 “Kant posed a new conception of philosophy’s task and mode of knowledge against the psychologism of his contemporaries”, Windelband writes in his programmatic essay, “Critical or Genetic Method?” (Windelband 1883: 271). On this Kantian view, Windelband asserts, philosophy’s subject matter is the “validity” [Geltung] of “axioms”. Philosophy must identify these axioms, put them into a system, and explain how these axioms govern the activities of knowing, acting, and judging. This latter task requires giving a general account of validity, in addition to identifying how the various sciences and areas of culture are governed by specific axioms. Logic (or theoretical philosophy, or “theory of knowledge”) is the science of the axioms for knowing; ethics is the science of the norms for acting; aesthetics is the science of the rules of the “effects of the emotions” (1883: 274–5).
