    Bernard Stiegler: Friendship and Fellowship

    On Bernard Stiegler - Philosopher of Friendship


    When I first met Bernard Stiegler, he was starting his program in Plaine Commune, a suburb of Paris that mixes misery of all kinds with young and creative vitality.

    Abstract

    "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).
    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.
    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.

  2. Mathematical modeling in the study of organisms and their parts

    Mathematical modeling in the study of organisms and their parts

    Systems Biology 2nd edition


    How do mathematical models convey meaning? What is required to build a model? An introduction for biologists and philosophers.

    Abstract

    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.

    Plaine Commune, contributive learning territory

    Memories for the Future: Thinking with Bernard Stiegler


    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.

    Abstract

    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.

  4. Modeling organogenesis from biological first principles

    Modeling organogenesis from biological first principles

    Organization in Biology: Foundational Enquiries into a Scientific Blindspot


    Here we discuss the application and articulation of biological principles for mathematical modeling of morphogenesis in the case of mammary ductal morphogenesis, with an emphasis on the default state.

    Abstract

    Unlike inert objects, organisms and their cells have the ability to initiate activity by themselves, and thus change their properties or states even in the absence of an external cause. This crucial difference led us to search for principles suitable for the study organisms. We propose that cells follow the default state of proliferation with variation and motility, a principle of biological inertia. This means that in the presence of sufficient nutrients, cells will express their default state. We also propose a principle of variation that addresses two central features of organisms, variation and historicity. To address interdependence between parts, we use a third principle, the principle of organization: more specifically, the notion of the closure of constraints. Within this theoretical framework, constraints are specific theoretical entities defined by their relative stability with respect to the processes they constrain. Constraints are mutually dependent in an organized system and act on the default state.
    Here we discuss the application and articulation of these principles for mathematical modeling of morphogenesis in a specific case, that of mammary ductal morphogenesis, with an emphasis on the default state. Our model has both a biological component, the cells, and a physical component, the matrix that contains collagen fibers. Cells are agents that move and proliferate unless constrained; they exert mechanical forces that i) act on collagen fibers and ii) on other cells. As fibers are organized, they constrain the cells’ ability to move and to proliferate. This model exhibits a circularity that can be interpreted in terms of the closure of constraints. Implementing our mathematical model shows that constraints to the default state are sufficient to explain the formation of mammary epithelial structures. Finally, the success of this modeling effort suggests a step-wise approach whereby additional constraints imposed by the tissue and the organism can be examined in silico and rigorously tested by in vitro and in vivo experiments, in accordance with the organicist perspective we embrace.

  6. Comment le hasard façonne le vivant ?

    Comment le hasard façonne le vivant ?

    Figurer le hasard : questions de théorie


    En biologie, le hasard est une notion essentielle pour comprendre les variations ; cependant, cette notion n'est généralement pas conceptualisée avec précision. Nous apportons ici quelques éléments allant dans ce sens.

    Abstract

    La physique possède plusieurs concepts de hasard qui reposent néanmoins tous sur l’idée que les possibilités sont données d’avance. En revanche, un nombre croissant de biologistes théoriciens cherchent à introduire la notion de nouvelles possibilités, c’est-à-dire des modifications de l’espace des possibles - une idée déjà discutée par Bergson et qui n’a pas été véritablement poursuivie scientifiquement jusqu’à récemment (sauf, en un sens, dans la systématique, c’est-à-dire la méthode de classification des êtres vivants).
    Alors, le hasard opère au niveau des possibilités elles-mêmes et est à la base de l’historicité des objets biologiques. Nous soulignons que ce concept de hasard n’est pas seulement pertinent lorsqu’on cherche à prédire l’avenir. Au contraire, il façonne les organisations biologiques et les écosystèmes. À titre d’illustration, nous soutenons qu’une question cruciale de l’Anthropocène est la disruption des organisations biologiques que l’histoire naturelle a structurées, conduisant à un effondrement des possibilités biologiques.

  8. How does randomness shape the living?

    How does randomness shape the living?

    Figuring Chance: Questions of Theory


    In biology, randomness is a critical notion to understand variations; however this notion is typically not conceptualized precisely. Here we provide some elements in that direction.

    Abstract

    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).
    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.

  9. Conceptual and Theoretical Specifications for Accuracy in Medicine

    Conceptual and Theoretical Specifications for Accuracy in Medicine

    Personalized Medicine in the Making: Philosophical Perspectives from Biology to Healthcare


    We question some aspects of medicine from the perspective of theoretical biology, on the one hand, and the technological and social dimension of health and disease on the other hand.

    Abstract

    Technological developments in genomics and other -omics originated the idea that precise measurements would lead to better therapeutic strategies. However, precision does not entail accuracy. Scientific accuracy requires a theoretical framework to understand the meaning of measurements, the nature of causal relationships, and potential intrinsic limitations of knowledge. For example, a precise measurement of initial positions in classical mechanics is useless without initial velocities; it is not an accurate measurement of the initial condition. Conceptual and theoretical accuracy is required for precision to lead to the progress of knowledge and rationality in action. In the search for accuracy in medicine, we first outline our results on a theory of organisms. Biology is distinct from physics and requires a specific epistemology. In particular, we develop the meaning of biological measurements and emphasize that variability and historicity are fundamental notions. However, medicine is not just biology; we articulate the historicity of biological norms that stems from evolution and the idea that patients and groups of patients generate new norms to overcome pathological situations. Patients then play an active role, in line with the philosophy of Georges Canguilhem. We argue that taking this dimension of medicine into account is critical for theoretical accuracy.

    Abstract

    Pour progresser sur la question du rapport entre l’informatique et le calculable, je propose de réinterpréter l’objet de l’informatique théorique puis de faire un détour par la biologie théorique où la question d’un symbole qui empêche de calculer se pose. Enfin, je reviens vers l’informatique en transférant de manière critique certains concepts issus de mes travaux en biologie théorique.
