This anthology of selections from the works of noted philosophers affords the student an immediate contact with the unique historical background of the philosophy of science. The selections, many of which have not been readily accessible, follow the development of the philosophy of science from 1786 to 1927. Each selection is preceded by a brief introduction by the editor designed to familiarize the reader with a particular philosopher and provide insights into his work. Joseph J. Kockelmans divides the selections into (...) several sections. Part 1, from 17861850, includes chapters by Immanuel Kant, on the metaphysical foundations of natural science, John Frederick William Herschel, on experience and the analysis of phenomena, William Whewell, on the nature and conditions of inductive science, and John Stuart Mill, on induction and the law of universal causation; part 2, from 18701899, includes chapters by Hermann Von Helmholtz, on the origin and significance of geometrical axioms, William Stanley Jevons, on the philosophy of inductive inference, John Bernard Stallo, on the kinetic theory of gasses and the conditions of the validity of scientific hypotheses, Ernst Mach, on the economical nature of physical inquiry, Karl Pearson, on perceptual and conceptual space, Emile Boutroux, on mechanical laws, Heinrich Hertz, on the appropriateness, correctness, and permissibility of scientific theories, and Ludwig Boltzmann, on the fundamental principles and basic equations of mechanics. The third part, covering the first decade of the twentieth century, includes chapters by Henri Jules Poincare, on science and reality, Charles Peirce, on Induction, Pierre Marie Duhem, on the laws of physics, William Ostwald, on energetism and mechanics, Emile Meyerson, on identity of thought and nature as the final goal of science, Ernst Cassirer, on functional concepts of natural science; part 4, from 19101927, includes chapters by Charles Dunbar Broad, on phenomenalism, Alfred North Whitehead, on time, space, and material, Bertrand Russell, on the world of physics and the world of sense, Norman Robert Cambbell, on the meaning of science, Moritz Schlick, on basic issues of the philosophy of natural science, and Percy Williams Bridgman, on the concepts of space, time, and causality. Philosophy of Science provides a concise single volume text to the discipline and enables students to understand and evaluate the various trends in our contemporary philosophy of science. Joseph J. Kockelmans is professor emeritus of philosophy at the Pennsylvania State Univers. (shrink)

In this 1999 book Pierre Keller examines the distinctive contributions, and the respective limitations, of Husserl's and Heidegger's approach to fundamental elements of human experience. He shows how their accounts of time, meaning, and personal identity are embedded in important alternative conceptions of how experience may be significant for us, and discusses both how these conceptions are related to each other and how they fit into a wider philosophical context. His sophisticated and accessible account of the phenomenological philosophy of (...) Husserl and the existential phenomenology of Heidegger will be of wide interest to students and specialists in these areas, while analytic philosophers of mind will be interested by the detailed parallels which he draws with a number of concerns of the analytic philosophical tradition.

During his lifetime, Henri Poincaré published three major philosophical books which achieved great success: "La science et l'hypothèse" (1902), "La valeur de la science" (1905) and "Science et méthode" (1908). After his death in 1913, a fourth volume of his philosophical works was published by his heirs as "Dernières pensées" (1913). The four books constitute the core of Poincaré's philosophic works and were given an ovation by scientific and general public. Around 1919, Gustave Le Bon wrote to Poincaré's widow. As (...) the director of the "Bibliothèque de Philosophie Scientifique at Flammarion", he asked her permission to publish a second posthumous volume. "L'Opportunisme scientifique" was intended to be the fifth and final volume of Poincaré's philosophical writings. Louis Rougier had elaborated the project, with the collaboration of Gustave Le Bon, and the approval of the philosopher Émile Boutroux and his son Pierre. Because of the reservations of the mathematician's heirs, this book was never published and Dernières pensées remained his last philosophical book. Nevertheless Poincaré's correspondence - which is kept in the Poincaré Archives at University Nancy 2 - contains a large amount of documents concerning the project, its justification and the discussions between Louis Rougier and the mathematician's heirs. The aim of this book is to restore this episode, which gives some crucial informations about editorial practices of Poincaré and about the posterity of his philosophic thinking. (shrink)

The main objective of this article is to capitalise on many years of research, and of practice, relating to the use of introspection in a research context, and thus to provide an initial outline description of introspection, while developing an introspection of introspection. After a description of the context of this research, I define the institutional conditions which would enable the renewal of introspection as a research methodology. Then I describe three aspects of introspective practice: 1) introspection as a process (...) of becoming aware, theorized through Husserl's model of consciousness modes; 2) introspection as recollection, through the model of retention and awakening in Husserl's theory of memory; 3) the use of universal descriptive categories for the description of all lived experiences, as a guide for skilled practice of introspection in research. Finally I examine the question of the validation of introspective data, suggesting a strong distinction between the ethical criterion and the epistemic criterion of truth. (shrink)

Félix Ravaisson est l’instituteur d’une nouvelle conception de la métaphysique : le spiritualisme. À travers une confrontation critique serrée avec Victor Cousin, il a réalisé une synthèse inédite de l’histoire de la philosophie antique et moderne, fondée sur l’idée de l’individualité et sur la nature surabondante de l’être. Opposée à tout phénoménisme et néocriticisme, cette nouvelle métaphysique profite de la leçon schellingienne et élève Pierre Maine de Biran au statut de refondateur de la philosophie contemporaine. De Jules Lachelier à (...) Émile Boutroux jusqu’à Henri Bergson, une tendance majeure de la philosophie française sera obligée de reconnaître sa dette envers la pensée de Ravaisson, véritable explorateur spiritualiste du « champ abandonné de la métaphysique ».

We study invariant types in NIP theories. Amongst other things: we prove a definable version of the [Formula: see text]-theorem in theories of small or medium directionality; we construct a canonical retraction from the space of [Formula: see text]-invariant types to that of [Formula: see text]-finitely satisfiable types; we show some amalgamation results for invariant types and list a number of open questions.

On parle beaucoup dans cet ouvrage de contresens, de contresens parfois createurs, qui ont fait progresser la pensee, mais aussi de contresens qui ne produisent qu'erreur et confusion, comme ceux que commettent certains tenants de la psychologie historique. On presente dans cet ouvrage plusieurs applications a des textes philosophiques d'une methode d'interpretation qui consiste a les replacer dans le contexte de l'enseignement et de la vie des ecoles philosophiques. A cote d'etudes de details consacrees a des termes philosophiques importants, on (...) trouvera dans ce volume plusieurs contributions generales, justement celebres, consacrees aux divisions de la philosophie, a l'organisation de l'enseignement dans les ecoles philosophiques, a la repartition des disciplines ou encore a la figure du sage. Les recherches de Pierre Hadot ont porte tout d'abord sur les rapports entre hellenisme et christianisme, puis sur la mystique neoplatonicienne et la philosophie de l'epoque hellenistique, et enfin sur la description du phenomene spirituel de la philosophie.

The aim of this work is to study complex ecological models exhibiting simple dynamics. We consider large scale systems which can be decomposed into weakly coupled subsystems. Perturbation Theory is used in order to get a reduced set of differential equations governing slow time varying global variables. As examples, we study the influence of the individual behaviour of animals in competition and predator-prey models. The animals are assumed to do many activities all day long such as searching for food of (...) different types. The degree of competition as well as the predation pressure are dependent upon these activities. Preys are more vulnerable when doing some activities during which they are very exposed to predators attacks rather than for others during which they are hidden. We study the effect of a change in the average individual behaviour of the animals on interspecific relationships. Computer simulations of the whole sets of equations are compared to simulations of the reduced sets of equations. (shrink)

Un aphorisme hante la philosophie occidentale. celui d'Héraclite, qui veut que " la Nature aime à se voiler ". Près de vingt-cinq siècles durant, ces quelques petits mots ont successivement signifié: que tout ce qui naît tend à mourir; que la Nature s'enveloppe dans des formes sensibles et dans des mythes; qu'elle cache en elle des vertus occultes ; mais également que l'Etre est originellement dans un état de contraction et de non-déploiement ; ou bien encore qu'il se dévoile en (...) se voilant. Ainsi cet aphorisme aura-t-il servi à expliquer les difficultés de la science de la nature, à justifier l'exégèse allégorique des textes bibliques ou à défendre le paganisme, à critiquer la violence faite à la nature par la technique et la mécanisation du monde, à expliquer enfin l'angoisse qu'inspire à l'homme moderne son être-au-monde. La même formule, illustrée par l'image du voile d'Isis et déployée par Pierre Hadot dans l'histoire de l'Occident, aura justifié, par suite de contresens créateurs, l'attitude prométhéenne - l'homme doit se rendre maître et possesseur de la Nature - comme l'attitude orphique - nul ne peut soulever le voile des mystères de la Nature, sinon le poète et l'artiste. Elle n'aura jamais cessé de tracer des perspectives nouvelles sur la réalité et de révéler les attitudes les plus diverses à l'égard de la Nature. Par là, elle confirme le propos de Nietzsche : " Une bonne sentence est trop dure à la dent du temps et tous les millénaires n'arrivent pas à la consommer, bien qu'elle serve à tout moment de nourriture.

This article reports two studies investigating the relationship between emotional feelings and respiration. In the first study, participants were asked to produce an emotion of either joy, anger, fear or sadness and to describe the breathing pattern that fit best with the generated emotion. Results revealed that breathing patterns reported during voluntary production of emotion were (a) comparable to those objectively recorded in psychophysiological experiments on emotion arousal, (b) consistently similar across individuals, and (c) clearly differentiated among joy, anger, fear, (...) and sadness. A second study used breathing instructions based on Study 1's results to investigate the impact of the manipulation of respiration on emotional feeling state. A cover story was used so that participants could not guess the actual purpose of the study. This manipulation produced significant emotional feeling states that were differentiated according to the type of breathing pattern. The implications of these findings for emotion theories based on peripheral feedback and for emotion regulation are discussed. (shrink)

Nous étudions un traité scientifique en langue arabe, achevé à Belgrade en 1779. Son titre est L’Offrande du converti pour ranimer la flamme éteinte. Il ne fut jamais imprimé, mais dix copies, d’aspect semblable à celui des manuscrits arabes traditionnels, attestent de sa circulation dans l’Empire ottoman. L’auteur, un converti à l’islam qu’on appelait Osman Efendi, y aborde la géométrie euclidienne, la géométrie d’arpentage, la dynamique galiléenne et leurs applications aux sciences militaires. Il affiche son ambition de « faire revivre (...) et renouveler » la géométrie, « science oubliée et délaissée », et révèle in fine avoir pour cela traduit des livres allemands et français. Après un essai de reconstruction de la biographie d’Osman Efendi, nous montrerons que son ouvrage est en réalité une production élaborée, dépassant largement la simple démarche de traduction. Montage soigneux de différentes sources européennes que nous identifierons, il incorpore aussi un grand nombre d’éléments directement empruntés au savoir islamique de la tradition vivante. Il est ainsi le témoin remarquable d’une tentative de constitution d’un savoir hybride euro-islamique. (shrink)

As is often the case when scientific or engineering fields emerge, new concepts are forged or old ones are adapted. When this happens, various arguments rage over what ultimately turns out to be conceptual misunderstandings. At that critical time, there is a need for an explicit reflection on the meaning of the concepts that define the field. In this position paper, we aim to provide a reasoned framework in which to think about various issues in the field of distributed cognition. (...) We argue that both relevant concepts, distribution and cognition, must be understood as continuous. As it is used in the context of distributed cognition, the concept of distribution is essentially fuzzy, and we will link it to the notion of emergence of system-level properties. The concept of cognition must also be seen as fuzzy, but for a different reason: due to its origin as an anthropocentric concept, no one has a clear handle on its meaning in a distributed setting. As the proposed framework forms a space, we then explore its geography and visit famous landmarks. (shrink)

En cet article nous montrons en premier lieu que la théorie de l'hexagone logique de Blanché n'est pas, comme il le pense, le résultat d'une réflexion philosophique, mais qu'elle relève véritablement de la logique scientifique, puisqu'elle s'insère tout naturellement dans la structure d'ensemble des liaisons uninaires de la logique trivalente des propositions. Cette démonstration nous conduit, en second lieu, à renverser le jugement défavorable que E. J. Lemmon avait porté sur la toute première ébauche de cette théorie, et ainsi à (...) déVelopper la logique modale dans le sens de Blanché plutôt que dans celui de von Wright. En troisième lieu, nous complétons l'application que fait Blanché de cette théorie de l'hexagone aux liaisons binaires de la logique bivalente des propositions, en intégrant en une seule structure tétrahexaédrique l'ensemble des seize liaisons binaires, lui-même s'étant contenté d'en grouper seulement dix en une espèce d'anneau bihexagonal.

The aim of this work is to present aggregation methods of hierarchically organized systems allowing one to replace the initial micro-system by a macro-system described by a few global variables. We also study the relations between the fast micro-dynamics and the slow macro-dynamics which can produce global properties. Emergence corresponds to a bottom-up coupling that is the result effected by a micro-level at a macro-level. As an example, we present prey-predator models with different time scales in an heterogeneous environment. A (...) fast time scale is associated to the migration process on spatial patches and a slow time scale is associated to growth and interactions between the populations. Preys must go on spatial patches where resources are located and where predators can attack them. The efficiency of the predators to catch preys is patch dependent. Perturbation methods allow us to aggregate the initial system of differential equations for the patch sub-populations into a macro-system of two differential equations governing the total population densities. We study the case of density independent and density dependent migrations. In the latter case, we show that different functional responses can emerge in the macro prey-predator model as a result of the coupling between the slow and fast systems. (shrink)

We show a transfer principle for the property that all types realised in a given elementary extension are definable. It can be written as follows: a Henselian valued field is stably embedded in an elementary extension if and only if its value group is stably embedded in its corresponding extension, its residue field is stably embedded in its corresponding extension, and the extension of valued fields satisfies a certain algebraic condition. We show for instance that all types over the Hahn (...) field $$\mathbb {R}((\mathbb {Z}))$$ are definable. Similarly, all types over the quotient field of the Witt ring $$W(\mathbb {F}_p^{\text {alg}})$$ are definable. This extends a work of Cubides and Delon and of Cubides and Ye. (shrink)

Drawing upon feminist, queer, and crip phenomenology, this essay argues that the distinct temporality of the lived, stuttering body disturbs the normalized “choreography” of communication and thereby threatens the disabled speaker's recognition as a speaking subject. Examined through the phenomenology of Maurice Merleau-Ponty and Alfred Schutz, the disabled speaking body is temporally “out of step” with the normalized bodily rhythms and pace of communicative practices in relation to both lived and objective time. Disciplined for his incalculable and therefore irrational bodily (...) choreography, the disabled speaker is foregrounded against an objective, instrumentally ordered world constituted by a disembodied and hegemonic “straight-masculine” time. Although dominant communicative choreographies may often be unlivable for disabled speakers, cripping communicative time rejects the cardinal value of futurity and invites interlocutors to gather in a noninstrumentalized and nonproductive present. This reshaping of communicative space enacts new modes of relationality and opens up an array of communicative futures suppressed or cut off by straight-masculine time. (shrink)

In order to account for how organisms can apprehend the contents of the external representations they manipulate in cognizing, the endorsement of representationalism fosters a situation of what I call cognitive overdetermination. I argue that this situation is problematic for the inclusion of these external representations in cognitive processing, as the hypothesis of extended cognition would like to have it. Since that situation arises from a commitment to representationalism (even minimal), it only affects the viability of representationalist versions of extended (...) cognition. (shrink)

Many papers have been devoted to the semantic turn Carnap took in the late 1930s after Tarski had explained to him his method for defining truth and his work on the establishment of scientific semantics. Commentators have often argued that the major turn in Carnap’s approach to languages had already been taken in the Logical Syntax of Language, but they have usually assumed that Carnap was happy to subsequently follow Tarski and adopt Tarskian semantics. In this paper, it is argued (...) that this assumption needs to be qualified and that Carnap was actually far from following Tarski when he decided to complement his syntactic method with a semantic one. Carnap and Tarski had different goals, divergent programs, and dissenting views on truth and semantics. After exploring several possible methods for the explication of logical concepts such as L-truth and L-implication, Carnap opted for definitions based on concepts he had found in Wittgenstein’s Tractatus and Waismann’s work on a logical interpretation of probability. Carnap’s reasons for taking a semantic turn are to be understood in the context of his principle of tolerance. He first hoped he could use Tarski’s technique to recover in the semantic setting the completeness result he had tried to establish in the Logical Syntax. His eventual adoption of non-Tarskian semantics can be accounted for by his program of a logical analysis of science—including empirical science—and his ambition to elaborate a unified logical framework for deductive, inductive, and modal logic, and for explicating analyticity.
