Philosophers and intellectual historians generally recognize pragmatism as a philosophy of progress. For many commentators, pragmatism is tied to a notion of progress through its embrace of meliorism – a forward-looking philosophy that places hope in the future as a site of possibility and improvement. I complicate the progressive image of hope generally attributed to pragmatism by outlining an alternative account of meliorism in the work of William James. By focusing on the affectivity and temporality of James’s meliorism, I argue (...) that James offers a non-progressivist version of hope that is affectively tempered by melancholy and oriented temporally toward the present.

We investigate agents that have incomplete information and make decisions based on their beliefs expressed as situation calculus bounded action theories. Such theories have an infinite object domain, but the number of objects that belong to fluents at each time point is bounded by a given constant. Recently, it has been shown that verifying temporal properties over such theories is decidable. We take a first-person view and use the theory to capture what the agent believes about the domain of (...) interest and the actions affecting it. In this paper, we study verification of temporal properties over online executions. These are executions resulting from agents performing only actions that are feasible according to their beliefs. To do so, we first examine progression, which captures belief state update resulting from actions in the situation calculus. We show that, for bounded action theories, progression, and hence belief states, can always be represented as a bounded first-order logic theory. Then, based on this result, we prove decidability of temporal verification over online executions for bounded action theories. (shrink)

In the first section of the chapter, I scrutinize Howard Stein’s 1991 definition of a transitive becoming relation that is Lorentz invariant. I argue first that Stein’s analysis gives few clues regarding the required characteristics of the relation complementary to his becoming—i.e. the relation of indefiniteness. It turns out that this relation cannot satisfy the condition of transitivity, and this fact can force us to reconsider the transitivity requirement as applied to the relation of becoming. I argue that the relation (...) of becoming need not be transitive, as long as it satisfies the weaker condition of “cumulativity”: for a given observer the area of the events that have become real should not diminish as time progresses. I show that there are actually two relations of becoming that meet this weakened condition: Stein’s (transitive) relation of causal past connectibility and the (non-transitive) relation that is the logical complement of the future causal connectibility. In the second part of the chapter I defend Stein’s notion of temporal becoming against the attack that appeals to quantum-mechanical non-locality. I critically evaluate the argument given by Mauro Dorato (1996) that purports to show that space-like separated measurements done on the EPR system have to be mutually determinate. Finally, in order to account for the truth of counterfactual statements that link the space-like separated outcomes, I propose a dynamic conception of becoming, according to which the sphere of determinate events as of a given point may depend on the physical phenomena transpiring at this point.

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?

This paper elaborates the problem of temporal unity for dynamic presentism and diagnoses the source of that problem in the dynamic presentist’s discarding the traditional C-series in its avoidance of McTaggart’s (1908, 1927) A-series paradox. This C-series provided the fixed structure of time which the transitory aspects of time then followed, and thereby unify those transitory aspects. It then considers ersatzer presentism as an ostensible solution to the problem of temporal unity by providing a new abstract C-series (namely (...) an ersatz-B-series) for dynamic presentism. However, after a closer examination of the details of this proposal, it is found that the ersatz-B-series itself needs to be temporally variable to capture the transitory aspects of time that it is meant to track. Consequently, it cannot provide the fixed structure of time required to unify the transitory aspects of time into a temporal series. It is therefore suggested that dynamic presentists look for a more course-grained determiner of temporal progression to construct the presentist-friendly C-series required to unify their transitory aspects of time.

This paper proceeds from the premise that time and temporality constitute a distinct philosophical problem for Marx and Engels’s materialist concept of history in The German Ideology. It is thus necessary to “temporalize” this concept of history: to situate it in relation to the active production of a dynamic difference between the past, the present, and the future. After revisiting the philosophical dimensions of Marx’s concepts of materialism, the human, and need, this article uncovers a temporality within the materialist concept (...) of history that is irreducible to a historicist framework of linear, progressive time.

In lieu of an abstract, here is a brief excerpt of the content:Philosophy, Psychiatry, & Psychology 12.3 (2005) 195-198 [Access article in PDF] Implicit and Explicit Temporality Thomas Fuchs Keywords implicit/explicit temporality, embodiment, intersubjectivity, desynchronization, melancholia, schizophrenia Since Minkowski (1970), Strauss (1966), v. Gebsattel (1954), and Tellenbach (1980), temporality has been a main subject of phenomenological psychiatry. Drawing on philosophical concepts of Bergson, Husserl, and Heidegger, these authors have analyzed psychopathologic deviations of time experience, mainly from an individual point of (...) view, for example, as a slowing down or inhibition of lived time in depression or obsessive–compulsive disorder. Their analyses are still most valuable today, but may be carried further by introducing concepts such as embodied and intersubjective temporality into psychopathology. Martin Wyllie (2005), by opening up a wide scope of temporal phenomena and related concepts, makes a laudable effort to contribute to such a progress.In my commentary, I would like to propose a distinction that is suggested by much of Wyllie's analysis and may shed further light on psychopathology, namely between implicit and explicit temporality. If we look at a child while obliviously playing with his toys, lost to the world, we may assume that there is no sense of the time passing. Lived time runs with the movement of life, implicit in the child's experience of being engaged in his play and directed toward his goals. It "unfolds through the processes of bodily activity" (Wyllie 2005). Future and past do not stand out against the pure presence of "becoming." This implicit mode of temporality is retrieved every time that we are absorbed in what we are doing, and may even reach the climax of "flow experiences" (Csikszentmihalyi 1988) where the sense of time is lost in unimpeded, fluent performance.However, this changes when a gap arises between need and satisfaction, desire and fulfillment, or plan and execution. Now the future appears as a "not yet" or "yet to come," experienced as the temporality of awaiting, striving, or longing for. Time is felt as passing by and refusing the desired fulfillment; it becomes conscious or explicit. A similar gap arises between the present and something irretrievably lost, bringing the past to consciousness as a "no more." Again time is experienced explicitly, but now as moving on relentlessly and separating us from the lost object. The gap to the past may not be bridged any more: this is the temporality of missing or mourning. In both cases, explicit time arises as a negation of implicit or lived time (here my use of the term is a bit divergent from Wyllie's); it is experienced as a "not yet" or "no more," often with a component of displeasure or suffering (Fuchs 2001a, 2003)."Implicit" versus "explicit time" thus come near to another distinction well known in phenomenology, namely between the "lived" and [End Page 195] the "corporal body" (Leib versus Koerper). The first term refers to the body functioning in the tacit mode, as the medium of everyday performance. The second term points to the body as turning into the object of attention, for example, when it puts up resistance to our purposes, or is used as an instrument deliberately (Fuchs 2001b). In fact, implicit temporality and tacit performance of the body are nearly synonymous: Lived time may be regarded as a function of the lived body, opened up by its potentiality and capability. The more we are engaged in our tasks, the more we forget time as well as the body; we are, as it were, "inside time." On the other hand, in explicit temporality the body often appears in the corporal or explicit mode as well. For example, when falling ill, we experience our body no more as a tacit medium but rather as an object or obstacle, while we notice the slowing down of time and may even feel excluded from the movement of life. Thus, embodiment and temporality have a parallel background–foreground structure.I now try to carry these considerations further by including the intersubjective dimension of time. In an earlier paper, I describe the attunement of the living being to its environment as a continuous synchronization on the biological as... (shrink)

As this century has found new temporalities to replace linearity, discontinuities have become commonplace. Discontinuity, if carried to a pervasive extreme, destroys linearity…There were two enormous factors, beyond the general cultural climate, that promoted composers' active pursuit of discontinuities. These influences did not cause so much as feed the dissatisfaction with linearity that many artists felt. But the impact has been profound. One factor contributing to the increase of discontinuity was the gradual absorption of music from totally different cultures, which (...) had evolved over the centuries with virtually no contact with Western ideas…Cross-cultural exchange in music will, of course, never destroy aesthetic boundaries, but music of non-Western cultures continues to show Western composers new ways to use and experience time. The second tremendous influence on twentieth-century musical discontinuity was technological rather than sociological: the invention of recording techniques. Recording has not only brought distant and ancient musics into the here and now, it has also made the home and the car environment just as viable for music listening as the concert hall. The removal of music from the ritualized behavior that surrounds concertgoing struck a blow to the internal ordering of the listening experience. Furthermore, radios, records, and, more recently, tapes allow the listener to enter and exit a composition at will. An overriding progression from beginning to end may or may not be in the music, but the listener is not captive to that completeness. We all spin the dial, and we are more immune to having missed part of the music than composers might like to think. Jonathan D. Kramer is an associate professor of music theory and composition and director of electronic music at the College-Conservatory of Music of the University of Cincinnati. The present essay is part of his book, Time and Meaning in Music. (shrink)

The current study examined whether pigeons could learn to use abstract concepts as the basis for conditionally switching behavior as a function of time. Using a mid-session reversal task, experienced pigeons were trained to switch from matching-to-sample (MTS) to non-matching-to-sample (NMTS) conditional discriminations within a session. One group had prior training with MTS, while the other had prior training with NMTS. Over training, stimulus set size was progressively doubled from 3 to 6 to 12 stimuli to promote abstract concept development. (...) Prior experience had an effect on the initial learning at each of the set sizes but by the end of training there were no group differences, as both groups showed similar within-session linear matching functions. After acquiring the 12-item set, abstract-concept learning was tested by placing novel stimuli at the beginning and end of a test session. Prior matching and non-matching experience affected transfer behavior. The matching experienced group transferred to novel stimuli in both the matching and non-matching portion of the sessions using a matching rule. The non-matching experienced group transferred to novel stimuli in both portions of the session using a non-matching rule. The representations used as the basis for mid-session reversal of the conditional discrimination behaviors and subsequent transfer behavior appears to have different temporal sources. The implications for the flexibility and organization of complex behaviors are considered. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Temporal Registers in the Realist NovelIlya BernsteinIThere are two ways of thinking about time: in terms of sequences of events, and in terms of time-scales. In the first case, each event is conceived of as having a "before" and an "after": it is categorized as part of a sequence and distinguished from other events by its position in that sequence. In the second case, there is no "before" (...) and "after": events are conceived of as occupying different time-scales and distinguished from one another by being associated with durations of greater or lesser magnitude.1 Thus, the same situation may be categorized alternatively as an unfolding succession of events (event 1, event 2, event 3...) or as a progression of overlapping events on expanding time-scales (the second-event, the minute-event, the hour-event...). In what follows, I will argue that this distinction can shed light on narrative structure—as well as musical form—and that it has particularly interesting implications for literary realism.It may be claimed that this distinction between two ways of approaching time has been an explicit theme in the arts over the course of their history. Different musical forms, for instance, may be seen as being oriented toward one paradigm or the other. Thus, melody aesthetically suggests a sequential conception of time. Melodic forms are supposed to take listeners on a journey from point A to point B, by way of a succession of points in between. By contrast, a form such as the fugue addresses itself to discovering different degrees of density and intensity within the [End Page 173] same event, as it were. It adds layer upon layer, aesthetically dilating the event without moving away from it. The ideology of melody, we might say, thus leans toward a conception of time as a sequence, while the ideology of the fugue suggests a scaling notion of time.Echoes of the distinction between these two aesthetic alternatives may also be found in literature, as embodied in different approaches to narrative. Narrative, conceived of as a succession of episodes, suggests a sequential conception of time, oriented around a "before" and an "after." Yet within these parameters, a spectrum of tendencies may be identified. In some literary forms, the succession of episodes is organized to suggest the idea of a passage from one event to the next (Shakespearean drama, the realist novel), as the notions of "before" and "after" are projected onto ideas of past and future. In others, the succession of episodes represents the layer-by-layer assembly of some larger imaginative or conceptual construct (as is true, in different ways, of such texts as Plato's dialogues, the Divine Comedy, and any number of religious, philosophical, or allegorical narratives): "before" and "after" are interpreted not so much in terms of a past and a future, as in terms of premises and conclusions.Within this spectrum, the novel—and perhaps the realist novel in particular—would appear to be the literary form par excellence that embodies a sequential conception of time. It thematizes and dramatizes time's passage—the unknowability of the future and the irretrievability of the past—more exhaustively than any other narrative genre. Yet as I hope to show below, while the explicit themes of literary realism treat fictional events as a sequence (event 1, event 2, event 3...), its implicit organization is grounded in time-scales and directs readers' attention to differentiations among events taking place at different temporal registers (the sentence-event, the chapter-event, the novel-event...).III would like to begin exploring the theoretical distinction laid out above by going back to music and focusing on an empirical observation that has been made about a variety of musical forms. It has been pointed out that when people listen to a piece of music, they retain in their memory, at greater or lesser degrees of awareness, a certain segment of what they have just heard; this memory serves as a background for their perception of incoming sounds and as a frame of reference for their experience of them. Consequently, musical forms may be characterized, [End Page 174] compared, and distinguished from one another based... (shrink)

Flight delay is one of the most challenging threats to operation of air transportation network system. Complex network was introduced into research studies on flight delays due to its low complexity, high flexibility in model building, and accurate explanation about real world. We surveyed recent progress about flight delay which makes extensive use of complex network theory in this paper. We scanned analyses on static network and temporal evolution, together with identification about topologically important nodes/edges. And, we made a (...) clarification about relations among robustness, vulnerability, and resilience in air transportation networks. Then, we investigated studies on causal relations, propagation modellings, and best spreaders identifications in flight delay. Ultimately, future improvements are summarized in fourfold. Under Complex Network, flight operation relevant subsystems or sublayers are discarded by the majority of available network models. Hierarchical modelling approaches may be able to improve this and provide more capable network models for flight delay. Traffic information is the key to narrow the gap between topology and functionality in current situations. Flight schedule and flight plan could be employed to detect flight delay causalities and model flight delay propagations more accurately. Real flight data may be utilized to validate and revise the detection and prediction models. It is of great importance to explore how to predict flight delay propagations and identify best spreaders at a low cost of calculation complexity. This may be achieved by analyzing flight delay in frequency domain instead of time domain. Summation of most critical nodes/edges may not be the most crucial group to network resilience or flight delay propagations. Effective algorithm for most influential sequence is to be developed.

This article recapitulates and develops the attempts in the Nietzschean traditions to address and overcome the proliferation of nihilism that Nietzsche predicted to unfold in the next 200 years (WP 2). Nietzsche approached nihilism not merely as a psychology but as a labyrinthic and pervasive historical process whereby the highest values of culture and founding assumptions of philosophical thought prevented the further flourishing of life. Therefore, he thought nihilism had to be encountered and experienced on many, often opposing, fronts to (...) be fully consumed and left behind. Thus, just as Nietzsche captured the subtle reinventions of nihilism in new forms in his time, in the new doers assumed behind new deeds (WP 488), this article focuses on the contemporary tectonic shifts brought by digital technology and challenges subjectivation and narrativization of algorithmic will to power in human-like interfaces such as ChatGPT. Having identified philosophers and himself as the most advanced nihilists in their overvaluation of truth, in the 4th part of Thus Spoke Zarathustra, Nietzsche grappled with the difficult, perhaps impossible, temporality of post-nihilistic historicity that oscillates between highest creativity and highest truths, especially in the sections entitled The Shadow and At Noon whereby he explored new temporal techniques to evade the relapses into temporal nihilisms of the notions of linear progress or eternity (TSZ, 4). By drawing on this juncture, this article offers ways to address transfigurations of nihilism behind new technological performances of subjectivity. The article points toward creative temporalities beyond narrativity and subjectivity insofar as the statistical operations and probabilistic estimations of language-models exceed grammatical construction of meaning. This multifaceted application of his thought on the contemporary ontic reality is necessary to perceive our comet's incalculable movement as a veritable ray of sunshine. (shrink)

Beginning with the influential discussion of the dialectic of progress found in Amy Allen’s The End of Progress, this paper outlines some difficulties encountered by critical theories of normative justification drawing on the early Frankfurt School. Characterizing Adorno and Horkheimer’s critical social theory as a dialectical reflection eschewing questions of normative foundations, I relate their well-known treatment of the dialectic of enlightenment reason and myth to their critique of capitalist society as a negative totality. By exploring the concepts of historical (...) development used by Adorno and Horkheimer to describe both the progressive domination of capitalism, and the formation and cultivation of reflective consciousness, I trace the importance of progression and its inseparable relationship to regression in these early versions of critical theory. The dialectical social theory found here recognizes the persistence of social contradictions on both a methodological level and on the level of theory’s development and expression, a connection potentially obscured by a division of historical progress according to its temporal orientation. Particularly in Adorno’s later work, an opposition to the negative social totality requires notions of cultivation and learning which work against the prevailing forms of conceptual thinking, including the concern for the stability of rational foundations.

The turn to optimism makes figures of progress, consumption, self-making and empowerment appear in various genres of chick-lit. These narratives, however, are often still shaped by a depressive tone that is distinct from one that says that women have more options than happy-ever-after, even while heterosexual romance remains a structuring force. This article takes the Ghanaian web-series An African City as its example to explore this ambivalence. An African City offered its first season in 2014 and was immediately received as (...) ‘Africa’s own Sex and the City’, praised for challenging the image of a backward Africa, while criticised for offering an unrealistic account of life for urban African women. The series is set around the lives of five women, one of whom plays the leading role as narrator. The ‘African city’ serves as another character, rather than a mere backdrop for the action to unfold. I argue that the various characters perform an ongoing ambivalence towards progress, always stuck in a look backward. It is not simply that the quest for romance fails as part of the drama, but that the drama of failure itself folds onto both the African city and African women as figures that remain eternally stuck in their relation to the temporalities that accrue around modernity.

Platonic paideia is a mainstream concept in traditional philosophy and humanistic circles generally. It is closely connected with social progress brought about by the dynamics of enlightenment and self-fulfillment, symbolized by the allegory of the cave. The main contention of this paper is that the philosophical grammar of this simile is more precarious than is often recognized. Plato’s apparently intuitive narrative blends together two features that do not easily mix, namely explicit, categorical dualisms, and temporal processes of development. The (...) second feature is superimposed upon the first, more elementary, one, suggesting that a philosopher-teacher can be in charge of mankind’s ascent towards illustrious goals.

It is from this bleak view of ordinary, ‘commonsense’ life that the narrative’s drive is derived. How might... (shrink)

Naive mereology studies ordinary conceptions of part and whole. Parts, unlike portions, have objective boundaries and many things, such as dances and sermons have temporal parts. In order to deal with Mark Heller's claim that temporal parts "are ontologically no more or less basic than the wholes that they compose," we retell the story of Laplace's Genius, here named "Swifty." Although Swifty processes lots of information very quickly, his conceptual repertoire need not extend beyond fundamental physics. So we (...) attempt to follow Swifty's progress in the acquisition of ordinary concepts such as 'table'. (Puzzles of precision and intrusion appear along the way.) Swifty has to understand what tables are before understanding what temporal portions of tables are. This is one reason for regarding tables as ontologically prior to table portions. intrusion appear along the way.). (shrink)

Condorcet's classical Enlightenment statement of human progress became an essential element of nineteenth- and twentieth-century consciousness, but by the millennium grand narratives had fallen victim to a disillusioned cultural climate. Now Steven Pinker, like Condorcet drawing on a wide range of contemporary “knowledges,” has reasserted a sweeping narrative of human progress in The Better Angels of Our Nature: Why Violence Has Declined. Mapping a spectacular long-term decline in person-on-person violence and reduction in deaths due to war, Pinker celebrates the spread (...) of a cultural pattern of self-restraint, sensitivity to human suffering, and recent regard for human rights, due to the modern state and gentle commerce capitalism.For Pinker the human condition has gotten steadily better, the decline of violence is an accomplishment we can savor and an impetus to cherish the forces of civilization and enlightenment that made it possible. Why then are so many so negative about modernity? Citing the psychology of temporal proximity to horrific events and the bad-news predilection of the media, Pinker ignores the specifically modern and less directly brutal institutionalized forms of violence as well as the profound ambivalence of progress. He decisively demonstrates the drop in certain kinds of violence, but his account becomes strangely ideological, recapitulating key Cold-War themes—the individual against totalitarianism, the Enlightenment against the counter-Enlightenment, rationalism and freedom against murderous utopianism—distorting his study in the name of gentle commerce, Marxism, and anti-Communism.

The relationship between time and voice about unethical behaviour has been highlighted as a key area for exploration within the voice and silence field (Morrison Annual Review of Organizational Psychology and Organizational Behavior 10:79–107, 2023). Previous studies have made only modest progress in this area, so we present a temporal lens which can act as a guide for others wishing to better understand the role of time and voice. Applying the concept of theory adaptation (Jaakkola AMS Review 10:18–26, 2020), (...) a method which attempts to build on a given field through the application of a new theoretical lens, we begin by reviewing what is known in relation to voice about unethical behaviour specifically. Then we introduce two temporal frameworks, one suggested by Ancona, Okhuysen, and Perlow (Ancona et al. The Academy of Management Review 26:645–663, 2001a; Ancona et al. The Academy of Management Review 26:512–529, 2001b) as a useful way of analysing time in organisations, and a second one by Bansal, Anna, and Wood, (Bansal et al. Academy of Management Review 43:217–241, 2018) focusing on the way organisations include voice into their temporal rhythm. We then draw conclusions about the role of time in relation to voice about unethical behaviour and identify three insights; a) it takes time for voices to generate evidence for unethical behaviour, b) perceptions of unethical behaviour change over time, and c) it is most difficult to voice about unethical behaviour at the time it is most needed. Our recommendations for future avenues of research based on these insights recommend new research designs better suited to explore the relationship between voice and time and a focus on how the formality of voice mechanisms shapes the timing of voice.

This study investigated the second language processing and acquisition of Chinese temporality, specifically the interaction of grammatical and lexical aspects. An experimental group of 31 English-speaking learners of Chinese and a control group of 29 native speakers of Mandarin Chinese completed an online sentence-picture matching task and an offline translation task. Results from these experiments demonstrated the prototype effect: In aspectual development, perfective aspect started with telic verbs and progressive aspect started with activity verbs, in accordance with the Aspect Hypothesis, (...) both for online processing and offline comprehension. The prototype effect of the grammatical aspect was evident for activity verbs but less so for accomplishment verbs in the L2 group across tasks, and this was explained through language-specific properties and L2 learners’ instructional input. In addition, L2 proficiency and working memory capacity were found to modulate these processes. (shrink)

Based on an empirical illustration of Onta pottery and more broadly a discussion of the Japanese Mingei movement, we study the intimacy between craft work, ethics and time. We conceptualize craft work through the temporal structure of tradition, to which we find three aspects: generational rhythms of making; cycles of use and re-use amongst consumers and a commitment to historically and naturally attuned communities. We argue these temporal structures of tradition in craftwork are animated by two contrasting but (...) co-existing ideas of the good: the moral and the ethical. By developing the work of Elizabeth Grosz, we conceptualize this distinction between moral and ethical as a temporal phenomenon, specifically in differing relations to ideas of the future. Moral aspects of craft work understand the future as a progression from past, whether in preserving practices and norms, or improving upon them in relation to ideals. Ethical aspects understand the future as inherently open to chance and divergence, valuing difference, accident and the possibilities for creativity these entail. Empirically, we show evidence of both aspects in the case of Mingei—a organized movement dedicated to preserving and promoting traditional Japanese craft work. We contribute to studies of craft work by revealing and classifying its temporal aspects. We contribute to studies in business ethics by conceptualising a generative distinction between morals and ethics configured through differing understandings of time. (shrink)

Although the chinese have a heightened sense of time, The concepts of time and temporality developed in their culture are remarkably different from those developed in the west. Certain time-Concepts familiar to the westerners are completely lacking in the chinese tradition.

Here I discuss the basic elements, major stages, and completion of progressive evolution. The cosmic world of self-realization is based on extensive self-development within a closed contour: temporal counter-transitions of spatial counter-elements (energy bonds and media and, basically, substance structures) form of local worlds within it through evolution of informational structures. The organic world of reproduction develops through the open informational path: the initial substance, through energy exchange and metabolism, reproduces similar substance; the latter interacts with the environment and, (...) subsequently, reproduces its like, and so on. The animal world of self-regulation builds up a closed informational contour in the environment through the informational input and command output. The human world of self-cognition forms the intensive type of development within the internal closed informational contour of cognition. Counter-transitions of ideal images and signs relate to their real prototypes. In the course of cognition, abstractive thinking develops and brings man to the possibility of reflection of the initial world in its integrity (thus, elevates man to the infinite, by Hegel).

The concept of agency is of crucial importance in cognitive science and artificial intelligence, and it is often used as an intuitive and rather uncontroversial term, in contrast to more abstract and theoretically heavy-weighted terms like “intentionality”, “rationality” or “mind”. However, most of the available definitions of agency are either too loose or unspecific to allow for a progressive scientific program. They implicitly and unproblematically assume the features that characterize agents, thus obscuring the full potential and challenge of modeling agency. (...) We identify three conditions that a system must meet in order to be considered as a genuine agent: a) a system must define its own individuality, b) it must be the active source of activity in its environment (interactionalasymmetry) and c) it must regulate this activity in relation to certain norms (normativity). We find that even minimal forms of proto-celular systems can already provide a paradigmatic example of genuine agency. By abstracting away some specific details of minimal models of living agency we define the kind of organization that is capable to meet the required conditions for agency (which is not restricted to living organisms). On this basis, we define agency as an autonomous organization that adaptively regulates its coupling with its environment and contributes to sustaining itself as a consequence. We find that spatiality and temporality are the two fundamental domains in which agency spans at different scales. We conclude by giving an outlook to the road that lies ahead in the pursuit to understand, model and synthesis agents. (shrink)

There are two contrasting views on the decision-making for life-sustaining treatment in advanced stages of dementia when the patient is deemed incompetent. One is to respect the patient's precedent autonomy by adhering to advance directives or using the substituted judgement standard. The other is to use the best-interests standard, particularly if the current judgement on what is best for the incapacitated patient contradicts the instructions from the patient's precedent autonomy. In this paper, I argue that the protracted clinical course of (...) dementia over many years requires the extended perspective of a progressive decision-making process—extended in both social space and time. The ongoing debate between these two competing views has missed this perspective by focussing on an exclusive disjunction between the competent former self and the incompetent current self. Drawing on theories of situated cognition in cognitive science, I will show that the cognition of a demented patient can be viewed as extended and embodied by her supportive social environment. As the disease progresses, the content of the mind of a demented person becomes partially constituted by such external resources along with her diminishing intrinsic mind. With this understanding, medical decision-making for a demented patient can be construed as a temporally and socially extended practice. A collective decision-making body consisting of the patient, her family and surrogates, and the clinician, should make progressive decisions as a whole over years of the disease course. Finally, I will provide a practical example of how this proposal can be applied in clinical practice. (shrink)

This article analyses the teleological argument justifying historical progress in Kant's Guarantee of Perpetual Peace. It starts by examining the controversies produced by Kant's claim that the teleology of nature supports the idea of a providential development of humanity towards moral progress and the possibility of achieving a cosmopolitan political constitution. It further illustrates how Kant's teleological argument in Perpetual Peace needs to be assessed with reference to two systematically relevant issues: first, the problem of coordination linked to the necessity (...) of realizing the ‘highest good’ as a historical end of practical reason, and secondly the problem of continuity posed by the temporal limitation of all individual efforts to cultivate moral dispositions. To illustrate the implications of both issues for the teleological argument in Perpetual Peace, the article draws attention to some important developments in Kant's analysis of teleology following the Critique of Judgment.

In previous works, we presented a modification of the usual possible world semantics by introducing an independent temporal structure in each world and using accessibility functions to represent the relation among them. Different properties ofthe accessibility functions have been considered and axiomatic systems which define these properties have been given. Only a few ofthese systems have been proved tobe complete. The aim ofthis paper is to make a progress in the study ofcompleteness for functional systems. For this end, we (...) use indexes as names for temporal flows and give new proofs of completeness. Specifically, we focus our attention on the system which defines injectivity, because the system which defines this property without using indexes was proved to be incomplete in previous works. The only system considered which remains incomplete is the one which defines surjectivity, even ifwe consider a sequence ofnatural extensions ofthe previous one. (shrink)

We highlight recent progress in neuroimaging and neuropsychological research on memory mechanisms in the medial temporal lobe that speaks to the involuntary nature of memory retrieval processes. We suggest that evidence form these studies supports Barzykowski and Moulin's proposal that memory signals involved in experiences of familiarity and déjà vu can be generated in the absence of retrieval intentionality.

This article focuses on the affective potential of anticipation, in its ready endorsement of the unknown, as a formative lens for theorising feminist temporalities. I draw from earlier readings of Luce Irigaray’s conceptual paradigm of sexual difference to examine how its articulation of a feminist future that is inherently unknowable might contribute to recent debates on the temporalities of feminist thought. The article presents two broadly intersecting lines of argument. I first emphasise the continued centrality of sexual difference in its (...) anticipatory imperative for thinking feminism but – or perhaps, especially – through a contradictory retrieval of the term that re-narrates its contemporary significance. In other words, it is precisely the retroactive position that sexual difference occupies that exacts a critical reorientation of existing modes of feminist temporalities; it moreover does so as a theoretical construct that altogether circumvents our understanding of feminism as a progress narrative. Secondly, I build upon Drucilla Cornell’s contentions in Beyond Accommodation that the unknown futurity inaugurated by the trajectories of sexual difference demands a dimension of inquiry that is inevitably aesthetic (1991). I identify a possibility of literature’s reinvigoration in emergence narratives of feminist theorising, particularly in a certain ethical capacity precipitated by its affective experience of enchantment, which mirrors the ‘wonder’ that sexual difference incites. If we are to continue to use literature as a conducive space of feminist analysis, then it is the forward-looking perpetuation of feminist narratives that must also be rethought for their investment in the multiple contingencies of anticipation.

Rapid urbanization has meant that cities around the world must deal with problems like traffic congestion, aging infrastructure, affordable housing, and climate change. Increasingly, policymakers are turning to investments in technology and digital infrastructure to address these problems. Yet the move towards so-called smart cities is not simply responsive, and policymakers increasingly advocate for smart city initiatives as a necessary step towards objective, efficient, and rational governance. This understanding of technological interventions as inherently progressive, however, causes many to overlook the (...) erasures, biases, and limitations that emerge from trying to leave the past behind. As the problems associated with this enthusiasm become more apparent, the smart city movement must therefore recalibrate its relationship to not just technology but time itself. Building on deconstructive temporalities emerging out of quantum physics, I argue that cities must begin drawing from alternative temporalities more open to the intersections between past, present, and future. As such, I suggest that the time has come to replace the ideal of the smart city with that of the spectral city – an incomplete city haunted by the ghosts of the past. (shrink)

The Stiftung Ökologischer Landbau (SÖL), founded in the mid-1970s, set out to promote organic farming in the Federal Republic of Germany (FRG). To this end, it brought together protagonists from the scientific community and the environmental movement to build a knowledge base for organic agriculture by drawing on the science-based concepts of natural and organic farming of the 1920s and 1930s. Based on the history of its founding, its structure, and work, this article demonstrates that temporality played an essential role (...) in the establishment of alternative bodies of knowledge. Contrary to the established model of linear scientific-technological progress, the aim was to return to bodies of knowledge and practices that had largely disappeared from the scientific canon of knowledge, but also from agricultural practice, in previous processes of forgetting and marginalization. This is exemplified by the so-called “spade diagnosis,” a method developed in the 1930s by soil biologists to assess arable soil. Concepts and practice of counter-knowledge amounted to a model of conservative modernization in organic farming. (shrink)

Susan Faludi's Backlash, first published in 1991, offers a compelling account of feminism being forced to repeat itself in an era hostile to its transformative potentials and ambitions. Twenty years on, this paper offers a philosophical reading of Faludi's text, unpacking the model of social and historical change that underlies the “backlash” thesis. It focuses specifically on the tension between Faludi's ideal model of social change as a movement of linear, step-by-step, continuous progress, and her depiction of feminist history in (...) terms of endless repetition. If we uphold a linear, teleological ideal of social change, I argue, repetition can only be thought of in negative terms—as a step backwards or a waste of time—which in turn has a negative and demoralizing impact within feminism itself. To explore an alternative model of historical time and change, I turn to the work of feminist philosopher Christine Battersby, who rethinks repetition through the Kierkegaardian mode of “recollecting forwards,” and the Nietzschean notion of “untimeliness.” I suggest that Battersby's philosophical reconceptualization of historical repetition, as a potentially creative, productive phenomenon, can be of great utility to feminists as we enact and negotiate the dynamics of backlash politics.

It has been argued recently that one major difficulty facing the A-theory of time consists in the view’s failure to provide a satisfactory account of the passage of time. Critics have objected that this particular charge is premised on an unduly strong conception of temporal passage, and that the argument does not go through on alternative, less demanding conceptions of passage. The resulting dialectical stalemate threatens to prove intractable, given the notorious elusiveness of the notion of temporal passage. (...) Here I argue that there is progress to be made in this regard. The argument from passage takes issue with a certain feature of the standard versions of the A-theory that is in fact problematic independently of worries about temporal passage. To illustrate this, I present a new argument, the argument from comprehensiveness, which demonstrates that the standard A-theoretic account of temporal reality is inadequate, even if it is granted that it can accommodate passage.

The diaries that detail Ernst Jünger’s time in occupied Paris can be as frustrating as they are captivating. Their tone is often both elegiac and detached, at once keenly aware of and distant from the suffering occurring all around their author. This ambiguity becomes particularly apparent in the contrast between the remarkable everyday encounters the diaries describe and their broader cosmic and world-historical ruminations. In this paper, I want to suggest that this tension can be read as a response to (...) the imperatives through which totalising thought shapes how subjects operating under its confines relate to time itself. This dynamic, which can already be found in Jünger’s own earlier work, is dramatized in the way that the diaries construct the alternative temporal perspective of the witness. The witness here is one who survives outside of, and yet also remains caught between, two temporal imaginaries characteristic of modernity: Totalising historicization – the sweeping narrative of progress that demands the sacrifice of the present individual and individual present – and mechanised temporality, that is, instrumentalised clock time.

Before the twentieth century, the Universe was usually imagined as a large spatially extended thing unfolding in time. The past was fixed and the future was open; unfolding was conceived as an asymmetric process of coming into being. Relativity introduced a new vision in which space and time are presented together as a single four-dimensional manifold of events. That, together with the fact that the fundamental laws of our classical theories are symmetric in time, made understanding why the past and (...) future present themselves so differently in our experience one of the central challenges of physics. The last two centuries have seen a great deal of progress in understanding various of the so-called arrows of time: the thermodynamic arrow, the cosmological arrow, the arrow of knowledge or information. There remains an outstanding piece of this puzzle that has seen little progress, one that Roger Penrose described in his beautiful paper Singularities and Time-Asymmetry in 1979 as: “The arrow most difficult to comprehend … namely the feeling of relentless forward temporal progression, according to which potentialities seem to be transformed into actualities.”I will propose that the insight needed to resolve the problem involves taking into account that we are part of the universe and that any attempt to model it as a totality involves self-reference. I will argue specifically that self-reference, against the background of a thermodynamic gradient, creates an instability in an embedded agent’s ability to know the future or even treat it as a potential object of knowledge. That instability captures the sense in which the future remains for her perpetually open and the passage of time resolves openness into the fixity of fact. (shrink)

ExcerptIt can be argued that we are currently living in a time characterized by a widespread perception of “discontinuity,” of a rupture in historical continuity. This rupture appears to have been brought about by the alleged demise of the secular paradigm, underpinning the Enlightenment project of modernity, caused by the outbreak of religious fervor and spirituality at the dawn of the new millennium. The perceived rupture in the natural progression of secular modernity has led to the questioning of the (...) assumed link of modernity and secularity1 and to the critique of Enlightenment theories and postulates regarding the disenchantment of the….

Attention to the role of phenomenology in Frantz Fanon’s Black Skin, White Masks is fundamental to an appreciation of the book’s progressive structure. And it is through an appreciation of this structure that it becomes apparent that the book’s engagement with phenomenology amounts to an enrichment, not a critique, of existential phenomenology, although the latter might appear to be the case at first sight, given Fanon’s rejection of certain aspects of Jean-Paul Sartre’s “Black Orpheus.” This is demonstrated through an examination (...) of Fanon’s references to Sartre, Günther Anders, and Maurice Merleau-Ponty in the book’s final crucial pages on temporality. His largely neglected relation to Karl Jaspers and the concept of historicity is also explored. (shrink)

Primary progressive aphasia is a clinical syndrome in which patients progressively lose speech and language abilities. Three variants are recognized: logopenic, associated with phonology and/or short-term verbal memory deficits accompanied by left temporo-parietal atrophy; semantic, associated with semantic deficits and anterior temporal lobe atrophy; non-fluent associated with grammar and/or speech-motor deficits and inferior frontal gyrus atrophy. Here, we set out to investigate whether the three variants of PPA can be dissociated based on error patterns in a single language task. (...) We recruited 21 lvPPA, 28 svPPA, and 24 nfvPPA patients, together with 31 healthy controls, and analyzed their performance on an auditory noun-to-verb generation task, which requires auditory analysis of the input, access to and selection of relevant lexical and semantic knowledge, as well as preparation and execution of speech. Task accuracy differed across the three variants and controls, with lvPPA and nfvPPA having the lowest and highest accuracy, respectively. Critically, machine learning analysis of the different error types yielded above-chance classification of patients into their corresponding group. An analysis of the error types revealed clear variant-specific effects: lvPPA patients produced the highest percentage of “not-a-verb” responses and the highest number of semantically related nouns ; in contrast, svPPA patients produced the highest percentage of “unrelated verb” responses and the highest number of light verbs. Taken together, our findings indicate that error patterns in an auditory verb generation task are associated with the breakdown of different neurocognitive mechanisms across PPA variants. Specifically, they corroborate the link between temporo-parietal regions with lexical processing, as well as ATL with semantic processes. These findings illustrate how the analysis of pattern of responses can help PPA phenotyping and heighten diagnostic sensitivity, while providing insights on the neural correlates of different components of language.

For men of the 19th century, the world was ordered by a whole system of concrete universals: ideals and the empirical world were simply two aspects of the same reality; ideals described an empirical reality which included them as its actual cohesive power. This character is reflected in the fact that the most influential thinkers of the last century combined, despite the rise of the specialized disciplines, sociological, historical and philosophical approaches to a reality which in social, temporal, and (...) cosmic aspects they conceived to be homogeneous. This unity has been dissolved in 20th century thought. The results of sociological and historical investigations of social reality have undermined the absolute validity of ideals. Epistemology has tended to undermine the meaningfulness of the objective world. Even so, attempts to revivify the old ideals by re-synthesizing ideas and existence are still being made. Historicism has been continuously concerned with its own Ueberwindung by the establishment of an absolute value; sociology has continued to search for general meanings, whether in the form of a sociology of knowledge or the culture-dynamics of a Sorokin; philosophy has concentrated its attention upon existence or experience or process: and the prominence of the philosophy of history and of philosophy as history which these developments imply are testimony of the tendency to replace nature by man so that man is the arena in which the re-integration of the different levels of reality is to be sought. Values which took a hard and fast form in the connection between general idea and particular existence in the 19th century have been disengaged through dissociation. The examination of historical and social experience and ideas in their own terms has made possible a new assessment of what is essential and what contingent in the general concepts of western man. At the same time even the subsequent integrative procedure, i.e. the historizing of ideas and the philosophizing of experience, has contributed further to such an assessment by including as the necessary basis for thought all of man's history and experience within its purview.

This study examines the linguistic construal and cognitive representation of time and viewpoint in the genre of news narratives. We present a model of mental spaces that involves a News Space in which the deictic center is construed of the news actors at the time the newsworthy events took place, and a Reality Space in which the deictic here-and-now center of journalist and reader is construed. This model explains how the dynamic representation of narrative news discourse, characterized by shifts in (...) time and viewpoint, is steered by linguistic devices. An analysis of Dutch news narratives shows that temporal adverbs such as yesterdayand shifts from present tense to past tense may signal a moveforwardin narrative time, to a viewpoint in the future relative to the narrative now-point, rather thanbackward. These atypical time shifts can be accounted for by presupposing an Intermediate Space located at a point in time between the News Space and the Reality Space where the progression of narrative time comes to a halt and experiences are rather relived than reported. The salience of the Intermediate Space may be signaled by quotative conditionals reflecting the viewpoints of implicitly quoted sources. These results clarify how tense and temporal deixis steer the linguistic construal of time and viewpoint in news narratives, demonstrating that time and viewpoint are closely linked in the cognitive representation of these narratives.

We present a completeness proof for Propositional Interval Temporal Logic with finite time which avoids certain difficulties of conventional methods. It is more gradated than previous efforts since we progressively reduce reasoning within the original logic to simpler reasoning in sublogics. Furthermore, our approach benefits from being less constructive since it is able to invoke certain theorems about regular languages over finite words without the need to explicitly describe the associated intricate proofs. A modified version of regular expressions called (...) Fusion Expressions is used as part of an intermediate logic called Fusion Logic. Both have the same expressiveness as PITL but are lower-level notations which play an important role in the hierarchical structure of the overall completeness proof. In particular, showing completeness for PITL is reduced to showing completeness for Fusion Logic. This in turn is shown to hold relative to completeness for conventional linear-time temporal logic with finite time. Logics based on regular languages over finite words and!-words offer a promising but elusive framework for formal specification and verification. A number of such logics and decision procedures have been proposed. In addition, various researchers have obtained complete axiom systems by embedding and expressing the decision procedures directly within the logics. The work described here contributes to this topic by showing how to exploit some interesting links between regular languages and interval-based temporal logics. (shrink)

Past and future coalesce in discussions of LGBTI rights, often embedded in narratives of progress, civilisation, colonisation and emancipation. An understanding of these dynamics can help to illuminate the complex power relations that currently striate international LGBTI rights discourses. This paper analyses how temporality operates in the context of international LGBTI rights through an examination of the World Bank’s withdrawal of a $90 million loan to Uganda after the passage of the Anti-Homosexuality Act 2014. To do this, the paper juxtaposes (...) postcolonial critiques of the ongoing international legal reproduction of the colonial encounter, with a Deleuzian conception of law’s ‘virtual memory’. These two theoretical lenses are used to show how attempts to advance LGBTI rights can reproduce problematic civilisational binaries, through which the Global North seeks to manage the unruly or ‘uncivilized’ Global South. These civilisational and spatial dichotomies are often obscured by un-interrogated ‘grand narratives’ of progress and by the codification of specific, narrow forms of rights protections. As such, the paper argues that in order to better advance current and future frameworks for sexual orientation and gender identity justice, we must undertake a more attentive encounter with the past.

Ultradian rhythms are those that cycle many times in a day and are therefore measured in hours, minutes, seconds or even fractions of a second. In yeasts and protists, a temperature‐compensated clock with a period of about an hour (30–90 minutes) provides the time base upon which all central processes are synchronized. A 40‐minute clock in yeast times metabolic, respiratory and transcriptional processes, and controls cell division cycle progression. This system has at its core a redox cycle involving NAD(P)H (...) and dithiol–disulfide interconversions. It provides an archetype for biological time keeping on longer time scales (e.g. the daily cycles driven by circadian clocks) and underpins these rhythms, which cannot be understood in isolation. Ultradian rhythms are the foundation upon which the coherent functioning of the organism depends. BioEssays 29:465–473, 2007. © 2007 Wiley Periodicals, Inc. (shrink)
