 Still, the common view, if one-sided, is not wrong, for the Marburg theory of history has a very different starting-point than does the Southwest School. Unlike Rickert and Windelband, Cohen and Natorp do not begin their theory of history from the “fact” of historical science, in the way they begin their theory of natural science from the “fact” of mathematical physics. When they speak of history, they mean, on the one hand, the history of science, and on the other, the history of philosophy, properly construed, namely as the critique of science. Only secondarily are they interested in political, economic, or social history, and only insofar as it advances their primary  project.[33]
