The boy has said the emperor is naked, has he? Of course, to the scientifically untrained eye, the emperor no doubt looks naked. But those of us who know a few things about the science of vision know better. The perceptual skills of someone his age are clearly not sufficiently developed to allow him to assert this with any certainty. Those of us who have studied perception know how unreliable eyewitness testimony is. We know how often our eyes deceive us when we want to see something that isn’t there. This young man has not studied the science of perception and illusion, if he did, he would certainly not assert so vociferously that his perception of the emperor’s nudity was veridical.
