To postmodernists et al: Korzybskis oft-quoted "the map is not the territory" presupposes there is a territory. And he went on to say that "a maps usefulness lies in its structural similarity to reality." Maps are not arbitrary; they should be rational. We understand the universe through mental models - maps - but some maps are plain wrong, while others are the best we can make so far.
