Huh, have you ever wondered what a sandwich sounds like?

Not much to it, is there?

Unless, of course, it's a Walker's sandwich.

Mmm, that is good.

Now that's what Asani should sound like.

Go all crisp in with walkers.

Delicious.

Hi there, I'm Jason Gottz, and you're listening to Think Again, a Big Think podcast.

You're a body in the world.

From the moment you're born, from that very first gasp of air, you're taking in sensations,

trying to get a handle on things

and the relationships between them. There's a lot of things to get a handle on. Too many. So your

brain needs to simplify. It makes boxes for objects, maps them onto grids to track their motion. Through

this process, the physical world enters your mind. It makes your mind. And that's where things

start to get really interesting. My guest today is cognitive psychologist Barbara

Tversky. Her new book, Mind in Motion, How Action Shapes Thought, Upends Everything Most of

Us Think We Know About Thinking. Tversky's first law of cognition is that there are no

benefits without costs.

We simplify the physical world, reduce it to wines and boxes.

We build abstract thought, everything from Shakespeare to string theory to how to design a pair of sneakers on top of that same flawed foundation.

And that explains all of our superpowers and all of our blind spots.

Welcome to think again, Barbara.
