This book argues that every genuine unification in physics—from special relativity (1905) to electroweak theory (1967)—began not with mathematical elegance, but with a *philosophical cut*: the courageous questioning of a then-“self-evident” ontological presupposition (absolute simultaneity, independent particles, symmetric vacuum, etc.). In contrast, the period from 1995 to 2025 has seen a systematic retreat from such ontological inquiry, replaced by a faith in mathematical consistency, landscape multiplicity, and effective-field-theoretic fitting. The result is a “unification impotence”: five major programs (string theory, LQG, AdS/CFT, asymptotic safety, multiverse) have produced no unique, testable prediction in three decades, despite unprecedented funding and talent. Through a historical reconstruction of the four 20th-century unifications and a critical analysis of contemporary trends, the book diagnoses a collective *ontological silence* as the root cause. It then examines three emerging approaches—Orch-OR, configurational entropy thermodynamics, and Energy Quantum Theory (EQT)—that explicitly reintegrate philosophical grounding with falsifiable physics. The work concludes by proposing a methodological renewal: physics must return to its Einstein–Bohr–Weinberg tradition, where **philosophy is not decoration, but the art of asking the right ontological questions that lead to empirical consequences**. Crucially, this is not an attack on mathematics, but on *mathematics without ontology*. The book advocates for a “phenomenon–mechanism–mathematics” trinity, where formalism serves explanatory depth, not just predictive curve-fitting.
