 Another suggestion sees Grotius as deeply concerned to refute scepticism about international law. Grotius was upset when the powerful French Cardinal Richelieu told him, “the weakest are always wrong in matters of state”. How is it that he can convince doubters such as Richelieu of the existence and force of a set of norms governing the conduct of governments both domestically and internationally? The argument will never be easily won but the burden may be lightened by sharing the load. If Grotius can show that so many people throughout history have accepted what the sceptic denies, then perhaps the force of numbers may change the sceptic’s mind.
