You taught me language, and my profit on’t
Is I know how to curse. The red plague rid you
For learning me your language! (I.ii.366–368)

This speech, delivered by Caliban to Prospero and Miranda, makes clear in a very concise form the vexed relationship between the colonized and the colonizer that lies at the heart of this play. The son of a witch, perhaps half-man and half-monster, his name a near-anagram of “cannibal,” Caliban is an archetypal “savage” figure in a play that is much concerned with colonization and the controlling of wild environments. Caliban and Prospero have different narratives to explain their current relationship. Caliban sees Prospero as purely oppressive while Prospero claims that he has cared for and educated Caliban, or did until Caliban tried to rape Miranda. Prospero’s narrative is one in which Caliban remains ungrateful for the help and civilization he has received from the Milanese Duke. Language, for Prospero and Miranda, is a means to knowing oneself, and Caliban has in their view shown nothing but scorn for this precious gift. Self-knowledge for Caliban, however, is not empowering. It is only a constant reminder of how he is different from Miranda and Prospero and how they have changed him from what he was. Caliban’s only hope for an identity separate from those who have invaded his home is to use what they have given him against them.
