The central concern of structural functionalism may be regarded as a continuation of the Durkheimian task of explaining the apparent stability and internal cohesion needed by societies to endure over time. Societies are seen as coherent, bounded and fundamentally relational constructs that function like organisms, with their various (or social institutions) working together in an unconscious, quasi-automatic fashion toward achieving an overall social equilibrium. All social and cultural phenomena are therefore seen as functional in the sense of working together, and are effectively deemed to have "lives" of their own. They are primarily analyzed in terms of this function. The individual is significant not in and of himself, but rather in terms of his status, his position in patterns of social relations, and the behaviours associated with his status. Therefore, the social structure is the network of statuses connected by associated roles.
