This text explores the ontological and etymological definition of the term existence, derived from the Latin ex-stare, meaning "to stand out." The author argues that existence can only be attributed to beings capable of "standing outside of themselves." This movement is not understood as a mere abandonment of oneself or as an active process of transitioning from the future into the past. Instead, existence is interpreted as a specific inclination or "leaning out" into the future, which does not take the form of an active performance or deed. The central conclusion is that the subject of existence cannot be a being in the ordinary sense, but exclusively a being-subject. Only a subject is capable of this distance from itself, allowing it to relate to itself not as something closed and past, but as something actually present. This distance and subsequent return to oneself form the fundamental structure of subjectivity and true existence, thereby distinguishing it from the mere persistence of objects in time.
