Karl Friston
Neuroscientist. Creator of the Free Energy Principle and active inference framework. Formalizes the mathematical backbone for ⟨V, G⟩.
Key Contributions
- Free Energy Principle: All adaptive systems minimize surprise (free energy) to maintain their existence
- Active inference: Behavior as organisms rolling toward free energy minima on a landscape
- Markov blankets: Self-assembling boundaries at every scale that define inside/outside
- Generative models: Agents carry models of their environment and act to confirm predictions
Role in the Mesocosm
Friston provides the mathematical formalization for exterior-intelligence. His framework describes agents navigating landscapes to maintain coherence — exactly the ⟨V, G⟩ architecture. Markov blankets self-assemble at every scale, from cells to organisms to societies.
Connection to Other Traditions
Friston's work converges with Waddington's epigenetic landscape (1957), Levin's bioelectric fields, Gibson's affordances, Ratliff's geometric fabrics, Pāṇini's kāraka system, and the Vedantic model of consciousness descending through levels. This convergence from eleven independent directions is strong evidence for the exterior model.
The Free Energy Principle also connects to consciousness-first frameworks through its path integral formulations. Fields, Friston, Glazebrook, and Levin (2022) reformulated the FEP in scale-free quantum information theory, and Friston's 2019 monograph derives the Schrodinger equation as a special case of the FEP for "small things" -- bridging active inference and quantum mechanics.
