 In contrast to both Rationalists and Empiricists, who hold that the human mind has only one basic cognitive faculty—reason or sense perception, respectively—Kant is a cognitive-faculty dualist who holds that the human mind has two basic cognitive faculties: (i) the “understanding” (Verstand), the faculty of concepts, thought, and discursivity, and (ii) the “sensibility” (Sinnlichkeit), the faculty of intuitions/non-conceptual cognitions, sense perception, and mental imagery (A51/B75). The essential difference between the faculties of understanding and sensibility, and correspondingly the essential difference between concepts and intuitions (A50–52/B74–76), as distinct kinds of cognition, is a fundamental commitment of Kant’s theory of cognition generally and of his theory of judgment more specifically. Concepts are at once (a) general representations having the logical form of universality (9: 91), (b) discursive representations expressing pure logical forms and falling under pure logical laws (A68–70/B92–94, A239/B298), (c) complex intensions ranging over “comprehensions” (Umfangen) that contain all actual and possible objects falling under those intensions, as well as other narrower comprehensions (9: 95–96), (d) mediate or indirect (i.e., attributive or descriptive) representations of individual objects (A320/B376–377), (e) rules for classifying and organizing perceptions of objects (A106), and (f) “reflected” representations expressing the higher-order unity of rational self-consciousness, a.k.a. “apperception” (B133 and 133n.). Intuitions by contrast are conscious object-directed representations that are (1) singular (A320/B377) (9: 91), (2) sense-related (A19/B33, A51/B75), (3) object-dependent (B72) (4: 281), (4) immediate, or directly referential (A90–91/B122–123, B132, B145), and, above all, (5) non-conceptual (A284/B340) (9: 99) (Hanna 2001, ch. 4).
