The purpose of this article is to propose a synthesis of Jacques Poulain's philosophical reflection on language and its importance for human being and for the society. To do this, we begin with presenting what Poulain has constantly established in the light of anthropobiological knowledge in his various works by showing that the child does not directly enter the world through senses or action, but through language and that it cannot enter the world and become a subject able to think (...) and act in isolation, but necessarily through the intermediary of a Third of speech. The same goes for the author at the institutional level, since man, as a being of language, has only been able to transform himself indirectly, through the intermediary of this Third of speech, which first took the form of the gods, then by making the detour of the judgment. Today, as Poulain argues in polemic with Jürgen Habermas, there can be no other basis for global communication than transcultural linguistic understanding, ie. language constitutes the space where man can be recognized, exercise judgment and strive for harmony with others.

Die vorliegende Sammlung von Aufsätzen einiger der weltbesten Spezialisten der antiken griechischen Philosophie konzentriert sich auf die philosophischen Texte, die während der hellenistischen und kaiserlichen Zeit Pythagoras und den Pythagoreern zugeschrieben wurden. Ihre unbekannten Verfasser behaupten, die Positionen der ursprünglichen pythagoreischen Schule zur Metaphysik, Theologie, Zahlenphilosophie, Physik, Logik, politischen Philosophie, Ethik und zur richtigen Lebensweise zu vermitteln. Die kühnsten unter ihnen präsentieren sich als die Quellen, aus denen Platon und Aristoteles die Inspiration für den Timaios und die Kategorien geschöpft haben. (...) Da sie von den meisten antiken Denkern als maßgebend angesehen wurden, führte dies zu einer Renaissance der platonischen und pythagoreischen Tradition. (shrink)

In Being and Time, Heidegger affirms that being-with or Mitsein is an essential constitution of Dasein but he does not submit this existential to the same rigorous analyses as other existentials. In this essay, Jean-Luc Nancy points to the different places where Heidegger erased the possibility of thinking an essential with that he himself opened. This erasure is due, according to Nancy, to the subordination of Mitsein to a thinking of the proper and the improper. The polarization of Being-with between (...) an improper face, the Anyone, and a proper one, the people, which is also, as Nancy shows, a polarization between everydayness and historicity, between a being-together in exteriority (indifference and anonymity) and a being-together in interiority (union through destiny), between a solitary dying and the sacrificial death in combat, leaves the essential with unthought. This essay shows not only the tensions that arise out of Heidegger’s own analyses of Mitsein and affect the whole of Being and Time but also underlines in the end a “shortfall in thinking” inherent not only to Heidegger’s work but, as Nancy claims, to our Western tradition, a shortfall which Nancy has attempted to remedy in his Being Singular Plural.

Contemporary research on racial categorization is mostly encompassed by two research traditions—social constructionism and the cognitive-cum-evolutionary approach. Although both literatures have some plausible empirical evidence and some theoretical insights to contribute to a full understanding of racial categorization, there has been little contact between their proponents. In order to foster such contacts, we critically review both traditions, focusing particularly on the recent evolutionary/cognitive explanations of racial categorization. On the basis of this critical survey, we put forward a list of eleven (...) requirements that a satisfactory theory of racial categorization should satisfy. We conclude that despite some decisive progress, we are still far from having a complete theory of why humans classify people on the basis of skin color, body appearance or hair style. (shrink)

In many real-life situations, we are interested in the value of a physical quantity y that is difficult or impossible to measure directly. To estimate y, we find some easier-to-measure quantities x1, … , xn which are related to y by a known relation y = f. Measurements are never 100% accurate; hence, the measured values equation image are different from xi, and the resulting estimate equation image is different from the desired value y = f. How different can it (...) be? Traditional engineering approach to error estimation in data processing assumes that we know the probabilities of different measurement errors equation image. In many practical situations, we only know the upper bound Δi for this error; hence, after the measurement, the only information that we have about xi is that it belongs to the interval equation image. In this case, it is important to find the range y of all possible values of y = f when xi ∈ xi. We start the paper with a brief overview of the computational complexity of the corresponding interval computation problems: Most of the related problems turn out to be, in general, at least NP-hard. In this paper, we show how the use of quantum computing can speed up some computations related to interval and probabilistic uncertainty. We end the paper with speculations on whether “hypothetic” physical devices can compute NP-hard problems faster than in exponential time. Most of the paper's results were first presented at NAFIPS'2003 [30]. (shrink)

L'extrême barbarie de la seconde guerre mondiale, et l'espoir d'une vie différente pour l'humanité, ont amené M. Merleau-Ponty à réfléchir sur le marxisme - théorique d'une part, stalinien d'autre part. Notre projet consiste à suivre son cheminement intellectuel à cet égard depuis ses premiers écrits politiques de '45 jusqu'en I960, quelques mois à peine avant sa mort subite survenue il y a exactement trente ans, en mai 1961. Mais en quoi est-il pertinent, à l'heure où un vent d'Histoire plane sur (...) l'Est, de revenir sur des textes dont certains atteindront bientôt le demi-siècle ? C'est que l'auteur a vu clair avant presque tout le monde, de telle sorte qu'il réussit à identifier, inscrite dès l'origine dans son propre système, l'asphyxie inévitable du régime soviétique. Aussi, lire le Merleau-Ponty de ces années pas si lointaines, c'est lire à notre avis l'URSS de Gorbatchev et voir également s'épanouir la nouvelle Europe depuis Prague jusqu'à Sofia. C'est comprendre du même souffle - ce que n'eût point désavoué Marx - qu'on ne saurait bâillonner indéfiniment, enracinée dans le tissu de l'homme, la Volonté-de-liberté des peuples et des nations.The extreme barbarity of the Second World War, and the hope for a different life for Humanity, lead Merleau-Ponty to reflect on marxism, theoretical as well as Stalinian. Our aim is to follow his intellectual progress on this subject since his first political writing, from 1945 until I960, that is, just a few months before his sudden death in may 1961. However, where is the relevance to come back to these fifty years old texts when History blows on eastern countries? Simply because Merleau-Ponty has foreseen the present situation almost before any other analyst, in such a way that he identified successfully the unavoidable asphyxia of the soviet regimen, as inscribed at the very outset of this political system. To read the Merleau-Ponty of these years, it is, do we think, to read the USSR of Gorbatchev, and to see also the new Euro pa to expand, from Prague to Sofia. It is also to understand, by the same occasion - and Marx would not have disavowed it -, that one cannot silence indefinitely the Will of liberty of people and nations which is routed in the nature of man.

La pregunta crucial en todas las culturas a lo largo de los siglos es la pregunta por el Fundamento de lo real. Pero es posible pensar el Fundamento -articularlo especulativamente- o nos tenemos que contentar con nombrarlo? O podemos narrarlo, contar su historia? Esa pregunta por el Fundamento esta presente tambien en la filosofia de Paul Ricoeur; recorriendo su obra, descubrimos diversas zonas de pensamiento en las que esa interrogacion surge y resurge, implicita o explicitamente, bajo la forma de una (...) flecha que trata de indicarnos por que camino podria encontrarse la respuestra; se diria que la ontologia es como un guia fiel que acompana la aventura de Ricoeur.

This paper is the text of a lecture given at Sofia University St. Kliment Ohridski on 2 November 2023 at the invitation of Professor Irena Kristeva. Its purpose is to retrace the path of my research, from the question of the Animal in the eighteenth century to the theme, at the same time, of the environment associated with the construction of the modern Ego and which gave rise to my latest book published in 2020: Figures of the Self and the (...) Natural Environment in the Eighteenth Century. Throughout, the common thread remains to understand the link between these two processes and the new Anthropology being established at the time, whether in terms of the new definition of Man in general in relation to the Animal, or of the Self in relation to the natural Environment. At the same time, this sensitivity to Nature paved the way for our contemporary ecology, both scientific and political. (shrink)

The aim of J.-L. Marion’s article is to revisit the important debate on the place of Augustine in the history of metaphysics. Often, quibbles arise upon considering the use of substance (substantia) by Augustine, not only as approximative of essentia and as synonymous with ousia, but in deciding whether in so doing Augustine effectuates a ‘metaphysical turn’. While he elsewhere argues that Augustine is a pre-metaphysical thinker, in this article Marion focuses on showing the diverse range of usages of the (...) term substance in the Augustinian corpus. Marion observes: first, whenever substance seems a fixed definition, the term allows for equivocity; second, God is substance in an indeterminate sense or by negation; third, human beings are substances fundamentally to capture the mutability of human existence. As such, Marion concludes, the Augustinian use of substance is insufficient to inelude Augustine in the history of metaphysics. (shrink)

This essay traces the phenomenon of revelation beginning with the humblest, to the most personal, to the most exalted. Through this analysis, we discover several qualities of revelation: it reveals itself from itself, reveals a new world to me, and reveals another me to myself and to others. Turning to divine Revelation, a further set of concepts is uncovered: the witness who encounters a Revelation without understanding it, a resistance to the testimony of the witness, and a paradox that provokes (...) this resistance by exceeding expectations. These qualities make Revelation both more intelligible and meaningful. For, while holding an exceptional privilege, divine Revelation nonetheless remains in continuity with phenomenality in general and, in arriving from elsewhere by its own initiative, it opens my eyes to the unfolding of its unseen reserves.

Is “philosophy after automation” a theme or a question? One might hesitate about this, because we may wonder whether or not it implies that philosophy could disappear after automation, or at least be subject to serious revision. Philosophy could be read as a historical movement towards self-determination [autodétermination] as well as the exposition of the limit of such a program of archi-autonomy. The Cartesian event is essentially ambivalent, and man alone in the world is undoubtedly also the one who can (...) but alter, in the long run, the sufficiency of the auto. This is what we can now begin to understand. (shrink)

The authors analyze Takhtajan's system of classification of the Angiosperms in relation to the principles of evolutionary and cladistic systematics. It is shown that Takhtajan belongs to the evolutionary school: he identifies the ancestors of some taxa, he accepts polytomous branching and he groups taxa on the basis of primitive as well as derived character states. Takhtajan's notion of weighted similarity does not appear to be based on objective criteria, when determining the weight and evolutionary status of characters.After a summary (...) of the modifications brought out by Takhtajan in his 1980 version, the weak and strong points of evolutionary systems as a whole are emphasized. In these, the delimitation of taxa and their filiation are difficult to refute since they do not rely on precise criteria, which would ensure continuity and uniformity within a given system. However, these systems have some flexibility, which allows them to incorporate readily new information, a feature unfortunately missing in cladistic classifications. In fact, while it does have weaknesses from a theoretical point of view, the system of Takhtajan gives us an idea of flowering plants phylogeny that appears to be one of the most complete at the present time from both analytical and synthetic standpoints.

Créativité et mathématiques ne font pas bon ménage dans l'inconscient collectif. Pourtant à l'heure d'Internet, il existe bien une manière de revisiter la géométrie, l'algèbre ou même la logique. Il suffit de prendre un peu de distance par rapport aux calculs, de se donner quelques libertés par rapport à l'histoire, de changer de point de vue... En vagabondant à travers l'histoire et l'application des mathématiques, les auteurs se livrent ici à un jeu de vulgarisation d'une saveur et d'une subtilité inédites. (...) [4e de couv.]. (shrink)

Some original forms of state emerge from the clan structures in central Africa in the 16th and 17th centuries, beyond the reach of any European influence. The oral epic traditions which echo these events draw from the founts of Bantu mythic thought. The Luba national epic recounts the dramatic origin of its sacred royalty and describes the passage from a primitive culture to a refined civilization, from an uneventful history to one full of movement; but above all it abandons itself (...) to a singular meditation on the ritual usage of fire, on family and death, on time and space, on the rainbow and lightning. If we take the fantastic seriously, symbolic patterns appear which filter the historical tradition and transform it into metaphysics. The reeling King Woot seems to play in reverse the Luba role, on the royal scene of Kuba mythology, where almost Biblical figures could be recognized: the tower of Babel throws its shadow on the adventures of an African Noah who first abandons himself to drunkenness, then to incest, delivering society to the diversity of languages and plunging the universe into primordial chaos. A transition between the myth and the tale, the founding epic of the Lunda state is bathed three times in blood: the blood of the warriors, of the women, and of the beasts who fall prey to a marvelously seductive hunter. Looking closely, we see that this Prince-stranger, initiator of a line of anointed royalty, carries on his shoulders, as does his Luba counterpart, a part of the universe. The cosmogony is veiled in the myth but transparent in the ritual, in the actions and mysterious words of the initiates into mungonge religious society: men with eyes of light are the counterpart of animals with eyes of darkness, as the star of day is opposed to the sinister hyena-moon. The founding epic of the Bemba state tells, like the Kuba myth, of the fascination of the principle of pleasure among a migrating aristocracy, somewhat decadent in comparison with the rude warrior or hunter heroes in the Luba and Lunda epics. But all these narratives, in the final analysis, form one sole myth, which develops its autonomous structures under the turbulence of an historical adventure each time different. More than unfolding the particular story of each kingdom, these legendary chronicles of Zaïre, Zambia and Angola reveal that the powerful political organisations set up by the Bantu to the south of the great forest are not isolated from eacb other: they administrate in common an intellectual patrimony which breaks loose from the ideological role that the kings, whether drunk on palm wine or on military ambition, try to make them play for their own glory: myths and rites obey their own codes, recognize no master but one, which they give themselves in their own kingdom: the Imaginary. The text which follows here is concerned in particular with the epic of the Bemba people, whose dominating aristocracy imposed an anointed royalty on some 100,000 people formerly grouped in matrilinear clans.

IntroductionAlthough the motor signs of Parkinson’s disease are well defined, nonmotor symptoms, including higher-level language deficits, have also been shown to be frequent in patients with PD. In the present study, we used a lexical decision task to find out whether access to the mental lexicon is impaired in patients with PD, and whether task performance is affected by bradykinesia.Materials and MethodsParticipants were 34 nondemented patients with PD, either without medication or under optimum medication. A total of 19 age-matched control (...) volunteers were also recruited. We recorded reaction times to the LDT and a simple RT task. In each task, stimuli were either visual or auditory. Statistical analyses consisted of repeated-measures analyses of variance and Tukey’s HSD post hoc tests.ResultsIn the LDT, participants with PD both off and on medication exhibited intact access to the mental lexicon in both modalities. In the visual modality, patients off medication were just as fast as controls when identifying real words, but slower when identifying pseudowords. In the visual modality of the control task, RTs for pseudowords were significantly longer for PD patients off medication than for controls, revealing an unexpected but significant lexicality effect in patients that was not observed in the auditory modality. Performances of patients on medication did not differ from those of age-matched controls.DiscussionMotor execution was not slowed in patients with PD either off or on medication, in comparison with controls. Regarding lexical access, patients off medication seemed to have difficulty inhibiting a cognitive-linguistic process when it was not required, and exhibit a specific pseudoword processing deficit in the LDT, which may have been related to impaired lateral word inhibition within the mental lexicon. These deficits seemed to be compensated by medication. (shrink)

Le passé de l’Occident reste marqué par une tache indélébile, celle de l’horreur de l’esclavage colonial. Il est certes aujourd’hui avéré que la traite atlantique ne fut que l’une des traites négrières, à côté de la traite arabe au travers du Sahara et le long des côtes de l’océan Indien, qui s’étale sur une plus longue durée, et des traites africaines internes au continent... Mais en elle s’exprime un scandale spécifique, celui de la contradiction entre une pratique et des idéaux (...) proclamés, qui furent d’abord ceux d’une religion à vocation universaliste prônant l’amour du prochain, puis ceux issus des Lumières, dont l’application fut loin d’être immédiate. En outre, concentrée sur une période de temps plus brève – en gros trois siècles et demi, du début du XVIe au milieu du XIXe siècle –, la traite atlantique a alimenté en force de travail servile non pas des sociétés à esclaves, comme le furent les sociétés arabo-musulmanes, mais des sociétés esclavagistes, dont le caractère totalitaire résultait d’un mode de production tout entier fondé sur l’utilisation d’une main-d’œuvre dégradable autant que l’exigeaient les contraintes des cultures de plantation, vouées à la satisfaction de marchés extérieurs , et donc sur une marchandisation et une réification de l’homme sans précédent. Ce qui en fait un phénomène éminemment moderne, en contrariété avec les usages antiques ou non occidentaux, caractérisé par une racialisation de l’oppression, avec la mise en place d’un préjugé de couleur qui servit de légitimation commode, sous le couvert de la nature, à une forme d’exploitation qui aurait pu paraître condamnable en fonction des valeurs religieuses et politiques officiellement affichées.
