Saccenti’s volume belongs to the category of Begriffsgeschichte, the history of concepts, and more particularly to the debate over the existence or nonexistence of a conceptual shift in ius naturale to encompass a subjective notion of natural rights. The author argues
that this issue became particularly relevant in mid-twentieth century, first, because of the desire to delimit the totalitarian implications of legal positivism chez Hans Kelsen; second, in response to Lovejoy’s The Great Chain of Being and its progeny; and third, as a
result of a revival of neo-Thomistic and neo-scholastic perspectives sometimes labelled “une nouvelle chrétienté.”
