The role of the educator is one of tranquil possession of certitude in regard to the teaching of not only contents but also of 'correct thinking.'
Paulo FreireNo one can learn tolerance in a climate of irresponsibility, which does not produce democracy. The act of tolerating requires a climate in which limits may be established, in which there are principles to be respected. That is why tolerance is not coexistence with the intolerable. Under an authoritarian regime, in which authority is abused, or a permissive one, in which freedom is not limited, one can hardly learn tolerance. Tolerance requires respect, discipline, and ethics.
