The author has had extensive experience in treating patients, as well as in teaching students in psychotherapeutic technics. The book is an outstanding example of organization and systematic presentation of a subject that is generally difficult to reduce to a workable classification. The author's viewpoint is not primarily that of the orthodox ego-psychiatrist, but is highly colored by a mechanistic behavioristic point of view with emphasis on conditioning as a most potent factor in determination of human reactions.
The author starts with five basic premises regarding human behavior. These are as follows: (1) that the organism seeks a point of equilibrium between itself and its environment (homeostasis); (2) that the person is incomplete and must therefore seek completion in relation with others; (3) that the organism responds as a whole to any stimulus no matter where applied; (4) that concepts of causality or event sequences must be broadened in order
