It may be that the brain really only contains maps that are analogues of the physical world. The eyes are a simple mapping of the three dimensional visual world onto two flat maps, the retina at the back of each eye. Binocular vision and a three channel color system provides several maps that are eventually assembled in the brain into maps of line, form, color, motion, and the world in space as it would appear visual if the brain could see directly. Similarly sound is mapped through two ears binaurally in time and by frequency to create a sound map of timbre and spatial location.
It seems possible that, in the brain, the maps of mathematics, morality and meaning are adaptations of the maps of the physical world. What if we move in moral space toward what’s right? In the space of desire toward what is most desired?
