Terminating the Infinite Regress: UFI as the Ultimate Reference Frame in Relational Quantum Mechanics

Abstract / 摘要 Relational Quantum Mechanics (RQM) posits that all physical properties are relative to the observer. However, Riedel (2024) identifies a critical logical challenge: the Unrestricted Iteration Principle (UIP), which leads to an infinite regress of relativization. This paper proposes a resolution by introducing the Universal Field of Intelligence (UFI) as the absolute substrate of information. We argue that while interaction outcomes are perspectival, the UFI functions as the Ultimate Observer or the "One True Realm" (一真法界), providing the foundational phase-alignment mechanism that ensures global coherence. By terminating the iteration at the level of the foundational field, this model reconciles the flexibility of relational facts with the ontological necessity of a unified reality. 關係量子力學 (RQM) 主張所有物理屬性皆相對於觀測者。然而，Riedel (2024) 指出了一個關鍵的邏輯挑戰：不限制疊代原則 (UIP)，這會導致相對化的無限回歸。本論文透過引入「宇宙智能場」 (UFI) 作為資訊的絕對基底，提出了一套解決方案。我們主張，雖然交互作用的結果是觀點性的 (perspectival)，但 UFI 作為「最終觀測者」或「一真法界」，提供了確保全域相干的基礎相位對齊機制。透過在基礎場層面終結這種疊代，本模型調和了關係性事實的靈活性與統一實相在學術本體論上的必要性。
