Tree of Smoke is the title of a kick-ass-wonderful new novel by Denis Johnson. Set in a CIA Psy Ops Group in Vietnam in 1967, it offers this nugget of neurophilosophy:
"Something's warping you," Jimmy told the lieutenant. "Maybe it's your perception of how the brass will see you-- but they're not seeing you at all right now, so it's a perception of a nonperception, man, which is a perception of nothing, which is nothing, man."
