Network therapy flourished in the U.S. during the 1970s, but has since dwindled there and begun to find new applications in Europe, especially in the Nordic countries. State social and healthcare systems, in developing deep vertical expertise, seems to build up a need for complementary horizontal expertise. The latest theories of sociology are used to analyze the need for networking, with the focus on language and dialogue as specific form. Two approaches developed in crisis service for psychotic patients (Open Dialogue) and in consultation for stuck cases in social care (Anticipation Dialogues), are dealt with. What becomes essential seems no longer to be the therapeutic method itself but the ability to see the polyphonic nature of clients' reality. In this respect, language--and dialogue as a specific form of being in language--as the focus of treatment, makes the practical forms of different approaches secondary.
