About This Book
What if learning wasn’t just about facts but about figuring out what’s really true and necessary in your mind? Imagine your brain as a builder, constantly using what it already knows to create better ideas. But what happens when those ideas don’t quite fit together? The challenge is to fix the mistakes before you can understand the world better.
