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.

Lea Ypi在《理性的架构》中指出，康德在为理性的系统统一奠定基础的尝试中最终失败了，因为在第一个批判中缺乏自由的实践领域。我的目的是通过以下方式对康德所谓的失败进行更细致的解读：（1）区分《先验辩证法》附录中思想的图式和《建筑学》中纯粹理性的图式。（2）我认为，虽然第一个批判中没有确立自由的实践领域，但经典和建筑学确实解释了它的条件：理性的实际运用及其与理论的统一。我指出，虽然（3）观念的图式解释了理解认知的唯一系统安排以及观念和理想的调节作用，但在建筑学中，（4）纯粹理性的图式反而具有更普遍的意义。系统性是理性构建其自身统一整体及其两种合法用途之间统一性的前进方式。
