It seems to me that the free-energy principle (FEP) is little more than a restatement of the principle put forth by chemist Henry Louis Le Chatelier: “If a system is subjected to stress, the system will respond in a manner that tends to mitigate the effect of the stress.” I can’t see that the fuzzy notions of the FEP offer anything beyond this (19 October, p 32).
