Is that a reference to the fact that the image of the world is reversed as it passes through your cornea and strikes the retina, and must be flipped over by the brain?
Or do we just think that the brain flips the image because we can't handle the thought that the world really is upside down?
Interestingly thinking about this has me wonder how much "flipping" the brain is actually capable of, since "up" and "down" are mere concepts and the brain is not capable of completing a physical task such as "flipping," if that makes any sense. I don't think it would matter which way we interpreted up and down, because our entire brain would function accordingly, so long as it was a consistant reference frame. I don't think the brain flips the image at all, but merely the idea of "up" and "down" have no physical retraint in the concept our brain has of the environment around us.
i.e. there is no "up" and "down" except the "up" and "down" that the brain gives us. Imagine looking at a painting and then flipping it whichever way you chose. If there is a person inside that picture, "up" points in the same direction inside that picture no matter which direction it points in relation to outside the picture.
I like to make things up.
