La quatrième de couverture indique : "Fruit d'une expérience intellectuelle vécue au carrefour de la science et de la philosophie, ce livre se présente comme la synthèse de préoccupations méthodologiques concernant l'étude critique des sciences. Il veut rendre manifeste le lien de nécessité et de constitution qui existe entre les sciences, l'épistémologie (comme examen critique de leurs concepts et propositions), l'histoire de leur développement, et la philosophie de la connaissance. Les six premiers chapitres portent sur des problèmes de philosophie et (...) d'histoire des sciences. Les huit suivants sont consacrés à des problèmes d'élaboration et d'interprétation de la physique contemporaine. Tout l'ouvrage est placé sous le signe de l'appropriation et de la communication des connaissances, en relation au problème de la place prise par la science dans le monde contemporain. Ce livre ne fait aucun appel à des connaissances spécialisées, et devrait être accessible à tout lecteur raisonnablement cultivé.". (shrink)

RésuméDe l'delimination des causes finales par la mathématisation de la physique à l'hypothèse de Kant‐Laplace sur la formation du système solaire, puis au développement des sciences de la vie qui déterminent un nouveau champ de rationalité, le théme de la création au 18ème siècle est parti‐culièrement apte a manifester l'évolution des rapports entre sciences, philosophie et métaphysique, jusqu'à son progressif effacement dans des philosophies aussi differentes que celles de Diderot, Hume et Kant.

Individuals across organizations and roles are increasingly seeking a meaningful and fulfilling experience in their activities. Towards that, the Bhagavad Gita advises the practice of Karma Yoga. However, the conceptualization of Karma Yoga in extant management literature is shrouded in confusion with little agreement on its dimensionalities. In this article, employing qualitative method, we offer an alternative conceptualization of the construct. Accordingly, we define Karma Yoga as a persistent positive state of mind that is characterized by absorption and service consciousness. (...) Furthermore, the findings also suggest the importance of sense control and equanimity as the necessary prerequisites for individuals to practise Karma Yoga. (shrink)

We want to consider anew the question, which is recurrent along the history of philosophy, of the relationship between rationality and mathematics, by inquiring to which extent the structuration of rationality, which ensures the unity of its function under a variety of forms, could be considered as homeomorphic with that of mathematical thought, taken in its movement and made concrete in its theories. This idea, which is as old as philosophy itself, although it has not been dominant, has still been (...) present to some degree in the thought of modern science, in Descartes as well as in Kant, Poincaré or Einstein. It has been often harshly questioned, notably in the contemporaneous period, due to the failure of the logistic programme, as well as to the variety of “empirical” knowledges, and, in a general way, to the character of knowledges that show them as transitory, evolutive and mind-built. However, the analysis of scientific thought through its inventive and creative processes leads to characterize this thought as a type of rational form whose configurations can be detailed rather precisely. In this work we shall propose, first, a quick sketch of some philosophical requirements for such a research programme, among which the need for an harmonization, and even a conciliation, between the notions of rational, of intuitive grasp and of creative thought. Then we shall examine some processes of creative scientific thought bearing on the knowledge and the understanding of the world, distinct from mathematics although keeping tight relations with them. Contemporary physical theories are privileged witnesses in this respect, for in them the rational thought of phenomena makes an intrinsic use of mathematical thought, which contributes to the structuration of the formers and to the expression of their concepts. The General Theory of Relativity and the Quantum Theory are exemplar to this, as they directly reveal what can be called the “drag of physical thought par the mathematical form”, which makes possible to overcome the limitations of the physical knowledge previously adquired. This process is tightly related to the modalities and to the stucture of the rational thought underlying it. This is what we would like to show. (shrink)

In what follows, I examine three main points which may help us to understand the deep nature of Einstein's objections to quantum mechanics. After having played a fundamental pioneer role in the birth of quantum physics, Einstein was, as is well known, far less enthusiastic about its constitution as a quantum mechanics and, since 1927, he constantly argued against the pretention of its founders and proponents to have settled a definitive and complete theory. I emphasize first the importance of the (...) philosophical climate, which was dominated by the Copenhagen orthodoxy and Bohr's idea of complementarity: What Einstein was primarily reluctant to was to accept the fundamental character of quantum mechanics as such, and to modify for it the basic principles of knowledge. I thus stress the main lines of Einstein's own programme in respect to quantum physics, which is to be considered in relation to his other contemporary attempts and achievements. Finally, I show how Einstein's arguments, when dealing with his objections, have been fruitful and some of them still worthy, with regard to recent developments concerning local nonseparability as well as concerning the problems of completeness and accomplishment of quantum theory.

Le débat sur l'interprétation de la mécanique quantique est, aujourd'hui, sensiblement différent de ce qu'il était dans la période de «fondation» de cette théorie. Cette modification tient à deux causes : l'ancrage des conceptions quantiques dans la pensée des physiciens, favorisé par l'utilisation systématique et fructueuse de la théorie quantique en physique atomique et subatomique, d'une part et, d'autre part, les développements théoriques et expérimentaux survenus au cours des vingt dernières années, qui ont amené à considérer comme des faits physiques (...) des énoncés qui paraissaient naguère relever davantage de l'interprétation, avec liberté d'options, voire de la spéculation. Quelle est la signification des énoncés et des concepts théoriques de la physique quantique ? et comment celle-ci s'est-elle modifiée ? Qu'entend-on par «interprétation» ? Telles sont les questions qui servent de guide à ce travail. Nous nous proposons de clarifier ce qui, dans les questions de signification, relève respectivement de la physique (essentiellement les contenus conceptuels et théoriques), et de perspectives philosophiques. Cette distinction est plus nette aujourd'hui qu'elle ne l'était au moment de l'établissement de la mécanique quantique, ce qui permet d'approfondir notre compréhension de chacun de ces deux aspects, qui s'enrichissent mutuellement de cette clarification. Nous nous interrogeons, pour terminer, sur ce que peut être une conception réaliste en termes d'un «monde d'objets quantiques». (shrink)

Newton's use of mathematics in mechanics was justified by him from his neo-platonician conception of the physical world that was going along with his «absolute, true and mathematical concepts» such as space, time, motion, force, etc. But physics, afterwards, although it was based on newtonian dynamics, meant differently the legitimacy of being mathematized, and this difference can be seen already in the works of eighteenth century «Geometers» such as Euler, Clairaut and d'Alembert (and later on Lagrange, Laplace and others). Despite (...) their inheritance of Newton's achievements, they understood differently the meaning and use of mathematical quantities for physics, in a way that was more neutral to metaphysics. The continental reception and assimilation of Newton's Principia had indeed occured as its budding onto Leibniz' calculus and a cartesian conception of rationality (spread in particular by the malebranchist disciples of Leibniz). This new thought of the legitimacy of mathematization is clearly at variance with Descartes' identification of physics with geometry, but it nevertheless can be traced back to Descartes' conception of magnitudes, as it was developed and analyzed from the notion of dimension in his Regulæ ad directionem ingenii (in particular, rule 14). This idea can be followed afterwards with further philosophical or mathematical specifications through authors such as Kant, Riemann and others. This inquiry into the original thought of magnitudes, and of physical magnitudes conceived through mathematization, leads us to suggest an extension of meaning for the concept of physical magnitude that puts emphasis on its relational and structural aspects rather than restraining it to a simple «numerically valued» acception. Such a broadening would have immediate implications on our comprehension of «non classical» aspects of contemporary physics in the quantum area and in dynamical systems. (shrink)

L’esigenza di conferire alla filosofia lo status di scienza per il tramite della forma sistematica è una delle caratteristiche principali dell’idealismo tedesco e, conseguentemente, una peculiarità ravvisabile nella filosofia e di Kant e di Hegel. Il presente contributo mira precisamente a comparare il sistema della ragione kantiano e hegeliano, al fine di metterne in luce gli elementi teoretici distintivi. In tal modo, sarà possibile rilevare non solo l’influsso esercitato dal filosofo di Königsberg sul pensatore di Stoccarda, ma anche l’originalità con (...) la quale il secondo assimila l’istanza sistematica del primo. In particolare, la tesi che si intende sostenere è la seguente: laddove per Kant, in ultima analisi, la dimensione morale è necessaria al fine di realizzare il sistema della ragione, per Hegel è fondamentale la dimensione teoretica, ovvero quella logica-concettuale.

Avec Albert Einstein (1879-1955), ce sont les fondements memes de notre univers qui sont bouleverses, avec les grandeurs physiques et leurs significations: l'espace et le temps sont fusionnes dans sa palette, et bientot transmutes avec la matiere elle-meme pour constituer une nouvelle geometrie du monde reel. La lumiere et les atomes se parent d'aspects quantiques qui preparent une nouvelle vision des objets materiels. Les cieux, ouverts il y a quatre siecles, se mettent a bouger, d'abord a son insu, et la (...) cosmologie, devenue science, revele que l'etoffe du monde a une histoire, qui est celle d'un deploiement continu de l'espace-temps. Cette representation mentale, qui donne prise sur le monde, s'est formee dans une tete qui pensait, comme nous, mieux que la plupart d'entre nous, comme un chercheur, un philosophe ou un artiste, un homme dans son temps. On tente ici d'en suivre la genese. (shrink)

L’insuffisance du logicisme pour la question des fondements des mathématiques nous invite à la poser sous un point de vue épistémologique, en termes de rationalité et non plus seulement de logique, et à l’étendre aux sciences formalisées portant sur la nature, comme la physique, voire à la pensée scientifique en général. On doit tenir compte, dans tous les cas, des changements qui correspondent à des constructions conceptuelles : ce sont eux qui assurent en même temps, après coup, le bien-fondé des (...) théories qui les ont préparés, en sorte que si des fondements rationnels peuvent être obtenus, ce n’est, en règle générale, que « vers l’avant ». Ces changements posent également la question de leurs conditions de possibilités. La conclusion est qu’il faut admettre, pour que ces changements, et avec eux un accroissement de la connaissance, soient possibles, des transformations corrélatives dans les formes mêmes de la rationalité, mathématique, physique et, d’une manière générale, de la rationalité scientifique.

We ponder about the kind of problems and perspectives of a “formalized epistemology”, by considering the advantages than one can get from a concern with the “formal”, with its structural orientation, that would favour comprehensive, unifying and synthetic, intelligibility. We confront this perspective with that of the changes in knowledge, considering the relation between form and meaning for knowledge contents, and examine the notion of “epistemic operation” as instrumental for creating new forms, at the theoretical and meta-theoretical levels. Actually, the (...) notions of form, of formal and of object are not independent of the problem of a subject that decides on conventions and choices. “Epistemic operations” might suggest a link with “algorithmic functions” for knowledge statements, that themselves entail the risk of reductionism in a naturalistic conception of representation. (shrink)

History of science and philosophy of science are interrelated despite the separation that predominantly occurred in xx th century, at least in cultural contexts influenced by the “anglo-saxon” philosophy. But, actually, history of science provides a rich field of philosophical problems, and this consideration may powerfully help renewing many “standard” considerations of the philosophy of science, such as, for instance, the changes and evolutions of scientific theories and representations, to take only one example, but which has been significantly related with (...) the structural or systemic character of these theories or representation, with known consequences from the “impossibility solutions” (claimed for rationality) on the debates about the social aspects of science. If, instead, history and rational concerns are to be taken together in considering, both philosophically and historically, the problem of scientific changes, then the a priori impossibility shows no more relevant, as the existence of changes is taken as factual, and we have to think deeper to understand how they occur.

Novelty and emergence in the quest for foundations. The search for firm foundations for a given knowledge, notably in the case of a formalized one, can be seen as a particular case of the search for deeper intelligibility. It generally brings to modifying the structural elements of the received knowl-edge (this having to do with questions of ontological relativity and epistemological holism), letting appear new elements of thought and of ‘reality’, emergent conceptual structures on the ground of the preceding ones. (...) We propose to show the link between the emergence of new kinds of knowledge, non thinkable previously, which enlarge the field of possible knowledge, and the effective “forward” motion of the search for foundations.

In this paper, we investigate the constitutive problems and other several aspects of what a research entitled 'formal epistemology' should be. The interest in this subject has to do with the possibility of reaching a privileged point of view or axis of research – i.e., the 'formal' one – that would allow a better grasp of the richness and variety of the facts and problems tackled by precise (local) epistemology of theories (for example, in physics). This approach is likely to (...) enable one to hold the main structural lines that organize those theories according to a more comprehensive, unifying and synthetic intelligibility. By the same token, it would eventually allow a better handling of the changes required in the organization of knowledge, putting emphasis on its main directions, drawing up a rational inventory of this knowledge, and perhaps anticipating others. At first, we deal with the 'thought of changes' that no approach of the 'form' can afford to leave aside, since the meaning of this concept is inseparable from the contents that come with constructions and modifications. We examine then the notion of 'epistemic operation' as an instrument to create new forms on the theoretical as well as on the meta-theoretical levels. In the wake of it, we analyze the characteristics of the form and of the formal, as well as their relationship with the contents of knowledge. We also take the notion of object into account, since it depends upon the decision of a subject and upon conventional choices. We finally inquire about the link between 'epistemic operations' as specified above and algorithmic functions for knowledge statements, and emphasize the risk of reductionism that might follow from a naturalistic conception of representation.

As I am not at all a specialist on Gottlob Frege’s work, my comments intended initially to be focused on an aspect that emerges in the last part of Peter Clark’s paper “Frege, neo-logicism and applied mathematics” 1, where he treats the question of “applied mathematics” — an aspect that appealed to me and that was triggered by Frege’s relationship between numbers and concepts, and reasoning. Starting with this concern, I have been led by my subject to propose some considerations (...) about foundations and rationality which will go — briefly — in two directions. The first direction is that of a distinction between logical and rational foundations, whilst the second direction is that of taking into account as a fact the historical development of mathematics among the sciences, which modifies the terms of any foundational program. In delineating these considerations, I found that what I had in mind could apply to mathematics itself as well as to “applied mathematics”, thus deviating somewhat from my first explicit intention. In conclusion I shall consider the possibility of a rational foundation programme for mathematical and physico-mathematical sciences which would take into account the changes in the scientific contents and the widenings of the forms of rationality that, in my view, make these changes possible. Such foundations for knowledge would not be any more static, but dynamical and would be possibly considered only retrospectively: they would be “forward foundations”, in a sense that will be discussed in detail elsewhere.

The problem of the nature of probability laws in physics is a central one from the epistemologic point of view : perhaps the most central one for twentieth century physics, if we consider, on the one hand, the harsh debates to which it has given rise in the recent past (left unconcluded by the protagonists and most often by their successors) and the vagueness of the answers which are generally proposed by contemporary physicists when asked about this problem ; and, (...) on the other hand, the perspectives of theoretical physics as it is developing under our eyes in the various domains - and, perhaps above all, in the "frontier" domains such as particle symmetry fields and cosmology, or, differently, dynamics of continuous media, turbulences and chaos, where probability is a - if not the - fundamental concept.

We consider the problem of therelationship between the quantum and theclassical domains from the point of view that itis possible to speak of a direct physicaldescription of quantum systems havingphysical properties. We put emphasis, inevidencing it, on the specific quantum conceptof indistinguishability of identical in aconceptual way (and not in a logical way in thevein of ``da Costa's school''). In essence, thesubsequent argumentation deals with therelationship between the classical and thequantum, with the problem of the quantum theoryof measurement. Even in (...) the absence of adefinitive response to this problem, the bestattitude for the time being, as we cannot reducethe classical and the quantum one to the other,seems to be to accept their pacific coexistence,and this is possible with the toleranceprinciple of the ``pragmatic truth'' developedfrom a logical point of view by Newton daCosta.RESUMO.

A idéia da “universalidade da ciência” é objeto, nos debates atuais, de posições muito opostas, que dependem de o ponto de vista ser o de uma “ciência ideal” ou aquele da “produção social das ciências”. No primeiro caso, a ciência é concebida como o “núcleo duro” de suas proposições e de seus resultados na época considerada, e sua suposta universalidade igno­ra os fatores que tornam relativos seus conteúdos de conhecimento e que podem ser tanto de natureza conceitual como social. Inversamente, (...) uma atenção exclusiva com os aspectos so­ciais da produção dos conhecimentos científicos ignora o caráter objetivo daqueles conteúdos de conhecimento, que tanto tratam dos objetos do pensamento, como aqueles da matemática, quanto dos fenômenos do mundo real, sejam psicobiológicos, sejam humanos e sociais. Essas duas posições extremas, caricaturais e, entretanto, freqüentemente encontradas ilustram a ausência ou o desconhecimento de análises interdisciplinares entre a filosofia, a ciência e a história da ciência. Consideraremos inicialmente alguns elementos das críticas que são feitas à universalidade da ciência, tal como a entendemos hoje, e que provêm da filosofia do conhecimento, sociologia do conhecimento, história da ciência, história e antropologia. Tentaremos, então, estabelecer o problema da universalidade da ciência como uma idéia filosófica intimamente vinculada à ciência e à filosofia, desde sua gênese. Através das diferentes etapas da história do pensamento, confrontaremos o enunciado filosófico da universalidade da ciência com a realidade histórica da produção, difusão e assimilação ou apropriação do conhecimento científico concebido segundo suas diferentes dimensões, incluindo suas aplicações e suas ligações com a técnica e a tecnologia.

Il semble que la science, au sens de l'activité des scientifiques, ne soit pas vraiment la même que celles dont s'occupent, chacune de leur coté, la réflexion philosophique et la recherche historique. Les scientifiques eux-mêmes ne sont pas toujours sensibles au lien que leur travail entretient avec la philosophie et avec l'histoire des sciences, bien qu'il concerne des significations et soit en situation d'état provisoire, entre une connaissance passée et des développements ou des interprétations futures. Cependant, les leçons de la (...) découverte et du travail scientifique, telles que ceux-ci se révèlent à travers la formulation par Einstein de la théorie de la relativité restreinte, cas étudié ici à titre d'exemple, montrent les rapports réciproques et nécessaires entre ces diverses dimensions de ce qu'on appelle la science. Cette mise en relation permet d'aborder d'une manière renouvelée certains problèmes ou certaines apories traditionnelles de la pensée de la connaissance scientifique. (shrink)
