This volume of the Works contains the turning point that allowed Carlo Sini to inaugurate an original philosophical path, collecting the legacy of the hermeneutic (with particular reference to Heidegger) and pragmatist (with particular reference to Peirce) tradition. The alternative to relativism takes shape in a new conception of truth itself, understood as an always determined and situated experience, which has both the partiality of its own historical-practical position and the fullness of the meaning that configures the world without residues.
