One way of seeing, in Wittgenstein’s formulation, is what we might call accurate seeing. This is how the blind man sees after Jesus touches his eyes for a second time, and he sees “every man clearly.” The other way of seeing is more like seeing men as trees walking. Wittgenstein calls this metaphorical way of seeing “seeing as.” He tells us, for example, that he “may well try to see” the letter F “as a gallows.” “Could there be human beings lacking in the capacity to see something as something?” Wittgenstein wonders. He suggests that this condition might be called “aspect-blindness” and compares it to “the lack of a ‘musical ear.’”
