, research should include randomization, allocation, blinding, power analysis to determine adequate sample size, active control groups to reduce bias, and follow-up periods of at least 12 months.Among the most popular resources that future PP practitioners may refer to are the International Positive Psychology Association (IPPA) and the International Positive Education Network (IPEN). Also, we recommend the Middle East Journal of Positive Psychology and the first regional book (Lambert & Pasha-Zaidi, 2019). To develop and/or adapt a multi-component PPIs, we would recommend referring to Character Strengths (Peterson & Seligman, 2004), the theory of well-being (PERMA Model: Positive Emotion, Engagement, Relationships, Meaning, and Accomplishment; Seligman, 2011), and the Five Ways to Well-being: Connect, Be Active, Take Notice, Keep Learning, and Give (Aked et al., 2008). Finally, single-component PPIs are based on theories like Broaden-And-Build (Fredrickson, 2004), Hope (Snyder et al., 2002), and Self-Determination (Deci & Ryan, 2012) can be also considered. Two other concepts that would be usefully applied are ‘Savouring’ (Bryant & Veroff, 2007) and Phillip Zimbardo’s Time Perspective (Stolarski et al., 2015). For instance, savouring has a positive temporal orientation to reminiscing the good memories from the past, enjoying the hedonic present moments, and willing proactively to make a better future. Now, what is even maybe more interesting for Muslims is “Transcendent Future” where all intentions, words and actions are devoted to that life after death. In addition, there is a model already prepared for the clinical purpose called Positive Psychotherapy (PPT). Tayyab Rashid and Martin Seligman published a PPT manual for clinicians in 2018. And for cross-cultural applications, including Muslim Arab culture, Rashid and Al-Haj Baddar (2019) have written a paper presenting PPT and its efficacy. PPT overview in detail shows sessions, themes, skills, practice, and cultural considerations where a mixture of PPIs based on PERMA, Strengths, and other PP concepts can be found. Regarding PP measurements, it is highly recommended to generate indigenous tools based on cultural backgrounds reviewed here in the article. An example of this is a tool for measuring Muslim well-being by including domains beyond what is found in Western literature. So far, in the Arab region, several attempts have been made to adapt PP tools. For example, Marei Salama-Younes (2018) validated the Arabic versions of different measures of well-being (e.g., satisfaction with life scale, the subjective vitality scale). Other validated scales as well include the self-compassion scale (Alabdulaziz et al., 2020), and the passion scale (Salama-Younes & Hashim, 2018). Conclusion This paper has discussed the cultural aspects of Arab countries and the need of developing culturally sensitive PPIs. The past decade has seen an increase in mental health problems in the Arab region. Stigma and lack of awareness have been always there. Among the issues are also wars, conflicts, and displacement in many Arab countries such as Iraq, Lebanon, and Palestine (Hassan et al., 2016). These indicate an urgent need to prevent mental illness and promote well-being. Indeed, we highlighted the importance of integrating culture with PPIs, following the guidelines for the cultural adaptation of PPIs (Hendriks & Graafsma, 2019) and the ethical guidelines for PP practice (Jarden et al., 2020). Another significant contribution of this paper is to highlight the importance of improving the quality of research conducted in Arab countries. In brief, this paper has several practical implications. It is an open invitation for researchers, policymakers, and practitioners alike to be more exposed to PP; as well as to better conceptualising and adapting interventions and measurement tools to the local culture in different sectors to maximize their effectiveness. And as we consider it as an invitation for us too, here we are starting a PPIs practice guide in Arabic language and for Arab practitioners. The insights gained from this paper may be useful for placing well-being on top of priorities for achieving individual, organizational, and optimal national functioning in different sectors. There is also a need to change the stigma or negative beliefs about seeking health for psychological support, which is an issue for countries in the Middle East (Baess, 2018). (shrink)

How does art – literature, visual art, or music – endure over time? What special power does it possess that enables it to “transcend” time – to overcome temporal distance and speak to us not just as evidence of times gone by, but as a living presence? The Renaissance, which discovered this transcendent power of art in the classical sculpture and literature it admired so strongly, concluded that great art is impervious to time – “timeless”, “immortal”, “eternal” – a (...) belief that left a profound impression on Renaissance culture and often found expression in its poetry. Subsequently the same belief exerted a powerful influence on Enlightenment aesthetics and, in various forms, it still lingers on today. The nineteenth century, however, saw a major challenge to this thinking. Hegel, Marx and Taine stressed the historical embeddedness of art and for these three thinkers, as for a series of more recent theorists such as Sartre, Benjamin, and Adorno, art belongs within the world of historical change. To locate its essential qualities in a “timeless” realm removed from the flow of history would be an idealist illusion. The conflict between these two positions has resulted in an impasse, and today we appear to lack any viable account of one of art’s key features – its capacity to transcend time. André Malraux proposes an entirely new account of this unique power of art. For Malraux, as this article explains, art is neither exempt from history (timeless) nor wholly inseparable from it. Art overcomes temporal distance – transcends time – through metamorphosis, a process of continual transformation in significance in which history plays an essential, but not exclusive, part. “La métamorphose,” Malraux writes, “est la vie même de l’œuvre d’art dans le temps, l’un de ses caractères spécifiques.” This proposition, to which contemporary aesthetics has so far paid very little attention, is a revolutionary step in our thinking about art. -/- .

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)

R.L. Epstein and E. Buitrago-Díaz aspire to present a vitally new approach to temporal logic, an approach based on the idea of absolute truth-values. They claim the existing approaches are confused and incoherent, and contain a significant number of nonsenses. The alleged problems are generated by truth-values being relativized to positions in time. The fundamental incoherence consists in some confusion between propositions and their schemata. Epstein and Buitrago-Díaz have formulas be simply true or false and describe fixed areas of (...) time. I endeavour to show that all objections Epstein and Buitrago-Díaz raise to existing temporal logic are misunderstandings. The calculus they present is easily reconstructable in existing calculi, so there is no new approach here. However, the calculus is correct and may be of some interest in logic. (shrink)

Theories of the representation of specific kinetic and spatiotem-poral features of movement range from the explicit assertion that temporal aspects of movement are not represented (Kugler et al. 1980) to the idea that they are represented and that they have neurophysiological correlates (Ivry & Corcos 1993; Ivry & Keele 1989). Jeannerod's thesis is that mental and visual images have common mechanisms and that there is a link between the image to move and the mechanisms involved with movement. The target (...) article takes the position that certain parameters are coded in motor representations (sect. 4) but that the duration of an action is not one of them. This position is based on the work of Gottlieb et al. (1989b) and of Decety et al. (1989). Both these studies are worth considering in detail. In Note 1, Jeannerod suggests that: “in time-constrained tasks subjects control the amplitude parameter of force impulses, whereas in spatially constrained tasks the duration of the force impulse is affected by accuracy demands.” This is not exactly correct. Excitation pulse intensity (amplitude) is modulated both in tasks that require spatial and those that require temporal accuracy. Excitation pulse duration is modulated for changes in movement distance and inertial load. If subjects are required to be very accurate spatially, they will move at less than maximum speed for a given distance and this is achieved by lower levels of excitation intensity (Gottlieb et al. 1990).
