Karl Friston, a leading neuroscientist and pioneer of the free energy principle, dives deep into the intersection of biology and physics. He explores the concept of Markov blankets, discussing how they define boundaries within living organisms. The conversation also touches on active states and their influence on behavior, alongside the fascinating link between Bayesian dynamics and Darwinian mechanics. Friston further examines the implications of the free energy principle and how it can shape our understanding of self-organization in complex systems.

Episode notes
Markov Blankets
- A Markov blanket is a statistical boundary separating a system's internal states from external states.
- It's crucial for individuating some'thing' from everything else.
Markov Blanket Bipartition
- Markov blankets partition states into internal, external, sensory, and active states.
- Active states influence the external world, while sensory states are influenced by it.
Pullback Attractors
- Systems revisit similar states over time, shown by pullback attractors.
- Random fluctuations prevent exact repetition, like snowflakes or heartbeats.
