• This paper intends to critically discuss some points of the contemporary thesis concerning constitutional hermeneutics and methodology of law. Once identified some authors and the lines of argumentation affiliated grosso modo to the linguistic turn and rhetoric, as well as the core of the transcendental powers of communication (v.g. N. MacCormick, R. Alexy, K. Günther), the objective is to identify some dialogue with economics and political science, enlightened by recent researches about Hegel-Marx interpretations of social life. Of course the discussion inevitably passes through methodological questions, opposing analytics vs. dialectics, idealistic vs. realists standpoints. In a effort to foment the inclusive dialogue between points of view concerning the concept of law that may create (not necessarily) radical opponents, the lines of conclusion intents to revisit some foundations of Hegelian "method" (so to speak) and intends to give a modest contribution to a more profound analysis of the relations between sein and sollen categories, in order to enrich the discussions about technology and social life, specially the life of the law nowadays.
