Buy now to get the key takeaways from C. S. Lewis's Mere Christianity.

Sample Key Takeaways:

1) People quarrel over many things, but quarrels always involve one party trying to prove the other wrong. They almost always appeal to a set of inherent rules that everyone implicitly knows about human behavior. These rules make up the Law of Human Nature.

2) Similar to the law of gravity, the Law of Human Nature sets a precedent for how all humans should act and behave with others. However, unlike gravity, humans do not need to obey this law. While they know the law's inherent principles, they can choose to ignore them.
