At a time when misinformation, post-truths and conspiracies are undermining confidence in science, UNamur welcomes SPiN (Science & Philosophy in Namur), a new interdisciplinary research center that questions the place of science in society. Founded last September by Olivier Sartenaer, Professor of Philosophy of Science at UNamur, SPiN brings together philosophers and scientists around a common vision: to develop a critical and accessible reflection on science in all its diversity..

As part of its seminar, Centre Arcadie will be pleased to welcome Igor Krtolica for a session devoted to his book Romain Gary. De l'humanisme à l'écologie, Gallimard, 2025.Maître de conférences en philosophie à l'Université de Picardie Jules-Verne, junior member of the Institut universitaire de France, Igor Krtolica is the author (in addition to the work to be discussed) of Gilles Deleuze (PUF, coll. "Que sais-je? ", 2015), of Gilles Deleuze et Félix Guattari : Une philosophie des devenirs-révolutionnaires(Éditions Amsterdam, 2024) and of a commentary on an extract from Romain Gary's Les Racines du ciel entitled Antifascism, humanism and ecology (PUF, coll. "Classiques de l'écologie", 2025).After a presentation of the work, Igor Krtolica will be interviewed by Jean-Baptiste Vuillerod and Thibault De Meyer.Free admission. All welcome.Book presentation 1956: the Prix Goncourt is awarded to Racines du ciel, a novel whose hero, Morel, fights against the extermination of elephants in an Africa struggling for independence. Romain Gary described it as the first ecological novel. Ecology enabled him to resolve the unbearable political contradiction in which the post-war West finds itself: the impossibility of believing in man, the impossibility of giving up believing in man. How can we continue to give meaning to the idea of civilization? If we are to maintain the humanist ideal, we need to wage a battle in which man is no longer at the center. Such is the paradox explored here. This literary and philosophical essay reveals the complexity of Romain Gary's thought, his constant irony and humor, his contradictions, his rejection of dogmatism. And its modernity: ahead of his time, the novelist anticipated the controversies driving contemporary ecological thinking, where the human being is only a part of nature, but where nature itself becomes inseparable from history, society and politics. This previously unpublished synthesis of Romain Gary's work is an original analysis of the tension between humanist commitment and ecological cause.. Toutes les activités du Centre Arcadie

As part of its seminar, Centre Arcadie will be pleased to welcome Jeanne Etelain for a session devoted to her book Zones. Terre, sexes et science-fiction, Flammarion, 2025.Jeanne Etelain, PhD from New York University and Université Paris-Nanterre, teaches philosophy and contemporary theory at the École supérieure des Beaux-Arts de Montpellier.After a presentation of the book, Igor Krtolica will be interviewed by Jean-Baptiste Vuillerod and Thibault De Meyer.After a presentation of the book, Jeanne Etelain will be interviewed by Ludovic Dubois, Nathalie Grandjean and Sébastien Laoureux.Free admission. Welcome to all.Book presentation Zone: this ubiquitous term nevertheless remains elusive. In a stunning conceptual investigation at the crossroads of geography, psychoanalysis and science fiction, Jeanne Etelain explores how "zone" has become central to understanding space, in the contemporary context of a crisis in the planet's conditions of habitability. The zone thus emerges as a spatial modality that defies habitual categories, confronting us with space's power to act, whether it's nature, the Earth or the body. All Centre Arcadie activities

Conference organized by Centre Arcadie and the Department of Philosophy as part of the "Philosophie du cinéma" course and the "Cultures et pensées cinématographiques" Specialization Master's degree.Dork Zabunyan is Professor of Film Studies at Université Paris 8 Vincennes-Saint-Denis. His publications include Les Cinémas de Gilles Deleuze (Bayard, 2011), L'Insistance des luttes - Images, soulèvements, contre-révolutions (De l'incidence éditeur, 2016), Foucault va au cinéma (Bayard, 2011) with Patrice Maniglier, Jacques Rancière et le monde des images(Mimesis, 2023).In 2020 he published Fictions of Trump. Puissances des images et exercices du pouvoir(Le point du jour). In this conference, the aim will be to take up this work in the context of Trump's second term.Presentation of the workDonald Trump's body is almost everywhere, outside us, on our screens, caught up in information channels that disseminate still and moving images of him. He is also present within us, more or less floating, in the minds of his detractors and supporters alike. The 45th President of the United States of America is not, however, the book's only subject. Based on his countless audiovisual representations, both before and after his election, the aim here is to explore the function of images in the exercise of power today, the stories they tell and the discourses they condition. Two questions run through this essay: what is this strange love of power, conveyed by images of an authoritarian leader, to which individuals who have no interest in voting for him adhere? What filmic counter-fires, real or imagined, are likely to mobilize the powers of images to evade this power, or even to thwart it? All Centre Arcadie activities

It's official: the University of Namur joins the Réseau d'Échanges et de Liaisons entre Institutions d'Enseignement Supérieur Francophones (RELIEF). It thus becomes the fourth partner in this network, alongside the Université du Québec à Trois-Rivières (UQTR), the Université Savoie Mont Blanc and the Haute École Spécialisée de Suisse Occidentale (HES-SO).

Conceptual field theory and didactic situation theory Two complementary theories for thinking about and organizing mathematical learningIn the first part of this talk, I'll propose an introductory situation in literal arithmetic (Barallobres & Giroux, 2008) that will enable me to introduce and illustrate the main concepts and methodological tools of the theory of didactic situations developed by Guy Brousseau (Brousseau, 1997; Bessot, 2024). In the second part, I will give a brief presentation of Gérard Vergnaud's theory of conceptual fields (Vergnaud, 1990; Durand-Guerrier and Saby, 2023), then show how this theory helps to shed further light on the introductory situation.The contributions of the anthropological theory of didactics The Anthropological Theory of Didactics (TAD, Chevallard, 2001) aims to explain why and how a given knowledge lives in a certain institution, and/or is transformed as it passes from one institution to another. This perspective and some of its evolutions will be presented and illustrated in this talk.Students' activities and teachers' practices in the mathematics classroom: analysis methodology with Activity TheoryIn this talk, we will present the founding assumptions of the Activity Theory framework adapted to the Didactics of Mathematics (TADM, Vandebrouck, 2008), showing how this theory gives importance to fine-grained analyses of mathematical knowledge to appreciate classroom developments. We will then exemplify some of these aspects on the teaching of limits at university (Bridoux and Grenier-Boley, 2024).BibliographyBarallobres, G., & Giroux, J. (2008).

For its inaugural conference, the SPiN (Science & Philosophy in Namur) center will be joined by Claire Rommelaere, a lawyer and researcher at the Center for Bioethics at the University of Namur, and Aude Bandini, a philosopher of science at the University of Montreal, to take a critical look at the theme of "distrust of science." The urgency of addressing this issue is clear in our era, where, despite an overall stable level of trust in science, the parameters of public debate are frequently blurred by misinformation.Having had the opportunity to observe philosophers of science in their natural habitat for nearly fifteen years, Claire Rommelaere will share her thoughts on whether or not we should trust those who think about science.For her part, Aude Bandini will address a major problem that we all face at a time when the mass of available knowledge is such that it is impossible to acquire it on our own. Indeed, the socially distributed nature of knowledge generally leaves us no choice but to rely on the authority of experts, even on very important issues (such as health). However, when we rely on others in this way and follow recommendations that, due to our ignorance, we have no means of evaluating, we place ourselves in a relationship of "epistemic dependence" that conflicts with our aspirations for intellectual autonomy and forces us to ask ourselves a question whose answer may prove unbearable: is intellectual autonomy nothing more than a myth?Conference hosted by journalist Maïté Warland.Program:5:30-6:30 p.m. | Drinks at Quai 22 (Rue du Séminaire 22, 5000 Namur)6:30 p.m. | Claire RommelaereDistrust of philosophers of science7:00 p.m. | Aude Bandini Intellectualautonomy in the face of scientific authority: a headache for social epistemologyRegistration deadline: April 16.Free of charge.

Born on the internet, memes are an integral part of digital culture. These images, often humorous, combine text and visuals to convey a message. At UNamur, Lieven Vandelanotte, professor of English language and linguistics and general linguistics at the Faculty of Philosophy and Letters, has taken an interest in them from a linguistic point of view. In his new book, co-written with Barbara Dancygier of the University of British Columbia, he deciphers how these creations play with words, images, and grammar. 

The success of female Cistercian monasticism in the Southern Netherlands in the 13th century - over forty houses in the dioceses of Liège and Cambrai - is a powerful indicator of the aspirations of a society in transformation, enthusiastic about new forms of spirituality and religious life. For all that, the phenomenon remains surprisingly little studied, despite the wealth of archaeological and historical sources.
