This text examines a fundamental shift in the philosophical understanding of arché, or the origin of all things. The author contrasts the ancient Greek conception, which viewed arché as a governing principle and a fullness from which everything is derived, with the concept of nothingness. For Greek thinkers, the idea of emptiness as a beginning was entirely foreign, as they perceived the origin as a permanent and ruling foundation. The emphasis on nothingness emerged primarily in early Christianity through the doctrine of creatio ex nihilo (creation out of nothing). Although originally a theological defense against the Greek notion of God as a mere organizer of pre-existing chaos or matter, the philosophical implications of this idea were profound. Once the concept of nothingness was emancipated from its theological origins, it enabled a view of being as an event with a distinct beginning and end. This new understanding allows for the emergence of something truly new that did not exist before, transforming static ontology into a dynamic perception of the event-like nature of reality.
