A good many readers probably think that, when Macbeth first met the Witches, he was perfectly innocent; but a much larger number would say that he had already harboured a vaguely guilty ambition, though he had not faced the idea of murder. And I think there can be no doubt that this is the obvious and natural interpretation of the scene. Only it is almost necessary to go rather further, and to suppose that his guilty ambition, whatever its precise form, was known to his wife and shared by her. Otherwise, surely, she would not, on reading his letter, so instantaneously assume that the King must be murdered in their castle; nor would Macbeth, as soon as he meets her, be aware (as he evidently is) that this thought is in her mind.
But there is a famous passage in Macbeth which, closely considered, seems to require us to go further still, and to suppose that, at some time before the action of the play begins, the husband and wife had explicitly discussed the idea of murdering Duncan at some favourable opportunity, and had agreed to execute this idea. Attention seems to have been first drawn to this passage by Koester in vol. I. of the Jahrbücher d. deutschen Shakespeare-gesellschaft, and on it is based the interpretation of the play in Werder's very able Vorlesungen über Macbeth.
The passage occurs in I. vii., where Lady Macbeth is urging her husband to the deed:
Macb. Prithee, peace:
I dare do all that may become a man;
Who dares do more is none.Lady M. 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 pluck'd my nipple from his boneless gums,
And dash'd the brains out, had I so sworn as you
Have done to this.
Here Lady Macbeth asserts (1) that Macbeth proposed the murder to her:
Now it is possible that Macbeth's 'swearing' might have occurred in an interview off the stage between scenes v. and vi., or scenes vi. and vii.; and, if in that interview Lady Macbeth had with difficulty worked her husband up to a resolution, her irritation at his relapse, in sc. vii., would be very natural. But, as for Macbeth's first proposal of murder, it certainly does not occur in our play, nor could it possibly occur in any interview off the stage; for when Macbeth and his wife first meet, 'time' and 'place' do adhere; 'they have made themselves.' The conclusion would seem to be, either that the proposal of the murder, and probably the oath, occurred in a scene at the very beginning of the play, which scene has been lost or cut out; or else that Macbeth proposed, and swore to execute, the murder at some time prior to the action of the play.[291] The first of these hypotheses is most improbable, and we seem driven to adopt the second, unless we consent to burden Shakespeare with a careless mistake in a very critical passage.
And, apart from unwillingness to do this, we can find a good deal to say in favour of the idea of a plan formed at a past time. It would explain Macbeth's start of fear at the prophecy of the kingdom. It would explain why Lady Macbeth, on receiving his letter, immediately resolves on action; and why, on their meeting, each knows that murder is in the mind of the other. And it is in harmony with her remarks on his probable shrinking from the act, to which, ex hypothesi, she had already thought it necessary to make him pledge himself by an oath.
Yet I find it very difficult to believe in this interpretation. It is not merely that the interest of Macbeth's struggle with himself and with his wife would be seriously diminished if we felt he had been through all this before. I think this would be so; but there are two more important objections. In the first place the violent agitation described in the words,
If good, why do I yield to that suggestion Whose horrid image doth unfix my hair And make my seated heart knock at my ribs,
would surely not be natural, even in Macbeth, if the idea of murder were already quite familiar to him through conversation with his wife, and if he had already done more than 'yield' to it. It is not as if the Witches had told him that Duncan was coming to his house. In that case the perception that the moment had come to execute a merely general design might well appal him. But all that he hears is that he will one day be King--a statement which, supposing this general design, would not point to any immediate action.[292] And, in the second place, it is hard to believe that, if Shakespeare really had imagined the murder planned and sworn to before the action of the play, he would have written the first six scenes in such a manner that practically all readers imagine quite another state of affairs, and continue to imagine it even after they have read in scene vii. the passage which is troubling us. Is it likely, to put it otherwise, that his idea was one which nobody seems to have divined till late in the nineteenth century? And for what possible reason could he refrain from making this idea clear to his audience, as he might so easily have done in the third scene?[293] It seems very much more likely that he himself imagined the matter as nearly all his readers do.
But, in that case, what are we to say of this passage? I will answer first by explaining the way in which I understood it before I was aware that it had caused so much difficulty. I supposed that an interview had taken place after scene v., a scene which shows Macbeth shrinking, and in which his last words were 'we will speak further.' In this interview, I supposed, his wife had so wrought upon him that he had at last yielded and pledged himself by oath to do the murder. As for her statement that he had 'broken the enterprise' to her, I took it to refer to his letter to her,--a letter written when time and place did not adhere, for he did not yet know that Duncan was coming to visit him. In the letter he does not, of course, openly 'break the enterprise' to her, and it is not likely that he would do such a thing in a letter; but if they had had ambitious conversations, in which each felt that some half-formed guilty idea was floating in the mind of the other, she might naturally take the words of the letter as indicating much more than they said; and then in her passionate contempt at his hesitation, and her passionate eagerness to overcome it, she might easily accuse him, doubtless with exaggeration, and probably with conscious exaggeration, of having actually proposed the murder. And Macbeth, knowing that when he wrote the letter he really had been thinking of murder, and indifferent to anything except the question whether murder should be done, would easily let her statement pass unchallenged.
This interpretation still seems to me not unnatural. The alternative (unless we adopt the idea of an agreement prior to the action of the play) is to suppose that Lady Macbeth refers throughout the passage to some interview subsequent to her husband's return, and that, in making her do so, Shakespeare simply forgot her speeches on welcoming Macbeth home, and also forgot that at any such interview 'time' and 'place' did 'adhere.' It is easy to understand such forgetfulness in a spectator and even in a reader; but it is less easy to imagine it in a poet whose conception of the two characters throughout these scenes was evidently so burningly vivid.
