Countless concerns brought me to the critical ontology of man. Enquiries about today's society led me to the need to look to history for some connections. Questions in various areas of human activity led me to possible relationships of action and consequences, the tendencies of which led me to consider the need for human, non-institutionalised education in order to bring about social transformation. My small experience in the field of education has prompted reflections and analyses that converge in other areas of knowledge such as philosophy, history, economics, sociology, anthropology, psychology and international relations. In this essay, I feel that there is a need to review public education policies in Brazil, especially with regard to the crucial phase for young Brazilians during their secondary education, which is the choice and training for work. It is necessary to think about all pedagogical activities in order to promote a democratic and emancipatory education in a process of permanent liberation.
