The other day, I was doing some document conversion for the Haida Language Program (the Haidas are a SE-Alaskan group), and in with the megs and megs of language datae, I found this:
«The world is like a knife blade.
When you are walking watch your step.
You will "fall off the edge of the earth".
On hearing this Haida philosophy of world view, a young lad ridiculed it by prancing around and saying, "Hey, look I'm falling off of the world." While prancing around he stepped on a fish bone and developed fish poisoning and died. Thus the old people say he had fallen off of the world.»
Not the coziest world-view. But then, if I owned slaves, I too would have gotten into the habit of constantly looking over my shoulder.
