Durante cuatro siglos, cristianos (de rito romano o visigótico), musulmanes y judíos coexistieron en la ciudad de Toledo. Pero tal coexistencia, antes de terminar de manera trágica, se caracterizó por muchos matices y atravesó circunstancias diversas. Cuando los llamados mozárabes (cristianos arabizados de rito visigótico) se fundieron en la masa cristiana de rito latino y lengua hispánica, después de dominar en la ciudad durante largo tiempo, los musulmanes (mudéjares), nunca muy numerosos, alcanzaron cierto apogeo en el siglo XIV, antes de (...) quedar parcialmente marginalizados en el XV. En cuanto a los judíos, debido al papel que desempeñaban en la gestión del dinero, fueron objeto de la ira y el furor popular, sobre todo en los siglos XIV y XV, incluso después de su conversión, fingida o sincera, a la fe cristiana.

In this paper, I introduce the idea that some important parts of contemporary pure mathematics are moving away from what I call the extensional point of view. More specifically, these fields are based on criteria of identity that are not extensional. After presenting a few cases, I concentrate on homotopy theory where the situation is particularly clear. Moreover, homotopy types are arguably fundamental entities of geometry, thus of a large portion of mathematics, and potentially to all mathematics, at least according (...) to some speculative research programs.

Cet article commence par examiner tous les témoignages textuels permettant de situer des églises dans la Cordoue des VIIIe-Xe siècles et ses environs. La conclusion est que si l�on rencontre bien des lieux de culte chrétiens dans la campagne et dans la montagne (notamment les monastères de la sierra), ainsi que dans les « faubourgs » (arrabales) de la ville, il est impossible d�en situer avec certitude à l�intérieur de la madi-na, la vieille ville entourée de murailles. La seconde partie (...) du travail cherche à expliquer cette situation par l�examen des textes juridiques de l�époque, et notamment une fatwa- de début du Xe siècle, qui déclare qu�on ne peut construire, ou restaurer, des églises, qu�hors de la vue des musulmans, et à l�écart de leur « sanctuaire » (haram). La conclusion est que s�il y avait bien des églises, et des chrétiens pour les fréquenter, dans la Cordoue des VIIIe-Xe siècles, elles étaient situées dans la périphérie urbaine, leur intégration dans la ville résultant seulement de la croissance de l�agglomération à la fin du IXe et au Xe siècle, en même temps que du mouvement de conversion massive, qui ont réintroduit une mixité religieuse que les autorités islamiques prétendaient éviter.

An examination of the fundamental role cybernetics played in the birth of cognitive science and the light this sheds on current controversies. The conceptual history of cognitive science remains for the most part unwritten. In this groundbreaking book, Jean-Pierre Dupuy—one of the principal architects of cognitive science in France—provides an important chapter: the legacy of cybernetics. Contrary to popular belief, Dupuy argues, cybernetics represented not the anthropomorphization of the machine but the mechanization of the human. The founding fathers (...) of cybernetics—some of the greatest minds of the twentieth century, including John von Neumann, Norbert Wiener, Warren McCulloch, and Walter Pitts—intended to construct a materialist and mechanistic science of mental behavior that would make it possible at last to resolve the ancient philosophical problem of mind and matter. The importance of cybernetics to cognitive science, Dupuy argues, lies not in its daring conception of the human mind in terms of the functioning of a machine but in the way the strengths and weaknesses of the cybernetics approach can illuminate controversies that rage today—between cognitivists and connectionists, eliminative materialists and Wittgensteinians, functionalists and anti-reductionists. Dupuy brings to life the intellectual excitement that attended the birth of cognitive science sixty years ago. He separates the promise of cybernetic ideas from the disappointment that followed as cybernetics was rejected and consigned to intellectual oblivion. The mechanization of the mind has reemerged today as an all-encompassing paradigm in the convergence of nanotechnology, biotechnology, information technology, and cognitive science. The tensions, contradictions, paradoxes, and confusions Dupuy discerns in cybernetics offer a cautionary tale for future developments in cognitive science. (shrink)

It is commonly assumed across the language sciences that some semantic participant information is lexically encoded in the representation of verbs and some is not. In this paper, we propose that semantic obligatoriness and verb class specificity are criteria which influence whether semantic information is lexically encoded. We present a comprehensive survey of the English verbal lexicon, a sentence continuation study, and an on-line sentence processing study which confirm that both factors play a role in the lexical encoding of participant (...) information.

This paper argues for a largely unnoted distinction between relational and modal components in the lexical semantics of verbs. Wehypothesize that many verbs encode two kinds of semantic information:a relationship among participants in a situation and a subset ofcircumstances or time indices at which this relationship isevaluated. The latter we term sublexical modality.We show that linking regularities between semantic arguments andsyntactic functions provide corroborating evidence in favor of thissemantic distinction, noting cases in which the semantic groundingof linking through participant-role properties (...) apparently fails. Thissemantic grounding can be preserved, however, once we abstractaway from sublexical modality in lexical semantic representations.Semantically-based linking constraints are insensitive to the sublexicalmodality component of lexical entries and depend only on informationin a predicator's situational core.

Les grands paradigmes des sciences humaines ont été constitués, au fil de l’histoire, par l’éviction progressive de la dimension affective des objets et méthodes scientifiques. Après un long désintérêt, pour partie dû à la préoccupation de l’objectivation des phénomènes retenus par l’analyse sociologique, mais aussi à l’hypostase du social, qui a trouvé notamment chez Durkheim un accomplissement encore plus accentué que dans la plupart des conceptions holistes, la question des émotions est l’...

Jean-Pierre Dupuy, prophet of what he calls "enlightened doomsaying," has long warned that modern society is on a path to self-destruction. In this book, he pleads for a subversion of this crisis from within, arguing that it is our lopsided view of religion and reason that has set us on this course. In denial of our sacred origins and hubristically convinced of the powers of human reason, we cease to know our own limits: our disenchanted world leaves us (...) defenseless against a headlong rush into the abyss of global warming, nuclear holocaust, and the other catastrophes that loom on our horizon. Reviving the religious anthropology of Max Weber, Emile Durkheim, and Marcel Mauss and in dialogue with the work of René Girard, Dupuy shows that we must remember the world's sacredness in order to keep human violence in check. A metaphysical and theological detective, he tracks the sacred in the very fields where human reason considers itself most free from everything it judges irrational: science, technology, economics, political and strategic thought. In making such claims, The Mark of the Sacred takes on religion bashers, secularists, and fundamentalists at once. Written by one of the deepest and most versatile thinkers of our time, it militates for a world where reason is no longer an enemy of faith. (shrink)

The development of a scientific theory of mind was thus significantly delayed."--BOOK JACKET.

Transhuman, or trans-human, is the concept of an intermediary form between human and posthuman. In other words, a transhuman is a being that resembles a human in most respects but who has powers and abilities beyond those of standard humans. These abilities might include improved intelligence, awareness, strength, or durability. Transhumans sometimes appear in science-fiction as cyborgs or genetically-enhanced humans. This book will look into the question "Can machines think?" followed by "Can humans extend their lifespan and keep up with (...) machines?" In other words, do we (humans) have to modify ourselves to be bionic humans, to co-exist and make the most of machines in future? (shrink)

A formalism is introduced to represent the connective organization of an evolving neuronal network and the effects of environment on this organization by stabilization or degeneration of labile synapses associated with functioning. Learning, or the acquisition of an associative property, is related to a characteristic variability of the connective organization: the interaction of the environment with the genetic program is printed as a particular pattern of such organization through neuronal functioning. An application of the theory to the development of the (...) neuromuscular junction is proposed and the basic selective aspect of learning emphasized. (shrink)

As scholars have shown, acceptance is key to the success of Payment for Ecosystem Services (PES) scheme. While many studies adopt a static cost-benefit perspective, few address the social process leading to acceptance. Drawing on Suchman (1995), this article examines the legitimacy process underlying the acceptance of a PES in agriculture. In particular, the role of collective action in the legitimisation process is analysed, using a combination of qualitative and quantitative methods of discourse analysis. Data from an agro-environmental PES scheme (...) in France on water quality shows that acceptance depends on the normative and cognitive legitimacy that actors confer upon a public policy. (shrink)

There were three such assumptions required, one explicitly stated, and two not made explicit until Bayle. The explicit one was a certain commonly accepted double understanding of ‘destruction’: a ‘natural’ version, which made it no more than a change in a particular arrangement or ‘organization’ of particles through which an aggregate was destroyed by losing its identity, and a metaphysical version, which entailed the actual annihilation of a substance. It was assumed that the latter could be accomplished only by miraculous (...) supra-natural means available only to God. Thus, if it could be shown that the soul was ‘without parts,’ it followed that the soul was ‘naturally’ indestructible and thus immortal. Bayle summarized the Cartesian argument to immortality as follows. (shrink)

If such a thing as nanoethics is possible, it can only develop by confronting the great questions of moral philosophy, thus avoiding the pitfalls so common to regional ethics. We identify and analyze some of these pitfalls: the restriction of ethics to prudence understood as rational risk management; the reduction of ethics to cost/benefit analysis; the confusion of technique with technology and of human nature with the human condition. Once these points have been clarified, it is possible to take up (...) some weighty philosophical and metaphysical questions which are not new, but which need to be raised anew with respect to nanotechnologies: the artificialization of nature; the question of limits; the role of religion; the finiteness of the human condition as something with a beginning and an end; the relationship between knowledge and know-how; the foundations of ethics.

This paper aims to connect philosophy of chemistry, green chemistry, and moral philosophy. We first characterize chemistry by underlining how chemists: co-define chemical bodies, operations, and transformations; always refer to active and context-sensitive bodies to explain the reactions under study; and develop strategies that require and intertwine with a molecular whole, its parts, and the surroundings at the same time within an explanation. We will then point out how green chemists are transforming their current activities in order to act upon (...) the world without jeopardizing life. This part will allow us to highlight that green chemistry follows the three aforementioned characteristics while including the world as a partner, as well as biodegradability and sustainability concerns, into chemical practices. In the third part of this paper, we will show how moral philosophy can help green chemists: identify the consequentialist assumptions that ground their reasoning; and widen the scope of their ethical considerations by integrating the notion of care and that of vulnerability into their arguments. In the fourth part of the paper, we will emphasize how, in return, this investigation could help philosophers querying consequentialism as soon as the consequences of chemical activities over the world are taken into account. Furthermore, we will point out how the philosophy of chemistry provides philosophers with new arguments concerning the key debate about the ‘intrinsic value’ of life, ecosystems and the Earth, in environmental ethics. To conclude, we will highlight how mesology, that is to say the study of ‘milieux’, and the concept of ‘ecumeme’ proposed by the philosopher and geographer Augustin Berque, could become important both for green chemists and moral philosophers in order to investigate our relationships with the Earth.

Le réalisme scientifique occupe une place centrale dans le système philosophique de Mario Bunge. Au cœur de cette thèse, on trouve l’affirmation selon laquelle nous pouvons connaître le monde partiellement. Il s’ensuit que les théories scientifiques ne sont pas totalement vraies ou totalement fausses, mais plutôt partiellement vraies et partiellement fausses. Ces énoncés sur la connaissance scientifique, à première vue plausible pour quiconque est familier avec la pratique scientifique, demandent néanmoins à être clarifiés, précisés et, ultimement, à être inclus dans (...) un cadre théorique plus large et rigoureux. Depuis ses toutes premières publications sur ces questions et jusqu’à récemment, Mario Bunge n’a cessé d’interpeller les philosophes afin qu’ils développent une théorie, au sens propre du terme, de la vérité partielle afin de clarifier les enjeux épistémologiques liés au réalisme scientifique. Bunge a lui-même proposé plusieurs parties de cette théorie au fil des années, mais aucune de ces propositions ne l’a satisfait pleinement et la construction de cette théorie demeure un problème entier. Dans ce texte, nous passerons rapidement en revue certaines des approches proposées par Bunge dans ses publications et nous esquisserons certaines pistes qui devraient servir à tout le moins de desiderata pour la construction d’une théorie de la vérité partielle.

Structuralism has recently moved center stage in philosophy of mathematics. One of the issues discussed is the underlying logic of mathematical structuralism. In this paper, I want to look at the dual question, namely the underlying structures of logic. Indeed, from a mathematical structuralist standpoint, it makes perfect sense to try to identify the abstract structures underlying logic. We claim that one answer to this question is provided by categorical logic. In fact, we claim that the latter can be seen—and (...) probably should be seen—as being a structuralist approach to logic and it is from this angle that categorical logic is best understood.

This paper first queries what type of concept of emergence, if any, could be connected with the different chemical activities subsumed under the label ‘quantum chemistry’. In line with Roald Hoffmann, we propose a ‘rotation to research laboratory’ in order to point out how practitioners hold a molecular whole, its parts, and the surroundings together within their various methods when exploring chemical transformation. We then identify some requisite contents that a concept of emergence must incorporate in order to be coherent (...) from the standpoint of the scientific practices involved. In this respect, we finally propose a relational form of emergence which pays attention to the constitutive role of the modes of intervention and to the co-definition of the levels of organization. No metaphysical distinction between the higher and basic levels of organization is supposed, but only a plurality of modes of access. Moreover, these modes of access are not construed as mere ways of revealing intrinsic patterns of organization but, on the contrary, are considered to be active elements on which the constitution of those patterns depends. What is at stake in this paper is therefore not an ontological form of emergence but an agnostic one which fits what chemists do in their daily work. (shrink)

In this paper, I introduce and examine the notion of “mathematical engineering” and its impact on mathematical change. Mathematical engineering is an important part of contemporary mathematics and it roughly consists of the “construction” and development of various machines, probes and instruments used in numerous mathematical fields. As an example of such constructions, I briefly present the basic steps and properties of homology theory. I then try to show that this aspect of contemporary mathematics has important consequences on our conception (...) of mathematical knowledge, in particular mathematical growth. (shrink)
