The origin of the political
The social sciences have to include also the field of the political. Since Plato both the social and the political order, even though seen as different, are considered as grounded in the human nature, but the emergence of the political from the primary social order and the relatively natural attitude attached to it has never been explained in a satisfactory way. The Schutzian approach to mundane phenomenology in general and his analysis of the relationship between in-groups and out-groups in particular helps to bridge this gap.
