Since the concept of the state has only in modern times reached its full development. It is best to define it in terms appropriate to the modern type of statue , but at the same time , in terms which abstract from the values of the present day, since these are particularly subject to change. The primary formal characteristics of the modern state are as follow: It possesses an administrative and legal order subject to change by legislation, to which the organized corporate activity of the administrative staff, which is also regulated by legislation, is oriented. This system of order claims binding authority, not only over the members of the state, the citizens… but also to a very large extent, over all actions talking place in the area of its jurisdiction. It is thus a compulsory association with a territorial basis. Furthermore, today, the use of force is regarded as legitimate only so far as it is either permitted by the state or prescribed by it.(1947:156)
