This essay (so far unpublished) is an (updated) version of the conference presented at the XXIX Jornadas de la Asociación Argentina de Filosofía del Derecho: Verdad, Justicia y Derecho, which took place, from October 1 to 3, 2015, in Ushuaia, known as Tierra del Fuego, in Patagonia, Argentina, which was attended by Michele Taruffo, Jordi Ferrer Beltrán, Carlos Cárcova, Alicia Ruiz, Jorge Douglas Price, Eugenio Bulygin, Rodolfo Vigo, among others. Based on the assumptions and theoretical contributions that characterize the structural intersection of Law and Literature studies, this paper is divided into four parts: after a quick presentation of the proposal (Section I), some considerations are developed regarding the relationship between Law and Literature, more specifically about procedural narratives and the issue of truth (Section II); then, in order to illustrate how literature can teach jurists, we resort to the novel Blanco nocturno, by Ricardo Piglia, which serves to problematize the theme of law fiction with all its inherent singularity (Section III) and to formulate the conclusion of the essay (Section IV).
