What is more acutely disturbing than to see familiar scenes troubled into new life? . . . A true revelation, I am convinced, can only emerge from stubborn concentration on a single problem. I have nothing in common with experimentalists, adventurers, with those who travel in strange regions. The surest, and the quickest, way for us to arouse the sense of wonder is to stare, unafraid, at a single object. Suddenly—miraculously—it will look like something we have never seen before.
