The radical, committed to human liberation, does not become the prisoner of a 'circle of certainty' within which reality is also imprisoned. On the contrary, the more radical the person is, the more fully he or she enters into a reality so that, knowing it better, he or she can better 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 enter into 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.
— Pedagogy of the Oppressed by Paulo Freire (Page 39)
The best definition of a radical I have ever heard. I thought about my friend Ñukñu who to me is the most radical person I have ever met. I like to think as myself as radical but then that wouldn't be very radical of me. Freire talks about the differences between a sectarian and a radical. People on the left can be sectarians when they alienate others into believing that their 'truth' is the only truth.
