This text explores the origin and maintenance of the integrity of a subject, conceptualized as an event. The author argues that integrity cannot be imposed from the outside, nor can it be entirely inherent from the start, as the subject initially emerges through a transition from potentiality into actual reality and subsequent past-ness. The central philosophical problem lies in the moment of inception: how something that is not yet a subject establishes itself as one, and whether every emergence is inherently the birth of a subject. The author suggests that integration into larger, more complex entities depends on the activity and performance of the subjects themselves, guided by specific know-how which, in the organic world, is transmitted genetically. The document concludes that investigating these ontological foundations will require a long-term effort and a willingness to reformulate the fundamental questions if current approaches prove inadequate for understanding the genesis of subjectivity.
