A Perspective Shift in Quantum Mechanics: From Physical Law to Mind-Matter Linkage An Epistemological Reconstruction Based on the Mind-Matter Unity Hypothesis

The mathematical formalism of quantum mechanics has achieved undeniable success over the past century, yet its interpretation remains persistently divided. The Copenhagen, Many-Worlds, and Quantum Bayesian interpretations—none can coherently address the recurring "observer participation" issue in quantum phenomena without introducing additional ad hoc assumptions. This paper argues that this division does not stem from deficiencies in mathematical formalism, but from a deeper paradigmatic presupposition: that quantum mechanics is tacitly regarded as a theory of "matter itself." This paper proposes a different perspective: quantum mechanics is not a theory describing the properties of matter itself, but a theory describing the rules by which information is translated from a global potential state to a local manifest state when material systems couple with cognitive systems—what this paper terms the "Mind-Matter Linkage." Based on the axiom of "Mind-Matter Unity," this paper defines three layers of function (Ontological Function, Differentiation Function, Manifestation Function), and repositions quantum mechanics as the mathematical formal system of translation rules between the Differentiation Function and the Manifestation Function. From this axiom, this paper successively derives five core phenomena that require ad hoc assumptions within the matter-only framework—the delayed-choice experiment, the quantum eraser experiment, quantum entanglement, the quantum Zeno effect, and the "Hard Problem" of consciousness—demonstrating how a single set of premises naturally yields these phenomena without the need for additional assumptions for each individual phenomenon. Comparative analysis shows that, in the specific dimension of "number of assumptions required to explain the fivefold dilemma," the framework proposed here exhibits structural advantages, though these advantages remain at the level of explanatory power and have not yet been extended to mathematical formalization or predictive power. This paper does not deny the reality of matter, does not modify the mathematical formalism of quantum mechanics, and does not replace existing interpretations, but rather offers a supplementary perspectival shift at the epistemological level.
