Paulo Freire addresses teachers here to discuss the most delicate aspects of educational practice, and he does so with the firmness and generosity that characterize his style.

Against the taboos, which end up producing weak and hesitant teachers, Freire defends the need for an authority that allows the teacher's confidence in his own knowledge and convictions and in his ability to bond with the students and propose other possible worlds.

Thus, the letters recover the taste of dialogue and the value of the transmission that emerges from experience. Educators and researchers will find in the reading of this book an invitation to become producers of understanding of the words of the author, which Siglo XXI publishes in a new edition.
