First published in 1986. When the first edition of this book was published in 1964, it was seen as being in the area of irregulars in the psychotherapy field as behavior therapies had not yet found a place in the established genre. The new edition catches up on twenty years of academic and scientific study which have done much to resolve conflict and validate the major modes of psychotherapy; spinoffs of familiar therapies have moved the field toward synthesis, integration, and ecumenism, on one hand (Cognitive Behavior Therapies), and toward antinomian religions and recreation on the other.
