Chapter 91: The Kant-τ Correspondence

Kant completed two pillars of reason at full resolution: the empirical pillar (Critique of Pure Reason) and the practical pillar (Critique of Practical Reason). The third pillar—the diagrammatic bridge between knowing and acting—is what Kant attempted in the Critique of Judgment but could not formalize. This chapter maps Kant’s critical architecture onto the four-register model of τ: CPR to the empirical register ℝeg_E, CPrR to the practical register ℝeg_P, CJ to the diagrammatic register ℝeg_D, and the postulates of practical reason to the commitment register ℝeg_C. The mapping reveals that Kant left a precisely shaped socket—the diagrammatic bridge—unspoken rather than filling it with unearned closure. Three methodological rules extracted from Kant’s discipline govern how the socket must eventually be filled.
