Question

Why are these lines from Act III important in the plot of the play? (25 points)
Macbeth to Lady Macbeth

the time has been,
That, when the brains were out, the man would die,
And there an end; but now they rise again,
With twenty mortal murders on their crowns,
And push us from our stools: this is more strange
Than such a murder is

Answer 2

I had to go get my copy of the book, this is from Act 3, Scene 4, correct?

Answer 3

it doesn't say what scene just act 3.

Answer 4

Alright, don't worry about it, I can work with that. Give me a moment to read this again.

Answer 5

The first thing I would do here is to simply translate this from Shakespearean to Modern English, which is relatively easy;
It used to be that when you knocked a man’s brains out he would just die, and that would be it. But now they rise from the dead with twenty fatal head wounds and push us off our stools. This haunting business is even stranger than murder.
Now that you know exactly what is being said, you have to think about how these words apply to the play itself. Macbeth is saying this to Lady Macbeth, trying to convince her that he had seen the ghost, and she just scolds him, telling him to go back to his guests.
From knowing all this, these lines are most likely here to emphasize on murder, and what happened to people, as well as being said after the ghost disappears, and then reappears shortly after these lines. It is meant to leaves an uneasy feeling to wonder what will happen next.
