"If education is the relation between Subjects in the knowing process mediated by the knowable object, in which the educator permanently reconstructs the act of knowing, it must then be problem-posing. The task of the educator is to present to the educatees as a problem the content which mediates them, and not to discourse on it, give it, extend it, or hand it over, as if it were a matter of something already done, constituted, completed, and finished."
