CHAPTER

The Free Energy Principle

The idea behind the free energy principle is let's get the rest of physics working in the background. So you get your classical statistical and quantum mechanics working with all of those. And then you ask a simple question, what could it possibly mean to re identify some state as the system is being the same state over time? And so, yeah, unpacking that question leads to a Bayesian mechanics. This is also what makes it unique among other candidates in the cognitive sciences and the biosciences. It’s connecting the thermodynamic entropy of the states the system is made of to the beliefs, the probabilistic beliefs that those states encode. The equations of motion that you write down
