In a 2008 paper, Walmsley argued that the explanations employed in the dynamical approach to cognitive science, as exemplified by the Haken, Kelso and Bunz model of rhythmic finger movement, and the model of infant preservative reaching developed by Esther Thelen and her colleagues, conform to Carl Hempel and Paul Oppenheim’s deductive-nomological model of explanation (also known as the covering law model). Although we think Walmsley’s approach is methodologically sound in that it starts with an analysis of scientific practice rather (...) than a general philosophical framework, we nevertheless feel that there are two problems with his paper. First, he focuses only on the deductivenomological model and so neglects the important fact that explanations are causal. Second, the explanations offered by the dynamical approach do not take the deductive-nomological format, because they do not deduce the explananda from exceptionless laws. Because of these two points, Walmsley makes the dynamical explanations in cognitive science appear problematic, while in fact they are not. (shrink)

Nous avons tous retenu la leçon de la phénoménologie l'homme n'est pas le prisonnier de ses représentations subjectives, il est directement un "être-dans-le-monde". Toutefois, tout un chacun a, à chaque instant, à choisir le mende, c'est-à-dire à se choisir et à se fonder dans le monde comme une personne unique et singulière au sein de celui-ci. Cette idée implique l'élaboration d'une discipline complémentaire à la phénoménologie, capable de cerner l'homme dans la réalité et la singularité absolues de son projet dans (...) le monde. Méthode que Sartre nomme, en modifiant la pensée de Freud, psychanalyse existentielle. Que la singularité de notre épreuve personnelle du monde soit tout à la fois ce qui nous est le plus accessible, et ce qui, pourtant, échappe constamment à notre connaissance, constitue un paradoxe, un "mystère en pleine lumière", légitimant la formation d'une psychanalyse, non moins paradoxale, de la conscience. Psychanalyse d'un genre nouveau dont Sartre esquisse dans de nombreux textes théoriques la méthode, qu'il mettra lui-même en application dans ses essais biographiques sur Baudelaire, Mallarmé, Genet et Flaubert. Percer l'identité du monde singulier d'un écrivain afin d'enrichir la compréhension de son oeuvre par celle de son élan unique dans le monde, tels sont les résultats auxquels la méthode psychanalytique sartrienne, permet d'aboutir, par-delà la seule méthode héritée de la phénoménologie. C'est à en dégager le sens et à en comprendre la fécondité aussi bien philosophique que clinique et littéraire que se consacre le présent essai. (shrink)

In this paper, I argue that explaining cognitive behavior can be achieved through what I call hybrid explanatory inferences: inferences that posit mechanisms, but also draw on observed regularities. Moreover, these inferences can be used to achieve unification, in the sense developed by Allen Newel in his work on cognitive architectures. Thus, it seems that explanatory pluralism and unification do not rule out each other in cognitive science, but rather that the former represents a way to achieve the latter.

In this paper we argue that in recent literature on mechanistic explanations, authors tend to conflate two distinct features that mechanistic models can have or fail to have: plausibility and richness. By plausibility, we mean the probability that a model is correct in the assertions it makes regarding the parts and operations of the mechanism, i.e., that the model is correct as a description of the actual mechanism. By richness, we mean the amount of detail the model gives about the (...) actual mechanism. First, we argue that there is at least a conceptual reason to keep these two features distinct, since they can vary independently from each other: models can be highly plausible while providing almost no details, while they can also be highly detailed but plainly wrong. Next, focusing on Craver's continuum of ?how-possibly,? to ?how-plausibly,? to ?how-actually? models, we argue that the conflation of plausibility and richness is harmful to the discussion because it leads to the view that both are necessary for a model to have explanatory power, while in fact, richness is only so with respect to a mechanism's activities, not its entities. This point is illustrated with two examples of functional models. (shrink)

In the literature on dynamical models in cognitive science, two issues have recently caused controversy. First, what is the relation between dynamical and mechanistic models? I will argue that dynamical models can be upgraded to be mechanistic as well, and that there are mechanistic and non-mechanistic dynamical models. Second, there is the issue of explanatory power. Since it is uncontested the mechanistic models can explain, I will focus on the non-mechanistic variety of dynamical models. It is often claimed by proponents (...) of mechanistic explanations that such models do not really explain cognitive phenomena . I will argue against this view. Although I agree that the three arguments usually offered to vindicate the explanatory power of non-mechanistic dynamical models are not enough, I consider a fourth argument, namely that such models provide understanding. The Voss strong anticipation model is used to illustrate this. (shrink)

Peu avant sa disparition, Michel Makarius (1948-2009) préparait une histoire du flou dans les arts visuels, en particulier dans la peinture et la photographie, qui prenait son point de départ à la Renaissance et se prolongeait dans le monde contemporain, celui des installations vidéo de Bill Viola et des photographies du tchèque Josef Sudek. Les trois premiers chapitres de cet ouvrage, que son auteur n'aura pas eu le temps de mener à bien, constituent un essai autonome et stimulant où (...) l'on retrouve la plume élégante de Michel Makarius. Forme souvent déconsidérée - vague ou indécise -, le flou n'est-il pas, suggère Makarius, comparable à la couleur dans le débat qui l'a longtemps opposé au dessin, soit une manière de déstabiliser notre perception pour exprimer ce qui échappe à la vision nette et à l'emprise de la rationalité? Son propos ressort en particulier de ces quelques lignes de sa "Mise au point" introductive : "Notre approche de l'art par le biais du flou a pour vocation de dépasser une problématique strictement picturale pour mettre l'accent sur le statut de la représentation. Or la vision floue nous semble placée sur une ligne de crête : D'un côté, elle avalise la représentation du visible ; d'un autre, elle décrète ce visible irreprésentable ou représentable seulement de manière approximative. Etat intermédiaire d'une réalité qui se donne et se dérobe à la fois, le flou est le lieu où s'exerce une critique de la représentation par les moyens même de la représentation. L'altération du lien visuel exprime ainsi un rapport problématique au monde. Cette faille qui ne cesse de grandir au sein de l'histoire de la peinture vise donc, au-delà du visible, le réel représenté. Telle est la fonction critique de l'art enfin retrouvée". (shrink)

Two solutions are offered to the problem of distinguishing "historical" from "functional" associations in cross-cultural surveys. The underlying logic of the mathematical model is discussed and three kinds of association distinguished: hyperdiffusional or purely "historical" association, undiffusional or purely "functional" association, and semidiffusional or mixed "historical-functional" association. Two overland diffusion arcs constitute the test sample; the relationship of social stratification to political complexity constitutes the test problem. A sifting test establishes a bimodal distribution of interval lengths between like types and (...) sifts out repetitions with a lesser interval length than the second mode. A cluster test shows that for the test problem, the "hits" cluster more than the "misses". (shrink)

Published posthumously in 1908, Ecce Homo was written in 1888 and completed just a few weeks before Nietzsche’s complete mental collapse. Its outrageously egotistical review of the philosopher’s life and works—featuring chapters called Why I Am So Wise and Why I Write Such Good Books—are redeemed from mere arrogance by masterful language and ever-relevant ideas. In addition to settling scores with his many personal and philosophical enemies, Nietzsche emphasizes the importance of questioning traditional morality, establishing autonomy, and making a commitment (...) to creativity. Essential reading for students of philosophy, this unique memoir is crucial to an understanding of Nietzsche’s other works. (shrink)

Raoul Moati intervenes in the critical debate that divided two prominent philosophers in the mid-twentieth century. In the 1950s, the British philosopher J. L. Austin advanced a theory of speech acts, or the "performative," that Jacques Derrida and John R. Searle interpreted in fundamentally different ways. Their disagreement centered on the issue of intentionality, which Derrida understood phenomenologically and Searle read pragmatically. The controversy had profound implications for the development of contemporary philosophy, which, Moati argues, can profit greatly by (...) returning to this classic debate. In this book, Moati systematically replays the historical encounter between Austin, Derrida, and Searle and the disruption that caused the lasting break between Anglo-American language philosophy and continental traditions of phenomenology and its deconstruction. The key issue, Moati argues, is not whether "intentionality," a concept derived from Husserl's phenomenology, can or cannot be linked to Austin's speech-acts as defined in his groundbreaking _How to Do Things with Words_, but rather the emphasis Searle placed on the performativity and determined pragmatic values of Austin's speech-acts, whereas Derrida insisted on the trace of writing behind every act of speech and the iterability of signs in different contexts.

In the debate about values in science, it is a time-honored tradition to distinguish between the normative question of whether non-cognitive values should play a role in science and the descriptive question of whether they in fact do so or not.1 Among philosophers of science, it is now an accepted view that the descriptive question has been settled. That is, it is no longer disputed that non-cognitive values play a role in science. Hence, all that is left to do on (...) the descriptive front is to describe these values and their roles in more detail. In the words of Longino: “We should stop asking whether social values play a role in science and ask which values and whose values play a role and how” (2004, p. .. (shrink)

In this paper, I explicate and discuss performance-similarity reasoning as a strategy for mechanism schema evaluation, understood in Lindley Darden’s sense. This strategy involves inferring hypotheses about the mechanism responsible for cognitive capacities from premises describing the performance of those capacities; performance-similarity reasoning is a type of Inference to the Best Explanation, or IBE. Two types of such inferences are distinguished: one in which the performance of two systems is compared, and another when the performance of two systems under intervention (...) is compared. Both types of inferences are illustrated with examples taken from cognitive science. I conclude that performance-similarity reasoning is an important strategy for evaluating mechanistic hypotheses.

Dans cette conférence faite à l’Association munichoise des libres-penseurs, en 1903, Raoul Francé s’emploie à démystifier le modèle des premières communautés chrétiennes. L’auteur dénonce des comportements provocants peu conformes à leur réputation de douceur et de pacifisme. Il évoque les divisions internes de ces communautés et la filiation probable entre les Esséniens et les premiers chrétiens. En s’appuyant sur des historiens, il cherche à prouver qu’on a exagéré l’importance de la persécution dont les chrétiens furent victimes sous l’empire romain. (...) La conclusion de cette conférence documentée mais polémique, est que l’histoire du christianisme est celle d’une secte ambitieuse qui a usé de stratégie non seulement pour se répandre mais aussi pour écrire sa propre légende.

Dans cet article de 1903 paru dans une revue positiviste, le naturaliste Raoul Francé (1874-1943) se réfère l’école critique d’exégèse biblique (de Strauss à Wrede) pour faire entendre la voix des libres penseurs qui remettent en question l’existence historique de Jésus. Francé considère le texte des Evangiles comme une des expressions du mouvement messianique juif, qu’il faut comprendre symboliquement et non comme un récit historique. La postface de l’éditeur de la revue, le positiviste Heinrich Molenaar, rappelle que Comte interprétait (...) déjà la figure de Jésus comme une extrapolation. (shrink)

Traite de la conception philosophique de Jacques Maritain qui a développé tout au long de sa carrière un système de pensée proche de celui de Saint Thomas d'Aquin. Cette étude s'inscrit dans la tentative de mettre en lumière les aspects fondamentaux de la quête de l'homme et de son rapport à la beauté d'après le philosophe Maritain.

Mythologies generally devote much attention to the birth of heroes and gods whose coming into the world is described as particular. Our first examples come from Greek mythology.The Furies, goddesses of vengeance, were born of the blood of Uranus who had been castrated by his son Cronos. Athena sprang, completely armed, from the head of Zeus which Prometheus had struck with an axe, an act sometimes attributed to Hephaistos. The Centaurs came from a union of Ixion with a cloud to (...) which Zeus had given the appearance of Hera with whom he was in love. Adonis came into the world from a myrrh tree (Smyrna in Greek ) which opened magically to give him birth. Ten years earlier a woman named Smyrna (myrrh) had committed incest with her father, Theios, without his realizing it; when he discovered the fact, he changed her into the tree known by that name. Bacchus was drawn out, a six months old fetus, from the body of his mother by Zeus. The body was lying in coals lit by the lightning and thunder accompanying the god's chariot as he came to visit Semele. Terrified at the sound of nature's fury, she had died of shock. Zeus sewed the fetus in his thigh and, when the time came, gave birth to Dionysius. (shrink)

A distinguished cross-cultural researcher presents a brave, heartfelt and exciting challenge to the social sciences: the creation of an international, moral order. He advocates the use of cross-cultural research to uncover a common core of values and morality. This research would then be used to ameliorate problems and guide policy in the light of those values. He shows his procedures at work in the study of ten major social and personal ills, such as mental illness, divorce, sex roles, and child (...) abuse. His research leads him inexorably to the concept of the moralnet -- the social group that provides values and support. When these are disrupted, problems are aggravated or even created.

The purpose is to analyse the concept of Intentionality in Lacan's theory, and to insist in the difference of intentional modality between "desire" and "drive". Following Zizek, Lacanian drive, as death drive, realizes the curve of the Intentionality of desire, the "goal" of drive must be thought as a topological incurvation of the "aim" of desire. In this difference between Intentionality of desire and pulsionality of drive as death drive the link to the agalmic object/goal of desire is transformed into (...) an obstacle to the fullfilment of desire. By analysing passages in Lacan seminar about Husserl's concept of Intentionality, the author wants to show how it can open a new theory of Freedom beyond Symbolico-Imaginary identifications, against the phenomenological reduction of psychical life to the only intentional perspective of desire . The author wants to show that beyond this kind of identifications and intentionality, symbolic destitution is possible from desire to drive by which the Subject of Freedom can occur. (shrink)

Among philosophers of science, there is now a widespread agreement that the DN model of explanation is poorly equipped to account for explanations in biology. Rather than identifying laws, so the consensus goes, researchers explain biological capacities by constructing a model of the underlying mechanism.We think that the dichotomy between DN explanations and mechanistic explanations is misleading. In this article, we argue that there are cases in which biological capacities are explained without constructing a model of the underlying mechanism. Although (...) these explanations do not conform to Hempel’s DN model, they do invoke more or less stable generalisations. Because they invoke generalisations and have the form of an argument, we call them inferential explanations. We support this claim by considering two examples of explanations of biological capacities: pigeon navigation and photoperiodism. Next, we will argue that these non-mechanistic explanations are crucial to biology in three ways: sometimes, they are the only thing we have, they are heuristically useful, and they provide genuine understanding and so are interesting in their own right.In the last sections we discuss the relation between types of explanations and types of experiments and situate our views within some relevant debates on explanatory power and explanatory virtues.
