This essay analyzes the representation of Law and the Lawyer in Les Fruits si doux de l’arbre à pain, a novel in which the main character is a judge. The first objective is to examine the relationship of homology or opposition between literary fiction and the Law as the later stands as a scientific discourse. The second objective is to show, through the analysis of the trajectory of Raymond Poaty, the main character of the novel, how the literary fiction can be a mirror or a space of reflexivity which can help the Law and the Lawyer to escape intradisciplinary tautologies.
