Scientifica Metaphysica: A Critique of Pure Appearance

This book derives and applies a predomain condition — H > K (holding exceeds dissolution) — that must hold for anything to appear at all. The argument is transcendental and self-securing: any denial of H > K from within any domain of inquiry instantiates the condition it denies. Seven structural operators co-necessary with H > K are derived and mapped to physical, logical, and mathematical instantiations. The framework crosses Hume's is/ought and fact/value divides by generating quantitative predictions from purely structural premises. The decoherence time of the FMO light-harvesting complex is predicted at τ ≈ 61 femtoseconds with zero free parameters (2% agreement with experiment). A structural ceiling β ≤ 1/2 on phase-transition critical exponents is confirmed across eight systems. The dark energy equation of state attractor w* = −5/7 ≈ −0.714 falls within 0.67 standard deviations of the 2025 DESI measurement; the phantom bound w > −1 constitutes a falsifiable theorem testable by Euclid 2027. Structural ethics (three principles, two forms of evil, derivation of agape) and engagement with Kant, Meillassoux, Ladyman/Ross, Gödel/Penrose, and Chalmers complete the framework.
