In the short introduction he has written for this book, Professor Hans Hoff comments: "Although I am certain it will provoke some lively discussion and even perhaps at times outright disagreement, it is singularly pleasing to me to see the basic concepts of medical psychology and of psychotherapeutic approaches reviewed from such an exceptionally original viewpoint." Would that this were so!
It is true that a number of original ideas are expressed. But, largely, these are sweeping, superficial, vaguely formulated conjectures apparently derived in their entirety from the author's introspection, intuition, and imaginative speculation. There can be no quarrel with the value of imagination as a source for new scientific ideas. To be useful, however, such models should be sufficiently clear and explicit so that some kinds of hypotheses can be derived which yield to test by observation and experiment. And certainly one has the right to expect logical consistency
