The overt oviposition rhythm ofLymnaea stagnalis should be regarded as an endogenous one. Despite considerable deviations of its period from 24 hrs, entrainment by 24 hr. external periodicities is possible. Possibly, entrainment is effectuated via a second — covert — internal rhythm. The fact that similar rhythms have not been established before, is probably connected with the nature of the phenomena to which previous studies have generally been limited.

Previous chapter In her book Die Form des Werdens: Eine Kulturgeschichte der Embryologie, 1760-1830, Janina Wellmann claims that around 1800 the concept of rhythm has emerged and penetrated the entire Western culture. In literature, in theoretical reflection on art, in philosophy, but especially in the newest life sciences, rhythm would have become a common scientific “Paradigm” or better yet, a new “Episteme”. It would be great if it is true. But I think - Sur le concept de rythme (...) – Nouvel article. (shrink)

Genetic analysis is revealing molecular components of circadian rhythms. The gene products of the period gene in Drosophila and the frequency gene in Neurospora oscillate with a circadian rhythm. A recent paper(1) has shown that the PERIOD protein can undergo both intermolecular and intramolecular interactions in vitro. The effects of temperature and two period mutations on these molecular interactions were compared to the effects of the mutations and temperature on the in vivo period length of (...) circadian rhythms. The results suggest that the molecular interactions may compete to maintain a rhythm with a constant period over a wide temperature range. (shrink)

The literature on social interactions has shown that participants coordinate not only at the behavioral but also at the physiological and neural levels, and that this coordination gives a temporal structure to the individual and social dynamics. However, it has not been fully explored whether such temporal patterns emerge during interpersonal coordination beyond dyads, whether this phenomenon arises from complex cognitive mechanisms or from relatively simple rules of behavior, or which are the sociocultural processes that underlie this phenomenon. We review (...) the evidence for the existence of group-level rhythmic patterns that result from social interactions and argue that the complexity of group dynamics can lead to temporal regularities that cannot be predicted from the individual periodicities: an emergent collective rhythm. Moreover, we use this interpretation of the literature to discuss how taking into account the sociocultural niche in which individuals develop can help explain the seemingly divergent results that have been reported on the social influences and consequences of interpersonal coordination. We make recommendations on further research to test these arguments and their relationship to the feeling of belonging and assimilation experienced during group dynamics. (shrink)

In higher eukaryotes, circadian behaviour patterns have been dissected at the molecular level in Drosophila and, more recently, in the mouse. Considerable progress has been made in identifying some of the molecular components of the clock in the fly, where two genes, period (per) and timeless (tim), are essential for behavioural rhythmicity. The PER and TIM proteins show circadian cycles in abundance, and are part of a negative feedback loop with their own mRNAs. Within the pacemaker neurons, the PER (...) and TIM products are believed to form a complex which allows them to translocate to the nucleus, but how they repress their own transcription is unclear. TIM is rapidly degraded by light, a feature which permits a compelling molecular description of both behavioural light entrainment and phase responses to light pulses. The regulation of per and tim is altered in different Drosophila tissues, however, and comparative analyses of the two genes outside the Diptera reveals further unusual patterns of tissue‐specific regulation. Evolution appears to have modified the way in which the two genes are utilised to generate circadian phenotypes. More recently, the cloning of mouse clock genes, including putative per homologues, opens up exciting possibilities for mammalian molecular chronobiology. (shrink)

In writing on a subject in which the most significant words have been used in quite different senses by modern authors, I think it most prudent to begin by defining my terms. By rhythmical prose I mean all prose in which the writer consciously follows a definite scheme in order to obtain particular cadences at the close of the period or within it, and this whether the favoured cadences are marked by quantity or by accent. I subdivide rhythmical prose (...) into metrical and accentual. The latter term explains itself. In spite of Aristotle's familiar opposition of ṕÅθμóσ and μτρ¿ν, I use the word ‘metrical’ of quantitative prose, both because the term ‘quantitative prose’ seems to me cumbrous, and because to the speakers of any modern language metre is the natural opposite of stress accent, whether in prose or in verse; and Aristotle's terminology, which takes no account of stress accent, may reasonably be displaced by the modern distinction.

What is the broadest significance of musical rhythm? Human attitudes to the world are reflected in it, according to Gustav Becking. Writing in the 1920s, Becking proposed a novel method of finding systematic differences of attitude between individual composers, between nations, and between historical time periods. He dealt throughout with Western classical music, from the period approximately 1600-1900. His method was to observe in fine detail the pattern of motion and pressure traced out by a small baton allowed (...) to move in sympathy with a given musical excerpt. The various patterns arising for individual composers were represented graphically, and in that form became known as -Becking curves-. Implications were touched upon in psychology, sociology and philosophy. His thesis is now published in English translation from the original German for the first time, with many annotations.".

Isochrony is crucial to the rhythm of human music. Some neural, behavioral and anatomical traits underlying rhythm perception and production are shared with a broad range of species. These may either have a common evolutionary origin, or have evolved into similar traits under different evolutionary pressures. Other traits underlying rhythm are rare across species, only found in humans and few other animals. Isochrony, or stable periodicity, is common to most human music, but isochronous behaviors are also found (...) in many species. It appears paradoxical that humans are particularly good at producing and perceiving isochronous patterns, although this ability does not conceivably confer any evolutionary advantage to modern humans. This article will attempt to solve this conundrum. To this end, we define the concept of isochrony from the present functional perspective of physiology, cognitive neuroscience, signal processing, and interactive behavior, and review available evidence on isochrony in the signals of humans and other animals. We then attempt to resolve the paradox of isochrony by expanding an evolutionary hypothesis about the function that isochronous behavior may have had in early hominids. Finally,we propose avenues for empirical research to examine this hypothesis and to understand the evolutionary origin of isochrony in general. (shrink)

Mutations that disrupt biological rhythms have existed in microbial and metazoan eukaryotes for some time. They have recently begun to be studied with increasing intensity, both in terms of phenotypic effects of the relevant genetic variants, and with regard to molecular isolation and analysis of the genes defined by two of the ‘clock mutations’. These genetic loci, called period (per) in Drosophila and frequency (frq) in Neurospora, influence not only the basic characteristics of circadian rhythmicity, but also temperature compensation (...) of such daily cycle durations, ‘re‐setting’ of the rhythms' phases, and (for the per mutants) behavioral oscillations associated with much shorter than circadian periodicities. Molecular cloning of Drosophila's per gene, accompanied crucially by the locus's identification in germ‐line transformants, has led to information on its expression ‐ temporally, spatially, and in regard to heterogeneity of mRNA types. Nucleotide‐sequencing analyses of genomic DNA (and/or cDNA) from normal and mutated per alleles have (1) led to the suggestion that this clock gene encodes a family of proteoglycans (which was further indicated by application of antibody reagents obtained by manipulation of one of the gene's exons); and (2) shown that the three types of per mutations ‐ which shorten or lengthen rhythm periodicities or appear to eliminate them ‐ are associated with interesting amino‐acid substitutions or a stop codon, respectively. Analogous molecular findings are awaited from Neurospora, whose frq gene has very recently been cloned and definitively identified, in part via transformation experiments. (shrink)

The marine ecosystem is governed by a multitude of environmental cycles, all of which are linked to the periodical recurrence of the sun or the moon. In accordance with these cycles, marine species exhibit a variety of biological rhythms, ranging from circadian and circatidal rhythms to circalunar and seasonal rhythms. However, our current molecular understanding of biological rhythms and clocks is largely restricted to solar‐controlled circadian and seasonal rhythms in land model species. Here, we discuss the first molecular data emerging (...) for circalunar and circatidal rhythms and present selected species suitable for further molecular analyses. We argue that a re‐focus on marine species will be crucial to understand the principles, interactions and evolution of rhythms that govern a broad range of eukaryotes, including ourselves. (shrink)

Historians have often described embryology and concepts of development in the period around 1800 in terms of “temporalization” or “dynamization”. This paper, in contrast, argues that a central epistemological category in the period was “rhythm”, which played a major role in the establishment of the emerging discipline of biology. I show that Caspar Friedrich Wolff’s epigenetic theory of development was based on a rhythmical notion, namely the hypothesis that organic development occurs as a series of ordered rhythmical (...) repetitions and variations. Presenting Christian Heinrich Pander’s and Karl Ernst von Baer’s theory of germ layers, I argue that Pander and Baer regarded folding as an organizing principle of ontogenesis, and that the principle’s explanatory power stems from their understanding of folding as a rhythmical figuration. In a brief discussion of the notion of rhythm in contemporary music theory, I identify an underlying physiological epistemology in the new musical concept of rhythm around 1800. The paper closes with a more general discussion of the relationship between the rhythmic episteme, conceptions of life, and aesthetic theory at the end of the eighteenth century. (shrink)

A wide range of biological processes, in all eukaryotes and in some prokaryotes, are controlled by rhythms with a period close to 24 hours. The circadian oscillator, which is responsible for generating these rhythms, is controlled by light signals that maintain its synchrony with the environmental day/night cycle. Higher plants exhibit many circadian rhythms, including rhythms in the transcription of specific genes. Molecular tools derived from such clock‐controlled genes have led to the identification of several circadian rhythm mutants (...) in the genetic model, Arabidopsis thaliana. The extensive understanding of photoperception in this species will make it a powerful system with which to investigate the light regulation of circadian rhythms. We compare Arabidopsis rhythms to the results from other systems, and discuss these data with respect to the current phototransduction models. (shrink)

Thanks to genetic and biochemical advances on the molecular mechanism of circadian rhythms in Drosophila, theoretical models closely related to experimental observations can be considered for the regulatory mechanism of the circadian clock in this organism. Modeling is based on the autoregulatory negative feedback exerted by a complex between PER and TIM proteins on the expression of per and tim genes. The model predicts the occurrence of sustained circadian oscillations in continuous darkness. When incorporating light‐induced TIM degradation, the model accounts (...) for damping of oscillations in constant light, entrainment of the rhythm by light‐dark cycles of varying period or photoperiod, and phase shifting by light pulses. The model further provides a molecular dynamical explanation for the permanent or transient suppression of circadian rhythmicity triggered in a variety of organisms by a critical pulse of light. Finally, the model shows that to produce a robust rhythm the various clock genes must be expressed at the appropriate levels since sustained oscillations only occur in a precise range of parameter values.

Aristotle distinguishes two types of style, the ‘periodic’ or ‘rounded’ and the ‘non-periodic’, ‘strung-on’ or ‘continuous’ .* The latter is typical of prose in its young and unsophisticated state, and Aristotle is not much interested in it; his discussion of the periodic style is much longer, with subdivisions being introduced and numerous examples given. His basic definition of the period is not, however, clear, and the point has seen some controversy. There are two possibilities. He defines the period (...) ‘rhythmically’ . The essential feature of the period is that its beginning and end are marked off by specific metrical rhythms .1 He defines it ‘logically’. The period is a syntactic structure with an inner cohesion produced by the logical, pre-planned arrangement of its parts according to the requirements of the whole.2 The current consensus at least of written opinions is that Aristotle intended the first;3 I believe that the issue can be settled fairly decisively in favour of the second.

Daniel Bensaïd was prominent among the revolutionary thinkers and activists who emerged from the mass insurgency of the 1960s, a period in which anti-capitalist organisers had genuine social weight grounded in connections to broad layers of the working class and radical movements. As the neoliberal offensive developed, working-class and allied movements experienced crucial defeats that marginalised anti-capitalist theory and practice. Bensaïd developed a unique theoretical analysis of radical mobilising during the neoliberal period, at once grounded in the history (...) of revolutionary organising and audaciously open-ended in assessing the impact of capitalist restructuring and the employers’ offensive. The basis of his theoretical renewal lay in a new approach to understanding temporality that undercut any sense of socialist inevitability, and a commitment to revolutionary pluralism that was crucially located in the political sphere.

A number of popular theories about trauma have suggested rhythm has potential as a mechanism for regulating arousal levels. However, there is very little literature examining this proposal from the perspective of the young people who might benefit. This action research project addresses this gap by collaborating with four groups of children in the out-of-home-care system to discover what they wanted from music therapists who brought a strong focus on rhythm-based activities. The four music therapy groups took place (...) over a 12 month period and each cycle of action and reflection led to adjustments in what activities were offered, as well as exploring different levels of structure and ways of building relationships in the groups. The initial group incorporated a strong emphasis on highly structured rhythm-based activities, but young people found the format difficult to engage with. The second cycle included more opportunities for creativity and self-direction within semi-structured activities which children reported enjoying, but too much freedom also became overwhelming at times. The two groups in the third cycle seemed to balance structure and responsiveness successfully but were also influenced by the introduction of individual sessions prior to group commencement, which was designed to contribute to safety and trust building. Final reflections on the role of rhythm in supporting young people who have had adverse experiences were centred around the ideas of co-regulation. This was qualitatively different to our expectations that practicing rhythm-based activities would lead to an expanded window of tolerance that resulted in less time being spent in either hypo-arousal or hyper-arousal. Instead of entraining to an external rhythm, young people felt safe when their rhythms were matched, even if they were irregular, out of time and unpredictable. The small moments of co-regulation resulted in pleasure, comfort, satisfaction and peace and these moments were highly valued by the young people, who described just wanting to be relaxed and happy. Although not as rhythm-specific as the literature might suggest, music making with trusted adults helped the young people in this study feel more content. (shrink)

[The Mechanics of Sorcery in the Context of Deceptive-Imitative Poetry] When we inquire as to how people could have a perverted preference for ignorance over knowledge, Plato’s statement that people are deprived of true opinions only against their will provides us with an essential clue for starting out: Depriving a person of something against their will is only possible by theft, by spells of sorcery, or by force. Victims of sorcery alter their opinions under the spell of pleasure or are (...) terrified by fear. However, the “sorcery” mentioned here is not a mysterious effect, but rather the deterioration of the harmony established between the three aspects of the soul in favor of appetite. The measure and harmony in the cosmos apply to the fundamental principles of the human soul, and rhythm is engraved on the soul as the protector of measure and harmony. Rhythmic speech is the reflection of “divine language” in the human world; the poet of the ancient period was the interpreter of the “sacred language” through which the divine word appeared. When the poet and the poetry both degenerate, the poet is reduced to nothing more than a common diviner or sorcerer. Since he knows nothing but how to imitate, he embellishes his work with colors from ancient arts. He speaks his words in rhythm, measure, and harmony in order to deceive reason, which is the aspect of our soul that is most prone to measurement and calculation. This is how the poet paralyzes it. Therefore, imitative poetry vitiates our soul “without even our souls hearing it”. (shrink)

Integration of knowledge concerning circadian rhythms, metabolic networks, and sleep‐wake cycles is imperative for unraveling the mysteries of biological cycles and their underlying mechanisms. During the last decade, enormous progress in circadian biology research has provided a plethora of new insights into the molecular architecture of circadian clocks. However, the recent identification of autonomous redox oscillations in cells has expanded our view of the clockwork beyond conventional transcription/translation feedback loop models, which have been dominant since the first circadian period (...) mutants were identified in fruit fly. Consequently, non‐transcriptional timekeeping mechanisms have been proposed, and the antioxidant peroxiredoxin proteins have been identified as conserved markers for 24‐hour rhythms. Here, we review recent advances in our understanding of interdependencies amongst circadian rhythms, sleep homeostasis, redox cycles, and other cellular metabolic networks. We speculate that systems‐level investigations implementing integrated multi‐omics approaches could provide novel mechanistic insights into the connectivity between daily cycles and metabolic systems. -/- .

Synchronized movements with external periodic rhythms, such as dancing to a beat, are commonly observed in daily life. Although it has been well established that some vocal learning species (including parrots and humans) spontaneously develop this ability, it has only recently been shown that monkeys are also capable of predictive and tempo-flexible synchronization to periodic stimuli. In our previous study, monkeys were trained to make predictive saccades for alternately presented visual stimuli at fixed stimulus onset asynchronies (SOAs) to obtain a (...) liquid reward. The monkeys generalized predictive synchronization to novel SOAs in the middle of trained range, suggesting a capacity for tempo-flexible synchronization. However, it is possible that when encountering a novel tempo, the monkeys might sample learned saccade sequences from those for the short and long SOAs so that the mean saccade interval matched the untrained SOA. To eliminate this possibility, in the current study we tested monkeys on novel SOAs outside the trained range. Animals were trained to generate synchronized eye movements for 600 and 900-ms SOAs for a few weeks, and then were tested for longer SOAs. The accuracy and precision of predictive saccades for one untrained SOA (1200 ms) were comparable to those for the trained conditions. On the other hand, the variance of predictive saccade latency and the proportion of reactive saccades increased significantly in the longer SOA conditions (1800 and 2400 ms), indicating that temporal prediction of periodic stimuli was difficult in this range, similar to previous results on synchronized tapping in humans. Our results suggest that monkeys might share similar synchronization mechanisms with humans, which can be subject to physiological examination in future studies. (shrink)

We investigate the long-term evolution of degree-degree correlations (assortativity) in functional brain networks from epilepsy patients. Functional networks are derived from continuous multi-day, multi-channel electroencephalographic data, which capture a wide range of physiological and pathophysiological activities. In contrast to previous studies which all reported functional brain networks to be assortative on average, even in case of various neurological and neurodegenerative disorders, we observe large fluctuations in time-resolved degree-degree correlations ranging from assortative to dissortative mixing. Moreover, in some patients these fluctuations (...) exhibit some periodic temporal structure which can be attributed, to a large extent, to daily rhythms. Relevant aspects of the epileptic process, particularly possible pre-seizure alterations, contribute marginally to the observed long-term fluctuations. Nevertheless, our findings suggest that physiological and pathophysiological activity may modify functional brain networks in a different and process-specific way. We evaluate factors that possibly influence the long-term evolution of degree-degree correlations. (shrink)

We address how listeners perceive temporal regularity in music performances, which are rich in temporal irregularities. A computational model is described in which a small system of internal self‐sustained oscillations, operating at different periods with specific phase and period relations, entrains to the rhythms of music performances. Based on temporal expectancies embodied by the oscillations, the model predicts the categorization of temporally changing event intervals into discrete metrical categories, as well as the perceptual salience of deviations from these categories. (...) The model's predictions are tested in two experiments using piano performances of the same music with different phrase structure interpretations (Experiment 1) or different melodic interpretations (Experiment 2). The model successfully tracked temporal regularity amidst the temporal fluctuations found in the performances. The model's sensitivity to performed deviations from its temporal expectations compared favorably with the performers' structural (phrasal and melodic) intentions. Furthermore, the model tracked normal performances (with increased temporal variability) better than performances in which temporal fluctuations associated with individual voices were removed (with decreased variability). The small, systematic temporal irregularities characteristic of human performances (chord asynchronies) improved tracking, but randomly generated temporal irregularities did not. These findings suggest that perception of temporal regularity in complex musical sequences is based on temporal expectancies that adapt in response to temporally fluctuating input. (shrink)

We present evidence disputing the hypothesis that memories are processed or consolidated in REM sleep. A review of REM deprivation (REMD) studies in animals shows these reports to be about equally divided in showing that REMD does, or does not, disrupt learning/memory. The studies supporting a relationship between REM sleep and memory have been strongly criticized for the confounding effects of very stressful REM deprivation techniques. The three major classes of antidepressant drugs, monoamine oxidase inhibitors (MAOIs), tricyclic antidepressants (TCAs), and (...) selective serotonin reuptake inhibitors (SSRIs), profoundly suppress REM sleep. The MAOIs virtually abolish REM sleep, and the TCAs and SSRIs have been shown to produce immediate (40–85%) and sustained (30–50%) reductions in REM sleep. Despite marked suppression of REM sleep, these classes of antidepressants on the whole do not disrupt learning/memory. There have been a few reports of patients who have survived bilateral lesions of the pons with few lingering complications. Although these lesions essentially abolished REM sleep, the patients reportedly led normal lives. Recent functional imaging studies in humans have revealed patterns of brain activity in REM sleep that are consistent with dream processes but not with memory consolidation. We propose that the primary function of REM sleep is to provide periodic endogenous stimulation to the brain which serves to maintain requisite levels of central nervous system (CNS) activity throughout sleep. REM is the mechanism used by the brain to promote recovery from sleep. We believe that the cumulative evidence indicates that REM sleep serves no role in the processing or consolidation of memory. Key Words: antidepressant drugs; brain stem lesions; dreams; functional imaging; memory consolidation; REM deprivation; REM sleep; theta rhythm. (shrink)

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.

Daily rhythms are a ubiquitous feature of living systems. Generally, these rhythms are not just passive consequences of cyclic fluctuations in the environment, but instead originate within the organism. In mammals, including humans, the master pacemaker controlling 24‐hour rhythms is localized in the suprachiasmatic nuclei of the hypothalamus. This circadian clock is responsible for the temporal organization of a wide variety of functions, ranging from sleep and food intake, to physiological measures such as body temperature, heart rate and hormone release. (...) The retinal circadian clock was the first extra‐SCN circadian oscillator to be discovered in mammals and several studies have now demonstrated that many of the physiological, cellular and molecular rhythms that are present within the retina are under the control of a retinal circadian clock, or more likely a network of hierarchically organized circadian clocks that are present within this tissue.

Period homeostasis is the defining characteristic of a biological clock. Strict period homeostasis is found for the ultradian clocks of eukaryotic microbes. In addition to being temperature-compensated, the period of these rhythms is unaffected by differences in nutrient composition or changes in other environmental variables.

That process philosophy can be the foundation of the theory and practice of educating human beings is the main argument of this book. The process philosophy of Alfred North Whitehead (1861-1947) is the particular thinking on which this book is based. Readers are shown that Whitehead's process philosophy provides a frame, a conceptual matrix, that addresses their concerns about education and offers direction for their educative acts. Whitehead theorized that all living entities are connected in some way. Relatedness, connectedness, and (...) holism are recurring themes in this exploration of Whitehead's implied philosophy of education. Whitehead never wrote a philosophy of education, but his writings over a period of nearly thirty years reveal a persistent interest and concern with education. His work, ranging from _Introduction to Mathematics_ (1911) to _Adventures of Ideas_ (1938), is drawn on here to construct, not Whitehead's philosophy of education, but, a Whiteheadian philosophy of education. _Whitehead and Philosophy of Education_ brings to scholars and students of education an understanding of Whitehead as an important figure in philosophy, particularly philosophy of education; an acquaintance with process philosophy; a brief treatment of Whitehead's life and an account of events and experiences that influenced his philosophizing; and an exploration of the educationally salient concepts found in Whitehead's formal and informal philosophy with special attention to Whitehead's ideas about creativity, process, rhythm, wisdom, and knowledge. Whitehead writes of phases of the rhythm of education - romance, precision, and generalization. The book is organized with attention to these three phases. Part One-Romance introduces readers to Whitehead the person, and the change of context for educating from a mechanistic world-view to an organismic one. Part Two-Precision examines Whitehead's writings, as they relate to process philosophy and to educating. Part Three-Generalization is an application of the explorations of Parts One and Two, yielding a construction of a Whiteheadian philosophy of education and suggestions for educational practice.

1 Introduction1 In the 1980s, hermeneutics was often incorporated into deconstructionism and literary theory. Rather than focus on authorial intentions, the nature of writing itself including codes used to construct meaning, socio-economic contexts and inequalities of power,2 Gadamer introduced a different perspective; the interplay between effects of history on a reader’s understanding and the tradition(s) handed down in writing. This interplay in which a reader’s prejudices are called into question and modified by the text in a fusion of understanding and (...) topic revitalized the study of the printed word. Gadamer’s turn to language for understanding the meaning of Being also appealed to the post-modern antipathy toward modernity and metaphysics.3 If the truth and validity of interpretations are limited to communities of language, then our mode of being in history cannot but be historical. This point of view rendered Gadamer’s phenomenological hermeneutics vulnerable to the critique of moral and epistemological relativism. However, Gadamer’s theory of interpretation also stems from re-examination of the beginning of knowledge in the Pre-Socratics and Plato, and on this basis, is receptive to another dimension of inquiry than that which was trending in North America. -/- At the East-West Center, University of Hawai’i at Manoa in 1982, Chung-ying Cheng for the first time introduced onto-hermeneutics to an audience of esteemed philosophers including Li Zehou, Ren Jiyu, Feng Youlan, and Zhang Liwen.4 In contrast to schools of deconstruction and literary theory that had disengaged the interpreter from trans-historical sources of meaning and truth, Cheng explained that interpreters exist within a cosmological order inextricable from responsibility to harmonize Heaven and Earth in creative acts of interpretation. By integrating Chinese cosmology into hermeneutics through ontology, he tacitly challenged philosophers in the West to re-examine assumptions about humanity’s place in nature and by implication, Gadamer’s recovery of the beginnings of knowledge in Western philosophy. -/- Cheng’s Neo-Confucianism is inspired by the method and goals of Thomé H.

The following words by Fang seem to prefigure, although in an indistinct and bundled way, aspects of Cheng’s philosophy including a Mencian theory of human nature, comprehensive observation, and creativity: “In the very process of living in concord with creative Nature, Man is charged with an ideal to be fully realized in the light of the principle of comprehensive harmony.”5 Like Fang, Cheng reinvigorates Chinese culture and language, but not solely in order to vindicate the insights of Neo-Confucianism. He has studied Western thought, from pragmatism and the analytic school to German idealism and phenomenology, to unlock and clarify philosophical concepts within the Yijing tradition and thereby render them intelligible to Anglophones. The result has been an awakening of Western scholars to the moral and cultural consequences of decoupling their thought from metaphysical foundations that are neither dogmatic nor doctrinal. -/- Not unlike the dialectic of Gadamer’s dialogue form, onto-generative hermeneutics integrates contrary positions on the same topic in order to blend both sides into a world philosophy, or as Cheng says, a “totalizing or integrative theory,”6 not to be confused with a theoretical rewording of a theory. On the contrary, the universal scope and relevance of hermeneutics stems from personal experience. Just as Gadamer, in response to faction and strife, immersed himself in Plato during the war years, and developed a method with which to harmonize opposites, so too, according to On-cho Ng, was Cheng moved by faction, strife and political persecution to develop a path toward unity.7 Gadamer taught at McMaster University in Hamilton, Ontario, and Cheng at the University of Hawai’i at Manoa among other institutions in North America. They facilitated trans-continental educational and cultural ties. Similar experiences yield similar insights irrespective of differences of time and place. Hence, authors in this issue who reside in Europe, China and North America, delineate the differences between Gadamer and Cheng, yet also, in light of Cheng’s onto-generative method and cosmology, develop integrative theories. Due to the page-budget restriction of the publisher, certain articles of this special theme will be subsequently published in the next issue. -/- 2 Integrative Theory This special issue of The Journal of Chinese Philosophy confirms a dimension of hermeneutics that Cheng has both motivated and inspired. The contributors do not abide by the conviction that since thought is mediated by language, interpretations cannot transcend culture. On the contrary, their research exemplifies the fruits of trans-historical onto-dialogical hermeneutics within limits defined by their field inquiry, organized into Parts I and II, around three themes: language, the philosophy of history and ethics. -/- Andrew Fuyarchuk introduces the theme of ontology in relation to Gadamer’s turn to language. Fuyarchuk argues that Chung-ying Cheng’s criticism of Gadamer’s hermeneutics is informed by Heidegger’s concept of Dasein and thereby overlooks how Gadamer’s Platonic-Pythagorean problem of the division between the One and Many is harmonized in the event of language, which in turn positions Gadamer in proximity to the presupposed grounds of receptivity in Cheng’s onto-generative hermeneutics. Lauren Pfister’s contributing article addresses the year 2000 meeting between Cheng and Gadamer in Heidelberg and expands the transhistorical grounds of meaning in Gadamer to matters of theology. Pfister’s summary of the written Chinese record of their conversation indicates that Cheng does not address the role of Christian philosophy and hence, the role of the inner word in Gadamer’s hermeneutics. This is important not only for detecting changes in Cheng’s philosophical development, but also for modifying his hermeneutics along the lines of a living conversation, possibilities explored by Pfister in a sequel to the article submitted to this issue. Nevertheless, by raising the issue of how Gadamer’s turn to language for understanding the meaning of Being extends possibilities in Cheng’s thought, Pfister anticipates the article by Katarina Gajdosova. She returns to the roots of Chinese thought during the Warring States period and broadens the meaning of names in recently excavated texts. Contrary to the conventions about how to understand terms, she appeals to both Heidegger’s ontology and Cheng’s notion of receptivity and creativity to reinterpret naming in relation to cosmology. Along the same lines, insofar as the event of Being is lingual, Jay Goulding captures its emergent structure in an evolving community of scholars and scholarship. He recalls his philosophical journey toward Cheng’s philosophy that begins in conversations with Gadamer at McMaster University in Hamilton, leads to Heidegger and Asian thought, expands into turning points with teachers and colleagues from various backgrounds that by increments contributed to Goulding’s formulation of “Daoist phenomenology.” -/- Although differing traditions guide their inquiries and research, Cheng and Gadamer recall the wisdom of the past to ameliorate the fragmentation in contemporary life. This leads them to re-examine the origins of philosophy; historical roots and thus sources of creative re-interpretations East and West whose affinities are developed in contributions by Hyun Höchsmann and Friederike Assandri. Höchsmann assesses convergences and divergences in the origins of Chinese and Western philosophy (Confucius and Socrates, the Yijing and Pre-Socratics) that culminates in pairing Gadamer’s understanding of paideia in the context of Plato’s political cosmology in the Timaeus with moral and social cultivation in The Western Inscription. She delineates the limits of this comparison which in turn justifies introducing Vattimo’s notion of locality. Assandri’s comparative analysis moves between India and China, Buddhism and Tang Daoism. Based on Gadamer’s argument that writing detaches concepts from their cultural moorings, she defines and applies three levels of understanding in onto-generative hermeneutics to Buddhist terms that were assimilated into the Benji Jing and in so doing clarifies essential dimensions of Daoism. -/- Contributions by Stephen Palmquist and Nicholas Brasovan position Cheng in relation to Kant and Gadamer by way of Aristotle’s ethics respectively. On the one hand, Palmquist plots Cheng’s evolving criticism of Kant’s moral philosophy and draws on crucial dimensions of Gadamer’s hermeneutics to reposition that criticism in a constructive relation to Kant’s emphasis on the philosophical conditions of morality while also indicating how religious dimensions of his thought answer Cheng’s concerns for lived moral action. For Palmquist, Gadamer enables a constructive criticism of Cheng. On the other hand, Brasovan compares Cheng’s Yijing-based account of moral deliberation with Gadamer’s Aristotelian-based ethics and reasons that in contrast to Cheng, Gadamer’s hermeneutical consciousness is disengaged from practical knowledge. For Brasovan, Cheng is a constructive critic of Gadamer. Palmquist and Brasovan’s divergent angles on Gadamer and Cheng map onto a dialectic of contrast and complementarity that constitutes the inner logic of Cheng’s philosophy. In other words, Gadamer and Cheng ought to be read alongside one another for the sake of removing discrepancies and contradictions, which constitutes the organic structure of their thinking. -/- 3 Our Mode of Being in History Is Not Historical The conversations between Cheng and Gadamer in this issue of The Journal of Chinese Philosophy pivot on language, philosophy of history and ethics within a comparative framework of analysis, but also explore the grounds that make the comparisons possible. Those grounds are informed by Chinese cosmology, and function to wrest Gadamer from the shadow of Heideggerian facticity and reposition him within the range of Cheng’s ideas about our place in nature that is embedded in his question about how mind emerges from inorganic matter.8 -/- For Gadamer scholars of Heidegger, human finitude, our ownmost individuating death ensures that hermeneutics is always open to the other as other, always on the way toward understanding the meaning of Being. To arrest the process in a concept of “the Absolute” cannot but represent someone’s point of view, and thereby render hermeneutics indistinguishable from ideology. However, insofar as finitude is defined by them in terms of an onto-theological concept of immorality, finitude is a metaphysical concept consistent with epistemologies and confuse beings with the meaning of Being. As a result, the celebrated political value of hermeneutics to always be on the way toward an understanding of the meaning of Being admits subtle variations on the same worldview that are insufficiently self-critical. -/- Gadamer scholars of Heidegger are right. A transformation in ethos and opening to the meaning of Being depends on awareness of finitude. Yet this awareness does not yield openness to more of the same, i.e., discourse structurally incapable of coming to unity but instead, for both Gadamer and Cheng, openness to a distinctly different ontological dimension of reality. As Sandra Wawrytko and So-Seong Park indicate,9 this ontological dimension is prefigured in the experience of being-as-a-whole or the totality of all possible relations in both Chinese totemic shamanistic rituals,10 and Greek Dionysian festivals.11 Through these religious experiences human ethos and therefore consciousness is expanded and elevated from being centered on one’s ownmost concerns toward an affinity with all sentient beings from insects and plants to animals. The channel for this affinity is an auditory disposition and hence, the emotions, compassion, and feeling response. -/- The capacity for an auditory disposition, or as Gadamer calls it, listening consciousness to respond to the inter-relationality and therefore inherent balance of nature is developed through music, song and dance of the religious rituals and festivals. They facilitate the unity of mind with nature. This use of music, that transforms ordinary consciousness, explains Cheng’s emphasis on the receptivity of feeling response in comprehensive observation, and Gadamer’s emphasis on openness to the other in attunement. However, an auditory disposition characteristic of pre-literate oral cultures that reveals the “All” need not rely on religion. As theorists about the evolution of language have explained,12 modern languages preserve their pre-historical past in music or prosody. That is to say, the song and dance that revealed the totality of inter-related beings to an ethos of comprehensive observation and attunement toward beings in classical civilizations is retained in the back-and-forth movement or rhythm of the dialogue form. Our mode of being in history is a mode of being in nature – through the music of language. -/- While alerting the reader to the limits of a nominalist interpretation, Gadamer expresses the inner law of the nature as follows: “in perishing there is always becoming, and in becoming there is always perishing.”13 Considered in process, opposites generate and blend into each other. This law of nature applies to everything.14 Hence, in a manner comparable to Pfister’s concluding insights, onto-dialogical hermeneutics is not only open to discrete events of otherness but moreover, to the moving structure of reality expressed, as Gajdosova suggests, in the existential moment of naming. Considered as interplay of tension and resolution with a life of its own, the dialectic of a dialogue is self-similar to the way in which an organism grows (by instinct). There is, therefore, a sense in which the art of interpretation extends the human mind into the eternal cycles of nature such that we participate in the articulation of the inner telos/homeostasis toward which all beings strive and importantly for Gadamer scholars of Heidegger, within the material limits of energy to which our embodied minds are self-evidently subject. In mortality there is always immortality. (shrink)

The translation of Rudolf Bode’s Rhythm and its Importance for Education and Rudolf Laban’s ‘Eurhythmy and kakorhythmy in art and education’ aims at unearthing rhythm-related discourses in the Germany of the 1920s. If for most of the English-speaking world the translation of Henri Lefebvre’s Rhythmanalysis: Space, Time and Everyday Life marks the moment in which rhythm descends into the theoretical arena, these texts, seen in their connection with other sources, express, instead, the degree to which rhythm (...) was omnipresent in philosophical, artistic, socio-economical and psychological discourses at the turn of the 20th century. Some commentators, such as Lubkoll, have recently highlighted the centrality of rhythm in Modernity, lamenting a lack of scholarship focusing on this phenomenon. This is arguably due to a lack of access to sources accentuated by the language barrier; if, indeed, the ‘rhythmanalysis’ of the turn of the century is not an exclusively Teutonic phenomenon, it is also true that a copious amount of material on rhythm of this period is written in German and remains untranslated. In this sense, then, this translation aims at contributing to the project of a cultural history of rhythm. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Two Cheers for Blueprints, or, Negative Reasons for Positive UtopianismAntonis Balasopoulos (bio)It is well known that the decline of programmatic or so-called blueprint utopias and utopianism came on the heels of a widespread and concerted attack against them during the first two decades of the Cold War. In the writings of thinkers like Hayek, Popper, Talmon, Kolakowski, and many others, program became synonymous with hubris.1 It was construed as (...) a dangerous effort to regulate the diversity of human subjectivity and the complexity of the social organism, a repressive will-to-order and predictability that tainted utopias by associating them with Totalitarianism. In Popper’s exemplary exposition:The Utopian attempt to realize an ideal state, using a blueprint for society as a whole, is one which demands a strong centralized rule of a few, and which therefore is likely to lead to a dictatorship. [...] [Utopia] claims to plan rationally for the whole of society, although we do not possess anything like the factual knowledge which would be necessary to make good such an ambitious claim.2 [End Page 489]Yet, though this view of how Utopia, to recall Robert C. Elliott, became “a bad word,” is accurate in itself, it also reflects only the negative or destructive side of Cold War anti-utopianism, a trend whose logical inconsistencies and ideological biases have already been ably dissected in the work of Russell Jacoby, Marc Olssen, and Darren Webb, to name but a few.3What one could term the “positive” or “productive” side of anti-utopian denunciations of the dogmatically programmatic character allegedly inherent in utopias went well beyond the exigencies of generating a geopolitical and ideological enemy image. It involved an effort to reconcile western subjects to seismic and highly consequential shifts within postwar, late-capitalist societies themselves. If, as I have argued elsewhere, utopian fictions (and, indeed, nonfictions) before the Cold War period can be read as fictions of organization—of everything from architecture and urban planning, to production, sexuality and biological reproduction, clothing, or diet—it is also the case that in them, “organization” is a response, a reaction to traumatic historical experiences of disorganization, from the decline of the ancient city-state in the case of Platonic utopianism; to the impoverishment and dislocation of rural communities in the era of Thomas More; to the experience of the fracturing of religious community during the religious, civil, and international wars that marked the seventeenth century; to the dramatic impact of early nineteenth-century industrialization on artisanal and agrarian communities, on family cohesion and on the rhythms of the premodern working day.4My argument is, then, that the anti-utopian denunciation of blueprint and program was not simply motivated by the liberal capitalist attack against the planned and highly regulated character of economy and society in the countries of so-called actually existing socialism. It was also motivated by the ideological need to normalize and legitimize the transition, within western capitalist societies themselves, to what Scott Lash and John Urry called “disorganized capitalism.” Lash and Urry’s book, originally published during the decade of the triumphant rise of neoliberalism, in 1987, launches its investigation by tellingly quoting the passage of Marx and Engels’s Communist Manifesto that focuses on the creatively destructive aspects of capitalist social transformation: the bourgeoisie, Lash and Urry observe, is a class “with vested interest in change, crisis and chaos”; the social world over which it presides is one “which swings wildly out of control, menacing and destructive.”5 In their introduction, the authors outline the basic features of the postwar shift from the organized capitalism of the mid-nineteenth and early twentieth centuries to its disarticulated successor formation during the rise of [End Page 490] neoliberal governance. Under the rubric of “disorganization” (which is to say, of a mutation within the western capitalist economic and social order), they include de-industrialization and the decline in the absolute and relative size of the working class in the core capitalist economies; the rise of flexible forms of labor organization in the place of defunct Taylorist principles; the weakening of trade unionist organization; the increasing decoupling of large monopolies from the control and regulation...

To fight against the spread of the coronavirus disease, more than 3 billion people in the world have been confined indoors. Although lockdown is an efficient solution, it has had various psychological consequences that have not yet been fully measured. During the lockdown period in France, we conducted two surveys on two large panels of participants to examine how the lockdown disrupted their relationship with time and what this change in their experiences of time means. Numerous questions were asked (...) about the experience of time but also the nature of life during the lockdown: the emotions felt, boredom, the activities performed, sleep quality, and the daily rhythm. The participants also completed a series of self-reported scales used to assess depression, anxiety, and impulsivity. The results showed that time seemed to pass more slowly during the lockdown compared to before. This feeling of a slowing down of time has little to do with living conditions during the lockdown and individual psychological characteristics. The main predictor of this time experience was boredom and partly mediated by the lack of activity. The feeling of being less happy and the presence of sleep disturbance also explained this specific experience of time albeit to a lesser extent. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Literature as Fable, Fable as ArgumentLester H. HuntIIn an ancient Chinese text we find the following exchange between the Confucian sage Mencius and one of his adversaries:Kao Tzu said, "Human nature is like whirling water. Give it an outlet in the east and it will flow east; give an outlet in the west and it will flow west. Human nature does not show any preference for either good or (...) bad, just as water does not show any preference for either east or west.""It certainly is the case," said Mencius, "that water does not show any preference for either east or west, but does it show the same indifference to high and low? Human nature is good just as water seeks low ground. There is no man who is not good; there is no water that does not flow downwards."1The subject of this colloquy is a familiar one in philosophy as we know it in the West. Its form and style are also vaguely familiar: it is a clashing exchange of theories, in which the speakers do not seem to be speaking merely to express themselves, but in order to persuade others that they are right. Yet at the same time it seems quite alien to us. It would be hard to find anything in it that a Western philosopher since the time of Plato would recognize as an argument. The participants seem to be speaking entirely in illustrative analogies and clever aphorisms, not in arguments at all. The style seems to be literary rather than philosophical. Yet what they are doing does look curiously like arguing. There is a rhythm of statement and counter-statement, in which each speaker seems to be answering the claims of the other.A related, though different, sort of ambiguity, in which the author [End Page 369] really does seem to be both arguing and not arguing, can be found in the following text, traditionally attributed to a Westerner of the sixth century B.C.:Between the North Wind and the Sun, they say, a contest of this sort arose, to wit, which of the two would strip the goatskin from a farmer plodding on his way. The North Wind first began to blow as he does when he blows from Thrace, thinking by sheer force to rob the wearer of his cloak. And yet no more on that account did he, the man, relax his hold; instead he shivered, drew the borders of his garment tight about him every way, and rested with his back against a spur of rock. Then the Sun peeped forth, welcome at first, bringing the man relief from the cold, raw wind. Next, changing, he turned the heat on more, and suddenly the farmer felt too hot and of his own accord threw off the cloak, and so was stripped.Thus was the North Wind beaten in the contest. And the story means: "Cultivate gentleness, my son; you will get results oftener by persuasion than by the use of force."2Here Aesop, to use the traditional name for the author of this ancient fable, is plainly doing something "literary": he is telling a story. But narration in the Aesopian mode is never simply telling a story, and in this case what is present in addition to the story seems to have something logical about it. Personally, I read this fable with a certain sense, however faint, that I am being enlightened by it. That of course is Aesop's aim. He is not merely expressing his opinion, but in some way showing us the truth of it. This is the sort of thing that, in philosophy, is done through argument. However, as in the text from the Mencius, it seems there may be no argument here.Clearly, we are dealing with forms of persuasion that are common at certain times in the development of a culture: namely, those periods when the philosophical muse is a mere suckling babe. We are looking, one might think, at a level of development so rudimentary that the distinction between argument as we think of it today and other forms of persuasion has not been made... (shrink)

The phonetic evolution of the Greek language which, towards the end of the Hellenistic period, substituted for the quantitative rhythm, based on the opposition of duration of the syllables, a rhythm based on the distance between stressed syllables, allowed the emergence of new poetic processes which followed after the traditional metrics: the equality of number of accents between several cola and the echoes between stress-related clausulae. The analysis of some of Alciphro’s bucolic letters from this point of (...) view reveals that they are sorts of poèmes en prose organized in isotonic stanzas, with isotony of cola and recurring clausulae in close echoes. This discovery reveals the really artistic character of these letters. It also supplies a criterion of choice between variants or conjectures when the text is corrupted. (shrink)

The core dimensions of cognitive fitness, such as attention and cognitive control, are emerging through a transdisciplinary expert consensus on what has been termed the Cognitive Fitness Framework. These dimensions represent key drivers of cognitive performance under pressure across many occupations, from first responders to sport, performing arts and the military. The constructs forming the building blocks of CF2 come from the RDoC framework, an initiative of the US National Institute of Mental Health aimed at identifying the cognitive processes underlying (...) normal and abnormal behavior. Similar to physical conditioning, cognitive fitness can be improved with deliberate practice. This paper reports the development of a prototype cognitive fitness training program for competitive athletes and the protocol for its evaluation. The program is focused on primary cognitive capacities and subtending skills for adjusting training rhythms and enhancing readiness for competition. The project is driven by the Australian Psychological Society’s College of Sport & Exercise Psychology and includes the development of a Cognitive Gym program for a smartphone app-enhanced implementation. Its key building blocks are training protocols connected by a periodized training plan. A website with background supporting resources has also been developed as part of the project. National-level training squads will participate in a three-week pilot evaluation protocol, assessing the program’s efficacy and usability through gamified cognitive assessment of participants’ training gains and coaching staff evaluations, respectively. Both near and far transfer of training effects will be examined. (shrink)

In many fields of biology, both the phenomena to be explained and the mechanisms proposed to explain them are commonly presented in diagrams. Our interest is in how scientists construct such diagrams. Researchers begin with evidence, typically developed experimentally and presented in data graphs. To arrive at a robust diagram of the phenomenon or the mechanism, they must integrate a variety of data to construct a single, coherent representation. This process often begins as the researchers create a first sketch, and (...) it continues over an extended period as they revise the sketch until they arrive at a diagram they find acceptable. We illustrate this process by examining the sketches developed in the course of two research projects directed at understanding the generation of circadian rhythms in cyanobacteria. One identified a new aspect of the phenomenon itself, whereas the other aimed to develop a new mechanistic account. In both cases, the research resulted in a paper in which the conclusion was presented in a diagram that the authors deemed adequate to convey it. These diagrams violate some of the normative “cognitive design principles” advanced by cognitive scientists as constraints on successful visual communication. We suggest that scientists’ sketching is instead governed by norms of success that are broadly explanatory: conveying the phenomenon or mechanism. (shrink)
