ACT V - Scene III Macbeth

In Act 5, Scene 3, Macbeth is at Dunsinane Castle as enemy forces close in. He defiantly dismisses reports of deserting thanes and clings to the witches' prophecies—that no man born of woman can harm him and that he is safe until Birnam Wood moves to Dunsinane. A terrified servant reports ten thousand English soldiers approaching, and Macbeth berates him furiously. After calling for his armor-bearer Seyton, Macbeth delivers a despairing soliloquy ("I have lived long enough") acknowledging he has lost honor, love, and loyal friends. He then asks the Doctor about Lady Macbeth's condition, learns she suffers from troubled fancies, and demands a cure for a "mind diseased.” When the Doctor says the patient must heal herself, Macbeth dismisses medicine entirely and exits still clinging to the Birnam Wood prophecy.

Macbeth's speech beginning "I have lived long enough" is a moment of devastating self-awareness in which he recognizes the full cost of his tyranny. Using the autumnal metaphor of the "sear, the yellow leaf," he compares his life to a withering plant entering its final season. He lists the blessings that should come with old age—honor, love, obedience, and troops of friends—and acknowledges that none of these await him. Instead, he receives only whispered curses and "mouth-honor," hollow flattery from people too afraid to speak honestly. The speech reveals that despite his hardened exterior, Macbeth retains enough humanity to grieve what his ambition has destroyed.

Macbeth asks the Doctor about Lady Macbeth's condition and is told she is "troubled with thick-coming fancies" that keep her from rest. He then urgently demands a cure, asking whether the Doctor can "minister to a mind diseased, / Pluck from the memory a rooted sorrow, / Raze out the written troubles of the brain." When the Doctor responds that "the patient must minister to himself," Macbeth angrily dismisses all of medicine: "Throw physic to the dogs, I'll none of it." The exchange is dramatically ironic because Macbeth's questions about curing a guilt-ridden mind apply equally to himself.

In Act 5, Scene 3, Macbeth relies on two prophecies delivered by the apparitions conjured by the witches in Act 4. The first prophecy states that "no man that's born of woman / Shall e'er have power" over Macbeth, which he interprets as meaning he is invulnerable to any human adversary. The second prophecy promises that Macbeth will never be defeated until Birnam Wood physically moves to Dunsinane hill, which he considers an impossibility. These prophecies give Macbeth a false sense of security, but both will be fulfilled through unexpected means—Macduff was delivered by caesarean section and is therefore technically not "born of woman," and Malcolm's soldiers camouflage themselves with branches cut from Birnam Wood.

When a young servant enters pale with fear to report the approach of ten thousand English soldiers, Macbeth unleashes a torrent of abuse rather than confront the alarming news. He calls the boy a "cream-faced loon," a "lily-liver'd boy," and a "whey-face," mocking his pallor as a sign of cowardice. This bullying behavior serves a psychological purpose: by attacking the messenger's visible fear, Macbeth avoids acknowledging his own growing terror. The insults also demonstrate how Macbeth's leadership has devolved from inspiring loyalty to ruling through intimidation. His final command—"Take thy face hence"—reveals that the servant's fearful expression is itself unbearable to Macbeth because it mirrors the dread he is trying to suppress.
