Throughout his published works, most importantly his two most famous books, The Pedagogy of the Oppressed (1970) and The Politics of Education (1985), he reveals enough of his character through the names he repeatedly invokes: Karl Marx, G.W.F. Hegel, Vladimir Lenin, Mao Zedong, Fidel Castro, and, in pride of place, Che Guevara. Few, if any, theorists of education (pedagogues) are ever named, referenced, or put into application.
