Psychoanalysis is not dead, but then again, it is no longer moving very quickly. Greenson relates this to the fate of new ideas. Clinical material is presented to illustrate the birth of new ideas; frustration and discontent in the individual seem necessary to the creation of new ideas. Freud as 'conquistador' is held up as the model of the innovative psychoanalyst. Always exploring new territory, he does not set out to destroy old ideas; rather he constantly reworks and revises his older theories, realizing the limitations of his own knowledge. Current 'schools' of psychoanalysis, i.e., orthodox, classical, Kleinian, neo-Freudian, are described and deplored. They become establishments, protected in their insularity from the 'false believers'. Each school resists intrusion of new ideas; there is lack of progress because there is a lack of openness to new and different points of view. It is no longer reasonable to defend or attack Freud's theories; it is reasonable only to pursue further learning.
