When a real object causes an image of itself to form on each of the retinas of our eyes, the image is upside down. It used to be thought that there was a 180 degree twist in the optic nerve to turn it right side up again, but then it was found that there is no such twist. So now it is believed that the image is reoriented in the unconscious mind. Does it not follow that when we see something, we see a twice inverted image of the real object, not the real object itself?
