Law**

This book is very interesting! It uses simple mathematical formulas to describe the deep logic of law and human moral intuition, allowing me to see the evolutionary history of law. I especially like the "law of return" mentioned in the book. It makes me understand that the source of the law is actually very simple. As the book says: "The oldest source of law should be the simplest algorithm." This sentence impressed me deeply. It is recommended that you also read it, you will gain something different!
