Macbeth - Act 1 Scene 7

The same. A room in Macbeth's castle.

This flurry of activity at the beginning of the scene tells us that it is still evening, and that a dinner is being served in a nearby room, presumably in the same direction from which Macbeth and (later) Lady Macbeth enter.

The language of Macbeth's speech is difficult and vague, but it suggests that he is willing to trade his chance at heaven if he could guarantee success on earth by murdering Duncan.

Macbeth's consideration now becomes more practical: if he becomes king by killing the king, he creates a precedent, leaving himself vulnerable to anyone ambitious enough to try the same thing.

Macbeth describes Duncan as holy and mild, which may be an accurate description of the King, or may be an exaggeration brought on by Macbeth's anxieties.

Macbeth's considerations lead him towards abandoning the murder plot. Just as he recognizes his lack of a "spur" to goad him into action, Lady Macbeth arrives to fulfill that function.

Hautboys and torches. Enter a Sewer, and divers Servants with dishes and
service, and pass over the stage. Then enter MACBETH

MACBETH 
If it were done when 'tis done, then 'twere well
It were done quickly: if the assassination
Could trammel up the consequence, and catch
With his surcease success; that but this blow
Might be the be-all and the end-all, here,
But here, upon this bank and shoal of time,
We'd jump the life to come. But in these cases
We still have judgment here, that we but teach
Bloody instructions, which, being taught, return
To plague the inventor: this even-handed justice
Commends the ingredience of our poisoned chalice
To our own lips. He's here in double trust:
First, as I am his kinsman and his subject,
Strong both against the deed; then, as his host,
Who should against his murderer shut the door,
Not bear the knife myself. Besides, this Duncan
Hath borne his faculties so meek, hath been
So clear in his great office, that his virtues
Will plead like angels, trumpet-tongued, against
The deep damnation of his taking-off;
And pity, like a naked new-born babe,
Striding the blast, or heaven's cherubim, horsed
Upon the sightless couriers of the air,
Shall blow the horrid deed in every eye,
That tears shall drown the wind. I have no spur
To prick the sides of my intent, but only
Vaulting ambition, which o'erleaps itself
And falls on th'other.

Enter LADY MACBETH

How now! What news?

LADY MACBETH 
He has almost supped; why have you left the chamber?

MACBETH 
Hath he asked for me?

  LADY MACBETH 
Know you not he has?

  MACBETH 
We will proceed no further in this business.
He hath honoured me of late; and I have bought
Golden opinions from all sorts of people,
Which would be worn now in their newest gloss,
Not cast aside so soon.

Lady Macbeth's arguments alternate between various tactics, praising Macbeth for his former ambition and chastising him for his current cowardice (which might also be considered as duty or honour).

LADY MACBETH 
Was the hope drunk
Wherein you dressed yourself? Hath it slept since?
And wakes it now, to look so green and pale
At what it did so freely? From this time
Such I account thy love. Art thou afeard
To be the same in thine own act and valour
As thou art in desire? Wouldst thou have that
Which thou esteem'st the ornament of life,
And live a coward in thine own esteem,
Letting 'I dare not' wait upon 'I would,'
Like the poor cat i' the adage?

  MACBETH 
Prithee, peace.
I dare do all that may become a man;
Who dares do more is none.

This comment is a chilling indication of the depths of Lady Macbeth's commitment to the murder plot. It's also a confusing reference, since Lady Macbeth's child is never mentioned again, and Macbeth's childlessness becomes an important plot element later in the play.

LADY MACBETH 
What beast was't, then,
That made you break this enterprise to me?
When you durst do it, then you were a man;
And, to be more than what you were, you would
Be so much more the man. Nor time nor place
Did then adhere, and yet you would make both;
They have made themselves, and that their fitness now
Does unmake you. I have given suck, and know
How tender 'tis to love the babe that milks me;
I would, while it was smiling in my face,
Have plucked my nipple from his boneless gums,
And dashed the brains out, had I so sworn as you
Have done to this.

MACBETH 
If we should fail?

Where Macbeth's consideration of philosophical and religious consequences drove him away from the plan, Lady Macbeth focuses on practical details. Her priorities are accomplishing the murder and not getting caught, and she spares no thought for posterity or the afterlife.

  LADY MACBETH 
  We fail!
But screw your courage to the sticking-place,
And we'll not fail. When Duncan is asleep –
Whereto the rather shall his day's hard journey
Soundly invite him – his two chamberlains
Will I with wine and wassail so convince
That memory, the warder of the brain,
Shall be a fume, and the receipt of reason
A limbeck only: when in swinish sleep
Their drenchèd natures lie as in a death,
What cannot you and I perform upon
The unguarded Duncan? What not put upon
His spongy officers, who shall bear the guilt
Of our great quell?

MACBETH 
Bring forth men-children only;
For thy undaunted mettle should compose
Nothing but males. Will it not be received,
When we have marked with blood those sleepy two
Of his own chamber and used their very daggers,
That they have done't?

LADY MACBETH 
Who dares receive it other,
As we shall make our griefs and clamour roar
Upon his death?

By the end of the scene, Macbeth and Lady Macbeth are once again united in purpose, and Macbeth seems to be taking her advice about becoming a more effective deceiver.

  MACBETH 
I am settled, and bend up
Each corporal agent to this terrible feat.
Away, and mock the time with fairest show:
False face must hide what the false heart doth know.
