In Macbeth's Tomorrow speech
To-morrow, and to-morrow, and to-morrow, 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." — Macbeth (Act 5, Scene 5, lines 17-28)
is the last line Signifying nothing litotes?
I have to analyze this segment for school, and I'm a little unclear of what litotes is in practice.
