Paulo Freire was a Brazilian educator known for his critical views on education, particularly his opposition to 'banking education,' where students are passive recipients of knowledge. He advocated for a problem-posing approach that encourages dialogue and critical consciousness, aiming to empower learners to transform their societal realities. Freire's philosophy emphasizes the importance of self-education, critical literacy, and the need for education to challenge existing power structures to promote humanization and freedom.
