Separation of First Principle

This paper proposes a radical philosophical thesis: that the original structure of reality is not unity but separation. Against the dominant Western metaphysical tradition — from Parmenides and Plato through Hegel and Heidegger — which assumes unity as the primordial fact and treats multiplicity as secondary or derivative, the author argues that an absolute, original separation precedes all ontology, epistemology, and logic. Called the "Separation of Principle," this primordial duality is not a separation between two pre-existing things but the foundational structure making being itself possible. The paper traces the manifestations of this separation across language (the impossibility of expressing two worlds in a single statement), logic (the impossibility of a single governing logic), science (the structural necessity of dual units of measurement), and ontology (the irreducible duality of Act and Potency). It engages critically with Derrida, Deleuze, Levinas, Heidegger, and Husserl, with Eastern traditions including Taoism and Advaita Vedanta, and with Islamic mysticism through Ibn ʿArabī's concepts of the barzakh and the fixed archetypes. A concluding chapter examines major philosophical systems — Aristotle, Mullā Ṣadrā, Spinoza, and Ibn ʿArabī — as failed attempts to bridge the original gap between the Two Worlds.
