Le voyageur marocain Ibn Battuta, né en 1304, a consigné dans sa relation de voyage, connue sous le nom de Rihla, de nombreux éléments sur Constantinople. Le caractère tardif de l’auteur, vivant à une époque où Byzance est censée décliner, a longtemps conduit à négliger son apport. En outre, des invraisemblances chronologiques et les préjugés d’un musulman face à une ville chrétienne ont parfois laissé penser que cette description ne reposait pas sur un séjour réel. Or la confrontation du texte (...) avec les sources byzantines permet d’accréditer plusieurs détails fournis par le voyageur sur la topographie et la vie quotidienne. Bien plus, l’insertion de certaines notations concrètes dans des passages crédibles fait d’Ibn Battuta une source nouvelle précieuse sur certains points. Il apparaît donc que le voyageur s’est effectivement rendu à Constantinople. Il n’en reste pas moins que son regard est marqué par la culture d’un savant musulman. Il importe donc de déceler ce que sa vision doit au jugement porté sur une religion du Livre et à la tradition de la géographie arabe, prolixe sur le monde byzantin. On aboutit finalement à l’idée que la description de Constantinople par Ibn Battuta relève d’un genre double, de deux veines davantage juxtaposées que mêlées: d’une part, un témoignage rapportant des éléments objectifs, et, d’autre part, un regard subjectif imposant une grille de lecture de ces éléments.

Much of cognitive science is committed to the modular approach to the study of cognition. The core of this approach consists of a pair of assumptions - the anatomical and the functional modularity assumptions - which motivate two kinds of inference: the anatomical and the functional modularity inferences. The legitimacy of both of these inferences has been strongly challenged, a situation that has had surprisingly little impact on most theorizing in the field. Following the introduction of an important, yet rarely (...) made, distinction between two functional concepts - the distinction between cognitive working and cognitive role - this paper analyses these kinds of inference, and refocuses the attention on new aspects of their main limitations. It is argued that both the anatomical and functional modularity inferences can, and do, operate in three distinct modes in contemporary cognitive science, and that seeing this is essential to understanding both the power and the limitations of these methodological tools.

Sufficientarian theories of distributive justice are often considered to be vulnerable to the ‘blindness to inequality and other values objection’. This objection targets their commitment to holding the moral irrelevance of requirements of justice above absolute thresholds of advantage, making them insufficiently sensitive to egalitarian moral concerns that do have relevance for justice. This paper explores how sufficientarians could reply to this objection. Particularly, I claim that, if we accept that the force of the aforementioned objection comes from relational, and (...) not distributive, inequalities, different strategies are open for sufficientarians in order to be sensitive to these concerns. Drawing on recent literature about the relation between distributive and relational egalitarianism, and the possibility of reducing one to the other, strategies of ‘internalizing’ and ‘externalizing’ relational egalitarian concerns to a distributive sufficientarian framework are explored. In turn, I suggest that both strategies fail in their standard versions, but argue that a particular ‘hybrid view’ about justice is an attractive candidate for the sufficientarian theorist. (shrink)

The purpose of this survey is twofold: (1) to place some centralthemes of epistemic logic in a general epistemological context,and (2) to outline a new framework for epistemic logic developedjointly with S. Andur Pedersen unifying some key ``mainstream''epistemological concerns with the ``formal'' epistemologicalapparatus.

It is often assumed that chemistry was a typical positivistic science as long as chemists used atomic and molecular models as mere fictions and denied any concern with their real existence. Even when they use notions such as molecular orbitals chemists do not reify them and often claim that they are mere models or instrumental artefacts. However a glimpse on the history of chemistry in the longue durée suggests that such denials of the ontological status of chemical entities do not (...) testify for any specific allegiance of chemists to positivism. Rather it suggests that the dilemma positivism vs realism is inappropriate for characterizing the ontology of chemistry. This alternative shaped at the turn of the twentieth century in the context of controversies about atomic physics does not take into account the major concern of chemists, i.e. making up things. Only by considering what matters for chemists, their matters of concern rather than their matter theories, can we expect to get an insight on their ontological assumptions. The argumentation based on historical data is twofold. It is wellknown that generating new substances out of initial ingredients which is the raison d'être of chemistry raised a vexing puzzle which has been alternatively solved with the Aristotelian notion of mixt and the Lavoisieran notion of compound. I argue that an essential tension remains intrinsic in chemistry between the two conceptual frameworks. The second section tries to make sense of the long tradition in chemistry of ontological noncommitment. I argue that what is usually considered as a denial of the existence of the basic units of matter would be better characterized as a focus on more important actors on the chemical stage. (shrink)

This discussion paper proposes that a meaningful distinction between science and technoscience can be found at the level of the objects of research. Both notions intermingle in the attitudes, intentions, programs and projects of researchers and research institutions – that is, on the side of the subjects of research. But the difference between science and technoscience becomes more explicit when research results are presented in particular settings and when the objects of research are exhibited for the specific interest they hold. (...) When an experiment is presented as scientific evidence, which confirms or disconfirms a hypothesis, this agrees with traditional conceptions of science. When organic molecules are presented for their capacity to serve individually as electric wires that carry surprisingly large currents, this would be a hallmark of technoscience. Accordingly, we propose research on the ontology of research objects. The focus on the material presence of research objects makes this a specifically philosophical project. (shrink)

My aim in this paper is twofold. First, I provide an analysis of the notion of cognitive homology. In contrast with the well-known concept of structural homology in biology—defined as the same structure in different animals regardless of form and function—the notion of cognitive homology captures the idea that the basic cognitive contribution of a given homologous brain structure tends to remain stable over long evolutionary time scales. Second, I argue that this notion provides a powerful conceptual tool for the (...) study of cognition. Since a cognitive homology will often consist of an evolutionarily conserved relationship between a homologous brain structure and its basic cognitive contribution, such structure–function mappings can be conceived as basic building blocks of human cognition. (shrink)

Neural reuse theories suggest that, in the course of evolution, a brain structure may acquire or lose a number of cognitive uses while maintaining its cognitive workings (or low-level operations) fixed. This, in turn, suggests that homologous structures may have very different cognitive uses, while sharing the same workings. And this, essentially, is homology thinking applied to brain function.

There is a feeling of dissatisfaction with the traditional way of defining the A-theories of time. One reason is that these definitions rest on an ontological question—‘Do the future and the past exist?’—to which no non-speculative answer can be provided. Another reason is that these definitions fail to distinguish between various A-theories of time at all times and, therefore, cannot be regarded as essential to them. In the present paper, I make a fresh start in the debate, by introducing two (...) questions whose specific answers allow one to get a comprehensive categorization of the A-theories of time. This alternative way of defining the A-theories of time addresses the two above-mentioned issues and reveals the metaphysical singularity of underrated theories, such as the growing block theory.

The promises of nanotechnology have been framed by a variety of metaphors, that not only channel the attention of the public, orient the questions asked by researchers, and convey epistemic choices closely linked to ethical preferences. In particular, the image of the ‘therapeutic missile’ commonly used to present targeted drug delivery devices emphasizes precision, control, surveillance and efficiency. Such values are highly praised in the current context of crisis of pharmaceutical innovation where military metaphors foster a general mobilization of resources (...) from multiple fields of cutting-edge research. The missile metaphor, reminiscent of Paul Ehrlich’s ‘magic bullet’, has framed the problem in simple terms: how to deliver the right dose in the right place at the right moment? Chemists, physicists and engineers who design multi-functional devices operating in vitro can think in such terms, as long as the devices are not actually operating through the messy environment of the body. A close look at what has been done and what remains to be done suggests that the metaphor of the “therapeutic missile” is neither sufficient, nor even necessary. Recent developments in nanomedicine suggest that therapeutic efficacy cannot be obtained without negotiating with the biological milieu and taking advantage of what it affords. An ‘oikological’ approach seems more appropriate, more heuristic and more promising than the popular missile. It is based on the view of organism as an oikos that has to be carefully managed. The dispositions of nanocapsules have to be coupled with the affordances of the environment. As it requires dealing with nanoparticles as relational entities (defined by their potential for interactions) rather than as stable substances (defined by intrinsic properties) this metaphor eventually might well change research priorities in nanotechnology in general.

"Public engagement in science" is one of the buzzwords that, since 2000, has been used in nanotechnology programs. To what extent does public engagement disrupt the traditional relations between science and the public? This paper briefly contrasts the traditional model of science communication - the diffusionist model - that prevailed in the twentieth century and the new model - the participatory model - that tends to prevail nowadays. Then it will try to disentangle the assumptions underlying the public dialogue initiated (...) about nanotechnology, and conclude that nanotechnology actually develops a managerial model of society.

ABSTRACTEven though Émile Meyerson is rightly seen as an opponent of Comte's positivism, analyzing passages of his works with the help of his correspondence shows the ambiguity of his relation to Comte's philosophy. Drawing on Meyerson's remarks about his relation to Comte's philosophy, this article offers a new perspective on the notion of influence, which is too often perceived as passive or unassimilated reception of a stream of ideas. I argue that Meyerson treated Comte's ideas as a sort of raw (...) matter he transformed into a finished product. (shrink)

Endogenous depression is highly correlated with low levels of serotonin in the central nervous system. Does this imply or suggest that this sort of depression just is this neurochemical deficit? Scorning such an inference, Antonio Damasio writes:If feeling happy or sad … corresponds in part to the cognitive modes under which your thoughts are operating, then the explanation also requires that the chemical acts on the circuits which generate and manipulate [such thoughts]. Which means that reducing depression to a statement (...) about the availability of serotonin or norepinephrine in general- a popular statement in the days and age of Prozac- is unacceptably rude.Damasio's thought is that depression is essentially a modification of how we perceive the world, reason about it, and make decisions about how to act in it - in other words, that it is essentially cognitive. A reduced level of serotonin might cause the said modification, but no adequate account of depression would identify the malady with its cause. A proper account would minimally need to say how cognitive processing is affected by a reduced level of serotonin. (shrink)

Many families of patients hold the view that it is their right to be present during a loved one's resuscitation, while the majority of patients also express the comfort and support they would feel by having them there. Currently, family presence is more commonly accepted in paediatric cardiopulmonary resuscitation than adult CPR. Even though many guidelines are in favour of this practice and recognise potential benefits, healthcare professionals are hesitant to support adult family presence to the extent that paediatric family (...) presence is supported. However, in this paper, we suggest that the ethical case to justify family presence during paediatric resuscitation is weaker than the justification of family presence during adult resuscitation. We go on to support this claim using three main arguments that people use in clinical ethics to justify FPDR. These include scarcity of evidence documenting disruption, psychological benefits to family members following the incident and respect for patient autonomy. We demonstrate that these arguments actually apply more strongly to A-FPDR compared with P-FPDR, thereby questioning the common attitude of healthcare professionals of allowing the latter while mostly opposing A-FPDR. Importantly, we do not wish to suggest that P-FPDR should not be allowed. Rather, we suggest that since P-FPDR is commonly allowed, so should A-FPDR. This is because the aforementioned arguments that are used to justify FPDR in general actually make a stronger case for A-FPDR. (shrink)

The temporal logic KtT4 is the modal logic obtained from the minimal temporal logic Kt by requiring the accessibility relation to be reflexive and transitive. This article aims, firstly, at providing both a model-theoretic and a proof-theoretic characterisation of a four-valued extension of the temporal logic KtT4 and, secondly, at identifying some of the most useful properties of this extension in the context of partial and paraconsistent logics.

Enseigner la philosophie, n’est peut-être pas autre chose que la tentative de ménager l’ouverture, dans une autre conscience, du plus radical des questionnements. Est-il en effet une autre discipline qui puisse prétendre à questionner aussi infatigablement? Apprendre à questionner n’est-il pas alors l’unique vocation de l’enseignement philosophique? Nous essaierons de faire un pas en direction de ces interrogations, en lisant quelques passages du cours prononcé par Martin Heidegger au semestre d’été 1935 et publié sous le titre : Introduction à la (...) métaphysique.

The Natural Contract (1990) marks the emergence of the environmental question in Serres’s work that became central in his later publications. Over the twenty years when the Anthropocene emerged as a distinct narrative entangling geological time with the history of human technology, Serres developed a rather similar “Grand Récit” embracing deep geological time, biological evolution, the process of hominization, and the future of humankind, although he did not enter into conversation with the leading figures of the interdisciplinary field of Anthropocene (...) studies. This paper seeks to characterize Serres’s position in the field of environmental philosophy as it has been reconfigured by the introduction of the concept of the Anthropocene. It first briefly surveys the personal pathway that led Serres to his diagnosis of a global climate crisis. It then compares the concepts that guided his analysis with the concepts debated in Anthropocene studies. Finally, I will suggest that the ethical measures proposed by Serres to face the crisis did not help to bring him into dialogue with the Anthropocene scholars. (shrink)

A l'instantanéité doit succéder la réflexion, à la réaction incessante le recul stratégique. La stratégie naît il y a 2500 ans, à Athènes et en Chine avec Sun Tzu et son célèbre Art de la guerre. Art militaire au départ, méthode de pensée pour l'action, elle apparaît de plus en plus indispensable dans notre monde moderne. Pourtant, le sens en a été oublié. Aujourd'hui, les décideurs - entrepreneurs, politiques, militaires - sont accaparés par le court terme et la tactique. Atteints (...) de myopie décisionnelle, ils éprouvent des difficultés grandissantes à prendre du recul. Ils ont perdu l'habitude et le goût de la stratégie, qu'ils pratiquent de moins en moins alors qu'elle seule peut apporter des réponses à la complexité du monde et à l'accélération du temps. Il faut entrer en stratégie, utiliser celle-ci pour modeler le présent et bâtir l'avenir. Le but de cet ouvrage est de faciliter cette démarche, de l'éclairer et de la démythifier. Entrer en stratégie est un guide de survie et de succès. (shrink)

L'intérêt considérable de la théorie de la culture défendue par Dan Sperber, dans son livre La contagion des idées, est d'expliciter plus fermement que de coutume les présupposés ontologiques d'une approche atomiste dans ce domaine. L'ethnographe présuppose qu'il y a dans le monde, non seulement des personnes, mais des idées. Comment les idées sont-elles dans le monde ? Le 'monisme ontologique' de Sperber consiste à refuser de multiplier les genres d'entités. Les idées sont donc, selon lui, des entités matérielles au (...) même titre que les personnes. Pourtant, le véritable problème ontologique qui se pose au sujet des idées n'est pas de décider si elles sont des objets matériels ou plutôt des objets immatériels, mais de savoir si leur mode d'être est celui des objets ou s'il est d'une autre catégorie que celle des objets.

Many philosophers and legal scholars believe that the principle of retribution can be employed as a basis for respecting the offender as a person and for imposing relatively soft sentences. This belief is inspired, at least to a certain extent, by the penal philosophy of Kant and Hegel. My aim in this article is to question this widely held belief, with my contention being that retributivists locate the basis of these normative considerations in the wrong place. It is not the (...) application of the principle of retribution that makes systems of criminal law fair and restrained, but rather the other way around: Only by restricting the application of the principle of retribution in various ways can we arrive at a system of penal law that is reasonable and just. These restrictions themselves are not retributive in nature, but are intended to keep the principle of retribution in check. To substantiate these claims, I discuss the views of an older generation of philosophers and scientists, specifically those of Sidgwick, Durkheim, Malinowski, and Piaget, and hold that these provide a fruitful basis for a better understanding of the principle of retribution. In the second part of the article, I investigate how this alternative understanding relates to the principles of proportionality and mens rea, while also making some clarifying remarks about the issue of moral luck.

I hope to demonstrate the value of a close reading Williams’s ‘Internal and External Reasons’, and to provide a theory of error regarding the substantial body of work which seeks to, in various ways, defang the essay. I do this by providing some historical context for the paper, and sketching where, historically, internalism and certain sorts of moral realism became separated. It will likely not surprise the reader when I suggest that the modern scientific worldview has an important place in (...) the discussion of the notion of external reasons. As mind, motivation, and perception have become less opaque to us, certain avenues for explaining our reasons have come closer to relying on hypotheses which may turn out to be falsifiable, and have thus been abandoned. What may come as more of a surprise is my suggestion that modern egalitarianism is an important factor as well. I suggest that impersonal reason has been used as an (implausible, but perhaps well-intentioned) alternative to the practice of some inflicting their reasons on others. (shrink)

Michel Serres est surtout connu comme philosophe de la communication. Toutefois la question du temps traverse toute son œuvre, depuis les premiers Hermès jusqu’au dernier livre. Sans recenser toutes les réflexions de Serres sur le temps, cet article montre qu’il tient une place centrale dans son anthropologie car il en fait la clé des relations entre les humains et le monde. Comment articuler notre histoire avec l’évolution de la vie, de l’univers?

ABSTRACT Medical AID organisations such as Médecins Sans Frontières receive several requests from individuals and international academic institutions to conduct research at their implementation sites in Africa. Do AID agencies have an ethical duty to comply with research requests? In this paper we respond to the views and constructed theories (albeit unfounded) of one such researcher, whose request to conduct research at one of our sites in the Democratic Republic of Congo was turned down.
