Themes in Macbeth

Act I - Scene I 1
"Fair is foul, and foul is fair...."   (Act I - Scene I)

Shakespeare establishes a mysterious, chilling tone and conveys one of the main themes of the play: Things are not what they seem, and the witches suggest that perhaps what is good will be bad, and what is bad will be good.

"O valiant cousin! Worthy gentleman!..."   (Act I - Scene II)

Shakespeare portrays Macbeth in the early scenes of the play at the height of his power and glory. The honors and praise Macbeth receives might seem excessive at times, but Shakespeare uses them for a purpose. Notice how this portrayal of Macbeth shifts throughout the play in order to establish the overall tragedy of Macbeth and the story.

"My thought, whose murder yet is but fantastical,(150) Shakes so my single state of man that function Is smother'd in surmise, and nothing is But what is not...."   (Act I - Scene III)

Macbeth's imagination turns immediately to murderous plots after the witches reveal their prophecy. Macbeth is more frightened by his imagination than his present state because his fantasies begin to take over his reality. "Nothing is but what is not" touches on the major theme in Macbeth of inversion: that which is real becomes unreal when the lines between ambitious fantasy and reality are blurred. In usurping the King, Macbeth converts the real world into his fantasy space and gives life to these murderous thoughts; his thoughts become his state of man.

"insane root..."   (Act I - Scene III)

The herb Banquo refers to is possibly a hemlock or henbane, both of which are deadly. He brings this up to Macbeth as a way to justify the witches sudden disappearance, suggesting that perhaps they have accidentally lost their reason.

"This castle hath a pleasant seat..."   (Act I - Scene VI)

Duncan has never been to or seen Macbeth's castle before. He finds it very pleasant, which is ironic considering the fate that awaits him within. This deception of appearance is a good example of the theme the witches' established early on: Fair is foul and foul is fair. What looks so pretty and pleasant to the King is actually a death trap.

"I see thee still, And on thy blade and dudgeon gouts of blood, Which was not so before...."   (Act II - Scene I)

The illusory dagger becomes covered in blood as Macbeth continues to watch it. This vision adds another supernatural element to the play with symbolic meaning: It represents Macbeth's inner turmoil and feelings of horror about the murder he is about to commit.

"’Tis said they eat each other...."   (Act II - Scene IV)

Shakespeare uses these signs and warnings to foreshadow that more unpleasantness will happen. The eclipse and the story of the owl and falcon to show how nature has become unbalanced as a result of Duncan's murder.

"Hath trifled former knowings...."   (Act II - Scene IV)

In all of his years of experience, the Old Man has never experiences anything as dreadful or strange at the night after Duncan's murder. The use of the word trifle here as a noun means that his previous knowledge or experience seems unimpressive or not noteworthy. This opening statement and the continuing dialogue help to renew the feelings of horror, dread, and unnaturalness surrounding the death of Duncan.

"they say blood will have blood...."   (Act III - Scene IV)

Now that the guests have left, Macbeth relapses and begins to brood over the killing of Banquo. This line indicates that he is certain that the crime will be discoverer and that he will pay for it, that blood will be paid for with more blood. This idea is pervasive throughout the drama as Macbeth's bloody actions lead to bloodier consequences.

"Fillet of a fenny snake, In the cauldron boil and bake; Eye of newt and toe of frog, Wool of bat and tongue of dog,(15) Adder's fork and blind-worm's sting, Lizard's leg and howlet's wing, For a charm of powerful trouble, Like a hell-broth boil and bubble...."   (Act IV - Scene I)

This incantation is the most famous depiction of witchcraft in the Western canon. The three witches's spell emphasizes the play's theme of inversion. They fragment parts of the natural world in order to create an unnatural outcome; in other words, they use pieces of animals instead of whole parts in order to turn reality upside down. The rhyming couplets and lilting seven syllable lines also highlight the enchanting power of language, which can be used to create beauty, or in this case, to engender horrific deception and evil.

"Harpier..."   (Act IV - Scene I)

This word represents a non-standard spelling of "harpy." In Greek and Roman mythology, harpies are horrifying monsters that have women's faces and the bodies of birds. They are regarded as filthy and covetous, always preying on others and wanting more. While they sometimes supposedly administer divine vengeance, commonly their mention or presence contributes to a dangerous or evil atmosphere or theme, as in this case with the witches.

"’tis her command...."   (Act V - Scene I)

Notice how Lady Macbeth's fear of darkness contrasts with her earlier invocation that night cover the bloody deeds surrounding Duncan's murder. Where once she welcomed the darkness for what it offered, now she can't be left alone in it. Considering that light and dark often coincide with good and evil, Lady Macbeth's actions further emphasize her fear and guilt of past sins.

"perturbation..."   (Act V - Scene I)

In this context, "perturbation" refers to a systematic imbalance or disorder with nature, which the Doctor uses to describe Lady Macbeth's natural sleep cycle. However, recall that since the death of Duncan, an imbalance in the natural world has symbolically coincided with Macbeth's reign.

"Out, damned spot!..."   (Act V - Scene I)

This phrase reveals one of the themes in Macbeth: The difficulty of washing away a sin from the soul, of redemption. After killing Duncan, Macbeth was told by his wife to simply wash away the blood (a visual metaphor for his sin). However, this line suggests that subconsciously she knows that cleansing oneself of sin is not possible by any physical means.
