The purpose of this thesis is to discuss in depth the issues of civic education and public education in light of Condorcet’s philosophy. Condorcet proposed the revolutionary plan of education reform in the period of the French Revolution. His philosophy is based on republican thought. The republic rests on the sovereignty of the people; people with sovereignty should receive intelligence and be educated for that. Therefore, Condorcet has planned educational programs to enhance people's ability to use reason, that is, “people's reason”, through public education, and to sublimate people and nation into enlightenment rationality. According to Condorcet, there is no true political and social space for citizens without public education, and there are only blind people who are confiscated by dictators. In this case, the citizen falls into anti-enlightenment which is adhered to the limit of immediate utility. Autocracy is always parasitic to the ignorance of citizens. Therefore, the role of public education must be the development of reasoned and free will. The purpose of public education is not to teach the doctrine of civic religion, but to teach all people how to use their reason, teach human rights, and teach people how to judge freely. In this sense, Condorcet's educational philosophy is civic education mediated by people's reason.
