what are the themes given to character of ariel

Perhaps the most important theme in the play is slavery, specifically, the effects of slavery on indigenous populations in colonized areas. Prospero takes on the role of the colonial ruler, ousting Caliban, the former leader, and instituting slavery. Caliban and Ariel represent those who are subject to this colonization, but take different tacks. Ariel believes that he will be liberated if he makes nice with his master and tries to win favor, while Caliban thinks contentious resistance is the only way to liberation.
