The article attempts to analyze the existential idea of the innate conflict between me, a human being, and the world, set in the psychoanalytical context of the primary separation between me — a tragic emptiness — and the other who is introduced to me in the form of the mother's womb. (O) — from the French l’autre (the other) — literally marks the object-cause of my desire, l’objet a that escapes me radically (Latin radix meaning root), at the moment of me being born and separated from the mother. In this context, the radical separation made present in the primordial cut of the (O) is the very secret of both death and language.
