This text offers a philosophical analysis of the process of thematization, interpreted as a specific act performed by a subject. The author emphasizes that every instance of thematization involves not only the theme itself but also the means used and the agent performing the act. This performance, as an expression of subjectivity, is irreducible to the thematic content. A central aspect of the reflection is the critical reassessment of the traditional concept of the "object." The author suggests that "non-objects" can also be the focus of thematization, raising crucial questions about the consequences of treating non-objective realities as if they were objects. This methodological perspective allows for a deeper reflection on intentionality and the boundaries between what can be grasped as an object and realms that elude standard objectification. The work provides significant insights for phenomenological inquiry into the nature of thought and its directedness, while warning against the distortions that arise when ontological categories are conflated during the process of cognition.
