 Other of Machiavelli's readers have found no taint of immoralism in his thought whatsoever. Jean-Jacques Rousseau long ago held that the real lesson of The Prince is to teach the people the truth about how princes behave and thus to expose, rather than celebrate, the immorality at the core of one-man rule. Various versions of this thesis have been disseminated more recently. Some scholars, such as Garrett Mattingly (1958), have pronounced Machiavelli the supreme satirist, pointing out the foibles of princes and their advisors. The fact that Machiavelli later wrote biting popular stage comedies is cited as evidence in support of his strong satirical bent. Thus, we should take nothing Machiavelli says about moral conduct at face value, but instead should understand his remarks as sharply humorous commentary on public affairs. Alternatively, Mary Deitz (1986) asserts that Machiavelli's agenda was driven by a desire to “trap” the prince by offering carefully crafted advice (such as arming the people) designed to undo the ruler if taken seriously and followed.
