Caliban seems happy to obey. The men begin to quarrel, mostly in jest, in their drunkenness. Stephano has now assumed the title of Lord of the Island and he promises to hang Trinculo if Trinculo should mock his servant monster. Ariel, invisible, enters just as Caliban is telling the men that he is "subject to a tyrant, a sorcerer, that by his cunning hath cheated me of the island" (III.ii.40-41).
Ariel begins to stir up trouble, calling out, "Thou liest" (III.ii.42). Caliban cannot see Ariel and thinks that Trinculo said this. He threatens Trinculo, and Stephano tells Trinculo not to interrupt Caliban anymore.
Trinculo protests that he said nothing. Drunkenly, they continue talking, and Caliban tells them of his desire to get revenge against Prospero. Ariel continues to interrupt now and then with the words, "Thou liest." Ariel's ventriloquizing ultimately results in Stephano hitting Trinculo.
The key, Caliban tells his friends, is to take Prospero's magic books. Once they have done this, they can kill Prospero and take his daughter. Stephano will become king of the island and Miranda will be his queen. Trinculo tells Stephano that he thinks this plan is a good idea, and Stephano apologizes for the previous quarreling. Caliban assures them that Prospero will be asleep within the half hour.
Stephano and Trinculo wonder at this noise, but Caliban tells them it is nothing to fear. Stephano relishes the thought of possessing this island kingdom "where I shall have my music for nothing" (III.ii.139-140). Then the men decide to follow the music and afterward to kill Prospero.
This scene is an example of doubling: almost everything in it echoes Act II, scene i. In this scene, Caliban, Trinculo, and Stephano wander aimlessly about the island, and Stephano muses about the kind of island it would be if he ruled it—"I will kill this man [Prospero]. His daughter and I will be King and Queen . .
. and Trinculo and thyself [Caliban] shall be viceroys" (III.ii.101-103)—just as Gonzalo had done while wandering with Antonio and Sebastian in Act II, scene i.
At the end of Act III, scene ii, Ariel enters, invisible, and causes strife among the group, first with his voice and then with music, leading the men astray in order to thwart Antonio and Sebastian's plot against Alonso. The power-hungry servants Stephano and Trinculo thus become rough parodies of the power-hungry courtiers Antonio and Sebastian. All four men are now essentially equated with Caliban, who is, as Alonso and Antonio once were, simply another usurper.
152-164). After all, Caliban is not only a symbolic "native" in the colonial allegory of the play. He is also an actual native of the island, having been born there after his mother Sycorax fled there. This ennobling monologue—ennobling because there is no servility in it, only a profound understanding of the magic of the island—provides Caliban with a moment of freedom from Prospero and even from his drunkenness.
In his anger and sadness, Caliban seems for a moment to have risen above his wretched role as Stephano's fool. Throughout much of the play, Shakespeare seems to side with powerful figures such as Prospero against weaker figures such as Caliban, allowing us to think, with Prospero and Miranda, that Caliban is merely a monster. But in this scene, he takes the extraordinary step of briefly giving the monster a voice. Because of this short speech, Caliban becomes a more understandable character, and even, for the moment at least, a sympathetic one.
