Przedmiotem pracy jest logika kombinatoryczna, gałąź logiki ufundowana przez tak ich autorów, jak Schönfinkel i Curry, której najbardziej znaczącą cechą jest tworzenie języków formalnych pozbawionych zmiennych. U pierwszym rzędzie przedstawia się pojęcia bazowe tego przedsięwzięcia, tj. teorię kombinatorów i teorię funkcjonalności. Podejmując i kontynuując rezultaty, jakie osiągnął Curry, autor poddaje analizie sposób, w jaki można otrzymać zupełny zbiór aksjomatów dla rachunku zdaniowego intuicjonistycznego, wychodząc od utworzenia zupełnego zbioru kombinatorów pierwotnych.

In this essay, we argue that there exist obvious parallels between questions that inform philosophy of chemistry and the so-called hard problem of consciousness in philosophy of mind. These include questions regarding the emergence of higher-level phenomena from lower-level physical states, the reduction of higher-level phenomena to lower-level physical states, and 'downward causation'. We, therefore, propose that the 'hard problem' of consciousness should be approached in a manner similar to that used to address parallel problems in philosophy of chemistry. Thus, (...) our contribution begins by scrutinizing the ways chemists and quantum chemists think about and use different levels of organization and chemical relations and relata and then investigates the problem of 'downward causation' as it relates to the question of emergence. We demonstrate that the science of the transformation of 'substances', namely chemistry, enables us to go beyond substantialism and to develop, instead, a non-substantialist account of levels of reality. Similarly, the 'hard problem' of consciousness will require that we transcend traditional emergentism and its substantialist conception of mind. As with chemical phenomena, mental phenomena must be examined in terms of the relationality of wholes and parts, and this will require the development of a mereology that explains how parts and wholes may co-define each other. Like the non-classical and non-transitive mereology that has been proposed for quantum chemistry, an extended mereology for philosophy of mind must be one that entangles the whole, its parts, and the environment, thus rendering 'downward causation' into a relational concept. This proposal is neither a reductionist analysis that only needs the parts to define the whole, nor a merely holistic description within which the whole is necessary to define the parts. Rather, we propose that the parts, the whole, and the environment co-define each other so that our understanding of parts, wholes, and environment as independent concepts must itself be altered.

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)

The five narratives identified by the DEEPEN-project are interpreted in terms of the ancient story of desire, evil, and the sacred, and the modern narratives of alienation and exploitation. The first three narratives of lay ethics do not take stock of what has radically changed in the modern world under the triple and joint evolution of science, religion, and philosophy. The modern narratives, in turn, are in serious need of a post-modern deconstruction. Both critiques express the limits of humanism. They (...) do not imply, however, that these narratives should not be taken seriously. In particular, the enduring presence of three ancient narratives in laypeople’s symbolic thought is highly significant in terms of the role that the logic of the sacred keeps playing in the workings of modern societies. Lay people’s implicit understanding of how modern technology tends towards catastrophe and apocalypse provides the strongest argument for taking these narratives seriously. (shrink)

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.

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)

Approximations form an essential part of scientific activity and they come in different forms: conceptual approximations (simplifications in models), mathematical approximations of various types (e.g. linear equations instead of non-linear ones, computational approximations), experimental approximations due to limitations of the instruments and so on and so forth. In this paper, we will consider one type of approximation, namely numerical approximations involved in the comparison of two results, be they experimental or theoretical. Our goal is to lay down the conceptual and (...) formal foundations of a local theory of partial truth. This is done by introducing and exploring the concept of truth space. (shrink)

In physics, one is often misled in thinking that the mathematical model of a system is part of or is that system itself. Think of expressions commonly used in physics like “point” particle, motion “on the line”, “smooth” observables, wave function, and even “going to infinity”, without forgetting perplexing phrases like “classical world” versus “quantum world”.... On the other hand, when a mathematical model becomes really inoperative in regard with correct predictions, one is forced to replace it with a new (...) one. It is precisely what happened with the emergence of quantum physics. Classical models were superseded by quantum ones through quantization prescriptions. These procedures appear often as ad hoc recipes. In the present paper, well defined quantizations, based on integral calculus and Weyl–Heisenberg symmetry, are described in simple terms through one of the most basic examples of mechanics. Starting from probability distribution on the Euclidean plane viewed as the phase space for the motion of a point particle on the line, i.e., its classical model, we will show how to build corresponding quantum model and associated probabilities or quasi-probabilities distributions. We highlight the regularizing rôle of such procedures with the familiar example of the motion of a particle with a variable mass and submitted to a step potential. (shrink)

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)

How do chemists assign numbers to chemicals properties? What do these numbers refer to? To answer these questions, we will first point out both the context-dependence of chemicals and the epistemic limitations of chemistry. We will then investigate how chemists use various procedures to stabilize measurements and how they use mixtures of samples as “references” in order to determine the amount of different chemicals in a sample. This study will enable us to query how it is possible for chemists to (...) change one factor while holding others constant at each step of the measurement procedure. This part of our work which will lead us to query the meaning of the ceteris paribus clause and the very possibility of making holistic inferences in the domain of chemistry. To conclude, we will highlight how methodological pluralism developed by chemists makes it possible for a relational type of consistency to emerge. (shrink)

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.

« Toute activité se laisse discerner et définir dans la mesure où elle prend forme, où elle inscrit sa courbe dans l’espace et le temps. La vie agit essentiellement comme créatrice de formes. La vie est forme, et la forme est le mode de la vie » (Henri Focillon). Formes de la géométrie et du cosmos, formes de la vie et de la pensée, formes architecturales, musicales et littéraires, formes fixes ou métamorphoses : le concept de forme est omniprésent dans (...) les sciences et dans les arts. C’est à une exploration de cette notion de forme que le Collège de France a consacré en octobre 2011 son colloque multidisciplinaire de rentrée : sa définition en philosophie chez Platon et Aristote, ses applications en mathématiques et en astrophysique, en chimie et en biologie, ses conséquences en psychologie et en linguistique, en anthropologie, en droit et dans les arts. Ces débats ont été aussi l’occasion de se tourner vers des pensées où elle joue un rôle particulièrement important, comme le structuralisme de Claude Lévi-Strauss ou l’histoire de l’art d’André Chastel.

During the seventeenth and eighteenth centuries, French authors did not ignore the word “éthique,” but neither did they make it play a specific role in their works like they did with “morale,” their preferred term. By contrast, English writers were more likely than their counterparts to distinguish “Ethicks” from “Morals.” Consequently, it is mainly in English-language writings that the separation of the two terms can be found. The key authors invested in refining these distinctions are Locke, Shaftesbury, Hutcheson, Hume, and (...) Bentham—the last one being the philosopher who enacted the splitting of these two terms. From their meditations gradually emerges a belief in the conditions for a common moral platform and position; in those authors’ estimation, this foundation could properly take the place of mathematical ethical inquiry. Among those exposing utilitarianism, ethics are a matter of calculation, ethical action achievable through mathematical rules. If calculation is still limited with Hutcheson, it becomes subtler still with Bentham, even if the first utilitarian author stays within the parameters of this moral philosophy. Bentham seems to be inspired by Bayesian–Pricean probability calculus, and his main and seminal ideas are developed in “The Axioms of Pathology” at the end of the “Pannomial Fragments.”. (shrink)

Vulnerability: an ethical category. Vulnerability must not be considered as an equivalent for the weakness or for the precariousness, i.e. the state in which the most resourceless people are living -with regard to power, wealth and health -; the strong are also vulnerable and they are potentially likely to be weakened. We will try to give its chance to an ethical category which, unlike person, personality, dignity, benevolence, non-malevolence, focusses on pleasures and displeasures, no more on the virtues of nursing (...) people. Moreover the category of vulnerability is quantity-sensitive. We will expose two mathematical models that highlight this last point of view. (shrink)

Building on the thought and life of Jürgen Moltmann, Hans Urs von Balthasar, Simone Weil and Teresa of Calcutta, this article demonstrates that it is possible for Christians to find joy in the context of suffering. This joy is the joy of being intimate with Christ, of experiencing Christ’s redeeming power at work effectively transforming one’s whole person. In Christ, spiritual darkness and suffering can become a most effective manifestation of the recreating communion of the human with the divine. Perfect (...) discipleship identifies with the complete offer of Jesus Christ, the suffering God, received within one’s heart, so that invincible light might be brought into the night of the world.

Jean-Pierre Faye analyse la conférence méconnue de Carl Schmitt : « Economie saine dans un Etat fort », tenue le 23 novembre 1932 devant les membres de « L’Union au Long Nom » (ou « Union pour la conservation des intérêts économiques communs en Rhénanie et Westphalie »). Schmitt y énonce la nécessité pour l’Allemagne d’un « Etat total », équivalent allemand à ses yeux de « l’État totalitaire » de l’Italie fasciste. Cette prise de parole aura un (...) effet décisif : trente-cinq représentants de la finance et de l’industrie allemandes, auditeurs de la conférence, adresseront une pétition à Hindenburg, président du Reich. Ils l’inciteront à appeler le « chef du grand mouvement » au poste de chancelier du Reich. Ce « mouvement » est le déjà criminel NSDAP : le Parti national-socialiste ouvrier allemand, le parti « nazi ». Le 30 janvier 33, Hitler sera chancelier. En neuf semaines, la conférence de Schmitt aura eu pour effet d’abattre tous les obstacles à l’avènement du Troisième Reich. La formule de « l’Etat total » a donc su transmettre aux temps et aux langages une charge à l’énergie insoupçonnée, porteuse des plus grands crimes. Ainsi est révélée la responsabilité centrale de Schmitt dans la mise en place du nazisme. Ce juriste, qui étrangement apparaît pour beaucoup aujourd’hui comme un penseur politique de référence, n’a d’abord avancé qu’une seule carte d’un jeu mortifère. Mais c’était une carte maîtresse, elle était dangereusement efficace pour faire passer le pire dans l’Histoire. Il était intéressant de lire en parallèle les « Journaux » de Schmitt et de mesurer l’attention portée par le juriste aux événements, dans les semaines qui précèdent et suivent l’arrivée d’Hitler à la chancellerie du Reich. Ce qui frappe est cependant la banalité quotidienne qui transparaît dans ces notes. Si ce n’est, peut-être, qu’un mot va lui paraître acquérir un poids nouveau : « Jude », « juif ». C’est son propre rôle, dans le nazisme, à lui Carl Schmitt, qu’il va découvrir par là... (shrink)

In an age of nationalisation of international educational policy, or vice versa, the politics and conflicts behind such policies often take centre stage to the detriment of professional expertise. In response, this article develops a nuanced critical realism to propose a practice-based development and implementation of educational policy reforms. Based on empirical reports of head teachers’ subversive practice, the article concludes by highlighting that professional expertise is a central component, dubbed ‘formless capability’, that all stakeholders use to turn policy intentions (...) into policy actions. Actuality consists of the three traditional domains of critical realism – the real, the actual and the empirical – whose importance is derived from whether it is a means to or an end in itself. It is argued here that empirical experiences of leading schools are the stage of actuality that is directly... (shrink)

Depuis la pensée des Lumières, on pouvait croire que la raison triomphante avait définitivement dévalorisé la pensée mythique, renvoyée du côté "des fables et des superstitions" : il importait donc de la considérer comme un âge révolu de la pensée humaine. Or, depuis l'époque romantique et surtout depuis les acquis des sciences humaines du 20e siècle, nous avons assisté à une redécouverte de l'importance et de la pérennité de cette pensée mythique à l'oeuvre depuis les âges les plus reculés de (...) l'humanité. C'est à cette redécouverte que Jean-Pierre Sironneau a voulu contribuer en évoquant quelques auteurs qui en avaient été les principaux artisans et en proposant, à l'occasion, ses propres interprétations.

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?"

Building on the storytelling, political storytelling, and religious storytelling literatures, I examined the role religious stories play in the formation of revolutionary convictions. This study’s primary sources of data are volumes I, II, and III of The Gospel in Solentiname, a historical record of religious discussions that took place in an isolated campesino community at a seminary-like setting under a growing national revolutionary scenario in 1970s Nicaragua. My analysis of these discussions reveals that religious discourse based on stories of prophecy, (...)

RésuméCet article explore les liens entre le recours à la véracité de Dieu et les notions de certitude «métaphysique» et «morale» chez Descartes. Pour cela, je montre le rôle qu'elles jouent dans sa preuve de l'existence du monde extérieur, sa position sur l'existence d'autres esprits et celle sur l'«animal-machine». Descartes se sert de la véracité de Dieu dans le premier cas, maispas dans le deuxième ni le troisième. Je suggere que c'est parce que faire à nouveau appel à la véracité (...) de Dieu dans le cas des autres esprits aurait mis en péril sa doctrine de l'animal-machine. Je conclus en me penchant sur des passages de Descartes qui pourraient sembler incompatibles avec l'inter prétation que je fais du rôle important quejoue la certitude morale dans sa philosophic.
