But there is another noticeable point about this speech, "He has no children," which is, that elsewhere we are led to believe that he has children. Lady Macbeth says, "I have given suck, and know how tender 'tis to love the babe that milks me;" and we have neither learned that these children are dead nor that they were born of an earlier marriage. Shakespeare never mentions the former marriage of the historical Lady Macbeth. Furthermore, not only does she talk of children, but Macbeth himself seems to allude to sons. He says (iii. I):—
"Upon my head they plac'd a fruitless crown,
And put a barren sceptre in my gripe,
Thence to be wrench'd with an unlineal hand,
No son of mine succeeding. If't be so,
For Banquo's issue have I filed my mind."
If he had no children of his own, the last line is meaningless. Had Shakespeare forgotten these earlier speeches when he wrote that ejaculation of Macduff's? It is improbable; and, in any case, they must have been constantly brought to his mind again at rehearsals and performances of the play. We have here one of the difficulties which would be solved if we were in possession of a complete and authentic text.
The crown which the Witches promised to Macbeth soon becomes his fixed idea. He murders his king—and sleep. He slays, and sees the slain for ever before him. All that stand between him and his ambition are cut down, and afterwards raise their bloody heads as bodeful visions on his path. He turns Scotland into one great charnel-house. His mind is "full of scorpions;" he is sick with the smell of all the blood he has shed. At last life and death become indifferent to him. When, on the day of battle, the tidings of his wife's death are brought to him, he speaks those profound words in which Shakespeare has embodied a whole melancholy life-philosophy:—
"She should have died hereafter:
There would have been a time for such a word.—
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."
This is the final result arrived at by Macbeth, the man who staked all to win power and glory. Without any underlining on the part of the poet, a speech like this embodies an absolute moral lesson. We feel its value all the more strongly, as Shakespeare's study of humanity in other parts of this play does not seem to have been totally unbiassed, but rather influenced by the moral impression which he desired to produce on the audience. The drama is even a little marred by the constant insistence on the fabula docet, the recurrent insinuation that "such is the consequence of grasping at power by the aid of crime." Macbeth, not by nature a bad man, might in the drama, as in real life, have tried to reconcile the people to that crime, which, after all, he had reluctantly committed, by making use of his power to rule well. The moral purport of the play excludes this possibility. The ice-cold, stony Lady Macbeth might be conceived as taking the consequences of her counsel and action as calmly as the high-born Locustas of the Renaissance, Catherine de' Medici, or the Countess of Somerset. But in this case we should have missed the moral lesson conveyed by her ruin, and, what would have been worse, the incomparable sleep-walking scene, which—whether it be perfectly motived or not—shows us in the most admirable manner how the sting of an evil conscience, even though it may be blunted by day, is sharpened again at night, and robs the guilty one of sleep and health.
In dealing with the plays immediately preceding Macbeth, we observed that Shakespeare at this period frequently gives a formal exposition of the moral to be drawn from his scenes. Possibly there is some connection between this tendency of his and the steadily-growing animosity of public opinion to the stage. In the year 1606, an edict was issued absolutely prohibiting the utterance of the name of God on the profane boards of the theatre. Not even a harmless oath was to be permitted. In view of the state of feeling which produced such an Act of Parliament, it must have been of vital importance to the tragic poet to prove as clearly as possible the strictly moral character of his works.
