Spyridon wants to "understand." Spyridon is looking for answers to the questions we have all asked at some time or other: Who created the world? Where do we come from? Are we alone in the universe? Is there another reality behind this one?... This is the story of his adventures: his encounters with famous men and the incredible plan he will build to obtain some answers. "Spyridon's Quest" is like a children's tale for adults. During his journey, Spyridon learns, doubts, thinks and makes notes in his little yellow notepad. He discovers surprising and incredible things, true things. Spyridon does not accept ready-made answers or simplified solutions. He is critical towards man's ego and sceptical of any solution that would give a special place to humanity in the universe. He is, without knowing it, a defender of "Ockham's razor," the principle of parsimony: do not make any hypothesis that you do not need. He fears unconscious premises that guide us without our knowing it. Spyridon believes his adventure has a meaning. He will discover one that he could never have imagined.
