This text examines the relationship between interiority, non-objectivity, and subjectivity within the conceptual model of the subject. While a subject's interiority correlates closely with its non-objective side, subjectivity is a distinct phenomenon that cannot be reduced to simple interiority. Subjectivity is characterized by a dual nature, encompassing both objective and non-objective dimensions, and functions as a sphere of "pseudo-events" occurring within consciousness. The author argues that the integrity of subjectivity is not inherent or biologically determined; rather, it must be actively and strenuously maintained by the subject itself. There is a fundamental gap between organic integrity and the integrity of thought or consciousness. Maintaining this mental cohesion requires continuous effort, and any weakening of the subject leads to the fragmentation of subjectivity. The text thus highlights the active role of the subject in constituting its own sphere of consciousness.
