I have repeatedly and gratefully acknowledged the efforts of the Zürich Psychiatric School in the spreading of psychoanalysis, especially those of Bleuler and Jung, and I do not hesitate to do the same today, even under such changed circumstances. It was certainly not the partisanship of the Zürich School which at that time first directed the attention of the scientific world to the subject of psychoanalysis. This latency period had just come to an end, and psychoanalysis everywhere became the object of constantly increasing interest. But whilst in all the other places this manifestation of interest resulted first in nothing but a violent and emphatic repudiation of the subject, in Zürich, on the contrary, the main feeling of the situation was that of agreement. In no other place was so compact a little gathering of adherents to be found, nowhere also was it possible to place a public clinic at the service of psychoanalytic investigation, or to find a clinical teacher who regarded the principles of psychoanalysis as an integral part of the teaching of psychiatry. The Zürich doctors became, as it were, the nucleus of the little band which was fighting for the recognition of psychoanalysis. Only in Zürich was there a possible opportunity to learn the new art and to apply it in practice. Most of my present-day followers and co-workers came to me via Zürich, even those who might have found, geographically speaking, a shorter road to Vienna than to Switzerland. Vienna lies in an eccentric position from western Europe, which houses the great centers of our culture. For many years it has been much affected by weighty prejudices. The representatives of the most prominent nations stream into Switzerland, which is so mentally active, and an infective lesion in this place was sure to become very important for the dissemination of the “psychic epidemic,” as Hoche of Freiburg called it.
