Hamlet's words come to mind:"...A sound made by an idiot, full of sound and fury, signifying nothing."

Oops! This one's not Hamlet, but Macbeth, who, in his great "Tomorrow and tomorrow" speech, calls life "a tale told by an idiot, full of sound and fury, signifying nothing." It's The Bard, so we gotta keep it straight.This whole soliloquy is IMHO a most powerful expression of nihilism.
