Nin was hopping along one day when he came across a great black raven. The raven was sitting over the corpse of a rabbit, poking and prodding at it with his instruments.

“What are you doing?” asked Nin. He was concerned to see the dead body of a brother desecrated so brazenly.

“Why, I’m learning about rabbits,” replied the raven. “By dissecting this rabbit I am learning how it works. The muscle groups, the organs, the arteries and so forth—rabbit nature, if you will. Come and see.”
