The second chapter of Paulo Freire's Pedagogy of the Oppressed (1970). The full text of the book is online here.
A careful analysis of the teacher-student relationship at any level,
inside or outside the school, reveals its fundamentally narrative
character. This relationship involves a narrating Subject (the teacher)
and patient listening objects (the students). The contents, whether
values or empirical dimensions of reality, tend in the process of being
narrated to become lifeless and petrified. Education is suffering from
narration sickness.
The teacher talks about reality as if it were motionless, static,
compartmentalized, and predictable. Or else he expounds on a topic
completely alien to the existential experience of the students. His task
is to "fill" the students with the contents of his narration --
contents which are detached from reality, disconnected from the totality
that engendered them and could give them significance. Words are
emptied of their concreteness and become a hollow, alienated, and
alienating verbosity.
