The main interest of functional sociology has been culture as norms, values and a way of lifestyle rather than culture as high culture. Emile Durkheim is accepted as the founding father of functional approach in sociology. He addressed some basic questions about how culture came into being in his work, Primitive Classification, written with Marcel Mauss, his nephew and the most important student. According to them, culture only became possible when human communities began to separate and classify things in their environment.
