A “medical moment”: Guicciardini and Lycurgus' knife

The article explores the role of the Spartan example in Guicciardini's political thought, giving a particular attention to his early writings. Examining a series of medical metaphors Guicciardini uses in the analysis of the state, the author uncovers Plutarch as their main source. It is argued that Plutarch, and his description of Lacedaemon, exercised a major influence in the formation of Guicciardini's political ideas. The author focuses on the crucial issue of the usage of “Lycurgus' knife,” while answering two key questions: (1) the feasibility of constituting a republic modelled on Sparta; (2) the legitimacy of the use of force in the cases of extreme necessity. On (2), Guicciardini's views are compared with Machiavelli's, and the difference in their understanding of necessità pointed out.
