  Rickert enhances and corrects Windelband’s perspective in two ways: (1) He revises his terminology and rejects the phrase ‘idiographic’, which seems to suggest a purely pictorial or reproductive procedure. This would not qualify as knowledge by Rickert’s epistemological standards (see Zijderveld 2006, 246–255; Ferrari 1998). (2) He insists on the necessity of beginning a reflection on the classification of the sciences with a purely methodological criterion, but only to articulate subsequently a more adequate content-related distinction to replace the customary Naturwissenschaft/Geisteswissenschaft pair (Rickert 1962, 11).
