The problems of what evidence does, which confront us as logicians, are — since all judgments point back to experience — problems concerning experience/itself and problems concerning the categorialia deriving from experience. The two sets of problems are interwoven in the task of clearing up the lowest level of judging [Urteilsstufe], correlatively the lowest level of categorialia, those that still bear their experiential source immediately within them. The way to these problems leads us (since we are letting ourselves be guided toward a transcendental logic by a criticism of naive logic and its positivity) first of all to a criticism of the naïve concepts of evidence and truth, or true being, that govern the whole logical tradition.
