Youjue Physiology: An Outline proposes a paradigm revolution in mind and life sciences, shifting focus from abstract speculation about "consciousness" to the living, self-constructing "Youjue System"—life itself as a continuously operating Sensation-Behavior Cycle. This interdisciplinary work, rooted in the intellectual lineage of Robert Whytte, Ivan Sechenov, and Gerald Edelman, introduces a unified meta-framework that reinterprets mental phenomena as emergent properties of life’s fundamental drive to maintain homeostasis through dynamic cycles of sensation and action. The book’s core innovation lies in its Three-Dimensional Dynamic Taxonomy of Youjue Sensation, which maps the complete mental spectrum across evolutionary strata (Vital, Social, Noetic) and three basic life tensions (Defensive, Offensive, Friendly). This framework systematically parses experiences ranging from primal pain and hunger to belonging, status, intellectual curiosity, and meaning-seeking. All levels of "unwellness" and growth originate from Expectancy-Sensation Mismatch—the conflict between immediate sensation and innate or learned expectancy—which drives learning and adaptation. Crucially, The Outline reveals a universal generative logic—Resonance-Evaluation-Consolidation—that operates isomorphically across all scales: from neuronal cluster formation via Neural Darwinism, to social cohesion through shared Sensation-Behavior patterns, to cultural propagation of Thought Memes. This logic demonstrates how complex structures emerge when systems achieve pattern resonance through Reentry and selectively stabilize effective Sensation-Behavior cycles via positive value evaluation. The work thoroughly reconstructs traditional concepts—Need, Emotion, Consciousness, Self, and Will—in pure "Youjue" language, anchoring them in the dynamic dialogue between expectation and reality. It culminates in a vision of the Youjue Person: a lucid, agentic, and warm existence that self-directs through intrinsic dynamic orientation, moving beyond Descartes' isolated "I think, therefore I am" to a resonant "I feel, therefore we are." Youjue Physiology is not merely a theoretical revolution but a transformation of worldview, enabling science to embrace complete life and providing a solid framework for understanding mind, self, and social cognition—from the "Youjue Person" to the "Youjue Ecology" of civilizational futures.
