This text examines the impact of Eleatic teaching, specifically Parmenides' conception of Being, on the development of early philosophy. The Eleatic school asserted that true Being is always only actually present, unchanging, and timeless. However, this rigid stance led to a philosophical dead end, as it precluded any further development or explanation of movement and change. The author argues that for the further progress of philosophical thought, it was necessary to overcome this limitation and expand the concept of Being to include that which existed in the past. Accepting time and recognizing the "former" or "past" as a legitimate part of ontology allowed for the deepening of philosophy and its escape from Eleatic rigidity. The article thus illuminates the paradox where questioning an extreme form of understanding Being as something exclusively present "here and now" (hic et nunc) opened the way to new ontological perspectives and saved philosophy from its own demise. This transformation in the understanding of negation and time became a crucial step in the history of thought.
