This is a book with a hard background work of mediation and writing, including topical culture issues. It is not only an invitation to the understanding and growing of the Christian thought and philosophy, but an example of how to make Christian philosophy, with an understanding purified by faith and guided by the polar star – stella rectrix – of the Christian revelation. What is trendy in culture may not be the only topical issue, but also what is missing, what we can not find. Today’s culture has an excess of what is ephemeral, of lots of fireworks and lots of emptiness. There is hunger and thirst of principles, foundations, desire of truth, unity and beauty.
