This is a thought-provoking and stimulating little paper. The author is not so much "characterizing our ignorance," as stating quite definitively that we should recognize our ignorance and that the ignorance is not due to any defect on our part, but rather to the nature of what we are studying. Without knowing it, the author touches on some of the most crucial elements of Waelder's paper on multiple function: that changes in the superego result in changing the gestalt, which results in changes in other parts of the psychic apparatus, leading in turn to further changes of the superego. Thus, this never-ending process accounts for the difficulties with which we are continually confronted.
