The text examines the ontological nature of the subject through the concept of the "event-being." The author argues that for subjectivity to be established, an event must be capable of relating to itself as a whole, which constitutes the primary form of reflection or the "turn back" toward oneself. However, a "first-order" event cannot achieve this self-relation in isolation; it requires the assistance of other events. This primal reflection is not merely a matter of memory or the reconstruction of past occurrences. Instead, the unification of the "whole" must encompass not only what has already happened but, more importantly, what is yet to happen or what may potentially occur. Thus, subjectivity is presented as a dynamic process that transcends simple presence and integrates the past with the open horizon of the future. This perspective emphasizes the relational and temporal integrity of the subject within the framework of processual existence.
