Only in the encounter of the people with the revolutionary leaders—in their communion, in their praxis—can this theory be built. - Paulo Freire

Almost never do they realize that they, too, 'know things' they have learned in their relations with the world.

Knowing, whatever its level, is not the act by which a subject transformed into an object docilely and passively accepts the contents others give or impose on him or her. Knowledge, on the contrary, necessitates the curious presence of subjects confronted with the world. It requires their transforming action on reality. It demands a constant searching. It implies invention and reinvention. It claims from each person a reflection on the very act of knowing.

Critical and liberating dialogue, which presupposes action, must be carried on with the oppressed at whatever the stage of their struggle for liberation.
