The Ontological Necessity of the Monistic Entity: Establishing the Foundations of a Singular Reality

Abstract This paper introduces the monistic entity (ME) as the necessary and eternal substrate of all existence. Considering the accelerating developments in artificial intelligence, particularly large language models—a veridical understanding of reality’s foundation is essential for coherent inquiry into nature, mind, and consciousness. ME is first contrasted with historical monistic philosophies, not to refute them, but to reveal its structural inevitability as the foundational architecture of being. A formal ontological argument, grounded in five axioms and culminating in a theorem, demonstrates that ME is singular, indivisible, and necessarily real. From this argument, a precise definition of ME is distilled. The paper concludes with a glossary of terms to support reader comprehension and establish a shared vocabulary for future work.
