Robert Gilpin Quote

Powerful groups set constraints on and may even determine the actions of state authority. They constitute the society that is protected by the state; their particular concept of justice reigns. The definition and functioning of property rights tend to advance their interest and welfare.... the basic domestic function of the state is to define and protect property rights of individuals and groups.... The primary external function of the state is to protect the property rights and personal security of its members vis-à-vis the citizens and actions of other states.
