System analyses deal with interrelationships between different variables that keep the system in balance. In many analysis of complex thinking, a system is viewed as a complex unit in which the ‘whole’ is not reduced to the ‘sum’ of its parts; the system becomes an ambiguous item because it consists of several entities that interact with unforeseen results or, in other words, it is situated at a transdisciplinary level, it is impossible for an area to have a complete reading of (...) its complexity. It was also mentioned that the concept of the open system best describes complexity by stating that ‘the laws of the organization are not equilibrium, but an imbalance that is restored or compensated for by stabilized dynamics’. This idea originated from the field of thermodynamics and the second law, in which the imbalance that it maintains allows the system for an apparent balance. This fragile steady state has something of a paradox, since the structures remain the same, but their constituents are changeable. The concept of open system undoes the door to a theory of evolution that can only derive from the interactions between a system and its ecosystem. Within this systemic approach, the focus of the analysis takes into account the ambiguity, multidisciplinary and complexity associated with system adjustment, i.e. it is intended to qualify an employee job based on their experience and knowledge as a measure of their impact on the organization performance.

Sexting has been defined as sending, receiving, or forwarding sexually explicit messages, images, or photos to others through digital platforms, and can assume more consensual or more abusive and violent forms. This study aims to explore the prevalence of abusive sexting in Portuguese adolescents and the psychological characteristics of sexting abusers in terms of emotional and behavioral problems, potential markers of psychopathy, childhood trauma and maltreatment, and different forms of aggression. A cross-sectional study was conducted with 4,281 participants, aged 12–20 (...) years, of whom 204 engaged in abusive sexting behaviors and 182 self-identified as being a non-consensual sexting victim. Abusive sexting was more common among boys and middle adolescents, and abusive sexting victims were more likely to be children of single-parent families. Engaging in abusive sexting and being a victim of abusive sexting were also related to behavioral and emotional problems, callousness, experiences of neglect and abuse in childhood, and various forms of aggression. Implications for future research and intervention are discussed. (shrink)

In the course of recent investigations on artificial intelligence (AI) and its scope in different societal domains and industries, two notable research frontiers have taken center stage: the growing exploration of the interactive relationship between humans and increasingly intelligent systems and the renewed emphasis on integrating a range of social science and humanities perspectives within AI research. This surge in interest, coupled with the proliferation of publications and diverse terminologies, has led to a complex landscape where theoretical inconsistency and conceptual (...) confusion abound. In response, this work aims to bridge critical gaps by (1) exploring how recent studies in the field of human–AI interaction define their terminologies and fundamental concepts (i.e., knowledge, intelligence, and learning) and (2) developing a novel conceptual overview that facilitates navigation through the diversity of concepts, including new paradigms in AI that integrate perspectives from social sciences and humanities. Our findings reveal that researchers in this cross-sectional field understand that intelligence is more frequently seen as intricately linked with knowledge, with a mutually causal relationship between the two. Despite the proliferation of terminologies across different areas of expertise, such as human-centric design, human–AI collaborative arrangements, and synergy as a process of mutual enhancement, the theoretical distinctions among them remain unclear. To address these complexities, we developed a conceptual overview that functions as a paradigm matrix, enabling the identification of tensions arising from the integration of multiple paradigms across different theories and epistemologies from social sciences and humanities. This conceptual overview is designed not to homogenize these perspectives, but to foster dialogue and reflection, allowing researchers to appreciate and leverage the unique strengths and insights each paradigm offers. This paradigm matrix promises to enhance our understanding of the dynamic and multifaceted interaction between humans and AI, paving the way for more coherent and impactful research in this rapidly evolving field.

Este artigo é parte de uma pesquisa mais ampla que analisa os processos sociais e culturais envolvidos na condição da monoparentalidade feminina, enfatizando jornadas exaustivas e responsabilização pela economia dos cuidados e reprodução social da vida. Objetiva-se analisar como as estruturas opressoras patriarcais afetam e refletem nas vivências de mulheres que exercem a maternidade solo. A investigação se deu a partir da seguinte questão: Como a sobrecarga e os estereótipos promovidos pelo patriarcado colonialista, por meio da divisão sexual do trabalho, (...) atingem as mães solo? Ancora-se na abordagem da história oral e autoetnográfica, na pesquisa social-qualitativa bibliográfica e no estudo de campo, sob a perspectiva espistemológica feminista interseccional e decolonial. Constata-se que os empecilhos promovidos por tais estruturas opressoras impedem ou adiam processos emancipatórios e alocam famílias monoparentais femininas em lugares de vulnerabilidade financeira, afetiva e social. Entretanto, apesar destes obstáculos, as mães solo do recorte pesquisado, resistem e lutam pela emancipação financeira, social e emocional. (shrink)

The pandemic caused by the new coronavirus has sparked discussions among health professionals about the role of food and nutrition in the infectious condition caused by the SARS-CoV-2 virus in different population groups. Malnutrition, including obesity, may reflect more severe outcomes in the physiopathology of infection and systemic responses caused by COVID-19. The present work aims to make considerations directed to the nutritionist about the susceptibility of COVID-19 in individuals submitted to malnutrition, highlighting possible outcomes of the disease and the (...) importance of nutritional care in maintaining the health of these patients. Therefore, maintaining a good nutritional status of these patients, combined with an adequate level of micronutrients will not guarantee protection against infection caused by COVID-19, however, it is essential to minimize the risks of worsening this disease.

The notion of fitness is usually equated to reproductive success. However, this actualist approach presents some difficulties, mainly the explanatory circularity problem, which have lead philosophers of biology to offer alternative definitions in which fitness and reproductive success are distinguished. In this paper, we argue that none of these alternatives is satisfactory and, inspired by Mumford and Anjum’s dispositional theory of causation, we offer a definition of fitness as a causal dispositional property. We argue that, under this framework, the distinctiveness (...) that biologists usually attribute to fitness—namely, the fact that fitness is something different from both the physical traits of an organism and the number of offspring it leaves—can be explained, and the main problems associated with the concept of fitness can be solved. Firstly, we introduce Mumford and Anjum's dispositional theory of causation and present our definition of fitness as a causal disposition. We explain in detail each of the elements involved in our definition, namely: the relationship between fitness and the functional dispositions that compose it, the emergent character of fitness, and the context-sensitivity of fitness. Finally, we explain how fitness and realized fitness, as well as expected and realized fitness are distinguished in our approach to fitness as a causal disposition. (shrink)

In the field of cybernetic systems and more specifically in robotics, one of the fundamental objectives is the detection of anomalies in order to minimize loss of time. Following this idea, this paper proposes the implementation of a Hybrid Intelligent System in four steps to impute the missing values, by combining clustering and regression techniques, followed by balancing and classification tasks. This system applies regression models to each one of the clusters built on the instances of data set. Subsequently, a (...) variety of balancing techniques are applied to improve the classifier’s ability to discern whether it is in an error or a normal state. These techniques support to obtain better classification ratios in which a robot is close to error and allow us to bring the behavior back to a normal state. The experimentation is performed using a modern and public data set, which has been extracted from a component-based robotic system, in which different anomalies are induced by software in their components.

_ Source: _Page Count 21 A historical sequence is said to be hyperfactual whenever it contains facts that have been proved to exist twice, that is, they exist under two alternative courses of events: the factual and the counterfactual. In such cases, we may verify whether multiple courses of action lead to the same outcome. Drawing upon an idea from Nelson Goodman, each section of this article highlights a different type of hyperfactual sequence: those resulting from the turbulence of historical (...) turning points; those resulting from long term historical sequences; and those resulting from competing courses of action. The final section conveys how hyperfactuals represent the resistance of the multiple layers of history to the formalism of subjunctive conditionals. (shrink)

Background: Psychedelics are known for their powerful mental effects due to the activation of 5HT-2A receptors in the brain. During the 1950s and 1960s, research was conducted on these molecules until their criminalization. However, their clinical investigation as therapeutic tools for psychiatric disorders has revived the deontological ethics surrounding this subject. Questions arise as research on their therapeutic outcome becomes a reality. We aim to explore deontological ethics to understand the implications of psychedelics for the clinician, patient, and society. Results: (...) A total of 42 articles were considered for this review. Methods: A methodological search of psychedelic studies from 2017 to 2022 was conducted in PubMed, Scopus, EBSCOhost, and ScienceDirect to address the deontological ethics of clinical psychedelic use. Conclusion: Psychedelics need to be culturally contextualized, epistemic harm minimized and represented to ensure informed consent. Open data and commissions are needed to ensure safe and equal distribution. (shrink)

In this article I draw upon the social ontologies developed by John Searle, Roy Bhaskar, Margaret Archer and Tony Lawson in order to distinguish between power and leadership. To do so, I distinguish the different organizing principles behind natural phenomena, collective phenomena and institutional phenomena, and argue that an understanding of those different organizing principles is essential to a clearer conceptualization of power and leadership. Natural power and cultural power, as I argue, depend upon the organizing principles of natural phenomena, (...) and differ depending on whether those organizing principles have been transformed by humans, in which case it becomes cultural power, or not, in which case it simply is natural power. Leadership emerges with the ability of making other humans share mental states through collective intentionality. Institutional power, in contrast, is connected to the creation of a deontology of rights and obligations that provide what Searle calls desire-independent reasons for action. (shrink)

Warming up prior to competition is a widely accepted strategy to increase players’ readiness and achieve high performances. However, pre-match routines are commonly based on empirical knowledge and strongly influenced by models emerging from elite team practices. The aim of the present study was to identify and analyze current pre-match warm-up practices in elite futsal. Forty-three elite players were analyzed during their pre-match warm-up routines during the Portuguese Futsal Cup Final 8. Warm-up tasks were classified according to duration, type of (...) activity, sequence, and structure. External load variables included the total distance covered, total distance covered per minute, running distance per minute, sprinting distance per minute, number of accelerations per minute, and number of decelerations per minute. Results highlighted that warm-up routines lasted for 27.5 ± 9.2 min and included nine major different tasks. Open-skill activities were prioritized by coaches; competitive and non-competitive futsal-specific tasks were included in 90% of the total warm-up routines, with higher focus on non-competitive tasks. The intensity progressively increased during warm-ups, mainly because of the higher number of accelerations and decelerations per minute. Pre-match warm-up routines strongly endorse futsal-specific and representative tasks in order to establish pre-match settings able to prepare players for the upcoming game. When designing pre-match warm-up routines, coaches should be aware that duration, sequence, and type of tasks may affect players’ acute performance and readiness. (shrink)

O presente artigo pretende discutir como Hegel critica a noção kantiana de lei. A centralidade do sujeito, no que tange ao processo do conhecer, reúne Kant e Hegel no que tange à determinação da realidade. Apesar dessa aproximação, eles se separam na medida em que o sujeito kantiano reconhece o objeto e, diferentemente de Hegel, não se reconhece aí. Tal separação é explorada por Hegel, em sua análise do conceito de liberdade em Kant. Para Hegel, a liberdade kantiana não vai (...) além de uma abstração, enquanto não se deixa determinar. O mesmo raciocínio se estende à lei, pois Hegel entende que Kant opera uma distinção entre a forma e o conteúdo da lei, que não são entendidos como conceitos complementares. Em Hegel, a lei é mais do que uma referência formal. Sem a lei, enquanto determinação histórica, a liberdade permanece uma intenção sem jamais atingir o status necessário de realidade entre os homens. (shrink)

Este artículo refleja el estado de la cuestión de las correspondencias conceptuales, formales, lingüísticas y sociopolíticas del ensayo fílmico / audiovisual respecto a los cánones del ensayo literario. Resume los aportes teóricos esenciales en ambos campos.

Aunque las nuevas tecnologías ponen en alza la manifestación de la subjetividad, faltan estudios orientados hacia la incidencia de estas sobre la construcción del texto ensayístico y sus efectos sociales. Como efecto de este vacío, las referencias canónicas para analizar las correspondencias entre ambas manifestaciones no parecen contemplar experiencias de cinematografías periféricas ni profundizar en prácticas experimentales que dieran respuesta a lo anterior.

This discussion note surveys the main themes explored in Mona Simion’s Shifty Speech and Independent Thought: Epistemic Normativity in Context, paying particular attention to her treatment of kk compatibilism. I argue that in her attempt to establish “epistemic independence”—the disentanglement of epistemic evaluation from pragmatic considerations—Simion overemphasizes the role of context-dependence in Timothy Williamson’s work. I show that if we are to take Williamson at his word, we must appreciate the distinctive anti-sceptical insensitive invariantism at the core of his epistemology—an (...) approach that stands in contrast to both contextualism and subject-sensitive invariantism.

While the notion of chance has been central in discussions over the probabilistic nature of natural selection and genetic drift, its role in the production of variants on which populational sampling takes place has received much less philosophical attention. This article discusses the concept of chance in evolution in the light of contemporary work in evo-devo. We distinguish different levels at which randomness and chance can be defined in this context, and argue that recent research on variability and evolvability demands (...) a causal understanding of variational probabilities under which development acquires a creative, rather than a constraining role in evolution. We then provide a propensity interpretation of variational probabilities that solves a conceptual confusion between causal properties, variational probabilities and extant variation present in the literature, and explore some metaphysical consequences that follow from our interpretation, specifically with regards to the nature of developmental types.

As it is well known, mobile phones have become a basic gadget for any individual that usually stores sensitive information. This mainly motivates the increase in the number of attacks aimed at jeopardizing smartphones, being an extreme concern above all on Android OS, which is the most popular platform in the market. Consequently, a strong effort has been devoted for mitigating mentioned incidents in recent years, even though few researchers have addressed the application of visualization techniques for the analysis of (...) malware. Within this field, the present work proposes the extension of a new technique called Hybrid Unsupervised Exploratory Plots to visualize Android malware datasets. More precisely, the novel Beta-Hebbian Learning (BHL) method is applied for the first time and validated under the frame of Hybrid Unsupervised Exploratory Plots, in conjunction with clustering methods. The informative visualization achieved provides a picture of the structure of the malware families, allowing subsequent analysis of their organization. To validate the Hybrid Unsupervised Exploratory Plot extension and its tuning, the popular Android Malware Genome dataset has been used in the experimental setting. Promising results have been obtained, suggesting that BHL applied in combination with clustering techniques in Hybrid Unsupervised Exploratory Plots are a viable resource for the visualization of malware families.

This paper aims to elucidate factors that contributed to the temporary loss of the European tradition of Taphonomy, developed during the first half of the twentieth century, and its rediscovery and reinvention in North America during the Post-War. Such factors are not restricted to the intellectual content of papers and books produced by researchers but have to do also with linguistic, cultural, historical, and institutional matters, which have shaped and conditioned the reception of ideas and concepts within Paleontology during the (...) twentieth century. These factors include the transition from a multilingual scientific culture to a monolingual one, the shift of palaeontology’s centre from Europe to the United States, and the ideology of researchers, among other factors.

Fueled by ever-growing amounts of (digital) data and advances in artificial intelligence, decision-making in contemporary societies is increasingly delegated to automated processes. Drawing from social science theories and from the emerging body of research about algorithmic appreciation and algorithmic perceptions, the current study explores the extent to which personal characteristics can be linked to perceptions of automated decision-making by AI, and the boundary conditions of these perceptions, namely the extent to which such perceptions differ across media, (public) health, and judicial (...) contexts. Data from a scenario-based survey experiment with a national sample (N = 958) show that people are by and large concerned about risks and have mixed opinions about fairness and usefulness of automated decision-making at a societal level, with general attitudes influenced by individual characteristics. Interestingly, decisions taken automatically by AI were often evaluated on par or even better than human experts for specific decisions. Theoretical and societal implications about these findings are discussed. (shrink)

How can a work of art give us clues about scientific aspects? How can chemistry help a painter enhance his creativity and, above all, preserve the original characteristics of his work? Does an artist require scientific knowledge to innovate or, at least, not to be faked? Other symbiotic fields between art and science are: tattoos, as body art with physical and chemical consequences; pigments, as basic materials with interesting historiographical preparations; spectroscopy diagnosis, as very broad and thorough method of analysis (...) ; biosensors, as one of the applications of new pigments. Note also the interconnection between the several possible paths of science and art, which reflect new challenges with enormous potential investigated through a literature review and the application as a case study in an educational inquiry module.

Psychodrama is an effective psychotherapeutic model but interventions with adolescents require age-tailored techniques that maximize engagement and facilitate communication processes. This study describes a novel adaptation of a therapeutic mask technique to psychodrama with adolescents. Over the course of eight group sessions of psychodrama, five adolescents created their own mask and explored its therapeutic use. Their experiences were captured at the end of each session with the Helpful Aspects of Therapy form, and at the end of the study with the (...) Clinical Change Interview. Awareness/insight/self-understanding, empowerment and relief were the most significant aspects experienced by the adolescents, along with perceived increase of calmness and world connection, satisfaction in interpersonal communication and better emotional expression and regulation. The mask technique was experienced as a playful and engaging task that facilitated insight and interpersonal communication. Findings provide preliminary evidence on the clinical utility of mask-based psychodrama with adolescents. (shrink)

Criticisms of the “container” model of pregnancy picturing female and embryo as separate entities multiply in various philosophical and scientific contexts during the last decades. In this paper, we examine how this model underlies received views of pregnancy in evolutionary biology, in the characterization of the transition from oviparity to viviparity in mammals and in the selectionist explanations of pregnancy as an evolutionary strategy. In contrast, recent evo-devo studies on eutherian reproduction, including the role of inflammation and new maternal cell (...) types, gather evidence in favor of considering pregnancy as an evolved relational novelty. Our thesis is that from this perspective we can identify the emergence of a newhistoricalindividual in evolution. In evo-devo, historical units are conceptualized as evolved entities which fulfill two main criteria, their continuous persistence and their non-exchangeability. As pregnancy can be individuated in this way, we contend that pregnant females are historical individuals. We argue that historical individuality differs from, and coexists with, other views of biological individuality as applied to pregnancy (the physiological, the evolutionary and the ecological one), but brings forward an important new insight which might help dissolve misguided conceptions.

According to the United Nations, human intervention in nature set loose a series of transformations on the Earth’s ecosystems, resulting in a serious disruption of their natural balance. Some of these changes are irreversible and threaten all life on Earth, human life included.

The purpose of this paper is to show (...) how Hannah Arendt’s thought on beginnings, crisis, understanding, meaning and human existence can illuminate and inspire an attempt to retrace the origins of this “ecological” crisis, understood as the human being’s inability to be at home in the world.

The phenomenological reading of psychoanalysis undertook by Michel Henry is surprising in several ways. By inscribing Freud in the philosophical lineage and by affirming that his theses on the unconscious take over (resume), ignoring it, two opposite movements of western metaphysics, Henry intends to show that psychoanalysis has to overcome the primacy of representation in order to get rid of the contradictions that traverse it and that make it a prisoner of a philosophy of consciousness.

O século XVII revelou-se bastante positivo no tocante ao enriquecimento do hagiológio lusitano, tendência que se conseguiu manter activa até inícios de Setecentos. Para além da canonização da Rainha Santa Isabel (1625), em 1671, o Papa Clemente X estende o culto de Gonçalo de Amarante (beatificado em 1561) à Ordem dos Pregadores e a todo o reino de Portugal, com missa e ofício litúrgicos próprios.Seguir-se-ão outros processos de infantas portuguesas, mais prolíferos em termos de produção artística e iconográfica, que decorrem (...) na viragem para o século XVIII. Primeiro, o da Princesa Santa Joana (1693) e, alguns anos depois, o das filhas de D. Sancho I – Teresa, Sancha (1704) e Mafalda (processo iniciado em 1700, embora beatificada apenas em 1792). Estes processos, independentemente do seu sucesso, motivaram uma significativa produção de novas formas de representação. A proximidade com o poder papal, e com os centros de decisão, como o da Sagrada Congregação dos Ritos, levou consequentemente à opção por uma produção romana no tocante à origem das novas imagens.Apesar de motivadas por intuitos de ordem religiosa, no sentido de suscitar a devoção e divulgar o culto, estas encomendas contribuíram não só para a criação de uma nova iconografia, como para o desenvolvimento de novos conceitos estilísticos e de vertentes do gosto. De facto, elas acabam por definir a preponderância das correntes italo-romanas, que marcariam o estilo predominante da pintura portuguesa, ao longo da centúria seguinte. (shrink)

Boffa non-well-founded set theory allows for several distinct sets equal to their respective singletons, the so-called ‘Quine atoms’. Rieger contends that this theory cannot be a faithful description of set-theoretic reality. He argues that, even after granting that there are non-well-founded sets, ‘the extensional nature of sets’ precludes numerically distinct Quine atoms. In this paper we uncover important similarities between Rieger’s argument and how non-rigid structures are conceived within mathematical structuralism. This opens the way for an objection against Rieger, whilst (...) affording the theoretical resources for a defence of Boffa set theory as a faithful description of set-theoretic reality. (shrink)

A cidade nas práticas artísticas [The city in artistic practices] is the result of the work developed, of the presentations and the debates held within the cycle of seminars “The experience of the city between art and philosophy”, held between 3 March 2020 and 16 June 2021 (calendar dramatically compromised by the challenges of the COVID 19 pandemic), one of the main activities of the OBRA project — Fragmentation and Reconfiguration: experiencing the city between art and philosophy, based at IFILNOVA (...) — Philosophy Institute of NOVA, in Lisbon. The book is divided into five parts, relating to each of the artistic disciplines to which the seminars were dedicated – cinema, photography, sound arts, literature and architecture —, which are edited by the organizers responsible for each of them — respectively, Susana Viegas, Humberto Brito, Nuno Fonseca João Oliveira Duarte and Susana Ventura — and composed of the respective narrated accounts of each seminar and of short essays, some merely textual, others graphical or even photographic, which are either in-depth versions of the reflections and positions that were presented and debated by the participants and guests, or works that motivated and inspired the work of the seminars. The seminar cycle and the book now presented here intend to reflect on the role of artistic practices in the representation and reconfiguration of urban experience, trying to understand their different attempts to apprehend and express the fragmentation of aesthetic experience in modern and contemporary cities, as well as to evaluate their contribution to an eventual symbolic and imaginative reconfiguration of that experience. Each section tries, in its own way, to answer questions such as: How do these arts think and reinvent the city? What do they make us feel? And what is their social and political role? For reasons that are easy to understand, Lisbon was the starting point, but other cities were also part of the journey. (shrink)

In this paper I begin by scrutinizing classic approaches to the question of agrammaticality, with a particular focus on Frege and the early Wittgenstein, and try to show that a further step is needed in order to adequately address this topic. I then focus on the later Wittgenstein’s treatment of nonsense-poems and claim that the failure of the Philosophical Investigations as a book is actually connected with Wittgenstein’s recognition that philosophy should be written under the form of poetry. The therapeutic (...) consequences of this view are discussed in connection with Deleuze’s comments on Melville and with Read’s comments on Sass, which offer very different views of agrammaticality.

The focus of social simulation on representing the social world calls for an investigation of whether its implementations are inherently value-laden. In this article, I investigate what kind of thing implementation is in social simulation and consider the extent to which it has moral significance. When the purpose of a computational artefact is simulating human institutions, designers with different value judgements may have rational reasons for developing different implementations. I provide three arguments to show that different implementations amount to taking (...) moral stands via the artefact. First, the meaning of a social simulation is not homogeneous among its users, which indicates that simulations have high interpretive malleability. I place malleability as the condition of simulation to be a metaphorical vehicle for representing the social world, allowing for different value judgements about the institutional world that the artefact is expected to simulate. Second, simulating the social world involves distinguishing between malfunction of the artefact and representation gaps, which reflect the role of meaning in simulating the social world and how meaning may or not remain coherent among the models that constitute a single implementation. Third, social simulations are akin to Kroes’ techno-symbolic artefacts, in which the artefact’s effectiveness relative to a purpose hinges not only on the functional effectiveness of the artefact’s structure, but also on the artefact’s meaning. Meaning, not just technical function, makes implementations morally appraisable relative to a purpose. I investigate Schelling’s model of ethnic residential segregation as an example, in which different implementations amount to taking different moral stands via the artefact. (shrink)

En este artículo conceptualizamos a los mass media como dispositivos sociales de control destinados a reproducir una violencia simbólica que pretende mantener los esquemas de dominación derivados del consenso entre dominantes y dominados. En este contexto, analizamos cómo el término “antisistema” es utilizado por los medios de comunicación de masas, en un sentido claramente peyorativo, para designar a los colectivos que se posicionan en contra del funcionamiento del sistema político y económico actual. Así, intentaremos vislumbrar cómo el discurso dominante consigue (...) crear una vinculación directa entre los grupos que llevan a cabo acciones violentas en las movilizaciones y los movimientos sociales de protesta. El principal objetivo de esta forma de control social es conectar la protesta social con la violencia, y en última instancia, conseguir la criminalización de los movimientos sociales. Argumentamos que este control social persigue luchar contra la idea misma de movilización a favor de un sistema económico alternativo. (shrink)

Cet article vise à examiner la critique wittgensteinienne d’Héraclite et des idées de ce dernier selon lesquelles « tout coule » et « on ne peut entrer deux fois dans la même rivière ». Dans la première section, j’examinerai les sources et les interprétations traditionnelles de ces idées. Dans la seconde section, je discuterai le lien établi par David G.

Dans la troisième section, je m’attacherai aux notes sur Héraclite antérieures à 1931 et je les relierai à la question d’un langage phénoménologique. Puis, dans les sections quatre et cinq, je critiquerai le portrait que dresse Hintikka de Wittgenstein en phénoménologue et je fournirai une analyse approfondie de la phénoménologie de Wittgenstein. Enfin, dans la sixième section, je tenterai de faire une synthèse de l’ensemble et de porter un nouveau regard sur la dernière philosophie de Wittgenstein.The aim of this paper is to focus on Wittgenstein’s criticism of Heraclitus and his ideas that « everything flows » and that « one cannot step into the same river twice ».

Stern’s association of Wittgenstein’s remarks on river imagery with his study of Plato after 1931. In the third section, I scrutinize the pre-1931 notes on Heraclitus and link them to the question of a phenomenological language. Then, in sections four and five, I criticize Hintikka’s portrait of Wittgenstein as a phenomenologist and provide an in-depth analysis of Wittgenstein’s phenomenology. Finally, in section six, I attempt to draw everything back together and take a fresh look at Wittgenstein’s later philosophy. (shrink)
