When Annie Dillard was writing her 1974 naturalist classic, “Pilgrim at Tinker Creek,” she says that she didn’t think anyone would read it beyond a few monks. After the book won the Pulitzer Prize for General Nonfiction, it wound up reaching a much larger audience. Now, after a lifetime of writing and more than a decade in retirement, Dillard tells David Remnick which of her books she thinks gets closest to “a vision of where we are on this earth.”
