“It is a mistake, to think the same thing affects both sight and touch. If the same *angle* or square, which is the object of touch, be also the object of vision, what should hinder the blind man, at first sight, from knowing it?”

—George Berkeley (1685–1753)

“Long before I wrote stories, I listened for stories. Listening for them is something more *acute* than listening to them. I suppose it’s an early form of participation in what goes on. Listening children know stories are there. When their elders sit and begin, children are just waiting and hoping for one to come out, like a mouse from its hole.”

—Eudora Welty (b. 1909)
