 Windelband profoundly disagrees with Dilthey’s strategy for demarcating the historical disciplines. In his Strasbourg rector’s address “Geschichte und Naturwissenschaft” [“History and natural science”] from 1894, he takes issue with the suggestion that the facts of the “sciences of spirit” derive from a particular type of experience. He takes Dilthey to endorse an introspective view of psychological method. To this he objects that the facts of the historical disciplines do not derive from inner experience alone, and that inner perception is a dubious method in the first place. He also classifies psychology with the natural sciences, rejecting Dilthey’s idea that the human-historical disciplines could be founded on a non-explanatory and non-hypothetical descriptive psychology. Perhaps most fundamentally, Windelband rejects the term “sciences of spirit” on the ground that it suggests that the distinction between different sciences rests on a material distinction between different objects: spirit and nature (Windelband 1894: 141–143).
