This text examines the ontological relationship between the subject and the event, defining the subject essentially as a non-object. The process by which an event establishes its subject leads to their mutual identification and subsequent transformation. A purely non-objective subject becomes a concrete reality only through the process of concrescence—the fusion of its non-objective and objective aspects. This transformation allows an originally virtual event to become an intra-worldly reality that is available to its surroundings. The author further analyzes the interaction between events-subjects, which is conditioned by their specific level of reactibility. Most events respond to their environment as an indefinite sum of external influences rather than to individual events, as the internal subjective side of every true event remains fundamentally inaccessible to external observation and influence. The abstract thus elucidates the dynamics of how real actuality emerges from a non-objective foundation and explores the limits of mutual interaction between individual entities within a processual understanding of the world.
