Freire lays out the process of how the oppressed can truly liberate themselves in chapter 4. He explains the methods used by oppressors to suppress humanity and the actions the oppressed can take in order to liberate humanity. The tools the oppressors use are termed "anti-dialogical actions" and the ways the oppressed can overcome them are "dialogical actions". The four anti-dialogical actions include conquest, manipulation, divide and rule, and cultural invasion. The four dialogical actions, on the other hand, are unity, compassion, organization, and cultural synthesis.
