“But what does _Cadillac_ mean? Cadillac is the name of a hotel and of an automobile. A few days before in a country place my medical friend and I had been trying to hire an automobile, but there was none to be had. We both expressed the wish to own an automobile--again an unrealized ambition. I also recalled that the ‘Carrefour St. Lazarre’ always impressed me as being one of the busiest thoroughfares in Paris. It was always congested with automobiles. Cadillac also recalled that only a few days ago on the way to my clinic I noticed a large sign over a building which announced that on a certain day ‘this building was to be occupied by the Cadillac,’ etc. This at first made me think of the Cadillac Hotel, but on second sight I noticed that it referred to the Cadillac motor-car. There was a sudden obstruction here for a few moments. The word Cadillac reappeared and by sound association the word _catalogue_ occurred to me. This word brought back a very mortifying occurrence of recent origin, the motive of which is again blighted ambition. “When one wishes to report any auto-analysis he must be prepared to lay bare many intimate affairs of his own life. Any one reading carefully Professor Freud’s works cannot fail to become intimately acquainted with him and his family. I have often been asked by persons who claim to have read and studied Freud’s works such questions as: ‘How old is Freud?’ ‘Is Freud married?’ ‘How many children has he?’ etc. Whenever I hear these or similar questions I know that the questioner has either lied when he made these assertions, or, to be more charitable, that he is a very careless and superficial reader. All these questions and many more are answered in Freud’s works. Auto-analyses are autobiographies _par excellence_; but whereas the autobiographer may for definite reasons consciously and unconsciously hide many facts of his life, the auto-analyst not only tells the truth consciously, but perforce brings to light his whole intimate personality. It is for these reasons that one finds it very unpleasant to report his own auto-analyses. However, as we often report our patients’ unconscious productions, it is but fair that we should sacrifice ourselves on the altar of publicity when occasion demands. This is my apology for having thrust some of my personal affairs on the reader, and for being obliged to continue a little longer in the same strain.
