This essay analyzes one story toward the end of The Thousand Nights and a Night. The story tells us about a fisherman Abdullah who met a merman or man from the sea. My analysis finds in this story two striking accounts, first of causation in nature and, second, of the connection of economic value to human labor. As for the first, I think the story's account of causation in nature was close to philosophical occasionalism. Seen from a 21st century perspective, this story also had a little bit of economics. Value was only contiguous with human labor, the story said, or in other words labor was only next in sequence to value, not the cause of value.
