This section is a complement to the overall, comprehensive proof of Islam in the form of a discrete technical summarization of concepts already discussed. Proof is attained with individual understanding and acceptance of the Quran and Islam alongside Pure Reason. However, with this section, one who is willing to find the truth and do what it takes to accept it should have the tools necessary to begin navigating their understanding, ultimately next to the Quran and acceptance of proof and Islam. The Proof of Islam is in Part 3, and one can skip to read that, but it might benefit to understand more about metaphysics and reason as an introduction to the Proof in the first two sections.
As an addendum, the philosophical branch of study this entire document highlights is metaphysics. Metaphysics is the source of philosophy itself: what is reality, what is our consciousness, what is the relationship between our consciousness and reality, what makes something Be the way it is. It is concerned with the ultimate nature of reality, and it inherently entails questions of Belief and Disbelief.
