A certain body of mythology has emerged in recent years around Martti Koskenniemi's From Apology to Utopia (FATU). At its heart lies a group of received wisdoms that tell us that FATU should essentially be considered a work of postmodern scholarship, that it provides a typical illustration of the so-called deconstructivist approach, and that its single most significant contribution to the field of international legal theory lies in its discussion of the subject of legal indeterminacy. In this article, I seek to challenge and displace this set of narratives, by excavating and restoring to the surface FATU's original intellectual project: a highly ambitious attempt to revive the traditional enterprise of ‘legal science’ by marrying Kelsenian legal positivism with Saussurean structuralist semiotics. In doing so, it succeeded in developing a set of analytical idioms and reasoning protocols that gave the international law profession not only a reason but also the necessary intellectual materials to revolutionize its day to day understanding of the essential character of international legal practice. Thus, far from being a manifestation of any kind of postmodernist sensibility, FATU, I am going to argue, represents, in fact, the exact opposite of it.
