This text explores the ontological relationship between an event and its subject. The author argues that the subject cannot be derived from any pre-existing entity; instead, it is the event itself that constitutes, creates, and transforms its subject. Consequently, the event precedes the subject in both a logical and ontological sense. This concept raises a critical question regarding the nature of an event before it has established its subject. The author characterizes such an event as "virtual"—lacking relationships with its environment and the capacity for self-relation. The transition from a virtual event to a real one depends on establishing interactions with its surroundings. Every action or reaction by the event toward its environment is not merely an external intervention but a process through which the subject itself is formed and refined. The reflection concludes by addressing the problem of how a virtual event transforms into a real one and the limitations of an external description of the interactions that lead to the establishment of subjectivity.
