This text reflects on the philosophical concept of the unity of the world as a totality. Traditional monism often assumes that this unity must be grounded within the world itself, through something with an objective or substantial character. The author challenges this established notion and raises the question of whether the source of unity could lie outside the framework of all "being." He proposes a provocative thesis: the foundation of the world might not be a being, but rather "non-being" that is yet to "come." This external unity is then linked to the concept of the "true future." The reflection opens space for redefining the ontological foundations of the world, where unity is not a static ground of the past or present, but a dynamic horizon constituting the world from the outside. Through this approach, the author distinguishes his view from classical metaphysical substantialism, seeking new ways to grasp the totality of reality through temporality and transcendence.
