Neither objective or subjective, urphaenomene [the term is Goethe's, from his Metamorphosis of Plants] "come into existence as types, or as laws, only as they are intuited by human beings. And until they have so come into being, the object itself is incomplete. Knowledge in fact, so far from being a mental copy of events and processes inside the human being, inserts the human being right into these processes, of whose development it is itself the last stage" (RCA 37).
