What is the theme in Theatre of the Oppressed by Augusto Boal?

Another theme is theater as politics.Boal describes Aristotle's categorization of arts and sciences into major and minor arts and sciences. Minor arts might be making a brick or a paintbrush. These, in turn, are part of a larger art, such as architecture or painting. These in turn are part of even more major arts, such as town planning or visual arts. Boal represents politics as the highest art, encompassing all interaction between humans. Therefore, politics are comprised of all the lesser activities of man. Within the scope of this definition, which Boal seems to subscribe to, as well as ascribing it to Aristotle, everything is political, including (and especially in the context of the book) theater.
