This text explores the ontological relationship between an event and its subject. The author posits that an event does not unfold in discrete phases but rather as a unified whole. In the case of complex super-events that encompass numerous sub-events, there is a necessity for a unifying principle that allows the entire scope of the process to be actualized at any given moment. This principle is identified as the subject of the event. The subject is not an external entity but a constitutive element that must remain present throughout the event's duration to bridge its individual moments. The text emphasizes that an event continuously constitutes and restores its subject, thereby ensuring its own actual existence. Rather than viewing the subject as a static foundation, the author presents it as a dynamic outcome of the eventual process, essential for the integrity and continuity of complex occurrences. This perspective shifts the traditional understanding of subjectivity toward a process-oriented ontology where the subject is defined by its functional role within the event.
