Since 1955, moving from early work in psychopharmacology to studies of clinical method and the psychiatric schools, Leston Havens has been working toward a general theory of therapy. It often seems that twentieth-century psychiatry, sect-ridden, is a Tower of Babel, as Havens once characterized it. This book is the distillation of long years of thought and practice, a bold yet modest attempt to delineate an "integrated psychotherapy."
