#67 Prof. KARL FRISTON 2.0

Mar 2, 2022

In this enlightening discussion, Karl Friston, a leading British neuroscientist from University College London, delves into the intriguing free energy principle and its impact on cognition and consciousness. They explore the challenges of simplifying complex scientific concepts and the balance of order and chaos in existence. Friston also interrogates the essence of consciousness, questioning if it can be recreated in silico, while tackling the complexities of free will in a deterministic universe. A thought-provoking conversation that intertwines science, philosophy, and self-discovery!

We engage in a bit of epistemic foraging with Prof. Karl Friston! In this show; we discuss the free energy principle in detail, also emergence, cognition, consciousness and Karl's burden of knowledge!
