Abstract
In this article I discuss the nature and sense of legal reasoning as reasonableness, i.e. as judgement and equilibrium between normativity and factuality, and as constant approximation between these two dimensions. By phrasing the intertwinement between legal hermeneutics and the nature and function of writing, the structure of the article is constructed so that the focus is on the changes currently occurring with the so-called ‘digital revolution’: in imagining a juridical system administrated through data analysis and algorithms, some contradictions emerge, especially concerning the nature, sense and task of legal hermeneutics. The current shift of paradigm should be first of all addressed starting from the grammatological nature of the revolution at stake. Only from this perspective can the shift be entirely grasped and, at the same time, only from this perspective can the methodological conundrum be deconstructed.
