The text examines the function of the subject as the founder and guarantor of the internal integrity of a 'true being.' The author highlights the dialectical relationship between a being and its subject: while the being depends on the subject, it must also establish and maintain it. This apparent contradiction is resolved through the concept of 'pure non-objectivity,' which provides a founding act that the subject cannot initially perform on its own. This necessary act is attributed to the subject as an act of faith, thereby taking on the character of a gift. The work demonstrates that the subject's activity is inherently rooted in the future, which is the source of all newness. Subjectivity is understood not as a static datum but as a dynamic performance conditioned by external transcendence and openness to the future. This approach bridges ontological reflections with a philosophical analysis of faith and the nature of time.
