Chapter 3 is used to expand on Freire's idea of dialogue. He first explains the importance of words, and that they must reflect both action and reflection. Dialogue is an understanding between different people and it is an act of love, humility, and faith. It provides others the complete independence to experience the world and name it how they see it. Freire explains that educators shape how students see the world and history. They must use language with the point of view of the students in mind. They must allow "thematic investigation": the discovery of different relevant problems and ideas for different periods of time. This ability is the difference between animals and humans. Animals are stuck in the present unlike humans who understand history and use it to shape the present. Freire explains that the oppressed usually are not able to see the problems of their own time, and oppressors feed on this ignorance. Freire also presses the importance of educators not becoming oppressors and not objectifying their students. Educators and students must work as a team to find the problems of history and the present.
