Four phenomenal books

There are four books that I have read which I have found to be phenomenal. Until recently I have not been able to put my finger on why I found them so phenomenal. Now I know why: they start with simple concepts and gradually build on top of them. Each step adds a tiny bit of knowledge on top of the preceding steps. Each step logically follows from the preceding steps. Here are the four books:

1. An Introduction to Mathematics by Alfred North Whitehead.
2. Economics by Boyes/Melvin.
3. Wealth of Nations by Adam Smith.
4. Elements by Euclid.

Do you know of other books which follow this approach of starting with basic concepts and gradually, incrementally building up a vast body of knowledge?
