The classic foundational status that Hobbes has been afforded by contemporary international relations theorists is largely the work of Hans Morgenthau, Martin Wight, and Hedley Bull. They were not unaware that they were to some extent creating a convenient fiction, an emblematic realist, a shorthand for all of the features encapsulated in the term. The detachment of international law from the law of nature by nineteenth-century positivists opened Hobbes up, even among international jurists, to be portrayed as almost exclusively a mechanistic theorist of absolute state sovereignty. If we are to endow him with a foundational place at all it is not because he was an uncompromising realist equating might with right, on the analogy of the state of nature, but instead to his complete identification of natural law with the law of nations. It was simply a matter of subject that distinguished them, the individual and the state.
