The aim of this article is to explore the ontological difference within Parmenides’s poem “Peri physeōs,” with a specific focus on line B 2.3, which reads: “exists, and it is not possible not to exist” (estin te kai hōs ouk esti mē einai). By interpreting “ouk esti” as a negative judgment and “mē einai” as a negative predication, I argue that this line already conceals the essence of the ontological difference, insofar as being is not an entity, and entities are (...) not-being. This interpretation draws on Plato’s notion of negation and difference as discussed in "The Sophist," as well as on Kantian infinite judgment. The distinction between these two negations enables the development of the concept of a meontological difference between“non-being” and “non-entities,” which lies at the core of the ontological difference between being and entities, and also illuminates Heidegger’s pairing of Ereignis and Enteignis. Additionally, I argue that Heidegger’s interpretation of Heraclitus in light of truth as alethēia relies on a similar double-negativity. Finally, I show the illuminating potential of examining the ontological difference in Parmenides by analyzing Heidegger’s 1949 preface to the third edition of the treatise “On the Essence of Ground” (1929).

This paper explores the deep philosophical affinities between Martin Heidegger and Friedrich Nietzsche, focusing on their shared understanding of the Apollonian and Dionysian dichotomy and its implications for the essence of human existence. The analysis begins by examining Nietzsche's concept of the unity of the Apollonian and Dionysian as a fundamental aspect of human identity, despite Nietzsche's own unawareness of its metaphysical significance. Heidegger, in turn, recognizes this insight as an epochal breakthrough in Nietzsche's thought, surpassing the boundaries of traditional (...) meta-physics. The discussion further explores the role of Hölderlin as a crucial figure in both Nietzsche's and Heidegger's philosophical trajectories. It argues that in the co-appropriation of the Apollonian and Dionysian and the concept of Ereignis (the Event), both philosophers reveal a profound engagement with the interplay of foundation and abyss. This interplay, according to Heidegger, constitutes the historical-epochal opening of being and provides a perspective for understanding the essence of Dasein as the Ek-sistence (existential being). The paper challenges Heidegger's reductionist interpretation of Nietzsche as merely the completion of metaphysics and suggests a closer affinity between Nietzsche and Hölderlin. It concludes by emphasizing the transformative potential of embracing the interplay of the Apollonian and Dionysian and the reevaluation of human essence based on existence, which enables a new understanding of the world and its inherent mysteries.
