 While publishing short articles on the subject earlier in his career (for example the essay "De quelques formes primitives de classification" written in 1902 with Marcel Mauss), Durkheim's definitive statement concerning the sociology of knowledge comes in his 1912 magnum opus "The Elementary Forms of Religious Life".This book has as its goal not only the elucidation of the social origins and function of religion, but also the social origins and impact of society on language and logical thought.Durkheim worked largely out of a Kantian framework and sought to understand how the concepts and categories of logical thought could arise out of social life.
