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 lines 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. Surprise conversation starters in this episode: Philosopher Alva Noe on the puzzle of perception Learn more about your ad choices.
