The concept of symbolic culture draws from semiotics, and emphasises the way in which distinctively human culture is mediated through signs and concepts. The symbolic aspect of distinctively human culture has been emphasised in sociology by Emile Durkheim, Claude Lévi-Strauss, Clifford Geertz and many others.
