Macbeth’s imagination is, however, a ruling characteristic of his nature. His brain is always active; and when it does not evoke phantoms, it indulges in fanciful and poetic images. He is a poet, and turns everything into poetry. His utterance is generally excited and high-flown, rarely simple and real, and almost never expresses his true feelings and thoughts. His heart remains cold while his head is on fire. On all occasions his first impulse is to poetize a little; and having done this, he goes about his work without regard to what he has said. His sayings are one thing; his doings are quite another. Shakespeare makes him rant intentionally, as if to show that in such a character the imagination can and does work entirely independently of real feelings and passions. There is no serious character in all Shakespeare’s plays who constantly rants and swells in his speech like Macbeth; and this is plainly to show the complete unreality of all his imaginative bursts. In this he differs from every other person in this play. Yet when he is really in earnest, and has some plain business in hand, he can be direct enough in his speech, as throughout the second interview with the weird sisters, and in the scene with the two murderers whom he sends to kill Banquo and Fleance; or when, enraged at the escape of Fleance, he forgets to be a hypocrite, and his real nature clearly expresses itself in direct words, full of savage resolve. But on all other occasions, when he is not in earnest and intends to deceive, or when his brain is excited, he indulges in sentimental speeches, violent figures of speech, extravagant personifications, and artificial tropes and conceits. Even in the phantom-voices he imagines crying to him over Duncan’s body, he cannot help this peculiarity. He curiously hunts out conceits to express sleep. He “murders sleep, the innocent sleep; sleep, that knits up the ravell’d sleeve of care, the death of each day’s life, sore labor’s bath, balm of hurt minds, great nature’s second course, chief nourisher in life’s feast.” No wonder that Lady Macbeth, amazed, cries out, “What do you mean?” But he cannot help going on like a mad poet. His language is full of alliteration, fanciful juxtaposition of words, assonance, and jingle. At times, so strong is this habit, he makes poems to himself, and for the moment half believes in them. Only compare, in this connection, the natural, simple pathos of the scene where Macduff hears of the barbarous murder of his wife and children, with the language of Macbeth, when the death of Lady Macbeth is announced to him. Macduff “pulls his hat upon his brows,” and gives vent to his agony in the simplest and most direct words. Here the feeling is deep and sincere:— “All my pretty ones? Did you say, all?—O hell-kite!—All? What, all my pretty chickens, and their dam, At one fell swoop? _Mal._ Dispute it like a man.
