Four fingers. (trankerlicer)

After the Agricultural Revolution, human societies grew ever larger and more complex, while the imagined constructs sustaining the social order also became more elaborate. Myths and fictions accustomed people, nearly from the moment of birth, to think in certain ways, to behave in accordance with certain standards, to want certain things, and to observe certain rules. They thereby created artificial instinct that enabled millions of strangers to cooperate effectively. This network of artificial instincts is called 'culture'.
