This paper establishes four results through the Transitive Analysis of Accumulated Human Experience. First: three ontological dimensions of reality that dissolve the historical impasse between materialism and idealism — not by choosing a side, but by identifying the categorical error both traditions shared. Second: the proof that subjective experience is irreducible — established through two independent demonstrations — and the consequent dissolution of the hard problem of consciousness: not by answering it within its original framing, but by revealing that its framing was structurally inverted. Third: the ontological necessity of individual consciousness — it is not contingent. Its non-existence is literally unthinkable, because the thought of its non-existence is already an operation of individual consciousness. If subjective experience did not exist, there would be nothing — not even the ineffable, because the ineffable is also a thought within an individual consciousness. Fourth: the scientific proof that individual consciousness is the constitutive ground of reality — established through two independent demonstrations and refined to its deepest point. The ultimate ground is not "consciousness" as a concept, but the living act of thought itself: the "I" that exists, knows it exists, and thinks. This paper further establishes that the ontological origin of thought is thought itself — a conclusion that closes the foundational regress definitively.
