We have endeavored to demonstrate the teaching value of applying concepts derived from general systems theory to those derived from psychoanalytic theory. The construction of an Outline of Personality Organization as a hierarchically ordered complex system enabled the investigators to develop a systematic approach to the psychoanalytic concepts of adaptation and defense. This method has been shown to provide for the ordering of data pertinent to psychoanalysis of whatever source, and to be productive of indicators for further research work to test hypotheses derived from psychoanalytic theory. Part II demonstrates the application of this method to clinical material.
