Les biologistes décrivent actuellement une multitude de disruptions ayant lieu à tous les niveaux d’organisation du vivant, humains et non-humains. Ces disruptions proviennent principalement des technologies, qu’il s’agisse de la machine thermique issue de la première révolution industrielle, et du changement climatique subséquent, de la chimie avec notamment les perturbateurs endocriniens qui en sont issus, ou du numérique avec l’immixtion des écrans dans la relation parents-jeunes enfants (dans le cas des humains). Les infidélités du milieu ne sont pas étrangères au vivant comme le soulignait Canguilhem, mais la spécificité de ces disruption est leur rythme qui excède les capacité normative du vivant, humain et non-humain, conduisant à une contrepartie biologique de ce que Stiegler appelait la disruption comme régime actuel des sociétés humaines. Nous insisterons sur les conséquences de ces disruptions concernant le développement humain, biologique et psychique, et nous indiquerons des réponses possibles face à ces disruptions.

Physics has several concepts of randomness that build on the idea that the possibilities are pre-given. By contrast, an increasing number of theoretical biologists attempt to introduce new possibilities, that is to say, changes of possibility space – an idea already discussed by Bergson and that was not genuinely pursued scientifically until recently (except, in a sense, in systematics, i.e, the method to classify living beings). <br> Then, randomness operates at the level of possibilities themselves and is the basis of the historicity of biological objects. We emphasize that this concept of randomness is not only relevant when aiming to predict the future. Instead, it shapes biological organizations and ecosystems. As an illustration, we argue that a critical issue of the Anthropocene is the disruption of the biological organizations that natural history has shaped, leading to a collapse of biological possibilities.

Quatre-vingts ans après, Le Normal et le Pathologique est une référence majeure en philosophie mais qu’en est-il en biologie et en médecine ? Plus précisément, quelle est aujourd’hui la pertinence des concepts de Canguilhem dans la compréhension du vivant et de l’action concernant le vivant ?

"What I love, and those whom I love, you, that is to say us in so far as we are capable of forming a we, all this I love, and I love them, and I love you infinitely" (Bernard Steigler April 1952- August 2020). <br> When Bernard Stiegler writes "I love you" in the quote above, he openly provokes us to question or experience the meaning or contact of these words. He also invites us to question the relationship between a thinker’s life and their thought. For Stiegler, they were inextricable. His life was one that focused on friendship but not friendships at a purely social level but ones that produced philosophy, politics, and existential truths. <br> Bringing together scholars who knew Stiegler, including Shaj Mohan, Achille Mbembe, Divya Dwivedi, Peter Szendy, and Emily Apter, this volume provides an original - and personal - insight into his life and philosophy. Each piece gives a sense of the wide range of Stiegler’s work and how it affected the praxis of the philosopher in different parts of the world.

Mathematical modeling is a very powerful tool to understand natural phenomena. Such a tool carries its own assumptions and should always be used critically. In this chapter we highlight the key ingredients and steps of modeling and focus on their biological interpretation. In particular, we discuss the role of theoretical principles in writing models. We also highlight the meaning and interpretation of equations. The main aim of this chapter is to facilitate the interaction between biologists and mathematical modelers. We focus on the case of cell proliferation and motility in the context of multicellular organisms.

The program Plaine Commune, contributive learning territory, started in late 2016. It emerged from the theoretical work of Bernard Stiegler and the Ars Industrialis group. The contributive economy is a strategy to disrupt technological disruption by developing knowledge in all its forms. This program has led to several concrete working groups in Plaine Commune, while others are still developing. Mainly, work is taking place on the economy, digital urbanism, and young children’s development in the context of the overuse of digital media. Here, we focus on the group on digital media and young children’s development and how academics and inhabitant works integrate.
