This text examines the concept of metaphysics as the study of being as being, starting from Aristotle’s definition in the Metaphysics and Heidegger’s interpretation in his introduction to What is Metaphysics. The author critically evaluates the formula "being as being" and proposes a reinterpretation through the temporal character of beings. If we understand a being as an event, it becomes clear that it cannot be present in its entirety at any single moment. The currently actual "beingness" represents only a small fraction of the whole, while its past and future phases are currently "non-being." The author argues that to fully comprehend a being, it is necessary to study it also in this aspect of "non-being." Finally, the text highlights the traditional metaphysical bias toward the visual and the "seen," contrasting it with a temporal orientation toward listening. This approach suggests an ontology that accounts for the processual and event-like nature of reality, moving beyond mere actual presence.
