This is what an artist does. She must defamiliarize herself with her everyday perceptions, which depend on—are conditioned by—her past experiences, including the experience of inhabiting a world that is thoroughly conventional. She has to try to perceive as a baby does, or as the empiricist supposes we all do, but this is a subtle and extraordinary accomplishment. There is nothing infantile about good art, but it does show us the world as viewed by a consciousness that has, for a spell, liberated itself from conventionality.
