Baumard suggests that the advent, through phenotypic plasticity mechanisms, of future-oriented preferences and creative mindsets in eighteenth-century Great Britain explains the wave of innovations that drove the British Industrial Revolution. We argue that, although this approach is promising, Baumard's model would benefit from being supplemented by demographic, economic, and sociological explanations independent of Life History Theory.

Le rule of law et l’ordre public sont deux composantes essentielles du vivre ensemble dans la société britannique. La présente étude a pour objet de revenir sur la conception de ces deux notions qui sont de plus en plus en tension dans un contexte où les impératifs d’ordre public semblent supplanter les présupposés libéraux qui fondent le rule of law.

Major depression is associated with a decrease of 1st person visual perspective in autobiographical memory, even after full remission. This study aimed to examine visual perspective in healthy never-depressed subjects presenting with either genetic or psychological vulnerability for depression. Sixty healthy participants performed the Autobiographical Memory Test with an assessment of visual perspective. Genetic vulnerability was defined by the presence of at least one S or LG allele of the polymorphism of the serotonin-transporter-linked promoter region . Psychological vulnerability was defined (...) by high scores of harm avoidance measured by the Temperament and Character Inventory. Life stress exposure, depressive mood, rumination, and familial history of depression were assessed through standardized procedures. Visual perspective for positive memories was independently predicted by both harm avoidance and a gene by environment interaction between the 5-HTTLPR polymorphism and life stress exposure. Visual perspective and vulnerability for depression may share some biological bases. (shrink)

In algorithmic randomness, when one wants to define a randomness notion with respect to some non-computable measure λ, a choice needs to be made. One approach is to allow randomness tests to access the measure λ as an oracle . The other approach is the opposite one, where the randomness tests are completely effective and do not have access to the information contained in λ . While the Hippocratic approach is in general much more restrictive, there are cases where the (...) two coincide. The first author showed in 2010 that in the particular case where the notion of randomness considered is Martin-Löf randomness and the measure λ is a Bernoulli measure, classical randomness and Hippocratic randomness coincide. In this paper, we prove that this result no longer holds for other notions of randomness, namely computable randomness and stochasticity. (shrink)

Macrocephaly is present in about 2–5% of the general population. It can be found as an isolated benign trait or as part of a syndromic condition. Brain overgrowth has been associated with neurodevelopmental disorders such as autism during the first year of life, however, evidence remains inconclusive. Furthermore, most of the studies have involved pathological or high-risk populations, but little is known about the effects of brain overgrowth on neurodevelopment in otherwise neurotypical infants. We investigated the impact of brain overgrowth (...) on basic perceptual learning processes during the first year of life. We recorded high density electroencephalograms in 116 full-term healthy infants aged between 3 and 11 months, 35 macrocephalic and 81 normocephalic classified according to the WHO head circumference norms. We used an adapted oddball paradigm, time-frequency analyses, and auditory event-related brain potentials to investigate differences between groups. We show that brain overgrowth has a significant impact on repetition effects and change detection response in the 10–20 Hz frequency band, and in N450 latency, suggesting that these correlates of sensorial learning processes are sensitive to brain overgrowth during the first year of life.

Sleep is mandatory in most animals that have the nervous system and is universally observed in model organisms ranging from the nematodes, zebrafish, to mammals. However, it is unclear whether different sleep states fulfill common functions and are driven by shared mechanisms in these different animal species. Mammals and birds exhibit two obviously distinct states of sleep, i.e., non-rapid eye movement sleep and rapid eye movement sleep, but it is unknown why sleep should be so segregated. Studying sleep in other (...) animal models might give us clues that help solve this puzzle. Recent studies suggest that REM sleep, or ancestral forms of REM sleep might be found in non-mammalian or -avian species such as reptiles. These observations suggest that REM sleep and NREM sleep evolved earlier than previously thought. In this review, we discuss the evolutionary origin of the distinct REM/NREM sleep states to gain insight into the mechanistic and functional reason for these two different types of sleep. (shrink)

In the present research, we validated a new scale developed from self-determination theory (SDT) to assess the functional meaning of cash rewards offered in the workplace. According to SDT, rewards can take on different meanings based on the way they are perceived by individuals. In a series of three studies in different socioeconomic contexts, we replicated the two-factorial structure of the scale measuring respectively workplace cash rewards’ informative and controlling meanings. In Study 1, we validated the English version of the (...) scale by exploring and then confirming its two-factor structure with two English-speaking employee samples. We further replicated its two-factor structure in a French-speaking employee sample of employees in Study 2 and in a Greek-speaking employee sample in Study 3, allowing us to validate its French and Greek version. Results from our three studies show how distinct meanings attributed to cash rewards, i.e., informative or controlling, relate differently to autonomous and controlled forms of motivation based on SDT. These findings suggest that workplace cash rewards differently influence employees’ motivation depending on whether they are perceived as informative or controlling, thus providing empirical evidence for the theoretical and practical implications of SDT’s concept of functional meaning of cash rewards. Our research contributes to the assessment and understanding of employees’ experience of workplace cash rewards and provides empirical evidence that the concept of the functional meaning of cash rewards is a distinct concept from other money-related concepts such as subjective pay satisfaction, performance-contingent rewards, and financially contingent self-worth.

Review of Fernando Vidal's _Performing brains on screen_ (Amsterdam 2022).

This paper explores the conditions favouring or inhibiting the implementation of strategic corporate social responsibility policies in the context of global value chains. Using transaction cost theory, we specify the economic and behavioural issues raised by strategic CSR policies. We show that the existence of market rewards for such policies does not constitute a solution per se, but tends to increase the difficulties that value chain members face. Bringing TCT into the analysis of the diffusion of strategic CSR policies in (...) GVCs helps us to make different contributions. We first theoretically identify some limiting conditions of strategic CSR policies in GVCs. We also contribute to developing a more robust theoretical perspective for CSR in GVC research, which remains underdeveloped and mostly driven by empirical case studies. Finally, we shed light on new research questions and topics that could guide major theoretical and empirical investigations in the capacity of GVCs members to bypass the numerous difficulties involved in the implementation of strategic CSR policies.

Although the concept of corporate social responsibility is fundamentally multidimensional, most studies use composite scores to assess corporate social performance. How relevant are such composite scores? How the CSR dimensions are weighted? Should the weighting scheme be the same across sectors? This article proposes an original weighting scheme of CSR strengths and concerns, at the sector level, which is proportional to media and nongovernmental organizations scrutiny. The authors show that previous CSP assessments underweight environmental and corporate governance concerns. Moreover, findings (...) suggest that firms that are exposed to the closest scrutiny are usually criticized on one single dimension: for instance, banks for bad corporate governance, and basic-resource firms for environmental damage. Composite scores based on equal weights hence misrepresent CSP and the difference in CSR between sectors. (shrink)

While corporate social responsibility is recognized as taking on various national meanings and practices, research has not sufficiently investigated how multinational companies simultaneously achieve global CSR integration and local CSR adaptation. Building on a qualitative case study carried out at ASICS, an MNC headquartered in Japan, we show how this organizational dilemma may be solved through hybridization work, a form of institutional work performed by CSR managers in subsidiaries to combine and adapt different institutional approaches to CSR. By developing the (...) notion of hybridization work, we contribute by revealing a set of practices that contribute to institutional change within organizations and enriching the study of CSR organizational change and international business by showing how hybridization Work leads to a greater organizational integration between core and periphery, and by identifying the triggering factors for subsidiary initiative in CSR.

Antoine Arnauld and Pierre Nicole were philosophers and theologians associated with Port-Royal Abbey, a centre of the Catholic Jansenist movement in seventeenth-century France. Their enormously influential Logic or the Art of Thinking, which went through five editions in their lifetimes, treats topics in logic, language, theory of knowledge and metaphysics, and also articulates the response of 'heretical' Jansenist Catholicism to orthodox Catholic and Protestant views on grace, free will and the sacraments. In attempting to combine the categorical theory of (...) the proposition with a Cartesian account of knowledge, their Logic represents the classical view of judgment which inspired the modern transformation in logic and semantic theory by Frege, Russell, Wittgenstein and recent philosophers. This edition presents a new translation of the text, together with a historical introduction and suggestions for further reading. (shrink)

Aurélien Djian | : L’ambition de cet article est double. Il s’agit d’abord de fixer le contexte philosophique qui sous-tend le débat entre Derrida et Marion en 1999, à l’Université de Villanova, et de réviser la perspective qui y est formulée selon laquelle le destin de la phénoménologie est intimement lié à une décision à prendre à l’égard du concept d’horizon : « il n’y a pas de phénoménologie sans horizon », affirme Derrida à Marion, il faut donc la (...) dépasser ; « la dernière étape en vue d’une véritable phénoménologie serait d’abandonner le concept d’horizon », rétorque Marion à Derrida. Cette révision de perspective nous conduira alors, dans un second temps, à restituer, en se servant de l’histoire du concept d’horizon comme fil directeur heuristique, le sens de ce que nous appellerons l’histoire française de l’herméneutique phénoménologique, dont l’unité, par-delà la multiplicité des étiquettes, réside dans le partage d’une même définition de l’activité philosophique, comme tentative de laisser se montrer soi-même à partir de soi-même le phénomène par excellence, et, avec et contre le second Heidegger, d’une même exigence de dépassement de l’horizon, solidaire de la métaphysique moderne de la subjectivité. Le principe d’une telle reconstruction permettra enfin d’envisager la possibilité d’une histoire différenciée des concepts alternatifs de phénoménologie et d’horizon, qui reste à écrire. | : The task of this article is twofold. First, it is meant to sketch out the philosophical context within which the Derrida/Marion debate that happened in 1999 at the university of Villanova took place, and to overhaul the perspective that it puts forward, that the destiny of phenomenology itself is linked at the abandon of the concept of horizon : “Without horizon there is no phenomenology”, argues Derrida against Marion ; “the last step for a real phenomenology would be to give up the concept of horizon”, answers Marion to Derrida. This overhaul will then leads us to use the history of the concept of horizon as a heuristical guiding thread to flesh out what makes the unity of what we can call the French history of hermeneutical phenomenology, that is to say, firstly, the sharing of the same definition of philosophy, as the attempt to let the distinctive phenomenon be seen as it shows itself by itself. And, secondly, with and against the second Heidegger, of the same requirement of overcoming the horizon, as it is committed to the modern metaphysics of subjectivity. The principle on which such a reconstruction is based will finally allow us to consider the idea of a differentiated history of the alternative concepts of phenomenology and horizon. History which is yet to come. (shrink)

This contribution aims at describing the experiences of Deep Brain Stimulation (DBS) as discussed on Internet forums. Since the 2000s, increasing attention has been paid to health practices associated with the use of the Internet, whether by medical professionals, public authorities or researchers in the social sciences. We know that Internet is used by patients with Parkinson’s disease, in order to discuss about their lived experiences. This contribution will present how these Internet users address the specific theme of DBS. We (...) will examine how their use and the information sharing associated to it participate in the “shaping” of the lived experience of deep cerebral stimulation. This contribution will be introduced by an analysis of the state-of-the-art in sociological and anthropological international research on the topic of “Internet health”. On the basis of this analysis, it will propose a framework to describe and understand the various uses of the web that are made to give an account of the experience of stimulation. The existence of collective mobilizations in Parkinson’s disease, an old Internet experience and media oppositions concerning certain antiparkinsonian drugs, are conditions which push us to question these themes concerning DBS. This paper is a description, for the first time, of roles played by the users of these Internet forums and the different online activities produced about DBS subject. In an ethnographic perspective, we had to imagine that we were an Internet user seeking patient experiences with this surgical procedure to understand these interactions about DBS. The main goal of this contribution is to describe the attention paid by users for medical information about DBS in the identity and self-help process. The interest of such an approach is to open an anthropological reflection on the place and the role of the medical representations in the testimonies of experience of the disease or the treatments.

While psychologists and political scientists have long investigated issues of interest to philosophers, the development of political experimental philosophy has remained limited. This slow progress is surprising, given that political philosophers commonly acknowledge the relevance of empirical data for normative theorizing. In this chapter, we illustrate the importance of empirical data by outlining recent developments in three domains related to theories of justice, where empirical results reinforce or endanger popular philosophical theories. Our first showcase concerns the boundaries of the concept (...) of fairness. While both libertarian thinkers and social egalitarians have united in rejecting the concept of natural injustice, we show that people do consider that unpreventable natural inequalities can be described as unfair. Second, we take the example of impartiality devices, such as the veil of ignorance or the idea of an impartial spectator, to show that such devices are efficient at shifting people’s intuitions in a more impartial manner. Third, we review empirical data on fairness intuitions to show that people conform to a pluralist theory of justice, valuing desert, needs-satisfaction, and equality at the same time. However, distribution according to desert enjoys a privileged position: people mostly care for the satisfaction of basic needs of deserving recipients, and people are willing to tolerate large inequalities in meritocratic contexts. The centrality of desert leads to dilemmas for mainstream egalitarian theorists, as theories that do not recognize the value of desert could fail to find support or legitimacy within the population.

Why do policymakers and economists within a policymaking institution choose to throw away a model and to develop an alternative one? Why do they choose to stick to an existing model? This article contributes to the literature on the history and philosophy of modelling by answering these questions. It delves into the dynamics of persistence, change, and building practices of macroeconomic modelling, using the case of forecasting models at the Bank of England (1974–2014). Based on archives and interviews, we document (...) the multiple factors at play in model building and model change. We identify three sets of factors: the agency of modellers, institutional factors, and the material factor. Our investigation shows the diversity of explanations behind the decision to change a model: each time, model replacement resulted from a different combination of the three types of factors.

We review several no-go theorems attributed to Gisin and Hardy, Conway and Kochen purporting the impossibility of Lorentz-invariant deterministic hidden-variable model for explaining quantum nonlocality. Those theorems claim that the only known solution to escape the conclusions is either to accept a preferred reference frame or to abandon the hidden-variable program altogether. Here we present a different alternative based on a foliation dependent framework adapted to deterministic hidden variables. We analyse the impact of such an approach on Bohmian mechanics and (...) show that retrocausation necessarily comes out without time-loop paradox. (shrink)

abstract The moral value of distributive equality constitutes one of the most contentious debates in political philosophy. Following Frankfurt, many philosophers have claimed that the intuitive appeal of equality is illusory and that egalitarian intuitions are fundamentally intuitions about the importance of satisfying basic needs. According to this argument, our intuitions tell us that inequality ceases to matter once a certain threshold has been reached. Despite the widespread appeal to intuitions regarding this issue, few empirical studies have tried to assess (...) whether Frankfurt and his followers are right in claiming the lack of intuitiveness of equality per se. In a series of three experiments, we show that experimental evidence does not allow us to settle the intuitiveness of each theory: laypeople are divided in the consideration of the respective importance of needs and equality. While our results do show that laypeople attach special importance to needs‐fulfilment, it also seems that they are divided when it comes to the importance they grant to equality once needs are fulfilled. No theory is unanimously backed by participants, and it seems that, fundamentally, divisions among philosophers reflect deep divisions among people. (shrink)

This paper is meant to provide a theoretical contribution to the Business and Society field, in line with Pasquero proposition (1996) to develop a constructivist research agenda on Business and Society issues, i.e. an agenda accounting for the dynamics and the socio-cognitive construction of CSR and stakeholder concepts. Among the different theoretical perspectives that may be good candidates to overcome several difficulties related to that lack in the B&S field, wepropose that some of Michel Callon’s sociological works are of particular (...) value. By bringing together those two traditionally separated areas of research, we will try to show how Callon’s concepts may shed new light on B&S traditional research issues, by answering, reformulating research questions or opening new research directions.

Since the use of systems of satellite positioning such as the global positioning system, applications have tried to locate vehicles on maps representing the environment with their attributes. For one decade, this has led to both localization and navigation services for users. Recently, new researches have begun in order to extend the functionalities of the existing systems and thus to develop new applications using these technologies in the design of driver assistance systems. These new systems will indeed allow us to (...) anticipate road departures or prevent overspeed turn approaches. Nevertheless, to deploy such new functionalities, it is imperative to ensure the association of vehicle position with one of the roadmap segments. In this article, we propose a new approach based on the belief theory taking into account the imperfections of available data in order to ensure the positioning and tracking of a vehicle on a roadmap and to manage conflicts and ambiguities using a multi-hypotheses decision.

We examine here the evolution of Merleau-Ponty’s philosophy of history from Humanism and Terror to the 1955 course on “Institution in Personal and Public History” in order to explain what makes it “ambiguous.” This evolution is explained by the desire to understand history according to intersubjective praxis and the dialectical scheme of historical institution. The articulation of these two levels allows Merleau-Ponty to develop a philosophy of historical productivity, that is, a conception of history as a practical process that is (...) open, unfinished, and continually “instituting” by virtue of the always revived and entangled taking up of human actions. Therefore, the more general challenge is to define the specificity of a thought of history that unfolds from the permanent and central concern for the achievement of human coexistence. (shrink)

In 2014, the European Court of Justice recognized, for the first time, that severe obesity could be considered as a disability at work. This recognition, not yet applied in France, emerges in a context where obesity as a disease to treat seems to be consensus. The development of obesity surgery and its medical results are reinforcing this perspective. The lack of public debate in France on this potential handicap recognition of obesity, and simultaneously the frequent use of the term disability (...) or “de-disability” by people operated to discuss the effects of this surgery are two findings at the origin of the article. In an ethnographic approach, it is proposed to give an account of the way in which people, experimenting this corporal transformation, participate in redefining obesity, bariatric surgery and disability, before the debates and political decisions that could trigger this recognition of disability. Starting from the emic neologism “de-disability,” the thread of the article, it is questioned the idea of exit from disability and entry into normality, showing that these situations confront the people operated with new social injunctions and examine the relationship between disability and normality in an original way.

The purpose of this paper is to stress the constancy of the Husserlian conception of sensible contents. I argue that Husserl, despite some significant changes in his philosophical views between 1901 and 1913, always maintained that sensations have a founding role to play in perceptual experience. The proposed interpretation is build against the idea of a scission in Husserl’s work as regards the status of sensations—an idea which became widespread due to the so-called Fregean readings of phenomenology. Even if the (...) notion of sense gains in importance in the Ideas, I argue that this does not discredit the sensuous stuff when it comes to the constitution of perceptual objects. (shrink)

Though the rise of social media has provided countless advantages and possibilities, both within and without the domain of sports, recent years have also seen some more detrimental aspects of these technologies come to light. In particular, the widespread social media culture surrounding fitness – ‘fitspiration’ – warrants attention for the way it encourages self-sexualization and -objectification, thereby epitomizing a wider issue with photo-based social media in general. Though the negative impact of fitspiration has been well documented, what is less (...) understood are the ways it potentially impacts and molds moral psychology, and how these same aspects may come to influence digital sports subcultures more broadly. In this theoretical paper, I rely on the insights of Friedrich Nietzsche to analyze the moral significance of a culture like fitspiration becoming normalized and influential in structuring and informing self-understanding, notions of value, and how to flourish in life. Using two doctrines central to Nietzsche’s philosophy—The Last Man and his conception of the ’higher self’ – I argue that fitspiration involves a form of hedonism that is potentially harmful to the pursuit and achievement of human flourishing. Through fitspiration, desire is elevated to a central moral principle, underlying the way users both consume and produce its content, catering simultaneously to their desires for external validation and instant gratification. It thereby creates conditions which foster a culture in adherence to the ethos of The Last Man. In doing so, I argue it impedes the cultivation of the virtues and higher values which define the higher individual, regarded by Nietzsche as essential for human flourishing. However, drawing on the ethical framework of the higher individual provides the philosophical and psychological resources with which resisting and overcoming the more harmful temptations of these trends may be possible.

In 1927 Louis de Broglie proposed an alternative approach to standard quantum mechanics known as the double solution program (DSP) where particles are represented as bunched fields or solitons guided by a base (weaker) wave. DSP evolved as the famous de Broglie-Bohm pilot wave interpretation (PWI) also known as Bohmian mechanics but the general idea to use solitons guided by a base wave to reproduce the dynamics of the PWI was abandoned. Here we propose a nonlinear scalar field theory able (...) to reproduce the PWI for the Schrödinger and Klein–Gordon guiding waves. Our model relies on a relativistic ‘phase harmony’ condition locking the phases of the solitonic particle and the guiding wave. We also discuss an extension of the theory for the N particles cases in presence of entanglement and external (classical) electromagnectic fields. (shrink)

This paper focuses on the main claim of Umberto Eco’s Open Work, according to which any work of art is an inherently ambiguous message, i.e. is inexhaustible, or in principle likely to be the object of an infinite number of interpretations. It does so, first, by restricting itself to the specific topic of the literary work of art, and, secondly, by making a detour, that Eco himself suggests, though he does not really explore it, via Sartre’s ontological phenomenology. This detour (...) will eventually lead the reader from Being and Nothingness to What is Literature?; from Sartre’s “theory of the phenomenon” to his description of the poetic and prosaic attitude; and from a theory of literature qua ambiguity-inexhaustibility to that of openness qua esthetic phenomenon. Finally, it is the capacity of Sartre’s phenomenology to ultimately clarify, or provide a foundation to, Eco’s own theory, as well as the latter’s originality with regard to the former, that will be studied and accounted for.

The purpose of this paper is to show how the phenomenology of the body developed in his late writings by the Czech philosopher Jan Patočka can be seen as the final stage of the archaeology of the Lebenswelt developed by Edmund Husserl and reshaped by Martin Heidegger. According to this exegetical and philosophical hypothesis, only a phenomenology of the body can be a serious attempt to resolve the conflict between the so-called “manifest” and “scientific” images of the world, in which (...) the concept of Lebenswelt is rooted. The peculiarity of Jan Patočka’s phenomenology of the body is to stress the strong connection between the notion of sense, the affective dimension of human experience and the necessity of taking into consideration a “bodily” point of view on the experience.

Female empowerment has long been a prominent social concern in Western culture. With the rise of social media, the quest for female empowerment has become embodied in self-presentational practices, occurring conspicuously throughout the Instagram fitness subculture: ‘fitspiration’. Here, female empowerment is merged with the body-centrality inherent to fitness, and the self-sexualization that has become characteristic of both photo-based social media in general, and fitspiration in particular. Meanwhile, an extensive body of research highlights numerous detrimental effects of self-sexualization on women. Evidently, (...) something seems awry with the implied proposition ‘sexualization as empowerment’. Drawing on Friedrich Nietzsche’s philosophy of power and its relationship to human flourishing, this article aims to critically examine the conception of female empowerment expressed in fitspiration and to conceptualize a philosophically compelling reformulation of universal human empowerment. I argue that what is commonly conceived of as female empowerment in trends like fitspiration—delineated in its explicit relationship to sexualization—may be seriously flawed. Rejecting this understanding in favor of a Nietzschean universal alternative may prove beneficial to individuals both within and without the contemporary fitness culture. (shrink)

The capacity to stabilize the content of attention over time varies among individuals, and its impairment is a hallmark of several mental illnesses. Impairments in sustained attention in patients with attention disorders have been associated with increased trial-to-trial variability in reaction time and event-related potential deficits during attention tasks. At present, it is unclear whether the ability to sustain attention and its underlying brain circuitry are transformable through training. Here, we show, with dichotic listening task performance and electroencephalography, that training (...) attention, as cultivated by meditation, can improve the ability to sustain atten- tion. Three months of intensive meditation training reduced variability in attentional processing of target tones, as indicated by both enhanced theta-band phase consistency of oscillatory neural responses over anterior brain areas and reduced reaction time variability. Furthermore, those individuals who showed the greatest increase in neural response consistency showed the largest decrease in behav- ioral response variability. Notably, we also observed reduced variability in neural processing, in particular in low-frequency bands, regardless of whether the deviant tone was attended or unattended. Focused attention meditation may thus affect both distracter and target processing, perhaps by enhancing entrainment of neuronal oscillations to sensory input rhythms, a mechanism important for controlling the content of attention. These novel findings highlight the mechanisms underlying focused attention meditation and support the notion that mental training can significantly affect attention and brain function. (shrink)

Alors que la conception habituelle de l’espace et du temps insiste sur la différence insurmontable de leur nature, sur leur incommensurabilité malgré leur coexistence (la réalité se donnant simultanément dans l’espace et le temps), la conception philosophique à laquelle nous voudrions faire droit ici revendique leur articulation.

Dentro de la riquísima literatura producida en el círculo del poder abasí entre los siglos VIII y X, el Occidente islámico (es decir, al-Andalus, el Magreb y las islas del Mediterráneo occidental) ocupa un lugar insignificante, a pesar de las pretensiones universalistas que tenían sus autores. Este silencio afecta a todos los géneros literarios, con excepción de la geografía, que experimentó un gran desarrollo en ese periodo. ¿Cómo puede explicarse esta circunstancia? Contextualizar estos textos permite considerar dos argumentos. El primero (...) es la ausencia de datos históricos sobre Occidente a disposición de los autores de Oriente, lo que nos lleva a poner en cuestión la cronología de la formación de comunidades de sabios en el Occidente islámico, así como la circulación del saber en el mundo islámico. También se puede considerar que este silencio resulta de un desinterés deliberado respecto a Occidente, directamente vinculado con cuestiones políticas y geopolíticas. Desde una perspectiva imperial, invisibilizar el Occidente islámico -tierra de rebeldía desde mediados del siglo VIII- contribuye a diseñar un mundo ideal, cuya estructura muestra de manera implícita la centralidad de Bagdad.
