The philosophical concern is inextricably linked to the deeper quests of humanity throughout the ages. We are confident that the issues addressed in the following pages are not only problems that occupy all those who participated in the extensive discussions of the Philosophical Café.

They embrace the deeper reflections of all consciousnesses and thus offer themselves as a familiar dialogue rather than merely personal interpretations. We therefore attempt a depth reflection with infinite respect for tradition, the wisdom of cultures, and human inquiries. This endeavor, long-term and persistent, has in its portfolio dozens of books, lectures, studies, and so on.

For this reason, in the following pages, citations of sources, historical retrospectives, and positions that have been developed are avoided. This does not mean, of course, that the reader must necessarily refer to our earlier texts. Simply put, topics that have been studied and are revisited are considered developed in other texts.
