This paper extends the Self-as-an-End theoretical framework from the law of causality (4D) to the law of cognition (8D), demonstrating four chisel-construct cycles: the law of replication (5D), the law of behavior (6D), the law of perception (7D), and the law of cognition (8D). Each layer follows the same unifying principle: negation operates within the accumulated transcendental foundation, and the only self-consistent result is that layer's construct. The paper establishes that "operating within jurisdiction" is not the same as "being reducible to," providing a structural critique of reductionism. The 8D endpoint — self-consciousness becoming aware of its own death — is identified as the dividing line between nature (1D-8D) and freedom (9D and above), precisely locating Kant's nature/freedom dichotomy within the framework.
