The Free Energy Principle, Consciousness & Psychedelics with Dr. Adam Safron

This episode is a bit of a wild one. It's a three hour discussion bringing together a unifying principle for life, the free energy principle (a topic I explored in greater detail in my conversation with Maxwell Ramstead), with several pernicious problems that have plagued us for years, like consciousness, free will, intelligence, and what the hell is going on when we take psychdelic substances.

The Constructal Law with Prof. Adrian Bejan

The constructal law is a law of physics that predicts natural design and its evolution in biology, geophysics, climate change, technology, social organization, evolutionary design and development, wealth and sustainability. The law states that for a finite-size flow system to persist in time (to live) it must evolve such that it provides greater and greater access to the currents that flow through it. If the second law of thermodynamics is seen as the irreversibility of energy flow, the...

The Free Energy Principle with Dr. Maxwell Ramstead

The Free Energy Principle is a formal description of how life resist entropy across scales by minimising surprise. Surprise here being an information-theoretic view of how unlikely a particular sensory state of an organism is, not the psychological phenomenon of surprise — though they are definitely linked. The free energy principle describes how organisms attempt to reduce the difference between their model of the world and their perception of it. Joining me to shed light on this topic is...
