Hobbes’ natural law theory has been discussed far and wide. Some interpreters ended up defining Hobbes as a natural law theorist, some others as a legal positivist. In this paper, I analyse the work of two important scholars, Howard Warrender and Norberto Bobbio, whose insights have stimulated an interesting debate about Hobbes’ political theory. Warrender gives God a central function in Hobbes’ political science. On his account, God is a lawmaker, his will is the source of a universal obligation, and (...) civil order is necessary to give force to the natural law that is the expression of divine will. In Bobbio’s interpretation, Hobbes is the first legal positivist of Modern age, as natural law is only ever given content by the sovereign’s will. Finally, I ask which is natural law and God’s function in Hobbes’ political thought, questioning some contemporary scholars in order to clarify Hobbes’ modernity. (shrink)
