Free energy helps us understand how we behave. In fact, so let me sort of repeat the thing that I read. And then, again, you'll fix it. One way of thinking about what happens when I move my hand is that there seems to be a mismatch between where my hand actually is and where my brain thinks it is. But rather than fix my brain, I move myhand to bring it to where it is. Is that? That's beautiful. I don't need to fix anything there. We should celebrate that because what you've just described is a modern day recount of idea motor theory which was prevalent in the 19th century - Helmholtz. Yes. Well,

If you tell me that one of the world’s leading neuroscientists has developed a theory of how the brain works that also has implications for the origin and nature of life more broadly, and uses concepts of entropy and information in a central way — well, you know I’m going to be all over that. So it’s my great pleasure to present this conversation with Karl Friston, who has done exactly that. One of the most highly-cited neuroscientists now living, Friston has proposed that we understand the brain in terms of a free energy principle, according to which our brains are attempting to model the world in such a way as to minimize the amount of surprise we experience. It’s a bit more complicate than that, but I think we made great headway in explicating some very profound ideas in a way that should be generally understandable.
