George Saunders remembers David Foster Wallace:
"I don't know much about Dave's spiritual life but I see him as a great American Buddhist writer, in the lineage of Whitman and Ginsberg. He was a wake-up artist. That was his work, as I see it, both on the page and off it: he went around waking people up. He was, if this is even a word, a celebrationist, who gave us new respect for the world through his reverence for it, a reverence that manifested as attention, an attention that produced that electrifying, all-chips-in, aware-in-all-directions prose of his."
