 Kant does not endorse a Humean solution to the problem of the relation between cause and effect in the critical period (beginning with the first edition of the Critique in 1781): he does not (as he had in Dreams of a Spirit-Seer) claim that this relation is derived from experience. Instead (as we have seen) Kant takes Hume’s problem of causality to be centrally implicated in the radically new problem of synthetic a priori judgments. Yet the latter problem, in turn, clearly has its origin in Kant’s earlier discussion (in the essay on Negative Magnitudes and Dreams of a Spirit-Seer) of the apparently mysterious connection between a real ground (or cause) and its consequent (or effect).

Such a judgment, in Kant’s critical terminology, must now be synthetic—it is a judgment in which “the connection of the predicate with the subject … is thought without identity”, where
