Relating Interface Theory and Active Inference

In this landmark Mind-Body Solution Colloquia, cognitive scientist Donald Hoffman and neuroscientist Karl Friston engage in a deep, rigorous dialogue on the foundations of reality, perception, and consciousness.Hoffman argues that spacetime and physical objects are not fundamental, but evolved interfaces shaped by fitness rather than truth. Friston presents the Free Energy Principle and Active Inference as a unifying framework for life, mind, and meaning — raising the question of whether inference itself can ground reality.Together, they explore:- Why spacetime may be derived, not fundamental- Whether consciousness must come before physics- Markov blankets, trace logic, and system boundaries- Probability, inference, and non-equilibrium dynamics- The limits of scientific explanation- Implications for AI, evolution, and ontologyThis is not a debate — it is a serious attempt to understand reality at its deepest level.TIMESTAMPS:(00:00) - What is Ultimately Real?
