This text examines the ontological definition of an event as a dynamic process characterized by its internal unification within time. The author emphasizes the critical necessity of developing an adequate conceptual framework and specific terminology to reflect the unique nature of events, avoiding the limitations of traditional linguistic structures. Drawing inspiration from Alfred North Whitehead’s innovative approach—which employs psychological terms within physical contexts—the author interprets the event as an entity that actively "performs its being." Consequently, an event is conceptualized as an active subject rather than a passive recipient of change, possessing its own agency and capacity for performance. The central philosophical inquiry focuses on the internal norms and rules that govern the event-subject in its activities. By redefining the event as a self-governing subject, the text explores the internal logic and ontological autonomy of processual phenomena. It underscores the vital relationship between language, thought, and reality, suggesting that new terminology is essential for a deeper understanding of how events are structured and sustained.
