Neuroscience appears an unlikely place to search out basic truths that might apply to every thing within the universe. Brains are particular objects that do issues that few, if any, different objects within the universe appear able to. They understand. They act. They learn journal articles. They’re often the exception, not the rule.
That’s maybe why the free-energy precept (FEP) has garnered a lot consideration. What started within the early 2000s as a software to clarify cognitive processes like notion and motion started to be introduced as a “unified brain theory”. Then the FEP outgrew the mind, being put ahead as a definition of life and, inevitably, as the idea for a brand new form of synthetic intelligence that may purpose. At the moment, some proponents argue that the FEP even encapsulates what it means for one thing within the universe to exist in any respect. “You can read the free-energy principle as a physics of self-organisation,” says its originator, Karl Friston at College Faculty London. “It is a description of things that persist.”
But some researchers are sceptical that the FEP can stay as much as lots of its loftiest guarantees, having grown pissed off with its shifting scope. “It has been a moving target,” says Matteo Colombo, thinker and cognitive scientist at Tilburg College, the Netherlands.
All of which has made the FEP a supply of each fascination and frustration. Its dizzying breadth is vital to its enduring enchantment, even whereas it stays famously troublesome to get your head round. So, given the claims that it may be used to clarify…
