This article examines Heidegger’s thoughts on Nietzsche’s philosophy of eternal return and the self-overcoming power of thinking. Scholarly commentators argue that Heidegger’s interpretation of Nietzsche reduces the open possibilities of thinking about temporality, becoming and difference into a rigid metaphysical framework of being as a whole. However, a close reading of Heidegger’s thoughts on the eternal recurrence shows that his interpretive attempt to disclose the metaphysical ground of Nietzsche’s thinking reveals a deeper, dynamic dimension of Nietzsche’s recurrent efforts of self-overcoming. (...) In this light, I argue that Heidegger’s interpretive thinking intends to uncover an empowering ground of Nietzsche’s philosophical struggle to overcome the metaphysical limit of human thoughts facing the lively unity of difference. For Heidegger, Nietzsche’s thinking of the eternal recurrence is not to suggest a metaphysical doctrine of being but to grasp a determinate basis of one’s own existence, repeatedly seeking the greater possibility of being with others.
