One of the most important books that explain and analyze existential philosophy, which has been of interest to a group of intellectuals in the world and certainly in Egypt. It is presented in an enjoyable and smooth manner by an experienced writer in philosophy and life, the creative writer Anis Mansour, who says about the book: "Existentialism does not comfort the reader, nor does it comfort those who understand it." Nor does he live it... because it awakens every sense in him and hangs lights and bells on all his functions, qualities, faults, hopes and fears. It does not comfort, but rather frightens... it frightens you, because it places a great responsibility on your shoulders. It makes you a legislator for yourself and for all people... isn't that? Scary? That is why the easiest way in philosophy is to read about the philosophical doctrine... or about the philosopher, any philosopher, and after that comes approaching the philosopher himself... As for going to the philosopher directly, it is difficult and it is better to go to his acquaintances, friends, or neighbors."
