Les représentants de l'École autrichienne sont ici mis sous la même bannière pour autant seulement qu'ils ont été unanimes à revendiquer pour les postulats de l'économie pure, les «lois exactes» de la théorie économique, c'est-à-dire de la théorie marginale de l'utilité, un statut particulier en ce sens qu'ils tenaient pour impossible, voire absurde ou simplement inutile de soumettre les postulats en cause à des tests empiriques. L'apriorisme dont ils se réclament, fait à juste titre la marque de commerce de l'École (...) marginaliste autrichienne; Menger en a fourni les principes, von Mises la justification, et Rothbard s'est occupé de propager la doctrine de l'autre côté de l'Atlantique.

Voici deux heureuses initiatives que nous devons à des universitaires canadiens qui n'en sont pas à leurs premiéres armes. Selon toute apparence la conception de ces anthologies ne découle pas d'une planification entre les deux auteurs. Pourtant elles se complètent remarquablement bien, et ce sur plus d'un plan.1) Leur complémentarité réside tout d'abord dans lechoix des problématiquesrespectives. Bien que les deux auteurs manifestent un même souci pour des problemès contemporains majeurs en matière d'ethique, ils ne se recoupent que quatre fois (...) sur les neuf chapitres contenus dans chaque livre, notamment à propos des questions concernant ravortement, l'euthanasie, lapeine capitale et la sexualité, encore que les textes choisis par Wesley Cragg situent l'euthanasie plutôt dans la perspective de l'infanticide, tandis que ceux retenus par Jan Narveson la discutent du point de vue de l'adulte, rapprochant l'euthanasie volontaire du suicide; la sexualité est abordée par le premier à travers les débats sur la pornographie et la censure, tandis que J.N. la situe dans l'optique de l'érotisme, de l'adultère et des conditions anthropologiques. Quant aux autres problématiques, les auteurs divergent dans leurs choix. (shrink)

Neste texto, o autor persegue dois objetivos: Examinar o de-senvolvimento da doutrina fenomenológica do conteúdo dos estados intencionais representacionais, isto é, dos estados mentais, partindo da concepção brentaniana do conteúdo intencional, examinando a contri-buição de Twardowski pela tripla distinção entre ato, conteúdo e obje-to, e apresentando as críticas que Husserl formulou a propósito dos dois predecessores, na análise do conteúdo intencional das Logische Un-tersuchungen e no contexto da doutrina da intencionalidade como corre-lação noético-noemática; Mostrar como a fenomenologia poderia intervir no (...) debate entre internalismo e externalismo, mediante uma sé-rie de argumentos anti-externalistas, a partir do conteúdo dos estados intencionais.

Un grand nombre de problèmes dont traite aujourd'hui la théorie de la décision reposent sur des problématiques qui appartiennent à des approches philosophiques, méthodologiques et théoriques fort différentes et dont l'auteur deChoix rationnel et vie publiquedéplore à juste titre l'absence d'unité intrinsèque. En effet, les racines de la théorie contemporaine du choix rationnel ont des ramifications dans trois traditions philosophiques qui ont été maintenues sans entretenir de contacts: théories philosophiques de l'action d'Aristote à Hume, à Kant et à la philosophie (...) analytique de l'action de Davidson; la théorie du conflit de Hobbes à David Gauthier; la théorie de la justice (d'inspiration utilitariste qui a profondément marqué la pensée économique du XXesiècle). Ces branches ont entretenu des interactions sporadiques, mais ces relations n'ont jamais été exploitées systématiquement. Le travail que présente l'auteur est une première tentative dans cette direction, du moins en langue française. (shrink)

La théorie du choix social qui s'est développée durant les dernières décennies, notamment dans la ligne des travaux d'Arrow et de Sen , ne s'est pas seulement soldée par une série de résultats négatifs exprimés dans les théorèmes d'impossibilité d'Arrow, de Sen et d'autres; ses notions centrales ont aussi été utilisées de manière fort variée au point que cette théorie souffre aujourd'hui d'un déficit important qui se traduit par de multiples indéterminations conceptuelles.

L'interet de Habermas pour lamodernitédont traite son dernier livre, le tourne vers les travaux de Foucault. Celui-ci aurait mis en évidence, dès l'Histoire de la folie, ce qu'il y a de nouveau sous le ciel de la rationalité moderne. Dans plusieurs chapitres consacrés à Foucault, Habermas esquisse une critique qui s'inspire substantiellement des travaux de Fink-Eitel, Fraser, Honegger, Rippel et Münkler, Dreyfus et Rabinow et de Honneth. Cette critique est radicale et prend pour cible la présumée théorie du pouvoir de (...) Foucault, les impasses où conduisent les instructions méthodologiques qu'il entend observer pour reconstruire l'histoire recente des sciences humaines, ainsi que les thèses au sujet du rapport entre les pratiques discursives et les pratiques non discursives, plus exactement les dispositifs de pouvoir dans lesquels les sciences humaines se trouvent intégrées. Bien que Foucault n'ait jamais développé une telle théorie du pouvoir et qu'il dise n'avoir jamais voulu l'élaborer, on doit constater avec Habermas que le thème du pouvoir est pourtant omniprésent, et que le concept de pouvoir doit ëtre considéré comme une notion centrale dans son oeuvre.

La philosophie analytique de l'action se réclame du langage ordinaire de l'action comme une des sources de ses data philosophiques. Elle se propose d'en examiner le fonctionnement, d'en extraire les concepts clés, de caractériser les formes de propositions dans lesquelles s'expriment nos actions et notre façon spontanée de les comprendre, d'examiner l'articulation propre aux stratégies d'action et au discours qui les justifie, et de faire des « proposals » pour la construction d'une théorie de l'action. En somme, il s'agit d'ériger (...) le langage ordinaire en instance de contrôle aussi bien sur le plan du traitement de problèmes philosophiques que sur celui de la construction de méta-théories des sciences de l'homme. Ce travail sur le langage de l'action peut revêtir plusieurs fonctions: fonction de clarification ou de détection de confusions, fonction thérapeutique pour guérir le langage de maladies philosophiques, c'est-à-dire des pseudo-problèmes, fonction heuristique pour prescrire une diète appropriée au traitement des perplexités philosophiques qui surgissent « quand le langage tourne à vide, non quand il travaille », pour employer le mot de Wittgenstein.

Following Kuhn's main thesis according to which theory revision and acceptance is always paradigm relative, I propose to outline some possible consequences of such a view. First, asking the question in what sense Bayesian decision theory could serve as the appropriate (normative) theory of rationality examined from the point of view of the epistemology of theory acceptance, I argue that Bayesianism leads to a narrow conception of theory acceptance. Second, regarding the different types of theory revision, i.e. expansion, contraction, replacement (...) and residuals shifts, I extract from Kuhn's view a series of indications showing that theory replacement cannot be rationalized within the framework of Bayesian decision theory, not even within a more sophisticated version of that model. Third, and finally, I will point to the need for a more comprehensive model of rationality than the Bayesian expected utility maximization model, the need for a model which could better deal with the different aspects of theory replacement. I will show that Kuhn's distinction between normal and revolutionary science gives us several hints for a more adequate theory of rationality in science. I will also show that Kuhn is not in a position to fully articulate his main ideas and that he well be confronted with a serious problem concerning collective choice of a paradigm. (shrink)

L'histoire de la philosophie est marquée par de nombreuses tentatives pour soustraire la morale aux préceptes dictés par une croyance religieuse aveugle, l'arracher aux limbes des émotions, des intérêts égoïstes, des «nobles» sentiments ou des passions troubles de la volonté de puissance, la sortir du terrain où se disputent âprement les évidences intuitives, l'inscrire dans le règne de la raison. Il s'agit de tentatives en vue de fonder les obligations morales, l'éthique tout court, de manière rationnelle. Or, ces démarches peuvent (...) emprunter des chemins variables selon que la rationalité de l'action se trouve conceptualisée dans la perspective des intérêts et préférences raisonnés, ou qu'elle se comprend à partir de la raison pratique dans sa pureté.

Critics of the target article objected to our account of art appreciators' sensitivity to art-historical contexts and functions, the relations among the modes of artistic appreciation, and the weaknesses of aesthetic science. To rebut these objections and justify our program, we argue that the current neglect of sensitivity to art-historical contexts persists as a result of a pervasive aesthetic–artistic confound; we further specify our claim that basic exposure and the design stance are necessary conditions of artistic understanding; and we explain (...) why many experimental studies do not belong to a psycho-historical science of art.

To introduce the issue of the tracking and identification of human agents, I examine the ability of an agent to track a human person and distinguish this target from other individuals: The ability to perform person identification. First, I discuss influential mechanistic models of the perceptual recognition of human faces and people. Such models propose detailed hypotheses about the parts and activities of the mental mechanisms that control the perceptual recognition of persons. However, models based on perceptual recognition are incomplete (...) theories of person identification because they do not explain several identification behaviors that are fundamental to human social interactions. Furthermore, recognition-based models tend to appeal to the controversial concept of the “identity” of a person without explaining what determines personal identity and persistence. To overcome these limitations, I propose to integrate the face-recognition program into a broader causal-historical theory of identification. The causal-historical theory of identification complements models focused on perceptual recognition because it can account for the types of non-perceptual identification overlooked by the face-recognition program. Moreover, it can decompose the identification behaviors into tracking processes that succeed or fail to be sensitive to causal characteristics of a target. I illustrate these advantages with a discussion of the difference between the tracking of a person understood as either a causally continuous biological organism or a psychologically continuous mind. Finally, I argue that the causal-historical theory provides a theoretical framework for investigating the tracking of relations between a target and its contextual and historical attributes, such as a target's possessions.

Research seeking a scientific foundation for the theory of art appreciation has raised controversies at the intersection of the social and cognitive sciences. Though equally relevant to a scientific inquiry into art appreciation, psychological and historical approaches to art developed independently and lack a common core of theoretical principles. Historicists argue that psychological and brain sciences ignore the fact that artworks are artifacts produced and appreciated in the context of unique historical situations and artistic intentions. After revealing flaws in the (...) psychological approach, we introduce a psycho-historical framework for the science of art appreciation. This framework demonstrates that a science of art appreciation must investigate how appreciators process causal and historical information to classify and explain their psychological responses to art. Expanding on research about the cognition of artifacts, we identify three modes of appreciation: basic exposure to an artwork, the artistic design stance, and artistic understanding. The artistic design stance, a requisite for artistic understanding, is an attitude whereby appreciators develop their sensitivity to art-historical contexts by means of inquiries into the making, authorship, and functions of artworks. We defend and illustrate the psycho-historical framework with an analysis of existing studies on art appreciation in empirical aesthetics. Finally, we argue that the fluency theory of aesthetic pleasure can be amended to meet the requirements of the framework. We conclude that scientists can tackle fundamental questions about the nature and appreciation of art within the psycho-historical framework. (shrink)

Many scholars view artworks as the products of cultural history and arbitrary institutional conventions. Others construe art as the result of psychological mechanisms internal to the organism. These historical and psychological approaches are often viewed as foes rather than friends. Is it possible to combine these two approaches in a unified analysis of the perception and consciousness of artworks? I defend a positive answer to this question and propose a psycho-historical theory, which argues that artworks are historical and material artefacts (...) designed to prompt mental activities and elicit the conscious experience of aesthetic worlds. My argument suggests that the material components of artworks--termed their `material substrata'--are crucial mediators between historical contexts and the mental activities elicited by the perception of artworks.

This commentary suggests that understanding the “Folk Psychology of Souls” requires studying a problem articulating ontology with psychology: How do human beings, both as perceivers and thinkers, track and refer to (1) living and dead intentional agents and (2) supernatural agents? The problem is discussed in the light of the principle of the ontological commitment in agent tracking.

To analyze the relations between art and science, philosophers and historians have developed different lines of inquiry. A first type of inquiry considers how artistic and scientific practices have interacted over human history. Another project aims to determine the contributions that scientific research can make to our understanding of art, including the contributions that cognitive science can make to philosophical questions about the nature of art. We rely on contributions made to these projects in order to demonstrate that art and (...) science are codependent phenomena. Specifically, we explore the codependence of art and science in the context of a historical analysis of their interactions and in the context of contemporary debates on the cognitive science of art.

Has the time come to put to bed the concept of a harm threshold when discussing the ethics of reproductive decision making and the legal limits that should be placed upon it?

Last year at VSS, Bullot, Droulez & Pylyshyn reported studies using a Modified Traveling Salesman Paradigm in which a virtual vehicle had to visit up to 10 targets once and only once, and in which the invisible targets were identified only by line segments pointing from the vehicle toward each target. We hypothesized that subjects used two distinct strategies: A “location-based strategy”, which kept track of where targets were located in screen coordinates, and a “segment-based strategy” that kept track of (...) which segments corresponded to visited targets. We report new studies that further explore these two strategies. Subjects passively observed a computer-controlled virtual vehicle that visited a number of targets. Two forms of display were used: an “Allocentric” display, in which the vehicle moved and the targets remained fixed in screen coordinates, and an “Egocentric” display, in which the vehicle's position on the screen remained fixed while the targets moved -- as if the environment were being viewed by an observer on the vehicle. At the end of each trial, the directional segments were extended to the edge of the screen and subjects were asked to perform two tasks by referring to these segments. In the “status task” observers had to indicate for each segment whether the corresponding target had been visited or not. In the “locating task” they had to locate each target along its directional segment. Performance on these two tasks measures the use of the two hypothesized strategies. Results showed that observers do well on the status task with 4 or 6 targets in both display conditions, but do poorly on the locating task, especially in the egocentric condition when there are more targets. These results are consistent with the hypothesis that in the egocentric condition the MTSP task is carried out primarily by segment-tracking, which can be viewed as a deictic strategy. (shrink)

Object identification via a perceptual-demonstrative mode of presentation has been studied in cognitive science as a particularly direct and context-dependent means of identifying objects. Several recent works in cognitive science have attempted to clarify the relation between attention, demonstrative identification and context exploration. Assuming a distinction between ‘ demonstrative reference' and ‘perceptual-demonstrative identification', this article aims at specifying the role of attention in the latter and in the linking of conceptual and non conceptual contents while exploring a spatial context. First, (...) the analysis presents an argument to the effect that selection by overt and covert attention is needed for perceptual-demonstrative identification since overt/covert selective attention is required for the situated cognitive access to the target object. Second, it describes a hypothesis that makes explicit some of the roles of attention: the hypothesis of identification by epistemic attention via the control of perceptual routines. (shrink)

This study investigates a new experimental paradigm called the Modified Traveling Salesman Problem. This task requires subjects to visit once and only once n invisible targets in a 2D display, using a virtual vehicle controlled by the subject. Subjects can only see the directions of the targets from the current location of the vehicle, displayed by a set of oriented segments that can be viewed inside a circular window surrounding the vehicle. Two conditions were compared. In the “allocentric” condition, subjects (...) see the vehicle move across the screen and change orientation under their command. The “egocentric” condition is similar except for how the information is provided: the position and orientation of the vehicle icon remains fixed at the center of the screen and only target directions, as indicated by the oriented segments, change as the subject “moves” the vehicle. The unexpected finding was that this task can be performed, in either condition, for up to 10 targets. We consider two possible strategies that might be used, a location-based strategy and a segment strategy. The location-based strategy relies on spatial memory and attempts to infer the locations of all the targets. The segment strategy is more local and focuses on the directional segments themselves, keeping track of the ones that represent already-visited targets. A number of observations suggest that the segment strategy was used, at least for larger numbers of targets. According to our hypothesis, keeping track of the segments requires one to use indexical reference for associating the segments with their status in the task - given by current status predicates Visited or Not-visited -, perhaps using visual indexes, deictic pointers, or object files.

This article puts forward an hypothesis on the aesthetic use of attention. Some artistic situations favour such a use of attention and may contribute to the conscious access to cognitive and emotional contents and effects, as well as to their discussion in the public sphere.

This text aims at presenting a general characterization of the act of perceiving a particular object, in a framework in which perception is conceived of as a mental and cognitive faculty having specific functions that other faculties such as imagination and memory do not possess. I introduce the problem of determining the occurrence of singular perception of a physical object, as opposed to the occurrence of other mental states or attitudes. I propose that clarifying this occurrence problem requires making explicit (...) the conditions of perceptual competence/faculty so as to explain the occurrence of each perceptual performance on the basis of the use of this competence. I argue then for a direct relational model according to which the singular perception of an object depends on a competence of connecting the perceiver directly with each target object. This model is compatible with a disjunctive approach to perception according to which each particular experience of an object corresponds either to a direct perceptual relation with this object or to the illusion of having the experience of this object. The arguments in favour of this relational model rest on the idea that the faculty of perception grounds the capacity to demonstratively identify physical objects. (shrink)

To explain agent-identification behaviours, universalist theories in the biological and cognitive sciences have posited mental mechanisms thought to be universal to all humans, such as agent detection and face recognition mechanisms. These universalist theories have paid little attention to how particular sociocultural or historical contexts interact with the psychobiological processes of agent-identification. In contrast to universalist theories, contextualist theories appeal to particular historical and sociocultural contexts for explaining agent-identification. Contextualist theories tend to adopt idiographic methods aimed at recording the heterogeneity (...) of human behaviours across history, space, and cultures. Defenders of the universalist approach tend to criticise idiographic methods because such methods can lead to relativism or may lack generality. To overcome explanatory limitations of proposals that adopt either universalist or contextualist approaches in isolation, I propose a philosophical model that integrates contributions from both traditions: the psycho-historical theory of agent-identification. This theory investigates how the tracking processes that humans use for identifying agents interact with the unique socio-historical contexts that support agent-identification practices. In integrating hypotheses about the history of agents with psychological and epistemological principles regarding agent-identification, the theory can generate novel hypotheses regarding the distinction between recognition-based, heuristic-based, and explanation-based agent-identification.

In this article, I identify “spontaneity” as a significant but poorly-analyzed term in social theory and description through an overview of tensions between varying technical accounts of spontaneity in research literature. In contrast to conceptually-slippery “realist” accounts of spontaneity, I argue for viewing spontaneity ethnomethodologically, i.e., as a contextually-emergent social practice. I suggest two directions for future applications of this approach: first, an ethnomethodological approach to rhetorical analysis of unanalyzed use of the term “spontaneity” in research literature, and second, observational (...) studies of improvisational theatre, a social practice in which orientation toward the production of spontaneity by participants is criterial to the identity of the practice.
