 Intuition is a relation to an “undetermined” (unbestimmt) object or an “appearance” (Erscheinung). Kant uses this phrase to characterize the object of intuition both in the opening of the Transcendental Aesthetic (A20/B34) in the first Critique, and in later discussion in both the Analytic (A69/B94, B154, B163, A141/B180, B309) and the Dialectic (A310/B367, B422n, A443/B471, A718/B746)). Though interpretation of these texts is controversial, the sense in which the object of intuition is “undetermined” seems to specifically involve its lack of conceptual determination, either explicitly in judgment (see, e.g., A69/B94) or via a rule of “figurative” synthesis that guides the imagination (e.g., A141/B180).
