In this paper, we introduce and defend the recurrent model for understanding bodily spatial phenomenology. While Longo, Azañón and Haggard (2010) propose a bottom-up model, Bermúdez (2017) emphasizes the top-down aspect of the information processing loop. We argue that both are only half of the story. Section 1 intro- duces what the issues are. Section 2 starts by explaining why the top- down, descending direction is necessary with the illustration from the ‘body-based tactile rescaling’ paradigm (de Vignemont, Ehrsson and Haggard, (...) 2005). It then argues that the bottom-up, ascending direction is also necessary, and substantiates this view with recent research on skin space and tactile field (Haggard et al., 2017). Section 3 discusses the model’s application to body ownership and bodily self-representation. Implications also extend to topics such as sense modality individuation (Macpherson, 2011), the constancy- based view of perception (Burge, 2010), and the perception/cognition divide (Firestone and Scholl, 2016).

This article addresses the semiotic problem of how meaning is agentially grounded: how actual meaning is possible and is justifiably supported by agents’ capabilities and purposes. This article is particularly focused on human agential grounding; however, to a great degree, insights presented here can be extended to other living beings. Specifically, agential meaning is examined here inside the framework of agentive semiotics and embodied, situated and enactive cognition theories, in line with the mind-life continuity general thesis. To offer clarity and (...) methodological precision about agential grounding, three explanation categories are proposed: phylogenetic recurrence, the evolutionary basis for corporal/embodied grounding; ontogenetic recurrence, the developmental basis for individual meaning grounding; and collective recurrence, the basis for meaning recognized, attributed and assigned inside social contexts. These recurrences are conceived as three types of general processes that constantly enclose possibilities for purpose and meaning emergence in humans. As a result of these types of recurrences, two categories of human agendas or purposes are also proposed: individual and collective. Finally, remarks about how these categories can be useful for semiotic analysis and further research are suggested. (shrink)

In True Detective, the description of time as a "flat circle" is one of the most mysterious aspects of the story. The idea of the flat circle ultimately helps Rust to overcome his bleak interpretation of reality, although for a long time it anchors him in his dreary worldview. A philosophical pessimist is likely to view knowledge and meaning as inherently flawed. Rust tells Marty all about his philosophical pessimism in the first episode of season one. A metaphysical claim tries (...) to describe the true nature of reality. Friedrich Nietzsche calls his theory "eternal recurrence", however differ in name aside, there are numerous similarities between his theory and Rust's. The flat circle is really a thought experiment that Rust remains trapped within insofar as he remains a philosophical pessimist, at least up to the point of his near‐death experience, where he "sees the light".

I discuss classical and quantum recurrence theorems in a unified manner, treating both as generalisations of the fact that a system with a finite state space only has so many places to go. Along the way I prove versions of the recurrence theorem applicable to dynamics on linear and metric spaces, and make some comments about applications of the classical recurrence theorem in the foundations of statistical mechanics.

(Version 2.4) I have argued elsewhere for ascribing an error theory about all normative and evaluative judgements to Nietzsche. Such a nihilism brings with it a puzzle: how could we—or at least the select few of us being addressed by Nietzsche—continue in the face of this nihilism? This is a philosophical puzzle and so, defeasibly, an interpretive puzzle. If there is no theory it would make sense for Nietzsche to have about how the select few could go on, then this (...) is some evidence against the proposed interpretation of him as a nihilist. I defended the interpretation by arguing that Nietzsche’s declarations about creating values point to a practice of generating honest evaluative illusions. Such honest evaluative illusions are tricky things, though, and, precisely because they are honest, one might worry that they lack the motivational power of genuine evaluative belief. Can they truly play the role that evaluative beliefs play in our psychological economies? I suspect that Nietzsche does not want the honest illusions to play exactly the role that evaluative beliefs played. The cheerfulness, the playfulness, the lightness that Nietzsche hopes for are, I have suggested, a function of the shift from belief to pretence, from illusion to honest illusion. The question, nonetheless, is whether the resulting picture is too light. Can I go through life merely acting, as a critic might put it? My suggestion in this essay will be that the thought of eternal recurrence is meant to add weight to the lightness of acting—“acting”, obviously, in both the here relevant senses of the word.

This paper proposes several recurrent neural network-based models for recognizing requisite and effectuation parts in Legal Texts. Firstly, we propose a modification of BiLSTM-CRF model that allows the use of external features to improve the performance of deep learning models in case large annotated corpora are not available. However, this model can only recognize RE parts which are not overlapped. Secondly, we propose two approaches for recognizing overlapping RE parts including the cascading approach which uses the sequence of BiLSTM-CRF models (...) and the unified model approach with the multilayer BiLSTM-CRF model and the multilayer BiLSTM-MLP-CRF model. Experimental results on two Japan law RRE datasets demonstrated advantages of our proposed models. For the Japanese National Pension Law dataset, our approaches obtained an \ score of 93.27% and exhibited a significant improvement compared to previous approaches. For the Japan Civil Code RRE dataset which is written in English, our approaches produced an \ score of 78.24% in recognizing RE parts that exhibited a significant improvement over strong baselines. In addition, using external features and in-domain pre-trained word embeddings also improved the performance of RRE systems. (shrink)

This article shows that Nietzsche’s published presentations endorse the cosmological truth of eternal recurrence and that they indicate how belief in this truth can be supported with direct mnemonic evidence as well as a priori scientific proof. It also introduces a refutation of any attempt to construe Nietzsche’s doctrine as a thought experiment that would help to test or promote the affirmation of nonrecurring life.

There is increasing interest in how the pupil dynamics of the eye reflect underlying cognitive processes and brain states. Problematic, however, is that pupil changes can be due to non-cognitive factors, for example luminance changes in the environment, accommodation and movement. In this paper we consider how by modeling the response of the pupil in real-world environments we can capture the non-cognitive related changes and remove these to extract a residual signal which is a better index of cognition and performance. (...) Specifically, we utilize sequence measures such as fixation position, duration, saccades, and blink-related information as inputs to a deep recurrent neural network (RNN) model for predicting subsequent pupil diameter. We build and evaluate the model for a task where subjects are watching educational videos and subsequently asked questions based on the content. Compared to commonly-used models for this task, the RNN had the lowest errors rates in predicting subsequent pupil dilation given sequence data. Most importantly was how the model output related to subjects' cognitive performance as assessed by a post-viewing test. Consistent with our hypothesis that the model captures non-cognitive pupil dynamics, we found (1) the model's root-mean square error was less for lower performing subjects than for those having better performance on the post-viewing test, (2) the residuals of the RNN (LSTM) model had the highest correlation with subject post-viewing test scores and (3) the residuals had the highest discriminability (assessed via area under the ROC curve, AUC) for classifying high and low test performers, compared to the true pupil size or the RNN model predictions. This suggests that deep learning sequence models may be good for separating components of pupil responses that are linked to luminance and accommodation from those that are linked to cognition and arousal.

When multiple individuals interact in a conversation or as part of a large crowd, emergent structures and dynamics arise that are behavioral properties of the interacting group rather than of any individual member of that group. Recent work using traditional signal processing techniques and machine learning has demonstrated that global acoustic data recorded from a crowd at a basketball game can be used to classify emergent crowd behavior in terms of the crowd's purported emotional state. We propose that the description (...) of crowd behavior from such global acoustic data could benefit from nonlinear analysis methods derived from dynamical systems theory. Such methods have been used in recent research applying nonlinear methods to audio data extracted from music and group musical interactions. In this work, we used nonlinear analyses to extract features that are relevant to the behavioral interactions that underlie acoustic signals produced by a crowd attending a sporting event. We propose that recurrence dynamics measured from these audio signals via recurrence quantification analysis (RQA) reflect information about the behavioral dynamics of the crowd itself. We analyze these dynamics from acoustic signals recorded from crowds attending basketball games, and that were manually labeled according to the crowds' emotional state across six categories: angry noise, applause, cheer, distraction noise, positive chant, and negative chant. We show that RQA measures are useful to differentiate the emergent acoustic behavioral dynamics between these categories, and can provide insight into the recurrence patterns that underlie crowd interactions.

Recurrent neural network has been widely applied to many sequential tagging tasks such as natural language process and time series analysis, and it has been proved that RNN works well in those areas. In this paper, we propose using RNN with long short-term memory units for server load and performance prediction. Classical methods for performance prediction focus on building relation between performance and time domain, which makes a lot of unrealistic hypotheses. Our model is built based on events, which is (...) the root cause of server performance. We predict the performance of the servers using RNN-LSTM by analyzing the log of servers in data center which contains user’s access sequence. Previous work for workload prediction could not generate detailed simulated workload, which is useful in testing the working condition of servers. Our method provides a new way to reproduce user request sequence to solve this problem by using RNN-LSTM. Experiment result shows that our models get a good performance in generating load and predicting performance on the data set which has been logged in online service. We did experiments with nginx web server and mysql database server, and our methods can been easily applied to other servers in data center. (shrink)

A new method for evaluating aircraft engine monitoring data is proposed. Commonly, prognostics and health management systems use knowledge of the degradation processes of certain engine components together with professional expert opinion to predict the Remaining Useful Life (RUL). New data-driven approaches have emerged to provide accurate diagnostics without relying on such costly processes. However, most of them lack an explanatory component to understand model learning and/or the nature of the data. A solution based on a novel recurrent version of (...) a VAE is proposed in this paper to overcome this gap. The latent space learned by the model, trained with data from sensors placed in different parts of these engines, is exploited to build a self-explanatory map that can visually evaluate the rate of deterioration of the engines. Besides, a simple regressor model is built on top of the learned features of the encoder in order to numerically predict the RUL. As a result, remarkable prognostic accuracy is achieved, outperforming most of the novel and state-of-the-art approaches on the available modular aero-propulsion system simulation data (C-MAPSS dataset) from NASA. In addition, a practical real-world application is included for Turbofan engine data. This study shows that the proposed prognostic and explainable framework presents a promising new approach.

In (Weaver 2021), I showed that Boltzmann’s H-theorem does not face a significant threat from the reversibility paradox. I argue that my defense of the H-theorem against that paradox can be used yet again for the purposes of resolving the recurrence paradox without having to endorse heavy-duty statistical assumptions outside of the hypothesis of molecular chaos. As in (Weaver 2021), lessons from the history and foundations of physics reveal precisely how such resolution is achieved.

_ Source: _Volume 9, Issue 2, pp 196 - 219 In his 1978 On Human Nature, Edward Wilson defined the evolutionary epic as the scientific story of all life, a linear narrative beginning with the big bang and ending with the story of human history. Since that time several popular science writers have attempted to write that story of life producing such titles as The Universe Story and The Epic of Evolution. Historians have also gotten into the act under the (...) guise of “Big History,” which has resulted in a series of monographs and is taught at several universities and high schools throughout the world. While the evolutionary epic is often presented as a novel way of bringing the historical insights of modern science into a narrative form that transcends the humanities–natural science divide, the genre itself originates in the nineteenth century, just as new geological and cosmic timescales were being established and new sciences such as biology and anthropology were being formalized. Several German Naturphilosophen and Victorian naturalists imagined the history of life as one, as a “Cosmos,” and produced evolutionary epics that bare significant similarities with their more modern counterparts. By considering the various recurrences of the evolutionary epic, from its origins in early German Romanticism and Victorian naturalism to the degeneration narratives of the fin de siècle and on to the Wilsonian and Big History versions of the late twentieth century and beyond, this essay seeks to map out a shared intellectual genealogy while examining the genre’s conceptual commonalities. What is perhaps most compelling about the history of the genre is the striking persistence of non-Darwinian forms of evolution that are utilized to situate the emergence of humanity in these epic narratives of life.

The question has been raised whether Nietzsche intends eternal recurrence to be like a categorical imperative. The obvious objection to understanding eternal recurrence as like a categorical imperative is that for a categorical imperative to make any sense, for moral obligation to make any sense, it must be possible for individuals to change themselves. And Nietzsche denies that individuals can change themselves. Magnus thinks the determinism “implicit in the doctine of the eternal recurrence of the same renders (...) any imperative impotent…. How can one will what must happen in any case?” At the other end of the spectrum, those who do hold that eternal recurrence is like a categorical imperative, for their part, tend to ignore or deny the determinism involved in eternal recurrence. This article explores the extent to which it can be claimed that eternal recurrence is like a categorical imperative without downplaying Nietzsche's dterminism. (shrink)

The article is primarily a study of Nietzsche’s unpublished fragments from the period spring-autumn 1881, in which Nietzsche first developed his thought of the “eternal recurrence of the same.” In the article, I attempt to accomplish two goals: the first goal is to explain Nietzsche’s theses on the eternal recurrence, which at that time were still remarkably clear and coherent. And the second goal is to try to find in these same theses an explanation for their future silence. (...) In other words, the article examines the relationship between Nietzsche’s theses that he developed in 1881 and his book _Thus spoke Zarathustra_, which, in Nietzsche’s own words, relies on these theses as their “grounding thought,” but nevertheless never fully reveals them. Both lines of inquiry lead to the conclusion that the core of Nietzsche’s introduction of the idea of eternal recurrence is his concept of _Einverleibung_ or embodiment. Indeed, the analysis shows that Nietzsche’s main concern with the thought of eternal recurrence was not to set forth its clear articulation within consciousness, but rather to construct it in such a way that it could become an unconscious instinct capable of gradually displacing the “embodied mistakes” that dominate our thinking from within itself.

The relationship between attention and consciousness is one that is crucial for understanding perception and different types of conscious experience, and we commend this analysis of the topic by Pitts, Lutsyshyna, and Hillyard (2018). We have also examined this relationship closely (e.g., Montemayor & Haladjian, 2015) and would like to point out a few potential contradictions in the Pitts et al. paper that require clarification, particularly in the attempt to reconcile aspects of recurrent processing theory (RPT) with global neuronal workspace (...) theory (GNWT). This commentary addresses these points and introduces other considerations important for this topic. (shrink)

The article differentiates between the manifestation of recurrence qua consciousness and an underlying recurrence elaborated by Levinas in subjectivity beyond being. The movement of recurrence is traced in its relation to creation. Ethics is the language in which the selfless can be expressed, where value obtains in lieu of being. The philosophical problem to which recurrence is a response is posited as ipseity versus identiy. The self imposed obstacles to extracting a moral doctrine from the levinasian (...) corpus are discussed, followed by suggestions on the difference a levinasian view might make in our understanding and undertaking of every day life.

Neste ensaio, argumento que qualquer um que adotasse um falsificacionismo do tipo que tenho atribuído a Nietzsche se sentiria atraído pela doutrina do eterno retorno. Para Nietzsche, pensar o 'vir a ser' revelado por meio dos sentidos significa falsificá-lo por meio do 'ser'. Mas o eterno retorno oferece a possibilidade de pensar o 'vir a ser' sem falsificação. Em seguida, argumento que qualquer um que mantenha o falsificacionismo de Nietzsche veria na ação humana um conflito entre o 'ser' e o (...) 'vir a ser', de modo semelhante ao que ocorre no juízo empírico. À luz desse conflito apenas o eterno retorno ofereceria a possibilidade de afirmar a vida de modo verdadeiro. Para concluir, discuto de que maneira tal leitura do eterno retorno resolve uma série de enigmas que têm atormentado os intérpretes. In this essay, I argue that someone who adopted a falsificationism of the sort that I have attributed to Nietzsche would be attracted to the doctrine of eternal recurrence. For Nietzsche, to think the becoming revealed through the senses means falsifying it through being. But the eternal recurrence offers the possibility of thinking becoming without falsification. I then argue that someone who held Nietzsche's falsificationism would see in human agency a conflict between being and becoming similar to that in empirical judgment. In the light of this conflict only the eternal recurrence would offer the possibility of truly affirming life. I end by discussing how this reading of the eternal recurrence solves a number of puzzles that have bedeviled interpreters. (shrink)

Timely detection and efficient recognition of fault are challenging for the bogie of high-speed train, owing to the fact that different types of fault signals have similar characteristics in the same frequency range. Notice that convolutional neural networks are powerful in extracting high-level local features and that recurrent neural networks are capable of learning long-term context dependencies in vibration signals. In this paper, by combining CNN and RNN, a so-called convolutional recurrent neural network is proposed to diagnose various faults of (...) the HST bogie, where the capabilities of CNN and RNN are inherited simultaneously. Within the novel architecture, the proposed CRNN first filters out the features from the original data through convolutional layers. Then, four recurrent layers with simple recurrent cell are used to model the context information in the extracted features. By comparing the performance of the presented CRNN with CNN, RNN, and ensemble learning, experimental results show that CRNN achieves not only the best performance with accuracy of 97.8% but also the least time spent in training model.

The doctrine of eternal recurrence, the claim that everytning that occurs does so not only once but infinitely many times, figures in the writings of Nietzsche in several forms, and it can be understood in different ways. Here I shall show that one of these approaches allows us to see the doctrine as a philosophical theory about the nature of reality: that is, as an ontological doctrine. The interpretation is worth exploring because it allows us not only to see (...) what Nietzsche's arguments really are, but also to bring to light problems and objections that go unnoticed in most accounts of the idea.

Though many would prefer to have nothing to do with teleological explanations, it is evident that the writings of biologists and social scientists abound with them, and it is worth paying attention to the conditions under which they may be made responsibly.

In the final part of (...) the paper it is shown that satisfying this condition provides a basis for formulating general laws of the more orthodox kind. (shrink)

The belief that the past consists of discrete (...) cultural episodes does not exclude the possibility that these episodes have a common structure. The conception explored in this chapter is sometimes referred to as historical cycles. (shrink)

It has been shown that Recurrent Artificial Neural Networks automatically acquire some grammatical knowledge in the course of performing linguistic prediction tasks. The extent to which such networks can actually learn grammar is still an object of investigation. However, being mostly data-driven, they provide a natural testbed for usage-based theories of language acquisition. This mini-review gives an overview of the state of the field, focusing on the influence of the theoretical framework in the interpretation of results.

Markov blankets – statistical independences between system and environment – have become popular to describe the boundaries of living systems under Bayesian views of cognition. The intuition behind Markov blankets originates from considering acyclic, atemporal networks. In contrast, living systems display recurrent, nonequilibrium interactions that generate pervasive couplings between system and environment, making Markov blankets highly unusual and restricted to particular cases.

It is crucial, first of all, to stress the importance Churchland attaches to the idea that the neural networks whose assemblages he holds to be “engines of reason” must be recurrent. Non-recurrent networks, of the sort best known among philosophers, simply discover patterns in input data presented to them as sets of features. The learning capacities of such networks, extensively discussed since the publication of Rumelhart and McClelland et al., are indeed impressive; and Churchland describes them clearly and gracefully as (...) preparation for introducing recurrent networks. Now, the importance of recurrence as a feature of the networks Churchland hypothesizes as forming the basis of cognitive activity is well motivated. A cognitive system that was an assembly of non-recurrent networks would be, in essence, a stimulus-response machine of the sort that early behaviourists took themselves to be studying when they examined the mind/brain. Such a system could learn to find novel patterns in data. However, it is empirically evident that human— and some non-human—cognitive capacities go well beyond this. People dream, imagine scenarios that never existed, reconceptualize their perceptions, and theorize. All these activities seem to require not merely inferring patterns from data, but reconceiving the nature of the data itself in light of the inferential structures built through learning. For this to be possible, the data cannot be “clamped,” as they are in the case of non-recurrent networks. Hence the importance of recurrence. A recurrent network can be defined as one which takes some or all of its own output and then treats that output as a source of input. This allows for the recognition of meta-patterns. Furthermore, if some such networks are feeding their output as input to other networks with which they are linked, the possibility of reasoning and conceptualizing by analogy arises; and this ability, as Churchland argues, seems to be an essential aspect of genuine creativity in science, art, and the continuously ongoing re-design of the social order. The actual existence of simulated recurrent networks, and the capacities they demonstrate, constitute an impressive possibility argument that a system with enormous cognitive plasticity and behavioural flexibility could be built out of parallel distributed processing networks, so long as at least many of these networks were recurrent. The importance of this possibility argument should not be under-emphasized, but it of course invites an obvious question: how good are our grounds for supposing that the possibility in question is actually realized in the biological domain?

This essay examines the recurrence of New Age typologies in different ages and different cultures. The archetype is defined as the revolutionary idealist who is intellectual, declassé, an experimenter and a seeker after truth. The essay then proceeds to compare and contrast key intellectual and spiritual figures to establish the extent to which they conform to the archetype: Percy Shelley and Otto Gross, Mahatma Gandhi and St. Francis of Assisi. It concludes with an examination of the career and ideas (...) of John Middleton Murry and argues the case for him to be seen as a New Age archetype — the New Age man of letters. (shrink)

I critically examine Nietzsche’s argument in The Will to Power that all the detailed events of the world are repeating infinite times (on account of the merely finite possible arrangements of forces that constitute the world and the inevitability with which any arrangement of force must bring about its successors). Nietzsche celebrated this recurrence because of the power of belief in it to bring about a revaluation of values focused wholly on the value of one’s endlessly repeating life. Belief (...) in recurrence would bring joy to those who had achieved excellence in this life and crush those who had not. I point out, however, that this significance of recurrence must be spoiled by the consideration that within each of the long cycles of recurrence there would have to be, as well, countless variations of this life. And I consider the issue of personal identity within such recurrences. Is it the same person or merely resembling but distinct persons in the recurrences or the variations? If it is the same person in precise recurrences, should the subjectively identical experience be thought of as really additional for that person? (shrink)

Objective:Fear of Cancer Recurrence (FCR), Health Anxiety (HA), worry, and uncertainty in illness are psychological concerns commonly faced by cancer patients. In survivorship research, these similar, yet different constructs are frequently used interchangeably and multiple instruments are used in to measure them. The lack of clear and consistent conceptualization and measurement can lead to diverse or contradictory interpretations. The purpose of this scoping review was to review, compare, and analyze the current conceptualization and measurements used for FCR, HA, worry, (...) and uncertainty in the breast cancer survivorship literature to improve research and practice.Inclusion Criteria:We considered quantitative, qualitative, and mixed methods studies of breast cancer survivors that examined FCR, HA, worry, or uncertainty in illness as a main topic and included a definition or assessment of the constructs.Methods and Analysis:The six-staged framework was used to guide the scoping review process. Searches of PubMed, CINAHL, and PsycINFO databases were conducted. The principle-based qualitative analysis and simultaneous content analysis procedures were employed to synthesize and map the findings.Findings:After duplicate removal, the search revealed 3,299 articles, of which 82 studies met the inclusion criteria. Several critical attributes overlapped the four constructs, for example, all were triggered by internal somatic and external cues. However, several unique attributes were found (e.g., a sense of loss of security in the body is observed only among survivors experiencing FCR). Overall, findings showed that FCR and uncertainty in illness are more likely to be triggered by cancer-specific factors, while worry and HA have more trait-like in terms of characteristics, theoretical features, and correlates. We found that the measures used to assess each construct were on par with their intended constructs. Eighteen approaches were used to measure FCR, 15 for HA, 8 for worry, and 4 for uncertainty.Conclusion:While consensus on the conceptualization and measurement of the four constructs has not yet been reached, this scoping review identifies key similarities and differences to aid in their selection and measurement. Considering the observed overlap between the four studied constructs, further research delineating the unique attributes for each construct is warranted. (shrink)

Paul Churchland does not open his latest book,The Engine of Reason, the Seat of the Soul, modestly. He begins by announcing, “This book is about you. And me … More broadly still, it is about every creature that ever swam, or walked, or flew over the face of the Earth” (p. 3). A few sentences later, he says, “Fortunately, recent research into neural networks … has produced the beginnings of a real understanding of how the biological brain works—a real understanding, (...) that is, of howyouwork, and everyone else like you” (p. 3). The implicit identification here of “me and you and everyone” with “the biological brain” might lead an uncharitable reader to view Churchland's book as “Eliminativism for the non-specialist,” that is, as an attempt to popularize the view of the mindbody problem with which, among his professional peers, Churchland has long been identified. However, I think that such a readingwouldbe uncharitable. He is, of course, frequently sceptical about the utility of folk psychology, but in this book he is much less concerned to disparage folk psychology as a failedtheory(by contrast with, for example, the arguments in Churchland 1979) than to urge the more modest view that the more we understand the brain, the better we shall be at helping those whose brains are damaged in ways that interfere seriously with the fulfilment of their lives. Hence, I am inclined to take him at his word when he says in the Preface that “The book is motivated first of all by sheer excitement over the new picture that is now emerging … [and] … also by the idea that this is information that the public needs to know” (p. xi). What excites Churchland so, at least overtly, is not the negative thesis he has defended elsewhere that folk-psychological terms fail to refer; his enthusiasm is mainly reserved for the positive thesis that minds are, essentially, interacting assemblies of recurrent neural networks. It is therefore this positive thesis, and Churchland's defence of it, that I will assess in the following discussion. (shrink)

The paper analyzes dynamic epistemic logic from a topological perspective. The main contribution consists of a framework in which dynamic epistemic logic satisfies the requirements for being a topological dynamical system thus interfacing discrete dynamic logics with continuous mappings of dynamical systems. The setting is based on a notion of logical convergence, demonstratively equivalent with convergence in Stone topology. Presented is a flexible, parametrized family of metrics inducing the latter, used as an analytical aid. We show maps induced by action (...) model transformations continuous with respect to the Stone topology and present results on the recurrent behavior of said maps. (shrink)

The cyclical theory f time, which is better known under the name of the 'theory of eternal recurrence,' is usually associated with certain ancient thinkers--in particular, Pythagoreans and Stoics. The most famous among those who have tried to revive the theory in the modern era is unquestionably Friedrich Nietzsche. It is less well known that the theory was defended also by C.S. Peirce and, as late as 1927, by the French historian of science, Abel Rey. The contemporary discussion of (...) the problem of the direction of time has a direct bearing on the problem of eternal recurrence. The primary purpose of this paper is to evaluate critically the theory itself and then to show how this critical analysis can be applied to Peirce's own version of this theory. (shrink)

For an arbitrary finite algebra $\g A = (A, f, 0, 1)$ one defines a double sequence $a(i,j)$ by $a(i,0)\!=\!a(0,j)\! =\! 1$ and $a(i,j) \!= \!f( a(i, j-1) , a(i-1,j) )$.The problem if such recurrent double sequences are ultimately zero is undecidable, even if we restrict it to the class of commutative finite algebras.

Nietzsche believed in the horror of existence—in a world filled with meaningless suffering. He also believed in eternal recurrence—that our lives will repeat infinitely and that in each life every detail will be exactly the same. Furthermore, it was not enough that eternal recurrence simply be accepted—Nietzsche demanded that it be loved. Thus the philosopher who introduces eternal recurrence is the very same philosopher who also believes in the horror of existence—a paradox that is completely overlooked by (...) commentators (who thus fail to adequately understand Nietzsche). All of this demands careful explanation. (shrink)

I am grateful to Nathan Salmon [in Salmon (2012)] for being willing to spill so much ink over my monograph on semantic relationism (2007), even if what he has to say is not altogether complimentary.

Approaching the idea from three viewpoints, The author contends that eternal recurrence is a central and unifying theme in nietzsche's thought. She first considers its scientific basis, Arguing for a reinterpretation of the doctrine because nietzsche did not subscribe to the classical atomism of his time. She then considers the idea in its metaphysical perspective: it represents a repudiation of platonism and an affirmation of life. Finally, Urging the unity of the metaphysical and the ethical in nietzsche's philosophy, The (...) author interprets eternal recurrence as an idea created by life itself to serve life by strengthening the will to power.

Nietzsche's concept of eternal recurrence has traditionally been understood according to two primary interpretations: the cosmological and hypothetical. Those who opt for the cosmological suggest that recurrence is a factual, almost scientific, account of the circularity of both time and events. In opposition, Magnus, and those who accept the hypothetical position, offer circularity as an attitudinal approach to existence. This article argues that both understandings are suspect when confronted with the remainder of Nietzschean thought. As an alternative I (...) will suggest that recurrence can only be grasped in the remainder can only be grasped in the recognition of the Moment' as the what' of the return. (shrink)

We show that recurrence conditions do not yield invariant Borel probability measures in the descriptive set-theoretic milieu, in the strong sense that if a Borel action of a locally compact Polish group on a standard Borel space satisfies such a condition but does not have an orbit supporting an invariant Borel probability measure, then there is an invariant Borel set on which the action satisfies the condition but does not have an invariant Borel probability measure.

Standard compositionality is the doctrine that the semantic content of a compound expression is a function of the semantic contents of the contentful component expressions. In 1954 Hilary Putnam proposed that standard compositionality be replaced by a stricter version according to which even sentences that are synonymously isomorphic (in the sense of Alonzo Church) are not strictly synonymous unless they have the same logical form. On Putnam’s proposal, the semantic content of a compound expression is a function of: (i) the (...) contentful component expressions; and (ii) the expression’s logical form. Kit Fine recently expanded and modified Putnam’s idea into a sweeping theory in philosophy of language and philosophy of mind. The present paper is a detailed critique of Fine’s “semantic relationism.” Fine’s notion of coordination is explained in terms of the familiar pragmatic phenomenon of recognition. A serious error in Fine’s formal disproof of standard Millianism is exposed. It is demonstrated furthermore that Church’s original criticism of Putnam’s proposal can be extended to Fine’s semantic relationism. Finally, it is also demonstrated that the positive position Fine proffers to supplant standard Millianism is in fact exactly equivalent to standard Millianism, so that Fine’s overall position not only does not displace standard Millianism but is in fact inconsistent.

The essay introduces an interpretation of Nietzsche's Eternal-Recurrence-Thought distinct from traditional 'cosmological' as well as 'ethical' interpretations. The interpretation suggests that eternal recurrence is a conceptualization of intellectual and volitional processes. External recurrence is understood as a concept articulating peculiarities about mental processes related to knowledge and pleasure.Der Aufsatz stellt ein Interpretation von Nietzsches Gedanken der Ewigen Wiederkunft vor, die weder 'kosmologisch' noch 'ethisch' sein möchte. Diese Interpretation hält die Ewige Wiederkunft für eine Konzeptualisierung von Verstandes- und (...) Willensakten. Der Begriff der Ewigen Wiederkunft wäre somit entworfen, um Besonderheiten der Prozesse des Scelenlebens zu artikuliern, die mit Erkenntnis und Lust zu tun haben. (shrink)

We report the identification of a recurrent, 520-kb 16p12.1 microdeletion associated with childhood developmental delay. The microdeletion was detected in 20 of 11,873 cases compared with 2 of 8,540 controls and replicated in a second series of 22 of 9,254 cases compared with 6 of 6,299 controls. Most deletions were inherited, with carrier parents likely to manifest neuropsychiatric phenotypes compared to non-carrier parents. Probands were more likely to carry an additional large copy-number variant when compared to matched controls. The clinical (...) features of individuals with two mutations were distinct from and/or more severe than those of individuals carrying only the co-occurring mutation. Our data support a two-hit model in which the 16p12.1 microdeletion both predisposes to neuropsychiatric phenotypes as a single event and exacerbates neurodevelopmental phenotypes in association with other large deletions or duplications. Analysis of other microdeletions with variable expressivity indicates that this two-hit model might be more generally applicable to neuropsychiatric disease. © 2010 Nature America, Inc.
