Based on the axiomatic foundation of the three Zhu-Liang Truth Theorems (Functor Theorem, Metabolism Theorem, Prime Mover Theorem), this paper proposes and systematically elaborates the unified meta-definition of all disciplines grounded in the Zhu-Liang Prime Mover Theorem. Starting from the undeniable meta-facts \ (F₁\) (existence of differences) and \ (F₂\) (determinacy of correlations), with the Prime Mover \ (F = (T₀, M) \) as the sole meta-source, meta-dynamics, and meta-law, this definition unifies all disciplines—including physics, chemistry, biology, cognitive science, mathematics, computer science, social science, and philosophy—as necessary projections of the truth metabolic system at different recursive levels \ (n\). We prove that the essence of any discipline is the study of \ (F\) embodied at a specific recursive depth, with differences between disciplines arising solely from variations in recursive level \ (n\), while their unity derives from the uniqueness of \ (F\). This meta-definition terminates the ontological fragmentation of disciplines and establishes the meta-theoretical foundation for a unified science. The conclusion is absolute and immutable.
