L’article décrit trois statuts que l’on peut envisager en philosophie pour l’objet mathématique : le statut de point d’appui pour un discours que l’on tient par avance pour vrai (_l’objet_ _enfant de la vérité_), le statut d’objet qui se présente et que l’on connaît en tant qu’il se présente (_l’objet_ _se présentant_), et finalement le statut métaphysique d’objet se répétant, donnant lieu à de la différence sans concept (_l’objet idéal, faisant défaut à son identité_). Les trois (...) statuts sont pris au sérieux et considérés comme correspondant à des intérêts légitimes. Dans le cours de la discussion, on croise le dilemme de Benacerraf, le débat Brouwer-Hilbert et diverses conceptions kantiennes ou husserliennes. (shrink)

La theorie physique? Ce titre, qui fut au debut de notre siecle celui d'un ouvrage controverse, suggere bien une question, celle de savoir si en matiere de science la theorie doit se qualifier en fonction d'un domaine plus particulier d'application. L'auteur, Pierre Duhem, n'aurait pas hesite, semble-t-il, a repondre par l'affirmative en ce qui concerne le vaste champ de la recherche que l'on peut signifier sous le nom de physique. Son ouvrage est en fait construit comme une preparation rigoureuse a (...) une telle reponse et bien que les annees aient modifie considerablement le contexte du champ sus-dit, les analyses proposees ont ete jugees suggestives par de nombreux epistemologues d'aujourd'hui.

This article makes the case for a symmetry between the form and content of Lacan's 1964 seminars on vision in The Four Fundamental Concepts of Psychoanalysis. As well as theorizing anamorphosis, or visual resistance, as a model of the dialectic between the eye and the gaze, the seminars function to lure and frustrate their auditor-readers. This reading, supported by Lacan's references to his own discourse as a labyrinth and network of threads, shows how a policy of syntactic ambiguity and apparent (...) contradiction seems to inform the logic of the seminars on vision, such that the gaze defies understanding as surely as it resists the eye. The article proposes that this structure of mise-en-abyme, discussed as hypnotic even within the discourse on the gaze, is designed to captivate auditor-readers. Elements within the seminars, as well as Lacan's ‘post-face’ to the published edition, suggest that the discourse is addressed to our unconscious. (shrink)

The purpose of this paper is to report on the creation and the transmission of mathematical knowledge linked to combinations thanks to a specific material object namely diagonally-divided paving stones which are squares diagonally divided into two different colours. The diagonally-divided paving stone is alternately considered as an ornamental piece, a subject for study from the 18th century in Mémoire sur les combinaisons by Father Sébastien Truchet from the French Royal Academy, an educational tool in Édouard Lucas’ Récréations mathématiques in (...) the 19th century or a play object. This all constitutes an original form of patrimonialization of mathematical knowledge based on an object often considered as a simple toy. (shrink)

Comment comprendre la publicité, sa communication, son rôle dans la société ? En répondant à cette question, cet article aura pour but de montrer que la publicité, au-delà de sa dimension fonctionnelle, offre des prothèses identitaires dans un monde social où les repères sont de plus en plus flous et évanescents.How can one understand advertising, its communication, its role in society ? By answering this question, this article will aim to show that advertising, beyond its functional dimension, offers identity prostheses (...) in a social world where bearings are increasingly vague and elusive.

Locke distingue : la connaissance intuitive, la connaissance rationnelle et la connaissance sensitive. C'est par celle-ci que nous accédons à la connaissance des « autres choses ». Or on peut se demander comment le sens peut être à la fois juge et témoin. En fait, pour Locke, notre connaissance des choses hors de nous a une « fiabilité effective », mais ce n'en est pas une connaissance parfaite, laquelle nous est inaccessible. Locke distinguishes : intuitive knowledge, rational knowledge, and sensitive (...) knowledge. It is through the latter that we reach the knowledge of « other things ». Now, one may wonder how can sense be both at the same time judge and witness. In fact, according to Locke, our knowledge of things outside ourselves bears some « effective reliability » but it is not necessarily a true knowledge, which is indeed unattainable. (shrink)

Based on the presentation of a research framework (the shared work of teachers), this text uses an empirical approach to examine the hypothesis of a co-elaboration of the professional situation. To do so, the empirical investigation, based on the Goffman framework, analyzes the process of reconstructing a teaching session (reference situation) over the course of a pedagogical counselling session (support situation) characterized by interaction between a beginning teacher and a trainer. The invalidation of the hypothesis leads to a suggested conceptualization (...) of the professional situation combining definitional approaches (emphasizing the duality between its singularity and its genericity) and methodological approaches.

Gadgets : the Religion of Objects in a Comprehensively Administered Society The fall-out from commodity violence is evident in the current status of gadgets, here considered as an ideal-type. The article therefore puts forward an analysis of four instances of gadgetised subjectivity, whose interpenetrations can be located in the categorical architecture of the « new » and the « post ». The task of a psychodynamics of gadgets would therefore involve an unravelling of the links between dead objects and subjectivities (...) converted into a mystico-positivist substance. (shrink)
