 A historiographical commonplace of neo-Kantianism has it that the labor of grounding the sciences was divided between the Marburg and Southwest Schools, the former attending to the natural sciences, the latter to the human sciences or Geisteswissenschaften (cf. Oesterreich 1923: 417). Recent scholarship has complicated this picture, reminding us of Rickert’s contributions to philosophy of natural science (cf., e.g., Rickert 1902; 1899), and noting that the Marburg School, too, has a theory of history (esp. Edel 1994; Laks 1994; Lembeck 1994). Already Cohen argues that the disciplinary division between systematic philosophy and the history of philosophy is artificial and harmful; he insists that “the study of philosophy requires the connection of the systematic and historical interest” (Cohen 1902: 440).
