The text examines the problematic nature of defining the concept of the subject and its associated ontological frameworks. The author argues that before attempting a definition, it is necessary to clarify fundamental conceptual models such as event-based processes, internal and external aspects, action, reaction, and memory. The subject is not viewed as a simple primary entity, an object, or an unchanging substance, but rather as a complex, non-objective reality. The analysis distances itself from traditional Aristotelian categories and transcendentals, characterizing the subject as an active organization of relations that constitutes and transforms itself through its own activities. A major methodological obstacle in grasping the subject is the prevailing tendency of human thought toward objectification, which is fundamentally unsuited for understanding the non-objective nature of subjectivity. Consequently, the author suggests that an adequate conceptualization of the subject requires the development of a new type of non-objectifying thought. This approach would transcend the classical categories of Aristotle or Kant, allowing the subject to be understood as a dynamic, irreducible whole within its ongoing activity.
