 The conception of history first sketched in Windelband’s “History and Natural Science” was thoroughly elaborated and expanded in Rickert’s The Limits of Concept Formation in Natural Science. Rickert improves on Windelband’s view in two principal ways: he systematically develops Windelband’s idea that the distinction between history and natural science must be grounded in logic, and he connects the distinction in kinds of sciences to the characteristic SW distinction between fact and value.
