Summary

Machiavelli argues that a prince must be willing to abandon moral integrity and use craft and force to maintain power, because men are bad and will not keep faith. He presents two methods of contesting: by law, which is proper to men, and by force, which is proper to beasts; a prince must know how to use both natures, like the centaur Chiron who taught Achilles. The prince should imitate the fox to discover snares and the lion to terrify wolves, since relying solely on the lion is insufficient. Machiavelli draws heavily on Cesare Borgia’s conduct as a pattern for usurpers, and criticizes Louis XII for committing five capital errors in statecraft that led to his expulsion from Italy. The book systematically categorizes principalities—hereditary, mixed, new, ecclesiastical, civil—and advises on military organization, avoiding flatterers, and withstanding fortune. A reader takes away Machiavelli’s insistence that politics has no perfectly safe courses, only less dangerous ones, and that while crimes may win an empire, they do not win glory.

Key concepts

  • Two ways of contestingThe prince must contest by law (proper to men) and by force (proper to beasts), using both natures because one without the other is not durable.
  • Fox and lionThe prince must be a fox to discover snares and a lion to terrify wolves, since the lion cannot defend against snares and the fox cannot defend against wolves.
  • Faith of princesA wise lord cannot keep faith when observance may be turned against him and the reasons for the pledge no longer exist, because men are bad and will not keep faith with him.
  • Five capital errors in statecraftThe specific mistakes Louis XII made in Italy that caused him to be driven out, summarized in *The Prince*.
  • Pattern of Cesare Borgia’s conductThe actions of Cesare Borgia, Duke Valentino, are cited as the best precepts for usurpers who wish to keep seized states.
  • Necessary wars are just warsThe arms of a nation are hallowed when it has no other resource but to fight, and necessary wars are just wars.

the prince himself, or of others, or else by fortune or by ability. CHAPTER II. CONCERNING HEREDITARY PRINCIPALITIES
