MacBeth

The title of the book is taken from the despairing speech in William Shakespeare's MacBeth: "Tomorrow, and tomorrow, and tomorrow/ Creeps in this petty pace from day to day,/ To the last syllable of recorded time/ And all our yesterdays have lighted fools/ The way to dusty death. Out, out, brief candle!/ Life's but a walking shadow, a poor player/ That struts and frets his hour upon the stage/ And then is heard no more. It is a tale/ Told by an idiot, full of sound and fury,/ Signifying nothing." At this point in the play, MacBeth has just learned that his wife has killed herself and their plans for seizing the throne will not work out. How are Benjy and Quentin represented in the MacBeth quote? Who do you think is "the idiot"?
