First published in Portuguese in 1968, was translated and published in English in 1970. Paulo Freire's work has helped to empower countless people throughout the world and has taken on special urgency in the United States and Western Europe, where the creation of a permanent underclass among the underprivileged and minorities in cities and urban centers is ongoing. This 50th anniversary edition includes an updated introduction by Donaldo Macedo, a new afterword by Ira Shor and interviews with Marina Aparicio Barberán, Noam Chomsky, Ramón Flecha, Gustavo Fischman, Ronald David Glass, Valerie Kinloch, Peter Mayo, Peter McLaren and Margo Okazawa-Rey to inspire a new generation of educators, students, and general readers for years to come.
