Ultimate Resolution of Hume’s Causality Problem: A Logical Proof Based on Cognitive Succession Ontology

Hume’s causality problem, proposed in A Treatise of Human Nature, is one of the most subversive intellectual challenges in the history of Western philosophy. Through rigorous empiricist analysis, Hume proved that what humans call "causal necessity" is essentially nothing more than a habitual association of "constant conjunction" between succession sequence nodes, with no objective or logical necessity. This conclusion not only destroyed the traditional metaphysical view of causality but also shook the legitimate foundation of all scientific knowledge. For more than two hundred years, solutions such as Kant’s a priori category theory and modern scientific instrumentalism have failed to thoroughly respond to Hume’s skepticism. Based on Cognitive Succession Ontology, starting from the unfalsifiable first principle that "the essence of cognition is succession", this paper rigorously proves through logical deduction that succession is the ultimate meta-rule governing all existence and cognition. Causal necessity is neither a subjective habit nor an a priori category, but a logical necessity of being itself. This theory fundamentally resolves Hume’s problems of causal necessity and inductive legitimacy, providing a solid ontological foundation for human scientific knowledge.
