A plant does not seem to have much in common with animals. Yet naturalists of the eighteenth and nineteenth centuries attempted to study plants as if they were animals: they set out, for example, to find an equivalent to the circulatory or respiratory systems. Why did they feel the need to resort to analogical reasoning? What results did they obtain? And more generally, what is the value of this type of reasoning?On the agendaTuesday, May 5, 202612:15 PM – Welcome and light lunch1:30 PM – Introductory remarksThibault De Meyer (University of Namur): Why Analogy?2:15 PM – Session 1: Theory and Practice - Cristiana Oghina-Pavie (University of Angers): The analogy of pragmatic knowledge: actions and transactions in 19th-century horticulture and Quentin Hiernaux (FNRS / Free University of Brussels): The plant-animal analogy employed by A.-P. de Candolle’s physiology in addressing the issue of the sensitivity of living beings3:45 PM – Coffee break4:15 PM – Plenary Session 1 - Thierry Hoquet (University of Paris Nanterre): Is the plant/animal analogy valid?5:45 PM – End of the first day7:00 PM – Conference dinnerWednesday, May 6, 20269:00 AM – Welcome9:15 AM – Session 2: Relationships and Boundaries of the Living - Dario Galvão (University of Namur): Analogy and the Faculties of the Living: Animal Reason and Plant Sensibility in the Enlightenment and Ugo Batini (University of Poitiers): Understanding Humanity Through Plants: Analogy and the Metaphysics of the Living in Schopenhauer10:45 AM – Coffee break11:15 AM – Plenary Lecture 2 – Pascal Duris (University of Bordeaux): Plants as Humans.

In 2025, two iconic Walloon products—Walloon honey and Liège white blood sausage—were awarded the prestigious European PGI designation. Behind this success lies the AgriLabel project, to which UNamur has been contributing for over a decade. Working alongside producers, specialists, and public institutions, our Department of History played a decisive role: demonstrating, through historical sources and scientific analysis, the close connection between these products and their local terroir. A project at the heart of economic, identity-related, cultural, and scientific issues.

Constitutionalism, understood as a means of establishing a political autonomous from society, is seen as having constructed the opposition between the State and society. At the same time, the concept of constitutionalism is increasingly being used to describe other forms of social power and normativity – such as the economy, finance, digital, technologies, media, environment – even though the concrete and theoretical implications of these shifts have not always been fully clarified. More recent trends have emerged within the framework of socio-constitutionalism or societal constitutionalism to challenge the reduction of constitutional issues to state-individual relations, acknowledging the complexity of power. Despite their heterogeneity in assumptions, as well as in their descriptive, normative, and theoretical dimensions, these approaches have contributed to renewing the inquiry into the relationship between constitution and society. The purpose of the conference is to assess the current boundaries of constitutionalism and to explore theoretical proposals seeking to overcome them. These approaches raise several fundamental questions: What role should be granted to social actors and sectors within constitutionalism? How can their normative autonomy be acknowledged while also regulating their private power and expansionist tendencies? To what extent do these transformations challenge traditional forms of politics? At what cost might the relationship between constitution and society be reconsidered today?  Program January 299:00 a.m. Welcome9:30-10:00 Introduction: Manon Altwegg-Boussac (Paris-Est Creteil University/IUF) and Sabina Tortorella (MSCA/University of Namur)From State to Society: New Challenges for ConstitutionalismChair: Isabelle Aubert (Paris Panthéon-Sorbonne University)10:00-10:30 Thomas Boccon-Gibod (Grenoble Alpes University): Relationships between Constitution and Society10:30-11:00 Simone Mao Zhenting (Harvard University): Constitutionalizing Society in an Age of Fragmented Authority: From State-Centrism to Social Constitutional Norms11:00-11:30 Discussion11:30-12:00 Coffee Break12:00-12:30 Angelo Jr Golia (Luiss Guido Carli): Societal Constitutionalism and General Theory of Law (beyond the State): Norm, Order, Interpretation12:30-12:45 Discussion12:45-14:30 LunchMoving Beyond the Nation-State: Theoretical PerspectivesChair: Eleonora Bottini (Sciences Po)2:30-3:00 p.m. Jean-François Kervégan (Paris Panthéon-Sorbonne University): Politics below and beyond the State: Schmitt and Kojève in Comparative Perspective3:00-3:30 p.m. Paul Linden-Retek (University at Buffalo School of Law): Postnational Society and its Law3:30-4:00 Discussion4:00-4:30 p.m. Coffee BreakNew Conceptual Tools: Alterity and DerogationChair: Eleonora Bottini (Sciences Po)4:30-5:00 p.m. Horatia Muir Watt (Sciences Po): On the Borderline (and beyond the State): Ontologizing Alterity on the Terms of the Law5:00-5:30 p.m. Raffaele Bifulco (Luiss Guido Carli): Derogation as Legal Response to Social Differentiation5:30-6:00 p.m. Discussion6:00 p.m. DinnerJanuary 309:00 a.m. WelcomeMapping Sectoral Constitutions: Case StudiesChair: Sabina Tortorella (MSCA/University of Namur)9:30-10:00 Francesco Martucci (Panthéon-Assas University): Trust and Distrust.

After a presentation of the book, Déborah V. Brosteaux will be interviewed by Thibault De Meyer and Vivien Giet.Free admission. Everyone is welcome.Book presentationFaced with the wars in which European countries are involved, we constantly oscillate between numbness and frenzy. Some war situations give rise to emotional heatedness, a "renewed" psychic and social energy, while others are barely mentioned, relegated to the background. This philosophical investigation delves into the ambivalence of our relationship to war, which is at the heart of the sensitive history of modernity.Inspired by the writings of Walter Benjamin, W. G. Sebald, and Klaus Theweleit, the book explores these warlike emotions throughout the 20th century and questions their legacy: the coldness of distancing, the denial of the ruins after 1945, the desire to intensify the experience of self, which mobilized the imagination in 1914-1918 and was swallowed up in the trenches... even mutating into fascist passions that actively fed on the devastation.Déborah V. Brosteaux takes these desires seriously, including their appeal. And she asks: what emotional transformations can be activated to resist the mobilization of war?  More information about the ARCADIE Center

Well hidden from passersby, caves nevertheless conceal particularly aesthetic secrets. For the past four years, Martin Vlieghe has been pursuing a PhD in geology at UNamur.  He is exploring the origin of the surprisingly varied colours of certain concretions nestled in the heart of Belgian and French caves. Together with Prof. Johan Yans and Gaëtan Rochez, he samples, observes, and analyses these magnificent objects with the aim of uncovering the mysteries they conceal.

In the coming months, the University of Namur will participate in an exceptional space mission aboard the International Space Station (ISS), alongside Belgian astronaut Raphaël Liégeois. The BeBlob project, led by researchers Boris Hespeels (ILEE Institute) and Anne-Catherine Heuskin (NARILIS Institute), aims to study the DNA repair capabilities of a fascinating organism: the blob (Physarum polycephalum).

Are we prisoners of our genetic heritage? Can filiation be reduced to genes alone? Can we escape our destiny? Existential questions we all ask ourselves, and to which Gaëlle Pontarotti, lecturer and researcher in the Department of Sciences, Philosophies and Societies at UNamur, sheds new light in her book Par-delà les gènes. Une autre histoire de l'hérédité, published last October by Gallimard.

Today, our planet is undergoing major climatic changes. Particularly in the face of rising temperatures, it is not easy to predict how flora and fauna will react and adapt in disturbed ecosystems. International research, in which Professor Johan Yans' team (Department of Geology and ILEE Institute) is taking part, has found some answers in fossils, which have been the memory of Darwinian evolution for millions of years.

This doctoral study assesses pathways to enhance coastal sustainability in the Anthropocene, by promoting the sustainable use of mangroves and strengthening their social-ecological resilience through an interdisciplinary approach. The thesis is structured into four specific objectives: assessing the role of traditional beliefs and local deities in promoting the sustainable use of mangroves, analyzing the synergies between legal frameworks and traditional beliefs in enhancing the social-ecological resilience of mangroves, developing a novel interdisciplinary framework to evaluate the social-ecological resilience of mangroves, and operationalizing the proposed framework in Benin's mangroves, West Africa.  We collected field data using ethnobiological surveys, drone image analysis and document review, in-depth interviews, focus group discussions, plant and fish inventories across three coastal communities in Benin. The study draws insights from the seven principles of resilience to analyze mangrove sustainability. The interdisciplinary methodology of this study links plant biology, fisheries sciences, and human geography to analyze mangroves as complex social-ecological systems. Findings of the thesis show that traditional beliefs and local deities play a significant role in regulating the use of mangrove resources, while the overlapping of formal and informal institutions offer opportunities to enhance their social-ecological resilience. The novel proposed framework called Mangrove Social Ecological Resilience Appraisal (MaSERA) outlines variables and indicators tailored to mangroves to assess their social-ecological resilience. Its application in Benin highlights its potential in identifying factors that enable or erode mangrove resilience, for informed decision making. The study argues that promoting the sustainable use of mangroves and enhancing their social-ecological resilience represent dual imperatives for achieving coastal sustainability in the Anthropocene. It contributes to the growing body of knowledge on mangrove conservation and provides actionable insights for integrated coastal zone management.

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.

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..
