 This “critical and liberating dialogue,” also known as “culture circles,” is the heart of Freire’s pedagogy. The circles consist of somewhere between 12 and 25 students and some teachers, all involved in dialogic exchange. The role of the “teachers” in this civic education is to participate with the people/students in these dialogues. “The correct method for a revolutionary leadership…is, therefore, not ‘libertarian propaganda.’ Nor can the leadership merely ‘implant’ in the oppressed a belief in freedom…The correct method lies in dialogue” (Ibid, 67).
