While Rotenberg acknowledges that it is legitimate to focus on one cognitive-rational or one narrative-storytelling therapeutic method in the course of therapy, he argues that a comprehensive theory of psychotherapy should include treatment possibilities for both rational and irrational manifestations of behavior, thereby engulfing all aspects of human behavior. For Rotenberg, a person's life becomes the "text," subject to being read and interpreted. If that person wishes to change his or her behavior via psychotherapy, then a hermeneutic system must be employed to understand that person's life. However, many systems interpret a person's life according to the particular theory espoused by the therapist. Rotenberg, in contrast, introduces a balanced theory bridging the rational and the irrational.
Between Rationality and Irrationality emphasizes that it is more important for a therapist to learn his client's own "language" than to impose his own doctrinaire interpretation.
