Ontology-Epistemology

Traditional philosophy falls into the dualistic separation of ontology and epistemology, with various paradigms containing illegal meta-presuppositions or self-referential paradoxes that fail to form a deductively closed framework. This paper establishes a self-consistent axiomatic first philosophy system by taking "Existence must be knowable" as the sole initial axiom in accordance with the principle of minimization. Through pure formal deduction, it derives the determinacy and distinguishability of cognitive objects, further deduces the laws of formal logic and the discrete structure of existence, refutes the legitimacy of non-existence and nothingness, exposes the cognitive illusion of "symbol equals existence," and criticizes the foundational flaws of traditional philosophy. The framework realizes the unity of ontology and epistemology, provides an original solution to the dilemmas of contemporary philosophy, and offers a unified philosophical support for mathematics, physics, cognitive science and other disciplines, with cross-domain universality and explanatory power.
