In the third part...

In the third part, we will study the principle and laws of causality that govern the world, as well as the comprehensive philosophical explanation of the world that causality offers us. We will also treat a number of philosophical doubts that have emerged in light of recent scientific developments. From there, we will move to the fourth part [concerning] matter and God[^4].

This discussion relates to one of the final stages of the conflict between materialism and theology, so that we can form our theological notion of the world in light of the philosophical laws and the various natural and human sciences. In the final part, we will study one of the most significant philosophical problems namely, that of knowledge - which constitutes an important area of conflict between materialism and metaphysics.

The discussion is treated on philosophical grounds and in light of the various sciences that are related to the subject, be they natural, physiological or psychological. This is a general, comprehensive outline of the book. It is now in your hands as a result of ten months of successful efforts that led to its production in the present form. I greatly hope that it will carry out faithfully and sincerely something of the holy message. (p. 9).

I ask the dear reader to study the investigations of this work in an objective fashion, with complete concentration and reflection, judging, in conformity, or against it, on the precise philosophical and scientific criteria available to him, and not emotionally. Further, I do not wish to have him read the book as he would read a play or a kind of intellectual or literary luxury. The book is not a play, a literary piece, or an intellectual luxury.

Rather, at heart, it is concerned about the problems of reflective human beings. My success is only from God on Whom I have relied and to Whom I resort.

Is there such a thing as false knowledge, for example? [^2]: Georg Wilhelm Friedrich Hegel, German philosopher (1770-1831).

He taught that the rational is the real, and the real is the rational. Opposites are essential elements of change, as Heraclitus had believed. The pattern of change takes the form of triads: thesis, antithesis and synthesis.
