Way of God: Derech Hashem by Moshe Chaim Luzzatto.

It is very logical and is set out in parts that are divided into a few chapters. The parts are:
1. Fundamentals, covering The Creator, Man, Human Responsibility.
2. How Providence Works.
3. The Soul, Inspiration and Prophecy,.
4. Serving God, Love and Fear of God, Prayer.
