For its second thematic Issue, the Review Sociétés plurielles has chosen to deal about the Epistemologies of the Plural, which can be different according to the different Branches of Learning. Six Articles, dealing with various Topics, have been selected, appealing to Sociology, Philosophy, Anthropology, visual Arts, and Sciences of Information and Communication. The Authors are questioning the Duality Singular/Plural or Similar/Different at the University, in the Enterprise or in the rural World, in the Objects of cultural Consumption as well as in the Field of contemporary Photography, or in the Typology developed in early XXth Century Anthropology. All of them deal with the Question of the Plural in our Societies with their own Tools and Problematics.
