Did Nietzsche bring about the fulfillment of metaphysics, as Heidegger maintains? Answering this question requires following Heidegger's reading of Nietzsche up to the point where it al-lows itself to be put into question, opening itself to a deeper interpretation. If there is a mo-ment (Augenblick) in which the thought of the eternal return emerges as an event within the cycle of repetitions, the discontinuity it introduces prevents us from falling into the everlasting recurrence of an undifferentiated sameness.
This discontinuity brings us to a moment of deci-sion and responsibility to the world in which we find ourselves, opening the way for a recon-sideration of what Heidegger calls the epoch of technology. Following two key Heideggerian concepts - presence and subjectivity - to their Latin and Greek origins brings to light the dif-ference between the being of beings and the dwelling of the "is" and leads to an interpretation of the eternal return that locates Nietzsche's thought beyond the closure of metaphysics.
