Human societies like dividing things into two categories. They’ve been doing it for a long time. For instance, a large chunk of Leviticus in the Old Testament is about dividing things into the categories of clean and unclean. The Codes of Hammurabi involve dividing things into the legal and the illegal. There are plenty more examples where those came from. This article is about ways of visualising how people divide up their world when they go beyond the simple two-category approach.
