This text explores the ontological distinction between existence, being, and mere occurrence. The author argues that existence should be attributed exclusively to true beings rather than mere aggregates or heaps. Every true being is understood as a genuine event whose being is temporally and spatially coextensive with its duration, yet it does not reside in any unchanging substance. A central theme is the conceptualization of being as an active performance. The text further distinguishes between the primordial performance of one's own being and actual action, which emancipates itself from this foundation to target external goals that are not originally part of the being. The capacity to perform one's own being, or rather the actual realization of this capacity, is specifically identified as existence. This perspective rejects traditional substance-based ontology in favor of a dynamic view of being as a processual unity that constantly constitutes itself through activity. Existence is thus viewed as an active self-transcendence and self-creation of the being within the flow of time.
