There is growing interest in the effect of sound on visual motion perception. One model involves the illusion created when two identical objects moving towards each other on a two-dimensional visual display can be seen to either bounce off or stream through each other. Previous studies show that the large bias normally seen toward the streaming percept can be modulated by the presentation of an auditory event at the moment of coincidence. However, no reports to date provide sufficient evidence to (...) indicate whether the sound bounce-inducing effect is due to a perceptual binding process or merely to an explicit inference resulting from the transient auditory stimulus resembling a physical collision of two objects. In the present study, we used a novel experimental design in which a subliminal sound was presented either 150 ms before, at, or 150 ms after the moment of coincidence of two disks moving towards each other. The results showed that there was an increased perception of bouncing when the subliminal sound was presented at or 150 ms after the moment of coincidence compared to when no sound was presented. These findings provide the first empirical demonstration that activation of the human auditory system without reaching consciousness affects the perception of an ambiguous visual motion display.

More or less explicitly inspired by the Aristotelian classification of arguments, a wide tradition makes a sharp distinction between argument and proof. Ch. Perelman and R. Johnson, among others, share this view based on the principle that the conclusion of an argument is uncertain while the conclusion of a proof is certain. Producing proof is certainly a major part of mathematical activity. Yet, in practice, mathematicians, expert or beginner, argue about mathematical proofs. This happens during the search for a proof, (...) then when the proof is presented and discussed by experts, and finally when it is taught or used in didactical contexts. (shrink)

Granting that arguments and explanations that answer a why-question are the products of two species of the activity of reason-giving, do they make an exclusive and exhaustive classification? The orthodox distinction between argument and explanation already faces some tough cases, which are discussed. This paper shows that most of the criteria used to distinguish argument and explanation on the basis of the status of their conclusions cause tough cases to proliferate unless a debatable decision is made. This suggests that the (...) orthodox distinction should be improved. (shrink)

L'évêque anglican Joseph Butler proclama, au XVIIIe siècle, que " la probabilité est le guide même de la vie ". Aujourd'hui, probabilités et statistiques ont envahi quasiment tous les domaines de nos vies privées et publiques. Les politiques gardent les yeux rivés sur les sondages, les organismes de retraite nous annoncent des années noires au vu des courbes démographiques, et dans l'intimité de nos salles de bains, perchés sur la balance, nous nous demandons si notre poids est conforme à la (...) moyenne. Dans le domaine scientifique, l'usage de la probabilité semble avoir détrôné un goût de la certitude plus cartésien : l'irruption de la mécanique quantique et de sa fameuse fonction d'onde a fait couler des fleuves d'encre philosophique. Mais une querelle d'interprétation continue à opposer deux conceptions irréductibles : selon l'une, la probabilité est une affaire foncièrement subjective qui relève essentiellement de l'état des croyances de chacun ; selon l'autre, elle est avant tout une question objective relative à la fréquence d'apparition de phénomènes dits aléatoires. De ce concept essentiel et délicat, Ian Hacking tente ici l'archéologie. Comment la probabilité a-t-elle pu devenir aussi envahissante, en politique comme en science, et qu'a-t-elle à voir avec l'opinion? Comment une notion apparemment aussi fugace est-elle devenue l'objet d'un calcul? Quels défis lance-t-elle au raisonnement et à la logique? Dans cette quête aux allures de roman policier, Pascal, Leibniz ou Huygens côtoient des politiques mettant en place un système de rentes à vie, des amateurs tentant de déceler dans des épidémies un ordre sous-jacent, des joueurs impénitents et des inconditionnels de la loterie.

This paper provides methodological tools and considers the reasons why it is difficult to address the controversial question, “Are fallacies frequent?” After preliminary remarks on the need to clarify the meaning of both ‘fallacy’ and ‘frequency,’ this paper shows that the emphasis on whether fallacies occur frequently is recent and bound to contemporary definitions that make it a necessary condition. Then, it discusses three different, debated empirical approaches that are intended to support the claim that fallacies are frequent. All of (...) them raise doubts or objections or are even controversial from a methodological point of view. Ultimately, more empirical research is needed to answer this question. (shrink)

The paper discusses the place and the status of fallacies in Arnauld and Nicole’s Port-Royal Logic, which seems to be the first book to introduce a radical change from the traditional Aristotelian account of fallacies. The most striking innovation is not in the definition of a fallacy but in the publication of a new list of fallacies, dropping some Aristotelian ones and adding more than ten new ones. The first part of the paper deals with the context of the book’s (...) publication. We then show the influence of Cartesian and Augustinian/Pascalian philosophy on the whole book, especially their common critical views about logic, dialectic and their traditional academic teaching. The third part of the paper discusses the two chapters on fallacies. It focuses on their place in the book and their relation with its general orientation, before turning to their content, closely connected with some major concerns of the time. (shrink)

Inferential communities are communities using specific substantial argumentative schemes. The religious or scientific communities are examples. I discuss the status of the mathematical community as it appears through the position held by the French mathematician Henri Poincaré during his famous ar-guments with Russell, Hilbert, Peano and Cantor. The paper focuses on the status of complete induction and how logic and psychology shape the community of mathematicians and the teaching of mathematics.

This paper is a survey of Father Mersenne’s views about the classification of sciences, its reasons and its practical consequences. Some emphasis is put on the interconnection between Mersenne’s two majors ideas about the practice of science : scientific research is an activity mostly devoted to religious apology and to the edification of the people. This religious concern allows him to resist two of the most influential philosophical streams of his time, scepticism and alchemy, which provide some favorite opponents to (...) his works. We also show how an analogical kinship based on theological considerations and on the classification of sciences gives ground to the same kind of arguments shaping his views about arithmetic, language, and music. Finally, we focus on the connection between Mersenne’s theses, especially about the nature and virtue of language and sound, and a more general discussion of the scientific status of music and language in the context of the blooming of academies.

Les Vers de la Doctrine, translated from Pali by André Chedel. Dervy-Livres, Paris 1976. 104pp. Fes. 18.

Au moment où des tentatives parcellaires se font jour au sein de l'intelligentsia occidentale pour débusquer les traces du totalitarisme sous toutes ses formes, on ne se doute peut-être pas qu'un philosophe français - l'auteur de L'Essence de la Manifestation-élabore depuis vingt ans déjà une philosophie de l'individu et qu'il apporte les principes d'une critique rigoureuse de l'entité collective. En consacrant un ouvrage à la philosophie de Michel Henry, G. Dufour-Kowalska a songé à ce qui sans doute manque (...) le plus à la pensée contemporaine: un enracinement métaphysique de la critique des idéologies et une philosophie de la réalité humaine que l'essor de ces idéologies a fini par oblitérer. Une philosophie de la vie et de la praxis est la "répétition" au sens heidéggerien, mais aussi la découverte éblouie d'une philosophie réaliste, sans doute unique en notre temps, d'une ontologie de l'homme, pour laquelle la Pensée, le Savoir, le Monde des Idées, sont toujours l'apparence et qui voudrait saisir derrière ces expressions relatives et précaires de la vie humaine la force tranquille d'un absolu qui est cette vie elle-même. La contribution propre de, la pensée de M. Henry à la philosophie en général, écrit l'auteur dans sa conclusion, réside dans ce retour qu'elle accomplit au pays déserté de la métaphysique, dans cette obstination qu'elle manifeste pour arracher à l'oubli et à l'indifférence, comme le faisaient inlassablement les Anciens, le domaine de l'invisible, la face cachée du monde.

This work consists in a bibliography of plotinian studies published between 1950-2000. All the major existing bibliographical indexes have been put to contribution to offer a comprehensive list of more than 1500 entries, collected in a single and easy-to-use book.

This book addresses central issues in the philosophy and metaphysics of science, namely the nature of scientific theories, their partial truth, and the necessity of scientific laws within a moderate realist and empiricist perspective. Accordingly, good arguments in favour of the existence of unobservable entities postulated by our best theories, such as electrons, must be inductively grounded on perceptual experience and not their explanatory power as most defenders of scientific realism claim. Similarly, belief in the reality of dispositions such as (...) causal powers which ground the natural necessity of scientific laws must be based on experience. Hence, this book offers a synthetic presentation of an original metaphysics of science, namely a metaphysics of properties, both categorical and dispositional, while at the same time opposing strong versions of necessitarism according to which laws are true in all possible worlds. The main theses and arguments are clearly presented in a non-technical way. Thus, on top of being of interest to the specialists of the topics discussed, it is also useful as a textbook in courses for third year and more advanced university students. (shrink)

L'histoire de la philosophie a toujours vu en Plotin un metaphysicien. Porphyre ne dit-il pas de son maitre qu'il connaissait parfaitement la geometrie, l'arithmetique, la mecanique, l'optique et la musique, mais qu'il n'etait pas enclin a approfondir davantage ces disciplines? Ce peu de gout pour les mathematiques et la physique n'a pourtant pas empeche Plotin de rediger quelques traites exclusivement connsacres a des questions de physique et de cosmologie, traites qui furent les grands oublies des etudes neioplatoniciennes. Parmi ceux-ci, le (...) traite Sur le ciel est d'une importance capitale aussi bien en raison du sujet qu'il aborde que du debat philosophique qu'il engage avec la tradition. La vision plotinienne du monde et du ciel doit en effet trouver sa place au sein des theories cosmologiques dominantes de son epoque: celles transmises par le Timee de Platon, le De Caelo d'Aristote et la vision stoicienne de l'univers. Il va sans dire que Plotin se veut un exegete des doctrines platoniciennes, mais le present traite montre peut-etre plus que tout autre la difficile cohabitation de l'independance d'esprit et de la fidelite aux textes du maitre. Ce qui se presente comme une exegese du Timee devient en fait une trahison des enseignements qui y sont contenus. Le traite II, 1 [40] fut le theatre d'une rebellion, celle d'un interprete platonicinen qui tente de lire dans le Timee une theorie qui ne s'y trouve pas. (shrink)

Ciencia y lógica de mundos posibles indaga en un aspecto negativo de la visión positivista de la historia del pensamiento. Según esta interpretación, determinante dentro del pensamiento contemporáneo, existe una oposición irredimible entre la metodología del conocimiento científico y la metafísica. El estudio de los supuestos ontológicos de la epistemología aristotélica y de la nueva metodología galileana evidencia, sin embargo, que históricamente la ciencia moderna no nace en oposición a la metafísica, sino que surge a partir de una concepción metafísica (...) determinada. Resulta imposible comprender a fondo el fenómeno de la revolución galileana sin tener en cuenta los aportes lógicos de pensadores medievales que tuvieron una actitud crítica frente a las implicaciones ontológicas de la epistemología aristotélica. Con el advenimiento del idealismo trascendental - a diferencia de Descartes, Leibniz o Newton - la filosofía se separa de la ciencia experimental. Esto se debe a que con Kant la filosofía se aleja de la postura filosófica de los origenes de la ciencia moderna, y retorna a una concepción de la naturaleza en cierto modo similar a la aristotélica. Así mismo, la interpretación propuesta en el manifiesto del Círculo de Viena con respecto a algunas de las revoluciones científicas de los siglos XIX y XX, supone que la ciencia moderna se ha desarrollado en la dirección señalada por la concepción metafísica del mundo que se encuentra en el origen de la revolución galileana.

La contribution de Michel Troper à la théorie générale du droit et à la théorie constitutionnelle est aujourd'hui reconnue et célébrée un peu partout dans le monde. Un talent d'architecte se tient à l'origine de cette audience rarement égalée dans la sphère francophone : celui qu'il faut pour accommoder toutes les exigences, quel que soit l'ordre de valeur dans lequel on les trouve : originalité, rigueur, souci de la fonction, esthétisme, solidité, adaptation, intelligence, inquiétude, esprit critique, renoncement, réalisme... A (...) ces mérites, on ajoutera une curiosité insatiable, un goût prononcé pour l'échange et le débat, un refus distingué de l'académisme, un sens exigeant de l'amitié et une méfiance profônde pour les adjectifs... C'est cet édifice de qualités que les élèves, collègues et amis de Michel Troper sont heureux de célébrer en lui offrant ces Mélanges. (shrink)

This paper examines two influential theoretical frameworks, set forth by Russell Barkley (1997) and Thomas Brown (2005), and argues that important headway in understanding attention deficit hyperactivity disorder can be made if we acknowledge the way in which human cognition and action are essentially embodied and enactive. The way in which we actively make sense of the world is structured by our bodily dynamics and our sensorimotor engagement with our surroundings. These bodily dynamics are linked to an individual's concerns and (...) felt needs, so that what she attends to in perception, decision-making, and action is partially constituted by her cares and concerns. What I call ?affective framing? engages the whole living body, and ordinarily contributes to attentional focusing, working memory, goal-formulation, and action-monitoring. However, due to affective framing deficits, subjects with ADHD find it difficult to focus their attention, kindle their motivation, and systematically simplify cognitive procedures according to considerations of relevance, salience, and context. Thus, what is impaired in ADHD is not simply a set of executive brain functions, but rather a range of bodily dynamics through which subjects engage with their world. For this reason, intensive behavioral intervention that engages the whole living body may be the most effective, lasting treatment for ADHD. (shrink)

This event-related potential (ERP) study examined the impact of phonological variation resulting from a vowel merger on phoneme perception. The perception of the /e/–/ε/ contrast which does not exist in Southern French-speaking regions, and which is in the process of merging in Northern French-speaking regions, was compared to the /ø/–/y/ contrast, which is stable in all French-speaking regions. French-speaking participants from Switzerland for whom the /e/–/ε/ contrast is preserved, but who are exposed to different regional variants, had to perform a (...) same-different task. They first heard four phonemically identical but acoustically different syllables (e.g., /be/–/be/–/be/–/be/), and then heard the test syllable which was either phonemically identical to (/be/) or phonemically different from (/bε/) the preceding context stimuli. The results showed that the unstable /e/–/ε/ contrast only induced a mismatch negativity (MMN), whereas the /ø/–/y/ contrast elicited both a MMN and electrophysiological differences on the P200. These findings were in line with the behavioral results in which responses were slower and more error-prone in the /e/–/ε/ deviant condition than in the /ø/–/y/ deviant condition. Together these findings suggest that the regional variability in the speech input to which listeners are exposed affects the perception of speech sounds in their own accent. (shrink)

Le regain d'interet pour la philosophie kantienne est ne en Allemagne vers 1860 et provient essentiellement d'un declin de l'idealisme hegelien, d'une reaction au materialisme, et d'un climat politique qui favorise un abandon des questions morales et politiques pour retourner a des problemes theoriques. De sorte que ce qui caracterise tous les neokantiens est leur volonte de redonner a la philosophie son statut scientifique au titre de theorie de la connaissance. Mais comment construire cette theorie de la connaissance est une (...) question qui donne lieu a des oppositions entre des auteurs qui se reclament pourtant tous de Kant. Or c'est precisement la subtilite des differences entre les ecoles de Heidelberg, de Marbourg, ou encore entre les pensees de Cohen, de Natorp, de Lask ou de Rickert, que nous permet de saisir cet ouvrage en nous offrant un eclairage essentiel.

The second volume in an unprecedented publishing event: the complete College de France lectures of one of the most influential thinkers of the last century Michel Foucault remains among the towering intellectual figures of postmodern philosophy. His works on sexuality, madness, the prison, and medicine are classics his example continues to challenge and inspire. From 1971 until his death in 1984, Foucault gave public lectures at the world-famous College de France. These lectures were seminal events. Attended by thousands, they (...) created benchmarks for contemporary critical inquiry. The lectures comprising Abnormal begin by examining the role of psychiatry in modern criminal justice, and its method of categorizing individuals who "resemble their crime before they commit it." Building on the themes of societal self-defense in the first volume of this series, Foucault shows how and why defining "abnormality" and "normality" were prerogatives of power in the nineteenth century, shaping the institutions--from the prison system to the family--meant to deal in particular with “monstrosity,” whether sexual, phsyical, or spiritual. The College de France lectures add immeasurably to our appreciation of Foucault's thought, and offer a unique window on his singular worldview. (shrink)

This conceptual paper draws on cognitive theory and attribution theory to develop a process model of managerial dissonance and responsibility attribution after harm-doing. Although extant harm-doing literature assumes managerial backing for such decisions, this study suggests that there will, at times, be acts of organizationally mandated harm-doing that managers believe are unnecessary. In these cases, it is proposed that managers will experience dissonance from enacting the harm-doing event, resulting in the externalization of responsibility to either the organization or the harm-doing (...) target. This paper examines the challenges faced by the manager through each phase of the dissonance resolution process and possible outcomes of the process. This study concludes with the model’s implications for moral theorizing. (shrink)

Dying serves so often within the narratives of Western popular culture, as an exercise in self-improvement both to the individual dying and to those looking on. It enlightens, ennobles and renders exceptional all those affected by it. Though mainstream cinema's “grammar of dying” is mired in similar myths, film has the potential to do dying differently: it can, instead, connect us, ethically, to the vulnerability of others. The aim of this article is to pursue this potential of film. Using the (...) mainstream grammar of dying as a starting point, I will consider how the moving image, and this ethical potential, is harnessed within two hybrid-media pieces about a loved-one's decline and death: George Saxon's art installation, “A Record of Undying” (2014) and photographer Briony Campbell's short film The Dad Project (2009). While these works will be located within the traditions and transformations of moving image practice, the primary concern here is with how such emotionally resonant pieces navigate our relation to, and responsibility for, our own and others' harsh realities. In this way, the question of ethics is grounded not in the solipsistic circuits of affective modes – whether as the catharsis or betterment of mainstream myths, or what Jane Stadler privileges as the ethical effects of empathy – but in something more inherently, more inevitably, political.

Within the Neoplatonic tradition, the absolute transcendence of the First Principle—the One-Good, from which the whole reality in its various articulations derives—plays a crucial role. This philosophical perspective implies, particularly in Plotinus and Proclus, some fundamental philosophical consequences, above all the transcendence of the Principle with respect to being and thought as well. This necessarily implies that the One-Good must be conceived of as beyond the intelligible Beauty itself. In this paper I aim to examine the theoretical implications and consequences (...) of this perspective with specific reference to the conception of God’s absolute transcendence outlined within two texts of the Corpus Areopagiticum, overall characterized by the reworking of some fundamental Neoplatonic concepts in the context of Christian theology: the De divinis nominibus and the De mystica theologia. Indeed, in the De divinis nominibus it is shown that the names/predicates attributed to God in the Sacred Scriptures must be understood only in an allegorical-symbolic meaning, because God is above any possible definition. Not even the character of Beauty can be attributed to him, since he radically transcends it: in fact, God constitutes the absolute foundation and the very first source of Beauty itself. Therefore, God must be understood as ἀκαλλής, that is, “devoid of the connotation of Beauty”, precisely because he completely transcends it. In line with this theological and theoretical perspective, in the De mystica theologia a form of radical and absolute apophatism is developed, which in turn must ultimately lead to its own overcoming for the sake of the henosis, the mystical union with God.
