What are the motifs in Theatre of the Oppressed by Augusto Boal?

In Boal's view, the difference between the spectator and the actor is artificial. Every person has the capacity for art, as a human being, and by taking the active role away from the spectator, the theater is dehumanizing and oppressing the spectator. The spectator's identity, thoughts, and feelings are co-opted by the theater. The spectator-actor relationship is a dichotomy. They are opposites, and in traditional theater, they are forces that are actively antagonistic. The actor usurps the spectator's identity and humanity.
