“We’re all inadequate,” David answered. “Just think: the light from the outside world is mapped onto the retina, then further mapped onto the visual cortex, then broken apart and analyzed in other areas of the brain. At every step there’s a loss of information. In the end, what we are aware of is not the outside world per se, but the image of the world projected onto our brains. Plato was anatomically right; we do see shadows on a wall.”
