 Windelband uses the terms “axioms” and “values” interchangeably to refer to the most fundamental rules, and he uses the term “norms” often, but not fully consistently to refer to values or axioms as they relate to psychological experience and the cultural-historical world. Focusing his interpretation on “values” and “norms”, Windelband captures the structural similarity of Kant’s three Critiques in terms of immanent truth: if truth is nothing other than accordance with a rule, then there is moral and aesthetic truth in just the same way as there is epistemic truth (1881: 140). In a later text, Windelband describes the unified project of the three Critiques in terms of the necessary and universal relation between thought and object. He writes that the postulates of practical reason relate to intelligible objects (ideas) just “as necessarily” as the intuitions and categories relate to the object of experience, and that teleological judgment constructs the purposive whole of nature just “as universally” as the principles of pure understanding apply the categories to experience (1904a: 151). While this formulation glosses over some of the nuances of the distinction between constitutive and regulative uses of reason, Windelband’s main intention is not that of giving a detailed and fully accurate reconstruction of Kant’s philosophy. In line with his famous dictum that “understanding Kant means to go beyond him” (1915: iv), he instead seeks to revive the critical project in a manner that allows it to answer the needs of his own time. And Windelband thinks that the critical philosophy required at the time of his writing is a “philosophy of values” which reveals the most fundamental values in epistemology, ethics, and aesthetics.
