This book addresses its subjects to four categories of readers:
a - The Intellectuals and Researchers:those are the dynamic true participants and beneficiaries of these researches, they can take it from here and go further and deeper in the subjects discussed or spinned-off to other fields.

They can help pave the way for the individual in our societies to reach a logical and rational thinking from which he was denied and kept in the dark for a long time.

For them, I made it very easy since I have provided all references by volumes and page numbers.

b - The Average Reader: who does not read a lot, and is occupied constantly in his daily life. Generally, he has no deep awareness of our history and culture.

This person can benefit from this book, because of its simple, straightforward and easy to understand language, after he sees before his own eyes the truth and the facts that should be understood logically and intelligently. He does not need more details to reach a good perception with his correct state of mind.

c - The Ulamaa' (scholars): who are knowledgeable of the issues discussed, they are invited here to examine and rethink with a new vision to bring about the inevitable changes which must occur to enlighten our people.

d - The Waez (the knowledge pretender) who looks at issues with one eye - half closed - but considers himself the Guru of knowledge who has the authority and the will to cause much more damage than he can comprehend, I hope to succeed to bring back to common sense some of those as well.

Briefly, I can say that this book can best be described as "a mirror" that every reader in those 4 categories can see himself in , and then he or she decides how useful they can be for themselves in particular and for humanity in general.
