Summary

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.

I'm your host Sean Carroll.

And in the course of doing many podcasts, interesting phenomena arise when I look at

what the comments are and from various sources, whether it's email or Twitter or comments

0:14.8

on the web page or on YouTube or Reddit, different podcast episodes have different spirits in

0:20.9

some sense.

0:21.9

Sometimes we're big picture, right?

0:24.9

We're sort of talking about various ideas from a very high level view and it's more inspirational

0:32.9

than challenging, right?

0:34.2

It's like thinking about things rather than getting a lecture in them.

0:37.8

Other times we get a little deeper.

0:39.6

We kind of get our hands dirty.

0:41.0

We get into the weeds.

0:42.0

We try to dig into some specific example of something.

0:45.2

Either way, I will get complaints that I know.

0:48.5

And you know what?

0:49.5

I love and cherish the complaints because I want constructive feedback.

0:53.0

I want to hear what people have to say, but honestly going forward realistically, it's

0:58.5

going to be a mix of both kinds.

1:00.8

So today we're getting our hands dirty.
