Macbeth Passage help: who is the fool and the idiot?

Question

From the following speech in Macbeth:

Act 5 Scene 5 Lines 20-31

MACBETH

She should have died hereafter. 20
There would have been a time for such a word.
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 25
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, 30
Signifying nothing.




Who do you think/ know the fool and the idiot is?
And what is sound and fury referring to?

Answer 1

We are, all of us, the fools (though in this passage, Macbeth is speaking only about all those who lived and died before him.)
We are fools because we believe that life has meaning and that there is something beyond the grave.
The idiot - the one who tells the tale of life - is chaos,
the uncreated, eternal universe. Or it could be a "Creator", certainly not the one found in religion, but one that has no concern whatsoever concern for the creation. Life is full of the meaningless noise we make and the meaningless actions we perform, both of which have no significance and have no purpose.

Answer 2

All human beings are fools and all of our past has shown the way to dusty (dust to dust, ashes to ashes) death. Any tale about human life sounds like it's told by an idiot. Of course, what does that make Shakespeare?

Answer 3

No one specifically. It refers to life being how a story told by an idiot might sound, full of noise and passion, but without meaning.

Answer 4

it is not anyone specifically, it just means that Macbeth's life mean's nothing- it's an idiot's tale.
The sound and fury are all the bad/evil things in Macbeth's life- the murders etc.
