For Paulo Freire, the Brazilian activist educator and philosopher of education, communication is at the heart of pedagogy, teaching, and learning through praxis that involves reflection and action ultimately to address social injustice and dehumanization. Dialogue is at the center of his pedagogical approach, as means to individuation and humanization. Dialogue assumes participants to be on an equal level even in the presence of difference. In his literacy work, Freire required teacher-facilitators to co-investigate the most important themes in the lives of students. These themes were codified into pictures and brought to dialogue that animated the re-creation of knowledge of participants’ world and themselves in it and, in the process of learning how to read, achieving knowledge of the word. The objective of this approach was not to reproduce “banking” education but to promote revolutionary emancipation of individual and society. Freire developed his work in the context of life in the state of Pernambuco, in the challenging circumstances—socially, historically, and geographically—of the Brazilian Northeast Region. He experienced poverty and hunger and was lucky in his access to education thanks to the efforts of his mother. He rose through the ranks of civil service, serving at state and national levels, addressing the literacy and emancipatory needs of the population, particularly adults in rural areas. Exiled during the military dictatorship in Brazil, Freire lived in Chile, the United States, and Switzerland, where he worked on education projects worldwide.
