Murray Bowen developed a new theory of human behavior. It uses natural systems thinking to combine knowledge of man as a product of evolution with facts about human behavior derived from many disciplines. The book’s focus on the family emotional system as an integrative concept is precisely the right approach. Vigorous exchange between top-notch scientists and seasoned Bowen theorists/therapists has been happening for forty-odd years. Thank goodness this exchange has finally been reflected in a book. Each chapter by the scientists and Bowen theorists can stand alone, but the combination of authors from diverse fields makes for a very good read that generates a unique comprehension of the depth and breadth of Bowen family systems theory.
