Books outlining the natural law


I’ve been wondering on the exact contents of the natural law. What is wrong and why? Can anyone direct me to some books or articles outlining the exact contents of the natural law? Thanks.


John Finnis is a good Catholic source on that topic. I have his book “Moral Absolutes”, but he also has a book “Natural Law and Natural Rights”, which I have not read.

According to Catholic teaching, the entire moral law is found in natural law. See the CCC, n. 1954 and following.

Pope Saint John Paul II talks about natural law in his encyclical:
Veritatis Splendor
