I argue that the sensibility/understanding distinction announced at the end of Kant’s Introduction to the Critique can be justified via pure apperception. I first defend an account of the analytic/synthetic distinction, arguing that analytic judgments articulate intellectual grounds of truth. Synthetic judgments, then, are based on nonintellectual grounds of truth. This provides Kant’s “baseline conception” of receptive intuition as a capacity for representing nonintellectual grounds of truth. This is a “top-down” approach to intuition: a characterization of intuition not in terms of its intrinsic properties but in terms of a prior account of the intellect and its cognitive needs. I then argue that this version of the analytic/synthetic distinction follows from the idea that judgment must track the truth – an idea that is available to us via pure apperception. Thus, Kant’s baseline conception of intuition, as expressed in the sensibility/understanding distinction, can be justified via pure apperception.
