The text presents a philosophical analysis of the concept of action within the context of event-based occurrence and the constitution of the subject. It distinguishes between mere activity and true subjective action, which requires the subject to emerge from the totality of the event. The primary form is defined as random action, through which the subject gathers information from its environment. This experience is stored in a subjectal sphere, acting as a reservoir of pseudo-objectivity that enables future targeted actions. The author emphasizes that the progression of an event is not strictly determined by external causal laws but involves moments of uncertainty. These moments allow the subject to be sensitive to non-objective appeals and challenges. Thus, action is not a simple causal reaction to a stimulus but an active performance based on internal planning and accumulated experience. This approach challenges traditional causal interpretations and views subjectivity as an essential agent in the unfolding of events.
