Siegfried J. Schmidt is closely associated in Germany with the cross-disciplinary research programme of Radical Constructivism. In Histories&Discourses he carries out a change of perspective from media and communication studies to studies of culture and the philosophy of language.His 'rewriting' of constructivism shows that classical constructivism shares some fundamental assumptions with realism, and he creates a new vocabulary which allows us to understand how we construct truth, identity, ethics, etc., without using any point of reference which lies beyond our culture (our 'history and discourses').
