The Name of Things: Jottings in the Margin of Luigi Ferrajoli’s Principia Juris - The author examines certain aspects of the axiomatic theory of law developed in Luigi Ferrajoli’s monumental Principia Iuris, dwelling in particular on the theme of lacunae, on the concept of expectation, on conflicts between rights and on the definition of democracy. All these topics orbit around the notion of "subjective law" and how it relates to the notion of democracy, while each one calls attention to an awkward intersection that risks undermining the theory’s overall structure: in fact, the author believes that Luigi Ferrajoli’s theory of law is based on certain insufficiently justified and therefore questionable theoretical choices.
