This text provides an in-depth analysis of the concept of presence in response to Heidegger's critique of ancient Greek thought. The author re-evaluates the thesis of "understanding being from presence," arguing that the flaw in Greek ontology lies not in the focus on presence itself, but in its static, point-like conception. True presence is defined here as an event-based unification of the current phase with the whole of a process, which, through consciousness and reflection, integrates non-present phases. Significant attention is given to the role of the Greek Logos, which transformed the mythical orientation toward primordial origins into an "eternal now" (aeternum nunc). This shift is interpreted as a necessary attempt to strip the past of its paralyzing dominance. Finally, the author contrasts Greek temporality with the tradition of ancient Israel, which introduces a radical orientation toward the future and a reality that "is not." The work thus illuminates the transition from objectifying presence to historical openness toward the future, representing a fundamental moment in the understanding of human temporality.
