International law took shape not amid a multitude of competing models, but in an era when the state was the most developed and institutionally complete form of political organisation. This is why the state became the original model of legal personality. This was not a theoretical error, but a reflection of historical reality.
From here two extremes are possible - and both are false. Either the state is declared a unique and wholly special subject, or all subjects are levelled. More precisely, a third holds: the state is neither an exception nor a universal model, but the historically first fully developed instance of a more general process of institutional formation. Like the vertebrates in biology: not the universal model of life, yet not ceasing to be its most important example - simply having taken its place within a more general theory. On this view the "exceptions" of doctrine (international organisations, movements, peoples, the individual, the Holy See) cease to be annexes to a building and become different historical forms of a single process.
What, then, distinguishes the state most deeply? Not territory and not sovereignty, but the monopoly on coercion (the classic Weberian formula). Yet on a close reading it describes not subjecthood, but a means of securing normative order. And here arises what is perhaps the strongest question of the whole subject - posed with the utmost caution:
Is the capacity for coercion a necessary condition for the emergence of a stable normative order - or is it merely one of the technologies that have historically dominated its maintenance?
The thesis does not assert that coercion is unnecessary. It merely declines to treat as proven that no other mechanisms of stable order exist.
