 The characteristically rational activity of taking-for-true implies the subjective validity of a judgment, or its apparent meaningfulness and apparent truth for an individual rational cognizer. By contrast, the “objective validity” (objektiv Gültigkeit) of a judgment is its empirical meaningfulness, precisely because it is compositionally based on the empirical “reference” (Beziehung)—whether singular or comprehensional—of the basic constituent objective representations of any judgment, namely intuitions and concepts. The empirical reference of intuitions and concepts, in turn, is necessarily constrained by the specifically aesthetic or sensible, non-conceptual, non-discursive, and pre-rational or proto-rational dimension of human experience, which itself is jointly determined by (a) the brute givenness of material objects to our receptive capacity for empirical intuition, via the relation of external affection, and (b) the necessary and non-empirical forms of empirical intuition, our representations of space and time (A19–22/B33–36), which ultimately express the outer and inner sensory aspects of the embodiment of our minds). In this way, an intuition is objectively valid if and only if either (i) it directly refers to some individual actual or possible external sensible object or to the subject’s phenomenally conscious inner response to this outer reference (this accounts for the objective validity of empirical intuitions), or else (ii) it represents a phenomenally immanent necessary condition of empirical intuitions (this accounts for the objective validity of the forms of intuition) (A239–240/B298–299). By contrast, a concept is objectively valid if and only if either it applies to some actual or possible objects of empirical intuition (this accounts for the objective validity of empirical concepts) or else it represents a necessary condition of empirical concepts (this accounts for the objective validity of pure concepts) (A239–240/B298–299, A240–242/B299–300).
