Humans and beasts are different species, but foxes are between humans and beasts. The dead and the living walk different roads, but foxes are between the dead and the living. Transcendents and monsters travel different paths, but foxes are between transcendents and monsters. Therefore one could say to meet a fox is strange; one could also say it is ordinary.
Human beings and physical objects belong to two different categories; fox-spirits stand somewhere between the two. The paths of light and darkness never converge: fox-spirits stand somewhere between the two. Immortals and demons go different ways; fox-spirits stand somewhere between the two.
~ Ji Yun, 1789, in Notebook from the Thatched Cottage of Close Scrutiny
