Sovereign state
The state as "quasi-abstract"

It has been argued that one potential reason as to why the existence of states has been controversial is because states do not have a place in the traditional Platonist duality of the concrete and the abstract. Characteristically, concrete objects are those that have a position in time and space, which states do not have (though their territories have a spatial position, states are distinct from their territories), and abstract objects have a position in neither time nor space, which does not fit the supposed characteristics of states either, since states do have a temporal position (they can be created at certain times and then become extinct at a future time). Therefore, it has been argued that states belong to a third category, the quasi-abstract, that has recently begun to garner philosophical attention, especially in the area of Documentality, an ontological theory that seeks to understand the role of documents in understanding all of social reality. Quasi-abstract objects, such as states, can be brought into being through document acts, and can also be used to manipulate them, such as by binding them by treaty or surrendering them as the result of a war.
