This paper synthesizes Parts 3 and 4 and extends their implications to epistemology and ethics. We propose a framework termed “materialized idealism”: matter exists eternally as substance, while observers (through measurement basis selection) determine which properties become actualized. We argue that “observer is primary” means: not metaphysically (matter alone is substance), not causally (matter exists independently), but actualizing-wise (measurement basis selection determines which properties become real). This resolves tensions between observer-dependent quantum mechanics and classical physics, and provides rigorous grounding for Nietzsche’s perspectivism without collapsing into relativism. Key contributions: • A coherent interpretation of quantum measurement and classical emergence • Grounding for free will and moral agency within causal structure • Rigorous foundation for perspectivism avoiding both relativism and absolutism • Integration of quantum mechanics, thermodynamics, phenomenology, and ethics • Historical vindication of ancient philosophy and reinterpretation of modern thinkers
