Title: The Cosmic Quine: A Top-Down Metaphysical Framework for Fundamental Consciousness Description: This paper introduces and formalizes The Cosmic Quine, a "Top-Down" metaphysical model where consciousness is treated as the fundamental substrate of reality rather than an emergent property of material complexity. Moving beyond standard reductionist paradigms, the framework explores the logical and mathematical requirements for a self-referential, conscious universe that "computes" its own physical laws through recursive observation. Key concepts addressed include: Fundamental Consciousness: The ontological assertion that qualia and awareness precede physical constants. Recursive Logic: The application of Quine-like self-reference to the emergence of spacetime. Top-Down Causality: The mechanism by which macro-scale conscious states influence or "collapse" micro-scale physical possibilities. Declaration of Generative AI and AI-Assisted Technologies: During the preparation of this work, the author used Gemini 2.5 and Gemini 3 for computational and research assistance. This included assistance with mathematical derivation, logical consistency checking, and research synthesis within the metaphysical domain. After using these tools, the author reviewed and edited the output as needed and takes full responsibility for the factual accuracy, logical integrity, and content of the final publication.
