GEMAS brings together sociologists engaged in research and teaching (principally at Paris-IV) and attracts numerous doctoral and post-doctoral students. The aim of the institute is the extension of empirical sociological knowledge within an evolving theoretical framework. There are three dominant registers of reflection : general sociological theory ; the epistemological and methodological foundations of the social, physical and life sciences ; and finally, the application of theory and methodology to the domains of collective action, norms, values, culture, mores, argumentation, knowledge, education, art, and social stratification.
