“Rabbit’s clever,” said Pooh thoughtfully.
“Yes,” said Piglet, “Rabbit’s clever.”
“And he has Brain.”
“Yes,” said Piglet, “Rabbit has Brain.”
There was a long silence.
“I suppose,” said Pooh, “that that’s why he never understands anything.”

When an organ is conceptualized as an external tool for internal processing and understanding, we forget that the organ itself, its process, and its product, are equally part of the person. I don’t have a body, I am body. Rabbit doesn’t have brain, but Rabbit isn’t just brain either. Rabbit is all the things that make up Rabbit including the brain, but, as Pooh points out, once we conceptualize the self as only one part, we cease to understand the whole.
