(...) social institutions are a totality of perpetual rules which are important for the maintenance of the structure and main values of the society. Social institutions include thoughts on how to reach the aims that are considered significant. The process of a social practice to become regular and perpetual enough for being a social institution is called institutionalization (Johnson, 2000:157). The main social institutions, family, religion, economy, education, health and politics exist in every society, although sometimes they appear in different forms.
C.W.Mills used the "sociological imagination" phrase to explain the need to move away from viewing problems as personal and to recognize them as social issues. The sociological imagination enables us to grasp history and biography and the relations between the two within the society.
