This paper puts emphasis on Paulo Freire’s educational thoughts, philosophy, aims of education, concepts and theories of education, his ideas on critical pedagogy and comparison with the other great educators- Rabindranath Tagore, Rishi Aurobindo, and Rousseau. The method of this study was a systematic literature review.

At the same time, the comparison with the three great educators makes the Paulo Freire’s educational thoughts unique, distinct, and significant.
