Dr. Waddington has presented us with a most stimulating article which has provoked a discussion so fascinating (and tangled) that I should greatly like to be allowed to take my part in it. Let it be stated at the outset that I approach the fray from the side of psycho-analytical theory and its cl"nical findings. From this point of view Dr. Waddington's statement of his psycho-analytical case, though partly correct, does not appear to be entirely accurate, which is not to be wondered at considering the language in which, as he justly remarks, psycho-analytical exposition is often couched, and also in view of the extreme unfamiliarity of the subject-matter and the piece-meal fashion in which Freudian psychopathology has evolved itself. I should like to begin by summarizing Dr. Waddington's statement of the psycho-analytical case and then to annotate his statement with such emendations as seem to me to be required.
