In this chapter, Machiavelli uses "beasts" as a metaphor for unscrupulous behavior. He states that while lawful conduct is part of the nature of men, a prince should learn how to use the nature of both men and beasts wisely to ensure the stability of his regime. In this chapter however, his focus is solely on the "beastly" natures. In particular, he compares the use of force to the "lion", and the use of deception to the "fox", and advises the prince to study them both. In employing this metaphor, Machiavelli apparently references "De Officiis" by the Roman orator and statesman Cicero, and subverts its conclusion, arguing instead that dishonorable behavior is sometimes politically necessary.
