In Ways of Seeing, John Berger identifies seeing as the first human sense. “Seeing comes before words,” he writes. “The child looks and recognizes before it can speak.” This is true. But it is also true that images affect people in ways very different from words. They are more precise, but not as discursive. In some ways, in fact, they may be less precise. Images, Berger also writes, were first used to conjure an image of something that was absent.
