Discovery leads to new worlds and possibilities :

Imaginative discovery

Boatswain's speculation amidst the new world of the chaotic storm was the contingency that the Elizabethan power structure may be subverted and thrown into chaos, and those from lower positions within the Great Chain of Being may therefore ascend to attain a higher status.

'What cares these roarers for the name of the king?'

Rhetorical question shows the contempt that the Boatwswain has developed for the lives of his superiors.

Completely defying the conventions of the time which stipulated that he must obey those of a higher rank who were appointed by the Heavens, even to the point of death.

Within the new, magical world generated by Prospero's sorcery, Caliban undergoes many imaginative realisations that a transcendent, glorious plane of existance is possible, which ultimately proves false when he awakes from his dreaming.

'You do mar our labour!'

'None that I love more than myself'

Reprimand

'Sometimes a thousand twangling instruments / Will hum about mine ears, and sometime voices / That, if I then had waked after long sleep, / Will make me sleep again.'

'Be not afeard. The isle is full of noises, / Sounds, and sweet airs that give delight and hurt not.'

The low modality of the term 'sometimes' indicates how the periods of hallucination-like euphoria that Caliban experiences under the influence of Prospero are considered as precious as they are infrequent, utterly dependant upon the caprice of the sorcerer.

Moreover, the mellifluousness is accentuated by the onomatopoeia in the terms 'twangling' and 'hum', reinforced by the assonance of tie 'in' vowels of 'instruments, emphasising how the ex-Duke's art can conjure up a state of pure bliss at will.

This magical illusion functions in a way that decieves Prospero's subjects such as Caliban into thinking themselves in a new, paradisiacal landscape, and consequently into making them forget the restrictions of their reality, and instead suppose that pleasure and liberty are prospects available to them. However, Caliban ultimately realises the sobering truth of his powerlessness before Prospero when the sorcerer re-enters his world, removing any possibility of autonomy or utopia.

The unprecedented universe of the isle affords Gonzalo a chance to reenvinsion the potential of creating a new utopia where social inequality was eliminated and replaced with a laissez-faire economy.

The contextual notion of Terra Nullius, as the Latinate legal definition went, typified the mentality most Europeans had when approaching a new environment, presuming that they could appropriate the land without any repercussions from the indigenous.

'Bourn, bound of land, tilth, vineyard, none; / No use of metal, corn, or wine, or oil; / No occupation; all men idle, all, / And women too, but innocent and pure;'

'No sovereignty— ... / All things in common nature should produce / Without sweat or endeavor: treason, felony, / Sword, pike, knife, gun, or need of any engine, / Would I not have;'

'...but nature should bring forth / Of its own kind, all foison, all abundance, / To feed my innocent people.'

Stephano and Trinculo arrive on the blank and uninhabited world of the magical isle, full of the potential for self-aggrandisement, licentiousness, rebelliousness, indulgence and revelry, enabling them to fantasise about the opportunity to rise to the top of the social hierarchy

'Trinculo, keep a good tongue in your head. If you prove a mutineer, the next tree. The poor monster’s my subject and he shall not suffer indignity.

'Marry, will I. Kneel and repeat it. I will stand, and so shall Trinculo'

'Monster, I will kill this man. His daughter and I will be king and queen—save our graces!—and Trinculo and thyself shall be viceroys.—Dost thou like the plot, Trinculo?'

This collapse of false possibilities which coincides with the collapse of Caliban's illusion that the island can be made into a new world brings about a profound shift in his personality, evoking deep repentance and a new self awareness.

'What a thrice-double ass I was!'
