In this classic presented in a new edition, Paulo Freire argues that the task of teaching cannot be reduced to the transmission of content or skills but, on the contrary, must advance to engage teachers and students with their social and cultural environment. For the author of Pedagogy of the Oppressed, the ethical dimension cannot be absent from any link and even less from the one established between those who teach and those who learn, since this dimension is what allows us to integrate and respect the other, understand our own and others' changes and recognize injustice. But above all, the reason for the inclusion of the ethical dimension in teaching is given because the author sees in ethics, the way to build a sense of autonomy and personal responsibility. "Why not discuss with the students about the concrete reality, to which the subject whose content is taught must be associated; the aggressive reality in which violence is the constant, and the coexistence of people is much greater with death than with life? Why not establish a necessary 'intimacy' between the fundamental curricular knowledge for students and the social experience they have as individuals?" - Paulo Freire.
