In 1625, in his book On the Law of War and Peace, Hugo Grotius asserted that human beings would have obligations βeven if we should concede that which cannot be conceded without the utmost wickedness, that there is no God, or that the affairs of men are of no concern to Himβ.2 But two of his followers, Thomas Hobbes and Samuel Pufendorf, thought that Grotius was wrong.3 However socially useful moral conduct might be, they argued, it is not really obligatory unless some sovereign authority, backed by the power of sanctions, lays it down as the law. Others in turn disagreed with them, and so the argument began.
