Contemporary mind science has reached an impasse over the "hard prob-lem" of consciousness, facing the predicament of data-rich yet theoreti-cally fragmented. This paper proposes the "Generative Theory of the Sensation-Behavior Cycle," achieving a fundamental paradigm shift: from abstract speculation about "consciousness" to the study of life itself as a generative process of the "Youjue System." The theory takes the Sensation-Behavior Cycle as its basic unit and Value-Dependent Selec-tion as its core mechanism, constructing the Three-Dimensional Dy-namic Taxonomy of Youjue Sensation to systematically explicate the emergent path of mind from the Vital Stratum, Social Stratum to Noet-ic Stratum, and revealing the unified generative logic running through all strata ── "Resonance-Evaluation-Consolidation." Based on this, the paper thoroughly reconstructs core concepts such as memory, cogni-tion, need, emotion, consciousness, self, and will from a generativist per-spective, and creatively reinterprets classic research. More importantly, the paper explicitly elaborates on the methodological revolution of "Life Empiricism" ── grounding itself in irreducible first-person facts, tak-ing subject-internalization and change as the criterion of validation, and regarding traditional scientific data as corroborative traces of the subject's state. This theory aims to provide a powerful meta-theoretical framework for life science, achieving seamless interpretation from neural activity to civilizational structure, and opening new integrated paths for mind re-search.
