This text critically examines Jan Patočka's 1969 formulation regarding the "creation of being" and "ontogenetic function," arguing that being is not created but rather performed. The author challenges the notion that a subject—whether a human being or Hegel's Absolute Spirit—can create its own being from nothing. Although the Spirit realizes and performs its being through activity and praxis in nature and history, it cannot be regarded as its own creator in an absolute ontological sense. This principle is applied to the human phenomenon: an individual must already "be" in order to begin performing their being and subsequently transforming themselves. The analysis emphasizes the fundamental distinction between performance (praxis) and original creation, thereby questioning certain modern interpretations of ontology and subjectivity. The study concludes that while a subject becomes itself through the performance of being, this process is always conditioned by a prior existence, rejecting the idea of absolute self-creation and highlighting the necessary ontological preconditions for any subjective activity.
