The twentieth century was deeply influenced by theoretical-practical and reflective developments in philosophical hermeneutics. It introduced a large range of problems, content and perspectives, on a vast referential and implicational (inter-)disciplinary scale, to enter into the real orbit of a philosophical koinè, not for a decennary or few decennaries (Vattimo), but for a century and more. It expressed the productivity, significance and heuristic strength of research and thought that hit different scientific domains, particularly (but not exclusively) the human and social sciences: from psychology to sociology, from psychoanalysis to literature, from semiotic to biblical exegesis, from anthropology to linguistics, from rhetoric to narratology, from history to law and from political theory to religion
