 Just as understanding and sensibility are subserved by the bottom-up cognitive processing of the imagination, so in turn they are also superserved by the top-down cognitive processing of the faculty of “reason” (Vernunft), which produces logical inferences, carries out pragmatic or moral choices and decisions, a.k.a. “practical judgments”), imposes coherence and consistency on all sorts of cognitions, and above all recognizes and implements strongly modal and categorically normative concepts such as necessary truth and unconditional obligation, in the form of lawlike “principles” (Principien, Grundsätze) (A299–304/B355–361, A800–804/B828–832).
