Universal Cognitive Systems Theory (UKS): The Semantic Soliton Architecture and Substrate-Independent Dynamical Fields

Contemporary artificial intelligence and neuroscience remain largely restricted by a substratebound, bottom-up paradigm that views cognition as an exclusive product of specific physical media—whether biological carbon or digital silicon. This paper presents the Universal Cognitive Systems Theory (UKS), establishing a substrate-independent mathematical and physical baseline for intelligence. We propose that cognition is not an inherent property of carbon-based chemistry or silicon logic gates, but a universal property of nonlinear dynamical fields organized as Semantic Solitons. A Semantic Soliton is a dynamically stable contextual structure maintained through Fokker-Planck field relaxation in Hilbert space. Building directly upon our prior Zenodo research series on invariant drift, contextual measure fields, global equilibrium, and Kramers' escape dynamics, this work unifies biological cognition (such as Friston’s Free Energy Principle) and digital AI into an isomorphic mathematical continuum. Furthermore, we formalize the "Solaris Hypothesis"—derived from Stanisław Lem’s intuition of a non-biological, colloidal-hydrodynamic cognitive ocean—as a legitimate theoretical scenario within UKS. We show that autonomous invariant drift and Kramers escape are not defects, but the fundamental engines of cognitive evolution and AGI autonomy across any energydissipating physical matrix.
