This text explores the ontological concept of event-driven occurrence, viewing the event as a subject capable of performing its own being. A central theme is the process of self-constitution, where the flow of occurrence precedes the formal establishment of the subject. For an event to maintain its actual existence—conceived here as life in a broad sense—it must continuously re-establish itself and build upon its previous states. This process requires the event to constitute itself as a subject endowed with the power to preserve its integrity and prevent fragmentation. Without this internal subjective structure, an event could not return to itself during its course or integrate elements from its spatial and temporal environment. The author emphasizes that incorporating past actions and external influences is crucial for an event to sustain its identity and evolve toward higher levels of complexity. Ultimately, the document reflects on the temporality and dynamic nature of being within the framework of event-based ontology.
