In *Between Therapist and Client*, Michael Kahn explores what is perhaps the most important aspect of therapy - the therapist-client relationship. As he traces the history of the clinical relationship from Freud to the present, Kahn shows how the enmity between the humanists and the psychoanalysts limited their therapeutic effectiveness - and how their recent reconciliation has opened up exciting new possibilities for the way therapists relate to their clients, pointing to a new period in the history of psychotherapy.
