Medicine After Stabilization: A Generative Ontology of Health, Disease, Aging, and Death through Universal Phase Crystallization Theory (UPCT) -Toward a Resilience-Centered Medical Paradigm-

Modern medicine has mastered stabilization. Yet the greatest health challenges today arise not from instability, but from loss of generative renewal. This paper proposes a fundamental reconfiguration of medicine through Universal Phase Crystallization Theory (UPCT). Health is redefined as the capacity to reopen generative circulation after stabilization. Medicine thus shifts from repair of structure to cultivation of life’s ongoing generativity. Highlights • Proposes the first full generative ontology of medicine based on UPCT• Redefines health as reopening capacity rather than stable equilibrium• Reinterprets disease and aging as interruptions of generative circulation• Integrates neuroplasticity, microbiome, epigenetics, and regenerative medicine into one framework• Establishes a resilience-centered paradigm linking medicine and civilizational renewal Extended Summary Modern medicine has achieved extraordinary success by restoring stability within biological systems. However, chronic disease, aging, and mental health conditions increasingly reveal the limits of a stabilization-centered paradigm. These conditions persist despite intervention because they involve diminished generative capacity rather than simple instability. This paper introduces Universal Phase Crystallization Theory (UPCT) as a generative ontology of life. UPCT conceptualizes living systems as dynamic circulations among generativity (Φ), relational mediation (G), and stabilization (S). Health emerges when this circulation remains open and recoverable, particularly through reopening capacity (ρ). Disease and aging are redefined as local or cumulative interruptions of generative circulation. Symptoms represent stagnation rather than merely instability. Aging corresponds to gradual contraction of adaptive basin width, reflecting declining recovery dynamics across biological systems. The framework integrates recent advances in neuroplasticity, microbiome research, epigenetics, and regenerative medicine, demonstrating convergence toward a resilience-centered understanding of health. Medicine is reconceptualized as the cultivation of reopening capacity rather than the maintenance of fixed states. This generative reconfiguration aligns individual health with broader civilizational resilience. By restoring generative circulation at biological and social levels, medicine can move beyond repair toward sustaining the ongoing vitality of life itself. The paper establishes a conceptual foundation for future empirical research and clinical transformation. Author’s Related Works Ohumi, K. (2025).
