There is no true word that is not at the same time a praxis. Thus, to speak a true word is to transform the world.

Finally, it is important to make it clear that imagination is not an exercise for those detached from reality, those who live in the air.

[T]he more radical the person is, the more fully he or she enters into reality so that, knowing it better, he or she can transform it. This individual is not afraid to confront, to listen, to see the world unveiled. This person is not afraid to meet the people or to enter into a dialogue with them. This person does not consider himself or herself the proprietor of history or of all people, or the liberator of the oppressed; but he or she does commit himself or herself, within history, to fight at their side.
