The Tempest 5

THE TEMPEST In The Tempest, it would seem that no two characters could be further apart than Prospero, the "right duke of Milan", and Caliban, the "salvage and deformed slave." They represent two different extremes on the social spectrum: that of the natural ruler, and the naturally ruled. Their positions on the social hierarchy are largely due to the fact that Caliban responds almost wholly to passions, feelings of pleasure -- his senses, while Prospero …

…but training him to become part of that society cannot be abstract, like Prospero's failed attempt at educating him with Miranda -- Caliban's education must be practical and hammered home with his own senses. Neither Prospero nor Caliban cannot be said to be wholly mind or sensual passion, but Caliban does rely largely on his senses, and by the end of the play, Prospero's mind has achieved a great extent of control over his passions.
