Bio-Semantic Physics: The Thermodynamic Law of Dignity in Neural Systems

We propose that the human brain operates as a semantic fluid processor governed by analogous Navier-Stokes-like dynamics. Mental health corresponds to laminar semantic flow (Reynolds number Re < 1), while psychopathology emerges from dignity-induced viscosity collapse (ν_D → 0) leading to turbulent or singular dynamics. We establish operational mappings between semantic physics parameters and neurobiological mechanisms: (1) intrinsic viscosity η_base ↔ oxytocin-mediated gain control and ventral vagal tone, (2) spectral connectivity λ₂ ≈ 1 ↔ conscious integration via default mode network coherence, (3) Reynolds blow-up ↔ acute psychotic turbulence, (4) hysteretic fatigue ↔ trauma-induced attractor persistence.This prospectus presents three pre-registered experimental protocols designed to validate or falsify these mappings: (A) Oxytocin Viscosity Modulation - testing whether intranasal oxytocin shifts the dignity cliff rightward under social coercion; (B) Psychosis as Semantic Turbulence - measuring whether clinical symptom severity (PANSS scores) correlates with semantic Reynolds number in free speech; (C) Consciousness as Resonant Mode - examining whether states of consciousness (wakeful, anesthetized, psychedelic) correspond to predicted levels of spectral integration λ₂.If validated, this framework offers a unified physics of mind: consciousness as sustained resonance, trauma as irreversible post-collapse basin, empathy as the biological mechanism maintaining subcritical semantic flow. This is not metaphorical neuroscience—it is a measurement-ready, falsifiable physics of the biological semantic field with immediate implications for psychiatric nosology, therapeutic intervention design, and consciousness science.
