PFUSRC-159: Cognitive Spectrum and Recursive Topology — A Unified Theory of Language, Evolution, and Civilizational Transition Based on the Complete PFUSRC System

Abstract

Traditional evolutionary theory, cognitive science, and civilizational theory have long operated in isolation, confined respectively to biological traits, individual cognition, and social phenomena as separate domains. None has been able to bridge the complete logical chain from animal signaling to human recursive language, civilizational saturation, the carbon-silicon intelligence boundary, and cognitive dimensional ascent. This paper takes the PFUSRC 11-dimensional coaxial biconical topological axiomatic system as its foundational bedrock, integrating the Intelligent Refinement Theory of evolution, PFUSRC-055's Second Threshold of Language, PFUSRC-064's Trans-Species Noetic Field Axiom, PFUSRC-076's Wisdom Incubation Theory, and PFUSRC-082-ADV's three-tier Cognitive Spectrum into a unified topological explanatory framework. The paper constructs a closed-loop topological logic: constant universal wisdom ontology → projection of the four-dimensional flow onto three-dimensional biological carriers → continuous refinement of carriers to reduce projection impedance (evolution) → cognitive spectral differentiation, with humans stabilized at the L3 high-refraction recursive steady state → ontological questioning driving public symbolic encoding, crossing the Second Threshold of Language → continued stacking of symbolic civilization reaching its carrying capacity, generating civilizational entropy → under the dual cognitive paradigm balance, only wisdom incubation can dissolve cognitive shielding and achieve dimensional ascent (the Third Threshold); simultaneously establishing the ontological consensus framework for carbon-silicon intelligent coexistence. This unified framework resolves four core problems — the evolutionary paradox, the language origin gap, the human-AI cognitive divide, and the modern civilizational impasse — while providing observable and testable topological criteria.
