ABSTRACT
In Arnold Cooper's 1982 Presidential Address to the American Psychoanalytic Association entitled, "Psychoanalysis at 100: Beginnings of Maturity" (Cooper, 1982), he reviewed the evidence of increasing maturity in psychoanalysis, the inevitable resistance to change, the role of controversy in the evolution of ideas, and the growing importance of scientific data as it relates to theory-building. He points out - correctly, in my opinion - that one aspect of our profession's maturity is an increasing difficulty in defining the boundaries between psychoanalysis and other disciplines. Many of these issues are brought sharply into focus in any attempt to discuss the papers by Drs. Ekstein, Nunn, and Shane on the subject of change and integration in theoretical concepts.
