• category_theory being used to map the “morphisms of interaction” across physics, computer science, biology, cognitive science, etc.
• Approaches

   2. compositionality
   3. behaviors = parts + rules (morphism)
4. The Free Energy Principle (Karl Friston)
   1. the_free_energy_principle
   2. Not strictly category theory but it still a mapping of interactions between underlying_principles
