From State to Mode: Criticality and Non-Factorizability as Constitutive Properties of Living Systems
Zenodo (CERN European Organization for Nuclear Research) June 26, 2026 Wolfgang Stegemann
Criticality in autopoietic (living) systems is not merely a state the system can be in, as in non-living dissipative systems, but a mode of operation that defines the system as living. This mode, present from the earliest autopoietic systems, develops qualitatively new forms as the nervous system scales. In the nervous system, this mode realizes non-factorizability as a stable operating condition. This reframing clarifies that epilepsy and coma are not opposite ends of an activation spectrum but structurally distinct failures of this critical mode in opposite directions.
