Concepts and principles for the new biology: Development, disruption and normalization

During the first 25 years of the 21st century, we witnessed a resurgence of Organicism. This process is characterized by the return of the organism as a central biological entity and the increasing investigation on purpose and normativity at this level.
Simultaneously, the issue of the vulnerabilities of living beings and their numerous disruptions is escalating in urgency. The need to comprehend these disruptions, and how living beings adapt to them, is pressing. Organicism, with its systemic approach to disruptions and its focus on organisms’ normativity, is the most suitable framework for this understanding.
In this session, we will:
1) explore the epistemological role played by the morphogenetic field concept in the studies on the etiology of tumors in the early 20th century and its resurgence in the organicist conception of cancer as development gone awry (presented by Claudia Gadaleta, Paris 1 Sorbonne Panthéon - IHPST, Paris, France),
2) argue that a properly fleshed-out concept of disruption describes the effects of a significant category of detrimental anthropogenic causes in organisms and ecosystems. Understanding disruptions requires articulating historical and relational reasoning, which is a hallmark of recent theoretical developments (presented by Maël Montévil, Centre Cavaillès, Ecole Normale Supérieure, Paris, France)
3) argue that disruption causes a loss of function. The organismal agency may overcome disruption by acquiring novel functions, a process we call normalization. We will discuss two examples: i) how young quadrupeds that lost the function of their forelimbs teach themselves to walk as bipeds, and ii) cancer, a disease usually perceived as irreversible but known to regress spontaneously by normalization (presented by Ana Soto, Tufts University, USA and Centre Cavaillès, Ecole Normale Supérieure, Paris, France).
