The book is an exception in contemporary philosophical literature because it presents a comprehensive, synthetic vision of reality. It is written in the current of Aristotle-Tomistic philosophy, but it also uses many insights of thinkers from other directions. It combines into one whole claims from the main branches of philosophy: theory of knowledge, metaphysics, philosophical anthropology, social philosophy, philosophy of nature, and philosophy of God. On this basis, it proposes a project of scientific psychology, empirically verifiable but also open to a supernatural reality. One can find here proposals for answers to the most important philosophical questions, especially existential ones. It clearly separates what is commonly accepted in science or philosophy from what is authorial and thus controversial, and therefore provides good material for discussion.

This volume is for everyone who wants to understand reality and find their place in it. Its sequel will be a book: “Principles of spiritual development. How to become God, that is oneself?”
