Beyond Essence: Ontological Instability as the Foundational Axiom for Post-Essentialist Metaphysics

This presentation articulates a foundational shift in metaphysics from traditional essentialism to a post-essentialist framework. It argues that the classical model of reality, composed of substances with fixed essences, is logically untenable, leading to intractable problems concerning change, individuation, and emergence. In its place, the presentation posits Ontological Instability as a foundational axiom, asserting that being is inherently and necessarily defined by dynamic processes rather than static properties. This new paradigm is developed through five core concepts: Fluctuational Entities, Dynamic Assemblages, Metamorphic Causation, Ontological Uncertainty Relations, and a Rhizomatic Ontology. Together, these concepts form a coherent system that replaces traditional notions of substance, identity, and causation with a process-oriented, relational, and creative model of reality. The presentation concludes by demonstrating the superior explanatory power of this framework, its necessity arising from the internal contradictions of essentialism, and its profound implications for addressing contemporary challenges in fields ranging from climate science to social theory.
