Kathryn Nave, "A Drive to Survive: The Free Energy Principle and the Meaning of Life" (MIT Press, 2025)

The cybernetic tradition in cognitive science analyzes the purposive behavior of many complex systems – from sensory-guided missiles to sensory-guided animals -- in terms of feedback control that maintains stability in the face of external perturbation. A more recent extension and elaboration of this framework brings in predictive processing and the minimization of free energy – essentially, minimizing getting inputs that conflict with what the system expects. In A Drive to Survive: the Free Energy Principle and the Meaning of Life (MIT Press, 2025), Kathryn Nave argues that this framework is inadequate for explaining living organisms, which are not merely complex but inherently unstable and continually producing themselves through metabolism. Nave, who is a Leverhulme Trust Early Career Research Fellow at the University of Edinburgh, defends a bioenactivist view of living organisms in which the chemical and energetic constraints involved in having a metabolism are essential for understanding their actions, in contrast to the “sensor-guided movementism” of the FEP framework.
