The Schematism of Reason from the Dialectic to the Architectonic

Abstract

Abstract In The Architectonic of Reason Lea Ypi argues that Kant ultimately fails in his attempt at grounding the systematic unity of reason because of the lack of the practical domain of freedom in the first Critique . I aim to advance a more nuanced reading of Kant’s alleged failure by (1) distinguishing between the schematism of the ideas in the Appendix to the Transcendental Dialectic and the schematism of pure reason in the Architectonic. (2) I suggest that, while the practical domain of freedom is not established in the first Critique , the Canon and the Architectonic do account for its condition: the practical employment of reason and its unity with the theoretical. I point out that while (3) the schematism of the ideas accounts for the sole systematic arrangement of the understanding’s cognitions and the regulative role of the ideas and the ideal, in the Architectonic, (4) the schematism of pure reason instead bears more generally on systematicity as reason’s way of proceeding in framing its own unitary whole and the unity between its two lawful employments.
