Both sovereignty and cosmopolitanism are conceptual constructions. Like any concept they may refer to, for example, actual facts or ideal elements with or without empirical existence. What appears to be the same very basic concepts in legal and political sciences and international relations are still discussed globally. These discussions seem to be centred on and disagree about the same concepts, in actual terms they are centred on conceptions of these concepts and therein the disagreement in their hermeneutics.
There are many definitions, views, and conceptions of sovereignty. The differences between these definitions or conceptions have to do with the frame of reference. For example, depending on the legal or political perspective, “sovereignty” may mean power or imply authority. Similarly, sovereignty can be viewed as internal or external, and as an attribute of a person, a body, a state or a supranational entity.
Bodin and Hobbes coined in the early Modern Age the current scholarly understanding of the concept of sovereignty. To illustrate the evolution of the term, a classical and a current definition of “sovereignty” follow:
“Aieltie or Sovereignty is the most high, absolute, and perpetual power over the citizens and subjects in a Commonwealth…”
“A Supreme authority in a state. In any state sovereignty is vested in the institution, person, or body having the ultimate authority to impose law on everyone else in the state and the power to alter any pre-existing law…In international law, it is an essential aspect of sovereignty that all states should have supreme control over their internal affairs…”
Any definition of sovereignty includes the concept of the highest, supreme, absolute authority in a territory and over a population. Within a territory, it means that lawmakers—i.e. the government—have the exclusive prerogative to create laws for these people. Externally, any other agent has the obligation not to interfere. From this very brief characterization, it is self-evident that sovereignty refers to normative elements such as national legal order and international legal agreements as well as factual ones such as territory and population.
In the same vein, unsurprisingly, scholarly literature uses the word “cosmopolitanism” very loosely. Claimed to start in Ancient Greece with Diogenes labeling himself as “citizen of the world” but, according to the Stoics, without giving up identifying local roots, the term suggests identification with different groups (such as family, neighborhood, city, state, region, world). Arguably, it is Kant who fathers the concept in modern times. In his Perpetual Peace scholars from different disciplines find epistemological, economic or commercial, legal, moral, ethico-theological, political and cultural cosmopolitanism.
