The Aesthetics of the OppressedIn The Aesthetics of the Oppressed (2006), his sixth book, Augusto Boal provides us with the set of principles underlying his Theatre of the Oppressed. Boal’s deft fingers explore a vast array of subjects, plucking ideas like candies from a bowl and then letting us suck on the sugared morsels until we understand his background, beliefs, and the points he tries to get across.
