 In any case, the nominal definition of truth must be sharply distinguished from the real definition of truth, i.e., the “criterion” (Kriterium) of truth, which is a rule for determining the truth or falsity of judgments in specific contexts (A58/B82). According to Kant there is no all-purpose or absolutely general criterion of truth (A58–59), such as the “clarity-and-distinctness” criterion of the Cartesians. Nevertheless there are special criteria of truth for each of the basic classes of judgments: analytic judgments, synthetic a posteriori (or empirical) judgments, and synthetic a priori judgments (for more details about this threefold distinction and the special truth-criteria, see  Section 2).
