While linear time results from the measurement of physical events, the temporality of life is characterized by cyclical processes, which also manifest themselves in subjective bodily experience. This applies for the periodicity of heartbeat, respiration, sleep-wake cycle, or circadian hormone secretion, among others. The central integration of rhythmic bodily signals in the brain forms the biological foundation of the phenomenal sense of temporal continuity. Cyclical repetitions are also found in the recurring phases of need, drive, and satisfaction. Finally, the (...) cyclical structure of bodily time manifests itself at an extended level in the form of implicit or body memory. However, this cyclical structure of lived time comes into tension with the orders of linear time which have been increasingly established in Western societies since the modern age. This tension creates both individual as well as societal conflicts and may also result in psychopathological phenomena. As an example, depression and burn-out syndromes will be discussed. (shrink)

We present a Hilbert style axiomatisation for the set of formulas in the temporal language with F and P which are valid over non-transitive cyclical flows of time. We also give a simpler axiomatisation using the slightly controversial 'irreflexivity rule' and go on to prove the decidability of any temporal logic over cyclical time provided it uses only connectives with first-order tables.

Penrose's conformal cyclic cosmology describes the cosmos as a collection of successive universes, the so-called aeons. The beginning and ending of our universe are directly connected to two other, anterior and posterior, universes. Penrose considers but rules out a different interpretation of conformal cyclic cosmology: that the beginning of our universe is connected to its own end in a cosmic loop. The paper argues that the view, aeon monism, should be regarded as a natural interpretation of conformal (...) class='Hi'>cyclic cosmology and discusses its implications for the concept of eternal return in light of the most popular metaphysics of time.

Cyclic mechanic is intended as a suitable generalization both of quantum mechanics and general relativity apt to unify them. It is founded on a few principles, which can be enumerated approximately as follows: 1. Actual infinity or the universe can be considered as a physical and experimentally verifiable entity. It allows of mechanical motion to exist. 2. A new law of conservation has to be involved to generalize and comprise the separate laws of conservation of classical and relativistic mechanics, (...) and especially that of conservation of energy: This is the conservation of action or information. 3. Time is not a uniformly flowing time in general. It can have some speed, acceleration, more than one dimension, to be discrete. 4. The following principle of cyclicity: The universe returns in any point of it. The return can be only kinematic, i.e. per a unit of energy (or mass), and thermodynamic, i.e. considering the universe as a thermodynamic whole. 5. The kinematic return, which is per a unit of energy (or mass), is the counterpart of conservation of energy, which can be interpreted as the particular case of conservation of action “per a unit of time”. The kinematic return per a unit of energy (or mass) can be interpreted in turn as another particular law of conservation in the framework of conservation of action (or information), namely conservation of wave period (or time). These two counterpart laws of conservation correspond exactly to the particle “half” and to the wave “half” of wave-particle duality. 6. The principle of quantum invariance is introduced. It means that all physical laws have to be invariant to discrete and continuous (smooth) morphisms (motions) or mathematically, to the axiom of choice. The list is not intended to be exhausted or disjunctive, but only to give an introductory idea. (shrink)

Examines the relationship between time and sexual difference in the work of French feminists Julia Kristeva and Luce Irigaray. This book is the first to examine the relationship between time and sexual difference in the work of Julia Kristeva and Luce Irigaray. Because of their association with reproduction, embodiment, and the survival of the species, women have been confined to the cyclical time of nature—a temporal model that is said to merely repeat itself. Men, on the other (...) hand, have been seen as bearers of linear time and as capable of change and progress. Fanny Söderbäck argues that both these temporal models make change impossible because they either repeat or repress the past. The model of time developed here—revolutionary time—aims at returning to and revitalizing the past so as to make possible a dynamic-embodied present and a future pregnant with change. Söderbäck stages an unprecedented conversation between Kristeva and Irigaray on issues of both time and difference, and engages thinkers such as Simone de Beauvoir, Jacques Derrida, Sigmund Freud, Judith Butler, Hannah Arendt, and Plato along the way. “Revolutionary Time makes a distinctive contribution to contemporary feminist and continental philosophical thought. By engaging Kristeva and Irigaray in depth alongside one another, and making time the guiding thread for reading their work, the author generates insights that are not to be found elsewhere in the existing literature. Through its development of the concept of revolutionary time, the book offers rich resources for thinking about temporalization in its existential, ontological, and political dimensions, in ways that are particularly valuable for feminist projects of change and political transformation.” — Rachel Jones, author of Irigaray: Towards a Sexuate Philosophy.

Relativistic models of an expanding universe followed by contraction, or a big bang followed by a big crunch, were first proposed by A. Friedmann in 1922 and nine years later by A. Einstein. In the period ca. 1922–1960, the more speculative idea of a large and possibly infinite number of cycles was discussed by R. Tolman in particular. To some cosmologists, the idea was philosophically appealing because it seemed to justify an eternal yet dynamic universe without an absolute beginning in (...) time. During the 1950s models of this kind, sometimes known as Phoenix models, were investigated by a few cosmologists of whom the most important were A. Dauvillier, W. Bonnor, and H. Zanstra. (shrink)

In the post-Soviet context, various cyclical models of recurrent Russian “Times of Troubles” have become increasingly popular. This perspective emerged first in Soviet dissident circles, who used it as a means to expose as mistaken the Soviet belief in continual historical progress on Russian soil. In post-Soviet Russia this critical approach has been continued by members of the “Akhezier circle,” the economist Egor Gaidar, and others. Meanwhile it was given an affirmative, conservative reinterpretation by Aleksandr Panarin, according to whom Russia (...) has always managed to overcome its phases of devastating Westernization and state collapse. This idea of Russian history has become influential; even Vladimir Putin has talked about Russia as a strong state able to survive various “Times of Troubles” from the early seventeenth century to the early post-Soviet period. It also figures prominently among members of the neoconservative Izborsk Club. This article analyzes different conceptions of Russian history as cyclical and their prominent place in the prevailing civilizational discourse of post-Soviet Russia. By means of postcolonial perspectives, this discourse is seen on the one hand as an attempt to question and reject Western hegemony, attempts that on the other hand nevertheless seem unable to liberate themselves from a normative dependence on the West.

Time as the key to a theory of everything became recently a renewed topic in scientific literature. Social constructivism applied to physics abandons the inevitable essentials of nature. It adopts uncertainty in the scope of the existential activity of scientific research. We have enlightened the deep role of social constructivism of the predetermined Newtonian time and space notions in natural sciences. Despite its incompatibility with determinism governing the Newtonian mechanics, randomness and entropy are inevitable when negative localized energy (...) is transformed into spatially dissipative heat. In sharp contrast to the Newtonian notion, social constructivism makes room for the temporal twin of cyclic conservation and pseudo-linearly structural evolution both reconciling mechanical order and thermodynamic chaos in Leibnizian space-time. In the broad scope of natural sciences this triad nature of time produces a multiple reality and gives appropriate answers on virtual physical paradoxes. (shrink)

To formally understand cyclicity in innovation and to tie to Schumpeter’s idea about waves of creative destruction, we elaborate upon Thomas Kuhn’s (1962) hypothesis that science evolves through a succession of paradigm life cycles by noting that entrepreneurs recognize the profitability of new scientific theories through a delay. The delay from innovation to entrepreneurship may be due to technological inertia, the time taken in recognizing the applications of basic research, or related to how quickly technological change evolves over (...) class='Hi'>time and its returns are realized. In our model, a profit-maximizing entrepreneur uses the latest scientific knowledge to create innovative technologies, which generates cycles between science and innovation. The necessary conditions for the existence of cycles are that human capital employed in science creation and high valued innovations is high, and the interest rate is low. The findings also tie to the notion about the variability of innovation over the business cycle and can provide useful inputs into the formulation of more effective technology policies. (shrink)

The Chinese view of time and history cannot be defined as either “cyclicality” or “linearity” in the sense of St. Augustine and Hegel. Like the Indo-Hellenic cyclicality, it regards the cyclical movements as universal in both Heaven and human. Nevertheless, it contains neither the conception of Great Year or Mahayuga, nor that of repeated destruction and reconstruction of humankind. It holds that the cyclical movements do not recur as “uniform rotation,” but appear as a chain composed of countless links (...) each of which possesses individuality. It is not the chain itself, but each of its links that cyclically develop. Meanwhile, it agrees with the Judeo-Christian tradition that there is no repetition and reversibility for historical figures and events. However, it does not believe that history has an absolute beginning and end, demonstrating itself as a One-Grand Cycle from human alienation from God to their reconciliation with Him. (shrink)

Visit the author's Web site at www.11PicsOfTime.com Time is a mystery that has perplexed humankind since time immemorial. Resolving this mystery is of significance not only to philosophers and physicists but is also a very practical concern. Our perception of time shapes our values and way of life; it also mediates the interaction between science and religion both of which rest fundamentally on assumptions about the nature of time. C K Raju begins with a critical exposition (...) of various time-beliefs, ranging from the earliest times through Augustine, Newton and Einstein to Stephen Hawking and current notions of chaos and time travel. He traces the role of organised religion in subverting time beliefs for its political ends. The book points out how this resulted in a facile dichotomy between 'linear' and 'cyclic' time, thereby inaugurating a confusion which, according to the author, has handicapped Western thought ever since, eventually influencing the content of science itself. Thus, this book daringly asserts that physical theory, traditionally regarded as amoral and objective, has depended on cultural beliefs about time. The author points out that time beliefs are again being manipulated today as the credibility of science is being exploited to promote a picture of time and, hence, a pattern of human behaviour which is convenient to the agenda of globalisation of culture. The linkages between modern theology and this 'brave new physics' are traced against the wider context of the so-called 'clash of civilisations', and the attempts to remake the world order. The conclusions point to the need to de-theologise time. The author challenges Einstein's understanding of relativity theory and suggests that a 'tilt in the arrow of time', or a small tendency towards cyclicity, will help repair the prevalent confusion about time. A 'tilt' also enables a physics that permits both memory and creativity, so that purpose and spontaneous growth of order are returned to human life. The book ends with a vision of Man as Creator, surprising God. Extensive research in physics, the history of science, comparative religions, and sociology lend weight to the important and challenging conclusions reached by the author. Written as a rejoinder to Stephen Hawking's A Brief History of Time, this book goes much further and, unlike any previous book, it gives a critical exposition of various world religions-Buddhism, Christianity, Hinduism, Islam, and Jainism-while exploring their intricate links, through time beliefs, to current physics on the one hand, and to global political and economic trends, on the other. This book will appeal to scholars and laypersons equally. It will fascinate anyone who reads it and will teach its readers to question the unquestionable. (shrink)

The perception of time shifts as patients enter hospice care. As a complex, socially determined construct, time plays a significant role in end‐of‐life care. Drawing on Buddhist and Western perspectives, conceptualizations of linear and cyclical time are discussed alongside notions of time as interplay of embodied experience and concept. Buddhist understandings of self as patterns of relating and the theory of ‘dependent origination’ are introduced. Implications for understanding death, dying and end‐of‐life care within these differing perspectives (...) are considered. These explorations contribute to the growing dialogue in nursing between Buddhist and Western traditions. (shrink)

The article reveals the deep connection of artistic time and emotional system of the cinematic work, viewed as a model of the nonequilibrium dynamic process. The author analyzes forms of time – specifically linear and cyclical time – that participate in the creation of tragic catharsis. She further shows that different artistic modes – heroic, tragic, comic, idyllic, elegiac, dramatic, ironic – can be realized in artworks through the specific temporal forms corresponding to them.

In this paper I will explore a phenomenology of the menstrual cycle, focusing on the cycle’s rhythm as a form of lived temporality. Drawing on the work of Henri Lefebvre and Thomas Fuchs I will outline a key connection between embodiment and rhythmic temporality more generally, before applying this analysis to the rhythm of the menstrual cycle specifically. I will consider the phenomenology of the experience of cycling through the phases of pre-ovulation, ovulation, pre-menstruation and menstruation as a pattern, or (...) specifically an embodied rhythm that constitutes a form of lived temporality. I will consider a way that the subject may potentially be alienated from this rhythm as a result of a dominant cultural narrative of “linear time”. I will argue further that this dissonance between the menstrual body and the contemporary world tends to be compounded by a lack of “menstrual literacy” in education and culture. (shrink)

This article attempts to foreground the importance of everyday life and habit to the reproduction of national identities. Taking issue with dominant linear depictions of the time of the nation, which have over-emphasized ‘official’ histories, tradition and heroic narratives, this article foregrounds the everyday rhythms through which a sense of national belonging is sustained. The article focuses upon institutionalized schedules, habitual routines, collective synchronicities and serialized time-spaces to develop an argument that quotidian, cyclical time is integral to (...) national identity. In conclusion, accounts that discuss the increasing dominance of a postmodern global time are argued to be hyperbolic, since the nation remains a powerful, if more flexible constituent of identity.

Theories of the nature of time offered by anthropology, science, and religion are not only numerous but also very different. This groundbreaking book cuts through the confusion by introducing a provocative new tripolar model of time that integrates the human, natural, and religious dimensions of time into a single, harmonious whole. Wolfgang Achtner, Stefan Kunz, and Thomas Walter begin by exploring the structures of time in anthropological terms. They discuss time phenomenologically, showing how it can (...) be experienced in three distinct ways -- the mythic-cyclic, the rational-linear, and the mystic-holistic -- and they root these experiences in the findings of modern neuroscience and trace these three forms of the perception of time within various cultures of antiquity. The second part of the book looks at time as it has been described by some of sciences most profound theories, including classical mechanics, the special and general theories of relativity, quantum mechanics, thermodynamics, and chaos theory. The authors then bring religion into the equation by surveying how time is conceived in both the Hebrew Bible and the Christian New Testament. They distinguish time concepts in wisdom and apocalyptic literature from time concepts in prophetic literature, and they demonstrate the basic eschatological orientation of the Christian view of time. "Dimensions of Time culminates by tying together the various strands of the authors' multidisciplinary, tripolar model of time. Offering a fascinating application of their unique theory, Achtner, Kunz, and Walter show how the unhealthy acceleration of life in contemporary society needs to be balanced by a rediscovery ofthe mystical experience of time, leading to a greater, deeper sense of human fulfillment.

Purpose: To reawaken the consciousness of all Africans to the implications of the metaphysical trajectory of time in Africa, which John S. Mbiti presents, in relation to personal and collective human development in Africa. Methodology: This work is expository, critical, and evaluative in its methodology. Findings: In Western thought, there is mathematical and linear time, as dominant ideas. Dominant because some philosophers, in particular Bergson, have their notion of time as mainly inclined to be lived, organic. It (...) is linear time in the sense that, it is an imagined line through which the distant past, present and infinite future is figured. Linear time as such does not exist, but it is a metaphysical notion existing in our minds. Linear time is unidirectional and mathematical. In Africa, African Philosophy is still fledgling. That is, it is not fully developed and documented. Consequently, even the field of “time” lacks a robust written commentary. Unique Contribution to theory, practice and policy (recommendation): Within the traditional African milieu, according to Mbiti, time is a two dimensional phenomenon, with a long past, a present and virtually no future. This is contrary to the linear time concept in western thought, with an indefinite past, present and future. This work is expository, analytical and critical in its methodology. The first part of the discussion is concerned with the nature of time (and its constituent elements) as a metaphysical concept. The second part focuses on the ordering of time as found among the Africans. Finally, the third part discusses some of the different activities (in customs and traditions), which point to the future. These include the meaning of life, rites of passage, painting and divination, etc. In the conclusion, a fundamental question is raised regarding, whether or not, the present organization of time, in Africa, as presented by John S. Mbiti, be perpetuated or changed, taking into account the pros and cons it bears. (shrink)

Personal time, as opposed to external time, has a certain role to play in the correct account of death and immortality. But saying exactly what that role is, and what role remains for external time, is not straightforward. I formulate and defend accounts of death and immortality that specify these roles precisely.

Unemployment is not just an economic category but is constituted by governmentality, most evidently by the increase of interventions into the lives of the unemployed through Active Labour Market Policies. Furthermore, the International Labour Organization definition of unemployment as being without work, available for work and seeking work is a shifting classification which categorises unemployment on multiple temporal horizons, with the passive element of being without work increasingly superseded by the emphasis on seeking work. Through biographical interviews with unemployed in (...) Ireland, spanning from 2012-2018, we trace this transformation of temporality empirically and conclude that governmentality constitutes multiple, contradictory, indefinite forms of time. Particularly, we offer an imaginative reading of two overlapping temporalities: Kairos, waiting, enduring, suffering nothingness in anticipation of transformation by getting a job, and Cronos, not cyclical time, but the devouring of time, where the days and leisure of the unemployed people are deliberately consumed by job-seeking. Ironically, states implement ALMPs in the kairotic hope of transforming their economy, yet these policies do little but make the experience of unemployment even harder to endure. (shrink)

This metatheoretical paper investigates mind wandering from the perspective of philosophy of mind. It has two central claims. The first is that, on a conceptual level, mind wandering can be fruitfully described as a specific form of mental autonomy loss. The second is that, given empirical constraints, most of what we call “conscious thought” is better analyzed as a subpersonal process that more often than not lacks crucial properties traditionally taken to be the hallmark of personal-level cognition - such as (...) mental agency, explicit, consciously experienced goal-directedness, or availability for veto control. I claim that for roughly two thirds of our conscious life-time we do not possess mental autonomy (M-autonomy) in this sense. Empirical data from research on mind wandering and nocturnal dreaming clearly show that phenomenally represented cognitive processing is mostly an automatic, non-agentive process and that personal-level cognition is an exception rather than the rule. This raises an interesting new version of the mind-body problem: How is subpersonal cognition causally related to personal-level thought? More fine-grained phenomenological descriptions for what we called “conscious thought” in the past are needed, as well as a functional decomposition of umbrella terms like “mind wandering” into different target phenomena and a better understanding of the frequent dynamic transitions between spontaneous, task-unrelated thought and meta-awareness. In an attempt to lay some very first conceptual foundations for the now burgeoning field of research on mind wandering, the third section proposes two new criteria for individuating single episodes of mind-wandering, namely, the “self-representational blink” (SRB) and a sudden shift in the phenomenological “unit of identification” (UI). I close by specifying a list of potentially innovative research goals that could serve to establish a stronger connection between mind wandering research and philosophy of mind. (shrink)

Originally published in 1980. What is time? How is its structure determined? The enduring controversy about the nature and structure of time has traditionally been a diametrical argument between those who see time as a container into which events are placed, and those for whom time cannot exist without events. This controversy between the absolutist and the relativist theories of time is a central theme of this study. The author's impressive arguments provide grounds for rejecting (...) both these theories, firstly by establishing that 'empty' time is possible, and secondly by showing, through a discussion of the structure of time which involves considering whether time might be cyclical, branching, beginning or non-beginning, that the absolutist theory of time is untenable. This book then advances two new theories, and succeeds in shifting the traditional debate about time to a consideration of time as a theoretical structure and as a theoretical framework. (shrink)

The genesis of space and time is investigated within the rotational-monadic paradigm. It is established that the essence of the phenomenon of space is revealed through the dialectical synthesis of its two aspects — ideal and material, where the material aspect is represented by the metaphysical construct of protomonad. It is shown that basic physical distinctions such as motion, mass, gravitation find a meaningful hermeneutic through the material aspect of space, which has a purely discrete structure, while the contradiction (...) about finitude — infinity is resolved by juxtaposing metaphysical and ontic spaces, where the Universe is represented as an “egg”. The analysis of temporality is preceded by remarks on the relational and substantive concepts of time, consideration of the discreteness-continuity dilemma, and criticism of the absolutization of discreteness in the temporality representation. It is argued that discreteness and continuity are combined dialectical oppositions through which the temporal reality is actualized, where continuity is hidden from observation in the metaphysical world and discreteness is manifested explicitly in the physical world. Three dimensions of time — Present, Past and Future — are discussed, as a result of which it is stated that in the primary way time is found as an attribute of consciousness and only in the secondary way it correlates with phenomenological reality. New differentiations of time are revealed: interval Present, embracing as a universum other moduses of the Present, and two- component time in the form of cyclic and linear components which allow us to make a justified positive conclusion about the existence of transcendental subjectivity, being the basis of absolute temporality.

Since its first publication, A Study of Time in Indian Philosophy has been acclaimed as having successfully shown •the simple falsityê of such clich_s that the Indian view of time is •cyclicê or that it is exclusively •illusoryê. Given the variety of views discussed in this work, it is evident that the theme of time is intimately related to such basic concepts as being and becoming, change and causality, creation and annihilation. It has been therefore, observed that (...) this book makes an excellent introduction to the heart of Indian thought. Based on Sanskrit source material, this book is a unique attempt to presenting a comprehensive review of the widely divergent views about time in Indian thought. Clearly written, it succeeds in setting out the issues of discussion pointedly and cogently. Since the concept of time intervenes with such major concepts as that of causality, being and non-being etc., this book also –serves as a general introduction to the classic heart of Indian Philosophy.” The author –has demonstrated a rare ability to translate technical doctrines from one tradition of thought into the language of another”, and thus has made it possible- for all those who are concerned with the question of time but do not have access in the Indian conceptual world to appreciate the contributions of Indian thought with regard to this complex question. Noteworthy is the fact that this book is the first attempt which –successfully exposes the simple falsity” of such cliches as that the Indian view of time is •cyclic as opposed to the Judaeo-Christian understanding of linear time. A Study of Time in Indian Philosophy, therefore, renders a valuable service to all those who are concerned with cross-cultural and inter religious exchange. (shrink)

For Vajrayana Buddhism, the now is an interval, a boundary, a point of tension and suspension with an atmosphere of uncertainty. It is a bifurcation point of variable length; its name is “bardo.” The bardo is immersed in the conventional, or “seeming” reality. It emerges from what is called the “unstained” ultimate or primordial emptiness or “basal clear light.” Further, the ultimate is not the sphere of cognition. Cognition, including cognition of time, belongs to conventional reality. Buddhahood, in contrast, (...) is a condition of uncompounded knowledge where basic mind blossoms without temporal or other cognitive distinctions, unmade, unfabricated, luminous and pristine. Cyclical existence involves both the ultimate and the conventional as it moves through six bardos—all of which are the effulgent of the basal clear light—until Buddhahood. The six are: the bardo of this life ; the bardo of dream; the bardo of meditation; the bardo of dying; the bardo of dharmata ; and the bardo of existence. Each realm is both ultimate and conventional, and has specific initiation-based yogas to investigate these differences. The process of transition from one to the next involves at least three bodies, one mind, and aspects of speech. In each bardo, the character of the now as embodiment and temporal knowing varies yet a complete and consistent cross-bardo yogic wisdom leads to its total cessation in the basal clear light; the now is extinguished. The author presents, from the viewpoint of a knowledgeable practitioner of over 30 years, an essay on Vajrayana Buddhist time, drawing implications for Fraser’s time typology. The essay will draw from English translations of significant older, tantric texts on dream yoga, deity yoga, the Chod, tantric time, the bardo of death, and empowerment. Useful practices that can be applied by the audience to test the tradition and author’s assertions will be suggested. (shrink)

This paper explores the relationship of time and value in the history of economics, using the contributions of Girard, Achterhuis, Kula and Mirowski. In the ‘anthropometric stage’ time and value are intertwined: value and time are not abstract concepts, but they express a concrete process which incorporates the social positions of individuals. In the ‘lineamentric stage’ the concepts of time and value remain cyclical, but they receive an abstract character. The economy reproduces itself cyclically, because the (...) origin of value – human labour – reproduces itself in each production period. In the ‘syndetic stage’ the cyclical conception of the economy is abandoned through the perception of a non-reproductive system. Time and value are detached from each other, and linear time enters economic theory as an analytical tool. The labour theory of value is replaced by external denominants of value: utility and external scarcity. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Time and History in Alois Riegl's Theory of PerceptionMichael GubserIn an early essay, the Austrian art historian Alois Riegl (1858–1905), a pioneer of the modern discipline of art history, linked the creation of the zodiac images in calendar art to the designation of constellations in the heavens.1 Ancient calendar artists observed the motion of stars across the night sky and attempted to map them into recognizable patterns representing (...) specific temporal periods. Their efforts inscribed the cyclical temporality of the heavens into the images of the ancient calendar. This inherent temporality came to characterize all art forms in Riegl's work; his choice of calendar art as his earliest research topic heralded a career-long interest in the connection between temporality and artistic form. Art objects, he believed, were temporal as well as spatial. Just as the light from constellations reflected a deep history, artworks illuminated the passage of time by visually re-presenting the perceptual world of past eras.Riegl's work has garnered attention in recent decades among art historians and non–art historians alike. This interest is due in part to the renewed concern for disciplinary origins that art history, like other fields, has experienced in the wake of poststructuralist critiques. Scholars outside of art history have taken note of his work because of its broad scope and relevance for the study of historiography and perception; Riegl's work provides models for linking the analysis of specific artworks with a history of perception, exploring the relationship between monuments and memory, and analyzing the nature of visual modernity. Interest in Riegl also stems from his acknowledged impact on such preeminent philosophers and historical theorists as Erwin Panofsky, Paul Feyerabend, Gilles Deleuze, Fèlix Guattari, and above all Walter [End Page 451] Benjamin.2 Figures as varied as Georg Lukács, Karl Mannheim, Walter Gropius, and Mikhail Bakhtin have cited his work favorably.3 Riegl is perhaps best known for his attempts to dismantle the hierarchy of high and low art, his attack on the preeminence of classical aesthetic ideals, and his effort to construct a universal history of style. The combination of these commitments led him to consider European and non-European craft genres that fell outside conventional definitions of art. In books such as Problems of Style, Late Roman Art Industry, and The Group Portraiture of Holland, Riegl examined the high arts, decorative arts, and manufactured artifacts alike, gleaning insights into the structure of an era's perception from close descriptive analyses of its artwork.4 In Problems of Style, Riegl traced the development of ancient vegetal decorative motifs toward their fulfillment in the naturalized tendrils and acanthus leaves of Greek ornament. A single, universal development encompassed seemingly distinct motivic forms, and creative innovation was driven by an inner formal logic. Similarly, Late Roman Art Industry, the [End Page 452] epoch-making work that Walter Benjamin described as a revolution in art historical method,5 traced the gradual development of space as an object of artistic concern in the late Roman Empire. In this volume, Riegl explored his controversial notion of the Kunstwollen, or artistic will, which asserted art's autonomy on the basis of a formal creative volition internal to artworks.6 Finally, The Group Portraiture of Holland documented the emergence and decline of a "typically Hollandish painting" emphasizing space and attention.7Riegl scholars have frequently attempted to situate his art history within a variety of philosophical traditions, an effort complicated by Riegl's limited citation of sources. Several scholars have linked Riegl's historical vision with the embattled tradition of Hegelian philosophy. Riegl's teleology; his stress on the unified, internal, and purposive development of art; his notion of art as mind overcoming material; and even his emphasis on the role of the viewer in art all have a distinctly Hegelian resonance. Wolfgang Kemp fits Riegl squarely within a late-nineteenth-century Hegelian revival,8 Michael Podro incorporates him within a Hegelian critical tradition of art history that spanned the nineteenth and early twentieth centuries,9 and Michael Ann Holly posits a clear trajectory, linking Kant and Hegel with Riegl and Panofsky.10Others, however, just as firmly reject this...

The COVID-19 pandemic has foregrounded the significance of time to everyday life, as the routines, pace, and speed of social relations were widely reconfigured. This article uses rhythm as an object and tool of inquiry to make sense of spatio-temporal change. We analyse the Mass Observation (MO) directive we co-commissioned on ‘COVID-19 and Time’, where volunteer writers reflect on whether and how time was made, experienced, and imagined differently during the early stages of the pandemic in the (...) UK. We draw on Henri Lefebvre and Catherine Régulier's ‘rhythmanalysis’, taking up their theorisation of rhythm as linear and cyclical and their concepts of arrhythmia (discordant rhythms) and eurhythmia (harmonious rhythms). Our analysis highlights how MO writers articulate (a) the ruptures to their everyday rhythms across time and space, (b) their experience of ‘blurred’ or ‘merged’ time as everyday rhythms are dissolved and the pace of time is intensified or slowed, and (c) the remaking of rhythms through new practices or devices and attunements to nature. We show how rhythm enables a consideration of the spatio-temporal textures of everyday life, including their unevenness, variation, and difference. The article thus contributes to and expands recent scholarship on the social life of time, rhythm and rhythmanalysis, everyday life, and MO. (shrink)

In these two lectures, first published in 1994, Peter Diamond explores how time is modelled in theoretical analyses of individual industries and of an entire economy. In the first lecture he considers equilibrium in a single market by examining the distinction between the short run and the long run in Marshallian analysis. He proposes an explicit modelling of time in place of Marshall's use of different atemporal models for different time frames. In the second lecture he turns (...) to models of an entire economy, and begins by considering how and why models of an entire economy should differ from models of a single industry. Both cyclical and seasonal data on the behaviour of macro-economies are examined. (shrink)

This wide ranging discourse covers many disciplines of science and the human condition in an attempt to fully understand the manifestation of time. Time's Paradigm is, at its inception, a philosophical debate between the theories of 'Presentism' and 'The Block Model', beginning with a pronounced psychological analysis of 'free will' in an environment where the past and the future already exist. It lays the foundation for the argument that time is a cyclical, contained progression, rather than a (...) meandering voyage into infinity, bringing into question the validity of a commensurate 'Big Bang'. Following, the proposal widens to encompass physics. It tackles clock rates and time dilation, acausality and the nuisance of a universal clock, and demonstrates that conscious consideration creates the present moment - time's flow - separating the solid state past and future whose reality is devoid of space. Arguments relating to Quantum Physics theory, including the Uncertainty Principle and a Superposition of States, lend credibility to key areas involving cognitive awareness. It is posited that defined points in time and space prohibit progress in linear models for progression. Thus motile paradoxes can be resolved with the absence of infinities; temporal perception, it is concluded, being the result of uncertainty. Time's Paradigm takes the bold step of asking us to consider a tangible dimension of time, representing an intimate extension of our three, known spatial dimensions. Chaos theory is briefly introduced leading to the configuration of a fractal fourth dimension of time whose assumption demands only one direction of flow. Further, it asks whether our universe is expanding or contracting. It considers the simple physics of bodies contracting in a fourth dimension of time (UC), and how that marries comfortably with standard scientific models such as Special Relativity. The rate at which matter is contracting in the universe is illustrated in a reduction factor of 1.618... coinciding with Fibonacci's Ratio and countering Time Dilation. Lastly the more complex aspects of relativistic velocities are tackled together with the conundrum of Zero Velocity and The Speed of Light being attributes of the same event in Cyclical Space-Time, and ultimately, the prospect of superluminal velocities by interaction with parallel time-zones in a multi-layered block universe.

Professor Lucas has written what is perhaps the most trenchant, sophisticated, and comprehensive treatise on time and space to have appeared in a long while. The book is distinguished not only by its acute treatment of the mathematical and physical concepts constituting its subject but also by a meditative quality all too rare in philosophical works dealing with the unquestionably fundamental and complex themes of time and space. The book is a phenomenology or morphology of time and (...) space in that it is a foundational analysis of the philosophical, mathematical, physical, logical, and theological aspects of our understanding of these concepts. The work is organized into five general sections each of which is internally refined with a keen sense of what is essential to the particular context of discussion. The first section investigates "Time by Itself" through reference to such notions as instant and interval, the topology and direction of time, cyclic time, permanence and omni-temporality, and the mathematical ideas of denseness and continuity.

We present an algorithm to infer causal relations between a set of measured variables on the basis of experiments on these variables. The algorithm assumes that the causal relations are linear, but is otherwise completely general: It provides consistent estimates when the true causal structure contains feedback loops and latent variables, while the experiments can involve surgical or `soft' interventions on one or multiple variables at a time. The algorithm is `online' in the sense that it combines the results (...) from any set of available experiments, can incorporate background knowledge and resolves conflicts that arise from combining results from different experiments. In addition we provide a necessary and sufficient condition that determines when the algorithm can uniquely return the true graph, and can be used to select the next best experiment until this condition is satisfied. We demonstrate the method by applying it to simulated data and the flow cytometry data of Sachs et al. (shrink)

This article reflects on important terms and concepts that constitute the cosmology of the Yijing: ji, tian, yin-yang , and the correlative aspects of temporality. These are familiar terms from the Yijing as well as other philosophical texts from ancient China. It begins with a comparative inquiry into Chinese and Greek attitudes toward time and then explores the related philosophical consequences. Although the ancient Chinese view of the world as temporal, processual, and relational may be found to be in (...) contrast with Greek substance-oriented philosophy, it is argued here that we should revise some commonly accepted interpretations of Chinese terms. Without adequate reflection on temporality and process, many important terms may be misconstrued as atemporal and substance-oriented, which would be alien to the sensibilities of East Asian traditions. Thus, it is attempted here to gauge the adequacy of the prominent existing interpretations of these terms and ideas while giving an account of how such interpretations may be revised to better recognize the role of temporality and process. Specifically, it is proposed that the interpretations given here accord best with a conception of time as a spiral trajectory, as opposed to either the cyclic or linear conceptions of time usually considered dominant in the Yijing and ancient Chinese philosophy.

Previous research suggests that both patterns in orthography and cultural-specific associations of space-time affect how people map space onto time. In the current study, we focused on Chinese Buddhists, an understudied population, investigating how religious experiences influence their mental representations of time. Results showed that Chinese Buddhists could represent time spatially corresponding to left-to-right, right-to-left and top-to-bottom orientations in their religious scripts. Specifically, they associated earlier events with the starting point of the reading and later times (...) with the endpoint. We also found that Chinese Buddhists were more likely to represent time in a clockwise way than Chinese atheists. This is because Buddhism regards time as cyclic and consisting of repeating ages (i.e. Wheel of Time). Taken together, we provide first psychological evidence that Chinese Buddhists’ spatial representations of time are different from atheists’, due to their religious experiences, namely, both the reading direction in Buddhist texts and Buddhist concepts of time.

This study of Western philosophic systems, their types, history, relations, and projected future in the next half century, stems from Robert S. Brumbaugh’s forty-year fascination with the paradox of the many consistent overarching systems of ideas that are nevertheless mutually exclusive. Brumbaugh argues that when we isolate these systems’s patterns and look at them more abstractly, they consistently fall into four main types, and the interaction of these four types of explanation and order is a dominant theme in the history (...) of Western philosophy. In Brumbaugh’s view these four philosophic systems are not, as some critical historians and thinkers have claimed, so different that they are mutually unintelligible, forcing us to make a choice among them that is entirely arbitrary. But neither are they, as a majority of past thinkers and historians have hoped, simply parts of some single "right" or "orthodox" scheme. Their mutual understanding requires a method of transformation that interprets one to another without destroying their diversity. The history of Western philosophy from the fifth century A.D. to the present shows a pattern of alternating revolutions in systematic method and direction of explanation. Brumbaugh feels that the pattern is continuing in a change toward a revised Platonism, just beginning with the twenty-first century. He anticipates that it will be a Platonism of a new texture, one that has matured and learned a great deal in the course of the adventures of its ideas through space and time. (shrink)

The concepts of biblical time and history were unique in the ancient world and were adopted by western civilization. In the Hebrew Bible, there is a straight line of movement from the story of creation, Adam, Abraham and the Covenant, Exodus to the concept of the Messiah. This linear history is continued in the New Testament in the story of Jesus as the Messiah, his life and death, and the concept of the second coming of the Messiah. For the (...) Bible as a whole, each event is unique; there is no repetition. Time is real and the story moves forward in time, Professor Konvitz argues. From their early philosophers and historians to the Stoics, Greek thinkers believed in the cyclical nature of time and history, with some arguing for reincarnation and others, prototypical social scientists, seeing repetition of patterns in human behavior.

This article investigates the differential structure and representation of time in memory and history. It examines two moments in Jewish historical thought--in the Middle Ages, and in works written within and after the Holocaust--and demonstrates the fundamentally liturgical nature of Jewish historical memory in selected texts from these two periods. Following the groundbreaking work of Yerushalmi, it seeks to demonstrate that for Jews, historical experience is incorporated into the cyclical reenactment of paradigmatic events in Jewish sacred ritual. Recent or (...) contemporary experiences acquire meaning only insofar as they can be subsumed within Biblical categories of events and their interpretation bequeathed to the community through the medium of Scripture, that is to say, only insofar as they can be transfigured, ritually and liturgically, into repetitions and reenactments of ancient happening. In such liturgical commemoration, the past exists only by means of recitation; the fundamental goal of such recitation is to make it live again in the present, to fuse past and present, chanter and hearer, into a single collective entity. History, in the sense that we understand it to consist of unique events unfolding within irreversible linear time, is absorbed into cyclical, liturgical memory.This article argues that the question of Jewish history--both medieval and post-Holocaust--poses in a compelling fashion the question of the relationship between memory and history more generally, and serves to contest the current tendency in academic historiography to collapse history into memory. It claims that to the extent that memory "resurrects," " re-cycles," and makes the past "reappear" and live again in the present, it cannot perform historically, since it refuses to keep the past in the past, to draw the line, as it were, that is constitutive of the modern enterprise of historiography.

Possibly the most fundamental scientific problem is the origin of time and causality. The inherent difficulty is that all scientific theories of origins and evolution consider the existence of time and causality as given. We tackle this problem by starting from the concept of self-organization, which is seen as the spontaneous emergence of order out of primordial chaos. Self-organization can be explained by the selective retention of invariant or consistent variations, implying a breaking of the initial symmetry exhibited (...) by randomness. In the case of time, we start from a random graph connecting primitive “events”. Selection on the basis of consistency eliminates cyclic parts of the graph, so that transitive closure can transform it into a partial order relation of precedence. Causality is assumed to be carried by causal “agents” which undergo a more traditional variation and selection, giving rise to causal laws that are partly contingent, partly necessary. (shrink)

This article concerns the problem of time pressures in higher education from the perspective of Newtonian (clock)time and pedagogical action. While most recent critiques of contemporary time pressures turn to alternative time theories in place of Newtonian temporality, the current paper outlines a way to conceive education from a Newtonian time perspective while also retaining theorizations of education as a form of cyclical and uncertain interaction. Time is theorized as changes in the immediate present (...) which transform an uncertain and potential future to an evident and permanent past in a Newtonian-linear temporal framework. Education, on the other hand, is defined as pedagogical influence to foster student’s human growth, demonstrated in a teaching–studying–learning relationship. Slow education theories and strategies are proposed as a way to reclaim time for education from the accelerative time policies of HE from within a linear time perspective instead of having to propose alternative time theories to ‘free’ education from its rootedness in the temporality of past, present, and future.

Our earliest tools are our bodies. Our hands raise and turn and toss and carry and push and pull, our legs walk and climb and kick allowing us to move and act in the world and to create the multitude of artifacts that improve our lives. The list of actions made by our hands and feet and other parts of our bodies is long. What is more remarkable is we turn those actions in the world into actions on thought through (...) gestures, language, and graphics, thereby creating cognitive tools that expand the mind. The focus here is gesture; gestures transform actions on perceptible objects to actions on imagined thoughts, carrying meaning with them rapidly, precisely, and directly. We review evidence showing that gestures enhance our own thinking and change the thought of others. We illustrate the power of gestures in studies showing that gestures uniquely change conceptions of time, from sequential to simultaneous, from sequential to cyclical, and from a perspective embedded in a timeline to an external perspective looking on a timeline, and by so doing obviate the ambiguities of an embedded perspective. We draw parallels between representations in gesture and in graphics; both use marks or actions arrayed in space to communicate more immediately than symbolic language. (shrink)

In this work we extend approximate aggregation methods in time discrete linear models to the case of time varying environments. Approximate aggregation consists in describing some features of the dynamics of a general system involving many coupled variables in terms of the dynamics of a reduced system with a few number of variables. We present a time discrete time varying model in which we distinguish two time scales. By using perturbation methods we transform the system (...) to make the global variables appear and build up the aggregated system. The asymptotic relationships between the general and aggregated systems are explored in the cases of a cyclically varying environment and a changing environment in process of stabilization. We show that under quite general conditions the knowledge of the behavior of the aggregated system characterizes that of the general system. The general method is also applied to aggregate a multiregional time dependent Leslie model showing that the aggregated model has demographic rates depending on the equilibrium proportions of individuals in the different patches.
