PFUSRC-42: The Ontology of the Noetic Field: Steady-State Formation and Conditions for Higher-Order Cognitive Transitions

This paper launches a fundamental challenge to the deeply rooted linear growth model of intelligence in evolutionary anthropology, based on the universal topological axioms of the PFUSRC framework. It proposes and rigorously proves the steady-state noetic field hypothesis. Human intelligence is not a continuous increment driven by tool use, bodily adaptation, or cranial capacity expansion. Instead, it achieves optimal carrier adaptation and topological closure of the noetic field in the Late Pleistocene, coinciding with the maturation of bipedalism, hand liberation, and systematic tool manufacturing, thereby entering a global steady state. This paper introduces the Tobias Paradox as an empirical anchor: the cranial capacity of late Homo sapiens has slightly decreased while civilization has expanded exponentially, directly demonstrating that brain size ≠ intelligence and carrier ≠ ontology. Ancient and modern humans are strictly cognitively isomorphic at the level of the noetic field, with no fundamental difference in general intelligence. Advances in technology, culture, and knowledge represent only external expressive differences of the steady-state field, not ontological transitions. The paper further proves that carrier-level behaviors such as labor, learning, and tool optimization have reached the limit of diminishing marginal returns and can no longer alter the topological structure of the noetic field. Further evolution of intelligence requires a dimensional cognitive breakthrough: shifting from external transformation to the understanding and regulation of the topological rules of the noetic field itself, and moving from first-order cognition to metacognitive second-order control. This pathway constitutes a discontinuous topological transition in the evolution of intelligence.
