The initial problem which motivated the writing of this thesis arose from reading of Emile by Rousseau. In this work, it was possible to detect the influence of different theoretical approaches, such as rationalism and empiricism, inspiring the development of the educational plan designed by Rousseau for his imaginary student (Emile). The very core question of the present thesis regards to whether there was a theory of knowledge pertaining to Rousseau’s philosophical thinking and, if so, how it was related to (...) his theories of education. In the set of his oeuvre, Rousseau’s affiliation to authors like Descartes, Leibniz, Locke and Malebranche, as well as Condillac, Diderot, D’Holbach and Helvétius was discovered. As the reading of the great philosophical work of Rousseau progressed, an original knowledge theory was discovered, of the kind which accepts the coexistence of opposite thoughts. Pedagogy, in the context of (the work) Emile, arose out of the miscellany of such theories and also for the intense philosophical maturing process on the core of Rousseau’s thinking. This study intended, therefore, to understand the origin and development of Rousseau’s theory of knowledge, and also to figure out how the philosopher formulated his theories on Education, especially in Emile. The object of this research, materialized through the extensive bibliography of the Swiss philosopher, was intensively read and analyzed. The methodology used was that of comparative, descriptive and critical documentary research of the mentioned authors. This research is divided into three sections: the first one intends to investigate the philosophical influence from different authors on the foundations of Rousseau’s epistemology; the second section addresses Rousseau’s theories of Education; the third and final part investigates the link between theory of knowledge and Education within Rousseau’s philosophical thought. -/- .
