This paper explores the philosophical interpretation of the concepts LOGOS and PHYSIS based on Heraclitus's fragments and Heidegger’s etymological analysis. Heidegger interprets the Greek verb LEGEIN as "gathering" or "selecting," implying not a mere accumulation of things, but their unification into a meaningful whole. Without Logos, the world would be a random pile of objects; thus, Logos serves as the guarantor of the cosmic order. The text examines the mutual interdependence between Logos and Physis. While Physis represents the process of birth and growth, Logos acts within this process as a principle of unity and selection. The author highlights a paradox: for something to be selected, it must first be born (Physis precedes Logos), yet for that which is born to constitute a functional unity, Logos must assist at its birth. The abstract concludes by calling for a deeper investigation into the relationship between the unchanging Logos and the dynamic nature of Physis, which inherently involves principles of change, development, and governance.
