E. Durkheim's "L'Education Morale" is the lecture in the primary course on the Science of Education which he had delivered in the Sorbonne, in 1902-1903. The lecture consists of Introduction and two parts. Intending to establish the moral education on the basis of secular morality in the introduction, he proposes, "When we attempt to secularize the moral education, we must discover moral forces, release them from religious symbols, and explain them in terms of rationality. In rationalizing morality, we must not loose some of its component elements, but we must enrich it with new elements." In the first part of the lecture, he analyzes the secular morality and points out its three elements: "l'esprit de discipline", "l'attachement aux groupes sociaux" and "l'autonomie de la volonte". Symmetrically to the first part, the second part comprises three sections: "sur l'esprit de discipline", "sur l'esprit d'abnegation" and "sur l'autonomic de la volonte", studied primarily from the pedagogic viewpoint. We may be able to look into the basic problems in his sociology through the study of his sociological approach to the moral education.
